An operation input device according to one embodiment will be described below with reference to the accompanying drawings. FIG. 1 shows an example in which the operation input device 10 is installed in a navigation device, which is an example of electronic equipment. The navigation device includes an operation input device 10 , a display section 21 , a touch panel 22 , a map information storage section 23 and a position information acquisition section 24 .

The operation input device 10 includes a display control unit 11, an operation detection unit 12, an operation response control unit 13, a map information acquisition unit 14, an icon display setting unit 15, a reaction area setting unit 16, a pressed position storage unit 17, and a pressed position distribution detection. 18 and an erroneous operation determination unit 19 . Each of these units is connected to bus 110 . The operation input device 10 may be a microcomputer or an integrated circuit called System-on-a-Chip (SoC). Each component in the operation input device 10 may be functionally configured by software.

The display unit 21 is, for example, a liquid crystal panel. The touch panel 22 is a touch panel of any type such as a resistive type or a capacitive type, and is mounted on the surface of the display section 21 . The map information storage unit 23 is an arbitrary storage medium such as a ROM or a memory card that stores map information. The position information acquisition unit 24 includes, for example, a GNSS receiving unit that receives radio waves from a plurality of satellites for the Global Navigation Satellite System (GNSS), and a position based on the GNSS signal received by the GNSS receiving unit. and a calculating unit for calculating information to acquire position information of the current position. GNSS is GPS (Global Positioning System) as an example.

The operation of each component of the operation input device 10 will be described. The map information acquisition unit 14 acquires map information from the map information storage unit 23 . The map information acquisition unit 14 may acquire map information of a predetermined range including the current position acquired by the position information acquisition unit 24 . The display control unit 11 controls the display unit 21 to display a map based on the map information acquired by the map information acquisition unit 14 . Icons to be superimposed and displayed on the map are set in the icon display setting section 15 . The display control unit 11 causes the icon set by the icon display setting unit 15 to be superimposed on the map displayed on the display unit 21 .

FIG. 2 shows an example of a map on which a plurality of icons are superimposed and displayed on the display unit 21. As shown in FIG. In FIG. 2, a menu icon 31 for displaying a menu is displayed in the lower right corner of the display unit 21, and a submenu open icon 32L for displaying a submenu is displayed on the left side of the menu icon 31. there is The submenu open icon 32L is described as "display L".

A display switching icon 33 for switching the display state of the map on the display unit 21 is displayed in the upper left corner of the display unit 21 . A widening icon 34 and a detailed icon 35 for changing the scale of the map are displayed on the right end of the display section 21 . In the display area 36 between the widening icon 34 and the detailing icon 35, 100 m is written to indicate the scale level of the current map. 100m in the map scale scale indicates, for example, a scale of 1/10,000. The scale of the map displayed on the display unit 21 is selected from the level stored in the non-volatile memory (not shown) when the widening icon 34 or the detailed icon 35 is operated last.

A current position mark 37 indicating the current position of the vehicle in which the navigation device is mounted is displayed at a position lower than the center in the vertical direction in the center in the horizontal direction of the display unit 21 . The display control unit 11 moves the range of the map displayed on the display unit 21 as the vehicle moves. FIG. 2 shows a display format in which the traveling direction of the vehicle is upward. to rotate.

In FIG. 1 , the reaction area setting unit 16 sets a reaction area corresponding to each icon that reacts when the icon is pressed on the touch panel 22 . In the initial setting, the reaction area setting unit 16 sets, for each icon, a reaction area having the same size as that of each icon at the same position as that of each icon. In the example shown in FIG. 2, the menu icon 31, the submenu open icon 32L, the display switching icon 33, the widening icon 34, and the detailing icon 35 are placed at the same positions on the display unit 21 as the respective icons. A reaction area of the same size is set.

Assume that the user touches the submenu open icon 32L in FIG. 2, for example. A user is, for example, a vehicle driver. When the user touches the touch panel 22 , the operation detection unit 12 detects the position where the user touches the touch panel 22 based on a physical reaction such as a change in current or capacitance caused by touching the touch panel 22 . If the position touched by the user is within the reaction area corresponding to the submenu open icon 32L, the operation detection unit 12 detects that the submenu open icon 32L has been operated. Touching any icon by the user on the touch panel 22 is referred to as pressing an icon.

