'Virtual' Guide Dog for Visually Impaired Navigation
From: Medcial Design Briefs - 04/30/2016

Wearable device miniaturized for easier use.

A team of computer scientists at MIT has developed a low-power chip to
process 3D camera data that, they say, could aid visually impaired people
navigate their environments. The chip consumes only one-thousandth as much
power as a conventional computer processor executing the same algorithms.

Using their new chip, the team built a prototype of a complete navigational
system. The system is roughly the size of a binoculars case and is worn
around the neck. It uses an experimental 3D camera from Texas Instruments.
The user carries a mechanical Braille interface that was developed at MIT's
Computer Science and Artificial Intelligence Laboratory, which conveys
information about the distance to the nearest obstacle in the direction that
the user is moving.
