摘要 |
One embodiment of the invention includes a gesture recognition interface system. The interface system may comprise at least one light source positioned to illuminate a first side of a light-diffusive screen. The interface system may also comprise at least one camera positioned on a second side of the light-diffusive screen, the second side being opposite the first side, and configured to receive a plurality of images based on a brightness contrast difference between the light-diffusive screen and an input object. The interface system may further comprise a controller configured to determine a given input gesture based on changes in relative locations of the input object in the plurality of images. The controller may further be configured to initiate a device input associated with the given input gesture.
