Patent ID: 8902181

Claim:
A method, performed by a tablet computing device, for detecting gestures, comprising: receiving touch input information from at least one touch input mechanism, in response to a user touching the computing device; receiving movement input information from at least one movement input mechanism, in response to movement of the computing device; determining whether the touch input information and the movement input information indicate that the user has performed or is performing a multi-touch-movement gesture, where the multi-touch-movement gesture entails: establishing two or more contacts with a surface of the computing device by a user who grasps the computing device with two hands during use; and moving the computing device to establish a prescribed posture; after determining that the user has performed a multi-touch-movement gesture, evaluating data from one or more sensors of the tablet computing device to determine whether a predefined telltale noise signature representing a predefined pattern of behavior has occurred; and cancelling implementation of the multi-touch-movement gesture when the predefined telltale noise signature has occurred.
