Abstract
One embodiment of the invention includes a method of providing device inputs. The method includes illuminating hand gestures performed via a bare hand of a user in a foreground of a background surface with at least one infrared (IR) light source. The method also includes generating a first plurality of silhouette images associated with the bare hand based on an IR light contrast between the bare hand and the background surface and generating a second plurality of silhouette images associated with the bare hand based on an IR light contrast between the bare hand and the background surface. The method also includes determining a plurality of three-dimensional features of the bare hand relative to the background surface based on a parallax separation of the bare hand in the first plurality of silhouette images relative to the second plurality of silhouette images. The method also includes determining a provided input gesture based on the plurality of three-dimensional features of the bare hand and comparing the provided input gesture with a plurality of predefined gesture inputs in a gesture library. The method further includes providing at least one device input corresponding to inte…
