1. An apparatus comprising:
a light guide panel including a plurality of diffraction gratings to cause light to propagate within the light guide panel by total internal reflection and scatter light in response to a presence of an object adjacent to the light guide panel; a light emitter adjacent to the light guide panel to transmit light to the plurality of diffraction gratings; and a light detector adjacent to the light guide panel to detect light propagated by the light guide panel. |
