Patent ID: 8792944

Claim:
A method, comprising: identifying a first position and a second position of a wireless device based on a sensor reading of at least one sensor of the wireless device; storing first position data corresponding to the first position and second position data corresponding to the second position in a memory; receiving a specific pattern of touch input data on a touch pad of the wireless device, the specific pattern of touch input data identified as a predefined object which corresponds to a human ear and the touch pad being pressed against one another; comparing a difference between the first position data and the second position data to a predefined human arm movement vector stored in the memory; determining that the difference between the first position data and the second position data corresponds to a predefined human arm movement vector associated with answering an incoming call to the wireless device based on the comparing operation; identifying the specific pattern of touch input data as being similar to a predefined human ear touch pattern by comparing dimensions of the specific pattern of touch input data to a predefined human ear touch pattern stored in the memory; and changing a current operating state of the wireless device to a different operating state, which comprises changing an idle operating state to a voice receptive call answering operating state.
