An adaptative visual device to assist patients affected by visual scotoma

The presence of a central visual scotoma disrupts recognition and any visual identification. The current visual apparatus (lens) obliges the patient to develop a new referential visual to investigate differently the visual information but regrettably they are not very successful. In this project, we elaborated an innovative adaptive optical device. Adaptive, because it is no longer the patient who has to adapt himself to his handicap but the device which is going to adapt its environment to his visual needs in real time. We suggest synchronizing eye movement and availability of the visual information by unmasking the visual information present under the scotoma. Our result shows that the subject is disrupted during the reading with the presence of the scotoma when more than 6 letters are masked. Beyond, we improve significantly the speed of reading according to the unmasking principle.A new proposal for the unmasking of information by respecting the cognitive and linguistic cues of the text is the object of the continuity of this project.
