Detailed ways

The first specific embodiment according to the present invention is a touch device. Please refer to FIG. 1 , which shows a schematic diagram of the touch device. As shown in FIG. 1 , the touch device 1 includes a touch panel 10 , a switch unit 12 , an adjustment unit 14 and a determination unit 16 . The touch panel 10 includes a first area 102 and a second area 104 . The information processing device 2 is coupled to the touch device 1 . In practical applications, the surface of the touch panel 10 may have at least two colors or a protruding structure to distinguish the first region 102 from the second region 104 . For example, the first area 102 is displayed in yellow and the second area 104 is displayed in red to facilitate the user to identify the first area 102 and the second area 104 . Next, the interrelationships and functions of the elements included in the touch device 1 will be described in detail.

In fact, the touch panel 10 itself may have elasticity or include elastic components, and the size of the first region 102 and the second region 104 may be set or adjusted individually by the user. Therefore, the function of the adjustment unit 14 is to provide the user with the ability to adjust/define the ranges of the first area 102 and the second area 104 .

For example, the adjustment unit 14 can display an adjustment window on the screen of the information processing device 2, and the user can adjust by changing the boundary position between the first area 102 and the second area 104 of the touch panel 10 in the adjustment window. Range sizes of the first area 102 and the second area 104 . Assuming that the left side of the touch panel 10 is the first area 102, and the right side of the touch panel 10 is the second area 104, when the user moves the boundary between the two areas to the right in the adjustment window, the adjustment unit 14 will touch Make corresponding adjustments on the panel 10. Therefore, the range of the first area 102 will be enlarged while the range of the second area 104 will be relatively reduced.

When the user generates a touch action on the touch panel 10, the touch panel 10 receives the touch action and generates a movement signal. In fact, the touch panel 10 can generate the moving signal by simulating moving a mouse or simulating rolling a mouse wheel.

In practical application, the user can generate the touch action by moving his finger 9 on the touch panel 10 . In addition, as shown in FIG. 1 , the movement signal generated by the touch panel 10 can be transmitted to the information processing device 2 (such as a notebook computer). When the information processing device 2 receives the movement signal, the information processing device 2 can control the displayed mouse cursor or window scrolling according to the movement signal.

For example, if the touch panel 10 simulates the movement of a mouse, when the user's finger 9 touches the touch panel 10 and moves to the left, the touch panel 10 simulates moving the mouse to the left to generate a mouse cursor movement Signal, when the notebook computer receives the mouse cursor movement signal, it will control the mouse cursor displayed on its screen to move to the left.

In addition, if the touch panel 10 simulates the scrolling of the mouse wheel, when the user's finger 9 touches the touch panel 10 and moves downward, the touch panel 10 simulates the downward scrolling of the mouse wheel to generate the scrolling movement of the window When the notebook computer receives the window scrolling movement signal, it will control the scrolling window displayed on its screen to move downward.

The above-mentioned function of controlling the movement of the mouse cursor is the most common function of the touchpad of a general notebook computer. Next, other functions of the touch device 1 will be further discussed. When the touch panel 10 is pressed by an external force, the touch panel 10 will move downward. Since the switch unit 12 is disposed below the touch panel 10, when the first area 102 of the touch panel 10 is pressed so that the touch panel 10 moves down to contact the switch unit 12, the switch unit 12 is activated and A first signal is generated. Actually, the switch unit 12 may be a switch element having elasticity or including an elastic member such as a spring.

Likewise, when the second area 104 of the touch panel 10 is pressed so that the touch panel 10 moves down to contact the switch unit 12 , the switch unit 12 is activated and generates a second signal. It can be seen from the above that whether the switch unit 12 generates the first signal or the second signal depends on whether the first area 102 or the second area 104 of the touch panel 10 is pressed.

In practical applications, the switch unit 12 can generate the first signal/second signal by simulating pressing the left button/right button of the mouse. For example, suppose that when the first region 102 of the touch panel 10 is pressed and moves down to activate the switch unit 12 , the switch unit 12 simulates pressing the left mouse button to generate the first signal. Therefore, when the notebook computer receives the first signal from the switch unit 12, the notebook computer will perform the function corresponding to the action of pressing the left mouse button (for example, click the desktop icon).

On the other hand, suppose that when the second area 104 of the touch panel 10 is pressed to move down to activate the switch unit 12 , the switch unit 12 simulates pressing the right mouse button to generate the second signal. Therefore, when the notebook computer receives the first signal from the switch unit 12, the notebook computer will perform the function corresponding to the action of pressing the right button of the mouse (for example, open the shortcut menu).

In practical applications, since the switch unit 12 is pressed to selectively generate the first signal and/or the second signal according to the first region 102 and/or the second region 104 of the touch panel 10, the touch device 1 generates Before the first signal/second signal, it is necessary to determine whether the first area 102 or the second area 104 is pressed, or whether the first area 102 and the second area 104 are both pressed at the same time. Therefore, the touch device 1 includes a determination unit 16 . The judging unit 16 is coupled to the touch panel 10 and the switch unit 12 . When the touch panel 10 is pressed, the judging unit 16 will judge that the first area 102 and/or the second area 104 of the touch panel 10 is pressed.

Actually, the judging unit 16 may include a plurality of pressure sensing devices. The pressure sensing devices can be respectively disposed in different positions in the first area 102 and the second area 104 of the touch panel 10 . When the sensing device corresponding to the first area 102 senses an external pressure, the judging unit 16 will determine that the first area 102 is pressed. Similarly, when the sensing device corresponding to the second area 104 senses an external pressure, the judging unit 16 will determine that the second area 104 is pressed.

It is worth noting that since the user can change the range size of the first area 102 and the second area 104 of the touch panel 10 through the adjustment unit 14, whenever the adjustment unit 14 adjusts the first area 102 and the second area 104 After the range is adjusted, the adjustment unit 14 will send an adjustment message to the judging unit 16 , the adjustment message includes the adjusted ranges of the first area 102 and the second area 104 . The judging unit 16 can redefine the corresponding relationship between the sensing devices and the first area 102 and the second area 104 according to the updated area range information of the touch panel 10, so as to correctly determine whether the first area of the touch panel 10 is 102 and/or the second area 104 is pressed.

When the touch panel 10 is pressed and moves down to activate the switch unit 12 , the switch unit 12 will selectively generate the first signal and/or the second signal according to the determination result of the determination unit 16 . Assuming the judging result of the judging unit 16 is that both the first area 102 and the second area 104 of the touch panel 10 are pressed simultaneously, the switch unit 12 will simultaneously generate the first signal and the second signal according to the judging result of the judging unit 16 . As mentioned above, the switch unit 12 can generate the first signal/second signal by simulating pressing the left button/right button of the mouse.

Please refer to FIG. 2(A) and FIG. 2(B). FIG. 2(A) and FIG. 2(B) respectively show schematic diagrams of the touch panel 10 before being pressed by an external force and after the external force is removed. As shown in Figure 2(A) and Figure 2(B), when the external force pressing the touch panel 10 is removed, that is to say, once the touch panel 10 originally pressed by the user to contact with the switch unit 12 is released After being turned on, the switch unit 12 will assist the touch panel 10 to return to its original position before being pressed by external force. In fact, the switch unit 12 may include an elastic member (such as a spring) to achieve the above functions.
