SpaceHopper: Bounce Your Way to Galactic Domination.

Gaming with large displays can promote whole body interaction, social gameplay among acquaintances and strangers alike, and foster a sense of immersion. We present SpaceHopper, a large-scale, floor-projected version of the game Asteroids, where players bounce on a hopper ball to control their ship. We implemented two interaction modes: bounce to repel, which produces a 360º repulsion wave, and bounce to shoot, which fires a directional laser. Players bounce higher to generate a stronger wave, and bounce faster to fire more lasers. Perspective compensation is applied to the floor display, enabling the player to see the entire game field clearly regardless of their location on the floor.
