Next, an example of a method for operating the touch panel 12 according to the present invention will be described.
FIG. 4 is an explanatory diagram illustrating an example of an input operation in which areas of polygons configured by connecting all contact coordinates are different. White circles in the figure indicate the contact coordinates of the finger on the touch panel 12, and arrows indicate the rotation direction of the hand. The rotational operation performed with the palm or finger closed and the rotational operation performed with the palm or finger opened differ in the area of the polygon formed by connecting all the contact coordinates. Here, by changing the transition display switching speed according to the area of the polygon, even if the same rotation operation is performed, different display switching is performed depending on how the palm or finger is opened. For example, when a small polygon area is detected, the transition display switching speed is increased. When a large polygon area is detected, the transition display switching speed is decreased.

An example of transition display switching will be described. FIG. 5 is an explanatory diagram showing an example of transition display switching.
In addition to page feed display switching that sequentially rotates pages arranged radially in a virtual three-dimensional space as shown in FIG. 1, page feed display scrolling to the left and right as shown in FIG. There is. 5B is a display switching of each side of the cube by rotating the cube in the virtual three-dimensional space, and FIG. 5C is a display switching by turning the page so that the display is switched so as to turn the page of paper. It is. The display switching speeds in FIGS. 5A to 5C are switched depending on how the palm or fingers are opened on the touch panel in FIG.

FIG. 6 is a flowchart showing a procedure of processing for switching the display switching speed in accordance with the area of a polygon formed by connecting all three or more contact coordinates.
Based on the timer signal from the timer 18, the CPU 13 receives the contact coordinate signal output from the coordinate conversion unit 16 at regular time intervals and stores it in the RAM 15. The CPU 13 reads the contact coordinates stored from the RAM 15 at regular time intervals and counts the number of contact coordinates.

CPU13 starts acquisition of the contact coordinate of each finger | toe detected at fixed time intervals, and the memory | storage to RAM15 (step S61).
The CPU 13 reads the contact coordinates from the RAM 15, counts the number of read contact coordinates, and determines whether there are three or more coordinates where the finger is touching on the touch panel 12 (step S62). When the CPU 13 determines that the coordinates of the finger touching on the touch panel 12 are not three or more (step S62: NO), the CPU 13 returns to step S62.
When the CPU 13 determines that there are three or more coordinates that the finger touches on the touch panel 12 (step S62: YES), the CPU 13 calculates a polygonal area having the coordinates of the touching fingers as vertices. (Step S63). The length of each side that is the basis for calculating the area is obtained by calculating the distance between the two point coordinates.

  The CPU 13 reads a reference area stored in advance in the ROM 14 (step S64). The CPU 13 calculates the area ratio of the polygon with respect to the reference area from the polygon area calculated in step S63 and the reference area read from the ROM 14 in step S64 (step S65). The CPU 13 calculates the rotation direction and rotation speed of each finger of the operator from the contact coordinates of each finger acquired in step S61 and the contact coordinates of the most recent finger acquired at regular time intervals (step) S66).

The CPU 13 calculates the display switching direction and speed (step S67). Here, the display switching speed is calculated based on the area ratio and rotation speed obtained above. For example, display switching speed = rotational speed ÷ area ratio. The display switching direction is determined according to the type of transition and the rotation direction. For example, FIG. 1 shows an example in which the zapping display switching direction displayed on the display unit 21 of the receiver 2 and the rotation direction of the finger on the touch panel 12 of the input device 1 substantially coincide.
The CPU 13 generates a control signal based on the calculated display switching direction and speed, and outputs the control signal to the receiver 2 (step S68).

  The CPU 13 reads the contact coordinates from the RAM 15, counts the number of read contact coordinates, and determines whether or not the contact coordinates with which the finger is touching on the touch panel 12 is less than 3 points (step S69). CPU13 returns a process to step S63, when it is judged that the contact coordinate which the finger is contacting on the touch panel 12 is not less than 3 points (step S69: NO). CPU13 complete | finishes a process, when it is judged that the contact coordinate which the finger | toe contacts on the touch panel 12 is less than 3 points (step S69: YES).

