Description

  The present invention relates to a touch panel device that performs a data input operation by touching with a fingertip or the like.

  A touch panel device that performs an input operation by touching with a finger or the like is used in various information terminal devices, portable terminals, and the like, and the types and operation methods are diversified. In this touch panel device, a transparent touch panel is disposed on the screen of the display unit, and data is input by touching the surface of the touch panel.

  The coordinates on the touch panel and the coordinates of the display unit have consistency, and it is determined that the button is operated when the touch panel on the button displayed on the display unit is touched. Therefore, the operation of the touch panel device needs to touch the touch panel on the button to be operated accurately.

  This operation has no problem for a healthy person and can touch the touch panel at the exact position on the button to be operated. However, for example, a person with a disability, such as an elderly person, especially a handicapped person, is difficult to operate an accurate position, and erroneous input may occur.

  Further, even a healthy person concentrates on driving in navigation and other operations, and cannot operate by paying attention to the screen, and may accidentally press a button other than the intended button.

  In view of such a problem, a data input device disclosed in Japanese Patent Laid-Open No. 11-45141 has been proposed. The data input device includes a display unit, a touch panel disposed on the display unit, a coordinate detection unit that detects which part of the display unit the part touching the touch panel device corresponds to, A button identification determination unit that determines whether or not a button displayed on the display unit has been operated by touching the touch panel; and a coordinate within a button identification range assigned to the button is continuously displayed. Then, when the touched time exceeds a predetermined operation time, the button identifying unit determines that the button has been operated.

  With this configuration, even if the data input device touches a button other than the button to be operated, the data input device does not immediately determine that the button has been operated, thereby reducing the occurrence of erroneous input and making the user feel bothered by input. Things have decreased.

  Further, the data input device has a configuration in which the vicinity of the point touched first on the touch panel is enlarged and displayed on the display unit. With this configuration, when the user tries to operate the button, the button on the display unit is automatically enlarged and displayed, so that it is possible to further prevent an erroneous input by the user.

However, since the data input device determines whether or not the operation has been performed after a certain operation time has elapsed, there is a problem in that the operation requires more time than the operation time and a quick operation cannot be performed. In addition, by enlarging the vicinity of the point touched first, it is possible to make it easier for the user to see the part to be touched, but depending on the touch position, the part other than the button to be operated may be enlarged and displayed. There were also cases where the operability was not improved.

  Further, the control unit changes the display mode of the display unit according to the coordinates of the touch position. Furthermore, the said control part changes the display mode of the said display part according to the contact pressure of the said touch panel. Moreover, the said control part is good also as changing the display mode of the said display part according to the contact time of the said touch panel.

  The present invention also provides a user operation process in a touch panel device including a display unit that displays one or more input items, and a touch panel that is arranged on the display unit and that allows an operator to perform an input operation by touch. An operation support method for a touch panel device to support, the step of detecting coordinates of a touch position by a touch operation on the touch panel, and whether or not the coordinates of the touch position detected above correspond to a display position of an input item. And a step of changing the display mode of the display unit when the coordinates of the display position and the touch position do not correspond to the display position of the input item. is there.

  In addition, the present invention is an operation support program for a touch panel device that supports a user's operation processing in a touch panel device that includes a display unit that displays one or more input items, and a touch panel disposed on the display unit. Detecting the coordinates of the touch position by the touch operation on the touch panel, determining whether or not the coordinates of the touch position detected above correspond to the display position of the input item, and the coordinates of the touch position Is an operation support program for a touch panel device capable of executing, by a computer, the step of changing the display mode of the display unit when the input item does not correspond to the display position of the input item.

Moreover, even in situations where the user cannot concentrate on the screen, such as during driving, good operability without erroneous input can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of the touch panel device according to the first embodiment. Reference numeral 1 denotes a touch panel, which is arranged on the screen of the liquid crystal display unit 2. That is, when the user tries to touch a key or the like displayed on the liquid crystal display unit 2, the user actually touches the touch panel 1. In the following description, a liquid crystal display unit will be described as a display unit. However, any display device such as a CRT display, a plasma display, or an organic EL display can be used without being a liquid crystal display unit.

