Description

  The present invention relates to a game device, a game processing method, and a program suitable for estimating a player's movement according to an operation state of an operation target.

  2. Description of the Related Art In recent years, games have become widespread that allow players not only to input instructions by operating buttons and keys but also to give instructions by moving the entire body. For example, Patent Document 1 discloses an input device in the form of a so-called balance board in which an instruction is input by a player standing on a platform and applying a load.

JP 2009-109399 A

  In the input device disclosed in Patent Document 1, when the player is placed on the platform, the balance state of the load applied to the plurality of built-in load sensors is changed, and the position of the center of gravity of the player's weight is detected. However, depending on the player's posture and movement, the movement of the load is small and within the detection error range, or the movement of the load is not detected, so it may be difficult to determine whether the movement is intended by the player. It was.

  The present invention solves such problems, and an object of the present invention is to provide a game device, a game processing method, and a program suitable for estimating a player's movement according to an operation state of an operation target. .

  In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

A game device according to a first aspect of the present invention includes a pattern storage unit, a detection unit, and an estimation unit.
The pattern storage unit stores in advance a plurality of patterns in the order of a plurality of operation objects arranged at predetermined positions and designating operation objects to be operated by the player.
The detection unit detects the operation state of the operation target for each of the plurality of operation targets.
When it is detected that a plurality of operation objects have been operated, the estimation unit estimates an operation object to be operated next by the player based on the order of the detected operations and the stored pattern.

An input device (generally called “controller”) having a plurality of operation objects is connected to the game device of the present invention.
The operation target is, for example, a button or key in a touchpad type input device held by the player, a gripping type input device itself that the player holds and swings, or a mat type that the player stands on and steps on with his feet. It is a button in an input device or a panel with a built-in load sensor.
The operation state includes, for example, a state indicating which button is pressed in the touch pad type input device, a state indicating a swing direction and a swing magnitude in the grip type input device, and a mat type input device. The state indicating which button or panel is being depressed or the state indicating the magnitude of the load.

When it is detected that some of a plurality of operation objects have been operated, the order of the detected operations is compared with a pattern prepared in advance, and the next is detected according to the comparison result. It is estimated which operation object will be.
For example, when two operation objects are operated continuously, it is estimated which operation object is operated (third) thereafter.
For example, when three operation objects are operated continuously, it is estimated which operation object is operated (fourth) thereafter.
For example, when three operation objects are operated continuously, it is estimated which operation object is operated between the first and second or between the second and third.
However, it is not limited by the present invention that the number of operation objects to be operated continuously is estimated as the next operation object.

According to the present invention, it is possible to appropriately estimate the operation target to be operated next by the player from the detected order. The game device can produce a game in accordance with the movement that the player will perform.
For example, in a game where a predetermined number of buttons are pressed in order and the game task is achieved, even when it is not detected that the buttons are pressed in order due to noise or the like, a predetermined ratio or more It is possible to easily realize such a specification that the game task is considered to be achieved if the two match.

The reference time may be determined based on an operation detected by the detection unit.
If no operation is detected within the reference time after estimation by the estimation unit, an image representing the estimated next operation target is displayed, and any of the operations within the reference time after estimation by the estimation unit is performed. When the operation is detected, a display unit that displays an image representing the detected operation target may be further provided.

In the present invention, even when a plurality of operation targets are operated, if the elapsed time between the operations is longer than the reference time, the operations are not a series of operations but separate operations. Are treated as
If the second operation is performed after the first operation is performed and before the reference time has elapsed, the first operation and the second operation are regarded as a series of operations. Then, the third operation is estimated based on the first operation and the second operation.
According to the present invention, it is possible to appropriately estimate the player's movement according to the operation state of the operation target.
For example, even if the player has performed multiple operations, the player has intentionally input separate instructions or one instruction (such as an instruction of a special move command) that is indicated by a series of operations. There are cases in which it is not clear. However, by setting the reference time, the player's intention can be estimated appropriately.

  The game apparatus may further include a calculation unit that calculates a reference time based on the detected operation time interval.

That is, the above-described reference time is obtained according to the detection result, and may be a different value each time. Then, a degree of freedom is given to the estimation processing by the game device, and more flexible estimation can be performed.
The reference time may be a predetermined fixed value.

The game apparatus may further include a history storage unit that stores a history of the order of detected operations.
Then, the estimation unit may add the estimated operation target to the stored history.

For example, the history storage unit stores the order of the most recent predetermined number of operations as a history.
The history storage unit may store the order of operations as a history in association with the time when each operation is detected.
The history storage unit may store the order of operations as history in association with identification information (player name, etc.) of the player who performed each operation.
According to the present invention, the game apparatus can perform more flexible estimation.

  The estimation unit estimates an operation target to be operated next by the player when it is detected that an operation target of the first threshold number or more and the second threshold number or less is sequentially operated among the plurality of operation objects. May be.

That is, as a condition for performing estimation by the estimation unit, it is possible to determine how many of a plurality of operation objects are to be estimated.
According to the present invention, it is possible to reduce the processing performed by the game device, and to appropriately estimate the operation target to be operated next by the player.

A detection part may detect the magnitude | size of the load to the said operation target by a player about each of several operation target as an operation state.
Then, the estimation unit may estimate an operation target to be operated next by the player based on each detected magnitude of the load.

In the input device (controller) used in the present invention, an instruction is input by the player standing on the platform and applying weight.
According to the present invention, the player can input an instruction by an intuitive operation. The game apparatus can appropriately estimate the operation target that the player intends to operate next.

  The estimation unit may obtain a center position of a load on a plurality of operation targets by the player based on the detected load magnitude, and may estimate based on the obtained center position.

That is, the position of the center of gravity of the load applied to the plurality of operation objects is handled as the place designated by the player.
According to the present invention, the player can input an instruction by an intuitive operation. The game apparatus can appropriately estimate the operation target that the player intends to operate next.

