Abstract

An unintentional dialing event is detected by characterizing some action of a portable phone, e.g., its movement or its surroundings. The action can be characterized by a sensor, and that sensor can be for example an accelerometer, a camera in the phone, or a microphone in the phone, or some other way. The movement can be characterized to see if it is synchronous with entries on the keyboard, which would likely represent the unintentional dialing event or “but dialing”. The environment can also be characterized other ways, for example by using a microphone in the phone to text sound profiles or to detect sounds in sync with the entries, or can be characterized using a camera in the phone to detect a light profile.

Claims

1. A portable communication device, comprising:

a housing;

a processor, in the housing, and detecting information indicative of changes in an environment of the portable communication device,

said processor also detecting actuations to a user interface of the portable communication device,

said processor comparing said changes to said actuations, and detecting a synchronism between said changes and said actuations;

and if said changes are detected to be in synchronism with said actuations, executing a routine that prevents said actuations from carrying out a first function, and otherwise if said changes are not in synchronism with said actuations, carrying out said first function.

2. The device as in claim 1, wherein said first function is a function that occurs without further user confirmation and if said changes are detected to be in synchronism with said actuations, said processor requiring user confirmation.

3. The device as in claim 1, wherein said processor compares said changes to at least one profile of movements.

4. The device as in claim 1, further comprising a sensing device, in said housing, that operates to sense said changes, said sensing device sensing changes to an environmental condition surrounding said housing.

5. The device as in claim 4, wherein said sensing device is a camera.

6. The device as in claim 5, wherein said environmental condition comprises a profile of light and darkness.

7. The device as in claim 1, wherein said processor further comprises detecting a second communication that is an emergency call, and wherein said second communication is made independent of comparing the changes to the actuations.

8. The device as in claim 4, wherein said sensing device is a microphone.

9. The device as in claim 8, wherein said environmental conditions comprises a profile of noises sensed by the microphone.

10. A method of operating portable communication device, comprising:

using a processor in a housing of the portable communication device for operating a user interface to detect actuations on the user interface that carry out functions including initiating a first communication;

using the processor for detecting changes in an environment of the portable communication device;

comparing said changes to said actuations, and detecting a synchronism between said changes and said actuations;

if said changes are detected to be in synchronism with said actuations, preventing said actuations from carrying out a first function, and

if said changes are not in synchronism with said actuations, carrying out said first function.

11. The method as in claim 10, wherein said first function is a function that occurs without further user confirmation and if said changes are detected to be in synchronism with said actuations, requiring user confirmation.

12. The method as in claim 11, wherein said processor detects information from a sensor in said housing, said sensor sensing changes to an environmental condition surrounding said housing and said processor detecting information indicative of said changes in the environmental condition.

13. The method as in claim 12, wherein said sensor is a camera, and said environmental condition is a profile of light and darkness.

14. The method as in claim 11, wherein said processor further comprises detecting a second communication that is an emergency call, and wherein said second communication is made independent of comparing the changes to the actuations.

15. The method as in claim 12, wherein said sensor is a microphone, and said environmental condition is a profile of noises sensed by the microphone.

16. A portable communication device, comprising:

a housing;

a user interface, in the housing;

a processor, in the housing, and detecting information indicative of changes in an environment of the portable communication device, said processor detecting changes based on a first output from a camera in the housing, and also detecting changes based on a second output from a microphone in the housing,

said processor also detecting at least one actuation to the user interface;

said processor analyzing said changes in both said first output and in said second output, and said actuation, and detecting a relationship between said changes and said actuations;

said processor preventing said actuations from carrying out a first function when there is a first relationship between said first and second output and said actuations, and allowing said actuation to carry out said first function when there is a second relationship different than the first relationship between said first and second output and said actuation.

17. The device as in claim 16, wherein said relationships comprise temporal synchronization between multiple actuations and outputs from said camera and said microphone.

18. The device as in claim 16, wherein said processor compares said changes to said first output and said second output to at least one profile of movements.

19. The device as in claim 18, wherein said profile comprises a profile of light and darkness.

20. The device as in claim 18, wherein said profile comprises a profile of noises sensed by the microphone.
