Description

  In the present invention, when a mouse or a small display held by a hand is moved to scroll display contents, a cursor is moved, or a menu focus is moved, a plurality of vibration generators can be moved to a user's finger. The present invention relates to a tactile stimulus presentation method that applies vibration and allows a user to clearly understand the amount and direction of scrolling and cursor movement through the vibration pattern.

  Recent computers use an operation system based on a GUI (graphical user interface), such as Microsoft Windows (registered trademark), and with a pointing device such as a mouse, the display contents can be scrolled or the cursor can be moved. The user's intention is transmitted to the computer by an operation of moving or moving the focus of the menu. In recent years, GUIs are also used in small information terminals such as mobile phones, and there is a need for a display system suitable for browsing content designed for a large screen of a personal computer with a small display. . The biggest drawback of the GUI is that it imposes an excessive burden on vision, and it is impossible for the visually impaired to operate at all. Also, the work of moving the cursor to the target point while constantly gazing at the display is also accompanied by fatigue. .

  Therefore, a haptic user interface (HUI) has been studied as a new user interface that can be used by visually impaired persons by using tactile sensation for vision and can also reduce the burden on healthy persons. Therefore, the basic is to make it possible to grasp the GUI operation for scrolling the display contents, moving the cursor, and moving the menu focus as much as possible through the sense of touch.

  In addition, as described above, when viewing image content designed for a large display using a small display, it is assumed that the content is virtually stationary to the outside of the display at the back of the display in order to make it easier to grasp the overall image. However, a scrolling method has been proposed in which the part where the content that is virtually stationary changes when the small display is moved like a viewing window has been proposed. It takes time. Therefore, when the small display is moved slowly, the movement amount of the small display and the movement amount of the scroll are associated with each other. However, when the movement is performed quickly, the movement amount of the small display is enlarged to correspond to the movement amount of the scroll. Search efficiency can be improved. However, when the correspondence relationship of the movement amount is changed in this way, the user is confused without being able to grasp the correspondence relationship at that time, and the scroll cannot be controlled as desired.

  In order to cope with the above-described problem, in the present invention, vibration is applied to each of a plurality of fingers of a user holding a mouse or a small display through independent vibration sources. And by changing the timing of vibration generation of each vibration source according to the movement amount, movement speed, movement direction of the focus etc. indicating the highlighted contents in the menu, the contents to be displayed when scrolling, and the focus, etc. The user can grasp the movement amount, the movement speed, and the movement direction through the sense of touch. Alternatively, as is conventionally done, these vibration sources are also used for the purpose of generating vibrations to notify that the cursor or focus has reached the target point on the screen.

Patent documents related to the present invention are shown below.

  First, Patent Documents 1 to 5 relate to a method in which when a small display is held and moved by hand, the movement is detected, and display contents are scrolled based on the amount, speed, acceleration, and direction of the movement. In particular, Patent Document 1 discloses a method of mounting an acceleration sensor on a small display, and scrolling and enlarging / reducing the display image based on the movement of the display body detected by the acceleration sensor. Patent Document 2 discloses a display system that displays a portion of a virtual image content that is fixed on a desk when the small display is moved on a desk and that is visible when the small display is viewed as a small window. Furthermore, in Patent Document 4, it is assumed that there is an object that is virtually stationary in the outside world, and when the small display is moved by hand, the part that should be originally visible at the moving position is displayed, thereby making it easy to understand the whole image. The technique to display is shown. As for the display system that detects the movement of the display itself and scrolls based on the movement, the conventional system has not been put into practical use even though many patents have been filed for a long time. The system lacks tactile cues, and it is difficult to control scrolling while confirming the movement of the image by visual observation alone.

