Abstract: A sensory eyewear system for a mixed reality device can facilitate user's interactions with the other people or with the environment. As one example, the sensory eyewear system can recognize and interpret a sign language, and present the translated information to a user of the mixed reality device. The wearable system can also recognize text in the user's environment, modify the text (e.g., by changing the content or display characteristics of the text), and render the modified text to occlude the original text.

Abstract: An eyepiece for an augmented reality display system. The eyepiece can include a waveguide substrate. The waveguide substrate can include an input coupler grating (ICG), an orthogonal pupil expander (OPE) grating, a spreader grating, and an exit pupil expander (EPE) grating. The ICG can couple at least one input light beam into at least a first guided light beam that propagates inside the waveguide substrate. The OPE grating can divide the first guided light beam into a plurality of parallel, spaced-apart light beams. The spreader grating can receive the light beams from the OPE grating and spread their distribution. The spreader grating can include diffractive features oriented at approximately 90° to diffractive features of the OPE grating. The EPE grating can re-direct the light beams from the first OPE grating and the first spreader grating such that they exit the waveguide substrate.

Abstract: An eyepiece waveguide for an augmented reality. The eyepiece waveguide can include a transparent substrate with an input coupler region, first and second orthogonal pupil expander (OPE) regions, and an exit pupil expander (EPE) region. The input coupler region can be positioned between the first and second OPE regions and can divide and re-direct an input light beam that is externally incident on the input coupler region into first and second guided light beams that propagate inside the substrate, with the first guided beam being directed toward the first OPE region and the second guided beam being directed toward the second OPE region. The first and second OPE regions can respectively divide the first and second guided beams into a plurality of replicated, spaced-apart beams. The EPE region can re-direct the replicated beams from both the first and second OPE regions such that they exit the substrate.