A predetermined estimation target region may be set in a region occupied by a plurality of operation targets.
Then, the estimation unit may estimate an operation target to be operated next by the player when the obtained center position is within the estimation target region.

That is, even in the area occupied by a plurality of operation objects, the above estimation process is not performed unless the position of the center of gravity is within the predetermined estimation object area. In that case, the detection result by the detection unit is used for the progress of the game, and the estimation process by the estimation unit is omitted.
According to the present invention, it is possible to reduce the processing performed by the game device, and to appropriately estimate the operation target to be operated next by the player.

  The game device may further include a game progression unit that advances the game based on the detection result by the detection unit and the estimation result by the estimation unit.

That is, not only the detection result of which button the player has pressed, but also which button the player is trying to press or which button the user is trying to press can be reflected in the game.
Thereby, for example, the game device can present game advice and hints according to the detection result or the estimation result. Further, the game device may determine the player's score according to the detection result or the estimation result. Note that how the detection result or the estimation result is reflected in the game is not limited by the present invention.

The game processing method which concerns on the other viewpoint of this invention is a game processing method performed with the game device which has a memory | storage part, a detection part, and an estimation part, Comprising: A detection step and an estimation step are provided.
The storage unit stores in advance a plurality of patterns in the order of a plurality of operation objects arranged at a predetermined position and designating the operation objects to be operated by the player.
In the detection step, the detection unit detects the operation state of the operation target for each of the plurality of operation targets.
In the estimation step, when the estimation unit detects that a plurality of operation targets are operated in the detection step, the player tries to operate next based on the order of the detected operations and the stored pattern. The operation target to be estimated is estimated.

  According to the present invention, it is possible to appropriately estimate the operation target to be operated next by the player from the detected order. The game device in which the game processing method of the present invention is executed can produce a game in accordance with the movement that the player will perform.

Next, an overview of the controller 105 used in the present embodiment will be described.
FIG. 2A is a diagram illustrating the appearance of the controller 105. The controller 105 used in this embodiment is a so-called “balance board” that is installed on the floor and receives instructions when the player stands on the platform 201 and steps on any place or puts weight on the platform. It is an input device having a shape of "".

  The controller 105 includes a plurality of load sensors. In the load sensor, strain due to deformation of the strain gauge according to the magnitude of the load is converted into a voltage change, and the magnitude of the load applied to the mounting table 201 is acquired by this voltage change.

  In the present embodiment, the mounting table 201 is divided into four regions 202A, 202B, 202C, and 202D, and one load sensor is built in each region. When the player stands on the mounting table 201, the magnitude of the load is detected by each load sensor provided in each of the areas 202A to 202D.

If the player is accurately standing at the center of the mounting table 201, the load applied to each load sensor should be equal.
However, actually, when the player stands on the reference standing positions 203A and 203B with both feet, the position of the feet is biased in a certain direction, or the position of the center of gravity of the player is tilted in a certain direction. Further, in a game in which the player inputs an instruction by changing the posture when standing on the platform 201, the position of the center of gravity is intentionally tilted.
Thus, the magnitude of the load applied to each load sensor varies depending on the position where the player stands and the posture of the player.

For example, when a player standing on the platform 201 turns his / her hip clockwise, the regions including the center of gravity position of the load detected by the load sensor are, for example, the region 202A, the region 202B, the region 202C, the region 202D, It is expected to move in this order.
Conversely, when the player turns his back counterclockwise, the region including the center of gravity position of the load detected by the load sensor moves, for example, in the order of region 202D, region 202C, region 202B, and region 202A. It is expected that.
That is, the information processing apparatus 100 can estimate the change in posture that the player would have taken from the change in the center of gravity position of the load detected by the controller 105.

By the way, depending on how the player's hips are turned, that is, depending on how the center of gravity changes, the amount of change in the center of gravity falls within the expected error range, and the change in the center of gravity cannot be fully captured. There is.
Further, in a normal human posture, both feet are placed at the reference standing positions 203A and 203B. Therefore, the movement of the center of gravity between the areas 202A and 202B and the movement of the center of gravity between the areas 202C and 202D are compared. Although it is easy to grasp, the movement of the center of gravity between the front and rear direction of the human, that is, between the areas 202A-202D and the movement of the center of gravity between the areas 202B-202C tend to be relatively difficult to grasp.
Therefore, in the present invention, even if the amount of change in the center of gravity position cannot be detected sufficiently, the posture change that the player would have taken can be simplified by using the history of movement of the center of gravity position as will be described later. So that it can be estimated.

  The controller 105 used in this embodiment includes four load sensors, and each load sensor is fixed so as to be in contact with the four corners of the mounting table 201. However, the number of load sensors and the manner of arrangement of the load sensors are arbitrary. is there.

  It is also possible to use a balance board type controller 105 as shown in FIG. 2A in combination with a controller having another shape.

FIG. 2B is a schematic diagram of another mat type controller (hereinafter referred to as “mat”) used by being connected to the information processing apparatus 100 of the present embodiment.
Similar to the controller 105, the mat is installed on the floor or the like. On the mat, a left button 251, a lower button 252, an upper button 253, a right button 254, and the like are arranged. In general, an instruction is input to the mat when the player steps on the foot. However, the player can also input instructions by pressing each button with his hand.

  For example, the balance board type controller 105 shown in FIG. 2A is stacked and arranged on the center portion of the mat shown in FIG. 2B (the portion in which the dotted circle is drawn in FIG. 2B). Thus, one player can use the two controllers without difficulty.

  In addition to the balance board type controller 105 shown in FIG. 2 (a) and the mat shown in FIG. 2 (b), for example, a remote control type controller that is held and operated by a hand, or a touch pad type held by both hands. A controller or the like may be further connected to the information processing apparatus 100 for use.

  Next, a functional configuration and the like of the game apparatus 300 according to the present embodiment realized by the information processing apparatus 100 having the above configuration will be described.

