As shown in FIGS. 4 and 7, in step S16, if the touch of the manipulation object 9 starts in the second region 112, the process proceeds to step S20. Step S20 defines the control window frame 5 on the screen 4. The shape and area of the control window frame 5 may be equal to the shape and area of the touch panel 11 or the scale of the touch panel 11 . More specifically, the arithmetic unit 2 operates according to the coordinates (X _f2 , Y _f2 ) of the manipulation object 9 on the touch panel 11 and the second ratio.

In addition, the control window frame 5 can be displayed or not displayed on the screen 4. The control window frame 5 can be displayed on the screen 4. The user is allowed to grasp his current position, but the user does not need to know the position of the control window frame 5 during operation, so the control window frame 5 can be selected not to be displayed or displayed in a blinking manner.

As shown in FIGS. 5 and 7, if the arithmetic unit 2 determines in step S14 that a plurality of manipulation objects 9a, 9b are on the touch panel 11, the operation proceeds to step S22. In step S22, the application software detecting tool 21 determines the number of the instruction objects 23 of the application software in execution, wherein the instruction object 23 of the embodiment is the image object in FIGS. 5 and 6. If the number of the command items 23 is one, the process proceeds to step S24.

As shown in FIGS. 6 and 7, if the number of the instruction items 23 is plural in step S22, the process proceeds to step S26. Step S26 uses the position of the cursor 9" on the screen 4 as a reference point, and defines the virtual frame 6 on the screen 4. The center point or one of the endpoints of the virtual frame 6 corresponds to the reference point, and the virtual frame 6 It is opposite to one of the command objects 23 in the application. The shape and area of the virtual frame 6 are preferably equal to the shape and area of the touch panel 11, or the size of the area of the object 23 is proportionally scaled.

Next, the arithmetic unit 2 performs operations on the coordinates (X _f4 , Y _f4 ), (X _{f4 '} , Y _{f4 '} ) and the third ratio on the touch panel 11 according to the manipulation objects 9a, 9b. The third ratio is the aspect ratio of the touch panel 11 relative to the virtual frame 6. and . The operation unit 2 calculates the coordinates (X _c4 , Y _c4 ), (X _{c4 '} , Y _{c4 '} ) corresponding to the manipulation object 9 from the touch panel 11 to the virtual frame 6 according to the following formula 3

After the calculation of the coordinate information T3 is completed, the arithmetic unit 2 transmits the coordinate information T3 to the operating system 3. Thereby, the virtual touch elements 9a', 9b' are respectively generated in the virtual frame 6, so that the user can intuitively use the multi-control object on the touchpad 11 to target one of the command objects in the application. Take control.

In addition, the virtual frame 6 may or may not be displayed on the screen 4. Displaying the virtual frame 6 on the screen 4 allows the user to grasp the current position, but the user does not need to know the position of the virtual frame 6 during the operation, so the virtual frame 6 can be selected to be displayed or displayed in a blinking manner. .

A window W (for example, a toolbar of the Windows system) is defined in the right edge region of the touch panel 11. The command window W can be hidden on the right edge of the screen 4. In addition, the touch panel 11 defines a virtual command area 113. The virtual command area 113 is preferably defined in the corresponding area of the touch panel 11 according to the position of the command window W, and at least two boundaries of the virtual command area 113 are aligned with the boundary of the touch panel 11.

According to the foregoing steps S12, S14, S16 and S18, it is first determined that the touch of the manipulation object 9 starts in the first region 111, and the virtual touch member 9' is generated on the screen 4. Next, in step S28, the arithmetic unit 2 determines whether the manipulation object 9 moves from the first region 111 toward the second region 112. If yes, the process proceeds to step S30. In addition, after the determination process of step S28 is completed, the first area 111 and the second area 112 defined by the touch panel 11 are temporarily eliminated, so as to perform a subsequent step procedure. Step S30 opens the command window W corresponding to the screen 4 according to the movement of the manipulation object 9, and proceeds to step S32. At this time, the operating system 3 generates an event signal T4 according to the executed event command, and transmits the event signal T4 to the event receiver 22.

The fourth ratio is an aspect ratio of the virtual instruction area 113 relative to the instruction window W. and . The operation unit 2 calculates a coordinate (X _c5 , Y _c5 ) corresponding to the manipulation object 9 from the virtual instruction area 113 to the virtual frame 6 according to the following formula 4

After the calculation of the coordinate information T3 is completed, the arithmetic unit 2 transmits the coordinate information T3 to the operating system 3. Thereby, the user can execute an instruction or other action on the instruction window W via manipulation of the manipulation object 9 on the virtual command area 113.

At the same time, it is judged whether the manipulation object 9 leaves the touch panel 11. Step S152 compares whether Δt1 is smaller than the first preset time Ta. If Δt1 is less than the first preset time Ta, step S153 starts calculating the time Δt2 when the manipulation object 9 leaves the touch panel 11, and determines whether the manipulation object 9 touches the touch panel 11 again. If the manipulation object 9 touches the touch panel 11 again, step S154 compares whether Δt2 is smaller than the second preset time Tb. If Δt2 is less than the second predetermined time Tb, step S155 determines whether the distance Δd between the secondary touch contacts is less than the threshold value D.
