I read an article the other day about using a very simple haptic glove to sense objects that someone cannot see. The use for this specific glove is rescue workers in floods that need to sense underwater objects. I thought this was pretty interesting and it reminded me of a Y-combinator hardware hackathon project that was a proof of concept of haptic technology. I think, using an ultrasonic range finding array, this could be a good proof of concept for the different glove ideas. Next year, I am trying to take a class in school called Projects in CS where you present an idea and then spend the semester working on it. Since this is a very limited timeframe, a simpler proof of concept project like this one could be perfect.
