Cheap sensors to improve your gaming experience

Video games like Dance Dance Revolution could soon require more than just fancy footwork. Small, cheap sensors for tracking the movement of a person’s entire body could lead to “whole-body interfaces” for controlling computers or playing games, researchers say.

Conventionally, motion capture makes use of reflective dots or small LEDs attached at key points on a person’s torso, limbs and head. Capturing the movements of these points using an array of cameras allows animators to create a computerized skeleton, which can then guide the movements of an animated character, for example.

However, “these systems need controlled situations to work” and typically cost tens of thousands of dollars, says Rolf Adelsberger of the Swiss Federal Institute of Technology (ETH) in Zurich. (link)
