    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 users 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 users eye through the second region to present a second virtual image to the user at a second focal distance.

    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: An eyepiece unit with optical filters includes a set of waveguide layers including a first waveguide layer and a second waveguide layer. The first waveguide layer is disposed in a first lateral plane and includes a first incoupling diffractive element disposed at a first lateral position, a first waveguide, and a first outcoupling diffractive element. The second waveguide layer is disposed in a second lateral plane adjacent to the first lateral plane and includes a second incoupling diffractive element disposed at a second lateral position, a second waveguide, and a second outcoupling diffractive element. The eyepiece unit also includes a set of optical filters including a first optical filter positioned at the first lateral position and operable to attenuate light outside a first spectral band and a second optical filter positioned at the second lateral position and operable to attenuate light outside a second spectral band.

    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.
