  • Electronic device with optical sensor for sampling surfaces
    Patent number: 12105897
    Abstract: A device such as a stylus may have a color sensor. The color sensor may have a color sensing light detector having a plurality of photodetectors each of which measures light for a different respective color channel. The color sensor may also have a light emitter. The light emitter may have an adjustable light spectrum. The light spectrum may be adjusted during color sensing measurements using information such as ambient light color measurements made with a color ambient light sensor that has a plurality of photodetectors each of which measures light for a different respective color channel. An inertial measurement unit may be used to measure the angular orientation between the stylus and an external object during color measurements. Arrangements in which the light emitter is modulated during color sensing may also be used. Measurements from the stylus may be transmitted wirelessly to external equipment.

  • Display system having sensors
    Patent number: 11217021
    Abstract: A mixed reality system that includes a head-mounted display (HMD) that provides 3D virtual views of a user's environment augmented with virtual content. The HMD may include sensors that collect information about the user's environment (e.g., video, depth information, lighting information, etc.), and sensors that collect information about the user (e.g., the user's expressions, eye movement, hand gestures, etc.). The sensors provide the information as inputs to a controller that renders frames including virtual content based at least in part on the inputs from the sensors. The HMD may display the frames generated by the controller to provide a 3D virtual view including the virtual content and a view of the user's environment for viewing by the user.

  • Light field capture
    Patent number: 10659757
    Abstract: This disclosure pertains to operations, systems, and computer readable media to capture images of a scene using a camera array and process the captured images based on a viewer's point of view (POV) for immersive augmented reality, live display wall, head mounted display, video conferencing, and similar applications. In one implementation, the disclosed subject matter provides a complete view to a viewer by combining images captured by a camera array. In another implementation, the disclosed subject matter tracks the viewer's POV as he moves from one location to another and displays images in accordance with his varying POV. The change of the viewer's POV is inclusive of movements in the X, Y, and Z dimensions.