  FIG. 3 is a diagram illustrating a functional configuration of the game apparatus 300. The game apparatus 300 includes a pattern storage unit 301, a detection unit 302, and an estimation unit 303.

  The pattern storage unit 301 stores in advance a plurality of patterns in an order in which a plurality of operation objects arranged at predetermined positions should be operated by the player. The external memory 106 or the RAM 103 functions as the pattern storage unit 301.

The operation target is generally a button, key, switch, or the like that is used by a player to input an instruction. In this embodiment, the operation target includes four areas 202A, 202B, 202C, and 202D in the balance board type controller 105. Equivalent to.
The “operation by the player” referred to in the present invention includes pressing, pressing, switching, contact, swinging and the like on the operation target by the player.

  The operation target is arranged at a predetermined position. In the present embodiment, the four regions 202A, 202B, 202C, 202D in the balance board type controller 105 are fixed so as to be in contact with the four corners of the mounting table 201, respectively.

  Specifically, the order to be operated by the player is, for example, “the order in which the area including the center of gravity of the load moves is the first in the area 202A, the second in the area 202B, and the third in the area 202C. The fourth order is the area 202D ".

FIG. 4 is a specific example of a pattern stored in the pattern storage unit 301. Area 202A is abbreviated as “A”, area 202B as “B”, area 202C as “C”, and area 202D as “D”. For example, the group R includes four patterns of item numbers 1 to 4, and the group L includes five patterns of item numbers 1 to 5.
In the following description, a pattern stored in the pattern storage unit 301 is expressed as “{A, B, C}” using a symbol {}.

  Within the same group, movement patterns of postures (motions) presumed to be performed by the player and similar to each other are classified.

In FIG. 4, each pattern included in the group R represents a clockwise movement or a movement that can be estimated to be approximately clockwise, and each pattern included in the group L represents a counterclockwise movement or approximately left. It represents the movement that can be estimated to be around.
Furthermore, the pattern included in the group R represents the movement of the center of gravity position that will be detected when the player rotates his / her hip clockwise, and the pattern included in the group L includes Represents the movement of the center of gravity position that would be detected when rotating.

Note that FIG. 4 is an example, and other patterns can be defined. There is no limit to the number of groups and the number of patterns that can be included in the same group.
For example, the pattern {B → C → D → A}, the pattern {B → C → A}, etc. are all clockwise movements or movements close to the right, and may be included in the group R.

  Regarding the specific configuration of patterns stored in the pattern storage unit 301 and grouping of patterns, for example, the game creator performs a test in advance and compares the change in posture and the method of change in the center of gravity position. , It is desirable to be predetermined.

  The detection unit 302 detects the operation state of the operation target for each of the plurality of operation targets. The CPU 101 and the controller 105 cooperate to function as the detection unit 302.

  The operation state is a state such as whether or not the operation target (button or key) has been pressed, or whether or not the operation target (switch) has been moved. In this embodiment, the operation target (region 202A, 202B, 202C, 202D) whether or not the position of the center of gravity of the load is included, or some specific numerical values indicating the magnitude of the load.

  The CPU 101 acquires the magnitude of the load applied to each load sensor at a predetermined periodic timing such as a vertical synchronization interrupt (VSYNC) and stores the detection result in the RAM 103.

  When it is detected that a plurality of operation targets have been operated, the estimation unit 303 tries to perform the next operation based on the order of the detected operations and the patterns stored in the pattern storage unit 301. Estimate the operation target. The CPU 101 functions as the estimation unit 303.

  Here, when it is detected that a plurality of operation targets have been operated, specifically, for example, two or more of the four regions 202A to 202D are followed by the center of gravity of the load within the reference time. This is when the position is detected.

  This reference time may be set in advance, for example, 0.5 seconds, or may be calculated by the CPU 101 each time based on the history stored in the RAM 103. In the present embodiment, the reference time is fixed to a predetermined value, but a mode in which the CPU 101 changes the reference time each time will be described in another embodiment described later.

  The action of the player, for example, the action of turning the waist, is not a momentary action, but is usually performed gradually with the passage of time. However, even if the second operation object is operated at the second time after the first operation object is operated at the first time, if the time interval between these operations is very long These two operations are not a series of operations, but are likely to be operations performed intentionally separately. For this reason, it is desirable to set an appropriate reference time in order to determine whether or not a plurality of operations by the player is a series.

  Hereinafter, the estimation process by the estimation unit 303 will be described with some specific examples.

<Specific example of estimation process 1>
After it is detected that the center of gravity of the load is within the region 202A, it is detected that the center of gravity of the load is within the region 202B within a predetermined reference time, and further, the center of gravity of the load is detected within the predetermined reference time. When it is detected that the position is within the region 202C, the order of the detected operations is A for the first, B for the second, C for the third.
In the following description, the order of operations detected by the detection unit 302 is expressed as “[A, B, C]” using the symbol [].

  The CPU 101 compares the detected order [A, B, C] with the patterns stored in the pattern storage unit 301 illustrated in FIG. 4, and detects the detected order [A, B, C]. The similarity with each pattern stored in the pattern storage unit 301 is calculated.

The detected order [A, B, C] is similar to the fact that the fourth operation “D” is missing when compared with the pattern {A, B, C, D} of item No. 1 of group R. The degree is 75%.
Further, the detected order [A, B, C] is completely coincident with the pattern {A, B, C} of the item number 2 of the group R, and the degree of similarity is 100%.
Further, the detected order [A, B, C] is similar to the pattern {A, C, D} of item number 3 of group R because the second and third operations are different. Is 33.3%.
Further, since the detected order [A, B, C] is different from the pattern {B, C, D} of the item number 4 of the group R, all the operations are different, so the similarity is 0%.
However, since a part [B, C] of the detected order [A, B, C] and a part {B, C, D} of the pattern {B, C, D} of the item number 4 of the group R match, The concept of circular arrangement may be adopted, and the similarity may be 66.7%.

