Publication number: 20240029218Abstract: According to examples, a system may use gaze direction information to perform tone mapping or chromatic adaptation for virtual reality (VR) environments. The system may include a processor and a memory storing instructions. When the processor executes the instructions, the system may determine a user focus location within a physical environment. An image corresponding to the physical environment may be received. The system may determine a visual property of the physical environment corresponding to the user focus location. The system may modify a color mapping of a region of the image based on the determined visual property to generate an output image.Type: ApplicationFiled: July 19, 2022Publication date: January 25, 2024Applicant: Meta Platforms Technologies, LLCInventors: Zhang JIA, Serhan ISIKMAN, Minchen WEI

Publication number: 20230359081Abstract: A display assembly with dielectric filters is presented herein. The display assembly includes a light source assembly, a dielectric filter array, and a modulation layer. The light source assembly generates laser light in multiple color channels, and each color channel is associated with a different laser emission spectrum. The dielectric filter array includes respective sets of reflective dielectric filters for each color channel. Each set of reflective dielectric filters is matched to the different laser emission spectrum such that reflective dielectric filters in each set transmit light in the different laser emission spectrum and reflect light outside of the different laser emission spectrum. The modulation layer is positioned between a first electrode layer patterned on the dielectric filter array and a second electrode layer. The modulation layer modulates light from the dielectric filter array based on emission instructions applied via the first and second electrode layers to form an image.Type: ApplicationFiled: April 25, 2023Publication date: November 9, 2023Inventors: Zhang Jia, Serhan Isikman, Yang Zhao, Donghee Nam, Rungrot Kitsomboonloha, Li Zhang

Publication number: 20230204506Abstract: A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.Type: ApplicationFiled: December 19, 2022Publication date: June 29, 2023Inventors: Chin San Han, Ueyn Block, Brian R.

Patent number: 10488936Abstract: This relates to a device that detects a user's motion and gesture input through the movement of one or more of the user's hand, arm, wrist, and fingers, for example, to provide commands to the device or to other devices. The device can be attached to, resting on, or touching the user's wrist, ankle or other body part. One or more optical sensors, inertial sensors, mechanical contact sensors, and myoelectric sensors can detect movements of the user's body. Based on the detected movements, a user gesture can be determined. The device can interpret the gesture as an input command, and the device can perform an operation based on the input command. By detecting movements of the user's body and associating the movements with input commands, the device can receive user input commands through another means in addition to, or instead of, voice and touch input, for example.Type: GrantFiled: February 6, 2015Date of Patent: November 26, 2019Assignee: Apple Inc.Inventors: Andrzej Baranski, Anna-Katrina Shedletsky, Kuldeep P.