When the submenu open icon 32L is pressed, the operation response control unit 13 shifts the display mode of the icons on the display unit 21 as shown in FIG. In the icon display setting section 15, how the display mode of each icon is to be changed when the icon is pressed is set. When the submenu open icon 32L is pressed, the operation response control unit 13 instructs the icon display setting unit 15 to change the icon display mode. The display control unit 11 displays the icons after the transition on the map.

In the example shown in FIG. 3, instead of the submenu open icon 32L, a submenu close icon 32S for hiding the submenu is displayed, and submenu icons 381 to 385 are displayed on the left side thereof. The submenu close icon 32S is described as "display S". For example, the submenu icon 381 is an icon for registering your home, and the submenu icon 382 is an icon for searching for facilities around the current position. Any icon can be set as the submenu icons 381-385.

In FIG. 3, when the user presses the submenu close icon 32S, the operation response control unit 13 controls the display mode of the icons on the display unit 21 to return to that shown in FIG.

In FIG. 2 or 3, if the user presses the widening icon 34, the operation detection unit 12 detects the pressing of the widening icon 34, and the operation response control unit 13 displays on the display unit 21. The display control unit 11 is instructed to increase the scale of the map to widen the map. If the user presses the detailed icon 35, the operation detection unit 12 detects the pressing of the widening icon 34, and the operation response control unit 13 lowers the scale of the map displayed on the display unit 21. to instruct the display control unit 11 to refine the map.

Next, a specific operation of the operation input device 10 for reducing the occurrence of erroneous operations of icons that are likely to cause erroneous operations will be described. In FIG. 1, the pressed position storage unit 17 stores pressed positions when the user presses each icon. The pressed position storage unit 17 may be a ring buffer that stores a predetermined number of pressed positions of each icon and overwrites the oldest pressed position with the latest pressed position.

FIGS. 4A to 4C conceptually show multiple pressing positions when the menu icon 31, the submenu open icon 32L, and the display switching icon 33 are pressed, respectively. Each white circle shown in FIGS. 4A to 4C indicates a pressed position.

As shown in FIG. 4A , the positions where the menu icon 31 is pressed multiple times are concentrated in the center of the menu icon 31 . Assuming that the navigation device is located on the left side of the driver, the menu icon 31 is located near the driver and is located in the lower right corner of the display unit 21, where it is easy to determine the pressing position with the finger. Less and easier to concentrate in the center.

As shown in FIG. 4B, the positions where the submenu open icon 32L is pressed multiple times are biased toward the left side of the submenu open icon 32L. The submenu open icon 32L is adjacent to the left side of the menu icon 31, and the user is conscious not to press the menu icon 31, so it tends to be biased to the left of the center.

As shown in FIG. 4C , the positions where the display switching icon 33 is pressed a plurality of times are biased downward with respect to the center of the display switching icon 33 and spread in the horizontal direction. Since the display switching icon 33 is located in the upper left corner, it is likely to be biased downward with respect to the center.

4A to 4C are examples of icon pressing positions. The actual pressing position depends on the positional relationship between the driver and the navigation device, whether the operator of the navigation device is the driver or an occupant sitting in the front passenger seat, and the individual difference of each operator. It is determined by various factors such as. Therefore, it is not determined whether or not the pressed positions of the icons are concentrated in the center, in which direction if they are biased, and in which direction if they spread out.

The pressed position distribution detection unit 18 detects the distribution of pressed positions of each icon stored in the pressed position storage unit 17 . By detecting the distribution of the pressed positions by the pressed position distribution detection unit 18, it is possible to determine whether the pressed positions of the icons are concentrated in the center, and whether the pressed positions are concentrated in the upward direction, the downward direction, the left direction, or the right direction. It can be determined whether or not there is, and whether or not it spreads in the vertical direction or the horizontal direction.

The pressed position distribution detection unit 18 may detect the distribution of pressed positions when the pressed position storage unit 17 stores a predetermined number of pressed positions for one icon. The predetermined number is ten, for example. As an example, the pressed position distribution detection unit 18 may calculate the deviation of multiple pressed positions from the center of the icon as a deviation, and quantify the distribution of the pressed positions.

As another example, the pressed position distribution detection unit 18 may detect the distribution of pressed positions as follows. The icon 39 shown in FIG. 5A is any of the menu icon 31 to detail icon 35, or the submenu icons 381 to 385, or any icon different from these icons. It is assumed that the reaction area of icon 39 is the same size as icon 39 .