FIG. 7 is an explanatory diagram showing calculation of a movement vector related to the rotational sliding operation. That is, FIG. 7 relates to the rotation direction and rotation speed of each finger of the operator calculated in step S66. When each finger slides on the touch panel 12, a movement vector from the contact coordinate of each finger before movement to the contact coordinate of each finger after movement is calculated. FIG. 7 shows the contact coordinates 71a, 72a, 73a, 74a, and 75a of each finger before the movement, and the contact coordinates 71b, 72b, and 73b of each finger after the movement in which the hand rotates clockwise indicated by the white arrow. 74b and 75b.
In this case, the input device 1 includes a movement vector V1 from the contact coordinates 71a to the contact coordinates 71b, a movement vector V2 from the contact coordinates 72a to the contact coordinates 72b, a movement vector V3 from the contact coordinates 73a to the contact coordinates 73b, and a contact. A movement vector V4 from the coordinate 74a to the contact coordinate 74b and a movement vector V5 from the contact coordinate 75a to the contact coordinate 75b are calculated.

The input device 1 calculates the rotation center from the calculated plurality of movement vectors. Further, the input apparatus 1 calculates an average movement vector of the calculated plurality of movement vectors. And the input device 1 calculates | requires a rotation direction from the start point and end point of the average movement vector with respect to the rotation center. In addition, as a movement vector for calculating | requiring a rotation direction, an average movement vector is only an illustration and you may use any of V1-V5.
The rotational speed is a value obtained by dividing the magnitude of the average movement vector by the time before and after the movement.

  Conventionally, the transition display switching speed is based only on the movement speed of the finger. However, in addition to the movement speed of the hand as described above, a real-world metaphor has been introduced, such as fine adjustment of large knobs and quick switching of small knobs by switching the display switching speed according to the degree of palm or finger opening. It becomes possible and a more natural operation is realized.

In the first embodiment, the display switching speed of the transition of the video displayed on the display unit of the receiver according to the difference in the polygonal area formed by connecting all of the plurality of contact coordinates detected on the touch panel 12. The form which switches is demonstrated. However, it is a matter of course that the display switching speed of the transition may be switched according to the difference in the circumference of the polygon formed by connecting all of the plurality of contact coordinates detected on the touch panel 12. . Further, the display switching speed of the transition may be switched according to the difference in the sum of the distances from the center of gravity of the polygon to each vertex.
Alternatively, the degree of palm or finger opening can also be expressed as the degree of concentration or dispersion of the contact points of each finger in the polygonal region on the touch panel 12. For example, the degree of opening of the palm or finger can also be expressed as the point density of contact points per unit area in the polygonal region or the linear density of the circumference of the polygon per unit area. Therefore, for example, the display switching speed of the transition may be switched according to the point density.

In the first embodiment, the display switching speed of the transition is switched based on a polygon formed by connecting all the contact coordinates. However, there are many types of polygons configured by connecting contact coordinates, and any polygon may be specified and the switching process may be executed. For example, when five fingers are placed on the touch panel, there are ₅ C ₃ = 10 triangles composed of the _five contact coordinates, and any triangle may be specified and the switching process may be executed.
Further, the degree of opening of the palm or finger on the touch panel may be represented by the length of a line segment configured by connecting contact coordinates. For example, when five fingers are placed on the touch panel, there are ₅ C ₂ = 10 line segments composed of two contact coordinates, and any line segment is specified, and the length of the specified line segment is determined. The switching process may be executed based on the above.

  In the first embodiment, the area of the polygon is obtained based on the length of each side. Moreover, the length of each side was calculated | required as the distance between two coordinates. However, the method of calculating the length of each side that is the basis for calculating the area of the polygon is, for example, a method of calculating based on the detection resolution of the touch panel 12, a method of calculating based on the resolution of the display unit 11, and the like. Also good.

Embodiment 2
The second embodiment relates to a mode in which the display switching speed of the transition displayed on the display unit 21 of the receiver 2 is switched according to the distance between the two fingers. The second embodiment relates to the implementation of the video display system including the input device 1 as in the first embodiment.

