(Embodiment)
Exemplary embodiments of a display device, a display method, and a display program according to the present invention are explained in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating an example of a functional configuration of a display device according to an embodiment. The display device 100 is configured such that an operation unit 111 such as a touch panel is provided on the display unit 112. The coordinate position of the display screen of the display unit 112 and the coordinate position of the operation surface of the operation unit 111 are set to the same coordinate by a touch panel control unit (not shown). The display device 100 includes a first reception unit 101, a second reception unit 102, and a determination unit 103.

The first reception unit 101 receives a first operation in which a part of the operation unit 111 is pressed (touched) by the user. The second receiving unit 102 receives a second operation of pressing a plurality of other parts of the operation unit 111 within a reference time after the user has pressed down a part of the operation unit 111 received by the first receiving unit 101.

Here, since the second reception unit 102 receives the second operation within the reference time after the first operation, even if the user once lifts the finger from the operation unit 111, the second reception unit 102 is within the reference time. If another portion of the operation unit 111 is pressed, it is accepted as a second operation. As a result, the user can, for example, perform the operation of setting the display type related to the display in the first operation and the operation of setting the operation amount of the display in the second operation separately in time. The operation can be performed clearly and easily.

The determination unit 103 determines the processing content by the first operation, and determines the change direction and the degree of change of the processing determined by the second operation. For example, when the first operation is an enlargement / reduction of a scale such as a map, the second operation determines the degree of change of the scale for the determined enlargement / reduction. In addition, when the first operation is scrolling a map or the like, the scroll amount is determined in the second operation. The amount of change in the second operation indicates the speed of change in display content per time. The processing content determined by the determination unit 103 and the degree of change with respect to the processing content are output to the touch panel control unit, and the display content of the display unit 112 is controlled.

Also, the determining unit 103 can determine the direction of processing based on the direction of pressing a plurality of fingers by the second operation (the direction in which the fingers are arranged), and can determine the degree of change based on the number of presses.

Further, the determination unit 103 is not limited to determining the degree of change only when the operation amount based on the second operation is operated, that is, when the finger is pressed (touched) on the operation unit 111. That is, when the finger is pressed on the operation unit 111, the degree of change with respect to the processing content is determined to change the actual display content on the display unit 112. Thereafter, when the finger is released from the operation unit 111 Alternatively, the degree of change in processing may be determined again.

FIG. 2 is a flowchart illustrating a processing example of the display device according to the embodiment. The display device 100 waits for a first operation by the user to depress a part of the operation unit 111 by the first reception unit 101 (step S201: No loop). If there is a first operation of the operation unit 111 by the user (step S201: Yes), the process proceeds to step S202.

Next, after the second operation is performed by the second reception unit 102, the second reception unit 102 determines whether the user has performed a second operation on the operation unit 111 within a reference time (step S202). When the second operation is not performed within the reference time (for example, within 1 second) after the first operation (No in step S202), the second reception unit 102 returns to step S201. On the other hand, if a plurality of fingers are pressed at a position different from the first pressed position within a reference time (for example, within 1 second) after the first operation, it is determined that the second operation has been performed (step S202). : Yes).

Next, the determination unit 103 determines the processing content by the first operation (step S203). For example, if the process for enlarging the scale is selected as the process for the map displayed in the first operation, the scale enlargement is determined.

Next, the determination unit 103 determines the degree of change (change amount) with respect to the processing content (scale enlargement of the map) by the second operation. For example, in the second operation, the enlargement ratio of the map scale is determined by the number of fingers (step S204). Specifically, the enlargement ratio is increased as the number of fingers pressing the operation unit 111 is increased. For example, it is determined that the magnification rate is doubled when pressed with two fingers, and the magnification rate is tripled when pressed with three fingers.

According to the embodiment described above, the degree of change at the time of display processing can be changed based on the number of fingers pressing the operation unit. At this time, the user may first remove the finger from the operation unit within the reference time after first determining the processing content by the first operation. By touching the operation unit again with the finger within this reference time, it is detected as a second operation. In this second operation, the degree of change with respect to the processing content determined in the first operation is determined based on the number of fingers. Can be determined. That is, the first post-operation unit may be released, and if it is within the reference time, the determination unit holds the processing content determined by the first operation and accepts the second operation. Makes it possible to separate the operation for determining the processing contents by the first operation and the operation for determining the degree of change by the second operation, thereby providing a clear and easy operability. Can be realized.

