One embodiment of the invention includes a gesture recognition interface system. The system may comprise a substantially vertical surface configured to define a gesture recognition environment based on physical space in a foreground of the substantially vertical surface. The system may also comprise at least one light source positioned to provide illumination of the gesture recognition environment. The system also comprises at least two cameras configured to generate a plurality of image sets based on the illumination being reflected from an input object in the gesture recognition environment. The system further comprises a controller configured to determine a given input gesture based on changes in relative locations of the input object in each of the plurality of image sets. The controller may further be configured to initiate a device input associated with the given input gesture.
