Gesture cataloging and recognition

摘要

A total variance may be computed for sample values in an input gesture including a plurality of sample values of sample motion data from one or more sensors associated with a control device. The motion data may be related to movement of a control device. A figure of merit may be calculated using the sample values in the gesture, the total variance for the sample values in the input gesture, and sample values in one or more catalog gestures. The figure of merit measures how well the samples in the input gesture match samples in the catalog gesture. Whether an input gesture matches one of the one or more catalog gesture may be determined based on the figure of merit. A state of the system may be changed if it is determined that the input gesture matches the one of the one or more catalog gestures.

1. In a system having a control device and a processor coupled to the control device, a gesture recognition method comprising:
a) computing with the processor a total variance for sample values in an input gesture including a plurality of sample values of sample motion data from one or more sensors associated with the control device wherein the motion data is related to movement of the control device; b) calculating a figure of merit using the sample values in the gesture, the total variance for the sample values in the input gesture, and sample values in one or more catalog gestures, wherein the figure of merit measures how well the samples in the input gesture match samples in the catalog gestures; c) determining whether an input gesture matches one of the one or more catalog gesture based on the figure of merit; and d) changing a state of the system if it is determined that the input gesture matches the one of the one or more catalog gestures.
