摘要： Systems and methods are described for determining a material of an object using sound. Exemplary methods employ a head-mounted display (HMD). In an embodiment, the method includes determining, using a depth camera function of the HMD, a distance to an object; emitting, using a speaker of the AR HMD, a generated sound signal; and responsive to emitting the sound signal, detecting a reflected sound signal. Relative to the emitted sound signal, the HMD determines attenuation levels for a temporal portion of the reflected sound signal for at least two frequency ranges of the reflected sound signal, the temporal portion of the reflected sound signal corresponding to a computed round-trip travel time of the sound signal traveling the determined distance to and from the object. Based upon the determined attenuation levels, the HMD determines a material corresponding to the attenuation levels.

摘要： Systems and methods are described for estimating a direction of interest of a user. In some embodiments, a method of estimating a direction of interest of a user includes tracking a head orientation of the user, detecting a shift in the head orientation, determining a head rotation rate during the shift in the head orientation, and estimating the direction of interest of the user based at least in part on the head rotation rate.

摘要： Systems and methods described that provide for sending a first temporal portion of video to a client, wherein video quality of a first spatial region associated with a first direction of view is sent with higher quality than video data for another spatial region not associated with the first direction of view; sending a second temporal portion of the video to the client; and responsive to determining that a significant event, audio or video or a combination, occurred during the second temporal portion and corresponds with a second direction of view that is associated with a second spatial region, sending higher quality video for the second spatial region than video data for another spatial region. Virtual reality (VR) video, including 360-degree VR video may thus be foveated, based on contextual information in the video data and corresponding audio data, combined with field of view predictions based upon user motion.

摘要： Systems and methods are described for determining positions of indoor localization beacons without requiring a physical site survey. In a coarse positioning method, a mobile node receives beacon signals that identify rooms (such as stores in a shopping mall) in which the beacons are located. The mobile node obtains floor plan information relating to the building and estimates beacon locations based on the floor plan and beacon signal strength. The estimated beacon locations may be arranged in a predetermined geometric pattern based on the number of beacons in a room. In a fine positioning method, a mobile node recognizes its proximity to a beacon and responsively measures the distance to other beacons. Estimated beacon positions may be used to estimate the location of the mobile node using trilateration or other techniques.
