Abstract

This paper introduces a new visual device concept for patients with partially sight loss named Visual Signal Adaptive Restitution (ViSAR). This new concept adapt the signal visual itself to the patient's visual discomfort in real time. While most device tends to compensate for physiology anomaly, ViSAR concept allows to improve the patient-signal interaction and to favor an active vision. This system is the first interacting with eye movements and adapting signal to patient cognitive behavior. Patients do not do anything, ViSAR adapts visual signal to patient's visual discomfort without changing visual and referential reflexes. This new concept involves at the same time engineer, ophthalmologic, optometric and cognitive competencies. ViSAR concept offers a new visual device generation satisfying the growing needs in assistance technology.
