Abstract

A remote control system includes a remote control device and an electronic device. The remote control device includes an input element, a wireless transmitter to transmit an absolute coordinate signal and a motion signal and a control unit electrically connected to the input element and the wireless transmitter. The electronic device includes a wireless receiver and a display screen. The wireless receiver receives the absolute coordinate signal and the motion signal, and displays the absolute coordinate signal at the display screen via a cursor. When the electronic device does not receive the motion signal, the absolute coordinate signal is not operated on an application program of the electronic device. When the electronic device receives the motion signal, the absolute coordinate signal is operated on the application program.

Claims

1. A remote control system, comprising:

a remote control device including an input element, a control unit and a wireless transmitter, wherein the control unit is electrically connected to the input element and the wireless transmitter, an object is adapted to touch the input element so as to generate an absolute coordinate signal according to an absolute position of the object on the input element, and the wireless transmitter transmits the absolute coordinate signal and a motion signal; and

an electronic device including a wireless receiver and a display screen, wherein the wireless receiver receives the absolute coordinate signal and the motion signal, and the wireless receiver displays the absolute coordinate signal at the display screen via a cursor,

wherein when the electronic device does not receive the motion signal, the absolute coordinate signal is not operated on an application program of the electronic device, and when the electronic device receives the motion signal, the absolute coordinate signal is operated on the application program.

2. The remote control system according to claim 1, wherein the electronic device includes a controller electrically connected between the wireless receiver and the display screen and outputting an image of the application program to the display screen.

3. The remote control system according to claim 1, wherein the remote control device is a mobile phone or a computer.

4. The remote control system according to claim 1, wherein the remote control device further includes a button electrically connected to the control unit to transmit the motion signal to the electronic device.

5. The remote control system according to claim 4, wherein the remote control device further includes a fixing part to fix the button to continuously transmit the motion signal to the electronic device.

6. A remote control method of a remote control system applied to a remote control device and an electronic device, comprising following steps:

receiving a motion at the remote control device and generating an absolute coordinate signal, wherein an object is adapted to touch the input element so as to generate the absolute coordinate signal according to an absolute position of the object on the input element;

transmitting the absolute coordinate signal to the electronic device;

displaying the absolute coordinate signal at the electronic device via a cursor, wherein the absolute coordinate signal is not operated on an application program of the electronic device; and

receiving a motion signal at the remote control device, wherein the remote control device transmits the motion signal to the electronic device to make the absolute coordinate signal is operated on the application program.

7. The remote control method according to claim 6, wherein the remote control device is a mobile phone or a computer.

8. The remote control method according to claim 6, wherein the motion signal is generated when a predetermined motion is received at an input element of the remote control device.

9. The remote control method according to claim 8, wherein the predetermined motion is a double-clicking motion on the input element.

10. The remote control method according to claim 8, wherein the predetermined motion is generated when a pressure or a contacting area on the input element is larger than a threshold.

11. A remote control device, operated with an electronic device, the remote control device comprising:

an input element, adapted for touched by an object and generates an absolute coordinate signal according to the absolute position of the object on the input element;

a wireless transmitter transmitting the absolute coordinate signal and a motion signal; and

a control unit, electrically connected to the input element and the wireless transmitter,

wherein, when the wireless transmitter transmits the absolute coordinate signal and the motion signal to the electronic device, the absolute coordinate signal is operated on an application program of the electronic device.

12. A remote control method, applied to a remote control device with an input element, comprising following steps:

generating a motion signal and an absolute coordinate signal, wherein when an object touch the input element, the absolute coordinate signal is generated according to the absolute position of the object on the input element ; and

outputting the absolute coordinate signal and the motion signal to make the absolute coordinate signal operated on an application program of an electronic device.