  Reference numeral 3 denotes coordinate detection means for detecting the touch position where the user touches the touch panel, and the coordinates of the keys of the liquid crystal display unit which are displayed as appropriately changed according to the operation screen. The coordinates developed on the touch panel 1 and the coordinates developed on the liquid crystal display unit 2 are the same.

  Reference numeral 4 denotes pressure detection means that receives the coordinates of the touch position from the coordinate detection means and detects the contact pressure at the position touched by the user. The pressure detection means 4 is a pressure sensor disposed on the back surface of the touch panel 1. If the contact pressure is greater than or equal to a predetermined value (P1), the display mode of the liquid crystal display unit is regarded as a normal operation (the key at that position is operated), and if it is less than the predetermined value (P1), the operation is not performed at that position The touch position, the key coordinates, and the contact pressure are sent to the control unit.

  Reference numeral 5 denotes a control unit, which receives coordinates and contact pressure from the pressure detection means, and is a normal operation when the contact pressure is P1 or more. When the touch position is a key, the key is operated. Treat as If the touch position is not a key, the process cannot proceed, and error information is sent to the liquid crystal display unit in order to present an error message to the user.

  On the other hand, when the contact pressure received from the pressure detection means is less than P1, the display mode of the liquid crystal display unit is changed as a normal operation (key operation).

  Next, the operation of the touch panel device according to the present embodiment will be described based on the flowchart shown in FIG. The touch panel device according to the present embodiment is an in-vehicle terminal as a car navigation system. In the present embodiment, an enlarged display will be described as an example among changes in various display modes.

  First, the user reads a key and a map displayed on the liquid crystal display unit 2 through the touch panel 1. On the liquid crystal display unit 2 of the touch panel device, as shown in FIG. 3, a screen showing the current road condition and a map screen showing the current position are displayed. , “OFF”, “information”, “display change”, “re-search”, “point registration”, and “wide area”, a total of seven keys are displayed (step 1).

  When the touch panel 1 is touched by the user (step 2), the coordinate detection means 3 of the touch panel device detects the touch position and the key coordinates (step 3). Next, the pressure detecting means that receives the coordinates of the touch position detects whether the contact pressure at the touch position is P1 or more (step 4).

  When the contact pressure is P1 or more, it is determined whether or not the coordinates of the touch position are coincident with the coordinates of the key (step 5). When the coordinates of the touch position and the coordinates of the key coincide with each other, an operation process is performed assuming that the key operation at the touch position is performed (step 6).

  On the other hand, when the coordinates of the touch position and the coordinates of the key do not match, the operation processing cannot be performed because the part that is not the key is operated, and a message such as “Please select a key” or a buzzer sound is displayed. An error is displayed to inform the user that the operation process cannot be performed (step 7). After the error display prompts the user to perform another operation process, the display returns to the normal display screen (see FIG. 3).

  On the other hand, when the contact pressure is less than P1, it is determined that the user has not performed an operation process, and the display mode of the liquid crystal display unit is changed (step 8). Specifically, for example, the periphery of the touch position is enlarged and displayed at four magnifications (see FIG. 4). Thereafter, in the same manner as described above, the process is repeated after waiting for the user to perform another touch operation.

  The touch panel device according to the first embodiment can display the vicinity of the touch position so as to be easily seen by the user by performing the enlarged display, and can prompt the user to perform an accurate key operation. In particular, when the keys are arranged close to each other, erroneous input can be reduced. Further, since it is determined by the contact pressure whether or not the user has operated, it is possible to determine whether or not the user has operated immediately. Therefore, the time lag is reduced, and it is possible to perform quick processing.

  In the first embodiment, the surroundings of the touch position are enlarged and displayed at four magnifications. However, it is desirable to change the magnification to be appropriately changed. For example, a “change magnification” key is provided so that the user can change the magnification. You may make it selectable.

