Description

  The present invention relates to a display device and a computer program for causing the display device to execute.

  Conventionally, a display device having a touch panel function in which a display function and an input function are shared is known. In this type of display device, a touch panel unit is provided on the upper surface of the display unit, and based on the positional correspondence between the pressed position of the operation finger on the touch panel unit and the display component displayed in the display area of the display unit. The display component corresponding to the pressing operation is specified, and the function assigned to the display component is executed.

Patent Documents 1 to 3 disclose a method for detecting the position of the operating finger before a pressing operation is performed on the touch panel unit.
JP-A-6-4214 JP 2005-71246 A JP 2006-285491 A

  However, when the arrangement interval of individual display components is narrow or the display components are displayed small, the display component intended by the operator is selected when selecting the display component displayed on the display area of the display unit. There is a problem that it is recognized that a display component different from the above is pressed. Such a problem becomes more prominent as the size of the display area of the display unit is smaller.

  The present invention has been made in view of such circumstances, and an object thereof is to predict in advance the display components corresponding to the pressing operation before the operator performs the pressing operation on the touch panel unit. Thus, the operability for the operator is improved.

  In order to solve the problem, the first invention provides a display device having a display unit, a control unit, a first touch panel unit, a detection unit, and a storage unit. Here, the display unit includes a display area. The control unit determines a display component to be displayed in the display area as a display target component, and controls the display unit so that the determined display target component is displayed in the display area. The first touch panel unit is disposed above the display unit, detects the position of the pressing operation by the operating finger, and uses the coordinates on the display area corresponding to the pressing operation as the pressed coordinates as a control unit. Output to. The detection unit detects the position of the operation finger on the assumption that the first touch panel unit is pressed in a detection area set above the first touch panel unit, and corresponds to the operation finger in position. The coordinates on the display area are output to the control unit as predicted coordinates. The storage unit stores a predicted coordinate range indicating at least a range on the display area included in the display component in association with each other for each of the plurality of display components. In this case, the control unit searches the storage unit based on the predicted coordinates from the detection unit, thereby causing the display target component associated with the predicted coordinate range including the predicted coordinates to be displayed via the first touch panel unit. It is specified that the pressed operation is predicted to be pressed.

  Here, in the first invention, the detection unit sets a detection area above the display area of the first touch panel unit, and determines the position of the operating finger that passes through the detection area and approaches the first touch panel unit. It is preferable that the sensor is configured to detect. Alternatively, the detection unit is configured by a second touch panel unit that is arranged on the upper surface of the first touch panel unit and has its own surface as a detection area. It is preferable that the detection sensitivity is set to be higher than the detection sensitivity of the touch panel unit.

  In the first invention, it is desirable that the control unit changes the display state of the display target component based on the viewpoint of assisting the pressing operation on the touch panel unit targeting the specified press predicted component.

  Here, the display component includes at least character information, and the control unit changes the display state of the display target component so that the character information included in the press prediction component becomes bolder than before the display state is changed. The display device according to claim 4.

  In addition, the control unit changes the display state of the display target component so as to hide the display target component other than the press predicted component.

  In addition, the control unit changes the display state of the display target component so that the display target components other than the pressed prediction component are less clear than before the display state change.

  In addition, the control unit changes the display state of the display target component so that the pressed prediction component is displayed in an enlarged manner before the display state change.

  In addition, the control unit specifies the display target component included in the predetermined range centered on the press prediction component as the peripheral display component, and the press prediction component and the peripheral display component are displayed in an enlarged manner before the display state change. Next, the display state of the display target component is changed.

  The display target component includes a first display target component that can be operated by the operator and a second display target component that cannot be operated by the operator, and the control unit includes a press prediction component and a press prediction component. The display state of the display target component is changed so that the first display target component other than the display target component is enlarged and displayed as compared to before the display state change.

  In addition, the control unit enlarges the display and changes the display state of the display target component so that the function of the display component is displayed.

  Furthermore, in the first invention, the display device may further include an audio output unit that outputs audio information. In this case, the control unit outputs information describing the function of the press prediction component based on the specified press prediction component via the voice output unit.

