Know that feeling when someone wanders too far into your personal space? The University of Illinois' Victor Mateevitsi does, which is why he'd built a suit that does the job to a far greater degree of accuracy. SpiderSense is a onesie that uses a series of microphones to rend and receive ultrasonic signals from the space around you, like high frequency radar. When the outfit senses something approaching, a robotic arm corresponding to the microphone exerts pressure on your skin, pointing you in the direction of the danger. Mateevitsi tested the gear by blindfolding researchers and asking them to throw a cardboard ninja star whenever (and wherever) they sensed a threat -- with positive results 95 percent of the time. SpiderSense will get its first public showing at Stuttgart's Augmented Human conference in March and it's hoped that the hardware will eventually help Blind people get around easier.
