A team of researchers from Germany's Hasso-Plattner Institute is trying to find an effective way to trick the mind into thinking a virtual object or wall is real. They have developed a new device that "sends little electric shocks to sensors on your arms that stimulate your muscles whenever you press against a wall or try to lift a heavy object in virtual reality," reports Motherboard. From the report: The team's main goal was to create this illusion as cheaply as possible. Their contraption, seen in the video above, consists of little more than an electric muscle stimulator stuffed in a backpack, the sensors, and a Samsung GearVR device accompanied by motion trackers. In other words, if you've been turned off by the clunky headsets of the contemporary VR experience, this probably won't do much to win you over.
