摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sensing touch and/or gestures in the near-field area overlying a light-guiding layer within a device or other optical sensing system. In one aspect, modulated infrared light is emitted into the overlying area, and the light reflected by objects within the overlying area is redirected through the light-guiding layer to infrared sensors. In one aspect, a masking structure can be located between the light-guiding layer and the infrared sensors. In some aspects, probability mapping or backtracing can be used to estimate the locations of objects within the overlying area.

摘要： Light modulator displays may be illuminated using a light guide comprising diffractive optics that directs light onto an array of light modulators. A holographic light turning element may be included with the light guide to turn light propagating within the light guide onto the light modulators. In some embodiments, the holographic element is configured to distribute a substantially uniform amount of light across the array of modulators. The holographic element may, for example, have a turning efficiency that changes along the length of the holographic element. A holographic element can also be used to function as a light bar. Such a holographic element may receive light from a light source such as a light emitting diode and distribute the light along a light guide disposed in front of an array of light modulators.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for providing a gesture-responsive user interface for an electronic device. In one aspect, an apparatus or electronic device has an interactive display that provides an input/output (I/O) interface to a user of the apparatus. The apparatus includes a processor, a light emitting source and at least two light sensors. A secondary optical lens structures emitted light from the light emitting source into at least one lobe. Each light sensor outputs, to the processor, a signal representative of a characteristic of received light, where the received light results from scattering of the structured emitted light by an object. The processor effectuates the I/O interface by recognizing, from the output of the light sensors, an instance of a user gesture, and to control the interactive display and/or the apparatus in response to the user gesture.

摘要： An illumination apparatus includes a light bar having a first end for receiving light from a light source. The light bar includes material that supports propagation of the light along the length of the light bar. Turning microstructure is disposed on a first side of the light bar. The turning microstructure is configured to turn a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light bar. A light guide panel is disposed with respect to a second opposite side of the light bar to receive the light turned by said turning microstructure and directed out of the second opposite side of the light bar. An optical coupler has an input surface and an output surface. The input surface is disposed to receive the light directed out of the second opposite side of the light bar. The output surface is disposed to couple light from the optical coupler into the light guide panel. The output surface of the optical coupler is tapered.

摘要： This disclosure relates to an interactive display, having a front surface including a viewing area, and providing an input/output interface for a user of an electronic device. A planar light guide (PLG) disposed substantially parallel to the front surface, has a periphery at least coextensive with the viewing area. A light-emitting source (LES), disposed outside the periphery of the PLG, is optically coupled with a PLG input. The PLG outputs reflected light, in a direction substantially orthogonal to the front surface, by reflecting light received from the LES. A light collecting device (LCD) collects scattered light that results from interaction of the reflected light with a user-controlled object. The LCD redirects the collected scattered light toward one or more light sensors. A processor recognizes, from outputs of the light sensors, an instance of a user gesture, and controls the interactive display and/or electronic device, responsive to the user gesture.