Also, the determination unit can determine the processing direction based on the plurality of pressing directions (directions in which fingers are arranged) by the second operation. For example, when the scale of the map is determined by the first operation, and when a plurality of fingers are pressed in order substantially along the right direction on the screen, the determination is made to enlarge the scale by the number of pressed fingers. On the contrary, when a plurality of fingers are pressed in order almost along the left direction on the screen, it is determined to reduce the scale by the number of pressed fingers. At this time, the degree of change (the amount of scale at the time of scaling and the amount of scrolling at the time of scrolling) can be determined by the number of times of pressing a plurality of times.

In addition, the determination unit determines a change amount by pressing a plurality of fingers once on the operation unit in the second operation, changes the display content by the change amount, and then releases the finger from the operation unit. It is possible to determine the degree of change in processing determined including the state. For example, if the number of pressed fingers is reduced by 1 after the operation unit is pressed down by the second operation and displayed as a predetermined enlargement ratio (3 times), the degree of change is reduced by the reduced amount, The scale of the display can be reduced (changed to 2 times).

As described above, according to the embodiment, it is possible to easily determine the processing content and the degree of change with respect to the processing content by simply pressing a plurality of fingers without sliding the finger on the operation unit. The display contents can be controlled with a simple operation.

Next, each embodiment of the present invention will be described. In each embodiment, an example in which the above-described display device 100 is configured using a navigation device 300 mounted on a user's vehicle will be described.

Example 1
FIG. 4 is a diagram for explaining display control for changing the magnification based on a finger operation according to the first embodiment. On the display 313 of the navigation device 300, an input device (touch panel) 311 is provided so as to overlap.

The map data is displayed on the display screen of the display 313, and an operation button (group) 401 for determining the processing content for the display (scale change in the illustrated example) is displayed on the left side of the display screen. Has been. Assume that as one of the operation buttons 401, a magnification enlargement button 401a for enlarging the scale of map data and a magnification reduction button 401b for reducing the magnification are displayed.

The input device (touch panel) 311 detects the pressed coordinate position when the operation button 401 or the like displayed on the display 313 is pressed. For example, the input device 311 is a magnification enlargement operation when the magnification enlargement button 401a is pressed. Is detected.

The display control performed by the navigation device 300 includes the determination of the processing contents described above and the determination of the degree of change with respect to the determined processing contents. These determination processes will be mainly described below.

For example, when an example is described in which the user reduces the scale of the map data, the user first presses the scale down button 401b with, for example, the index finger B as the first operation (the location of touch1 in the figure). Thereby, the touch panel 311 detects pressing of the magnification reduction button 401b, and the CPU 301 determines the magnification reduction as the display processing content. At this time, the map data is reduced to ½ by the first operation.

Next, when the user further changes the reduction ratio, the user further performs a second operation. At this time, the user uses a finger other than the finger (index finger B) pressed in the first operation, to a position other than the position where the operation button (group) 401 is arranged on the touch panel 311 (any part of the map data). ).

Here, when the user presses down on the touch panel 311 other than the pressing index finger B used for the first operation (in this example, the middle finger C) (two touches in the figure), a total of two fingers are pressed and reduced. The magnification can be further changed (for example, 1/3). Thereafter, when the touch panel 311 is further pressed with another ring finger D (the location of touch 3 in the figure), a total of three fingers are pressed on the touch panel 311 to further change the reduction magnification (for example, 1/4 times). . Thereafter, when the touch panel 311 is further pressed with another little finger E (the location of touch 4 in the figure), a total of four fingers are pressed on the touch panel 311 to further change the reduction magnification (for example, 1/5 times). .

Here, if there is a second operation within a reference time (for example, within 1 second) after the first operation, the CPU 301 changes the reduction ratio according to the degree of change according to the number of fingers pressed. . For this reason, even if the finger (index finger B) pressed in the first operation is released, a portion other than the operation button 401 on the touch panel 311 (an arbitrary portion of the map data) is pressed within the reference time (middle finger C in the above example). ) Can be detected as the second operation.

In this way, the degree of processing content (magnification reduction in this example) determined by the first operation can be increased only by increasing the number of fingers to be pressed by the second operation.

When reducing the magnification, the degree of magnification reduction can be increased as the number of fingers pressing the touch panel 311 is increased. Similarly, at the time of magnification enlargement, the degree of magnification enlargement can be increased as the number of fingers pressing down the touch panel 311 is increased.

