In March, Reuters reported that "most Android phones must wait until 2019 to duplicate the 3D sensing feature behind Apple's Face ID security according to three major parts of manufacturers." Part of the delay is due to the lack of surface-emitting vertical cavity, or VCSEL's supply. The supply issue aside, Google was granted a patent today by the US Patent and Trademark Office which covers future use of VCSELs in products such as a Pixel smartphone.
Google was given patent 1
Google patent covers the same type of "pattern lighting projector." Google patent 5 below is a block diagram of an example system that includes a listener and a light detector, Fig. 6 is a flow chart of a method of to operate a light emitter to produce lighting patterns.
Google notes in its patented patent that "Light emitter # 560 produces a particular lighting pattern includes generating light from a set of one or more paired light emitting elements (eg LEDs, lasers, VCSELs) of door # 570.
Light emitter # 560 can be part of a smart phone, digital assistant, headphone, controller for a robot or other system or other portable data processing device .
In such examples, the light transmitted from the light emitter (e.g., as different illumination patterns) can be used to determine the location of objects (e.g., of objects including light detectors) relative to such other objects The location of a user's hand, on which is a light sensor placed in relation to a user's head, where a head-mounted display including light emitter 560 is arranged.)  Alternatively, the light transmitter may be part of a system mounted on a floor, wall, ceiling or other object or building so that the light emitter's location is relatively static relative to an environment of interest.
Object # 500 in Fig. 5 may be part of or disposed of on a system (such as a drone), a tag or other device that is associated with an item or person who is interested (for example, to a body segment of a person to light motion recording) or otherwise configured to facilitate determining the location of object # 500 based on a time varying light intensity received from the listener.
Google further states that "It may be beneficial in a variety of applications to detect and / or determine the location of an object in an environment. These programs may include tracking a drone, a ball used in a game, a conductor baton, a controller, a body part of a person (e.g., for motion capture or motion detection ) or any object (s).
In an example of an application, the location of a plurality of markers or codes arranged at different locations on a person's body could be determined and used to detect the locality and / or movements of the person and / or particular parts of the person's body. 19659003]
In another example, the location of a control wall or other device, relative to a head mounted device or other device carried by a person, detected and used as an input to the head mounted device or other system.
In e For example, placing a drone, robot or other mobile system in an interested environment (e.g. a room in a house, a warehouse, a factory) could be determined and used to control the movement of drone, robot, or other mobile system in the environment. "
In March, CEO and General Manager of Apple Provider Finisar Allen, Curtis Barratt, pointed to motion detection as a very important application associated with VCSEL Lasers for 3D Sensing.
Only today, Google and Microsoft were granted patents for future use of handwriting recognition to be used in future computers, smartphones and smart watches that I will cover in future patent reports.