  Further, in the first embodiment, the enlarged display is performed with the touch position as the center, but the liquid crystal display unit 2 is divided and controlled in advance so as to enlarge and display the section including the coordinates of the touch position. It may be configured, and when a key is displayed in a section including the coordinates of the touch position, the display mode of the section may be changed. By performing the control based on the section, it is not necessary to detect the touch position and the exact coordinates of the key every time the operation is performed, and the control can be simplified. Therefore, accurate and quick processing can be performed.

  Further, in the control divided into the sections, when a key is not displayed in the section including the coordinates of the touch position, the display mode of the section adjacent to the section may be changed.

  When the key is not arranged in the section including the touch position touched by the user, it can be said that the user has touched a position away from the key to be pressed. Therefore, the display mode of the section adjacent to the section including the touch position is changed. Thereby, the user can visually recognize a section having a different display mode, select a key to be pressed, and perform an operation. That is, the user can be prompted to select the correct key.

  In addition, the touch panel device according to the present invention may further include a section setting receiving unit that receives a setting of the number of divisions of the section. The section setting accepting means is means for accepting a change in the number of divisions set in advance. By providing this section setting accepting means, the number of divisions set appropriately in advance, such as a quarter, an eighth, a sixteenth, etc. of the entire display unit can be changed by individual users. The user can change the liquid crystal display unit so that it is easy to see.

<Embodiment 2>
The second embodiment is an example in which the change mode of the display screen is different from that of the first embodiment. Since the schematic configuration of the touch panel device is the same, description thereof is omitted using the same reference numerals. Less than,
The operation of the touch panel device according to the second embodiment will be described based on the flowchart shown in FIG.

  Steps 1 to 7 are the same as in the first embodiment. When the contact pressure at the touch position touched by the user is less than P1, it is determined that the user has not performed an operation process, and the display mode of the liquid crystal display unit is changed. Specifically, first, it is determined whether or not the coordinates of the touch position coincide with the coordinates of the key (step 9).

  When the coordinates of the touch position coincide with the coordinates of the key, only the key is enlarged and displayed (step 10). For example, when the user touches the “detail” key, the “detail” key is enlarged and displayed on the screen (see FIG. 6). This is to allow the user to reconfirm whether or not the key to be processed is the key. Thereafter, the process is repeated after waiting for another touch operation.

  On the other hand, when the coordinates of the touch position do not coincide with the coordinates of the key, only the keys arranged around the touch position are enlarged and displayed (step 11). In this case, the nearest key among the keys arranged in the vicinity may be selected and displayed, or a plurality of keys may be selected and displayed. However, it is desirable that the selection be made based on the distance from the touch position where the user touched.

  By selecting and enlarging only the key in this way, it is possible to display a large key on a screen that is a limited space, making it easier for the user to identify the key and further reducing erroneous input. Can do.

  In some cases, the key that the user intended to select is not displayed on the screen after the change. In this case, the screen must be returned to the normal display. Therefore, in the enlarged display in the first embodiment and the second embodiment, it is desirable to display the “return” or “previous screen” key for returning to the previous screen together with the changed display (see FIG. 7). ).

  Further, in the second embodiment, the key is enlarged and displayed on the screen showing the current road condition and the map screen showing the current position. Only the key may be displayed without displaying the screen showing the current position. By displaying only the keys, the keys can be more easily seen and the user can easily select the keys.

  In addition, it may be configured such that display of only keys can be selected even during normal display. For example, by displaying a key for selecting display of only a key such as “display only key” and selecting the key, a display mode that is displayed together with a screen showing the road condition, etc., and display of only the key It is configured so that the mode can be selected. According to the above configuration, when the user wants to operate the key, the key can be easily displayed by displaying only the key.

<Embodiment 3>
The third embodiment is an example in which a change mode is different from that of the above-described embodiment. Since the schematic configuration of the touch panel device is the same, description thereof is omitted using the same reference numerals. The touch panel device according to the third embodiment includes key usage frequency storage means for storing the frequency of use of a pressed key for each key and calculating the frequency of use of the key. The display mode is changed based on the coordinates of the touch position of the person.

