Movement detection system for a portable device such as a portable phone

摘要

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.

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; a microphone, in said housing, that operates to sense said changes, said microphone sensing changes to an environmental condition surrounding said housing, wherein said environmental conditions comprises a profile of noises sensed by the microphone.