  Next, Patent Documents 6 to 9 relate to a method in which a plurality of vibration sources provide various information to the user by applying vibration having a time difference or a phase difference to the user's tactile sense. In Patent Document 6, a device is provided that generates a standing wave or a traveling wave of vibration on the surface of the operation unit and transmits surface information such as a slipperiness and surface roughness to an operator who touches the surface. Patent Document 7 shows a method of transmitting information to a driver in a vehicle through vibration by controlling the drive timing and location of the vibrator, the number of vibrators to be driven, and the like in accordance with the content of information to be presented. . Further, in Patent Document 8, various tactile sensations are generated by arranging a plurality of stimulation sources that are independently driven on the skin surface and controlling the phase difference of the vibrations of the adjacent vibration sources. Shows how. Patent Document 9 shows a method in which a user is made to feel various inertial forces by mounting two vibration motors in a game controller and making a difference in the rotation timing of the eccentric weight or changing the strength. ing. In the above Patent Documents 6, 8, and 9, the phase difference of the vibration waveform (or the rotational movement of the eccentric weight) itself is used as the phase difference, and the change in tactile sensation that can be created by such a phase difference is used. Therefore, it is difficult to clearly transmit the scroll related to the GUI, the moving speed of the cursor, etc. by such a tactile sensation. In Patent Document 7, a time difference is given to the timing of driving the vibration source, but the vibration generated by each vibration source is used to be perceived as a separate stimulus, and the time when the two vibration sources are close to each other is used. It does not use the phenomenon of feeling the movement of the vibration source when it is vibrated with a time difference.

  The present invention has been devised in view of the above situation, and by generating vibrations with relatively high frequency in a short time in a concentrated manner, a mass of vibration waveforms in which energy is concentrated in a short time (hereinafter referred to as this A block of vibration waveforms is called a vibration pulse), and the time difference of the vibration pulse is used instead of the phase difference of the vibration waveform itself used in the above-described prior art, and the perception of the movement of the vibration source in the user's tactile sense It is an object of the present invention to provide a tactile stimulus presentation method capable of grasping, through tactile sense, GUI operations for scrolling display contents, moving a cursor, and moving a menu focus.

  An object of the present invention is to improve the operability of a content viewer that scrolls the display content of a small display based on the movement of a mouse or a main body itself equipped with a small display. Therefore, when holding the mouse and the content viewer, paying attention to the fact that a plurality of fingers come into contact with the side surfaces, vibration sources that are independently driven are arranged at positions where these fingers come into contact. Then, the user feels that the vibration source is moving between the fingertips by stimulating the tactile sensation of the user's finger with an appropriate time difference between the vibration pulses generated by these vibration sources.

  This is based on the assumption that, in visual sense, the illusion phenomenon in which two images presented with an appropriate time difference are felt as if there is movement, as known through the principle of animation, also occurs in tactile sensation. .

  However, such an illusion cannot be felt even if there is a time difference (phase difference) between the two waveforms at the level of the vibration waveform. Since the time difference in the phase difference level of such a waveform is a short time difference that is less than the perceptual limit at which a person feels movement, the person cannot feel it as movement.

Therefore, in the present invention, vibration pulses are applied to the two fingers of the user with an appropriate time difference when a person feels movement. The vibration pulse applies energy to the finger in a short period when high-frequency vibration is short, so the user feels as if something has hit the finger and the finger, but the touch is a short time difference from finger to finger. When the user moves, the user feels as if something hitting the finger has moved to another finger instantly.
Although the specific frequency of the vibration pulse depends on the weight and size of the resonator, for example, a vibration source for generating a vibration pulse that has been commercialized by Alps Electric Co., Ltd. ) Etc., the frequency of the vibration pulse is preferably about 2 to 30 times, the period of the vibration waveform is preferably about 1 to 10 milliseconds, and the duration is preferably about 2 to 300 milliseconds.

  In this way, by using the feeling related to the movement created by the vibration pulse, in the basic GUI operations such as scrolling the display contents, moving the cursor, and moving the menu focus, the scroll amount, the cursor, The user can grasp through the sense of touch the amount of movement of the focus, these speeds, and even whether or not the target has been reached. The specific means is as follows.