  Hereinafter, the operation of the touch panel device according to the third embodiment will be described based on the flowchart shown in FIG. Steps 1 to 10 are the same as those in the second embodiment.

  When the contact pressure at the touch position touched by the user is less than P1, and the coordinates of the touch position do not coincide with the coordinates of the key, an arbitrary number of keys are selected based on the usage frequency stored in the key usage frequency storage means. Select and enlarge the display (step 12).

  Specifically, every time a key is operated, the usage of the key corresponding to the key usage number storage means is counted and stored. Then, when changing the display mode, a key that is frequently used is preferentially enlarged and displayed. The key used for every user has the characteristic, for example, in an in-vehicle terminal, the key used frequently for every user, such as the user who uses a car navigation system frequently, the user who uses a lot of music, etc. differs. Accordingly, by storing the usage frequency for each user and changing the display mode based on the stored data, it is possible to display the key frequently used by the user so that the user can easily press the key.

  Since keys to be operated may not be displayed, keys for selecting a screen on which all keys are displayed, such as “return” and “normal display”, are also displayed in the same manner as described above. It is desirable. In addition, the number of keys displayed here may be set in advance, or may be configured to be set manually by the user.

  Further, in combination with the second embodiment, when displaying the keys around the touch position, the number of keys to be displayed depending on the usage frequency when there are many keys around the touch position and cannot be displayed on the liquid crystal display unit 2. The key size may be changed to fit within the liquid crystal display unit 2.

In the present embodiment, the change in the display mode has been described by taking the enlarged display as an example. However, the change in the display mode of the touch panel device according to the present invention is not limited to the enlarged display, and the color change, the brightness change, Of course, the display includes only the key and the display magnification of the key.
The change in the display mode of the liquid crystal display unit may be any change in the display mode that improves the operability for the user, and various configurations can be adopted. The magnified display is a magnified display of only the keys and the like located around the touch position with reference to the touch position, such as a quarter, an eighth, a sixteenth, etc. including the touch position. Various magnifications can be varied according to the visibility of the user.

  The change in color is to change the color of the surroundings or the keys located in the vicinity based on the coordinates of the touch position. For example, by changing only the periphery of the touch position to a contrasting color with the screen before the change, the periphery of the touch position can be made conspicuous, and the user can easily recognize the key position to be pressed.

  The change in brightness is a partial change in brightness, such as the surrounding area and keys located in the vicinity, based on the coordinates of the touch position. For example, by increasing the brightness of only the keys located around the touch position and lowering the brightness of other keys, the user can easily see the keys around the touch position and the operability is improved.

  The display of only the key means that only the key to be operated is displayed on the liquid crystal display unit, and other images, characters, and the like are not displayed. By displaying only the key, the user can easily select the key because only the key to be pressed is visually recognized. When only keys are displayed, all keys may be displayed, or only arbitrarily selected keys may be displayed, and it is desirable to make various settings according to the usage mode.

  The change in the display magnification of the key is, for example, by enlarging and displaying keys around the touch position, or by reducing and displaying keys other than the periphery of the touch position, so that only the keys around the touch position can be easily seen. It is a configuration.

  In addition, the change of the said display mode may be only the mode of each change illustrated above, and may combine these as much as possible.

  In addition, the touch panel device according to the present invention may further include a change mode receiving unit that receives the setting of the change of the display mode. As described above, the change of the display mode in the present invention includes various change modes such as enlarged display, color change, brightness change, key only display, and key display magnification.

    Of the various change modes, which display mode change is easy to recognize depends on the user. When the user himself selects the type of change in the display mode, the display mode can be changed to be more easily recognized by the user. By providing the display mode receiving means, a touch panel device suitable for the user can be provided. In addition, a key for accepting the change in the display mode may be displayed on the liquid crystal display unit and touched in the same manner as the key operation to accept the change in the display mode.

  The display mode accepting unit can accept selection of display modes such as enlarged display, color change, lightness change, key only display, and key display magnification. This includes selection of the size of the key to be displayed.

