The idea for my project is to create shoes for the blind that have an array of proximity sensors that can detect obstacles in front of them. The sensors would connect to vibrating pads in the wearers shoes. When obstacles appear, but pads would give the wearer a general sense of what lies in front of them. Challenges would include calibrating the proximity sensors and vibrators to actually make the device useful, as well as making a product slim and durable enough that it could be worn daily.
