Abstract

Systems and methods for processing data from a motion sensor to detect intentional movements of a device are provided. An electronic device having a motion sensor may process motion sensor data along one or more dimensions to generate an acceleration value representative of the movement of the electronic device. The electronic device may then determine whether the acceleration value changes from less than a low threshold, to more than a high threshold, and again to less than the low threshold within a particular amount of time, reflecting an intentional movement of the electronic device by the user. In response to determining that the acceleration value is associated with an intentional movement of the electronic device, the electronic device may perform a particular event or operation. For example, in response to detecting that an electronic device has been shaken, the electronic device may shuffle a media playlist.