The pressed position distribution detection unit 18 detects how the multiple pressed positions are distributed in nine divided regions 391 to 399 obtained by dividing the icon 39 (response region) into three in the horizontal direction and three in the vertical direction. Count the number of dolphins. For example, it is assumed that the pressed positions obtained by pressing 10 times are counted. As shown in FIG. 5B, in the example shown in FIG. 5A, the pressed position distribution detection unit 18 presses the area 394 six times, presses the areas 395 and 396 once each, presses the area 397 twice, and presses the area 397 twice. area 391 to 393, 398, and 399 are counted as 0 times.

In this case, the pressed position distribution detection unit 18 can determine that the multiple pressed positions are concentrated in the center in the vertical direction, but are biased to the left side in the horizontal direction. If the pressed position indicated by the white circle straddles the boundary of the areas 391 to 399, the pressed position should be located in the area where the center of the pressed position is located.

In this way, the pressed position distribution detection unit 18 detects the distribution of the pressed positions of each icon stored in the pressed position storage unit 17, and determines the bias or spread of the pressed positions based on the distribution of the pressed positions. Various methods are conceivable. The method of detecting the distribution of the pressed positions and the method of determining the bias or spread of the pressed positions based on the distribution of the pressed positions are not limited to the method of using the quantification by the deviation.

In the examples shown in FIGS. 4A to 4C and 5A, even if a position outside the icon and out of the reaction area is pressed, the pressed position out of the reaction area is stored in the pressed position storage unit 17 as the pressed position. Not remembered. Even if a position outside the icon (response area) is pressed, if it is considered that the user intended to press the icon, the pressed position outside the reaction area is stored in the pressed position storage unit as follows. 17 may be stored as a pressed position.

The erroneous operation determination unit 19 determines whether or not an erroneous operation has occurred in which the user intends to press the icon when pressing a position outside the icon (response area) and accidentally presses a position outside the icon. judge. With reference to FIGS. 6A and 6B, an example will be described in which it is determined to be an erroneous operation of pressing a position outside the icon with the intention of pressing the icon even though the position outside the reaction area was pressed. do. 6A and 6B show an example in which the submenu open icon 32L is erroneously operated.

As shown in (a) of FIG. 6A, it is assumed that the user accidentally presses a map that is shifted to the left of the submenu open icon 32L when trying to press the submenu open icon 32L. When the operation detection unit 12 detects pressing of the map, the operation response control unit 13 shifts the display mode of the display unit 21 to the state shown in (b) of FIG. 6A.

The display control unit 11 moves the map so that the position pressed by the user on the map is positioned at the center of the display unit 21, and the cursor 41 and icons indicate that the map can be scrolled vertically or horizontally. 42 to 45 are displayed. The icon 42 is an icon for closing the display mode shown in (b) of FIG. 6A and returning to the display mode shown in (a) of FIG. 6A. An icon 43 is an icon for searching for nearby facilities, and an icon 44 is an icon for registering a point.

Since the user does not intend to shift to the display mode shown in (b) of FIG. 6A, as shown in (c) of FIG. ) returns to the display mode shown in . Furthermore, immediately after that, as shown in (d) of FIG. 6B, the user again presses the submenu open icon 32L.

In this way, after the user presses a position away from any icon, the user presses an icon (for example, icon 42) for closing the display mode after transition within a predetermined time, and then presses the icon for a predetermined time. Suppose you press the icon in In such a case, it can be determined that pressing a position away from the first icon is an erroneous operation intended to press the icon that was pressed later. The predetermined time is preferably a short period of time, for example, about 2 seconds. It is preferable to determine that an erroneous operation has occurred when the pressed position away from the first icon is within a predetermined distance from the subsequently pressed icon.

As shown in FIG. 7, when the erroneous operation determination unit 19 determines that an operation has been performed erroneously, the pressed position storage unit 17 stores the pressed position of the sub-menu open icon 32L at a position outside the first pressed sub-menu open icon 32L. Store as a position. The pressed position distribution detection unit 18 detects the distribution of pressed positions stored in the pressed position storage unit 17, including the pressed positions outside the submenu/open icon 32L, and determines whether or not there is bias in the pressed positions. .

