Joshua Miele of The Smith-Kettlewell Eye Research Institute is a blind scientist who has spent a quarter of a century developing new ways for blind people to access their world. His innovations allow people to navigate public transit systems and city streets through elegant audio/tactile maps, add rich audio description to YouTube videos and access information about businesses and other points of interest through a phone-based app. His guiding principles include using low-cost technology, crowd-sourcing the materials, and preserving user autonomy and participation.