  Similarly, the CPU 101 also calculates the degree of similarity between the detected order [A, B, C] and the patterns belonging to other groups such as the group L.

The CPU 101 obtains a pattern having the maximum calculated similarity. In the above case, the pattern with the highest similarity is the pattern {A, B, C} of item number 2 of the group R.
Therefore, the CPU 101 estimates that the movement corresponding to the group R “rotate the hips clockwise” was performed by the player. Then, based on the pattern {A, B, C, D} of item number 1 having the largest number of operation targets designated in the same group, the CPU 101 determines that the operation target that the player intends to operate next is “ D ”. The CPU 101 can estimate the operation target that the player currently playing is about to operate next.

  Note that the CPU 101 may calculate the degree of similarity by other methods, and the calculation formula of the degree of similarity is not limited by the present invention.

<Specific example of estimation process 2>
After it is detected that the center of gravity of the load is within the region 202A, it is detected that the center of gravity of the load is within the region 202B within a predetermined reference time, and further, the center of gravity of the load is detected within the predetermined reference time. When it is detected that the position is within the region 202D, the detected operation order is [A, B, D].

  The CPU 101 compares the detected order [A, B, D] with the pattern stored in the pattern storage unit 301 illustrated in FIG. 4, and detects the detected order [A, B, D]. The similarity with each pattern stored in the pattern storage unit 301 is calculated.

The detected order [A, B, D] is similar because the third operation “C” is missing when compared with the pattern {A, B, C, D} of item No. 1 of group R. The degree is 75%.
Further, the detected order [A, B, D] is different in the third operation from the pattern {A, B, C} of the item number 2 of the group R. Therefore, the similarity is 66.7. %.
Further, the detected order [A, B, D] is different in the second operation from the pattern {A, C, D} of the item number 3 of the group R. Therefore, the similarity is 66.7. %.
Further, the detected order [A, B, D] is similar to the pattern {B, C, D} of the item No. 4 in the group R because the first and second operations are different. Is 33.3%.

  Similarly, the CPU 101 also calculates the degree of similarity between the detected order [A, B, C] and the patterns belonging to other groups such as the group L.

The CPU 101 obtains a pattern having the maximum calculated similarity. In the above case, the pattern with the highest similarity is the pattern No. 1 of group R {A, B, C, D}.
Therefore, the CPU 101 estimates that the player's movement corresponding to the group R has been “rotated clockwise”. Then, the CPU 101 determines that the player is next to “B” and “D” based on the pattern No. 1 {A, B, C, D} having the largest number of operation targets specified in the same group. It is estimated that the operation target to be operated before "" is "C". The CPU 101 can estimate an operation target that the player has attempted to operate in the past.

  For example, even if the player rotates his / her hip clockwise in the order of A, B, C, D, the detection result is {A, B, D}, etc. due to the detection accuracy of the load sensor and the influence of noise, etc. You may end up missing. However, according to this estimation process, the CPU 101 can appropriately estimate the detection result that has been lost.

<Specific example 3 of estimation processing>
When it is detected that the center of gravity position of the load is within the region 202C within a predetermined reference time after it is detected that the center of gravity position of the load is within the region 202D, the order of the detected operations is [ D, C].

  The CPU 101 compares the detected order [D, C] with each pattern stored in the pattern storage unit 301 illustrated in FIG. 4, and detects the detected order [D, C] and the pattern storage unit. The similarity with each pattern stored in 301 is calculated.

  Specifically, first, the CPU 101 extracts a pattern including the detected order [D, C] from all patterns stored in the pattern storage unit 301. Here, the CPU 101 extracts three patterns of item numbers 1, 2, and 3 of the group L.

Of the three extracted patterns, in the two items Nos. 1 and 2 of the group L, the operation “B” is designated after the operation “C”. On the other hand, in item number 3 of group L, operation “A” is designated after operation “C”.
Therefore, the CPU 101 detects that the operation target that will be detected next to the detected order [D, C] is “B” at a rate of 2/3 and “A” at a rate of 1/3. It is estimated that.
As in this example, the CPU 101 can also estimate without calculating a specific parameter of similarity.

  After making the estimation as shown in the above specific example, the CPU 101 proceeds with the game based on the estimation result.

Next, the content of the game performed on the game apparatus 300 will be described.
FIG. 5 is a configuration example of a game screen 500 performed in the game apparatus 300 of the present embodiment. On the screen 500, stationary marks 501 to 504 drawn at fixed positions and a step position indication mark 510 whose drawing position moves with time (in the figure, four types 510A, 510B, 510C, 510D) And a hip roll instruction mark 520, a gauge 530 representing the player's score, a hip roll determination ring 540 representing a detection result by the detection unit 302 or an estimation result by the estimation unit 303, and other background images.

  In this game, music is played by the game device 300. Players can dance to the music to be played by inputting instructions in accordance with instruction marks called footsteps (hereinafter also referred to as “tasks”).

  The step position instruction mark 510 and the hip roll instruction mark 520 are scroll-displayed in accordance with the music to be played. The step position indication mark 510 has one of the up, down, left, and right arrows corresponding to the mat buttons 251 to 254.

  The stationary marks 501 to 504 are marks that indicate the timing (hereinafter also referred to as “task time”) at which the player should press the buttons 251 to 254, respectively. On the stationary marks 501 to 504, an image of one of the up, down, left and right arrows is drawn.

  The step position indication mark 510 moves in accordance with the music playback speed toward the position where the stationary marks 501 to 504 are drawn. When the stepping position instruction mark 510 moves to the same position as the stationary marks 501 to 504, when the player presses any of the buttons 251 to 254 corresponding to the directions of the arrows drawn on the stationary marks 501 to 504, the player's A predetermined score is added to the score, or the value (dance meter) indicated by the gauge 530 is increased.

