Abstract: A method for detecting locations of objects in a plane, including emit light beams, one at a time, at locations along a first edge of a detection area, refract each light beam into multiple divergent light beams, direct each of the divergent beams to arrive at a respective pair of focusing lenses mounted along a second edge of the detection area, opposite the first edge, wherein an intensity profile of each divergent beam has maximum intensity along the center of the beam, for each of the focusing lenses, measure an intensity profile of that portion of the divergent beam that enters the focusing lens, for each pair of focusing lenses receiving a single divergent beam, compare the measured intensity profiles for light arriving at each lens, and determine a location of an object that partially blocks at least one of the divergent beams, based on the compares.

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: A method for identifying a proximal object, including providing light emitters, light detectors and lenses, mounted in a housing, each lens, denoted L, being positioned in relation to a respective one of the detectors, denoted D, such that light entering lens L is maximally detected at detector D when the light enters lens L at an angle of incidence θ, activating the detectors synchronously with activation of each emitter to measure reflections of the light beams emitted by each emitter, and calculating a location of a reflective object along a path of a light beam projected by an activated emitter, by calculating an axis of symmetry with respect to which the outputs of the synchronously activated detectors are approximately symmetric, orienting the calculated axis of symmetry by the angle θ, and locating a point of intersection of the path of the emitted light beam with the oriented axis of symmetry.

Abstract: Generating interactive in-air images, by emitters emitting light pulses along an in-air detection plane, light detectors, lenses configured such that there is a particular angle of entry at which each detector receives maximal light intensity when pulses enter a lens corresponding to the detector at the particular angle of entry, and there are target positions in the detection plane, associated with emitter-detector pairs, whereby for each emitter-detector pair, when an object is located at the target position, then pulses emitted by the emitter are reflected by the object into the lens corresponding to the detector at the particular angle of entry, a projector projecting an image that appears, to a user suspended in the detection plane, and a processor identifying locations of the object in the detection plane and mapping the identified locations to corresponding locations in the image, to register user interactions with the image.
