Abstract

A method and device for receiving input are provided. The method involves determining an orientation of a touchscreen. When the orientation of the touchscreen is portrait, the method involves rendering at least one input element organized according to a first set of placement rules. When the orientation of the touchscreen is landscape, the method involves rendering the at least one input element organized according to a second set of placement rules. The second set of placement rules causes each of the at least one input element to be rendered proximate to one of first and second opposite edges of the touchscreen. The device includes a processor and a touchscreen configured to carry out the method.

Claims

1. A portable electronic device comprising:

a touchscreen;

a processor configured to;

display a keyboard having a plurality of keys when touchscreen is in a portrait orientation;

in response to a change to a landscape orientation of the touchscreen, display the plurality of keys in a layout having two areas shaped as sectors of a circle, the two areas having center points at opposite edges of the touchscreen.

2. The portable electronic device of claim 1, wherein the processor is configured to display control elements on the touchscreen and proximate the edges, and the processor is configured to display the keyboard adjacent the controls elements.

3. The portable electronic device of claim 1, further comprising an accelerometer configured to detect the change in orientation.

4. The portable electronic device of claim 1, wherein the processor is configured to monitor the orientation of the touchscreen.

5. The portable electronic device of claim 4, wherein the processor is configured to monitor continuously.

6. The portable electronic device of claim 4, wherein the processor is configured to monitor periodically.

7. The portable electronic device of claim 1, wherein the processor is further configured to dynamically alter the layout of keys by moving a key closer to one of the edges of the touchscreen to within a thumb span when detecting that the key is consistently missed and thus beyond the thumb span.

8. The portable electronic device of claim 1, wherein the sectors of the circle each have a radius approximately equal to the length of a user'"'"'s thumb.

9. The portable electronic device of claim 8, wherein the processor is further configured to render each key at a location within about 10 centimeters of the respective center point.

10. The portable electronic device of claim 1, wherein the center points are located near corners of the portable electronic device.

11. A method at a portable electronic device having a touchscreen, the method comprising:

when the touchscreen is in a portrait orientation, displaying a keyboard having a plurality of keys; and

in response to a change to a landscape orientation of the touchscreen, displaying the plurality of keys in a layout having two areas shaped as sectors of a circle, the two areas having center points at opposite edges of the touchscreen.

12. The method of claim 11, further comprising displaying control elements on the touchscreen and proximate the edges, the keyboard being displayed adjacent the control elements.

13. The method of claim 11, wherein the change in orientation is detected with an accelerometer.

14. The method of claim 11, further comprising monitoring the orientation of the touchscreen.

15. The method of claim 14, wherein the orientation is monitored continuously.

16. The method of claim 14, wherein the orientation is monitored periodically.

17. The method of claim 11, further comprising dynamically altering the layout of keys by moving a key closer to one of the edges of the touchscreen to within a thumb span when detecting that the key is consistently missed and thus beyond the thumb span.

18. The method of claim 11, wherein the sectors of the circle each have a radius approximately equal to the length of a user'"'"'s thumb.

19. The method of claim 18, further comprising rendering each key at a location within about 10 centimeters of the respective center point.

20. The method of claim 11, wherein the center points are located near corners of the portable electronic device.

21. A non-transitory computer readable medium encoded with codes, the codes for directing a processor to:

display a keyboard having a plurality of keys on a touchscreen when the touchscreen is in a portrait orientation; and

in response to a change to a landscape orientation of the touchscreen, display the plurality of keys in a layout having two areas shaped as sectors of a circle, the two areas having center points at opposite edges of the touchscreen.
