    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 of optical collimators are disclosed. For example, one disclosed embodiment comprises an optical waveguide having a first end, a second end opposing the first end, a viewing surface extending at least partially between the first end and the second end, and a back surface opposing the viewing surface. The viewing surface comprises a first critical angle of internal reflection, and the back surface is configured to be reflective at the first critical angle of internal reflection. Further, an end reflector is disposed at the second end of the optical waveguide, and includes a faceted lens structure to cause a majority of the viewing surface to be uniformly illuminated when uniform light is injected into the first end and also to cause a majority of the injected light to exit the viewing surface.

    摘要： Embodiments are disclosed that relate to private video presentation. For example, one disclosed embodiment provides a system including a display surface, a directional backlight system configured to emit a beam of light from the display surface and to vary a direction in which the beam of light is directed, and a spatial light modulator configured to form an image for display via the directional backlight system. The system further includes a controller configured to control the optical system and the light modulator to display a first video content item at a first viewing angle and a second video content item at a second viewing angle.
