Summary

The proposed project seeks to provide object recognition as a feature in a retinal implant system. Participants will be able to direct an object recognition application to find a desired object in the field of view of the head-mounted camera, and to direct the participant's view towards it through the presentation of a recognizable icon. A prototype system will be developed and evaluated in human subjects in phase I. A full system implementation and a second phase of the trial will be completed in phase II.
