However, the following embodiments do not limit the claimed invention, and all combinations of features described in the embodiments are described below. However, this is not always essential for the solution of the invention.

  FIG. 1 shows an example of the smartphone 100. The smartphone 100 is a mobile phone having the functions of a personal mobile computer. More specifically, the smartphone 100 includes a pressure-sensitive touch screen 140. The smartphone 100 has a function of controlling the movement of display information displayed in the screen of the touch screen 140. The smartphone 100 may be an example of an “information terminal” in the present invention. The touch screen 140 is an example of the “display device” and the “input device” in the present invention, and the display device and the input device are not limited thereto.

  FIG. 2 shows an exemplary configuration of the touch screen 140. The touch screen 140 includes a liquid crystal screen 141 and two plastic films 142 and 143. The plastic film 142 includes two electrodes 142a and 142b (hereinafter collectively referred to as electrodes 142). Similarly, the plastic film 143 includes two electrodes 143a and 143b (hereinafter collectively referred to as electrodes 143). Each plastic film 142, 143 is coated with a metal conductive layer and separated from each other by an air gap. The touch screen 140 is excited by applying a power supply voltage to, for example, the plastic film 142 of the two plastic films 142 and 143. When the touch screen 140 is touched, the two plastic films 142 and 143 come into contact at the touch point, and resistance division occurs along the plastic film 142. The voltage at the touched point becomes a position on the plastic film 142, which is detected by the electrode 143a. Subsequently, the same process is repeated to excite the plastic film 143 and detect the position on the plastic film 143 by the electrode 142a.

  It means that the larger the touch resistance, the weaker the touch pressure.

  The input device is not limited to the contact type, and may be a non-contact type, for example, an infrared light shielding type, an acoustic pulse recognition type, an electromagnetic induction type, or an image recognition type.

  FIG. 3 shows an example of the configuration of the smartphone 100. The smartphone 100 further includes a control unit 110 and a memory 130. The control unit 110 is electrically connected to the memory 130 and the touch screen 140.

  The control unit 110 is one of the members constituting the smartphone 100, and controls the memory 130 and the touch screen 140, and calculates and processes data. More specifically, the control unit 110 executes a program stored in the memory 130, receives data from the memory 130 and the touch screen 140, calculates and processes the data, and outputs the data to the memory 130 and the touch screen 140. To do.

  The memory 130 stores data to be processed by the smartphone 100.

  FIG. 4 shows an exemplary configuration of the control unit 110 of the smartphone 100. The control unit 110 includes a target specifying unit 111, a direction calculation unit 112, a speed calculation unit 113, and a display information control unit 114. Hereinafter, the function and operation of each component will be described.

  The target specifying unit 111 moves based on each pressed position when a plurality of positions on the touch screen 140 are pressed at the same time in a state where a plurality of display information that can be moved is displayed on the screen of the touch screen 140. Specify the display information of the target.

  When a plurality of positions on the touch screen 140 are pressed at the same time, the direction calculation unit 112 determines whether the touch screen 140 is based on the relative relationship between the pressed positions and the relative relationship between the pressed forces at the pressed positions. The direction in which the display information displayed on the screen should be moved is calculated.

  When a plurality of positions on the touch screen 140 are pressed at the same time, the speed calculation unit 113 displays display information displayed in the screen of the touch screen 140 based on the relative relationship of the pressing force at each pressing position. Calculate the speed when moving.

  When a plurality of positions on the touch screen 140 are pressed at the same time, the display information control unit 114 is based on the relative relationship between the pressed positions and the relative relationship between the pressing forces at the pressed positions. Control to move the display information displayed on the screen. For example, the display information control unit 114 controls the display information to move in the direction calculated by the direction calculation unit 112. Further, for example, the display information control unit 114 performs control so that the display information is moved at the speed calculated by the speed calculation unit 113. Further, for example, the display information control unit 114 controls to move the display information of the target specified by the target specifying unit 111.

  FIG. 5 shows an example of an operation flow of the control unit 110 of the smartphone 100. In the following description, an example of scrolling map information while pressing with two fingers on the touch screen 140 will be described.

  For example, map information as shown in FIG. 6 is displayed on the screen of the touch screen 140. The map information displayed on the touch screen 140 can be scrolled in all directions, that is, in any direction. As described above, it is assumed that the points A and B of the touch screen 140 are pressed simultaneously in a state where the map information is displayed on the touch screen 140 as shown in FIG. Point A is located in the lower left part of the screen, and point B is located in the upper right part of the screen.

  Thus, when two places on the touch screen 140 are pressed simultaneously, the target specifying unit 111 of the control unit 110 specifies display information of a target to be moved based on each pressed position (S101). In the case of this example, the display information that can be moved among the display information displayed in the screen of the touch screen 140 is only the map information. Therefore, in this example, the target identification unit 111 performs no processing.

