    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 method of enhancing input imaging resolution includes sequentially blocking light from different portions of an object with a series of resolution-enhancing patterns displayed between the object and an image detector. The method further includes detecting light filtered by the series of resolution-enhancing patterns and integrating light detected while different resolution-enhancing patterns of the series of resolution-enhancing patterns are displayed between the object and the detector.

    摘要: Embodiments are disclosed herein that relate to the front-projection of an interactive display. One disclosed embodiment provides an interactive display system comprising a projector and a display screen configured to display an image projected by the projector, the display screen comprising a retroreflective layer and a diffuser layer covering the retroreflective layer, the diffuser layer being configured to diffusely reflect only a portion of light incident on the diffuser layer from the projector such that another portion of light passes through the diffuser layer and is reflected by the retroreflective layer back through the diffuser layer. The interactive display system also comprises a camera configured to capture images of the display screen via light reflected by the retroreflective layer to identify via the images a user gesture performed between the projector and the display screen.

    摘要: A light guide of the tapered-waveguide type includes an input slab for expanding a projected image between an input end and an output end, and an output slab arranged to receive rays from the said output end, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The input slab and output waveguide are matched so that all rays injected into the input end undergo the same number of reflections before leaving the output surface. With the invention, the input slab is itself tapered slightly towards the output waveguide. This means that input and output waveguides can be made the same length, in the direction of ray travel, and can therefore be folded over each other with no wasted space.
