Abstract

An electronic device and a method of dynamically adapting a sensitivity of at least one user interface component on the electronic device. A device context corresponding to the electronic device can be identified and processed in real time to identify a potential user intent and to determine a probability that the potential user intent corresponds to an actual user intent. A user input sensitivity parameter can be selected based on the potential user intent and the determined probability. The sensitivity of the at least one user interface component can be adapted to correspond to the user input sensitivity parameter.

Claims

1. A method of dynamically adapting a sensitivity of at least one user interface component on an electronic device, comprising:

identifying a device context corresponding to the electronic device;

processing the device context in real time to identify a potential user intent and to determine a probability that the potential user intent corresponds to an actual user intent;

selecting a user input sensitivity parameter based on the potential user intent and the determined probability; and

adapting the sensitivity of the at least one user interface component to correspond to the user input sensitivity parameter.

2. The method of claim 1, further comprising:

when the probability that the potential user intent corresponds to the actual user intent is below or above a threshold, soliciting at least one user input prior to adapting the sensitivity of the at least one user interface component.

3. The method of claim 1, further comprising:

responsive to adapting the sensitivity of the at least one user interface component, soliciting at least one user input.

4. The method of claim 1, wherein identifying the device context corresponding to the electronic device comprises:

processing data selected from a group consisting of sensor data received from at least one sensor, data that indicates a state of at least one application instantiated on the electronic device and data corresponding to at least one user preference.

5. The method of claim 1, further comprising:

processing the device context in real time to recognize at least one user gesture;

wherein identifying the potential user intent comprises processing the user gesture.

6. The method of claim 5, wherein processing the device context in real time to recognize the at least one user gesture comprises:

identifying probability data within a map that represents a mapping between the device context and a set of probabilities that the gesture is occurring; and

associating the identified probability data with the recognized gesture.

7. The method of claim 1, wherein processing the device context in real time to identify the potential user intent and determine the probability that the potential user intent corresponds to the actual user intent comprises:

identifying probability data within a map that represents a mapping between the device context and a set of probabilities that reflect a user'"'"'s near-term intentions for using the electronic device to accomplish a specific task; and

associating the identified probability data with the potential user input.

8. The method of claim 1, wherein adapting the sensitivity of the at least one user interface component to correspond to the user input sensitivity parameter comprises:

applying a weighting factor to a control sensitivity that is determined, at least in part, on the determined probability in order to determine a user input sensitivity parameter that is applied to the user interface component.

9. The method of claim 1, further comprising:

selecting a haptic response parameter based on the potential user intent and the determined probability; and

communicating the haptic response parameter to the user interface to indicate to the user interface to generate a haptic response via the at least one user interface component.

10. An electronic device, comprising:

a controller that;

identifies a device context corresponding to the electronic device;

processes the device context in real time to identify a potential user intent and to determine a probability that the potential user intent corresponds to an actual user intent;