  When the player achieves a predetermined task at a task time associated in advance, the CPU 101 increases the value indicated by the gauge 530 or increases the score, and evaluates that the game score is excellent. Further, the CPU 101 evaluates that the game results are better as the time when the task is achieved is closer to the task time.

  For example, when the step position indication mark 510 has moved to a position that overlaps one of the stationary marks 501 to 504, a button corresponding to the arrow indicated by the moved step position indication mark 510 (any one of the buttons 251 to 254). When the player presses with one foot, it is possible to take an exemplary dance step that matches the music being played.

Further, when the position of the center of gravity detected by the load sensor of the controller 105 moves as shown by the pattern included in the group R shown in FIG. 4, the CPU 101 determines that the player has turned his / her hip clockwise. .
Further, when the center of gravity detected by the load sensor moves as shown by the pattern included in the group L shown in FIG. 4, the CPU 101 determines that the player has turned his back counterclockwise.

  When the CPU 101 determines that the player has performed an action of turning his / her hip on the controller 105 when the hip roll instruction mark 520 reaches the determination line 550, a predetermined score is added to the score of the player, The value (dance meter) indicated by 530 may increase.

  In the present embodiment, only one type of hip roll instruction mark 520 is displayed at a predetermined position on the screen 500, but the CPU 101 is the first type of hip roll instruction mark indicating that hip roll should be performed counterclockwise. And a second type of hip roll instruction mark indicating that the hip roll should be performed clockwise, may be displayed separately. Then, the CPU 101 may determine the results separately for the game task represented by the first type hip roll mark and the game task represented by the second type hip roll mark.

  Further, the CPU 101 may display a hip roll instruction mark that distinguishes the number of rotations on the screen instead of or in addition to the rotation direction.

  Next, the game process executed by each unit described above will be described with reference to the flowchart of FIG.

  First, the CPU 101 acquires the operation state of each operation target (area 202A to 202D), and stores the acquired operation state in the RAM 103 (step S601). The CPU 101 stores a history of operation states acquired a predetermined number of times in the RAM 103.

  The CPU 101 refers to the history stored in the RAM 103 and determines whether or not a plurality of operation targets have been operated by the player (step S602). In the present embodiment, the CPU 101 determines whether or not two or more of the four areas 202A, 202B, 202C, and 202D have been operated within a predetermined reference time.

In general,
N: Total number of operation targets. An integer greater than or equal to 2.
L: First threshold number. An integer of 2 or more and M or less.
M: Second threshold number. An integer from L to N.
In other words, the CPU 101 determines whether L or more and M or less operation objects among the N operation objects are operated.

  The CPU 101 calculates a time interval from the time when a certain operation target is operated to the time when another operation target is operated next. For a history in which the calculated time interval is longer than the reference time, step S602 is performed. Not subject to discrimination in That is, even when the player operates a plurality of operation targets, if the time interval is longer than the reference time, these operations are not treated as a series of operations by the player, but are treated as individual operations.

  When it is determined that a plurality of operation targets are not operated (as a series of flows) (step S602; NO), the CPU 101 proceeds to a process of step S605 described later. On the other hand, when it is determined that a plurality of operation objects have been operated (as a series of flows) (step S602; YES), the CPU 101 determines the order of the detected operation objects, the pattern stored in the pattern storage unit 301, and Are compared (step S603).

  Then, the CPU 101 estimates an operation target to be operated next by the player based on the comparison result in step S603 by the estimation method as described above (step S604).

  For example, when the CPU 101 determines that two operation objects “X” and “Y” in the four areas 202A, 202B, 202C, and 202D are operated, the detected order [X, Y], Based on the pattern stored in the pattern storage unit 301, the operation target “P” whose operation is to be detected third is estimated.

  For example, when the CPU 101 determines that three operation objects “X”, “Y”, and “Z” in the four areas 202A, 202B, 202C, and 202D are operated, the detected order [X, Y, Z] and the pattern stored in the pattern storage unit 301 are used to estimate which operation target “Q” the operation will be detected fourth.

For example, when the CPU 101 determines that three operation objects “X”, “Y”, and “Z” in the four areas 202A, 202B, 202C, and 202D are operated, the detected order [X, Y, Z] and the pattern stored in the pattern storage unit 301, the player wanted to operate between the first detected operation and the second detected operation. It is estimated which operation target “R” will be.
Alternatively, the CPU 101 estimates which operation target “S” the player would have intended to operate between the second detected operation and the third detected operation. To do.

  Next, the CPU 101 proceeds with the game using the estimation result in step S604 (step S605).

  The method of using the estimation result is not limited by the present invention, but several examples are given below.

<Use of estimation result 1>
Based on the detected order [X, Y], when an operation target that will be detected next (third) is estimated:
The CPU 101 presumes that the player has started a motion of turning his / her waist on the platform 201. Then, the CPU 101 displays a message such as “It's in good condition! Turn it more!” On the monitor or outputs it from the speaker by voice. Accordingly, the game apparatus 300 can appropriately provide game advice, hints, and the like to the player.

<Use of estimation results # 2>
Based on the detected order [X, Y, Z], when an operation target that the player would have intended to operate was estimated between X and Y or between Y and Z :
The CPU 101 estimates that the player has performed a motion of turning his / her hips on the mounting table 201. Then, the CPU 101 displays a message for evaluating the grade such as “GREAT!” On the monitor or outputs the message from the speaker. Thereby, even if the operation to the operation target by the player cannot be completely detected, the game apparatus 300 can appropriately guess the action taken by the player and advance the game.
Further, even if the CPU 101 does not clear the problem of turning around unless all operations are originally detected in the order of [X, Y, Z, W], it does not meet all but some degree. If so, it may be considered that the task has been cleared, and the game may be advanced by adding a score to the player or increasing the value indicated by the gauge 530.
For example, a beginner mode and an advanced player mode are prepared for the game. In the beginner mode, the difficulty level is adjusted by determining the player's performance using the estimation result obtained by the estimation unit 303. It can be used properly, such as judging the player's grade without performing.

