Abstract
A method for determining a gesture illuminated by a light source utilizes the light source to provide illumination through a work volume above the light source. A camera is positioned to observe and determine the gesture performed in the work volume.
Claims30
A computer implemented method comprising:
- providing a light source adapted to direct illumination through a work volume above the light source;
- providing a camera oriented to observe a gesture performed in the work volume, the camera being fixed relative to the light source;
- and
- determining, using the camera, the gesture performed in the work volume and illuminated by the light source.

A computer apparatus comprising:
- a light source adapted to illuminate a human body part within a work volume generally above the light source;
- a camera in fixed relation relative to the light source and oriented to observe a gesture performed by the human body part in the work volume;
- and
- a processor adapted to determine the gesture performed in the work volume and illuminated by the light source based on the camera output.