  FIG. 8 is an explanatory diagram illustrating an example of an input operation in which the distance between two points of contact coordinates is different. The white circles in FIG. 8 indicate the contact coordinates of the fingers separated by the distance L, and the arrows indicate the rotation directions of the fingers. For example, when the short distance L is detected, the transition display switching speed is increased, and when the long distance L is detected, the transition display switching speed is decreased.

FIG. 9 is a flowchart showing a procedure of processing for switching the display switching speed of the transition according to the distance between the two points of the contact coordinates.
CPU13 starts acquisition of the contact coordinate of each finger | toe detected at fixed time intervals, and the memory | storage to RAM15 (step S91). The CPU 13 reads the contact coordinates from the RAM 15, counts the number of read contact coordinates, and determines whether there are two contact coordinates on the touch panel 12 (step S92). If the CPU 13 determines that the touch coordinates are not two points on the touch panel 12 (step S92: NO), the process returns to step S92. When the CPU 13 determines that the touch coordinates are two points on the touch panel 12 (step S92: YES), the CPU 13 calculates a distance between the touch coordinates of the two touching fingers (step S93).

  The CPU 13 reads the reference value of the distance between the two points stored in advance in the ROM 14 (step S94). The reference value is a distance between two points when the display switching speed is a predetermined standard speed. The CPU 13 calculates the distance ratio of the distance between the two points with respect to the reference value from the distance calculated in step S93 and the reference value read from the ROM 14 in step S94 (step S95). The CPU 13 calculates the rotation direction and rotation speed of the operator's finger (step S96). Here, the rotation direction and the rotation speed are calculated by using the contact coordinates one stage before from the latest and the latest position on the rotation coordinates having the origin at the midpoint of the contact coordinates of the latest two fingers. The rotation direction is determined from the latest on the rotation coordinates and the moving direction of the contact coordinates one stage before the latest. The rotation speed is calculated from the rotation angle, the rotation time, and the rotation radius. For example, the rotation speed is calculated by dividing the average angular difference of the contact coordinates between the latest and the most recent stage by the fixed time interval for detecting the contact coordinates to obtain the angular speed, and the distance between the contact coordinates calculated in step S93. Multiply by half.

The CPU 13 calculates the display switching direction and speed (step S97). Here, the display switching speed is calculated based on the distance ratio and the rotation speed obtained in steps S95 and S96, respectively. For example, display switching speed = rotational speed ÷ distance ratio. The display switching direction is determined according to the type of transition and the rotation direction. For example, the zapping display switching direction shown on the display unit 21 of the receiver 2 in FIG. 1 is set so that the finger rotation direction in FIG.
The CPU 13 generates a control signal based on the calculated display switching direction and speed, and outputs the control signal to the receiver 2 (step S98).

  The CPU 13 reads the contact coordinates from the RAM 15, counts the number of read contact coordinates, and determines whether there are two contact coordinates on the touch panel 12 (step S99). CPU13 returns a process to step S93, when it is judged that the contact coordinates are two points on the touch panel 12 (step S99: YES). When the CPU 13 determines that the touch coordinates are not two points on the touch panel 12 (step S99: NO), the process is finished.

  Conventionally, the transition display switching speed is based only on the movement speed of the finger. However, by switching the display switching speed according to the distance between two fingers in addition to the finger movement speed as described above, a real-world metaphor, such as fine adjustment of a large knob and quick switching of a small knob. Can be introduced, and more natural operation is realized. In particular, when the knob is thin, the gripping with two fingers is closer to the real image than the gripping with five fingers as in the first embodiment, and the operability is improved.

  The second embodiment is configured as described above, and the other configurations and operations are the same as those of the first embodiment. Therefore, corresponding parts are denoted by the same reference numerals, and detailed description thereof is omitted. .

Embodiment 3
In the third embodiment, when the touch panel 12 is single-touched with a finger, the display switching speed of the transition displayed on the display unit 21 of the receiver 2 is changed according to the size of the figure drawn by moving the detected contact coordinates. According to the switching mode. There are many types of figures drawn by moving contact coordinates, but the area of a circle is treated below. The third embodiment relates to the implementation of the video display system including the input device 1 as in the first embodiment.

