Abstract: An optical assembly is disclosed in which two input pupils of light are projected onto an input grating. The input pupils can be overlapping or non-overlapping. The input grating is configured to receive the input pupils and to diffract them so that they are coupled towards an output element in parallel directions that are laterally separated from one another. The input pupils can be received respectively at a first portion and a second portion of an output element, on either side of a dividing line. The input pupils are received at positions that are symmetrically displaced from the dividing line. The first portion and the second portion are mirror-images of one another, and each can expand light from respective input pupils in an equal and opposite way.

Abstract: A waveguide for use in an augmented reality or virtual reality display comprises a plurality of optical structures in or on a photonic crystal. The plurality of optical structures are arranged in an array to provide two diffractive optical elements overlaid on one another in the waveguide. Each of the two diffractive optical elements is configured to receive light from an input direction and couple it towards the other diffractive optical element which can then act as an output diffractive optical element, providing outcoupled orders towards a viewer. The plurality of optical structures have different respective cross sectional shapes, for a cross section parallel to the plane of the waveguide, at different positions in the array in order to provide different diffraction efficiencies at different positions in the array.

The marketability service module of the system server employs a marketability algorithm to determine how marketable a user is based on self-reported work experience and skills for a job. The career path module employs a career path algorithm to provide to the user a prediction of a most successful path from a users current position to a destination position on the basis of a career paths database of transitions provided by a career path analyzer of a batch computing platform intermittently in communication with the career paths database.

Abstract: Methods for generating and displaying images associated with one or more virtual objects within an augmented reality environment at a frame rate that is greater than a rendering frame rate are described. The rendering frame rate may correspond with the minimum time to render images associated with a pose of a head-mounted display device (HMD). In some embodiments, the HMD may determine a predicted pose associated with a future position and orientation of the HMD, generate a pre-rendered image based on the predicted pose, determine an updated pose associated with the HMD subsequent to generating the pre-rendered image, generate an updated image based on the updated pose and the pre-rendered image, and display the updated image on the HMD. The updated image may be generated via a homographic transformation and/or a pixel offset adjustment of the pre-rendered image.