  For example, in the above-described embodiment, the key display magnification is set in advance, but it may be configured so that the user can set it individually. For example, a “button magnification” key may be displayed so that the user can set the display magnification of the key by himself / herself.

  Furthermore, in the above-described embodiment, when a touch operation less than P1 is performed again, the display may be further enlarged, or may be configured to change other display modes such as a color change.

  In addition, the touch panel device may display the screen in which the display mode is changed and the screen before the display mode is changed side by side. By displaying the screens side by side, for example, if the touched location is an accurate position, the screen can be operated on the screen after the change, and if the touched location is incorrect, the operation can be performed on the screen before the change. . That is, by displaying both screens side by side, the user can select and operate an easy-to-operate screen, and the user can operate on the screen that is easier for the user to operate.

<Embodiment 4>
The fourth embodiment is an embodiment in which the discrimination mode of the input operation is different from that of the previous embodiment. Since the schematic configuration of the touch panel device is the same, description thereof is omitted using the same reference numerals. The operation of the touch panel device will be described based on the display screen shown in FIG.

  FIG. 9 is a diagram showing a change in display mode, where (a) is before the change, and (b) is a screen after the change when (2) shown in the figure is touched. Similarly, (c) shows the screen after change when the touch operation is performed on (3) and (d) shown in the drawing.

  The touch panel device according to Embodiment 4 is configured to change the display in accordance with the touch-operated position. When (1) and (4) shown in the figure, which are button display positions, are touch-operated, the “detail” or “OFF” button displayed at the positions (1) and (4) is surely operated. The input is confirmed directly without switching to the enlarged display.

Also, when the position (2) shown in the figure is touched, the nearest button is the “detail” button, so it is determined that the position (2) is touched accidentally by trying to press the “detail” button. To do. In this case, the “detail” button is enlarged and displayed as shown in FIG.

  When the position (3) shown in the figure is touched, the distance between the “detail” button and the “OFF” button is almost equal, and thus it cannot be determined which one is being pressed. For this reason, as shown in FIG. 9C, the “detail” button and the “OFF” button are enlarged and displayed in substantially the same size.

  When a touch operation is performed at the position (5) shown in the figure, it is far from any button, and it cannot be determined which button is to be operated. Therefore, the area around the touch operation is simply displayed in an enlarged manner.

  Further, it may be configured such that not only the button closest to the position of the touch operation is enlarged but also the next closest button is displayed in an overlapping manner. For example, as shown in FIG. 10C, when the position of (2) is touch-operated, the nearest button is “detail”, but the “off” button is also close, so the “detail” button is expanded. In addition to the display, the “OFF” button may be enlarged and displayed a little smaller. Further, the ratio of the size of the buttons to be displayed may be changed according to the distance from each button.

  Further, as a modified example, as shown in FIG. 11, even when the touched position is in the button, if the position is close to the periphery of the button, the display may be enlarged.

  For example, when the range (1) surrounded by the inner dotted line shown in FIG. 11A is touch-operated, it is determined that the “detail” button has been selected, and direct input is performed without performing enlarged display. Determine.

  Also, if you touch the area (2) between the inner and outer dotted lines, it is highly likely that the “Details” button has been pressed. An enlarged display is displayed (FIG. 11B).

  Furthermore, if the area outside the dotted line (3) is touch-operated, the button may have been pressed, but it may have just been touched to center the map near the button. , The area around the button is simply enlarged (FIG. 11C).

  When the user touches the position (4) shown in FIG. 11 (c) again, the enlarged display is canceled and the display returns to the normal scale display in which the position (4) is centered (FIG. 11). (D)).

  In the above description, in order to determine the distance between the touch position and the button, as illustrated in FIG. 12A, the distance between the displayed object and the geometric stop position may be determined as a reference. Alternatively, the determination may be made by the distance from the touch position to the nearest side or vertex.

  If the geometric center cannot be clearly defined as in an indefinite object, the distance from the center of gravity of the object may be obtained and used as a reference, or as shown in FIG. The determination may be made with reference to a defined reference point (● shown in the figure, which is not actually visually recognized). In this case, the reference point does not necessarily have to be included in the object, and may be outside the object or away from the object. For example, it can be suitably used when the object is a character as shown in FIG.

