    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.

    Abstract: Head mounted display systems configured to project light to an eye of a user to display augmented reality image content in a vision field of the user are disclosed. In embodiments, the system includes a frame configured to be supported on a head of the user, an image projector configured to project images into the user's eye, a camera coupled to the frame, a waveguide optically coupled to the camera, an optical coupling optical element me, an out-coupling element configured to direct light emitted from the waveguide to the camera, and a first light source configured to direct light to the user's eye through the waveguide. Electronics control the camera to capture images periodically and farther control the first light source to pulse in time with the camera such that light emitted by the light source has a reduced intensity when the camera is not capturing images.

    Abstract: A head mounted display system configured to project light to an eye of a user to display augmented reality images can include a frame configured to be supported on a head of the user, a camera disposed temporally on said frame, an eyepiece configured to direct light into said user's eye to display augmented reality image content to the user's vision field, a reflective element disposed on the frame, and at least one VCSEL disposed to illuminate said eye, wherein the camera is disposed with respect to the reflective element such that light from the VCSEL is reflected from the user's eye to the reflective element and is reflected from the reflective element to the camera to form images of the eye that are captured by the camera.
