"A Taste of Vision for Those without Sight": Abstract

The restoration of vision to those who are completely blind is being aggressively pursued on a worldwide scale. Retinal implant chips and cortical implant electrodes are the most common strategies for trying to re-establish sight.
Sensory substitution refers to the use of an intact sense as a conduit for relaying information to the brain via an alternative sensory channel. This is a relatively novel strategy which may provide a means for restoring a sense of one’s environment (vision) to the blind.
 
The Brainport is a novel sensory substitution device which uses the tongue and a camera as a paired substitute for the eye. By converting a live video stream into an electrotactile display worn in the mouth, users are able to successfully interpret the sensation, much as the fingertips can be used to interpret symbols when reading Braille.
 
Current assistive devices for the blind have their primary functionality in text identification, however there is a critical need to provide the blind community with methoAmy Nau and Justin Crowley ds to enhance wayfinding and object identification.
We have demonstrated that the Brainport is able to allow completely blind individuals to perceive features of their immediate environment, including object identification as well as basic wayfinding skills. We have also shown that modified psychophysical tests are reliably able to measure how well the device is working. Our results, as well as implications for neuroplasticity will be discussed in this lecture.
