Abstract

A method and system for changing a display format for information rendered on a handheld device based at least in part on a velocity of the handheld device recognizes that when the velocity of the handheld device that is optimally held by a stationary user in both hands in a horizontal orientation exceeds a predetermined threshold, it is generally indicative that the handheld device is being held by a mobile user in one hand in a vertical orientation. Accordingly, upon determining that the velocity of the handheld device exceeds the predetermined threshold, information rendered on the handheld device is reoriented from a landscape orientation to a portrait orientation so that the information is oriented correctly from the perspective of the mobile user. Thereafter, upon determining that the velocity of the handheld device is below the predetermined velocity threshold, the information rendered on the handheld device is reoriented from the portrait orientation to the landscape orientation so that the information is oriented correctly from the perspective of a stationary user.

Claims

1. A handheld device, comprising:

a user interface; and

a processor communicatively coupled with the user interface, wherein under control of the processor the handheld device reorients information rendered on a display of the user interface based at least in part on a determined velocity of the handheld device.

2. The handheld device of claim 1 further comprising a global positioning system (GPS) receiver communicatively coupled with the processor, wherein the processor determines the velocity based at least in part on information received from the GPS receiver.

3. The handheld device of claim 1, wherein under control of the processor the handheld device reorients the information based at least in part on a comparison of the determined velocity with a predetermined velocity threshold.

4. The handheld device of claim 1, wherein the reorientation comprises a change from a landscape orientation to a portrait orientation.

5. The handheld device of claim 4, wherein in the portrait orientation the bottom of the information is aligned with a side of the handheld device preselected by a user of the handheld device.

6. The handheld device of claim 1, wherein the reorientation comprises a change from a portrait orientation to a landscape orientation.

7. The handheld device of claim 6, wherein the portrait orientation and the landscape orientation are at a ninety degree offset.

8. The handheld device of claim 1, wherein under control of the processor the handheld device continually determines velocity and whether the information requires reorientation.

9. The handheld device of claim 1, wherein under control of the processor the handheld device reorients the information from a landscape orientation to a portrait orientation based at least in part on a determination that a first determined velocity is above a predetermined velocity threshold and reorients information from the portrait orientation to the landscape orientation based at least in part on a determination that a second determined velocity is below the predetermined velocity threshold.

10. The handheld device of claim 1, wherein under control of the processor the handheld device reorients the information from a landscape orientation to a portrait orientation based at least in part on a determination that a first determined velocity is above a first predetermined velocity threshold and reorients information from the portrait orientation to the landscape orientation based at least in part on a determination that a second determined velocity is below a second predetermined velocity threshold, wherein the first threshold is higher than the second threshold.

11. The handheld device of claim 1, wherein under control of the processor the handheld device reorients the information from a landscape orientation to a portrait orientation based at least in part on a determination that a determined velocity is above a predetermined velocity threshold and sets a hysteresis timer that inhibits reorientation of information from the portrait orientation to the landscape orientation for a predetermined time.

12. A handheld device, comprising:

a user interface; and

a processor communicatively coupled with the user interface, wherein under control of the processor the handheld device changes a display format for information rendered on a display of the user interface based at least in part on a determined velocity of the handheld device.

13. The handheld device of claim 12, further comprising a GPS receiver communicatively coupled with the processor, wherein the processor determines the velocity based at least in part on information received from the GPS receiver.

14. The handheld device of claim 12, wherein under control of the processor the handheld device changes the display format based at least in part on a comparison of the determined velocity with a predetermined velocity threshold.

15. The handheld device of claim 12, wherein the change comprises a change from a landscape format to a portrait format.

16. The handheld device of claim 12, wherein the change comprises a change from a portrait format to a landscape format.

17. The handheld device of claim 12, wherein under control of the processor the handheld device continually determines velocity and whether the display format requires changing.

18. The handheld device of claim 12, wherein under control of the processor the handheld device changes the display format from a landscape orientation to a portrait orientation based at least in part on a determination that a first determined velocity is above a predetermined velocity threshold and changes the display format from the portrait orientation to the landscape orientation based at least in port on a determination that a second determined velocity is below a predetermined velocity threshold.

19. A method for changing a display format for rendering information on a handheld device, comprising the steps of:

determining a velocity of the handheld device; and

changing a display format for information rendered on a display of the handheld device based at least in part on the determined velocity.

20. The method of claim 19, wherein the display format is changed from a landscape format to a portrait format.
