This thesis presents the developement of a foot controlled interface, which provides access to

computers for those people, who have diculties or are unable to use their upper limbs. The

users are able to controll and click with the cursor by moving their legs. The paper gives an

overview of the currently widespread human-computer interfaces, presents the technology

behind the brain-computer interface, the head-computer interface, which - depending on

the implementation - can be contolled by head movements or eye movements. Grants some

insight on the workings of speech recognition systems, the footmouse and presents the

experimental inductive tongue-computer interface. The foot controlled interface created

in this thesis provides a viable alternative for certain people using the beforementioned

interfaces. This paper descibes the design challenges and the chosen decisions for creating

the interface. Shows the step by step process of creating the interface in Matlab. Finally

compares the performance of the currently used interfaces and the newly created interface.