  On the other hand, the direction calculation unit 112 of the control unit 110 scrolls the map information displayed in the screen of the touch screen 140 based on the relative relationship between the pressing positions and the relative relationship between the pressing forces at the pressing positions. The direction to be moved is calculated (S102). For example, the direction calculation unit 112 determines an axis passing through the points A and B as a reference axis that serves as a reference for the direction in which the map information is to be scrolled. That is, the map information scrolls along this reference axis. The direction calculation unit 112 compares the pressing force at the point A with the pressing force at the point B, and maps the direction from the position of the point with the smaller pressing force to the position of the point with the larger pressing force. The information is calculated as the direction to be scrolled. Then, the direction calculation unit 112 sends data indicating the calculated direction to the display information control unit 114.

  On the other hand, the speed calculation unit 113 of the control unit 110 calculates the speed at which the map information displayed in the screen of the touch screen 140 is scrolled based on the relative relationship of the pressing force at each pressing position (S103). ). For example, the speed calculation unit 113 compares the pressing force at the point A with the pressing force at the point B, and calculates the speed when the map information is scrolled according to the magnitude of the difference in the pressing force. . For example, the speed calculation unit 113 calculates the map information so that the speed when scrolling the map information increases as the difference in the pressing force increases. Then, the speed calculation unit 113 sends data indicating the calculated speed to the display information control unit 114.

  The display information control unit 114 of the control unit 110 receives data indicating the direction in which the map information should be scrolled from the direction calculation unit 112 and receives data indicating the speed when the map information is scrolled from the speed calculation unit 113. When received, the map information displayed on the touch screen 140 is controlled to scroll in the direction indicated by the data received from the direction calculation unit 112 at the speed indicated by the data received from the speed calculation unit 113. For example, when the point B is pressed more strongly than the point A, the map information displayed on the touch screen 140 is scrolled in the direction from the point A to the point B.

  Therefore, as shown in FIG. 8, when the user wants to scroll the point C on the map to the point D on the screen, the user can select any two points A and B on the straight line connecting the point C and the point D. What is necessary is just to press. At this time, the user presses the point B stronger than the point A. Then, the point C on the map is scrolled in the direction from the point A to the point B along the straight line connecting the points A and B. Then, the user scrolls the point C on the map to the point D on the screen by releasing the finger from the touch screen 140 when the point C on the map is scrolled to the point D on the screen. be able to.

  Next, an example in which map information is scrolled while pressing on the touch screen 140 with three fingers will be described. For example, assume that points A, B, and C of the touch screen 140 are pressed at the same time as shown in FIG. 9 while the map information is displayed on the touch screen 140.

  As described above, when three places on the touch screen 140 are simultaneously pressed, the target specifying unit 111 of the control unit 110 specifies display information of a target to be moved based on each pressed position (S101). In the case of this example, the display information that can be moved among the display information displayed in the screen of the touch screen 140 is only the map information. Therefore, in this example, the target identification unit 111 performs no processing.

  On the other hand, the direction calculation unit 112 of the control unit 110 scrolls the map information displayed in the screen of the touch screen 140 based on the relative relationship between the pressing positions and the relative relationship between the pressing forces at the pressing positions. The direction to be moved is calculated (S102). For example, the direction calculation unit 112 calculates each of the position vectors P1, P2, and P3 of the point A, the point B, and the point C when the upper left corner of the screen is the base point. Then, the direction calculation unit 112 calculates a position vector P0 of the center of gravity G0 when no pressing force is applied to the points A, B, and C. The position vector P0 of the barycentric point G0 is P0 = (P1 + P2 + P3) / 3. Here, the pressing forces F1, F2, and F3 are applied to the points A, B, and C, respectively. Therefore, the direction calculation unit 112 calculates the position vector Pf of the center-of-gravity point Gf of the points A, B, and C in consideration of these pressing forces. The position vector Pf of the gravity center point Gf is Pf = (F1 × P1 + F2 × P2 + F3 × P3) / (F1 + F2 + F3). Then, the direction calculation unit 112 sends data indicating the calculated position vector Pf of the center of gravity Gf to the speed calculation unit 113 and the display information control unit 114.

  On the other hand, the speed calculation unit 113 of the control unit 110 calculates the speed at which the map information displayed in the screen of the touch screen 140 is scrolled based on the relative relationship of the pressing force at each pressing position (S103). ). For example, when the speed calculation unit 113 receives data indicating the position vector P0 of the centroid point G0 and the position vector Pf of the centroid point Gf from the direction calculation unit 112, the magnitude of the difference between the position vectors P0 and Pf | Pf− In accordance with P0 |, the speed at which the map information is scrolled is calculated. For example, the speed calculation unit 113 calculates the speed when scrolling the map information as the magnitude | Pf−P0 | of the difference between P0 and Pf increases. Then, the speed calculation unit 113 sends data indicating the calculated speed to the display information control unit 114.

  Then, the display information control unit 114 of the control unit 110 receives data indicating the direction in which the map information should be scrolled from the direction calculation unit 112, and the data indicating the speed when the map information is scrolled is the speed calculation unit 113. , The map information displayed on the touch screen 140 is controlled to scroll in the direction indicated by the data received from the direction calculation unit 112 at the speed indicated by the data received from the speed calculation unit 113.

