  Here, “the user's finger has come close to the touch panel 12” means the position of the user's finger in the direction orthogonal to the panel surface of the touch panel 12 (hereinafter referred to as “front-rear direction”). ) Is located within a predetermined distance (for example, within 3 cm) from the panel surface of the touch panel 12. The “proximity position of the user's finger with respect to the touch panel 12” means the position of the user's finger (hereinafter referred to as “up / down / left / right position”) in a plane direction parallel to the panel surface of the touch panel 12 (hereinafter referred to as “up / down / left / right direction”). To do. In order to detect the front / rear position and the vertical / horizontal position of the user's finger, for example, a plurality of proximity sensors 13 are provided near the touch panel 12 as shown in FIG. The unit 21a combines the detection results of the user's finger by each of the plurality of proximity sensors 13 to specify the front / rear position and the up / down / left / right position of the user's finger.

(Configuration-Display control device)
In FIG. 1, when the proximity sensor 13 detects that the user's finger is in proximity to the touch panel 12, the display control device 20 detects the proximity position of the user's finger detected by the proximity sensor 13. The display control means for controlling the display position of the operation button on the liquid crystal panel 11 based on the above. The display control device 20 includes a control unit 21 and a data recording unit 22.

(Configuration-Display control device-Control unit)
The control unit 21 is a control unit that controls the display control device 20, and specifically, a CPU, various programs that are interpreted and executed on the CPU (a basic control program such as an OS, and a program that is started and specified on the OS). And an internal memory such as a RAM for storing the program and various data. In particular, the display program according to the present embodiment is substantially installed in the display control device 20 via an arbitrary recording medium or network, thereby substantially configuring each unit of the control unit 21.

  The control unit 21 includes a detection position specifying unit 21a, a time measurement unit 21b, an operation history processing unit 21c, a display content selection unit 21d, a display size determination unit 21e, and a display position determination unit 21f in terms of functional concept. Has been. The detection position specifying unit 21a is detection position specifying means for specifying the front / rear position and the up / down / left / right position of the user's finger by combining the detection results of the user's finger by each of the plurality of proximity sensors 13. After the proximity sensor 13 detects that the user's finger has approached the touch panel 12, the time measuring unit 21 b maintains the proximity state without the user's finger touching the touch panel 12. It is a time measuring means for measuring time. The operation history processing unit 21 c is an operation history processing unit that processes history information of operations performed by the user using the touch panel 12.

The data recording unit 22 is a recording unit that records a program and various data necessary for the operation of the display control device 20, and is configured using, for example, a hard disk (not shown) as an external storage device. However, any other recording medium including a magnetic recording medium such as a magnetic disk or an optical recording medium such as a DVD or a Blu-ray disk can be used instead of or together with the hard disk.

  In the data recording unit 22, an operation history information database (hereinafter, the database is abbreviated as DB) 22a is recorded. The operation history information DB 22a is an operation history information storage unit that stores operation history information related to an operation history of an operation button by a user. This operation history information includes, for example, an item “operation button” and an item “number of operations” as shown in the configuration example of FIG. 3, and is displayed on the monitor 10 as information corresponding to the item “operation button”. The name of each operation button that may be stored is stored, and as information corresponding to the item “number of operations”, the total number of operations performed so far for each operation button is stored.

(processing)
Next, a display control process executed by the display device 1 configured as described above will be described. FIG. 4 is a flowchart of the display control process (in the following description of each process, step is abbreviated as “S”). This display control process is repeatedly executed after the display device 1 is powered on, for example. Various display screens to be displayed as a car navigation device are displayed on the display device 1. The display screen selection and switching processing is a process different from the display control process described here. It is assumed that the display control process is appropriately executed simultaneously or separately.

  First, the detection position specifying unit 21a of the control unit 21 monitors whether the user's finger has approached the touch panel 12 by monitoring the output from the proximity sensor 13 (SA1). Specifically, when the user's finger is close to the touch panel 12, outputs corresponding to the front and rear positions and the vertical and horizontal positions of the fingers are output from each of the plurality of proximity sensors 13 to the control unit 21. The position specifying unit 21a analyzes the output from each of the proximity sensors 13 by a known method to specify the front / rear position and the upper / lower / left / right position of the finger, and the specified front / rear position is predetermined from the panel surface of the touch panel 12. If the position is within the distance, it is determined that the user's finger is close to the touch panel 12.

