Abstract: Disclosed herein are systems and methods for distributed computing and/or networking for mixed reality systems. A method may include capturing an image via a camera of a head-wearable device. Inertial data may be captured via an inertial measurement unit of the head-wearable device. A position of the head-wearable device can be estimated based on the image and the inertial data via one or more processors of the head-wearable device. The image can be transmitted to a remote server. A neural network can be trained based on the image via the remote server. A trained neural network can be transmitted to the head-wearable device.

Abstract: Techniques are described for inspecting optical devices, such as eyepieces, to determine whether they exhibit light leakage through an edge sealant that has been applied to the device. Embodiments provide an inspection apparatus that can be employed to detect the leakage of light through an edge sealant of an optical device, where the edge sealant is applied to prevent, or at least reduce, the leakage of light from the optical device. Light from a light source is projected into the optical device. The light can travel along one or more wave guides within the device, until reaching an edge of the device. Light that is able to leak through an edge sealant can be reflected, using mirror(s) in the apparatus, and detected by a camera. Image(s) captured by the camera can be analyzed to determine the performance of the optical device with respect to edge leakage.

Abstract: An example head-mounted display device includes a light projector and an eyepiece. The eyepiece includes a light guiding layer and a first focusing optical element. The first focusing optical element includes a first region having a first optical power, and a second region having a second optical power different from the first optical power. The light guiding layer is configured to: i) receive light from the light projector, ii) direct at least a first portion of the light to a user's eye through the first region to present a first virtual image to the user at a first focal distance, and iii) direct at least a second portion of the light to the user's eye through the second region to present a second virtual image to the user at a second focal distance.

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: 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: Techniques are disclosed for performing localization of a handheld device with respect to a wearable device. At least one sensor mounted to the handheld device, such as an inertial measurement unit (IMU), may obtain handheld data indicative of movement of the handheld device with respect to the world. An imaging device mounted to either the handheld device or the wearable device may capture a fiducial image containing a number of fiducials affixed to the other device. The number of fiducials contained in the image are determined. Based on the number of fiducials, at least one of a position and an orientation of the handheld device with respect to the wearable device are updated based on the image and the handheld data in accordance with a first operating state, a second operating state, or a third operating state.
