摘要： Various embodiments related to determining a distance of an object from a surface of an interactive display device are disclosed herein. For example, one disclosed embodiment provides a method comprising, directing infrared (IR) light to the object above the surface which is reflected by the object back to the interactive display device, and refracting IR light reflected from the object into two rays travelling in different directions based on a polarization state of the reflected IR light. The method further comprises switching a polarization state of an LCD device to allow one of the two refracted rays to pass through the LCD device, and receiving, at a detector, the one of the two refracted ray that passes through the LCD device. Further, the method comprises estimating a distance of the object from the surface based on triangulation.

摘要： A light guide of the tapered-waveguide type includes an input slab (30) for expanding a projected image between an input end and an output end (40); and a tapered output slab (10) arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide (30) is greater in the transverse direction away from the centre line C, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide (10) bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.
