Drawing with the eyes and face

Recent work in eye tracking and facial expression analysis has enabled new forms of hands-free user interaction with computer applications. There has been particular emphasis on using these mechanisms individually for drawing and other artwork related applications (e.g. [Shugrina et al. 2006] [Hornof et al. 2004]).In this paper we explore the combination of the two modalities and describe a system for hands-free drawing that integrates the use of the eyes and the face as a means for user control. We present a general architecture for incorporating eye tracking and facial expression analysis into a computer application and utilize this architecture in the design and implementation of a drawing application.
