GAZE TRACKING FOR ONE OR MORE USERS

摘要

One or more techniques and/or systems are provided for gaze tracking of one or more users. A user tracking component (e.g., a depth camera or a relatively lower resolution camera) may be utilized to obtain user tracking data for a user. The user tracking data is evaluated to identify a spatial location of the user. An eye capture camera (e.g., a relatively higher resolution camera) may be selected from an eye capture camera configuration based upon the eye capture camera having a view frustum corresponding to the spatial location of the user. The eye capture camera may be invoked to obtain eye region imagery of the user. Other eye capture cameras within the eye capture camera configuration are maintained in a powered down state to reduce power and/or bandwidth consumption. Gaze tracking information may be generated based upon the eye region imagery, and may be used to perform a task.

1. A system for gaze tracking, comprising:
a gaze tracking component configured to:
utilize a user tracking component to obtain first user tracking data for a first user at a first time T1;evaluate the first user tracking data to identify a first spatial location of the first user at the first time T1;select a first eye capture camera from an eye capture camera configuration based upon the first eye capture camera having a first view frustum corresponding to the first spatial location, the eye capture camera configuration comprising a plurality of eye capture cameras having a fixed view frustum configuration;invoke the first eye capture camera to obtain first eye region imagery of the first user at the first time T1; andgenerate first gaze tracking information for the first user at the first time T1 based upon the first eye region imagery.
