Context-based user interface system

1. An electronic device user interface system comprising:

a user interface management module configured to determine whether a sequential context condition has been satisfied and to select a user interface content mode based on a velocity signal indicative of a context of the electronic device, wherein the velocity signal indicates a velocity at which the electronic device is moving, and wherein the sequential context condition comprises a plurality of contexts of the electronic device occurring in a specified sequence.

2. The electronic device of claim 1 , wherein the context is based on information detected by a sensor.

3. The electronic device of claim 2 , wherein the sensor is a velocity sensor.

4. The electronic device of claim 1 , wherein the user interface management module is configured to change the user interface content mode in response to a change in the context.

5. The electronic device of claim 1 , wherein the velocity signal is indicative of an “Automobile” context of the electronic device if the velocity signal is above a threshold.

6. The electronic device of claim 5 , wherein the velocity signal is indicative of a “Walking” context of the electronic device if the velocity signal is below the threshold.

7. The electronic device of claim 1 , wherein the velocity signal determines whether the electronic device is located in an automobile, is located in an airplane, or is being carried by a user on foot.

8. An electronic device user interface method, comprising:

detecting a plurality of contexts in which the electronic device is operating at a given time, each context indicative of a corresponding user interface content mode, wherein each user interface content mode has a priority; and

automatically configuring the electronic device to operate in a highest priority one of the user interface content modes.

9. The method of claim 8 , further comprising detecting the contexts based on information detected by at least one sensor.

10. The method of claim 8 , further comprising detecting at least one of the contexts based on the location of the electronic device.

11. The method of claim 8 , further comprising changing the user interface content mode in response to a change in at least one of the contexts.

12. The method of claim 8 , further comprising changing the user interface content mode based on a velocity at which the electronic device is moving.

13. The method of claim 8 , further comprising determining whether at least one defined sequential context condition has been satisfied, wherein each defined sequential context condition comprises a plurality of individual context conditions occurring in a specified sequence.

14. The method of claim 13 , wherein none of the individual context conditions is satisfied by an instruction provided to the system by a user.

15. The method of claim 8 , wherein the priority of each user interface content mode is based on its frequency of use.

16. The method of claim 8 , wherein the priority of each user interface content mode is based on the safety of a user of the electronic device.

17. An electronic device user interface system comprising:

a user interface management module having at least one sequential context condition defined by an application module, the application module configured to modify a user interface content mode in response to the sequential context condition being satisfied, wherein each sequential context condition comprises a plurality of individual context conditions occurring in a specified sequence.

18. The system of claim 17 , wherein each individual context condition is based on information detected by a sensor.

19. The system of claim 17 , wherein at least one of the individual context conditions is based on a velocity at which the electronic device is moving.

20. The system of claim 17 , wherein the at least one sequential context condition is registered with at least two different user interface content modes.

21. The system of claim 17 , wherein none of the individual context conditions is satisfied by an instruction provided to the system by a user.
