Problem: People who are blind and visually impaired face a huge number of mobility related head injuries.
Physical canes and sonar devices are useful, but provide limited information. Both are only measuring one point at a time.
A camera has multiple points and provides lots of informations, but unless you have stereo vision, the multiple points still do not measure depth. Without stereo vision, a pillar directly in front of you would be indistinguishable from a distance skyscraper.
The Digital White Cane delivers immediate data and depth from multiple directions simultaneously. This technology wasn’t possible before ToF LIDAR tech. In the past, LIDAR was as big as a truck and very expensive. We’ve created a lightweight and effective solution.
As 87% of the world’s blind live in developing countries (ref below), we endeavored to make a device that was inexpensive and easy to replicate. When produced on a mass scale, our device is projected to cost less than $30 for materials and assembly.
