A Head-Controlled User Interface ∗
Vincent Graveleau, Nikolay Mirenkov, G. P. Nikishkov · 2005
In this paper, we present an implementation of a head-controlled real-time human-computer interface that does not require using hands. This kind of interface may be valuable for disabled people or in cases where hands are busy with other tasks. Usual video-camera is employed for tracking head movements. Position of the eyes is determined with the use of image analysis. Head movements are mapped to cursor displacements. Nodding and head-shaking model left and right mouse clicks. Experiments show that the system behaves satisfactory even for usual web-camera frame rates (15fps), and small images (320×240). It consumes small percentage of CPU resources allowing other processes to run smoothly.
