[2. Operation of display control device]
(2.1 Operation example of display control device)
The operation of the display control apparatus according to the embodiment will be described with reference to FIGS. A case where the display is a map and the display level is a map scroll will be described. In addition to scrolling the display, the display may be enlarged or reduced, or the display may be rotated.

  FIG. 6 is a flowchart illustrating an example of the operation of the display control apparatus 10 according to the embodiment. FIG. 8 is a schematic diagram illustrating an example of how the user's finger touches the detection unit 12. 7, 9, and 10 are schematic diagrams illustrating an example of display on the display unit 11.

  First, the display control apparatus 10 displays information. For example, as shown in FIG. 7, the control unit 16 of the display control device 10 displays a map of the current position on the display panel 11a of the display unit 11 as the home position. A plurality of operation items such as initial settings may be displayed on the display panel 11a of the display unit 11.

  As shown in FIG. 6, the display control device 10 determines whether or not the contact position has moved (move) (step S <b> 1). Specifically, the control unit 16 periodically acquires the coordinate position of the part where the finger touches the touch pad of the detection unit 12 in order to acquire the position information of the contact. Then, the control unit 16 compares the acquired coordinate position with the previously acquired coordinate position to determine whether there is a change. As shown in FIG. 8, the finger 5 is moved in contact with the touch pad of the detection unit.

  The display control device 10 has a function of accepting a user's contact with the touch pad in the detection unit 12 as an example of the contact coordinate input unit 10-1. In addition, the display control device 10 has a function of determining the coordinates of the position touched by the user on the touch pad in the detection unit 12 as an example of the contact position determination unit 10-2.

  Note that the control unit 16 detects the degree of contact and exceeds the predetermined value, and determines that the detection unit 12 has made contact.

  When the contact position is moving (step S1; YES), the display control device 10 determines whether or not the moving amount is a predetermined value or more (step S2). Specifically, the control unit 16 obtains a movement amount between the coordinate position acquired this time and the coordinate position acquired last time. For example, when the threshold value of the predetermined value is 5, the upper left in the figure of the touch pad of the detection unit 12 is (0,0), the lower right is (1000,1000), and the previously acquired coordinates are (100,100), this time acquired If the coordinate is (110, 100), the amount of movement is 10, and the control unit 16 determines that the amount of movement is equal to or greater than a predetermined value.

  When the amount of movement is not equal to or greater than the predetermined value (step S2; NO), the display control device 10 acquires the degree of contact (step S3). For example, the control unit 16 acquires the pressure value (an example of the contact degree) detected by the detection unit 12. A physical pressure value applied to the touch pad of the detection unit 12 is acquired. The range of the physical pressure value is 0-100.

  Next, the display control apparatus 10 determines a contact degree step (step S4). Specifically, the control unit 16 determines a pressure stage defined in advance according to the pressure value based on the acquired physical pressure value. For example, the pressure level is 0 when the physical pressure value is 0 to 9, 1 when the physical pressure value is 10 to 19, and 10 when the physical pressure value is 90 to 100. That is, every tenth physical pressure value increases the pressure level by one.

  On the other hand, when the movement amount is equal to or greater than the predetermined value (step S2; YES), the display control device 10 acquires the degree of contact (step S5). Specifically, the control unit 16 acquires the degree of contact as in step S3.

  Next, the display control apparatus 10 determines whether or not the contact degree increment is equal to or greater than a predetermined value (step S6). For example, the control unit 16 obtains an increase in the physical pressure value acquired this time and the physical pressure value acquired during the previous move. If it is larger than the predetermined value, it is large, and if it is small, it is small. For example, when the increment is less than 10, it is small, and when it is 10 or more, it is large.

  When the increment of the contact degree is equal to or greater than the predetermined value (step S6; YES), the display control device 10 determines the stage of the contact degree (step S7). Specifically, the control unit 16 determines the contact degree stage from the obtained increase in the physical pressure value with respect to the contact degree stage (for example, the pressure stage) previously determined. For example, the pressure stage determined one time before is 3, and when the increment is 10-30, the pressure stage is +1, and when the increment is 30-50, the pressure stage is +2. That is, the increase in the pressure level with respect to the physical pressure value is suppressed as compared with the process in step S4. In this way, the increase in the pressure level can be suppressed only under the condition that the scroll amount changes abruptly (both finger movement amount and pressure value change are large).

  On the other hand, when the contact degree increment is not equal to or greater than the predetermined value (step S6; NO), the display control device 10 performs the process of step S4. That is, every tenth physical pressure value increases the pressure level by one.

  When the amount of movement of the contact portion is smaller than a predetermined value (step S2; NO) or when the degree of contact is smaller than a predetermined value (step S6; NO), the display control device 10 performs step S4. Process.

