Predictive information for free space gesture control and communication

A non-transitory computer readable medium, storing instructions for distinguishing between alternative motions between two observed locations of a control object in a three-dimensional (3D) sensory space, which instructions, when executed by one or more processors perform actions including:

• accessing a first position and a second position of a segment of a control object;
• receiving two or more alternative interpretations of movement from the first position to the second position;
• receiving a selection of an alternative interpretation of the two or more alternative interpretations;
• and
• using the alternative interpretation selected to interpret a control object's position and/or motion.

A system enabling updating a predictive model comprising:

• a gesture database comprising a electronically stored information, the electronically stored information relating to a predictive model of a hand;
• and
• an image analyzer coupled to the gesture database and having one or more hardware processors configured with logic to:
• access a particular predictive model of the hand;
• obtain using points in a set of points defined for the hand and the predictive model, a refined predictive model having refined positions of segments determined for the set of points;
• and
• using the predictive model as refined to interpret a control object's position and/or motion.

A computer implemented method to distinguish between alternative motions between two observed locations of a control object in a three-dimensional (3D) sensory space, the method including:

• accessing a first position and a second position of a segment of a control object;
• receiving two or more alternative interpretations of movement from the first position to the second position;
• receiving a selection of an alternative interpretation of the two or more alternative interpretations;
• and
• using the alternative interpretation selected to interpret a control object's position and/or motion.
