Brief description of this line of research
Most low cost eye typing systems are based on webcams and present important disadvantages such as limited accuracy and lack of robustness. Our aim is to build an accurate and robust eye typing system where visible light is used to produce a corneal reflection which serves as a reference point for subsequent measurements in the eye. Very few attempts, if any, have been made to use visible light in corneal reflection approaches to the problem of eye tracking. The reasons usually given to justify the limited application of this type of illumination are that the required image features are less accurately depicted, and that visible light may disturb the user. Despite these difficulties, we will show that it is possible to track eye movements in these circumstances allowing large head displacements and without need of recalibration.
