Smart image processing system for retinal prosthesis.

Retinal prostheses for the blind have demonstrated the ability to provide the sensation of light in otherwise blind individuals. However, visual task performance in these patients remains poor relative to someone with normal vision. Computer vision algorithms for navigation and object detection were evaluated for their ability to improve task performance.

A wearable system for the visually impaired.

We present a light-weight, cheap and low-power, wearable system for assisting the visually impaired in performing routine mobility tasks. Our system extends the range of the white cane by providing the user with vibro-tactile cues corresponding to the location of obstacles and a safe path for traversal through a cluttered environment. The presented approach keeps cognitive load to a minimum, and while being autonomous, adapts to the changing mobility requirements of a navigating user.