  The second invention provides a computer program for causing a display device having a touch panel unit disposed above a display area of a display unit to execute the program. The computer program includes a first step of determining a display component to be displayed in the display area as a display target component, a second step of displaying the determined display target component in the display area, and a first touch panel unit. In the detection area set above the first position, a coordinate on the display area corresponding to the operation finger is obtained as a predicted coordinate from the detection unit that detects the position of the operation finger approaching the first touch panel unit. Step 3 and, for each of a plurality of display components, search for component information associated with at least a predicted coordinate range indicating a range on the display area included in the display component, and associate with the predicted coordinate range including the acquired predicted coordinate A fourth step of specifying that the displayed display target component is a press prediction component for which a press operation via the first touch panel unit is predicted. To.

  Here, the second invention is a fifth device that changes the display state of the display target component based on the viewpoint of assisting the pressing operation to the touch panel unit targeting the press predicted component specified in the fourth step. It is desirable to further include steps.

  According to the present invention, the predicted coordinate range is associated with each display component and stored in the storage unit. Therefore, referring to this storage unit, it is possible to achieve a positional correspondence between the predicted coordinate and the predicted coordinate range, and it is possible to specify the pressed predicted component. Thereby, the display target component that the operator wants to select can be specified before the touch panel unit is pressed. Therefore, since it is before the pressing operation of the touch panel part, that is, before the substantial selection by the operator is performed, various processes can be realized based on this pressing prediction component. It becomes possible to improve the operability for the operator.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of a display device according to an embodiment of the present invention. FIG. 2 is an explanatory diagram schematically showing the appearance of the display device, and some components are omitted. This display device is provided in a facility such as a factory, for example, and displays the operating status and facility information of various devices in the factory and has an input function for centrally controlling the device and equipment. is there.

  The display device mainly includes a display unit 10, a touch panel unit 20, a detection unit 30, a control unit 40, a storage unit 50, and an audio output unit 60.

  The display unit 10 is configured by a known display (display unit) such as a liquid crystal or a CRT, and is controlled by the control unit 40 described later to display various information. The display unit 10 is installed on, for example, a wall surface in a factory, and it is preferable to use a relatively small display in order to make it difficult to receive restrictions on the installation location. The display unit 10 has a display area 11 in which information is substantially displayed. In the display area 11, coordinate information that defines a two-dimensional position on the display area 11 is set in advance. For example, the coordinate information is set as two-dimensional coordinates of a horizontal coordinate (X coordinate) and a vertical coordinate (Y coordinate) with the upper left corner of the display area 11 as the origin.

  The touch panel unit 20 is disposed above the display unit 10, specifically, on the surface thereof so as to cover at least the display area 11. As the touch panel unit 20, a resistive film type analog touch panel or the like can be used. This type of touch panel is generally composed mainly of an upper transparent electrode plate and a lower transparent electrode plate. Each transparent electrode plate has a transparent substrate and a transparent conductive film formed on the transparent substrate, and the upper and lower transparent electrode plates are spaced so that the transparent conductive films face each other. Arranged. When the upper transparent electrode plate is pressed with an operating finger, the touch panel portion 20 having such a configuration is bent at the pressing point, and the transparent conductive films of the upper and lower transparent electrode plates are in contact with each other. . And the coordinate information of this contact point is detected by the measurement of electrical resistance, and this is output to the control part 40 as a pressing coordinate which shows the position of pressing operation. The coordinate information set in the touch panel unit 20 is set in a positional relationship with the coordinate information set in the display area 11 of the display unit 10, and the pressed coordinate is a display corresponding in position to the pressing operation. The coordinates on the area will be shown. Further, when a pressure equal to or higher than the first pressing pressure set as the detection sensitivity is applied, the touch panel unit 20 detects this as a pressing operation. Therefore, when the pressing operation is performed with a pressure smaller than the first pressing pressure, the pressing operation is not detected. The operating finger is directly the operator's own finger, but includes various elements such as an input pen that can operate the touch panel unit 20.

