    摘要： A system and method are disclosed for determining a depth map using TOF with low power consumption. In order to disambiguate, or de-alias, the returned distance(s) for a given phase shift, the system may emit n different frequencies of light over n successive image frames. After n frames of data are collected, the distances may be correlated by a variety of methodologies to determine a single distance to the object as measured over n image frames. As one frequency may be emitted per image frame, the depth map may be developed while consuming low power.

    摘要： Technology is described for reducing display update time for a near-eye display (NED) device. A point of focus in the NED field of view is identified, often based on natural user input data. A communication module of a computer system communicatively coupled to the NED device transmits lossless priority data, an example of which is user focal region image data, using one or more communication techniques for satisfying lossless transmission criteria. Allowed loss image data is identified based at least in part on its distance vector from a point of focus in the display field of view. An example of allowed loss image data is image data to be displayed outside the user focal region. The allowed loss image data is transmitted and extracted from received image data allowing for lossy transmission.
