In late 2010, Wicab, Inc. announced receipt of a grant for $3.2M from the Defense Medical Research and Development Program to evaluate and improve the BrainPort vision device with help from veterans who lost sight on the battlefield. World-class collaborators include co-PI

affiliated faculty member Amy Nau, OD (pictured), director of optometric and low vision services and an assistant professor, the UPMC Eye Center, department of ophthalmology, University of Pittsburgh, and research collaborator, The Louis J. Fox Center for Vision Restoration of UPMC Eye Center, who will oversee human subject testing and outcomes assessments.
"We're at a critical stage in the research," Dr. Nau said. "But we want to move past researching. The hope is that we can eventually restore vision."
Wicab’s BrainPort vision device enables perception of visual information using the tongue and camera system as a paired substitute for the eye. Visual information is collected from a video camera and translated into gentle electrical stimulation patterns on the surface of the tongue. Users describe it as pictures drawn on their tongue with champagne bubbles. With training users may perceive shape, size, location, and motion of objects in their environment. The BrainPort vision device is intended to augment rather than replace other assistive technology such as the white cane or guide dog.
Researchers are hopeful the BrainPort device could become a bridge to independence for patients who lose sight. Dr. Nau is careful to not call BrainPort a quick fix; patients must train their brains to accept and interpret the images, she said.
The BrainPort vision device was developed by the late Dr. Paul Bach-y-Rita, a University of Wisconsin-Madison neuroscientist. The technology is covered by patents held by the Wisconsin Alumni Research Foundation ("WARF") and is exclusively licensed to Wicab. The BrainPort vision device is currently an investigational device and is not available for sale. Wicab Inc. is pursuing additional funding to support FDA clearance and commercialization. Wicab Inc. is a biomedical engineering company in Middleton, WI.
