The attention tracking function is achieved by utilizing OpenFace( https://github.com/TadasBaltrusaitis/OpenFace ) face pose estimation, Get Face Pose w.r.t. head_neck system and PBVS method, which we control the robot by inverse kinematic derivation w.r.t. desired attention position in the world coordinate reference. serial and sprotocol related files are created by Duo (https://www.linkedin.com/in/duoluthedeveloper/, who is a Ph.D. student in CIDSE, ASU).
