  • defining a shape corresponding to a gesture within motion data;

    sampling the motion data at points that are aligned with the defined shape;

    determining, based on the sampled motion data, positions of a moving object along the defined shape, over time, wherein determining the positions occurs subsequent to defining the shape;

    determining whether the moving object is performing the gesture based on a pattern exhibited by the determined positions; and

    controlling an application if determining that the moving object is performing the gesture.
