Abstract: A system may include finger devices. A touch sensor may be mounted in a finger device housing to gather input from an external object as the object moves along an exterior surface of the housing. The touch sensor may include capacitive sensor electrodes. Sensors such as force sensors, ultrasonic sensors, inertial measurement units, optical sensors, and other components may be used in gathering finger input from a user. Finger input from a user may be used to manipulate virtual objects in a mixed reality or virtual reality environment while a haptic output device in a finger device provides associated haptic output. A user may interact with real-world objects while computer-generated content is overlaid over some or all of the objects. Object rotations and other movements may be converted into input for a mixed reality or virtual reality system using force measurements or other sensors measurements made with the finger devices.

Abstract: In one implementation, a non-transitory computer-readable storage medium stores program instructions computer-executable on a computer to perform operations. The operations include obtaining first content representing a physical environment in which an electronic device is located using an image sensor of the electronic device. A physical feature corresponding to a physical object in the physical environment is detected using the first content. A feature descriptor corresponding to a physical parameter of the physical feature is determined using the first content. Second content representing a computer generated reality (CGR) environment is generated based on the feature descriptor and presented on a display of the electronic device.