<Embodiment 5>
The fifth embodiment is an embodiment in which the display magnification of the button is changed stepwise based on the pressing force of the input operation. Since the schematic configuration of the touch panel device is the same, description thereof is omitted using the same reference numerals. The operation of the touch panel device will be described based on the display screen shown in FIG.

FIG. 13 is a diagram showing a change in the display mode, and (a) is before the change. (B) is the screen after the change when the touch operation of (1) shown in the figure is performed with a small pressing force, and (c) is the screen after the change when the touch operation is performed with (1) with a smaller pressing force. It is. (D) is a screen after change when the touch operation is performed with (2) with a large pressing force and (e) with (2) with a small pressing force.

  When the position (1) shown in FIG. 13A is touch-operated and the pressing force is equal to or greater than a predetermined value, it is determined that the “details” button has been pressed, and direct input is performed without performing enlarged display. Confirm (not shown).

  If the pressing force is smaller than the predetermined pressure value, there is a possibility that the “details” button has been pressed, but it cannot be determined, so the “details” button is enlarged (FIG. 13B). In addition, if it is smaller than the pressing force, there is a possibility that the “Detail” button is accidentally touched when trying to press the “OFF” button, so both the “Detail” button and the “OFF” button are An enlarged display is displayed (FIG. 13C).

  Furthermore, when controlling the position and the pressing force in combination, for example, when the position (2) is touch-operated, and the pressing force is larger than a predetermined pressure value, it is possible to make a mistake when trying to press the “detail” button. The “detail” button is enlarged and displayed (FIG. 13D). On the other hand, when the pressing force is smaller than the predetermined pressure value, it is impossible to determine which of the “detail” button and “OFF” is wrong, so both the “detail” button and the “OFF” button are enlarged and displayed (see FIG. 13 (e)).

  In addition, as a method of detecting the pressing force, for example, in the case of a resistance-type touch panel, it can be determined by the magnitude of the resistance value. It is also possible to indirectly determine the pressing force from the contact area when the touch operation is performed.

<Embodiment 6>
In the sixth embodiment, the display magnification of the buttons is changed stepwise based on the pressing force of the input operation. Since the schematic configuration of the touch panel device is the same, description thereof is omitted using the same reference numerals. The operation of the touch panel device will be described based on the display screen shown in FIG.

  FIG. 14 is a diagram showing a change in the display mode, and (a) is before the change. (B) is the screen after the change when (1) shown in the figure is touched in a short time, and (c) is the screen after the change when (1) is touched in a shorter time. . (D) is a screen after the change when (2) is touched for a long time and (e) is a touch operation for (2) in a short time.

  When the position (1) shown in FIG. 14A is touched with a pressing time longer than a predetermined time, the input is directly confirmed (not shown) on the assumption that the “detail” button has been pressed. On the other hand, if the position of (1) is touched for a time shorter than the predetermined time, the “detail” button may be pressed, but it cannot be determined, so the “detail” button is enlarged (FIG. 14 ( b)). In addition, when the pressing time is shorter than the pressing time, there is a possibility that the “details” button is accidentally touched when trying to press the “OFF” button. Both are enlarged and displayed (FIG. 14C).

Furthermore, when controlling the position and the pressing time in combination, for example, when the position (2) is touch-operated, or when the pressing time is longer than the predetermined time, there is a possibility that the user has made a mistake in trying to press the “detail” button. It is determined that the value is high, and the “details” button is enlarged and displayed (FIG. 14D). On the other hand, if the pressing time is smaller than the predetermined time, it cannot be determined which of the “detail” button and “OFF” is wrong, and therefore both the “detail” button and the “OFF” button are enlarged (FIG. 14 ( e)).

  As described above, in the embodiments, the preferred embodiments of the present invention have been illustrated and described. However, the touch panel device according to the present invention is not limited to the above-described embodiments, and includes combinations thereof as much as possible.
