Smart boots can be lifesaver for astronauts. Researchers at MIT’s Man Vehicle Lab are working on boots and other wearables that give users feedback when obstacles are in their way. The wearer is warned with vibrations and sees the information using an augmented reality system.
As TechCrunch explains, these boots use range finders to let the wearer know how close they are from an unseen moon rock. As obstacles get closer, the frequency of vibrations increases.