  As described above, the display control apparatus 10 has a function of measuring the degree of contact with the touch pad in the detection unit 12 as an example of the contact degree measurement unit 10-3.

  Next, the display control apparatus 10 determines a correction value for information display (step S8). Specifically, the control unit 16 determines the scale correction value from the scale of the currently displayed map (information display magnification as an example of the display state of the display unit). For example, if the map is displayed with the largest scale of 0.1 and the smallest is 1, the scale correction varies between 0.1 and 1. By performing this process, when the map display does not require large map scrolling, the increase or decrease of the scroll amount according to the degree of contact is suppressed. The amount of scrolling can be increased or decreased according to the degree.

  Next, the display control apparatus 10 determines the degree of information display (step S9). A display scroll amount and a display scroll direction are determined. Specifically, the control unit 16 determines the scroll amount based on the obtained movement amount, the contact degree stage (for example, the pressure stage), and the information display (for example, the scale correction value). The scroll amount is obtained by a combination of the movement amount and the pressure value. For example, the scroll amount is obtained by the coordinate movement amount × (1 + pressure step × scale correction value). The amount by which the map is scrolled increases in proportion to the amount of coordinate movement and the pressure value.

  And the control part 16 determines a scroll direction from the coordinate position acquired this time and the coordinate position acquired last time. For example, when the previously acquired coordinate is (100, 100) and the currently acquired coordinate is (105, 105), the changed amount is (5, 5), so the lower right 45 ° direction.

  As an example of the display scroll determination unit 10-4, the display control device 10 has a function of determining the scroll amount according to the degree of contact of the contact degree measurement unit 10-3.

  Next, the display control device 10 controls information display (step S10). Specifically, the control unit 16 scrolls the map displayed on the display unit 11 based on the obtained scroll amount and scroll direction. For example, when the finger is moved while touching lightly, when the finger pressure on the detection unit 12 is weak and the scroll amount is small, the scroll of the map is reduced as shown in FIG. On the other hand, when the finger is moved while being strongly pressed, when the finger pressure to the detection unit 12 is strong and the scroll amount is large, the scroll of the map increases as shown in FIG.

  The display control apparatus 10 has a function of controlling the display of the display unit 11 based on the determination result of the display scroll determination unit 10-4 as an example of the screen display unit 10-7.

Next, the display control apparatus 10 determines whether or not it is a release (step S11). Specifically, the control unit 16 detects the degree of contact of the detection unit 12 to determine whether or not the finger has moved away from the detection unit 12, and determines whether or not the detection unit 12 is greater than or equal to a predetermined value.

  In addition, also when the position of a contact has not moved (step S1; NO), it is determined whether it is a release (step S11).

  When it is not determined to be released (step S11; NO), the display control apparatus 10 returns to the process of step S1 and acquires the coordinate position.

  When it determines with release (step S11; YES), the display control apparatus 10 complete | finishes a process, and waits until detection of the next contact.

  As described above, according to the operation according to the embodiment, even if the display unit 11 and the detection unit 12 are separated from each other, the pattern of the degree of contact by the user (for example, the combination of the movement amount and the degree of contact). Based on the above, by controlling the display degree of information on the display unit 11 (for example, the scroll amount), the operation can be adjusted according to the pattern of the degree of contact, so that the user can easily operate the display intuitively.

  Even when viewing a distant place, it is possible to view a map of the target place by simply saving the effort of changing the scale and adjusting the degree of contact such as pressure.

  Further, when the pattern of the degree of contact is based on the movement of the contact portion in the detection unit 12, the input patterns such as moving while touching lightly, moving while touching strongly, moving while changing the strength of touching, etc. are increased. Various display operations can be performed according to the pattern.

  In addition, when the control unit 16 controls the display degree of information in accordance with the amount of movement of the contact portion and the degree of contact, the same can be obtained by combining the amount of movement of the contact portion and the degree of contact. Since the display scroll amount can be changed by the amount of movement, the display operation can be easily adjusted.

  In addition, when the amount of movement of the contact portion is equal to or greater than a predetermined value and the degree of contact is equal to or greater than the predetermined value, the control unit 16 determines that the amount of movement of the contact portion is smaller than the predetermined value or When the change in the degree of information display is reduced compared to the change in the degree of information display when the degree is smaller than a predetermined value, that is, when the degree of information display is suppressed, the scroll amount changes rapidly. The increase in the pressure level can be suppressed only under the condition that both the finger movement amount and the pressure value change are large.

  Further, when the pattern of the degree of contact is a pattern of pressure change applied to the detection unit 12, the pressure on the detection unit 12 makes it easier to operate intuitively.

  Also, by making the pressure value for determining the scroll amount multi-stage, the user's uncomfortable feeling can be largely eliminated by smoothly changing the moving amount.

(2.2 Modification of degree of contact)
Next, modified examples of the degree of contact will be described with reference to FIGS.