  FIG. 3 is an explanatory diagram illustrating a configuration of the detection unit 30 according to the first embodiment. The detection unit 30 detects the position of the operating finger on the premise that the touch panel unit 20 is pressed in the detection area 33 set above the touch panel unit 20, and is pressed by the operating finger. The predicted coordinates indicating the wax position are output to the control unit 40. In the present embodiment, the detection unit 30 includes a plurality of light emitting units 31 that are arranged in the horizontal direction of the display area 11 and emit detection light (hereinafter referred to as “vertical detection light”) in the vertical direction of the display area 11. A light receiving unit 32 that receives vertical detection light, and a pair of light emitting units that are arranged in the vertical direction of the display area 11 and emit detection light (hereinafter referred to as “horizontal detection light”) in the horizontal direction of the display area 11. 31 and a light receiving unit 32 for receiving horizontal detection light.

  The vertical detection light is light that is irradiated above the touch panel unit 20 in parallel with the touch panel unit 20, and the horizontal region of the display area 11 is substantially covered by each vertical detection light. Assuming that the touch panel unit 20 is pressed, when the operating finger passes through the vertical detection light and approaches the touch panel unit 20, any of the vertical detection light is blocked, and corresponding detection is performed on the light receiving unit 32 side. The intensity changes. The light receiving unit 32 holds a correspondence relationship between the horizontal coordinate information corresponding to each vertical detection light and the detection intensity when the light detection unit 32 is blocked. The horizontal coordinate information that has passed through the detection area 33 is detected.

  On the other hand, the horizontal detection light is light that is irradiated above the touch panel unit 20 in parallel with the touch panel unit 20, and the vertical direction region of the display area 11 is substantially covered by each horizontal detection light. Assuming that the touch panel unit 20 is pressed, when the operating finger passes the horizontal detection light and approaches the touch panel unit 20, any of the horizontal detection light is blocked. Correspondingly, the detection intensity on the light receiving unit 32 side changes. The light receiving unit 32 holds a correspondence relationship between the vertical coordinate information corresponding to each horizontal detection light and the detection intensity when the light detection unit 32 is blocked. The vertical coordinate information that has passed through the detection area 33 is detected.

  By such vertical detection light and horizontal detection light, a detection area 33 of a two-dimensional region parallel to the touch panel unit 20 is set above the touch panel unit 20, that is, above the display area, and passes through the detection area 33. The position (coordinate information) in the horizontal direction and the vertical direction of the operating finger approaching the first touch panel unit is detected. The detected coordinate information is output to the control unit as predicted coordinates. The coordinate information set in the detection unit 30 is set in a positional relationship with the coordinate information set in the display area 11 of the display unit 10, and the predicted coordinates are displayed in correspondence with the operation finger. The coordinates on the area 11 will be shown.

  The control unit 40 determines information to be displayed in the display area 11 of the display unit 10 and changes the display state of the display area 11 based on the pressed coordinates from the touch panel unit 20 or the predicted coordinates from the detection unit 30. Next, the display unit 10 is controlled. In the present embodiment, for example, the control unit 40 sets a display component to be displayed in the display area 11 as a display target component S in order to set a display state according to various scenes based on a preset control program. decide. The display component is a symbol of image data or text data to which various functions are assigned and displayed in the display area 11. This display component includes a component that can be selected by the operator and a component that represents the device and the environmental state and cannot be selected by the operator. The control unit 40 controls the display unit 10 so that the determined display target component S is displayed in the display area 11 based on the display coordinates stored in the storage unit 50.

  FIG. 4 is a diagram for explaining component information stored in the storage unit 50. The component information is configured by associating a display coordinate and a predicted coordinate range for each display component. The display coordinates are coordinate information that defines the display position in the display area 11. For example, when the display component is a rectangular symbol, the position where the center point of the symbol is displayed is defined by the display coordinates. The predicted coordinate range indicates a range on the display area 11 included in the display component displayed according to the display coordinates. For example, when the display component is a rectangular symbol, the predicted coordinate range is set by coordinate information A to D of four points representing each corner of the display component. Note that a plurality of display coordinates and predicted coordinate ranges may be set for a single display component, and individual display can be performed by appropriately selecting according to the number of display target components S displayed in the display area 11. It is also possible to adjust so that the target component S is offset.