  FIG. 10 is an explanatory diagram illustrating an example of an input operation in which the area of a circle drawn by moving the contact coordinates is different. The white circles in FIG. 10 indicate the contact coordinates of the finger pressing the touch panel 12, and the arrows indicate the rotation direction and locus of the finger. In Embodiment 3, when the area of the circle is small, the display switching speed is increased, and when the area of the circle is large, the display switching speed is decreased. Perform the switching process.

FIG. 11 is a flowchart illustrating a procedure of processing for switching the display switching speed of the transition according to the area of the circle drawn by the movement of the contact coordinates.
CPU13 starts acquisition of the contact coordinate of each finger | toe detected at fixed time intervals, and the memory | storage to RAM15 (step S111). Here, the CPU 13 stores the contact coordinates from the last three points in the RAM 15. When the contact coordinates after the fourth point from the start of the program are acquired, the oldest contact coordinates stored in the RAM 15 are cleared and the latest contact coordinates are stored in the RAM 15.

  The CPU 13 reads the latest contact coordinates from the RAM 15, counts the number of read contact coordinates, and determines whether or not the nearest contact coordinate on the touch panel 12 is one point (step S112). When the CPU 13 determines that the latest contact coordinate on the touch panel 12 is not one point (step S112: NO), the process returns to step S112. When the CPU 13 determines that the most recent contact coordinate on the touch panel 12 is one point (step S112: YES), the CPU 13 calculates the area of a circle drawn by the movement of the contact coordinates (step S113). The CPU 13 reads a reference area stored in advance in the ROM 14 (step S114). The reference area is an area of a circle when the display switching speed becomes a predetermined standard speed. The CPU 13 calculates the area ratio of the circle with respect to the reference area from the area of the circle calculated in step S113 and the reference area read from the ROM 14 in step S114 (step S115). The CPU 13 calculates the rotation direction and rotation speed of the operator's finger (step S116).

The CPU 13 calculates the display switching direction and speed (step S117). Here, the display switching speed is calculated based on the area ratio and the rotation speed obtained in steps S115 and S116, respectively. For example, display switching speed = rotational speed ÷ area ratio. The display switching direction is determined according to the type of transition and the rotation direction. For example, the zapping display switching direction shown on the display unit 21 of the receiver 2 in FIG. 1 is set so that the finger rotation direction in FIG.
The CPU 13 generates a control signal based on the calculated display switching direction and speed, and outputs the control signal to the receiver 2 (step S118).

  The CPU 13 determines whether or not the most recent contact coordinate on the touch panel 12 is one point (step S119). When the CPU 13 determines that the latest contact coordinate on the touch panel 12 is one point (step S119: YES), the CPU 13 returns the process to step S113. CPU13 complete | finishes a process, when it is judged that the latest contact coordinate on the touch panel 12 is not one point (step S119: NO).

FIG. 12 is an explanatory diagram illustrating a method of calculating the area of a circle drawn by moving the contact coordinates.
When the operator touches the touch panel 12 with a finger, the center point and radius of the circle to be drawn cannot be determined yet. Accordingly, as shown in FIG. 12A, the center area of the touch panel 12 is set as the center point o1 of the temporary circle, and the distance from o1 to the contact coordinates is set as the radius r1 of the circle, thereby determining the area of the circle.
When the operator is moving a finger on the touch panel 12, contact coordinates are acquired at regular time intervals. Therefore, as shown in FIG. 12B, the area of the circle is determined with the point equidistant from the three nearest points as the center point o2 of the circle and the distance from the nearest contact coordinates to o2 as the radius r2 of the circle.
When the contact coordinates stored in the RAM 15 are two points, the center coordinate of the touch panel 12 is set as the temporary circle center point o1, and the distance from the midpoint of the two contact coordinates to o1 is the radius r1 of the circle. As in FIG. 12A, the area of the circle is determined.

