Abstract: A depth camera assembly (DCA) determines depth information within a local area. The DCA may selectively process a subset of data captured by an imaging sensor and obtained from the imaging sensor, such as pixels corresponding to a region of interest, for depth information. Alternatively, the DCA may limit retrieval of data from the imaging sensor to pixels corresponding to the region of interest from the imaging sensor for processing for depth information. The depth processing may include a semi-global match (SGM) algorithm, and the DCA adjusts a number of neighboring pixels used for determining depth information for a specific pixel based on one or more criteria. In some embodiments, the DCA performs the depth processing by analyzing images from different image sensors using left to right and right to left correspondence checks that are performed in parallel.

The seed users are placed in an initial tier of a tiered set of users for the sponsored content, and the additional users are placed in additional tiers of the tiered set of users based upon the determined scores such that each additional tier includes those users of the additional users having a specified range of determined scores, the tiers of the tiered set of users ranked according to the determined scores of users within each tier.

Abstract: Techniques are described for operating a display system comprising a light source and a scanning assembly. The light source includes a plurality of emitters arranged in a column and circuitry configured to drive the emitters based on image data. The scanning assembly includes a reflective surface facing the light source, the reflective surface being rotatable in at least one dimension. A control signal including periodic, non-linear pulses causes the reflective surface to rotate through a range of scan angles, thereby forming an output image based on reflection of emitted light. The image data is supplied to the light source in synchronization with the rotational movement of the reflective surface. Changes in rotation speed due to the non-linear nature of the control signal are compensated for by adjusting emission durations for different rows to provide different emission durations at different times based on changes in the linearity of the control signal.

Abstract: In one embodiment, a computing system accesses a three-dimensional (3D) model of an environment, the 3D model comprising a virtual representation of an object in the environment.

The computing system determines updated material parameters associated with the material property for the virtual representation of the object based on a comparison of the rendered pixels to corresponding pixels located in the image of the object.

Abstract: A system tracks eye position using a first Optical Coherence Tomography (OCT) eye tracking unit to determine a first position of an eye of a user. The OCT eye tracking unit projects low coherence interference light onto a portion of the user's eye, and uses captured light reflected from the illuminated portion of the user's eye to generate a dataset describing the portion of the user's eye. The first position of the user's eye is determined based upon the generated dataset and a previously generated dataset. In order to minimize error and reduce the effects of draft, a reference tracking system is configured to determine a second position of the user's eye, which is used to update the determined first position of the user's eye.