<Use of estimation results # 3>
The CPU 101 specifies a pattern having a high similarity to the detected order from the patterns stored in the pattern storage unit 301, and specifies a motion corresponding to a group into which the specified pattern is classified. For example, when the pattern definition shown in FIG. 4 is used, it is determined whether the identified pattern belongs to the group R corresponding to clockwise rotation or the group L corresponding to counterclockwise rotation.
Then, if the specified pattern belongs to the group R, the CPU 101 displays the hip roll determination ring 540 with an animation showing clockwise rotation. On the other hand, if the specified pattern belongs to the group L, the hip roll determination ring 540 is displayed with an animation showing a counterclockwise rotation. Thereby, the game apparatus 300 can perform an effect that matches the movement of the player.

  Returning to FIG. 6, the CPU 101 determines whether or not to end the game (step S606). For example, the CPU 101 determines that the game is to be ended when the value indicated by the gauge 530 is less than or equal to a predetermined value, and otherwise determines that the game is to be continued.

  When it is determined that the game is not ended (step S606; NO), the CPU 101 returns to the process of step S601. On the other hand, when it is determined that the game is to be ended (step S606; YES), the CPU 101 ends the game process.

  According to the present embodiment, the game apparatus 300 can appropriately estimate the player's movement from the operation state of the operation target, and advance the game in accordance with the player's movement.

(Embodiment 2)
Next, other embodiments of the present invention will be described. In the present embodiment, the detection result by the detection unit 302 and the estimation result by the estimation unit 303 are displayed on the monitor and presented to the player in an easy-to-understand manner.

  FIG. 7 is a diagram illustrating a functional configuration of the game apparatus 300 according to the present embodiment. The game device 300 further includes a display unit 701.

  When no operation is detected within the reference time after the estimation by the estimation unit 303 is performed, the display unit 701 displays an image representing the next operation target estimated by the estimation unit 303. Further, when any operation is detected within the reference time after the estimation by the estimation unit 303 is performed, the display unit 701 displays an image representing the operation target detected by the detection unit 302. The CPU 101 and the image processing unit 108 cooperate to function as the display unit 701.

  In the present embodiment, this reference time is a value determined at least before the estimation by the estimation unit 303 is started. Typically, the reference time is determined using real-world time that is timed by a real time clock (RTC). The reference time may be determined by the number of times of VSYNC.

  Alternatively, the reference time may be determined using elapsed time in the game. For example, the reference time may be determined by the number of beats of music to be played, the number of consecutive game tasks, and the like.

  When the load is detected by the load sensor of the controller 105 and the center of gravity position of the detected load is included in any of the regions 202A, 202B, 202C, 202D, the CPU 101 controls the image processing unit 108 to control the center of gravity position. An image associated with an area including is displayed on the monitor.

8A to 8D are diagrams showing the hip roll determination ring 540 in FIG. 5 in a simplified manner.
The hip roll determination ring 540 includes an image 802A associated with the area 202A of the controller 105, an image 802B associated with the area 202B of the controller 105, an image 802C associated with the area 202C of the controller 105, and the controller 105 And an image 802D associated with the region 202D.

  When a load is detected by the load sensor, the CPU 101 controls the image processing unit 108 to display an image corresponding to a region including the detected barycentric position in the images 802A to 802D from other images. Is also highlighted relatively.

FIG. 8A shows a hip roll determination ring 540 in which an image 802A associated with the region 202A is emphasized.
FIG. 8B shows a hip roll determination ring 540 that emphasizes the image 802B associated with the region 202B.
FIG. 8C illustrates a hip roll determination ring 540 in which an image 802C associated with the region 202C is emphasized.
FIG. 8D shows a hip roll determination ring 540 in which an image 802D associated with the region 202D is emphasized.

  The CPU 101 changes and displays the color (hue, saturation, brightness), shape, size, design, etc. of part or all of the hip roll determination ring 540 according to the detection result by the load sensor.

There are various variations in the way of emphasis.
The CPU 101 may display an image corresponding to the area including the detected barycentric position of the load more brightly (with higher brightness) than the other areas.

  In addition, the CPU 101 may blink and display an image corresponding to a region including the detected gravity center position of the load, and may display other regions without blinking.

  Further, the CPU 101 may display an image corresponding to a region including the detected gravity center position of the load, and may not display other regions.

  For example, when the detected order is [A, B, C, D], the display of the hip roll determination ring 540 is as shown in FIG. 8 (a) → FIG. 8 (b) → FIG. 8 (c) → FIG. d) in order. In other words, it looks as if the hip roll determination ring 540 is also rotating clockwise from the player who has turned his back clockwise. Similarly, the hip roll determination ring 540 looks as if it is rotating counterclockwise from the player who turns his / her hip counterclockwise. Accordingly, a game effect that matches the movement of the player is performed.

  Further, the CPU 101 changes the display of the hip roll determination ring 540 according to the estimation result based on the pattern stored in the pattern storage unit 301. The CPU 101 controls the image processing unit 108 to display the image corresponding to the estimated region among the images 802A to 802D with relatively high emphasis.

  For example, when the detected order is [A, B, C], the operation target to be operated next is estimated to be “D”, and the next operation is not detected within the subsequent reference time, the hip roll The display of the judgment ring 540 changes in order as shown in FIG. 8A → FIG. 8B → FIG. 8C → FIG. 8D. That is, to the player who is considered to have turned the hips clockwise, the hip roll determination ring 540 appears to be rotating clockwise. Similarly, to a player who is considered to have turned his / her hip counterclockwise, it appears that the hip roll determination ring 540 is also rotating counterclockwise. Therefore, a game effect that is presumed to match the movement of the player is performed.

