        A Holistic Model of the Face for Human Computer Interaction

Abstract:

Researchers in the field of HCI have already begun to build
experimental systems which react to facial nonverbal behavior (i.e.,
facial expressions, gaze, and pupil size).  However, much of this work
has suffered because the theoretical groundwork has yet to be
constructed.  I will first introduce a study which I did to
investigate the exhibition of facial expressions within HCI.  

This is the first experiment ever to show that humans actually do make
facial expressions when interacting with computers, and the number of
expressions is quantified across a variety of computer-based tasks
(i.e., graphical manipulation, graphical creation, text manipulation,
gaming, and a baseline) and user experience levels (i.e., novice,
intermediate, expert).  I will also review other psychological and HCI
literature relevant to the use of gaze and pupil size in HCI.
Finally, I will describe the beginning of a theoretical model which
uses all three of these input channels together, thereby reducing
ambiguity.  This model can be used to conduct "Wizard of Oz" studies
and build adaptive user interfaces using AI techniques.

Biography:

Mr. King completed a Bachelor of Arts in Experimental Psychology with
Honors and a Bachelor of Arts in Computer Science with Honors at
Southwestern University.  He will be entering the doctoral program in
cognitive psychology at the University of Washington in the fall; he
will also begin his duties as research assistant to Dr. Thomas A.
Furness at HITL.  Mr. King has previously spent two summers at HITL as
first an intern and then as a laboratory associate.  Beyond facial
non- verbal behavior, Mr. King's research interests include 3D sound
in HCI, psychological issues in multi-user virtual environments, and
adaptive user interfaces.
