| Abstract: |  Video-based interfaces facilitate human-computer interaction for people
unable to use common input devices like keyboard or mouse,
e.g. due to a handicap or when the computer is physically separated from
the user (behind a glass, positioned too high).
The thesis describes the FCE system which behaves as a head-controled
mouse. Head movements are observed by a common low-cost web camera.
Face features are detected efficiently and tracked robustly, i.e. in a
manner that is insensitive to failure of certain detectors or trackers..
Location of tracked points are mapped to cursor position.
In tests, the proposed FCE system was evaluated by users as the most
efficient and user-friendly system of all single web camera systems
available on the WWW.