  When it is determined that the user's finger is not close to the touch panel 12 (SA1, No), the control unit 21 does not need to continue the display control process, and ends the display control process. On the other hand, when it is determined that the user's finger is close to the touch panel 12 (SA1, Yes), the time measurement unit 21b of the control unit 21 starts time measurement (SA2). Next, the control unit 21 monitors whether the user's finger touches the touch panel 12 by monitoring the output from the touch panel 12 (SA3). Specifically, when the user's finger touches the touch panel 12, an output for specifying the touched position is output from the touch panel 12 to the control unit 21, and thus the control unit 21 has received this output. In this case, it is determined that the user's finger touches the touch panel 12.

  When it is determined that the user's finger has touched the touch panel 12 (SA3, Yes), the control unit 21 receives an operation input (SA4). Specifically, the control unit 21 touches the user's finger on the touch panel 12 with the position of the operation button displayed on the liquid crystal panel 11 at that time and the position specified by the output from the touch panel 12. Based on the determined position, the operation button operated by the user is specified, and a predetermined operation content associated with the operation button is executed. In this case, the operation history processing unit 21c of the control unit 21 updates the operation history information in the operation history information DB 22a by incrementing the number of operations corresponding to the operation button for which the operation input has been accepted in SA4 (SA5). ). Further, the time measuring unit 21b of the control unit 21 stops the time measurement and resets the time that has been measured so far (SA6).

  On the other hand, when it is not determined in SA3 that the user's finger has touched the touch panel 12 (SA3, No), the time measurement unit 21b of the control unit 21 continues the time measurement started in SA2 and After the proximity sensor 13 detects that the user's finger is close, the time during which the proximity state is maintained without the user's finger touching the touch panel 12 is measured. Then, it is determined whether or not the measured time thus measured is equal to or longer than a predetermined activation time set in advance (SA7). Here, the predetermined activation time is set to a time when it can be estimated that the user is not touching the touch panel 12 for some reason, although the user is trying to perform an operation via the touch panel 12. For example, about 2 seconds is set. If it is determined that the measurement time is not equal to or greater than the activation time (SA7, No), the process returns to SA3 and waits until it is determined that the measurement time is equal to or greater than the activation time. However, during this time, if it is determined that the user's finger has moved away from the touch panel 12 (SA8, Yes), it is assumed that the user has stopped the operation, and the process proceeds to SA6.

  When it is determined that the measurement time is equal to or longer than the predetermined activation time (SA7, Yes), the time measurement unit 21b of the control unit 21 determines that the measurement time measured so far by the time measurement started in SA2 is in advance. It is determined whether or not the predetermined change time has been reached (SA9). Here, as the predetermined change time, the user is trying to operate via the touch panel 12, but the user wants to operate with an operation button different from the operation button displayed on the liquid crystal panel 11 at that time. Is set, and a time longer than the startup time is set. Although the specific numerical value of this change time is arbitrary, about 5 seconds are set, for example.

  Here, when it is determined that the measurement time is not equal to or longer than the change time (SA9, No), the display content selection unit 21d of the control unit 21 selects the first priority operation button based on the operation history information (SA10). ). The operation button having the first priority is an operation button to be displayed on the liquid crystal panel 11 when the measurement time is equal to or longer than the activation time and the measurement time is not equal to or longer than the change time. An operation button whose position should be changed. Specifically, the display content selection unit 21d refers to the operation history information stored in the operation history information DB 22a, and selects the operation button corresponding to the highest number of operations as the operation button with the first priority. For example, in the example of the operation history information in FIG. 3, the “map switching” operation button is selected. As the selection method of the operation button of the first priority, various other changes can be made. For example, when a plurality of operation buttons are displayed on the display screen at that time, Among the plurality of operation buttons, an operation button corresponding to the most frequent operation may be selected as the operation button having the first priority. In addition, when only one operation button is displayed on the display screen at that time, the displayed operation button is selected as the operation button of the first priority without referring to the operation history information. May be.

