Abstract

Embodiments of methods, apparatuses, devices and systems associated with adjusting for key latency in a handheld device are disclosed. A handheld device may receive a user input, such as a user actuation of a device key. A latency adjusted time of the input may be calculated based, at least in part, on a latency of the handheld device in determining the user actuation of the device key. The latency adjusted time may be used to determine a result of the user input.

Claims

1. A method for use within a handheld electronic device, the method comprising:

determining user actuation of a device key of the handheld electronic device;

determining a latency adjusted time of said user actuation of said device key, said latency adjusted time being based on a latency of said handheld electronic device in determining said user actuation of said device key; and

determining a result of said user actuation of said device key based, at least in part, on said latency adjusted time.

2. The method of claim 1, wherein said handheld electronic device comprises a display, the method further comprising displaying information on said display, said information being based, at least in part, on said result.

3. The method of claim 1, wherein said handheld electronic device comprises a cell phone.

4. The method of claim 1, wherein said result is associated with a game result.

5. The method of claim 2, wherein said displaying information comprises displaying a plurality of objects on said display.

6. The method of claim 5, wherein said displaying information comprises displaying an indicator on said display, wherein said indicator at least in part moves relative to said plurality of objects.

7. The method of claim 6, further comprising determining a game result based, at least in part, on a relative position of said indicator and/or at least one of said plurality of objects at a time associated with a latency adjusted actuation of said device key.

8. The method of claim 1, wherein the handheld electronic device comprises a processor, and wherein said result of said user actuation of said device key is determined using said processor.

9. The method of claim 1, wherein the handheld electronic device comprises a memory having stored thereon a latency associated with said handheld device in determining said user activation of said device key.

10. An apparatus comprising:

a handheld electronic device, comprising;

an input device, and

a processor communicatively coupled to said input device, the processor configured to determine user activation of said input device, to determine a latency adjusted time of said user activation of said input device, said latency adjusted time being based on a latency of said handheld electronic device in determining said user actuation of said input device, and to determine a result of said user activation of said input device based, at least in part, on said latency adjusted time.

11. The apparatus of claim 10, wherein said handheld electronic device further comprises a display, and

wherein said processor is further configured to initiate display of information on said display, said information being based, at least in part, on said result.

12. The apparatus of claim 10, wherein said handheld electronic device comprises a cell phone.

13. The apparatus of claim 10, wherein said result is associated with a game result.

14. The apparatus of claim 11, wherein said display of information comprises a plurality of objects.

15. The apparatus of claim 14, wherein said display of information comprises an indicator, wherein said indictor at least in part moves relative to said plurality of objects.

16. The apparatus of claim 15, wherein said result of said user activation of said input device is associated with a game result based, at least in part, on a relative position of said indicator and/or at least one of said plurality of objects at a time associated with a latency adjusted actuation of said input device.

17. The apparatus of claim 10, wherein the handheld device further comprises a memory having stored thereon a latency associated with determining a user activation of said input device, and wherein the processor is configured to determine said latency adjusted time using said memory.

18. A handheld electronic device comprising:

means for determining user actuation of at least one device key;

means for determining a latency adjusted time of said actuation of said at least one device key, said latency adjusted time being based on a latency of said handheld electronic device in determining said user actuation of said device key; and

means for determining a result of said user actuation of said device key, said result being adjusted based, at least in part, on said latency adjusted time.

19. The handheld electronic device of claim 18, further comprising:

means for displaying information, said information being based, at least in part, on said result.

20. The handheld electronic device of claim 19, wherein said handheld electronic device comprises a cell phone.

21. The handheld electronic device of claim 20, wherein said result is associated with a game result.

22. The handheld electronic device of claim 19, wherein said information comprises a plurality of objects.

23. The handheld electronic device of claim 22, wherein said information comprises an indicator, wherein said indicator, at least in part, moves relative to said plurality of objects.

24. The handheld electronic device of claim 23, wherein said result of said user activation of said device key is associated with a game result based, at least in part, on a relative position of said indicator and/or at least one of said plurality of objects at a time associated with a latency adjusted actuation of said device key.

25. An article comprising:

a storage media comprising instructions configured to operatively enable a handheld electronic device to;

determine user activation of at least one device key of said handheld electronic device;

determine a latency adjusted time of said user activation of said device key, said latency adjusted time being based on a latency of said handheld electronic device in determining said user actuation of said device key; and

determine a result of said user actuation of said device key, said result being based, at least in part, on said latency adjusted time.

26. The article of claim 25, wherein said handheld electronic device comprises a display, and wherein said storage media comprises instructions configured to operatively enable said handheld electronic device to:

display information on said display, said information being based, at least in part, on said result.

27. The article of claim 25, wherein said handheld electronic device comprises a cell phone.

28. The article of claim 25, wherein said result is associated with a game result.

29. The article of claim 26, wherein said information comprises a plurality of objects.
