IPC Code(s): A61F9/008
CPC Code(s): A61F9/00804
Abstract: eye safety and eye tracking accuracy is enhanced through pupil-aware eye tracking, where a fringe pattern projection or illumination onto the eye is locally dimmed in an area corresponding to the pupil. fringe projection local dimming is accomplished by modifying (locally dimming) the fringe pattern at the projector. illumination local dimming is accomplished at the light source (e.g., a laser source) before the light is provided by a micro-electromechanical system (mems) to the eye. an amount of light provided to non-pupil areas such as sclera may be increased to enhance a signal-to-noise ratio (snr), which may lead to more accurate eye tracking.

CPC Code(s): G03B21/2073
Abstract: a polarizing illuminator with light recycling includes a light source and a reflector disposed proximate one another. an assembly including a lens, a quarter-wave plate, and a reflective polarizer is configured to redirect the light at unwanted polarization back to the specific location of the reflector, which reflects the light back through the quarter-wave plate, enabling the light to be recycled. the lens collimates both the transmitted and the recycled light portions, providing well-defined light beams. the configuration allows the recycled light beam to be collimated and to propagate in a pre-determined direction, allowing targeted focusing of the recycled light onto pixels of a spatial light modulator.

Abstract: the present disclosure provides world-controlled augments and application-controlled augments. world-controlled augments can be controlled directly by a shell in the artificial reality environment. to allow even inexperienced users to develop world-controlled augments, a world-controlled builder system is provided. application-controlled augments may be resource intensive (e.g., using eye-tracking, social-media tie-ins, etc.), may support complicated interactions among themselves, may require or have extensive use of inputs and permissioned resources, and are controlled by their hosting application. when a running application is halted, the application closes its application-controlled augments but can choose to have the xr system run a “place-holder” world-controlled augment for as long as the application is not running. the place-holder world-controlled augment preserves the appearance of the application in the artificial reality environment but uses few system resources. upon a user selecting a place-holder world-controlled augment, the xr system can run the associated application and close the place-holder world-controlled augment.
