  Hereinafter, a navigation apparatus which is the best mode for carrying out a data processing apparatus according to the present invention will be described with reference to FIGS.

  <Configuration> The configuration of the navigation device 1 according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 1, the navigation apparatus 1 stores an input interface (hereinafter referred to as an input IF) 11 for inputting various data, an HDD 12 (corresponding to a “storage medium”) for storing various data, and various programs. A ROM 13 (corresponding to “control means”), a CPU 14 (corresponding to “control means”) that interprets and executes a program stored in the ROM 13, a RAM 15 that holds data from the input IF 11 and the CPU 14, and the like. An audio processor 16 that controls audio output in accordance with data from the CPU 14, an image processor 17 that controls image output in accordance with data from the CPU 14, a VRAM 18 that holds image data, and an output interface that outputs various data ( (Hereinafter referred to as output IF) 19 and these are connected by a bus. There.

  The input IF 11 includes a GPS receiver 21 that receives GPS data from a satellite, an azimuth sensor 22 that outputs azimuth data corresponding to the azimuth, a speed sensor 23 that outputs speed data corresponding to the velocity, and an object. A touch panel 24 that outputs data related to the contact coordinates in response to the contact is connected.

  As shown in FIG. 2, the touch panel 24 has electrodes 24a arranged in parallel in the X-axis direction and the Y-axis direction, and the contact coordinates P (Xm, Yn) are on the lattice points that are the intersections of the electrodes 24a. Is what you want. In the present embodiment, the contact coordinates P (Xm, Yn) are calculated on the touch panel 24 side.

  The HDD 12 stores map data corresponding to the map image, search data corresponding to the link cost, and the like.

  In the ROM 13, in addition to the navigation program, the CPU 14 functions as a control unit that varies the control of peripheral devices according to the contact area defined by the data related to the contact coordinates output according to the contact with the object on the touch panel 24. A control program is stored.

The output IF 19 is connected to a speaker 31 that outputs sound corresponding to the sound data and a display 32 that displays an image corresponding to the image data. The display 32 is located on the back surface of the touch panel 24 so that the contact coordinates of the touch panel 24 coincide with the display coordinates of the display 32.
<Regarding Operation (Process)> The operation of the navigation apparatus 1 configured as described above will be described with reference to FIGS. As shown in FIG. 3, the CPU 14 interprets the control program stored in the ROM 13 to execute the following process.

  The CPU 14 determines whether or not the data related to the contact coordinates is held in the RAM 15 (step S1). Here, if it is determined that the data related to the contact coordinates is stored in the RAM 15 (No in S1), the CPU 14 ends the process.

  If it is determined in step S1 that the data related to the contact coordinates is held in the RAM 15 (Yes in S1), the CPU 14 calculates the contact center (Xc, Yc) using the data related to the contact coordinates ( Step S2). Here, the contact center is the center of k contact coordinates (Xk, Yk) and is “(Xc, Yc) = (X1 +... + Xk / k, Y1 +... + Yk / k)”. Further, if the touch panel 24 is a resistive film type sensor, one coordinate can be specified by the contact time t on one resistance line. Therefore, if the contact time t is grasped in the range from t−Δt to t + Δt, two adjacent coordinates on one resistance line are detected. In this step, data corresponding to the contact center is held in the RAM 15.

  When the contact center is calculated in step S2, the CPU 14 obtains the contact area S using the data relating to the contact coordinates held in the RAM 15 (step S3). Data corresponding to the contact area S is held in the RAM 15. Below, this process is demonstrated as a contact area calculation process.

  When the contact area calculation process is executed in step S3, the CPU 14 uses the data corresponding to the contact center held in the RAM 15 to determine the direction in which the map screen is scrolled on the display 32 (hereinafter referred to as the scroll direction). (Step S4).

  In the present embodiment, as shown in FIG. 4, when a finger touches the touch panel 24, the scroll direction becomes a direction having a contact center and a screen center as a start point and an end point, respectively (see FIG. 4A). . Further, when the middle finger and the index finger touch the touch panel 24 substantially simultaneously, the scroll direction becomes a direction having a center point of each contact center and a center of the screen as a start point and an end point, respectively (see FIG. 5A).

  When the scroll direction is determined in step S4, the CPU 14 determines the scroll speed V using data corresponding to the contact area S held in the RAM 15 (step S5).

  As shown in FIG. 6, when S <S1, the scroll speed V is “0”. In S1 ≦ S <S2, the relationship between the contact area S and the scroll speed V is proportional to the inclination of (V2−V1) / (S2−S1). Furthermore, in S2 ≦ S, the relationship between the contact area S and the scroll speed V is proportional to (V3−V2) / (S3−S2).

  On the other hand, as shown in FIG. 7, the scroll speed V may be prepared in advance for each range to which the contact area S belongs (see FIG. 7A). Focusing on the fact that the contact area S is proportional to the number k of the contact coordinates P, the scroll speed V may be prepared in advance as a constant for each range to which the number k of the contact coordinates P belongs (FIG. 7B). )).