Next, the procedure of the circle area calculation process executed by the CPU 13 in step S113 will be described. FIG. 13 is a flowchart showing the procedure of the area calculation process of the circle drawn by the movement of the contact coordinates.
CPU13 reads a contact coordinate from RAM15 (step S131). Prior to step S113 in which this program is executed, one point of contact coordinates has been confirmed in step S112, and the maximum number of contact coordinates stored in the RAM 15 is three. There may be three types of contact coordinates, 1, 2, and 3 points. The CPU 13 determines whether or not the number of read contact coordinates is three (step S132). When the CPU 13 determines that the number of read contact coordinates is three (step S132: YES), the CPU 13 calculates the center coordinates of the circle (step S133). The center coordinates of the circle are obtained as intersections between two sets of two vertices adjacent to each other in the time series from among the three contact coordinates stored in the RAM 15 at regular time intervals. The CPU 13 sets the distance from the latest contact coordinate to the center of the circle obtained in step S133 as the radius of the circle (step S134).

  When the CPU 13 determines that the number of read contact coordinates is not three (step S132: NO), the CPU 13 determines whether the number of read contact coordinates is two (step S135). If the CPU 13 determines that the number of read contact coordinates is two (step S135: YES), the CPU 13 calculates the coordinates of the midpoint of the read contact coordinates (step S136). The CPU 13 sets the distance from the coordinates of the midpoint calculated in step S136 to the center coordinates of the touch panel 12 as the radius of the circle (step S137).

  If the CPU 13 determines that the number of read contact coordinates is not two (step S135: NO), that is, if the CPU 13 determines that the number of read contact coordinates is one, the touch panel is read from the contact coordinates read in step S131. The distance to the center coordinate of 12 is set as the radius of the circle (step S138).

  The CPU 13 calculates the area of the circle from the radius of the circle set in step S134, step S137, and step S138, respectively (step S139), and ends the process.

The calculation of the rotation direction and the rotation speed executed in step S116 is performed using the two latest contact coordinates.
The rotation direction is obtained from the change in position of the contact coordinates with respect to the origin on the rotation coordinates with the center point obtained in the circle area calculation processing in step S113 as the origin. For example, when the contact coordinates of the two most recent points are moving clockwise as time passes, it is determined that the touch coordinates have moved in the + direction on the touch panel 12 of the display device 1 of FIG.
The rotation speed is obtained by calculating the difference between the angles of the two most recent contact coordinates on the rotation coordinates, dividing the difference between the angles by a fixed time interval for detecting the contact coordinates, and determining the angular speed, and multiplying the angular speed by the rotation radius. To calculate. As the rotation radius, the radius obtained in the circle area calculation process in step S113 is used. However, when the operator touches the touch panel 12 with a finger, the number of contact coordinates is one, and therefore the rotation direction and rotation speed cannot be calculated. Therefore, when the number of contact coordinates stored in the RAM 15 is one point, the rotation direction is set as the default in the clockwise direction. In such a case, the rotation direction is not limited to clockwise, but may be set counterclockwise. Further, when the number of contact coordinates stored in the RAM 15 is one point, a predetermined angular velocity is stored in the ROM 14 in advance, and the radius obtained by the circle area calculation processing in step S113, that is, the predetermined angular velocity, that is, The rotation speed is obtained by multiplying the distance between the center coordinates of the touch panel 12 and the contact coordinates.

Next, the procedure of the calculation process of the rotation direction and the rotation speed executed by the CPU 13 in step S116 will be described. FIG. 14 is a flowchart showing the procedure of the rotation direction and rotation speed calculation process.
CPU13 reads a contact coordinate from RAM15 (step S141). Since the contact coordinates of one point have been confirmed in step S112 before the stage of step S116 in which this program is executed, and the number of contact coordinates stored in the RAM 15 is a maximum of three points, step S141. The number of contact coordinates read in can be 1, 2, or 3 points. The CPU 13 determines whether or not the number of read contact coordinates is two or more (step S142). When the CPU 13 determines that the number of read contact coordinates is two or more (step S142: YES), the CPU 13 counts the number of read contact coordinates, and the number of read contact coordinates is either two or three. A flag that makes it possible to determine whether or not is set (step S143).