  First, this tactile stimulus presentation method is mounted on a device that is held by hand and is operated by moving it back and forth and left and right. Based on the direction and amount or speed of movement of this device, it is used with a display system that scrolls the display content of the display provided on this device body or a separately installed display, and moves the cursor and focus, The purpose is to support the operation of this display system through the sense of touch. For this purpose, vibration generators that vibrate independently are installed in at least two positions on the side of the device body where the fingers touch, and these vibration generators vibrate intensively in a short period when a drive signal is applied. To generate vibration pulses. Here, the generation timing of the vibration pulse is controlled so that a predetermined time difference is generated in the vibration pulse generated by each vibration generator, and the scroll direction and amount or speed, the cursor, Informs the user of the moving direction and moving amount or moving speed of the focus.

  Here, it is desirable that a vibration pulse is transmitted to each finger independently, and it is necessary to devise a technique for making it difficult for crosstalk to be transmitted to other fingers through the body. Therefore, an insulator that absorbs vibration, a material that becomes a damper, or an elastic body such as a spring is preferably disposed between the vibration generator and the device body. Alternatively, vibration having a phase opposite to that generated by the vibration generator may be generated so that both vibrations cancel each other and no vibration is transmitted to the device body.

  In the GUI, an icon is displayed on the screen, and an operation of specifying the icon with a cursor is performed. At this time, the user has to move the cursor by moving the mouse or the display body to reach the target icon. However, in the conventional GUI, this work must be performed while visually observing the movement of the cursor. He was not allowed to turn his gaze inside. If this work can be grasped as much as possible by tactile sense and visual support can be provided, the operability of the user interface is expected to be greatly improved. In the conventional method of using the vibration, when the cursor has reached the target point, it has only been done to generate and notify the vibration, but in the present invention, a tactile cue is added in the process until the target is reached, We are thinking of supporting the operation from a prior process. To this end, not only generates vibration when the cursor reaches the target icon or crosses the boundary of the target menu item, but also generates an appropriate time difference from multiple vibration generators while the cursor is moving. Depending on the amount or speed of scrolling and the amount or speed of movement of the cursor or focus, the timing and period of vibration pulse generation can be changed and added to the fingertips to make these speeds and directions feel Tell your fingertips. Specifically, the generation order and time difference of vibration pulses between multiple vibration sources are changed according to the direction of movement of the cursor, and added to the finger to create an illusion of movement so that the direction of movement of the cursor can be grasped. To do. Alternatively, the moving speed of the cursor can be grasped by changing the generation period of the vibration pulse. A similar method can be applied when moving the focus or scrolling the display screen.

  In order to notify the moving speed and direction of the cursor and scroll described above, specifically, two vibration generators are installed at positions where two fingers holding the device are in contact with each other, and the first finger is in contact with each other. It is preferable that the first vibration generator and the second vibration generator in contact with the second finger generate vibration pulses as follows. That is, when the device body is moved back and forth, the first vibration generator generates a vibration pulse and the second vibration generator is stopped. When the device body is moved left and right, the first vibration generator is stopped. The second vibration generator generates vibration pulses. In this method, it can be identified whether the movement is left and right or back and forth by saying which of the first vibration generator and the second vibration generator vibrates. In addition, the movement amount and movement speed can be transmitted to the user by the generation period of the vibration pulse. However, since there is no illusion of movement due to the time difference between the vibration pulses generated by the two vibration generators, whether it is the front or back of the front and rear movements, or the left or right of the left and right movements Cannot be identified. In order to improve this problem, it is necessary to add one vibration generator and use the following method.

  When the first vibration generator in contact with the first finger, the second vibration generator in contact with the second finger, and the third vibration generator in contact with the third finger are installed, and the device body is moved back and forth When the first vibration generator and the second vibration generator generate vibration pulses with a minute time difference and the device body is moved left and right, the first vibration generator and the third vibration generator have a minute time difference. To generate vibration pulses. In order to grasp the moving direction through the above-mentioned illusion, the minute time difference described above is set as a time difference suitable for humans to sense the movement, and the generation order of vibration pulses changes depending on the moving direction of the device body. To do.

