Abstract
A computing device for identifying a gesture performed by a tracked object in an image stream, said computing device comprising a memory and a controller, wherein said controller is configured to: determine a movement vector for the tracked object, compare the movement vector against a reference library of gestures, and thereby identify a gesture matching the movement vector, wherein said movement vector comprises at least one partial movement having a direction being identified by a relative angle and wherein said comparison is based on said relative angle.

20. A computing device for identifying a gesture performed by a tracked object in an image stream, said computing device comprising a memory and a controller, wherein said controller is configured to:
-
determine a movement vector for the tracked object; compare the movement vector against a reference library of gestures; and
thereby identify a gesture matching the movement vector,wherein said movement vector comprises at least one partial movement having a direction being identified by an angle and wherein said comparison is based on said angle, wherein said controller is further configured to correct for a misalignment of said computing device by determining said angle as a relative angle between a direction of a first partial movement and a direction of a second partial movement. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method for use in a computing device for identifying a gesture performed by a tracked object in an image stream, said method comprising:
-
determining a movement vector for the tracked object; comparing the movement vector against a reference library of gestures; and
thereby identifying a gesture matching the movement vector,wherein said movement vector comprises at least one partial movement having a direction being identified by an angle and wherein said comparison is based on said angle, wherein said method further comprises correcting for a misalignment of said computing device by determining said angle as a relative angle between a direction of a first partial movement and a direction of a second partial movement. - View Dependent Claims (38)
