Patent number: 12196964Abstract: An electronic device such as a head mounted device may have a head-mounted support structure. A portion of the head-mounted support structure may form a transparent housing member through which real-world objects can be viewed from eye boxes. A display system for the head-mounted device may have a display device that provides image light to a waveguide and may have an output coupler that couples the image light out of the waveguide toward the eye box. Peripheral portions of the transparent housing member or other peripheral device structures may be provided with a peripheral display that emits diffuse light into a user's peripheral vision. The peripheral display may use light guide structures, light sources, reflective structures, and other structures that provide transparency to real-world light.Type: GrantFiled: June 29, 2020Date of Patent: January 14, 2025Assignee: Apple Inc.Inventors: Austin S.

Publication number: 20250013292Abstract: Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.Type: ApplicationFiled: September 24, 2024Publication date: January 9, 2025Applicant: Apple Inc.Inventors: Wesley W.

Publication number: 20230333377Abstract: A display system includes a head-mounted display unit and a wake control system. The head-mounted display unit provides content to a user and is operable in a low-power state and a high-power state that consumes more power to provide the content to the user than the low-power state. The wake control system determines when to operate in the high-power state. The wake control system may assess a first wake criterion with low power, assess a second wake criterion with higher power than the first wake criterion upon satisfaction of the first wake criterion, and cause the head-mounted display unit to operate in the high-power state upon satisfaction of the second wake criterion.Type: ApplicationFiled: June 22, 2023Publication date: October 19, 2023Inventors: Fletcher R.

Patent number: 11029521Abstract: A head-mounted device may have a transparent display. The transparent display may be formed from a display unit that provides images to a user through an optical coupler. A user may view real-world objects through the optical coupler while control circuitry directs the transparent display to display computer-generated content over selected portions of the real-world objects. The head-mounted display may also include an adjustable opacity system. The adjustable opacity system may include an adjustable opacity layer such as a photochromic layer that overlaps the optical coupler and a light source that selectively exposes the adjustable opacity layer to ultraviolet light to control the opacity of the adjustable opacity layer. The adjustable opacity layer may block or dim light from the real-world objects to allow improved contrast when displaying computer-generated content over the real-world objects.Type: GrantFiled: March 13, 2019Date of Patent: June 8, 2021Assignee: Apple Inc.Inventors: David A. Kalinowski, Hyungryul Choi, Jae Hwang Lee
