Victor Mateevitsi, a computer science student at the University of Illinois—Chicago, has developed a suit that gives you a "spider-sense." The core of the suit is a robot arm connected to a microphone module. Each module projects and receives ultrasonics, making it more like a bat-sense than anything else. If the module detects someone approaching, the robot arm places pressure on you to let you know what direction the "threat" is coming from.