  In the above method, the first vibration generator is shared when creating the illusion of back-and-forth and left-right movements. If it is possible to design the device so that it can come into contact with another, it is better to introduce another vibration generator and take the following method. That is, the first vibration generator in contact with the first finger, the second vibration generator in contact with the second finger, the third vibration generator in contact with the third finger, and the fourth finger in contact with the fourth finger. When the vibration generator is installed and the device body is moved back and forth, the first vibration generator and the second vibration generator generate vibration pulses with a minute time difference, and when the device body is moved left and right, the third The vibration generator and the fourth vibration generator generate vibration pulses with a minute time difference. These minute time differences are appropriate for humans to illusion of movement, and by changing the generation order of these vibration pulses depending on the movement direction of the device body, the cursor and scroll move from one to the other. So that the user can understand through the illusion.

  In recent GUIs, a mechanism for accelerating the movement of a cursor or scroll during operation is introduced in order to increase the operation efficiency. Moving the mouse long distances to move the cursor far away will make the user tired and time consuming. Therefore, when the mouse is moved slowly, the movement is reflected on the cursor and scroll movement without being amplified. However, when the mouse is moved quickly, the movement of the mouse is amplified and reflected on the cursor and scroll movement. Even when the mouse can only be moved within a narrow range of operation in this way, if the mouse is moved quickly, the cursor and scroll can be moved greatly to reach far targets. However, this mechanism causes great confusion if the user cannot grasp the current amplification degree. Especially in the content viewer with a small display mentioned above, if you continue scrolling without knowing the amplification level, the display size is small and you can not grasp the whole picture, so what part of the content you are looking at now? I don't know.

  In order to support the operation of the GUI in which the acceleration mechanism is introduced as described above, it is preferable that the user can grasp the scroll speed or the cursor or focus speed through the generation period of the vibration pulse. In other words, these speeds and the generation period of vibration pulses are roughly inversely proportional, and if the above amplification factor is high, the generation period of vibration pulses will be shortened. On the contrary, if the amplification factor is low, the generation period of the vibration pulse may be increased so that the vibration pulse is generated only infrequently even if the mouse is moved a lot. By doing so, the user can always grasp the moving speed and moving amount of the cursor and scroll during the operation through the frequency and frequency of occurrence of the vibration pulses while moving the mouse.

  When the mouse or the content viewer is moved obliquely by the above-described method, the vibration pulse for notifying the forward / backward movement and the vibration pulse for notifying the left / right movement are the movement amount components in the respective directions or It is only necessary to generate simultaneously according to the velocity component, but when there are only three vibration generators and the first vibration generator is shared for both notifications, the first vibration generator is generated. It is necessary to synchronize the generation timing of the vibration pulse so that one vibration pulse can be used for both movement amount components. Therefore, as for the movement in the oblique direction, it is possible to generate the vibration pulses representing the respective movements while shifting the movement in the front-rear direction and the movement in the left-right direction alternately (not simultaneously).

  In the present invention, a vibration generator that is in contact with a plurality of fingers holding a mouse and a content viewer is provided for each finger, and the time difference and period of vibration pulses generated by the fingers are appropriately controlled and applied to the finger, thereby allowing the finger to sense The amount, direction, and speed of scrolling, cursor, and focus movements can now be grasped. In this way, tactile information can be used for basic GUI operations, and GUI operability is greatly improved even in a content viewer having a small display.

  FIG. 1 shows an embodiment in which the tactile stimulus presentation method of the present invention is applied to a content viewer (device). 1A is a perspective view, FIG. 1B is a left side view, and FIG. 1C is a right side view. Each side view shows the main internal structure in perspective. In the figure, reference numeral 1 denotes a small display for displaying contents. However, if the display and the functions related thereto are removed, the present invention is implemented in a mouse. This content viewer has the same input function as a mouse, 2 is a left mouse button, 3 is a scroll wheel, 4 is a right mouse button, and 15 is a current optical mouse mainstream motion sensor. It is. This sensor detects a change in the position of the device body in the x-axis direction and the y-axis direction by measuring the movement of the surface of a desk or the like illuminated with light emitted from the bottom of the device.

