Abstract

An electronic device includes a display screen and a contact key on a front side and a touch panel on a back side. The electronic device further includes a system configured for controlling the electronic device via contact on the touch panel and contact of the contact key, and displaying corresponding actions via a cursor on the display screen.

Claims

1. An electronic device comprising a display screen and a contact key on a front side of the electronic device, and a touch panel on a back side of the electronic device, wherein the contact key and the touch panel synchronously control actions of a cursor displayed on the display screen through contact of the contact key and contact on the touch panel.

2. The electronic device as claimed in claim 1, further comprising:

a definition module configured for defining a relationship between the contact on the touch panel and a cursor movement on the display screen, and setting an activation of the cursor on the display screen corresponding to the contact of the contact key; and

a synchronization module configured for synchronizing the contact on the touch panel and the contact of the contact key with the corresponding cursor responses on the display screen.

3. The electronic device as claimed in claim 2, further comprising a sensor connected to the touch panel and the contact key, configured for acquiring analog signals of the contact on the touch panel and the contact of the contact key.

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

an acquisition module configured for acquiring first analog signals corresponding to the contact on the touch panel and second analog signals corresponding to the contact of the contact key;

a signal conversion module configured for converting the first analog signals into first digital signals, and converting the second analog signals into second digital signals; and

a control module configured for controlling the cursor movements according to the first digital signals, and controlling the activation of the cursor according to the second signals.

5. The electronic device as claimed in claim 4, wherein the control module controls the cursor movements and the activation of the cursor to provide instructions to activate an operating system and software applications of the electronic device.

6. The electronic device as claimed in claim 1, wherein the electronic device is selected from the group consisting of a portable electronic device, a query terminal device, a point of sale (POS) device, a retail cashier device, and an automatic teller machine (ATM).

7. The electronic device as claimed in claim 1, wherein the display screen is selected from the group consisting of a thin film transistor (TFT) screen, a thin film diode (TFD) screen, a ultra fine bright (UFB) screen, a super-twisted nematic (STN) screen, a color super-twisted nematic (CSTN) screen, a dual-layer super-twisted nematic (DSTN) screen, an organic light emitting diode (OLED) screen, and a field emitting diode (FED) screen.

8. A computer-implemented method for controlling an electronic device, the electronic device comprising a display screen on a front side of the electronic device, the method comprising:

providing a touch panel on a back side of the electronic device and a contact key on a front side of the electronic device;

defining a relationship between contact on the touch panel and a cursor movement on the display screen;

setting an activation of the cursor on the display screen corresponding to contact of the contact key; and

synchronizing the contact on the touch panel and the contact of the contact key with the corresponding cursor responses on the display screen.

9. The method as claimed in claim 8, further comprising:

storing data about the relationships between the contact on the touch panel and the contact of the contact key and the corresponding cursor responses into a memory system of the electronic device.

10. The method as claimed in claim 8, wherein the electronic device further comprises a sensor connected to the touch panel and the contact key, configured for acquiring analog signals of the contact on the touch panel and the contact of the contact key.

11. The method as claimed in claim 10, further comprising:

acquiring first analog signals corresponding to the contact on the touch panel, and/or acquiring second analog signals corresponding to the contact of the contact key;

converting the first analog signals into first digital signals, and/or converting the second analog signals into second digital signals; and

controlling the cursor movements according to the first digital signals, and controlling the activation of the cursor according to the second signals.

12. The method as claimed in claim 11, wherein controlling the cursor movements and the activation provides instructions to active an operating system and software applications of the electronic device.

13. The method as claimed in claim 8, wherein the electronic device is selected from the group consisting of a portable electronic device, a query terminal device, a point of sale (POS) device, a retail cashier device, and an automatic teller machine (ATM).

14. The method as claimed in claim 8, wherein the display screen is selected from the group consisting of a thin film transistor (TFT) screen, a thin film diode (TFD) screen, a ultra fine bright (UFB) screen, a super-twisted nematic (STN) screen, a color super-twisted nematic (CSTN) screen, a dual-layer super-twisted nematic (DSTN) screen, an organic light emitting diode (OLED) screen, and a field emitting diode (FED) screen.

15. An electronic-readable medium having stored thereon instructions that, when executed by an electronic device, cause the electronic device to perform a method for controlling the electronic device, the electronic device comprising a display screen, the method comprising:

providing a touch panel on a back side of the electronic device and a contact key on a front side of the electronic device;

defining a relationship between contact on the touch panel and a cursor movement on the display screen;

setting an activation of the cursor on the display screen corresponding to contact of the contact key; and

synchronizing the contact on the touch panel and contact of the contact key with the corresponding cursor responses on the display screen.

16. The electronic-readable medium as claimed in claim 15, wherein the electronic device further comprises a sensor connected to the touch panel and the contact key, configured for acquiring analog signals of the contact on the touch panel and the contact of the contact key.

17. The electronic-readable medium as claimed in claim 16, wherein the method further comprises:

acquiring first analog signals of the contact on the touch panel, and/or acquiring second analog signals of the contact of the contact key;

converting the first analog signals into first digital signals, and/or converting the second analog signals into second digital signals; and

controlling the cursor movements according to the first digital signals, and controlling the activation of the cursor according to the second signals.

18. The electronic-readable medium as claimed in claim 17, wherein controlling the cursor movements and the activation provides instructions to active an operating system and software applications of the electronic device.
