In this presentaton, I will first describe our real-time
stereo face tracking and gaze detection system to measure
head pose and gaze direction simultaneously. The key aspect
of our system is the use of real-time stereo vision together
with a simple algorithm which is suitable for real-time
processing, and we achieved a non-contact, passive,
real-time, robust, accurate and compact measurement system
for head pose and gaze direction. Then as an application of
the measurement system, the wheelchair system which have an
intuitive interface using head and gaze motion of a
user. The user needs only to look where he/she want to go,
and can start and stop by nodding and shaking his/her
head. The system also estimates whether the user is
concentrated on the operation based on the relationship
between the head and gaze movement. The feasibility of the
developed wheelchair system is confirmed through experiments
in both indoor and outdoor environments.
