Abstract

A time based touch screen input recognition system detects a touch on a touch screen display. The system determines a length of the touch and identifies a function corresponding to the length of touch. The system causes a processing device to implement the corresponding function.

Claims

1. A method, comprising:

detecting, by a processing device, a touch on a touch screen display;

determining a length of the touch;

identifying a function corresponding to the length of the touch; and

causing the processing device to implement the function.

2. The method of claim 1, wherein determining the length of the touch comprises measuring, by a timer, a period of time between a start of the touch and an end of the touch.

3. The method of claim 1, further comprising:

determining a time period corresponding to the length of the touch, wherein determining the time period comprises utilizing a command table storing one or more time period values.

4. The method of claim 3, wherein identifying a function corresponding to the length of the touch comprises utilizing the command table storing one or more functions corresponding to the one or more time period values.

5. The method of claim 4, wherein the one or more time period values and the one or more functions are customizable through a user interface provided on the touch screen display.

6. The method of claim 1, further comprising:

displaying, on the touch screen display, an indication of a function corresponding to a current time period, wherein the current time period comprises a time between a start of the touch and a current time.

7. The method of claim 6, further comprising:

updating the displayed indication to indicate a function corresponding to a subsequent time period when the time between the start of the touch and the current time reaches the subsequent time period.

8. A system comprising:

a processing device;

a touch screen display coupled to the processing device; and

a memory coupled to the processing device, the memory storing a touch screen display driver, executed from the processor and the memory, the touch screen display driver comprising;

a touch sensor module configured to detect a touch on the touch screen display;

a timer configured to measure a length of the touch;

a mapping module configured to identify a function corresponding to the length of the touch; and

a command module configured to cause the processing device to implement the function.

9. The system of claim 8, wherein the mapping module receives a signal from the timer, the signal indicating a period of time between a start of the touch and an end of the touch.

10. The system of claim 8, wherein mapping module utilizes a command table storing one or more time period values and one or more functions corresponding to the one or more time period values to identify a time period corresponding to the length of the touch and the function corresponding to the length of the touch.

11. The system of claim 10, wherein the one or more time period values and the one or more functions are customizable through a user interface provided on the touch screen display.

12. The system of claim 8, wherein the command module is further configured to display, on the touch screen display, an indication of a function corresponding to a current time period, wherein the current time period comprises a time between a start of the touch and a current time.

13. The system of claim 12, wherein the command module is further configured to update the displayed indication to indicate a function corresponding to a subsequent time period when the time between the start of the touch and the current time reaches the subsequent time period.

14. A non-transitory machine readable storage medium storing instructions which when executed cause a data processing system to perform a method comprising:

determining a length of a touch on a touch screen display;

if the length of the touch corresponds to a first time period, causing the data processing system to perform a first function; and

if the length of the touch corresponds to a second time period, causing the data processing system to perform a second function.

15. The storage medium of claim 14, wherein determining the length of the touch comprises measuring, by a timer, a period of time between a start of the touch and an end of the touch.

16. The storage medium of claim 14, wherein the method further comprises:

determining a time period corresponding to the length of the touch by utilizing a command table storing one or more time period values.

17. The storage medium of claim 16, wherein the method further comprises:

identifying a function corresponding to the time period by utilizing the command table storing one or more functions corresponding to the one or more time period values.

18. The storage medium of claim 17, wherein the one or more time period values and the one or more functions are customizable through a user interface provided on the touch screen display.

19. The storage medium of claim 14, wherein the method further comprises:

displaying, on the touch screen display, an indication of a function corresponding to a current time period, wherein the current time period comprises a time between a start of the touch and a current time.

20. The storage medium of claim 14, wherein the method further comprises:

updating the displayed indication to indicate a function corresponding to a subsequent time period when the time between the start of the touch and the current time reaches the subsequent time period.
