摘要： This disclosure provides systems, methods and apparatus for a touch screens configured to determine a position of a touch event by selectively redirecting light to correlated locations on a light sensor. In one aspect, the touch screen apparatus can include a light guide forming a touch interface, a light source for injecting light into the light guide, a light sensor for detecting the injected light, and a pixilated light-turning layer. The pixilated light-turning layer can include a plurality of light-turning features forming pixels. The pixels can receive incident light corresponding to the emitted light scattered by an object contacting the light guide. The pixels can redirect the incident scattered light towards the light sensor such that light selectively propagates to one or more correlated light receiving locations. A processor can map the light receiving location to an area contacted by the object, thereby determining a position of a touch event.

摘要： The present disclosure provides systems, methods and apparatus to produce a plurality of virtual light sources and at least partially collimate light. In one aspect, a manifold to collimate light can produce a plurality of virtual light sources used to inject light into a light guide for illuminating a display. The manifold can be formed of optically transmissive material and can have a backside for receiving light from a light source and a front wall, opposite the backside, for outputting light. The front wall can include first and second output portions separated by a non-light emitting area, each of the output portions providing a separate virtual light source. The upper, bottom, and side walls of the manifold can extend along a curve from the backside to the front wall and can be configured to collimate light propagating in directions extending out of the plane of the light guide.

摘要： This disclosure provides systems, methods and apparatus for an imaging system that includes a light guide having light-turning features that are configured to receive ambient light incident on the light guide, including light scattered from a scene to be imaged, and to direct the received ambient light towards an image sensor. The light-turning features may have angle-discriminating properties so that some light-turning features capture light incident upon the light guide at certain angles of incidence, but not others. Light scattered from multiple parts of a scene to be imaged may then be directed to correlated locations on an image sensor, which provides electronic data representing an image.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for two dimensional position determination of an object. In one aspect, a first electromagnetic (EM) radiation and a second EM radiation is emitted, along a plane, toward a position-sensing region, the first and second EM radiation each having a respective, different, wavelength. Scattered radiation, resulting from interaction of the emitted first and second EM radiation with an object located in the position-sensing region, is detected. Characteristics of the detected scattered radiation have a correlation with a position of the object in the position-sensing region. A two dimensional position of the object is determined, from the correlation. The position-sensing region may be co-planar with, and/or disposed proximate and parallel to an external surface of a display screen.

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.
