Gamepads and joysticks will become a thing of the past if the latest idea for
controlling video games takes off. Called Virtual Ring, the system monitors the
movements of the player’s body and converts them into the actions of characters
in the game. To use Virtual Ring you stand on a platform facing the screen. A
set of motion sensors detects the movements of your arms and legs, and makes the
character on the screen punch and kick in unison. The device could prove popular
with fitness enthusiasts. Its Korean manufacturer, Bestsoft, claims that an
energetic session on Virtual Ring burns up nearly a third as many calories as
jogging.