In the above example, the state in which the touch panel 311 is pressed in the second operation has been described. However, if the number of pressed fingers is reduced, the CPU 301 can perform display control reverse to that in the past. For example, when only one finger (for example, the little finger E) is released after being pressed using the four fingers BCDE shown in FIG. 4, the magnification reduction control up to that point is performed (magnification of 1/4 corresponding to three). To). In this way, the degree of change in the determined processing content can be arbitrarily enlarged or reduced by merely changing the number of fingers that press each finger of one hand on the touch panel 311.

Furthermore, if only one of the fingers is held in the pressed state, the degree of change again can be increased or decreased according to the number of pressed fingers.

At this time, in the second operation, it is only necessary to sequentially press the touch panel 311 at the position of each finger, and a change to the processing content of the display without pressing the determined button position or the like (in the above example, It is possible to easily operate (magnification reduction) without the burden of a finger (for example, it is unnecessary to operate with a finger spread).

(Example 2)
FIG. 5 is a diagram for explaining display control of magnification change based on a finger operation according to the second embodiment. In the second embodiment, the direction of change related to the processing content and the degree of change related to the processing content are determined according to the direction of the finger when pressed in order by the second operation.

In the second embodiment, two buttons (magnification enlargement button 401a and magnification reduction button 401b) as in the first embodiment are not provided on the display 313, and only one magnification change button 401c may be displayed.

Then, as a first operation, the user first presses the magnification change button 401c with, for example, the index finger B (the location of touch 1 in the drawing). In this state, the CPU 301 determines the magnification change as the processing content of the display by the first operation, but has not yet determined the change direction of the processing content (magnification or reduction of the magnification).

Next, the user sequentially presses a plurality of fingers along different directions depending on whether the magnification is enlarged or the magnification is reduced. Thereby, the CPU 301 determines the direction of change of the processing content.

For example, when performing magnification enlargement, the user uses a plurality of fingers other than the finger (index finger B) pressed in the first operation to use a part other than the operation button 401 on the touch panel 311 (any part of the map data). Press.

Here, when the user presses a place close to the magnification change button 401c on the touch panel 311 other than the index finger B being pressed (the middle finger C in this example) used for the first operation (the location of touch 2 in the figure), The CPU 301 determines that the subsequent pressing direction is the right direction, and in this case, determines magnification enlargement as the direction of change in the processing content. The coordinate position within a predetermined distance with respect to the coordinate position of the magnification change button 401c is set as a close place in advance. At the same time, the CPU 301 determines the second processing content assuming that the degree of change in the processing content is doubled, for example.

In this state, if the other ring finger D is pressed down on the touch panel 311 (the location of touch 3 in the figure), a total of three fingers are pressed down on the touch panel 311 (the pressing direction at this time is also the right direction) and enlarged. The magnification can be further changed (for example, 3 times). Similarly, when the touch panel 311 is further pressed with another little finger E (the location of touch 4 in the drawing), the enlargement magnification can be changed to 4 times.

On the other hand, when reducing the magnification, if the user presses a place away from the position of the index finger B being pressed used for the first operation (presses the little finger E at the position of touch 4 in the figure), the CPU 301 In this case, for example, the magnification reduction and the first processing content are determined. At the same time, the CPU 301 determines the second processing content by setting the degree of change in the processing content to, for example, a reduction ratio of 1/2.

In this state, if the portion located on the left side from the little finger E is pressed with another ring finger D (the location of touch 3 in the figure), the reduction ratio can be further changed (for example, 1/3). Similarly, when the touch panel 311 is further pressed down with the other middle finger C located on the left side of the ring finger D (the location of touch 2 in the drawing), the reduction ratio can be changed to ¼.

FIG. 6 is a flowchart illustrating an example of display control for changing the magnification based on a finger operation according to the second embodiment. The magnification change determination process executed by the CPU 301 is mainly described. First, when the CPU 301 detects that the magnification change button 401c is pressed (step S601), the CPU 301 waits for detection of the second pressing position with respect to a place other than the magnification change button 401c (step S602). At this time, as in the second embodiment, the user may release the magnification change button 401c after pressing the magnification change button 401c, or press the magnification change button 401c as in the first embodiment. However, the second press may be performed with another finger.

In step S602, the CPU 301 waits for the next second press for the reference time after the press of the magnification change button 401c. If there is no next pressing within the reference time after pressing the magnification change button 401c (step S602: Case 1), the operation of changing the magnification is canceled (step S603), and the process is terminated.

