    Abstract: Systems and methods for image based location estimation are described. In one example embodiment, a first positioning system is used to generate a first position estimate. Point cloud data describing an environment is then accessed. A two-dimensional surface of an image of an environment is captured, and a portion of the image is matched to a portion of key points in the point cloud data. An augmented reality object is then aligned within one or more images of the environment based on the match of the point cloud with the image. In some embodiments, building façade data may additionally be used to determine a device location and place the augmented reality object within an image.

    Abstract: Systems and methods for device handshaking are described. Embodiments for client device and associated wearable device initiated handshaking are described. In certain embodiments, a device such as wearable camera eyeglasses having both high-speed wireless circuitry and low-power wireless circuitry communicates with a client device. The low-power wireless circuitry is used for signaling and to manage power on handshaking for the high-speed circuitry in order to reduce power consumption. An analysis of a high-speed connection status may be performed by a client device, and used to conserve power at the glasses with signaling from the client device to indicate when the high-speed circuitry of the glasses should be powered on.

    Abstract: Systems and methods for eyewear devices with integrated heads-up displays are provided. In one embodiment, an eyewear device provides an integrated heads-up display having a partially reflective element carried by an eyeglass lens to reflect towards the user computer-generated imagery projected on to it, while permitting the passage of light through the reflective surface in the direction of view of the user. The display mechanism further includes a cooperating projector assembly housed by a frame of the eyewear device in an overhead configuration relative to the partially reflective element. The projector assembly is housed by a top bar of the eyewear frame, with the reflective surface being housed wholly within the lens.