  CPU13 calculates | requires the rotation direction of a contact coordinate with respect to the center point of the circle calculated | required by the area calculation process of the circle of step S113 (step S144). Here, referring to the flag, when the number of read contact coordinates is 3, the CPU 13 uses the center coordinates obtained in step S133 as the origin of the rotation coordinates, and the read contact coordinates are 2 points. In this case, the midpoint obtained in step S136 is used as the origin of the rotational coordinates. The CPU 13 calculates the rotation speed from the rotation angle, rotation time, and rotation radius obtained from the two most recent contact coordinates (step S145), and ends the process. That is, the angular velocity is obtained by dividing the difference between the angles of the two most recent contact coordinates by a fixed time interval of contact coordinate detection, and the angular velocity is multiplied by the radius set in step S134 or step S137 to calculate the rotational velocity. Here, referring to the flag, when the number of read contact coordinates is 3, the CPU 13 uses the radius of the circle set in step S134 as the rotation radius, and the read contact coordinates is 2 points. In this case, the radius of the circle set in step S137 is used as the rotation radius.

  If the CPU 13 determines that the number of read contact coordinates is not two or more (step S142: NO), that is, if the CPU 13 determines that the number of read contact coordinates is one, the rotation direction is set to the default clockwise. (Step S146). This default setting may be counterclockwise. The CPU 13 reads a predetermined angular velocity determined in advance from the ROM 14, multiplies this angular velocity by the radius of the circle obtained in step S138 of the circle area calculation processing, calculates the rotational speed (step S147), and ends the processing.

  Conventionally, the transition display switching speed is based only on the movement speed of the finger. However, in addition to the finger movement speed as described above, a real-world metaphor has been introduced that allows fine adjustment of large knobs and quick switching of small knobs by switching the display switching speed according to the area of the circle drawn by the finger. It becomes possible and a more natural operation is realized. In particular, the third embodiment can be implemented on the touch panel 12 that cannot detect multi-touch and can detect only a single touch.

  In the third embodiment, the case where the operator simply touches the finger with the touch panel and has not yet drawn a circle is handled (for example, FIG. 12A, step S138 in FIG. 13, step S138 in FIG. 14). Step S146, Step S147). This is because when no process is executed even though the finger touches the touch panel 12, the operator is not questioned. Therefore, when the operator merely touches the touch panel with the finger, a mode in which no processing is executed may be used.

  In Embodiment 3, the area of a circle drawn by one finger was calculated using the contact coordinates of the most recent 1 to 3 points. However, by storing four or more contact coordinates in the RAM, the area of a circle drawn by one finger may be calculated using four or more contact coordinates.

In Embodiment 3, the example in which the display switching speed of the transition is switched based on the area of a circle drawn by one finger moving on the touch panel has been described. However, the display switching speed of the transition may be switched based on the area of a circle drawn by a plurality of fingers. A circle is a special case of an ellipse with an eccentricity of zero, and a figure drawn by one or more fingers may be an ellipse.
A mode for switching the display switching speed of the transition based on the length of the trajectory drawn by one or more moving fingers, the circumference of the ellipse, the length of the arc, the circumference of the sector, the area of the sector, or the area of the ellipse, etc. It may be.
Furthermore, the figure drawn by one or more moving fingers is not limited to an ellipse, a circle, and an arc, but may be a straight line, a triangle, a quadrangle, or the like. The transition display switching speed may be switched according to the length, area, circumference, etc. of these figures.

  The third embodiment has the above-described configuration, and the other configurations and operations are the same as those of the first embodiment. Therefore, corresponding parts are denoted by the same reference numerals and detailed description thereof is omitted. .

  In the first to third embodiments, the example in which the display switching speed of the transition is switched based on how to place a plurality of fingers on the touch panel or the area of a circle drawn by one finger has been described. However, the transition branching process is not limited to the switching of the display switching speed, but is various. Therefore, the present invention is not limited to the first to third embodiments, and can be implemented in various transition branch processes. For example, when there are major classification, middle classification, small classification, etc. as display items, by selecting a favorite classification group based on how to place a plurality of fingers on the touch panel or the area of a circle drawn by one finger Alternatively, an item may be easily selected from a rough selection to a detailed selection by searching the classification group at a favorite speed.