If the position close to the magnification change button 401c (touch2 in the example of FIG. 5) is pressed within the reference time after the magnification change button 401c is pressed (step S602: Case 2), the CPU 301 expands the magnification change processing. (Step S604). If a position far from the magnification change button 401c (touch 4 in the example of FIG. 5) is pressed within the reference time after the magnification change button 401c is pressed (step S602: Case 3), the CPU 301 reduces the magnification change process. (Step S610).

In the magnification enlargement process on the side of step S604, it is determined whether or not there is a third press within a predetermined time from the second press in step S602 (step S605). If there is no third press (step S605: No), The number of pressed fingers is two, the enlargement magnification is determined to be 2 (step S606), and the process is terminated. On the other hand, if there is a third press (for example, touch 3 in FIG. 5, step S605: Yes), the process proceeds to step S607.

In step S607, it is determined whether there is a fourth press within a predetermined time after step S605 (step S607). If there is no fourth press (step S607: No), the number of pressed fingers is three. Thus, the enlargement magnification is determined to be 3 (step S608), and the process is terminated. On the other hand, if there is a fourth press (for example, touch 4 in FIG. 5, step S607: Yes), the number of pressed fingers is four, the enlargement magnification is determined to be four times (step S609), and the process is performed. finish.

In the magnification reduction process on the side of step S610, it is determined whether or not there is a third press within a predetermined time from the second press in step S602 (step S611). If there is no third press (step S611: No), The number of pressed fingers is two, the reduction ratio is determined to be 1/2 (step S612), and the process ends. On the other hand, if there is a third press (for example, touch 3 in FIG. 5, step S611: Yes), the process proceeds to step S613.

In step S613, it is determined whether there is a fourth press within a predetermined time after step S610 (step S613). If there is no fourth press (step S613: No), the number of pressed fingers is three. Therefore, the reduction ratio is determined to be 1/3 (step S614), and the process is terminated. On the other hand, if there is a fourth press (for example, touch 2 in FIG. 5, step S613: Yes), the number of fingers being pressed is four, and the reduction ratio is determined to be 1/4 (step S615). The process ends.

As described above, in the second embodiment, the processing content in the first operation can be determined at the same time depending on the direction in which the plurality of fingers are pressed during the second operation.

In any of the above-described Examples 1 and 2, there is a delay for the reference time until the second operation is performed after the first operation. At this time, the finger may be once released after the first operation, and it is only necessary to press the finger again within the reference time. Therefore, the determination of the processing content by the first operation and the change of the processing content by the second operation By releasing the finger from the determination of the degree, it becomes possible to perform operation by separating the sense and time. For example, the finger used in the first operation may be used again during the second operation. For example, after the magnification reduction button 401b (touch1) is pressed with the index finger B in the first operation, the index finger B is once released, and the touch2 portion may be pressed again with the index finger B in the second operation.

Example 3
FIG. 7 is a diagram for explaining display control for changing the scroll amount based on a finger operation according to the third embodiment. In the above-described embodiment, the magnification change has been described. In the third embodiment, the scroll amount change will be described. Even in the scroll change, display control related to scrolling (determination of processing content and determination of change amount of determined processing content) is basically performed by pressing a plurality of fingers as in the above embodiment.

As shown in the figure, when the map data is scrolled, there is no button for determining the processing contents. In this case, the CPU 301 displays the ten-hour index X at the center position on the display 313, and when a position away from the index X is pressed, the display screen is displayed so that the pressed position becomes the center position of the display 313. Control to scroll (map data).

Here, control is performed to scroll the display screen (map data) so that the position touched by the finger first becomes the center position of the display 313. In the example of FIG. 7, when the location of touch1 is first pressed with the index finger B, the CPU 301 performs control so that the position of touch1 becomes the center position of the display 313 (corresponding to the first operation). At this time, the scroll speed is set to a normal speed (1 time).

When a plurality of fingers are pressed after the first operation, the CPU 301 determines the second operation, that is, the degree of change (scroll speed) by the number of subsequent fingers. As shown in FIG. 7, when the touch2 part is pressed with the index finger B and the touch2 part is pressed with the other middle finger C as shown in FIG. 7, the press is performed with two fingers. As an operation, the scroll speed is changed (increased) to twice the normal speed. Thereafter, the scroll speed is changed to three times the normal speed when pressed with three fingers including the ring finger D, and the scroll speed is changed to four times the normal speed when pressed with four fingers including the little finger E.

