Abstract: A sensor, including light emitters projecting directed light beams, light detectors interleaved with the light emitters, lenses, each lens oriented relative to a respective one of the light detectors such that the light detector receives maximum intensity when light enters the lens at an angle b, whereby, for each emitter E, there exist corresponding target positions p(E, D) along the path of the light from emitter E, at which an object located at any of the target positions reflects the light projected by emitter E towards a respective one of detectors D at angle b, and a processor storing a reflection value R(E, D) for each co-activated emitter-detector pair (E, D), based on an amount of light reflected by an object located at p(E, D) and detected by detector D, and calculating a location of an object based on the reflection values and target positions.

Abstract: Method including providing a sensor including light emitters, photodiode detectors, and lenses arranged so as to direct light beams from light emitters exiting lenses along a detection plane, and so as to direct light beams entering lenses at a specific angle of incidence onto photodiode detectors, mounting the sensor on a display presenting virtual input controls for an electronic device, such that the detection plane resides in an airspace in front of the display, activating light emitters to project light beams through lenses along the detection plane, wherein at least one of the light beams is interrupted by a finger, detecting light reflected by the finger, identifying emitters that projected the light beam that was reflected and photodiode detectors that detected the reflected light, as emitter-detector pairs, calculating display coordinates based on target positions associated with the identified emitter-detector pairs, and transmitting the calculated display coordinates to the electronic device.
