Abstract

In one embodiment, a method includes providing a device that includes at least one touch sensor. The device has a plurality of surfaces and edges. A plurality of touches at one or more of the surfaces or edges are detected. At least one of these touches is detected at a surface or edge that is distinct from a front surface of the device that overlays an electronic display of the device and includes a touch-sensitive area. A user action is identified based upon at least the plurality of touches at the one or more surfaces or edges of the device.

correlating, by the device, the particular user action with a function of the device, the correlation determined using the particular mode of operation of the device and the identified user action; and

performing, by the device, the function of the device that is correlated with the particular user action.

4. The method of claim 1, wherein identifying the particular user action includes identifying a hold position that indicates the manner in which the device is being held by one or both hands of a user of the device.

5. The method of claim 4, the identifying the hold position comprising selecting the hold position from a plurality of hold positions, each hold position defined, at least in part, by a plurality of simultaneous touches at one or more surfaces of the device that are distinct from the front surface of the device.

6. The method of claim 1, the identifying the particular user action comprising associating at least one touch of the at least one touch with a particular finger of a user of the device.

7. The method of claim 1, the identifying the particular user action further comprising:

calculating a first location of the device based on a second location of a first touch of the at least one touch; and

determining whether a second touch of the at least one touch occurred at the first location of the device.

8. The method of claim 1, the particular user action comprising a scrolling or zooming motion performed on a surface of the device that adjoins the front surface, an edge of the front surface of the device, or an edge of the back surface of the device.

9. The method of claim 1, the identifying the particular user action further based on at least one sensor input from a sensor that is not a touch sensor.

10. The method of claim 9, the at least one sensor input comprising one or more of:

an acceleration measurement performed by an accelerometer of the device; and

an orientation of the device detected by a gyroscope of the device.

11. The method of claim 3, the performing the function of the device comprising unlocking the device.

12. One or more computer-readable non-transitory storage media embodying logic that is configured when executed to:

access a plurality of records that define a plurality of user actions that may be performed on a device, the device including at least one touch sensor, the device having a plurality of surfaces and a plurality of edges, each surface of the plurality of surfaces separated from at least one adjoining surface of the plurality of surfaces by a respective edge of the plurality of edges of the device, each edge of the plurality of edges comprising an angle of deviation between two surfaces of the plurality of surfaces of at least approximately 45°
