Abstract
Human-computer interfacing (HCI) describes a system or process with which two information processors, namely
a human and a computer, attempt to exchange information. Computer-to-human (CtH) information transfer
has been relatively effective through visual displays and sound devices. On the other hand, the human-tocomputer
(HtC) interfacing avenue has yet to reach its full potential. For instance, the most common HtC
communication means are the keyboard and mouse, which are already becoming a bottleneck in the effective
transfer of information. The solution to the problem is the development of algorithms that allow the computer
to understand human intentions based on their facial expressions, head motion patterns, and speech. In this
work, we are investigating the feasibility of a stereo system to effectively determine the head position, including
the head rotation angles, based on the detection of eye pupils.