  The key to the present embodiment is the vibration generator shown in 5, 6 and 7. Here, among the various methods described above, a method in which the number of vibration generators is three is shown. As shown in FIG. 3 later, it is assumed that the vibration generator 5 is in contact with the thumb, the vibration generator 6 is in contact with the ring finger, and the vibration generator 7 is in contact with the middle finger. It doesn't matter. However, in this embodiment, it is assumed that each finger is in contact with the side surface of each vibration generator and the device body is held and operated to move back and forth and right and left. A vibration generator is placed on the side of the device that is easy to touch.

  FIG. 2A shows a top view of the content viewer shown in FIG. Various elements used in a typical GUI are displayed on the display 1 in the figure. When the content viewer main body is moved, the focus 9 (the highlighted item) in the cursor 8 or the menu 10 moves according to the amount and direction of the movement. Alternatively, when scrolling, the content displayed on the screen moves with the movement of the content viewer body. For example, when the content viewer main body is moved in the direction of the arrow 11, the cursor 8, the focus 9, or the display content moves in the same direction as the arrow 11, or in the opposite direction to the arrow 11 depending on the setting. In the case of scrolling, the content displayed on the screen in the reverse direction with respect to the movement of the content viewer body can be easily understood intuitively because it corresponds to the situation in which the outside object is viewed through the viewing window.

  FIG. 2B shows a state in which three vibration generators 5, 6, and 7 are installed inside the content viewer. Between each vibration generator and the content viewer body, springs 12, 13, and 14 acting as dampers, insulators or suspensions are interposed. This makes it difficult for the vibration of each vibration generator to be transmitted to the main body, so that the user can feel each vibration independently without interference. Further, instead of the spring, another vibration generator that vibrates in the opposite phase to the vibration generator may be introduced so as to cancel the vibration.

  FIG. 3 shows how the content viewer of FIG. 1 is held and operated. When held as shown in this figure, the thumb, middle finger, and ring finger come into contact with the side of the main body. Therefore, it is a major point of the present invention to install a vibration generator at the contact position. Since humans have limited tactile abilities and vibrations have a property of diffusing, it is difficult to distinguish and perceive those positions even if vibrations are applied to close positions on the skin. In the present invention, a plurality of vibration sources are in contact with the fingertips of different fingers to apply vibrations so that different vibration sources can be distinguished with sensitive fingertips. As described above, the vibration source is arranged at a position where the finger on the side of the main body hits so that the main body can be held and moved back and forth and right and left while applying a finger so as to feel vibration. In the figure, arrows defining front, rear, left and right reference directions are also shown.

  FIG. 4 is a block diagram of the content viewer 30 including the control circuit 20 according to the present embodiment. Here, the control circuit 20 of the content viewer 30 inputs signals from the mouse left button 2, the right button 4, the scroll wheel 3, and the optical motion detection sensor 15, and converts them into signals for CPU processing. 21, a storage circuit 22 that stores data, an arithmetic circuit 25 that executes arithmetic processing by the CPU, and an output circuit 23 that converts the output signals from the arithmetic circuit 25 into signals for driving the vibration generators 5 to 7 , And a display output circuit 24 for generating a signal for display output on the display 1.

  The storage circuit 22 includes a memory element and stores data necessary for the CPU to perform arithmetic processing. For example, the time difference Δ between vibration pulses, the basic stimulus amount as data for determining the magnitude of vibration of the vibration generators 5 to 7, and data indicating the relationship between the moving acceleration of the content viewer 1 and the magnitude of vibration. A certain acceleration stimulus amount, vibration cycle, and control condition data are stored. The control conditions include, for example, whether the impulse width (duration) is determined as a moving distance or a time, and whether or not stimulation is repeated when a long distance is moved.

  Next, the calculation processing of the content viewer 1 having the above configuration will be described with reference to FIG. The arithmetic circuit 25 inputs signals from the optical motion detection sensor 15, left and right buttons 2 and 4 and scroll wheel 3 via the input circuit 21, and changes in motion (for example, speed change or Start by detecting position change).