  Next, the display size determination unit 21e determines whether or not the operation buttons having the first priority selected in SA10 can be displayed at a time on the display area of the liquid crystal panel 11 (SA11). Such a determination is made in SA10 because, for example, there may be a plurality of operation buttons corresponding to the highest number of operations, and a plurality of operation buttons having the first priority may be selected. In this case, the plurality of operation buttons having the first priority may not be displayed on the entire display area of the liquid crystal panel 11 at a time. In particular, the display area of the liquid crystal panel 11 in this determination does not necessarily mean the entire display area of the liquid crystal panel 11, for example, when an operation button is displayed only in a part of the entire display area. Means a part of the area, and when the display area is small, the number of operation buttons that can be displayed at one time is reduced. For example, if the number of operation buttons having the first priority selected in SA10 is equal to or less than a predetermined number (for example, 4), the display size determination unit 21e determines that the display can be performed on the liquid crystal panel 11 at a time. To do.

  When it is determined that the first priority operation button can be displayed at one time (SA11, Yes), the display position determination unit 21f of the control unit 21 selects the first priority operation button selected in SA10. It is displayed near the user's finger (SA12). Specifically, the display position determination unit 21f displays the operation button having the first priority selected in SA10 at a position close to the vertical and horizontal positions of the user's finger specified in SA1. 11 is controlled. For example, when there is only one operation button with the first priority, the center position of the operation button is set to a position corresponding to the vertical and horizontal positions of the user's finger. Alternatively, when there are a plurality of first priority operation buttons, the plurality of operation buttons are arranged vertically or horizontally, and the center position of the plurality of operation buttons arranged in parallel is set to the top and bottom of the user's finger. The position corresponds to the left / right position. As the position determination method, various other changes can be made. For example, when there is an area where information other than the operation buttons is always displayed on the display screen, the area is excluded. The operation button may be displayed at a position closest to the vertical and horizontal positions of the user's finger in the area.

  FIG. 5 shows an example of a display screen before displaying the operation button with the first priority, and FIG. 6 shows an example of the display screen after displaying the operation button with the first priority by the processing of SA12. As shown in FIG. 5, a map is displayed on the display screen, and on the left side of the display, operation buttons for “map enlargement”, “map reduction”, “map switching”, and “volume adjustment” are displayed. It is lined up and down. As shown in FIG. 6, a map and operation buttons similar to those shown in FIG. 5 are displayed on the display screen. It is displayed at the position corresponding to the position. Therefore, it appears to the user that the “map switching” operation button has moved from the position in FIG. 5 to the position in FIG. 6, and the operation button can be easily operated.

  On the other hand, when it is determined in FIG. 4 that the operation buttons having the first priority cannot be displayed at one time (SA11, No), the display size determining unit 21e of the control unit 21 selects the first priority selected in SA10. The operation button is reduced or the position of the operation button having the first priority selected in SA10 is changed and displayed near the user's finger (SA13). Whether to reduce the operation button or change the position of the operation button can be determined by various methods. For example, when the priority order between these two methods is set in advance and priority is given to changing the arrangement position of the operation buttons, the first priority can be changed by changing the arrangement position of the operation buttons. It is determined whether or not the operation buttons can be displayed at one time. If it is determined that the operation buttons can be displayed, the arrangement position of the operation buttons is changed. Reduce the operation button.

  When the operation buttons are reduced, specifically, the display position determination unit 21f sums up the predetermined standard display areas of the operation buttons having the first priority selected in SA10, and the total value and the liquid crystal panel. 11, the reduction ratio for displaying all the operation buttons of the first priority in the operation button display area in the liquid crystal panel 11 at a time is calculated. Then, the reduced display area is calculated by multiplying the calculated reduction rate by the standard display area, and the first priority operation button is displayed based on the calculated display area. The display position of the operation button at this time can be determined basically in the same manner as SA12.

  FIG. 7 shows an example of a display screen after the operation buttons of the first priority are reduced and displayed by the processing of SA13. As shown in FIG. 7, a map and operation buttons similar to those in FIG. 5 are basically displayed on the display screen, but “map switching” is displayed at a position corresponding to the vertical and horizontal positions of the user's finger. "Operation buttons" and "volume adjustment" operation buttons are displayed. Here, it is assumed that there is only one operation button display area in the area corresponding to the vertical and horizontal positions of the user's finger. For this reason, the operation buttons for “map switching” and “volume adjustment” The operation buttons are displayed by being reduced to a half display area as compared with the standard display area shown in FIG. Therefore, it appears to the user that the “map switching” operation button and the “volume adjustment” operation button have moved from the position in FIG. 5 to the position in FIG. One operation button can be selected and operated easily.

