Navibelt, a belt for the blind.
This belt was designed to be a digital interface to guide blind people. It functions akin to if someone was holding a blind person by their hips and gently applying pressure in the direction they should walk. Also sort of similar to guiding someone by the hand, but with a low profile integrated wearable belt instead. This project needs to be revisited to slim the wiring and also couple to the appropriate perception system & direction planner, but at least this serves as a cheap effective machine to human interface mechanism for quickly communicating human movement direction intent.
