Multi-touch-movement gestures for tablet computing devices

摘要

Functionality is described herein for detecting and responding to gestures performed by a user using a computing device, such as, but not limited to, a tablet computing device. In one implementation, the functionality operates by receiving touch input information in response to the user touching the computing device, and movement input information in response to the user moving the computing device. The functionality then determines whether the input information indicates that a user has performed or is performing a multi-touch-movement (MTM) gesture. The functionality can then perform any behavior in response to determining that the user has performed an MTM gesture, such as by modifying a view or invoking a function, etc.

1. 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; andmoving 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.