  As one of the features of the present embodiment, when a predicted coordinate is output from the detection unit 30, the control unit 40 searches the storage unit 50 based on the predicted coordinate. Then, the control unit 40 specifies the display target component S associated with the predicted coordinate range including the predicted coordinate as the pressed predicted component. And the control part 40 changes the display state of the display target component S based on the viewpoint which assists the pressing operation to the touch panel part 20 which makes the specified pressing prediction component target. On the other hand, when the predicted coordinate range including the predicted coordinates does not exist, or when there is a display component associated with the predicted coordinate range corresponding to the predicted coordinates, the control unit 40 is not the display target component S. The display state of the display target component S is maintained as it is.

  Hereinafter, a display mode change mode will be described with reference to the drawings. The display state can be changed as appropriate from the following patterns. In each figure, (a) shows the display state before the change, and (b) shows the display state after the change.

  FIG. 5 is an explanatory diagram schematically showing a first modification. For example, it is assumed that “component A” is displayed as the display target component S as an initial display state in a certain scene. When the control unit 40 determines that “component A” is a pressed predicted component based on the predicted coordinates, the size of the outline of the component remains the same and the character information is from the initial display state (before the display state is changed). In addition, the display state of the display target component S is changed so as to be bold. As a result, the press prediction component is visually highlighted.

  FIG. 6 is an explanatory diagram schematically showing a second modification. For example, it is assumed that “component A” to “component C” are displayed as the display target component S as an initial display state in a certain scene. When the control unit 40 determines that “part A” is a predicted press part based on the predicted coordinates, the display target part S other than “part A” that is the predicted press part, that is, “part B” and “part B”. The display state of the display target component S is changed so that “component C” is not displayed. As a result, only the press predicted component is displayed.

  FIG. 7 is an explanatory diagram schematically showing a third modification. For example, it is assumed that “component A” to “component C” are displayed as the display target component S as an initial display state in a certain scene. When the control unit 40 determines that “part A” is a predicted press part based on the predicted coordinates, the display target part S other than “part A” that is the predicted press part, that is, “part B” and “part B”. The display state of the display target component S is changed so that the “component C” is unclear from the initial display state (before the display state is changed). For example, the outline of “component B” and “component C” is changed to a broken line. As a result, the press predicted component is highlighted as compared with other display target components.

  FIG. 8 is an explanatory diagram schematically showing a fourth modification. For example, it is assumed that “component A” is displayed as the display target component S as an initial display state in a certain scene. When the control unit 40 determines that “component A” is a pressed predicted component based on the predicted coordinates, the outer shape of the display target component S is enlarged from the initial display state (before the display state is changed). The display state of the display target component S is changed. As a result, the press predicted component is highlighted in size.

  FIG. 9 is an explanatory diagram schematically showing a fifth modification. For example, it is assumed that “component A” to “component P” are displayed as display target components S as an initial display state in a certain scene. When the control unit 40 determines that “part E” is a predicted press part based on the predicted coordinates, the control unit 40 determines a predetermined range around the display coordinates based on the display coordinates related to “part E” that is the predicted press part. The display target component S included therein is specified as the peripheral display component. For example, “part A” to “part I” (excluding “part E”) existing around “part E” are specified as peripheral display parts. And the control part 40 is expanded so that "part E" which is a pressing prediction part, and peripheral display parts (except for "part E") may be expanded rather than an initial display state (before a display state change). The display state of the display target component S is changed. As a result, the pressed predicted component and the display target component S around it are highlighted in size.

  FIG. 10 is an explanatory diagram schematically showing a fifth modification. For example, in an initial display state in a certain scene, as the display target component S, “part A” to “component F” that are the first display target components S that can be operated by the operator, and the first that cannot be operated by the operator. It is assumed that “part 1” and “part 2”, which are the display target parts S 2, are displayed. When the control unit 40 determines that “part A” is the predicted press part based on the predicted coordinates, the “part A” that is the predicted press part and the first display target component S “other than the predicted press part S”. The display state of the display target component S is changed so that the components B ”to“ component F ”are enlarged from the initial display state (before the display state is changed) and are aligned. As a result, the pressing predicted component and the first display target component S that can be operated by the operator are highlighted in size.

