I love creating systems which break new ground. Lucky for me, an amazing sensory system for navigating as a blind person already exists. It's essentially what bats do, a kind of echo location, mastered by the guru, Daniel Kish. Flash Sonar is the name Daniel coined, in which you make sharp clicks with your tongue and listen to how the sound echoes off objects to figure out their size, shape, and distance. Most blind people have learned to do this to some degree, but it’s passive and not developed with a conscious process.
