This video demonstrates the operation of a virtual keyboard using a regular webcam and readings of the user’s head movement. The motivation is to design an input system for people with disabilities who cannot use a conventional mouse or keyboard.
The method presented in the video was further developed and its performance investigated in a study involving two groups (non-disabled participants and participants with disabilities). Further details in the corresponding paper1.
