Publication number: 20240146897Abstract: An eye tracking system includes a pair of glasses including two frames, a projector coupled to the pair of glasses and operable to project a beam of light, and an eyepiece mounted in one of the two frames and optically coupled to the projector. The eyepiece is operable to direct at least a portion of the beam of light towards an eye of a user. The eye tracking system also includes one or more optical sensors coupled to at least one of the two frames of the pair of glasses and operable to detect a set of reflected signals off the eye of the user, and a processor coupled to the projector and the one or more optical sensors, wherein the processor is operable to determine an eye orientation based on the set of reflected signals.Type: ApplicationFiled: October 24, 2023Publication date: May 2, 2024Applicant: Magic Leap, Inc.Inventors: Brian T. Schowengerdt, Mathew D. Watson, Samuel Scott Frank, Charles David Mellvile

Patent number: 11838496Abstract: An eye tracking system includes a pair of glasses including two frames; a light scanning projector coupled to the pair of glasses and operable to scan a beam of light to project an image frame including a plurality of pixels; an eyepiece mounted in one of the two frames and optically coupled to the light scanning projector; one or more photodetectors coupled to one of the two frames and operable to detect time-varying reflected signals; and a processor coupled to the light scanning projector and the photodetectors. The eyepiece includes an exit pupil expander operable to direct a portion of the beam of light towards an eye of a user. Each of the time-varying reflected signals is associated with the plurality of pixels. The processor is operable to correlate the time-varying reflected signals with the plurality of pixels and determine a first eye orientation.Type: GrantFiled: May 3, 2021Date of Patent: December 5, 2023Assignee: Magic Leap, Inc.Inventors: Brian T Schowengerdt, Mathew D. Watson, Samuel Scott Frank, Charles David Melville

Patent number: 11460628Abstract: A waveguide display system may include an eyepiece waveguide that can have a first surface and a second surface, the waveguide including an incoupling diffractive optical element (DOE) and an outcoupling DOE. The waveguide display system may include a light source and a scanning mirror, and may include reflective and collimating optical elements. The incoupling DOE can be configured to selectively propagate incident light beams to the outcoupling DOE in the waveguide through total internal reflection (TIR).Type: GrantFiled: March 24, 2021Date of Patent: October 4, 2022Assignee: Magic Leap, Inc.Inventors: Brian T. Schowengerdt, Mathew D. Watson, Steven Alexander-Boyd Hickman, Charles David Melville, Samuel Scott Frank
