Abstract

A touch input device for controlling an electronic device comprises a body, a display layer, a touch layer, a processing unit, and a pressing element. The body comprises a containing portion. The display layer disposed on the body is used for displaying at least one virtual key. The touch layer disposed on the display layer is used for sensing whether a virtual key has been touched by a user and generates a sensing signal. The processing unit disposed in the containing portion electrically connects the touch layer and the display layer. The pressing element is disposed below the touch layer and electrically connected with the processing unit. When user touches any virtual key with a press force larger than a predetermined force, the pressing element is instantly pressed. The processing unit is used for controlling operations of electronic device according to a sensing signal and a pressing signal.

Claims

1. A touch input device, suitable for controlling an electronic device, comprising:

a body, having a containing portion;

a display layer, disposed on the body and used for displaying at least one virtual key;

a touch layer, disposed on the display layer and used for sensing whether the virtual key is touched by a user, thus generating a sensing signal;

a processing unit, disposed in the containing portion and electrically connected to the touch layer and the display layer; and

a pressing element, disposed below the touch layer and electrically connected to the processing unit, wherein when the user touches any virtual key with a press force larger than a predetermined force, the pressing element is instantly pressed to generate a pressing signal;

wherein the processing unit is used for controlling the operations of the electronic device by means of a sensing signal generated by the touch layer and a pressing signal generated by the pressing element.

2. The touch input device according to claim 1, wherein a bottom shell of the body comprises a mobile sensing module, which is used for sensing a reflective light signal on a plane disposed for the touch input device.

3. The touch input device according to claim 1, wherein both the touch layer and the display layer extend to a side wall of the body.

4. The touch input device according to claim 1, wherein the display layer and the touch layer are of arc-curved surface shape.

5. The touch input device according to claim 1, wherein the virtual key is a functional key or a numerical key.

6. The touch input device according to claim 1, wherein the display layer displays several virtual keys, and when a user touches any said virtual key, the pressing element is instantly pressed.

7. The touch input device according to claim 1, wherein the display layer displays several virtual keys, and wherein each said pressing element corresponding to each said virtual key, when a user touches any said virtual key, the corresponding pressing element is instantly pressed.

8. The touch input device according to claim 1, wherein the touch input device controls the electronic device via a wired transmission or a wireless transmission.

9. The touch input device according to claim 1, wherein the touch input device is a mouse.

10. The touch input device according to claim 1, wherein the pressing element generates a sound effect when the pressing element is pressed.