  FIG. 8 shows an example of a display screen after the operation buttons of the first priority are rearranged and displayed by the process of SA13. As shown in FIG. 8, a map and operation buttons similar to those in FIG. 5 are basically displayed on the display screen, but “map switching” is displayed at a position corresponding to the vertical and horizontal positions of the user's finger. "Operation buttons" and "volume adjustment" operation buttons are displayed. Here, it is assumed that the area corresponding to the vertical and horizontal positions of the user's finger has only a horizontally long display area that is the height of one operation button. In FIG. 5, the operation buttons for “volume adjustment” are arranged in a row along the vertical direction, whereas in FIG. 8, they are arranged in a row along the horizontal direction. Therefore, for the user, the “map switching” operation button and the “volume adjustment” operation button appear to move from the position of FIG. 5 to the position of FIG. One operation button can be selected and operated easily.

  When changing the position of the operation button, specifically, the display position determination unit 21f changes various positions by changing the vertical and horizontal positional relationship between the operation buttons of the first priority selected in SA10. A pattern is created, and the standard display area of each operation button in the created arrangement pattern is summed, and from this total value and the area of the display area of the operation button on the liquid crystal panel 11, all the operation buttons of the first priority are displayed. Is selected at once in the operation button display area of the liquid crystal panel 11. Then, the first priority operation button is displayed according to the selected arrangement pattern. The display position of the operation button at this time can be determined basically in the same manner as SA12.

  After the operation button is displayed in this manner, when a further time elapses without the user's finger touching the touch panel 12, it is determined in SA9 in FIG. 4 that the measurement time is equal to or longer than the change time (SA9). , Yes). When it is determined in this way, the display content selection unit 21d of the control unit 21 determines whether or not a predetermined time has elapsed since the previous change in the display position or arrangement position of the operation buttons (SA14). As the predetermined time, for example, a time of the same length as the change time of SA9 is set, for example, about 5 seconds is set. If the predetermined time or more has not elapsed (SA14, No), the process proceeds to SA11. On the other hand, when the predetermined time or more has elapsed (SA14, Yes), the display content selection unit 21d selects an operation button that is lower in priority by one step than the operation button that performed the previous display based on the operation history information. (SA15). As an operation button whose priority is lower by one step than the operation button that was displayed last time, when the processing of SA15 is executed first, the operation button selected in SA10 (that is, the first priority) In the case where an operation button having a lower priority (that is, an operation button having the second priority) is selected with respect to the operation button) and the process of SA15 is subsequently executed, An operation button having a lower priority than the selected operation button by one level is sequentially selected. For this reason, specifically, the display content selection unit 21d refers to the operation history information stored in the operation history information DB 22a, and uses the operation buttons corresponding to the operation frequency that is the next highest after the operation buttons that were displayed last time. Then, an operation button not displayed on the liquid crystal panel 11 at that time is selected as an operation button to be displayed next. However, various other changes can be made as the method for selecting the operation button. For example, the operation button can be changed based on the operation button selected as the first priority operation button. The operation button with the highest possibility of being operated may be specified as the operation button with the priority to be displayed next.

  Thereafter, the SA11 process is performed on the operation button thus selected, and the SA12 or SA13 process is further performed in the same manner as described above. FIG. 9 shows an example of a display screen after displaying an operation button having a lower priority by one step than the operation button displayed last time by the processing of SA12. As shown in FIG. 9, a map and operation buttons are basically displayed on the display screen in the same manner as in FIG. 6, but at positions corresponding to the vertical and horizontal positions of the user's finger, FIG. In place of the “map switching” operation button, the “map enlargement” operation button is displayed. Therefore, it seems to the user that the operation button of “Map switching” in FIG. 6 has been changed to the operation button of “Enlarge map” in FIG. 9, and the operation button after the change can be easily operated. It becomes possible to do.

(effect)
As described above, according to the present embodiment, since the display position of the operation button on the liquid crystal panel 11 is controlled based on the detected proximity position of the user's finger, the position according to the proximity position of the user's finger. The operation buttons can be displayed on the screen, and even if the user does not move the finger to the correct operation position, the operation button moves to the position corresponding to the finger. It is not necessary to extend the fingertip to the button, and the operation can be performed simply by pressing the operation button that has moved toward the proximity position of the finger, so that the operability of the operation button is improved.