FIG. 8 is a flowchart illustrating a display control example of scroll amount change based on a finger operation according to the third embodiment. The scroll speed change determination process executed by the CPU 301 is mainly described. First, when the CPU 301 detects pressing of the finger on the map data (step S801), the CPU 301 performs control to scroll the display screen (map data) so that the pressed position becomes the center position of the display 313.

At this time, the CPU 301 determines whether or not there is a second finger press within a predetermined time from the first press (step S802). If there is no second press (step S802: No), scrolling is started with the scroll speed set to the normal speed (1 time) (step S803), and the process ends.

In step S802, if there is a second press (touch2 in the example of FIG. 7, step S802: Yes), the process proceeds to step S804. In step S804, it is determined whether there is a third finger press within a predetermined time from the second press (step S804). If there is no third press (step S804: No), the number of pressed fingers is two, scrolling is started with the scroll speed set to twice the normal speed (step S805), and the process ends.

In step S804, if there is a third press (touch3 in the example of FIG. 7, step S804: Yes), the process proceeds to step S806. In step S806, it is determined whether there is a fourth finger press within a predetermined time from the third press (step S806). If there is no fourth press (step S806: No), the number of pressed fingers is three, the scroll speed is set to three times the normal speed, scrolling is started (step S807), and the process ends. If there is a fourth press (touch4 in the example of FIG. 7, step S806: Yes), the number of pressed fingers is four, and scrolling is started with the scroll speed set to four times the normal speed (step S808). The process is terminated.

Also in the third embodiment, the scroll speed can be decreased every time the number of pressed fingers is reduced, and the scroll speed can be increased or decreased in accordance with the increase or decrease of the number of pressed fingers.

Example 4
The fourth embodiment is a modification of the third embodiment. In the fourth embodiment, an example will be described in which the scrolling speed is changed in accordance with the time interval between pressing of a plurality of fingers or the pressing width of each finger.

FIG. 9 is a diagram for explaining display control for scroll change based on finger operation according to the fourth embodiment. First, the scroll speed may be changed based on the interval between adjacent positions pressed by a plurality of fingers. In the second embodiment, the scroll amount at the normal speed (1 time) of pressing at one place (touch 1) and the scroll speed at the time of two fingers (touch 1 and touch 2) are set.

In the fourth embodiment, based on the position pressed by two adjacent fingers (interval L1 between touch1 and touch2), for example, the interval L1 is based on a scroll speed twice that of two fingers (touch1 and touch2). The scroll speed is 1.5 to 2.5 times depending on the situation. As a result, the scroll speed can be continuously varied according to the interval L1 between the two fingers. The scroll speed can also be changed by changing the interval L1 while two fingers are pressed.

Thereafter, when the third finger is pressed, based on the second and third pressing positions (interval L2 between touch 2 and touch 3), the pressing with the three fingers is based on a scroll speed that is three times the normal speed. For example, the scroll speed is set to 2.5 to 3.5 times according to the interval L2.

As described above, when the scroll speed based on the intervals L1 and L2 is changed every time each adjacent finger is pressed, not only the scroll speed is changed only by the adjacent intervals L1 and L2, but the entire interval of the entire pressed finger is changed. The scroll speed may be changed based on the interval L1 + L2.

In each of the embodiments described above, an example of operation using a finger of one hand has been described. However, the number of pressings may be further increased using both hands, and the degree of change in the determined processing content can be further increased and finely controlled. It becomes like this.

And, as described in each embodiment, simply press the finger on the touch panel on the display (no need to adjust the strength of pressing for operations such as sliding and increasing / decreasing the touch area) Determination of processing contents (enlargement / reduction, scroll amount, etc.) and the degree of change of the determined processing contents (magnification and scroll speed) can be easily operated. At this time, the degree of change in processing content (magnification and scrolling speed) can be easily operated by changing the number of fingers to be pressed. Furthermore, it is possible to operate the degree of change of the processing content according to the direction of pressing when the fingers are operated in order, so it is not necessary to consider how to press the finger for the operation, and it is easy and intuitive. It becomes possible to operate.

Moreover, although the said Example demonstrated the structural example which uses a navigation apparatus as a display apparatus, it applies similarly to the electronic device which has a touch panel, for example, a smart phone, a tablet, the display of PC provided with the touch panel, etc. Can do. If the display area or the like of the display is large, the number of fingers that can be pressed increases accordingly, so that it can be operated using both hands.

The display method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
