SIGGRAPH has certainly been the home of many virtual reality demonstrations, and this year yet another contraption that (partially) removes us from the world we know will be on display. Similar to the Powered Shoes and Virtusphere seen in years past, the String Walker is a "locomotion interface that uses eight strings actuated by motor-pulley mechanisms mounted on a turntable" in order to let users walk through virtual landscapes. Proprioceptive feedback allows the VR system to translate actual footsteps into the digital world, giving participants a reason to stroll around rather than just twiddling their thumbs. Reportedly, the biggest challenge was mastering the floor, which enables omni-directional walking that simple "treadmill-like" surfaces don't offer and in a simpler fashion than the "complicated" CirculaFloor. Next-generation DDR, here we come.
