Abstract: An apparatus includes a display stack comprising at least one layer to generate a digital display image. A front stack includes a position encoded contrast layer to provide a pattern of light in response to non-visible light applied to the position encoded contrast layer. The pattern of light encodes spatial information across a surface of the position encoded contrast layer. A hot mirror reflects the non-visible light applied to the position encoded contrast layer of the front stack and is optically transparent to visible light generated from the display stack.

Abstract: An apparatus includes a light source to transmit non-visible light pulses strobed at a frequency and a duty cycle. A detector a detector receives a pattern of reflected light from a display in response to the non-visible light pulses. The pattern of reflected light had at least two different polarization states, where the detector determines a spatial location of the detector relative to the display based on discriminating between the at least two polarization states.
