| Outline of Final Research Achievements |
We developed a system that simulates phosphene, which is the perception of a spot of light, elicited by electrical stimulation on the visual cortex. The system generates a simulated phosphene image that would be perceived by the client in response to electrical stimulation applied by an electrode array on the cortex; the simulated image is based on previous physiological and clinical studies. The system is composed of a CMOS image sensor that has image processing circuits, a single board computer, and a head-mounted display. Taking advantages of its wearable feature, the system displays simulated phosphene images to the freely moving subject in real time. The system could be an effective tool for evaluating the level of vision that would be perceived by the client, and for designing a visual prosthetic system.
