1. A gesture recognition interface system comprising: at least one light source positioned to illuminate a first side of a light-diffusive screen configured to display visual content; 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 performed in a foreground of the second side based on a brightness contrast difference between diffused illumination from the at least one light source via the light-diffusive screen and an input object; a projector configured to provide the visual content; a beamsplitter configured to combine light emitted from the at least one light source and the visual content substantially on-axis on the first side of the light-diffusive screen; and a controller configured to determine a given input gesture that is interactive with the visual content based on changes in relative locations of the input object in the plurality of images, and being further configured to initiate a device input associated with the given input gesture.