In the first to third embodiments, the rotation speed is calculated from the movement vector corresponding to the rotational movement of the finger or the difference in the angle of the contact coordinates. However, the movement vector that is the basis for calculating the rotation speed is not limited to the rotation movement of the finger, but may be a movement vector related to the translation movement of the finger. FIG. 15 is an explanatory diagram illustrating an example of an input operation in which the distance between two points of contact coordinates is different. FIG. 16 is an explanatory diagram illustrating an example of an input operation in which the lengths of the straight lines drawn by the movement of the contact coordinates are different. For example, FIG. 8 shows an example of switching the display of the transition displayed on the display unit of the receiver by the rotation of two fingers, but the display switching is performed by the translational movement of two fingers as shown in FIG. It may be a mode for executing the processing. Further, as shown in FIG. 16, the display switching process may be executed by translation of one finger. Similarly, the finger operation in FIG. 4 may be a translation operation. In this case, the movement direction and the translational movement speed are calculated from the movement vector obtained by the translational movement of the finger. The display switching direction is obtained from the movement direction of the movement vector.
The display switching speed is obtained from, for example, translational movement speed / distance ratio. Here, the distance ratio is a value obtained by dividing the distance between two fingers by a predetermined reference value in the example of FIG. When the finger operation in FIG. 4 is a translation operation, the display switching speed = the translational movement speed / the area ratio, which is obtained by dividing the area of the polygon formed by connecting the finger contact coordinates by the predetermined area. Value.
When the operation amount is input using a virtual slide bar on the screen, the translation operation of the finger on the touch panel is a natural operation for the operator.

In the first to third embodiments, the embodiment in which the input device and the external device are separated has been described. However, the present invention can be implemented in many electrical devices that execute the switching process. Therefore, the input device may be in a form included in an electric device including an operation unit having an input surface, such as a receiver, a mobile phone, a game machine, a PC, a facsimile, a copy machine, and a refrigerator. In such a case, the calculation of the display switching direction and the display switching speed may be performed by a configuration unit corresponding to the input device, or a configuration unit other than the configuration unit corresponding to the input device.
An operation unit having an input surface is installed in the electric device, and the electric device includes detection means for detecting contact coordinates on the input surface. The electric device may have means for switching processing according to a combination of a plurality of contact coordinates or a size of a figure drawn by moving one or a plurality of contact coordinates.
For example, in a case where a touch panel is installed in a refrigerator and a virtual temperature adjustment dial knob on the touch panel is turned, as shown in FIG. 4, the fine adjustment and the quick adjustment are switched according to the degree of the palm or finger opening. There may be. Further, for example, an embodiment in which a touch panel is installed in a copier and the display switching speed of the magnification display for changing the copy magnification is switched according to the opening degree of two fingers as shown in FIG. Alternatively, for example, a touch panel may be installed on the facsimile, and the address book search speed may be switched according to the area of a circle drawn by one finger.
Furthermore, the embodiment of the present invention may use information obtained from the palm or finger opening degree or the size of the figure drawn by the finger trajectory as a quantitative parameter for switching various processes. Good. For example, an embodiment in which a touch panel is installed on a mobile phone and the type of software such as a camera, browser, mailer, etc. to be activated is switched according to the length of a straight line drawn by one finger may be used. Alternatively, an embodiment in which a touch panel is installed in the video playback device and the video playback speed of the video playback device is switched according to the degree of opening of two fingers may be used.

  In the video display systems of the first to third embodiments, the input device includes a display unit and a display processing unit. However, since the video can be viewed through the screen of the receiver, the display unit and the display processing unit of the input device are not essential. Absent. That is, the input surface of the input device may be a touch pad instead of a touch panel.

  In the first to third embodiments, the case where the touch panel is a plane has been described. However, the shape of the touch panel may be a curved surface.

  In the first to third embodiments, examples in which an input operation on the touch panel is performed with a finger have been described. However, the input operation on the touch panel is not limited to a finger, but may be a stylus such as a palm, a nail, or a pen.

  The above-described first to third embodiments are merely examples of the implementation of the present invention, and the technical scope of the present invention should not be construed in a limited manner. . That is, the present invention can be implemented in various forms without departing from the spirit or the main features thereof.
