Human face tracking (HFT) is one of several technologies useful in vision-based interaction (VBI), which is one of several technologies useful in the broader area of perceptual user interfaces (PUI). In this paper we motivate our interests in PUI and VBI, and describe our recent efforts in various aspects of face tracking in the Interaction Lab at UCSB. The HFT methods (GWN, EHT, and CFD), in the context of VBI and PUI, are part of an overall “TLA approach ” to face tracking. TLA /T-L-A / n. [Three-Letter Acronym] 1.
