摘要： A touch-pressure sensitive panel includes a locally and resiliently deformable waveguide having an exterior surface for receiving localized touch pressure from a user, and a wetting surface opposite the exterior surface. The panel also includes a de-wettable layer presenting a de-wettable surface arranged beneath the wetting surface, such that the localized touch pressure reversibly increases localized optical wetting of the de-wettable surface by the wetting surface. The panel also includes an imaging detector configured to receive light coupled into the de-wettable layer due to the localized optical wetting.

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.