  When the next operation is detected within the reference time, the CPU 101 relatively emphasizes and displays an image corresponding to a region including the detected gravity center position of the load among the images 802A to 802D. Shall. That is, for the display of the hip roll determination ring 540, the actually detected detection result is given priority over the estimation result.

  The CPU 101 may change the display of the hip roll determination ring 540 according to the direction in which it is estimated that the player has turned his / her hip.

  FIGS. 9A to 9D are diagrams showing another example of the hip roll determination ring 540. FIG. 9A to 9D, the images 902A to 902D are designed so that the player can easily recognize the direction of rotation. In this example, a picture of “arrow” is drawn.

  For example, it is estimated that the detected order is [A, B, C], and the operation target that the player intends to operate next is “D”, that is, the player is turning clockwise. Consider the case.

When it is detected that “A” is operated first, the CPU 101 immediately displays the hip roll determination ring 540 in which only the image 902A is emphasized as shown in FIG. 9A. By drawing an arrow indicating the direction of rotation in the image 902A, the image 902A is relatively emphasized compared to the other images 902B, 902C, and 902D.
When it is detected that “B” is operated for the second time, the CPU 101 immediately displays the hip roll determination ring 540 in which only the image 902B is emphasized as shown in FIG. 9B. By drawing an arrow indicating the direction of rotation in the image 902B, the image 902B is relatively emphasized compared to the other images 902A, 902C, and 902D.
When it is detected that “C” is operated for the third time, the CPU 101 immediately displays the hip roll determination ring 540 in which only the image 902C is emphasized as shown in FIG. 9C. By drawing an arrow indicating the direction of rotation in the image 902C, the image 902C is relatively emphasized compared to the other images 902A, 902B, and 902D.

  The CPU 101 compares the detected operation sequence [A, B, C] with each pattern stored in the pattern storage unit 301 as shown in FIG. In the case of FIG. 4, the item No. 1 pattern of group R) is selected. The CPU 101 presumes that the player is moving corresponding to the group R, that is, the player is turning clockwise.

  Then, the CPU 101 displays an image 902D illustrated in FIG. 9D instead of the image 802D illustrated in FIG. 8D as an image representing the operation target “D” estimated to be operated next by the player. On the game screen, a hip roll determination ring 540 designed to be associated with right rotation is displayed. As described above, the game apparatus 300 can present the detection result or the estimation result to the player in more detail.

  The images 902A to 902D representing the hip roll determination ring 540 illustrated in FIGS. 9A to 9D are stored in the external memory 106 in advance. After performing the estimation process, the CPU 101 reads out the images 902A to 902D as appropriate and displays them on the game screen.

  FIGS. 9A to 9D show a hip roll determination ring 540 used when it is estimated that the player has turned his / her hip clockwise. A hip roll determination ring 540 having a design reminiscent of the surroundings is displayed on the screen. It is also assumed that a hip roll determination ring 540 used when it is estimated that the player has turned his / her hip counterclockwise is also stored in the external memory 106 in advance.

  According to this embodiment, the player can clearly and intuitively recognize the load detection result or estimation result. Further, the game device 300 can produce a game suitable for the player or a game that is presumed to be suitable for the player, thereby improving the interest of the game.

  In the above description, the CPU 101 changes the display of the hip roll determination ring 540 according to the load detection result or the estimation result, but an embodiment in which the image design, the image display position, and the like are appropriately changed is adopted. It is possible.

  Note that the CPU 101 desirably displays the images 902A to 902D associated with the areas 202A to 202D so as to match the positional relationship of the areas 202A to 202D.

(Embodiment 3)
Next, other embodiments of the present invention will be described. In the present embodiment, the game apparatus 300 can appropriately change the above-described reference time.

  FIG. 10 is a diagram illustrating a functional configuration of the game apparatus 300 according to the present embodiment. The game device 300 further includes a calculation unit 1001.

  The calculation unit 1001 calculates the above-described reference time based on the operation time interval detected by the detection unit 302. The CPU 101 functions as the calculation unit 1001.

  For example, the detected order is [A, B, C], the time when the first operation “A” is detected is T (A), and the time when the second operation “B” is detected is T ( B) It is assumed that the time when the third operation “C” is detected is T (C).

  At this time, the CPU 101 determines the elapsed time T (BA) from time T (A) to time T (B) and the elapsed time T (CB) from time T (B) to time T (C). ) And the time when the operation target X to be operated next (fourth) by the player is operated is estimated.

  Specifically, the CPU 101 calculates an average value of the elapsed time T (BA) and the elapsed time (C−B). Then, the CPU 101 estimates that the next operation “X” is detected after the time indicated by the calculated average value has elapsed from the time T (C).

  Alternatively, the CPU 101 detects the next operation “X” after one of the elapsed time T (BA) and the elapsed time T (CB) has elapsed since time T (C). It may be estimated that

  Then, when no operation is detected by the detection unit 302 within the reference time from the time T (C), that is, from the time T (C) to the time calculated from the time T (C), the CPU 101 estimates the next An image representing the operation target is displayed.

  For example, based on the detected order [A, B, C] and each pattern stored in the pattern storage unit 301, it is estimated that the operation target that the player intends to operate next is “D”. In this case, if no operation is detected within the reference time from the time T (C), the CPU 101 monitors an image representing the estimated operation “D” after the reference time calculated from the time T (C). To display.

  Note that if any operation is detected within the reference time from the time T (C), the CPU 101 displays an image representing the detected operation at the detected time instead of displaying the estimation result on the monitor. Display on the monitor.

Here, an example has been described in which the reference time is calculated based on the detected time intervals of the three operations. However, the number of operations used to calculate the reference time is not limited to three.
If using a general expression, the CPU 101 estimates the time at which the (N + 1) th operation will be detected based on the detected N operations (N is an integer equal to or greater than 2).

  The CPU 101 calculates a statistical parameter such as an average value, a maximum value, a minimum value, a deviation, and a variance of the time intervals between the N operations, and the time at which the (N + 1) th operation will be detected. Can be estimated.

