Abstract
The enhanced detection of a circular engagement gesture, in which a shape is defined within motion data, and the motion data is sampled at points that are aligned with the defined shape. It is determined whether a moving object is performing a gesture correlating to the defined shape based on a pattern exhibited by the sampled motion data. An application is controlled if determining that the moving object is performing the gesture.
Claims22
A non-transitory computer-readable medium encoded with a computer program comprising instructions that, when executed, operate to cause a computer to perform operations comprising:
- defining a shape within motion data, the motion data comprising a motion history map that includes motion history data values providing, for each point of an image, an indication of time since a moving object was detected at the point;
- determining, for each point, whether the moving object has been detected within a predetermined period of time, and grouping adjacent points determined to have detected motion of the moving object within the predetermined period of time;
- sampling the motion data at one or more of the grouped points that are aligned with the defined shape;
- determining whether a moving object is performing a gesture correlating to the defined shape based on a pattern exhibited by the sampled motion data;
- and
- controlling an application if determining that the moving object is performing the gesture.
A computer-implemented method comprising:
- defining a shape within motion data, the motion data comprising a motion history map that includes motion history data values providing, for each point of an image, an indication of time since a moving object was detected at the point;
- determining, for each point, whether the moving object has been detected within a predetermined period of time, and grouping adjacent points determined to have detected motion of the moving object within the predetermined period of time;
- sampling the motion data at one or more of the grouped points that are aligned with the defined shape;
- determining whether a moving object is performing a gesture correlating to the defined shape based on a pattern exhibited by the sampled motion data;
- and
- controlling an application if determining that the moving object is performing the gesture.
A device comprising a processor configured to:
- define a shape within motion data, the motion data comprising a motion history map that includes motion history data values providing, for each point of an image, an indication of time since a moving object was detected at the point;
- determine, for each point, whether the moving object has been detected within a predetermined period of time, and grouping adjacent points determined to have detected motion of the moving object within the predetermined period of time;
- sample the motion data at one or more of the grouped points that are aligned with the defined shape;
- determine whether a moving object is performing a gesture correlating to the defined shape based on a pattern exhibited by the sampled motion data;
- and
- control an application if determining that the moving object is performing the gesture.