  In addition, since the display position of the operation button is controlled when the time in which the proximity state is maintained without the user's finger touching the touch panel 12 is equal to or longer than a predetermined activation time, the user can By simply stopping the finger in the vicinity, the display control of the operation button can be started, and the display control of the operation button can be easily performed.

  In addition, when the time during which the proximity state is maintained without the user's finger touching the touch panel 12 is longer than a predetermined change time set as a time longer than the predetermined activation time, the operation button is changed to another Since the operation button is changed, the user can change the operation button by simply stopping his / her finger in the vicinity of the touch panel 12 for a certain period of time, and the operation button can be easily changed.

  In addition, since the display position of the operation button is controlled based on the operation history information, for example, when there are a plurality of operation buttons, the operation button most frequently used by the user is displayed at a position close to the finger. It is possible to control the display of operation buttons that match the user's operation history.

  Further, when it is determined that a plurality of operation buttons cannot be displayed on the liquid crystal panel 11 at a time, the display size of at least a part of the plurality of operation buttons is reduced. The operation buttons can be displayed, and the user does not need to switch the operation menu in order to display a plurality of operation buttons, so that the operability is further improved.

  When it is determined that a plurality of operation buttons cannot be displayed on the liquid crystal panel 11 at a time, the arrangement of the plurality of operation buttons is changed. For example, the plurality of operation buttons arranged in a row along the vertical direction. By displaying the operation buttons in a horizontal arrangement along the horizontal direction, or by changing the arrangement, more operation buttons can be displayed on one screen than when the arrangement is not changed. The user does not need to switch the operation menu in order to display a plurality of operation buttons, so that the operability is further improved.

[Modifications to Embodiments]
Although the embodiments of the present invention have been described above, the specific configuration and means of the present invention are arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. be able to. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above contents, and may vary depending on the implementation environment and details of the configuration of the invention. May be solved, or only some of the effects described above may be achieved.

(About display control processing)
When changing the display position or arrangement position of the operation buttons, the display direction and display contents of the operation buttons can also be changed. For example, an operation button that is a horizontally long operation button and operation items are displayed in horizontal writing mode. Can be displayed as a vertically long operation button with the display direction changed, and the operation items can be displayed in vertical writing. When the display size is changed, the display size can be enlarged. For example, when only one operation button having the first priority is selected, a display area close to the user's finger is displayed. In the case of a display area that displays two operation buttons, the operation button of the first priority selected only by one is doubled and displayed in the display area near the user's finger. May be.

  In addition, as a method for changing the operation button display position and the arrangement position, the operation button may be reduced and the operation button arrangement position may be changed simultaneously. For example, when moving a plurality of operation buttons arranged in a line along the vertical direction to a specific display area, the display area is a horizontally long area, and the display of the plurality of operation buttons is performed. If there is only half the area, the plurality of operation buttons may be reduced to a half display size, and the reduced operation buttons may be rearranged in a row.

Part of the display control process shown in FIG. 4 may be omitted. For example, SA5, SA9, SA10, SA11, SA13, SA14, and SA15 may be omitted, and if it is determined Yes in SA7, the process may directly move to SA12. In this case, all the operation buttons displayed on the screen may be displayed in the vicinity of the finger, or the operation buttons selected based on the predetermined priority may be displayed in the vicinity of the finger. Good.
Further, the processing of SA9, SA14, and SA15 may be omitted, and the display position and arrangement position of the operation button may be changed only once when the measurement time is equal to or longer than the activation time. In this case, if SA10 is further omitted and the measurement time is equal to or longer than the activation time, the operation button may be selected based on a predetermined priority without referring to the operation history information.
Alternatively, SA9 and SA10 may be omitted, and when the measurement time becomes equal to or longer than the activation time, operation buttons with a priority one step lower than the previous time may be sequentially selected based on the operation history information.
In addition, SA11 and SA13 are omitted, and the selected operation button is displayed in the vicinity of the finger. If the display cannot be performed without reducing or changing the arrangement, the change of the display position or the arrangement position is stopped. Also good.