  The processing when these three points are pressed simultaneously can be generalized to the processing when a plurality of points greater than two points are pressed simultaneously. For example, the position vector Pf of the centroid point Gf can be generalized as Pf = Σ (Fi × Pi) / ΣFi.

  FIG. 10 shows an example of a Web page having a frame structure. A web page 141 is displayed on the touch screen 140 in the present embodiment, and map information 142 is displayed as a frame of the web page 141. The Web page 141 can be scrolled up and down on the screen. On the other hand, the map information 142 of the frame of the Web page 141 can be scrolled in any direction in all directions.

  As described above, when two places on the touch screen 140 are simultaneously pressed, the target specifying unit 111 of the control unit 110 specifies display information of a target to be moved based on each pressed position. For example, when point A and point B are pressed as shown in FIG. 11, these pressed positions are positions that deviate from the map information 142 of the frame of the website 141. Therefore, the target specifying unit 111 specifies the Web page 141 as a target to be scrolled.

  Further, for example, when points A and B are pressed as shown in FIG. 12, these pressed positions are positions on the map information 142 of the frame of the Web site 141. Therefore, the target specifying unit 111 specifies the map information 142 of the frame as a target to be scrolled.

  Further, for example, when points A and B are pressed as shown in FIG. 13, there is point A at a position deviated from the map information 142 of the frame of the website 141, and the map information 142 of the frame of the website 141 is displayed. There is a point B at the position. Thus, when a pressing operation is performed across a plurality of display information that can be moved, the target specifying unit 111 specifies display information with a high priority as a target to be moved according to a predetermined priority. For example, when priority is given to the scroll movement of the website 141 including the frame over the display information in the frame, the target specifying unit 111 performs the pressing operation as illustrated in FIG. The site 141 is specified as an object to be scrolled. On the other hand, when priority is given to scrolling the display information in the frame, the target identifying unit 111 scrolls the map information 142 in the frame when a pressing operation as shown in FIG. 13 is performed. Identify as a target.

  In addition, the speed calculation unit 113 in the above-described embodiment calculates the map information so that the speed when scrolling the map information increases as the difference in pressing force increases. In that case, at the start of the scroll movement, the scroll movement may be started when the pressure difference exceeds a certain threshold value, and the scroll movement speed may be increased linearly or stepwise as the pressure difference increases.

  In the above-described embodiment, for example, when two points on the touch screen 140 are pressed, an example of scrolling on a straight line connecting the two points has been described. However, the web site 143 illustrated in FIG. As described above, there is information that can be scrolled only in a predetermined direction. In that case, as shown in FIG. 14, the direction calculation unit 112 can scroll the target even if the points A and B that take a straight line different from the direction that can be scrolled are pressed. The possible direction is calculated as the direction to be scrolled.

  In the above-described embodiment, the case where the display screen is scrolled as the display information has been described. For example, when a movable character is displayed as the display information, the same processing as in the above-described embodiment is performed. By performing this, the character may be moved along the reference axis (for example, see FIGS. 15 and 16). In the case of the movement of the character 144 as well, the reference axis is determined from the relative relationship of the pressing position, and the moving direction and the moving speed including the relative state of the pressing state such as the pressing force and the pressing area are determined in the same manner as the scroll movement of the screen. Can be determined. In that case, the movement range of the character 144 is different from the scrolling movement of the screen. In the case of two-point pressing, the character 144 is not moved beyond the pressing position. In the case of three-point pressing, a triangular shape formed by connecting three points is used. Control such as not moving the character 144 across the sides may be performed.

  Further, for example, when a rotatable rotating body is displayed as the display information, this rotating body may be rotated along the reference axis by performing the same processing as in the above-described embodiment (for example, , See FIGS. Regarding the rotation of the rotator 145, the direction perpendicular to the reference axis calculated by the same means as the screen scroll movement is set as the rotation axis of the rotator 145.

  In addition, when a plurality of positions are moved by being dragged while being pressed, the processing of the above-described embodiment may be executed in a loop whenever the pressing position or the pressing force changes. By performing such processing, the direction and speed of moving the display information can be made to follow the drag operation of the pressing position in accordance with changes in the pressing position and pressing force.

  In the above-described embodiment, the direction and the speed are calculated according to the difference in the pressing force at the plurality of pressing positions. However, the direction and the speed are calculated according to the difference in the pressing area at the plurality of pressing positions. You may make it do.

  In addition, although the smart phone 100 in the above-described embodiment includes the touch screen 140, the display device and the input device may not be integrated as in the touch screen 140. The display device and the input device need only be associated with each other, and may be configured as separate bodies. For example, the touch pad 300 is connected to the terminal 200 provided with the display 250 and a press input is performed by the touch pad 300 (see, for example, FIG. 19), or the terminal 400 provided with the display 450 and the touch pad 460 is used. The touch pad 460 may be used for pressing input (see, for example, FIG. 20).

  As described above, the smartphone 100 according to the present embodiment can move the display information displayed in the screen of the touch screen 140 with an intuitive and easy-to-understand operation compared to known techniques. .

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