When the scroll speed is determined in step S5, the CPU 14 outputs control data including the scroll direction determined in step S4 and the scroll speed determined in step S5 to the image processor 17 (step S6). At this time, the image processor 17 draws the map data read from the HDD 12 in the VRAM 18 and transfers the map data drawn in the VRAM 18 to the display 32. The display 32 scrolls and displays the map image in the scroll direction determined in step S4 at the scroll speed determined in step S5. For example, the scroll display state changes from the screen shown in FIG. 4A to the screen shown in FIG. 4C via the screen shown in FIG. 4B. At this time, regarding the speed of scrolling from the screen shown in FIG. 4A to the screen shown in FIG. 4C, the speed in “S2 ≦ S” is larger than the speed in “S1 ≦ S <S2”.
<Regarding the Contact Area Calculation Process> As shown in FIG. 8, the CPU 14 interprets the control program stored in the ROM 13 and executes the contact area calculation process.

  CPU14 calculates the maximum value Xm (max) of the X coordinate (refer FIG. 9) of a contact coordinate using the data regarding the contact coordinate hold | maintained at RAM15 (step S11). Specifically, the process of comparing Xm is repeated for k pieces of data related to the contact coordinates, and the maximum value Xm (max) is obtained.

  When the maximum value Xm (max) is calculated in step S11, the CPU 14 calculates the minimum value Xm (min) of the X coordinate of the contact coordinates using the calculation result in step S11 (step S12).

  When the minimum value Xm (min) is calculated in step S12, the CPU 14 calculates the maximum value Yn (max) of the Y coordinate of the contact coordinates using the data related to the contact coordinates held in the RAM 15 (step S13). ). Specifically, the process of comparing Yn is repeated for k data related to the contact coordinates, and the maximum value Yn (max) is obtained.

  When the maximum value Yn (max) is calculated in step S13, the CPU 14 calculates the minimum value Yn (min) of the Y coordinate of the contact coordinates using the calculation result in step S13 (step S14).

When the minimum value Yn (min) is calculated in step S14, the CPU 14 calculates the area of the ellipse using the calculation results of steps S11 to S14 (step S15). That is, the area of the ellipse is obtained by multiplying the circumference ratio π, the distance | Yn (max) −Yn (min) |, and the distance | Xm (max) −Xm (min) |. In the present embodiment, the contact area S is approximated to an elliptical area, but a polygonal area may be calculated as the contact area S (see FIG. 10). Further, the area of the convex hull (see FIG. 11) may be calculated as the contact area S. Here, the convex hull is the smallest convex polygon including all the points of the set. If the contact coordinates that form the polygon and the convex hull are all lattice points, the area of the polygon and the area of the convex hull are obtained by the Pick's Theorem (Pick'S Theorem), respectively.
<Effects in the Present Embodiment> As described above, according to the present embodiment, the scroll speed V varies depending on the contact area S. Therefore, the scroll speed V can be changed only by the operation of bringing a finger into contact with the touch panel 24.

  According to the present embodiment, since the scroll speed V is proportional to the contact area S, the scroll speed V can be changed only by an intuitive operation of adjusting the contact pressure on the touch panel 24.

  According to the present embodiment, since the proportionality coefficient (inclination) between the scroll speed V and the contact area S is different for each possible range of the contact area S, only an intuitive operation for adjusting the contact pressure on the touch panel 24 is performed. This can be reflected in the scroll speed V.

  According to the present embodiment, since the relationship between the scroll speed V and the contact area S is prepared in advance for each possible range of the contact area S, a time for calculating the scroll speed V from the contact area S can be saved. The scroll speed V can be changed efficiently only by an intuitive operation of adjusting the contact pressure on the touch panel 24.

  According to the present embodiment, since the relationship between the scroll speed V and the number of contact coordinates k is prepared in advance for each possible range of the number of contact coordinates k, the time for calculating the contact area S can be saved, and the touch panel can be saved. The scroll speed V can be changed more efficiently only by an intuitive operation of adjusting the contact pressure with respect to 24.

  According to the present embodiment, since the scroll display is started when the contact area S becomes S1 or more, the start of scrolling can be instructed only by an intuitive operation for adjusting the contact pressure on the touch panel 24.

  As another embodiment, if the correspondence relationship between the control for the peripheral device and the contact area S is stored in the HDD 12 for each user, it is possible to receive the above-described effect with the same device even between users with different finger sizes. it can.

  As another embodiment, the touch panel 24 may be a pressure-sensitive touch panel, and data related to the contact pressure Pr at a specific contact coordinate may be output. At this time, as shown in FIG. 12, the arithmetic expression is such that the scroll speed V is “0” when Pr <Pr1, and the relationship between the scroll speed V and the contact pressure Pr is set when Pr1 ≦ Pr <Pr2 and Pr2 ≦ Pr. It is defined as a proportional relationship of slope (V2-V1) / (Pr2-Pr1) and a proportional relationship of slope (V3-V2) / (Pr3-Pr2). According to this embodiment, even when operating with a hard object such as a ballpoint pen or a stylus, the scroll speed V can be changed only by an intuitive operation of adjusting the contact pressure on the touch panel 24.

As another embodiment, when data relating to the contact pressure Pr at a specific contact coordinate is output, as shown in FIG. 13, the scroll speed V is prepared in advance for each range to which the contact pressure Pr belongs. May be. According to this embodiment, it is possible to save time for calculating the scroll speed V from the contact pressure Pr, and to efficiently change the scroll speed V only by an intuitive operation for adjusting the contact pressure Pr to the touch panel 24.
<Modification> In the above description, an example in which the peripheral device to be controlled is configured by the display 32 has been described. However, other speakers, lights, an air conditioner, a power window, and the like can be similarly implemented.