Then, the movement direction, movement amount, movement speed, and movement acceleration of the device are calculated from the input signal (S101), the magnitude of the vibration impulse is calculated from the movement acceleration (S102), and the vibration generator opposite to the movement direction is calculated. Is vibrated at the calculated size (S103). The control signal output from the arithmetic circuit 25 is transmitted to the corresponding vibration generator via the output circuit 23.
Then, when Δ time elapses from the vibration start time (“Yes” in S104), the other vibration generator in the moving direction is vibrated with the same magnitude (S105).

Next, the control circuit 25 extracts the stimulation continuation condition from the storage circuit 22 (S106), determines the condition (S107), and if the stimulation continuation condition is a movement amount, the movement amount of the device is a predetermined value. (S108), if it is equal to or greater than a predetermined value, the vibration of the vibration generator in the direction opposite to the moving direction is stopped (S112). On the other hand, if the stimulus continuation condition is time in step S107, it is determined whether or not a predetermined time has elapsed since the vibration generator was turned on (S110). The vibration of the direction vibration generator is stopped (S112).
If Δ time has elapsed after the process of step S112 (“Yes” in S113), the vibration of the vibration generator in the other direction, that is, the moving direction is stopped (S114).

Next, it is determined whether or not the movement is completed based on data such as a movement direction and a movement amount (S115). If the movement is continued ("No" in S115), the stimulus repetition condition of the storage circuit 22 is set. Referring to this condition, if it is ON (“Yes” in S116), it is determined whether or not it has moved a predetermined value or more (S117), and if it has moved a predetermined value or more, step S101. Return to. This again generates a vibration impulse.
On the other hand, if the stimulus repetition condition is OFF in step S116 (“No” in S116), the process ends.

  FIG. 6 shows the waveform of the vibration impulse generated by the above processing. Here, the horizontal axis represents the time axis, and the vertical axis represents the amount of vibration variation (or pressure). Unlike normal vibrations, the vibration impulses concentrate energy at short time intervals, and form a cluster of vibration waveforms localized in time as shown in FIG. FIG. 6B shows a state where two vibration impulses are generated with a time difference. There is a time difference of Δ between the A wave and the B wave. It should be pointed out that this time difference is a time difference between waveform blocks and is different from the phase difference of a normal waveform. The phase difference of the waveform can be distinguished only up to the time difference up to one period of the waveform at the maximum (even if it is larger than this, the difference in the integral multiple of the period cannot be distinguished due to the periodicity of the waveform, and the time difference within one period The time difference defined between the vibration impulses as shown in FIG. 6B can take an arbitrary magnitude, and even if it is increased, the difference can be distinguished. The magnitude of Δ is changed in the range of several tens of milliseconds to several hundreds of milliseconds so as to create an illusion that an object touches and moves from finger to finger. For example, when an A wave is applied to the thumb and a B wave is applied to the ring finger, an illusion that an object hitting the thumb moves and hits the ring finger is generated.

  The present invention is not limited to the above-described embodiments and can be implemented with various modifications. For example, in the above-described embodiment, the display is integrated with the input device as an example of the integrated content viewer.

It is a figure which shows one Example which applied the "tactile stimulus presentation method which supports operation of a display system" of this invention to the content viewer. If the display is removed from this figure, it is an example applied to a mouse. Similar to the mouse, a position detection sensor is provided on the bottom surface to detect the movement of the device body. FIG. 2 is a view of the content viewer of FIG. 1 as viewed from the front, and a display shows a cursor, menu, and focus (highlighted items) that are the basis of a GUI. On the right side (FIG. 2A), an internal structure of an insulator such as a spring for preventing the vibration of the vibration generator from being transmitted to the device body is shown. It is a figure which shows a mode that the content viewer of FIG. 1 is hold | maintained by hand. It is easier to hold the device by holding the side of the device with your thumb, middle finger, and ring finger. You can also operate the buttons and wheels on the device surface with your free index finger. Even if you hold your hand from the back side of the device in the air, it is easy to hold it with your fingers against the side as described above, so install the vibration generator at the position where the fingers on the side touch.