  FIG. 11 is an explanatory diagram schematically showing a sixth modification. For example, in an initial display state in a certain scene, as the display target component S, “part A” to “component F” that are the first display target components S that can be operated by the operator, and the first that cannot be operated by the operator. It is assumed that “part 1” and “part 2”, which are the display target parts S 2, are displayed. When the control unit 40 determines that “part A” is the predicted press part based on the predicted coordinates, the “part A” that is the predicted press part and the first display target component S “other than the predicted press part S”. The display state of the display target component S is changed so that the parts B "to" component F "are enlarged from the initial display state (before the display state is changed). At the same time, as shown by (A) to (F) in the figure, the display state of the display target component S is changed so that the functions of those display components are displayed. As a result, the pressing predicted component and the first display target component S that can be operated by the operator are highlighted in size, and individual functions are expressed.

  When acquiring the pressed coordinates from the touch panel unit 20, the control unit 40 specifies the display target component S displayed in correspondence with the pressed coordinates based on the pressed coordinates, and the specified display target The process assigned to the component S is executed (for example, the device is controlled or the display state is changed to a different scene). Here, the control unit 40 changes the display form of the display target component S as described above. Therefore, when specifying the positional correspondence between the pressed coordinates and the display target component S, the predicted coordinate range after changing the display form is stored in advance in the storage unit 50 for each display component, and the pressed It is preferable to execute based on the coordinates and the predicted coordinate range after the display form change. However, the control part 40 may hold | maintain a display coordinate and its prediction coordinate range based on the result of a display form change process, and may refer to this.

  Hereinafter, the basic operation (display method) of the display device having such a configuration will be described. This operation is executed by the control unit 40.

  First, a display component to be displayed in the display area 11 is determined as a display target component S according to a certain scene. Then, the control unit 40 controls the display unit 10 to display the determined display target component S in the display area. Next, the control unit 40 determines whether or not the predicted coordinates are acquired from the detection unit 30. When the predicted coordinates are acquired, the control unit 40 searches the component information stored in the storage unit 50, and the display target component S associated with the predicted coordinate range including the predicted coordinates is a pressed predicted component. Is identified. Then, the control unit 40 changes the display state of the display target component S based on the press predicted component. Next, the control unit 40 determines whether or not the pressed coordinates are acquired from the touch panel unit 20. When the pressed coordinates are acquired, the control unit 40 identifies the display target component S corresponding to the pressed coordinates and executes the function assigned to the specified display target component S.

  As described above, according to the present embodiment, for each display component, the storage unit 50 stores the component information associated with the predicted coordinate range. Therefore, referring to this component information, it is possible to achieve a positional correspondence between the predicted coordinate and the predicted coordinate range, and the pressed predicted component can be specified. Thereby, the display target component to be selected by the operator can be specified before the touch panel unit 20 is pressed. Therefore, since it is before the pressing operation of the touch panel unit 20, that is, before the substantial selection by the operator is performed, various processes can be realized based on the pressing prediction component. As a result, the operability for the operator can be improved.

  In addition, according to the present embodiment, the display state of the display target component S is changed based on the viewpoint of assisting the pressing operation on the touch panel unit 20 that targets the predicted pressing component. By changing the display mode, it is possible to assist the pressing operation on the touch panel unit 20, so that it is possible to improve the operability for the operator.

  For example, in the form shown in FIG. 5, the display target component (pressed prediction component) that the operator wants to perform a pressing operation can be clearly recognized, and the subsequent operation determination can be easily performed from there. For example, in the form shown in FIG. 6, since only the predicted press part can be recognized, it is possible to easily determine the operation after that. For example, in the form shown in FIG. 7, the pressed prediction component is emphasized as compared with the other display target components S, so that it is possible to easily determine the operation after that. For example, in the form shown in FIG. 8, since the press prediction part is displayed in an enlarged manner, it is possible to easily determine the operation after that, and the area detected by the press operation is widened. It is possible to improve the performance. For example, in the form shown in FIG. 9, since the press prediction component and the peripheral display component are displayed in an enlarged manner, it is possible to easily determine the operation including the both components, and to detect the press operation. Therefore, the operability for the operator can be improved. For example, in the form shown in FIG. 10, the press prediction component and the first display target component S other than the press prediction component are displayed in an enlarged manner and aligned, so that it is easy to determine the operation after that including both components. In addition, the area detected by the pressing operation can be increased, so that the operability for the operator can be improved. For example, in the form shown in FIG. 11, the pressed display component and the first display target component S other than the pressed prediction component are displayed in an enlarged manner and the function is displayed. Judgment can be made easily, and the area detected by the pressing operation is widened, so that the operability for the operator can be improved.

