Anthro-Centric Multisensory Interface for Vision Augmentation/Substitution (ACMI-VAS)

Abstract

During year four of the Anthro-Centric Multisensory Interface Vision Augmentation/Substitution (ACMI-VAS) project, the research team refined the integrated sensory substitution system for vision loss that mimics the function of the retina developed in year one. The ACMI-VAS concept uses a video camera connection to, or data from, a computer to represent, tactually, high-resolution narrow field, mid-resolution wider field and low-resolution 360 degree visual information simultaneously. We have integrated a method to enable identify colors tactually. We renewed approval for an experimental protocol to evaluate the testbed hardware and software against a single tactile display for human research participants (military and civilian) who have profound blindness. Tasks in the protocol include reading, visual acuity, web browser navigation, walking an obstacle course and identifying colors. Hardware elements have been updated to improve function and stimulus quality.
