Navigation assistant for people with impaired vision or blindness

Prof. Patrick Slade
Assistant Professor of Bioengineering (Harvard Ability Lab)

We have developed a navigation system that overcomes all of these navigation challenges by combining novel computer vision techniques, sensor fusion, and personalized feedback to the user, requiring only a smartphone. We have provided extensive research testing to validate the mobility benefits and surveyed 99 potential users to understand the market fit.


Our system will provide the functionality of guide dogs at approximately 20 times lower cost, within the price range specified by the surveyed users, creating potential to dramatically increase the number of people that can benefit from navigation assistance. In addition, our system adds essential independent navigation capabilities to help people travel to new destinations and provide environmental scene understanding. We aim to improve the mobility and independence for millions of people with impaired vision
