Abstract

A method and system for controlling an electronic device with an external touch panel are provided. The method includes retrieving applications executed on the electronic device by an interface, displaying user interfaces of the retrieved applications, detecting coordinates of a contacted point on the external touch panel, generating an analog signal in accordance with detection results, converting the analog signal from the touch panel into a digital signal, and outputting the digital signal to the electronic device to synchronize operations of the electronic device with the touch panel.

Claims

1. A touch panel control system operating on a portable electronic device for controlling an electronic device comprising a display, the system comprising:

a retrieve module for retrieving applications information executed on the electronic device by an interface;

a touch panel for displaying user interfaces of the retrieved applications and for detecting coordinates of a contacted point of the touch panel, and for generating an analog signal in accordance with the detection results; and

a conversion module for converting the analog signal from the touch panel into a digital signal and outputting the digital signal to the electronic device to synchronize operations of the electronic device with the touch panel.

2. The system as claimed in claim 1, wherein the system further comprises a control module for sending a sync confirmation in response to receipt of a sync signal indicative of a sync request sent from the electronic device.

3. The system as claimed in claim 2, wherein the control module is configured for sending settings confirmation in response to receipt of screen settings information sent from the electronic device.

4. The system as claimed in claim 3, wherein the control module is further configured for sending the screen settings information to the touch panel so as to display user interfaces of the retrieved applications on the touch panel.

5. The system as claimed in claim 1, wherein the system further comprises a connection module for connecting to the electronic device by the interface.

6. The system as claimed in claim 5, wherein the interface is a BLUETOOTH interface.

7. The system as claimed in claim 5, wherein the interface is a standard Universal Serial Bus (USB) interface.

8. A computer-implemented method for controlling an electronic device comprising a display by an external touch panel, the method comprising:

retrieving applications executed on the electronic device by an interface;

displaying user interfaces of the retrieved applications;

detecting coordinates of a contacted point on the external touch panel;

generating an analog signal in accordance with detection results;

converting the analog signal from the touch panel into a digital signal; and

outputting the digital signal to the electronic device to synchronize operations of the electronic device with the touch panel.

9. The method as claimed in claim 8, wherein before retrieving the applications, the method further comprising:

connecting the electronic device to the touch panel by an interface; and

sending a sync confirmation in response to receipt of a sync signal indicative of a sync request sent from the electronic device.

10. The method as claimed in claim 8, wherein before displaying the user interfaces of the retrieved applications, the method further comprising:

sending settings confirmation in response to receipt of screen settings information sent from the electronic device.

11. The method as claimed in claim 9, wherein the interface is a BLUETOOTH interface.

12. The method as claimed in claim 9, wherein the interface is a standard Universal Serial Bus (USB) interface