In FIG. 1, when the pressed position distribution detection unit 18 determines that the pressed positions of the icons are biased, the reaction region setting unit 16 expands the reaction region corresponding to each icon in accordance with the biased pressed positions. , displace. FIG. 8A shows a response area 321 obtained by enlarging the response area of the submenu open icon 32L whose pressed position is biased to the left with respect to the center to the left. The reaction area setting unit 16 sets a reaction area 321 enlarged to the left with respect to the submenu open icon 32L.

FIG. 8B shows the response area 322 in which the response area of the submenu open icon 32L, whose pressed position is biased to the left with respect to the center, is displaced to the left. The reaction area setting unit 16 may set the reaction area 322 displaced to the left without enlarging the reaction area with respect to the submenu open icon 32L.

By setting the reaction area 321 or 322 for the submenu open icon 32L by the reaction area setting unit 16, it is possible to reduce the occurrence of erroneous operations of the submenu open icon 32L. If the reaction area is displaced without expanding the reaction area, even if the user presses the icon at a position outside the reaction area, there will be no reaction. Therefore, it is preferable to expand the reaction area.

FIG. 9 shows a response area 331 obtained by enlarging the response area of the display switching icon 33 whose pressed position is biased downward with respect to the center and spreads in the horizontal direction both to the left and right and to the bottom. The reaction area setting unit 16 expands the reaction area downward because the pressed position is biased downward, and further expands the reaction area in the horizontal direction because the pressed position spreads in the horizontal direction. By setting the reaction area 331 for the display switching icon 33 by the reaction area setting unit 16, the occurrence of erroneous operation of the display switching icon 33 can be reduced.

As shown in FIG. 4A, the pressed positions of the menu icons 31 are concentrated in the center, and are not biased in any of the up, down, left, and right directions. That is, almost no erroneous operation occurs when the menu icon 31 is pressed. In such a case, the response area for the menu icon 31 may remain at the same position and size as the default menu icon 31 . Therefore, the reaction area setting unit 16 neither enlarges nor displaces the reaction area for the menu icon 31 .

As described above, according to the operation input device 10, it is possible to reduce the occurrence of erroneous operations of icons that are likely to cause erroneous operations. The pressed position distribution detection unit 18 may detect the distribution of pressed positions and determine only whether or not the pressed positions are biased. That is, the pressed position distribution detection unit 18 does not need to determine whether or not there is a spread of pressed positions. The reaction area setting unit 16 may enlarge or displace the reaction area corresponding to only the bias of the pressed position.

Furthermore, preferred first to third setting examples of icons and reaction areas by the icon display setting unit 15 and the reaction area setting unit 16 will be described. FIG. 10(a) shows a state in which icons 51 to 57 are displayed on the display section 21. FIG. Each reaction area of the icons 51-57 has the same position and size as the icons 51-57. It is assumed that the pressed positions of the icons 51 to 57 are concentrated in the center of each and are not biased in any direction of up, down, left, or right, and that erroneous operations hardly occur.

In such a case, as shown in FIG. 10B, the icon display setting unit 15 replaces the icons 51 to 57 with smaller icons 51s to 57s as a first setting example, and the reaction area setting unit 16 should be at the same position and the same size as the icons 51s to 57s. In this way, the portion of the information such as the map displayed on the display unit 21 that is hidden by the icons 51 to 57 can be reduced.

(a) of FIG. 11A is the same display mode as (a) of FIG. It is assumed that reaction areas 510 and 520 having the same position and size as the icons 51 and 52 are set for the icons 51 and 52, respectively. Assume that the pressed position of the icon 51 is biased downward.

In this case, as shown in (b) of FIG. 11A , the reaction area setting unit 16 enlarges the reaction area 510 of the icon 51 downward to form a reaction area 511 . Then, the reaction area 511 and the reaction area 520 partially overlap. Therefore, as shown in FIG. 11B, the icon display setting unit 15 and the reaction area setting unit 16 move the icon 51 and the reaction area 511 upward, and move the icon 52 and the reaction area 520 downward as a second setting example. By moving, the overlap between the reaction area 511 and the reaction area 520 is eliminated.

The icon display setting unit 15 and the reaction area setting unit 16 do not move the positions of the icon 52 and the reaction area 520, but move only the icon 51 and the reaction area 511 upward to overlap the reaction area 511 and the reaction area 520. may be resolved. The icon display setting unit 15 and the reaction area setting unit 16 move only the icon 52 and the reaction area 520 downward without moving the positions of the icon 51 and the reaction area 511 so that the reaction area 511 and the reaction area 520 overlap. may be resolved. The icon display setting unit 15 and the reaction area setting unit 16 may move at least one of the icon 51 and reaction area 511 and the icon 52 and reaction area 520 .

