Remote-controlled humans
Galvanic vestibular stimulation (GVS) isn't a new technology, but it's seeing some new application via Japan's NTT Communication Science Labs: remote-controlled people. They've developed a headphone apparatus that delivers an electrical current to a mastoid worn behind the ear, which actually shifts one's balance toward the anode. The stronger the applied current, the stronger the pull — strong enough to knock you off balance and alter the course of your movement. NTT is showing off the remote-controlling headphone system at SIGGRAPH, and has plans to commercialize the technology for use in gaming, and flight simulators. Oh, and, don't miss the video on this even though it's in Real format — you've never seen anyone so happy about being remote-controlled in your life.
