Patent ID: 8760392

Claim:
A handheld device, comprising: a sensor component configured to generate, based on a data sampling rate, data in response to detection of a movement of the handheld device using sensors comprising a 3-axis angular rate sensor and a 3-axis linear acceleration sensor; a processor component configured to: adaptively adjust the data sampling rate based on a determination that the movement satisfies a condition with respect to an amount of motion of the handheld device, wherein the data sampling rate adaptively increases as the amount of motion increases, and wherein the data sampling rate adaptively decreases as the amount of motion decreases; determines, based on the condition, different power states for different portions of the sensors associated with different axes of the handheld device; adjust the data sampling rate based on an expected movement; process portions of the data to obtain processed data; and send the processed data directed to a base station via a wireless network, the processed data being a digital word and time stamp, wherein the digital word identifies a predefined gesture or movement.
