DOI: 10.1145/1178418.1178429We have designed and evaluated a novel multiplayer game system using just one top-view camera. With the proposed system, player avatar movement can be directly mapped to the physical movement of the player, accompanied by additional hand gestures triggering more complex actions. This article presents a study of the concepts of body-driven multiplayer games using the proposed system. We have created four different test games using human-centered design (HCD). We describe both the computer vision- based implementation and the lessons we learned about designing effective content for interactive body-driven multiplayer games.
