Abstract

A method for controlling an electronic device via a touch panel includes defining a relationship between a contact activity and a pointer action, setting activation of a pointer corresponding to a contact activity, synchronizing the contact activity and the pointer action, acquiring analog signals of the contact on the touch panel, converting the analog signals into the digital signals, and controlling the pointer action according to the digital signals. A related system and storage medium with instructions for performance of the method also provided.

Claims

1. An electronic device comprising a display screen and a touch panel, the electronic device comprising:

a definition module configured for defining a relationship between contact activity on the touch panel and pointer action on the display screen, setting an activation of a pointer on the display screen corresponding to the contact activity on the touch panel, and setting a movement speed threshold for controlling a movement speed of the pointer action on the display screen according to a movement speed of the contact activity on the touch panel; and

a synchronization module configured for synchronizing the contact activity on the touch panel and the pointer action on the display screen.

2. The device as claimed in claim 1, wherein the electronic device further comprises a sensor, connected to the touch panel, for acquiring analog signals of contact with the touch screen.

3. The device as claimed in claim 2, further comprising:

an acquisition module configured for acquiring analog signals of the contact on the touch panel;

a signal conversion module configured for converting the analog signals of the contact into digital signals of the contact; and

a control module configured for controlling the pointer action on the display screen according to the digital signals of the contact and controlling the activation of the pointer according to the digital signals of the contact activity on the touch panel.

4. The device as claimed in claim 3, wherein the control module controls the pointer action and the activation of the pointer to provide instructions to an operating system and software applications of the electronic device.

5. The device as claimed in claim 3, wherein the control module further determines if the pointer continues moving according to the speed of the contact activity relative to the movement speed threshold.

6. A computer-implemented method for controlling an electronic device via a touch panel, the electronic device comprising a display screen and the touch panel, the method comprising:

defining a relationship between contact activity on the touch panel and a pointer action on the display screen;

setting an activation of a pointer on the display screen corresponding to the contact activity on the touch panel;

setting a movement speed threshold for controlling a movement speed of the pointer action on the display screen according to a movement speed of the contact activity on the touch panel; and

synchronizing the touch panel and the pointer so as to display the pointer on a corresponding location of the display screen.

7. The method as claimed in claim 6, wherein the electronic device further comprises a sensor, connected to the touch panel, for acquiring analog signals of contact with the touch screen.

8. The method as claimed in claim 7, wherein the method further comprises:

acquiring analog signals of the contact on the touch panel;

converting the analog signals of the contact into digital signals of the contact; and

controlling the pointer action according to the digital signals of the contact and controlling the selection of the pointer according to the digital signals of the contact activity on the touch panel.

9. The method as claimed in claim 8, wherein pointer control further directs the pointer action and the activation, to provide instructions to an operating system and software applications of the electronic device.

10. The method as claimed in claim 8, wherein the pointer control further determines if the pointer continues moving according to the speed of the contact activity relative to the movement speed threshold.

11. A computer-readable medium having stored thereon instructions that, when executed by a computer, cause the computer to perform a method for controlling an electronic device via a touch panel, the electronic device comprising a display screen and a touch panel, the method comprising:

defining a relationship between a contact activity on the touch panel and a pointer action on the display screen;

setting activation of a pointer on the display screen corresponding to the contact activity on the touch panel;

setting a movement speed threshold for controlling a movement speed of the pointer action on the display screen according to a movement speed of the contact activity on the touch panel; and

synchronizing the touch panel and the pointer to display the pointer on a corresponding location of the display screen.

12. The computer-readable medium as claimed in claim 11, wherein the electronic device further comprises a sensor, connected to the touch panel, for acquiring analog signals of contact with the touch screen.

13. The computer-readable medium as claimed in claim 12, wherein the computer-readable medium further comprises:

acquiring analog signals of the contact on the touch panel;

converting the analog signals of the contact into digital signals of the contact; and

controlling the pointer action according to the digital signals of the contact and controlling the selection of the pointer according to the digital signals of the contact activity on the touch panel.

14. The computer-readable medium as claimed in claim 13, wherein pointer control further directs the pointer action and the activation to provide instructions to an operating system and software applications of the electronic device.

15. The computer-readable medium as claimed in claim 13, wherein the pointer control further determines if the pointer continues moving according to the speed of the contact activity relative to the movement speed threshold.
