Abstract

Various devices may benefit from determinations of how users are using the devices. For example, hand-held or hand-operated devices may benefit from handedness detection and from modifications based on or related to such detection. A method can include determining a used hand of a user of a device. The method can also include modifying a graphical user interface of the device based on the determined used hand, wherein determination of the used hand occurs prior to any querying of the user regarding the used hand of the user.

Claims

1. A method, comprising:

determining a used hand of a user of a device; and

modifying a graphical user interface of the device based on the determined used hand, wherein determination of the used hand occurs prior to any querying of the user regarding the used hand of the user.

2. The method of claim 1, further comprising:

identifying a tilt of the device, wherein an identified tilt of the device is used in determination of the used hand.

3. The method of claim 2, wherein when the tilt of the device is about seventy degrees from a horizontal level, the determining comprises determining the used hand to be a right hand.

4. The method of claim 2, wherein when the tilt of the device is about one hundred ten degrees from a horizontal level, the determining comprises determining the used hand to be a left hand.

5. The method of claim 1, further comprising:

detecting a shaking event, wherein the shaking event is used in determination of the used hand.

6. The method of claim 5, wherein when the shaking event is detected, the determining comprises determining the used hand to be neutral.

7. The method of claim 5, further comprising:

when the shaking event is detected, resetting the used hand to be neutral.

8. The method of claim 1, further comprising:

requesting user confirmation of the determined used hand upon determination of the determined used hand.

9. The method of claim 8, further comprising:

locking the determined used hand upon receiving user confirmation as requested.

10. The method of claim 1, wherein the determining is performed periodically, and wherein the modifying is performed when the determining has a predetermined confidence.

11. An apparatus, comprising:

at least one processor, and

at least one memory including computer program code,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to

determine a used hand of a user of a device; and

modify a graphical user interface of the device based on the determined used hand, wherein determination of the used hand occurs prior to any querying of the user regarding the used hand of the user.

12. The apparatus of claim 11, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to identify a tilt of the device, wherein an identified tilt of the device is used in determination of the used hand.

13. The apparatus of claim 12, wherein when the tilt of the device is about seventy degrees from a horizontal level, the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to determine the used hand to be a right hand.

14. The apparatus of claim 12, wherein when the tilt of the device is about one hundred ten degrees from a horizontal level, the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to determine the used hand to be a left hand.

15. The apparatus of claim 11, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to detect a shaking event, wherein the shaking event is used in determination of the used hand.

16. The apparatus of claim 15, wherein when the shaking event is detected, the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to reset the used hand to be neutral.

17. The apparatus of claim 11, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to request user confirmation of the determined used hand upon determination of the determined used hand.

18. The apparatus of claim 17, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to lock the determined used hand upon receiving user confirmation as requested.

19. The apparatus of claim 11, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform the determination periodically, and to perform modification of the graphical user interface when the determination has a predetermined minimum confidence.

20. A method, comprising:

identifying the initiation of a contact to a touch interface;

setting an area of a display as selected point based on the contact;

identifying a motion of the contact in a first device;

moving a virtual wheel in response to the motion; and

automatically selecting an item at the selected point when the virtual wheel stops.