  11, 13, and 15 are schematic diagrams illustrating an example of a locus in which the user's finger touches the detection unit 12. FIGS. 12, 14, and 16 are schematic diagrams illustrating an example of a pattern of the degree of contact that the user's finger touches the detection unit 12.

  As shown in FIG. 11, it is assumed that contact is started in the contact area C1 where the user's finger is in contact, moved along the locus t of the contact area C, and released in the contact area C2.

  The control unit 16 of the display control device 10 acquires, from the detection unit 12, the position information of the x coordinate and the y coordinate of the contact area C <b> 1 of the part in contact with the user's finger on the surface of the detection unit 12. The central portion (x1, y1) of the contact area C is set as the coordinate position in step S1.

  And the control part 16 calculates | requires the area and width | variety of the contact area C, and calculates a contact degree in the process of step S3 and step S5.

  In the cycle from step S1 to step S11, the contact area C is detected, and the coordinate position, area, etc. of the contact area C are calculated. The movement amount is obtained, for example, by a change in the coordinate position of the touch area C in one cycle from step S1 to step S11.

  As shown in FIG. 12, it becomes a contact degree change pattern with respect to the movement amount. In the process of step S6, instead of incrementing the contact degree, as shown in FIG. 12, when the contact degree with respect to the movement amount exceeds the threshold θ, the process may proceed to step S7.

  Even if the detection unit 12 does not have a pressure sensor, the same effect can be obtained.

(2.3 Modification of degree of display)
Next, modified examples of the display degree will be described with reference to FIGS.
FIG. 17 to FIG. 20 are schematic diagrams showing modified examples of display on the display unit 11.

  As shown in FIG. 17, the operation item i may be displayed on the display unit 11 instead of the map, and the display degree of the operation item may be controlled.

  First, as shown in FIG. 17, it is assumed that the operation item i and the active operation item ia are arranged on the display panel 11a of the display unit 11 as a home position.

  When the scroll amount is small, the position of the active operation item ia changes as shown in FIG. When the scroll amount is large, the position of the active operation item ia changes as shown in FIG.

  When the display level is scale, as shown in FIG. 20, the number of operation items i may be increased, and the size of the operation item i or the active operation item ia may be reduced.

  Further, as an example of the degree of display, the brightness of the screen, the brightness of the operation item, the size of the displayed character, and the like may be used.

(2.4 Change of display type)
Next, changes in display degree, that is, display scrolling, display enlargement / reduction, display rotation, and the like will be described with reference to FIGS.

  FIG. 21 to FIG. 23 are schematic diagrams showing modifications of the degree of display on the display unit 11.

  First, as shown in FIG. 4, the detection unit 12 displays the scroll area 12a for display, the area 12b for displaying the home position, the area 12c for enlarging / reducing and vertically rotating the display, and the display horizontally. A region 12d for rotation.

  The control unit 16 may determine which of the regions 12a, 12b, 12c, and 12d of the detection unit 12 has been touched in a step before step S1, and may sort the type of display level. .

  When the area 12c of the detection unit 12 is slid vertically by touching the finger 5 lightly without applying pressure, the map may be enlarged or reduced with the center of the screen as the origin (for example, Slide your finger over to zoom in, down to zoom out). When the finger 5 is slid by lightly touching the lower part in the figure in the region 12c, the control unit 16 reduces the map as shown in FIG.

  As an example of the home position determination unit 10-5, the display control device 10 has a function of determining whether to return to the display home position based on the contact position in the contact position determination unit 10-2. In addition, the display control apparatus 10 determines whether the display is enlarged, reduced, or rotated based on the degree of contact of the contact degree measuring unit 10-3 as an example of the display enlargement / reduction rotation determination unit 10-6. It has a function to determine whether.

  When the area 12c of the detection unit 12 is touched with a finger 5 with pressure and is slid vertically with a strength of a predetermined value or more, as shown in FIG. 22, the map is three-dimensional with the center of the screen as the origin. You may make it rotate vertically (a map seen from right above is displayed as if it is seen from the diagonal).

  When the area 12d of the detection unit 12 is slid sideways, the map may be rotated horizontally with the center of the screen as the origin as shown in FIG. Clockwise, if left, clockwise)).

  As described above, when the part of the detection unit 12 that detects contact is divided into predetermined regions, and the control unit 16 changes the type of information display for each region, various screen operations can be performed.

  When the position coordinates of the contact of the detection unit 12 are within the area 12b for displaying the home position, the control unit 16 is displayed at a predetermined scale with the current position as the center, as shown in FIG. The Further, the vibration unit 15 may vibrate by the vibration generating means 10-8 according to the region 12a, the region 12b, the region 12c, and the region 12d of the detection unit 12. The user may be made aware of which region is selected by the vibration pattern.
