Resumo

VisiUMouse is a solution that enables accessibility to computer’s use by people with upper limbs motor disability. This Assistive Technology uses the concepts of Computational Vision to recognition and face tracking, using the eye as reference point. Through video input, that tracks the eye movement, we control the mouse cursor by webcam, providing an amplification in the functional abilities of these users and, consequently, promoting inclusion. The VisiUMouse was evaluated following the Fitts’s law protocol, which involves common pointing, select and click tasks, used as metrics to verify interaction with the computer.