The icon display setting unit 15 may not move the positions of the icons 51 and 52 and the reaction area setting unit 16 may move the position of the reaction area 511 or 520 . In (b) of FIG. 11A , the reaction region 510 is expanded downward to form the reaction region 511. However, the reaction region 510 is displaced downward, and the reaction region 510 displaced downward and the reaction region 520 are separated. They may partially overlap. In this case as well, the overlap between the reaction regions 510 and 520 should be eliminated. Alternatively, in FIG. 11A(b), if the enlarged reaction area 511 overlaps with the reaction area 520, the enlargement ratio of the reaction area 511 may be changed to the extent that the overlap is eliminated.

FIG. 12(a) shows a state in which small icons 51s to 57s are displayed on the display section 21, similarly to FIG. 10(b). When the large icons 51-57 are replaced with the small icons 51s-57s, some of the map landmarks hidden by the icons 51-57 may appear. In the example shown in FIG. 12(a), by replacing the icon 52 with an icon 52s, a part of the landmark 60 indicating the gas station appears. In such a case, it is preferable to display all of the landmarks because the driver is concerned about the landmarks that are only partially displayed.

Therefore, as shown in FIG. 12B, the icon display setting unit 15 and the reaction area setting unit 16 set the icon 52s and its reaction area so that all of the landmarks 60 appear as a third setting example. For example, move it to the left. The landmarks displayed on the map and the display position of each landmark are stored in the map information storage unit 23 as part of the map information. Therefore, the display control unit 11 can detect that the icon 52s and the landmark 60 overlap each other.

Basic processing executed by the operation input device 10 will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 13 may be processing that a computer program (operation input program) causes a central processing unit to execute when the operation input device 10 is configured by a microcomputer.

In FIG. 13, when the navigation device is powered on, the operation input device 10 displays an icon on the display unit 21 and sets a reaction area corresponding to the icon in step S1. Here, description of map display is omitted. Also, for simplification, an icon is assumed to be an arbitrary icon among a plurality of icons. The operation input device 10 determines whether or not an icon has been pressed in step S2. If the icon is not pressed (NO), the operation input device 10 repeats the process of step S2.

If the icon is pressed in step S2 (YES), the operation input device 10 stores the pressed position in step S3. In step S4, the operation input device 10 determines whether or not a predetermined number of pressed positions are stored for one icon. If the predetermined number of pressed positions are not stored (NO), the operation input device 10 repeats the processing of steps S2 to S4.

If a predetermined number of pressed positions are stored in step S4 (YES), the operation input device 10 detects the distribution of pressed positions in step S5. In step S6, the operation input device 10 determines whether or not the pressed positions are concentrated in the center of the icon. If the pressed positions are concentrated in the center of the icon (YES), the operation input device 10 maintains the size of the reaction area in step S7 and shifts the process to step S12.

If the pressed positions are not concentrated at the center of the icon in step S6 (NO), the operation input device 10 determines whether the pressed positions are upward, downward, leftward, or rightward in step S8. It is determined whether or not it is biased toward. If the pressed position is biased in one direction (YES), the operation input device 10 expands the reaction area in the biased direction in step S9, and proceeds to step S10. If the pressed position is not biased in any direction (NO), the operation input device 10 causes the process to proceed to step S10.

In step S10, the operation input device 10 determines whether or not the pressed positions spread in the vertical direction or the horizontal direction. If the pressed position expands in the vertical direction or the horizontal direction (YES), the operation input device 10 expands the reaction area in the expanding direction in step S11, and proceeds to step S12. If the pressed position does not expand vertically or horizontally (NO), the operation input device 10 shifts the process to step S12.

In step S12, the operation input device 10 determines whether or not the power of the navigation device is turned off. If the power of the navigation device is not turned off (NO), the operation input device 10 repeats the processing of steps S2 to S12. The operation input device 10 always stores the latest predetermined number of pressed positions in step S3, and detects the distribution of the latest predetermined number of pressed positions in step S5.

If the power of the navigation device is turned off in step S12 (YES), the operation input device 10 terminates the process.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the present invention.