  In addition, when the pressing prediction component is specified, the control unit 40 may output the function executed by the pressing prediction component via the audio output unit 60. As a result, information can be given audibly to the operator, so that it is possible to easily determine the operation after that.

  In addition, when the display state is changed based on the press predicted component, the control unit 40 sets the display state to the initial display state (display state) on the condition that the pressed coordinates are not output from the touch panel unit 20 even after a predetermined time has elapsed. It is preferable to return to the state before change.

  In the above-described embodiment, the predicted range coordinates are a range on the display area 11 included in the display component, but the present invention is not limited to this. For example, you may set widely so that the peripheral region of a display component may be included.

(Second Embodiment)
FIG. 12 is an explanatory diagram illustrating a configuration of the detection unit 30 according to the second embodiment. The antenna device according to the second embodiment is different from that of the first embodiment in the configuration of the detection unit 30. Since the configuration other than the detection unit 30 is the same as that of the first embodiment, detailed description thereof is omitted.

  In the present embodiment, the detection unit 30 includes a second touch panel unit 34 different from the touch panel unit (hereinafter referred to as “first touch panel unit”) 20 described above. The second touch panel unit 34 is disposed so as to overlap the upper surface of the first touch panel unit 20, and its own surface is a detection area (a detection area as a detection unit 30 set above the touch panel unit 20. ).

  For the second touch panel unit 34, a resistive film type analog touch panel or the like can be used as in the first touch panel unit 20. In the second touch panel unit 34, when the upper transparent electrode plate is pressed with the operation finger, the coordinate information of the contact point is detected by measuring the electrical resistance, and this is the operation finger pressing the touch panel unit 20. The predicted coordinates are output to the control unit 40. Here, the second touch panel unit 34 is set to a second pressing pressure that is higher than the first pressing pressure that is the detection sensitivity of the first touch panel unit 20. That is, the first pressing pressure is set to a value larger than the second pressing pressure. Therefore, assuming that the operation of the first touch panel unit 20 is performed, when the second touch panel unit 34 disposed on the upper surface thereof is pressed, before the pressed coordinates are output by the first touch panel unit 20. In addition, the predicted coordinates are output to the control unit 40.

  Then, the control unit 40 changes the display state described above based on the predicted coordinates. In addition, since the original pressing operation to the first touch panel unit 20 is performed via the second touch panel unit 34 after the display state is changed, the state is continued after the display state is changed. Within the range, the predicted coordinates from the second touch panel unit 34 may be ignored.

  As described above, according to the present embodiment, it is possible to specify the display target component to be selected by the operator before pressing the first touch panel unit 20. Therefore, since it is before the pressing operation of the first touch panel unit 20, that is, before the substantial selection is performed by the operator, various processes can be realized based on the pressing prediction component. Thus, the operability for the operator can be improved.

  In addition, this invention which showed the structure of the detection part 30 in each embodiment is not limited to this. In the detection area set above the touch panel unit (first touch panel unit) 30, any detection means may be applied as long as it is configured to detect the position of the operating finger on the premise that the touch panel unit 20 is pressed. Can do.

  Note that the computer program itself for causing the display device in which the touch panel unit is provided above the display area of the display unit to execute the display method of the above-described embodiment also functions as part of the present invention. Of course, a recording medium on which the computer program is recorded may be supplied to a system having the configuration as shown in FIG. In this case, the control unit 40 in this system can achieve the object of the present invention by reading and executing the computer program stored in the recording medium. Since the computer program itself realizes the novel functions of the present invention, a recording medium on which the program is recorded also constitutes the present invention. Examples of the recording medium on which the computer program is recorded include a CD-ROM, a flexible disk, a hard disk, a memory card, an optical disk, a DVD ROM, and a DVD-RAM.
