Abstract: An optical sensing device includes a light source, which emits one or more beams of light pulses toward a scene. An array of single-photon detectors output electrical pulses in response to photons that are incident thereon. Light collection optics form an image of the scene on the array. Processing circuitry counts the electrical pulses output by the single-photon detectors during multiple time intervals following each of the light pulses, detects, responsively to the counted pulses, an object located less than 10 cm away from the array, makes a comparison between respective counts of the electrical pulses output by the single-photon detectors group during a specified time interval immediately following each of a plurality of the light pulses, and ascertains, responsively to the comparison, whether the object reflecting the at least one of the beams is fixed to the device or separate from the device.

Abstract: In some examples, an electronic device may be in communication with one or more input devices, including a camera, and a remote sensing vibrometer. In some examples, the remote sensing vibrometer may be configurable to emit, using a light source, one or more light beams that are incident on the physical surface on which the virtual image is displayed. In some examples, the remote sensing vibrometer detects contact with the physical surface based on one or more vibrations in the physical surface that are detected using the one or more light beams. In some examples, when the physical object contacts the physical surface on which the virtual image is displayed, the electronic device determines a location of the contact relative to the virtual image on the physical surface based on the detected vibrations produced by the contact of the physical object on the physical surface in the computer-generated environment.
