Control of a Powerpoint Presentation Using Eye Movements

The purpose of this paper is to present a system capable of helping a person to control the slide shows during his/her presentation without the use of his/her hands. In fact, a particular movement in the eye will allow a change in the slide (towards the next or the previous slide). To do so, some electrodes were used in order to record the eyes movements and some electronic circuits as well as a microcontroller were deployed for recognizing the eye movement signal from the noise in order to limit any faulty signal. A wireless signal is sent to the computer in order to move the presentation up or down. The system was tested on several persons while taking into consideration the age, the skin color, the fatigue, the quantity of light, the use of glasses / medical lenses and the results were very promising especially with the hitting percentage that reached more than 90%, which means, in other words, that the error percentage was less than 10%.
