A proximity sensor including a structure suspending at least one lens above a circuit board, light emitters operable to project light beams through the lens along a common projection plane, light detectors operable to detect amounts of light arriving through the lens at the detector, wherein an object in the projection plane reflects light from an emitter to one or more of the detectors, and wherein each emitter-detector pair, including one of the emitters and one of the detectors, when synchronously activated, is expected to generate a greater detection signal at the activated detector than the other detectors, were they to be synchronously activated with any of the emitters, when the object is located at a specific 2D location in the projection plane corresponding to the emitter-detector pair, and a processor identifying gestures performed by the object based on amounts of light detected by the detector of each emitter-detector pair.

Contactless touch input system

A method for interacting with controls in a graphical user interface (GUI), including recording user interface gestures performed by a user, for each recorded gesture: when the gesture includes the user virtually touching a specific GUI control, applying the gesture to the specific GUI control; and when the gesture is performed without the user virtually touching a specific GUI control, identifying a particular GUI control that the user is gazing at and applying the gesture to that particular GUI control.

User interface

A proximity sensor, including light emitters and light detectors mounted on a circuit board, two stacked lenses, positioned above the emitters and the detectors, including an extruded cylindrical lens and a Fresnel lens array, wherein each emitter projects light through the two lenses along a common projection plane, wherein a reflective object located in the projection plane reflects light from one or more emitters to one or more detectors, and wherein each emitter-detector pair, when synchronously activated, generates a greatest detection signal at the activated detector when the reflective object is located at a specific 2D location in the projection plane corresponding to the emitter-detector pair, and a processor sequentially activating the emitters and synchronously co-activating one or more detectors, and identifying a location of the object in the projection plane, based on amounts of light detected by the detector of each synchronously activated emitter-detector pair.

A method for interacting with controls in a graphical user interface (GUI) having a plurality of GUI controls, the method includes identify one GUI control that a user is gazing at, from among a plurality of GUI controls presented on a display, detect user interface gestures performed by the user, when the detected gesture is performed in an airspace away from the display, apply a relative motion corresponding to the gesture to the identified GUI control, and when the detected gesture is performed by the user touching the display, apply a sequence of absolute display locations touched by the gesture to a GUI control presented at the touched locations that is different than the identified GUI control.

An input panel for an electronic device, including an arrangement of buttons, wherein each button is actuated when pressed, providing input to an electronic device, and a sensor, detecting location of a user's finger above the buttons, the sensor including a housing, a printed circuit board, light emitters and photodiode detectors, lenses mounted in the housing in such a manner that, when the housing is mounted along an edge of the arrangement, the lenses direct light from the emitters along a plane above the buttons, and direct light from the plane, reflected toward the lenses by an object inserted into the plane, onto the detectors, a processor configured to identify a location in the plane at which the object is inserted based on the detections of light reflected by the object, and a communications port configured to output the identified location to the electronic device.

Contactless control panel

A sensor including lenses, light emitters, each emitter projecting light out of a lens in a particular emission direction along a detection plane, light detectors, each detector detecting maximum light intensity when light enters a lens at a particular detection angle, a table of hotspots, each hotspot corresponding to an emitter-detector pair, the hotspot being a two-dimensional location in the detection plane along the emission direction of the emitter of the pair where projected light reflected by an object placed at that location, enters the lens for the detector of the pair at the detection angle of the detector, and a processor receiving outputs from the detectors corresponding to detected amounts of projected light reflected by an object in the detection plane, and calculating a two-dimensional location of the object in the detection plane based on the received outputs and based on hotspots for synchronously activated emitter-detector pairs.

Optical proximity sensor

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.

Optical proximity sensor and associated user interface

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 &#x3b8;, 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 &#x3b8;, and locating a point of intersection of the path of the emitted light beam with the oriented axis of symmetry.

A proximity sensor including a housing, light emitters mounted in the housing for projecting light out of the housing along a detection plane, light detectors mounted in the housing for detecting amounts of light entering the housing along the detection plane, whereby for each emitter-detector pair (E, D), when an object is located at a target position p(E, D) in the detection plane, corresponding to the pair (E, D), then the light emitted by emitter E is scattered by the object and is expected to be maximally detected by detector D, and a processor to synchronously activate emitter-detector pairs, to read the detected amounts of light from the detectors, and to calculate a location of the object in the detection plane from the detected amounts of light, in accordance with a detection-location relationship that relates detections from emitter-detector pairs to object locations between neighboring target positions in the detection plane.
