We designed an alternative human-computer interface that has enhanced practicality and allows real-time interaction for persons with severe motor disabilities. The interface uses eye gazing as the main computer input device, allowing individuals to interact with computers by using only their eye movements. Eye coordinates are obtained with a remote eye-tracking system and then sent to a module where they are normalized into mouse coordinates according to the current monitor resolution. This work is novel because it simplifies the eye-tracking tech-nique to allow real-time and user-friendly interaction.