  According to the present embodiment, the game apparatus 300 can appropriately estimate the next operation in accordance with the action performed by the player. For example, the player may have a habit of turning his / her hips, but the game apparatus 300 can estimate the next operation in consideration of the habit of the player.

(Embodiment 4)
Next, other embodiments of the present invention will be described. In the present embodiment, the history of operations performed by the player is stored by the game device 300 and used for estimation processing.

  FIG. 11 is a diagram illustrating a functional configuration of the game apparatus 300 according to the present embodiment. The game device 300 further includes a history storage unit 1101.

  The history storage unit 1101 stores information indicating the history of operations detected by the detection unit 302. The external memory 106 or the RAM 103 functions as the history storage unit 1101.

  More specifically, the CPU 101 adds and stores information indicating the magnitude of the load detected by the load sensor to the external memory 106 or the RAM 103 as a history of the operation order.

  Alternatively, the CPU 101 may store the most recent predetermined number of pieces of information indicating the magnitude of the load detected by the load sensor in the external memory 106 or the RAM 103.

  Further, the CPU 101 may store the magnitude of the load detected by the load sensor in the external memory 106 or the RAM 103 in association with the detected time.

  The CPU 101 may store the magnitude of the load detected by the load sensor in the external memory 106 or the RAM 103 in association with player identification information (for example, a player name). In this case, the player inputs or selects a player name or the like using the controller 105 or the like, and the CPU 101 may store the detection result in association with the player name indicated by the input result or the selection result.

  Based on the history stored in the history storage unit 1101, the estimation unit 303 estimates an operation target that the player intends to operate next.

  Specifically, when performing the above estimation process, the CPU 101 extracts an order similar to the order detected this time from the history stored in the history storage unit 1101. Then, the CPU 101 estimates the operation target that the player intends to operate next from the extracted history. Thereby, the game apparatus 300 can perform suitable estimation according to the past performance of the player.

  Alternatively, when performing the above estimation process, the CPU 101 extracts a history associated with the player who is currently playing the game from the history stored in the history storage unit 1101. Then, the CPU 101 estimates the operation target that the player intends to operate next from the extracted history. Thereby, even in a situation where a plurality of players use the same game apparatus 300, the game apparatus 300 can perform estimation suitable for the player based on the history corresponding to the player who is currently playing. For example, when the player turns off the power of the game apparatus 300 after playing and starts playing the game again the next day, the game apparatus 300 can make an estimation suitable for the player using the history of yesterday.

(Embodiment 5)
Next, other embodiments of the present invention will be described. In the present embodiment, the region occupied by the operation target includes a portion that performs the above estimation processing when the center of gravity position of the load is included, and a portion that does not perform the above estimation processing.

  FIG. 12 is a diagram simply showing the mounting table 201 of the controller 105. The surface of the mounting table 201 is divided into four regions (regions 202A, 202B, 202C, 202D).

  Further, the entire four regions are divided into an estimation target region 1200 and other regions. The estimation target area 1200 is set near the boundary between adjacent operation targets. The shape, number, arrangement method, and the like of the estimation target area 1200 are not limited by the present invention.

  A predetermined two-dimensional coordinate system is defined in advance in the areas 202A to 202D. The estimation target area 1200 and the gravity center position are represented by coordinate values in this coordinate system.

When the center of gravity position of the load is included in the estimation target area 1200, the player's weight shift is not sufficient, and it is the result of the player's intention to move the center of gravity, or due to the surrounding vibration or the movement of the player's movement It may not be clear whether the center of gravity is the result of accidental movement.
Therefore, the game apparatus 300 performs the above estimation process to estimate the player's action when the estimation target area 1200 includes the load center of gravity position, and the load center of gravity position is present in a portion other than the estimation target area 1200. If included, the detection result by the load sensor is used as it is for the progress of the game without performing the above-described estimation process.

  In the present embodiment, the detected order and the pattern stored in the pattern storage unit 301 are not always compared. Therefore, the CPU 101 can not only properly estimate the player's movement but proceed with the game. The load of processing to be performed can be reduced.

  The present invention is not limited to the above-described embodiments, and various modifications and applications are possible. Moreover, it is also possible to freely combine the constituent elements of the above-described embodiments.

  In each of the above embodiments, only one operation target to be operated next by the player is estimated. However, it may be configured to estimate two or more operation targets to be operated by the player from the next time on. Good.

  In each of the above embodiments, the movement of the player is estimated from the state of the load applied to the balance board type controller 105. However, in other types of controllers such as a touch pad type, a grip type, and a mat type, Based on the order of pressing, it is also possible to estimate the operation target that the player intends to operate next.

  In each of the above embodiments, the arrangement of the operation target (the arrangement of the load sensor) in the controller 105 and the arrangement of the images 802A to 802D (or 902A to 902D) in the hip roll determination ring 540 are made to match. It does not necessarily need to match.

  FIG. 13 is a diagram illustrating a modification of the hip roll determination ring 540. An image 1302A is associated with the area 202A of the controller 105, an image 1302B is associated with the area 202B of the controller 105, an image 1302C is associated with the area 202C of the controller 105, and an image is associated with the area 202D of the controller 105. 1302D is associated. As shown in this figure, even if the arrangement of the operation target and the arrangement of the images 1302A to 1302D do not coincide with each other, it is determined whether or not the player has turned the hip, whether the hip is rotated clockwise or counterclockwise. The game situation such as can be presented to the player in an easy-to-understand manner.

  A program for operating a computer as all or part of the game apparatus 300 is stored in a computer-readable recording medium such as a memory card, CD-ROM, DVD, or MO (Magneto Optical disk) and distributed. This may be installed in another computer and operated as the above-described means, or the above-described steps may be executed.

  Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.

  As described above, according to the present invention, it is possible to provide a game device, a game processing method, and a program suitable for estimating the movement of the player according to the operation state of the operation target.
