A virtual dance floor game using computer vision

Keyboard, mouse, and game controllers are common input devices for most computer games. Alternative devices are rarely used, restricting the player’s possible interaction with the virtual world. Computer vision techniques permit interaction with the computer that grants far more freedom than traditional devices, without the need of game-specific hardware and hindering cables. In this paper we describe a dance game where interaction is solely based on image analysis. A tracking system detects the position of the player’s feet in real-time. Two cameras are used and the foot positions are estimated in 3d from the two views. The player currently must have a marker attached to each shoe. Our evaluations show that depending on the markers, feet can be tracked accurately in real-time using a two-camera setup and an ordinary laptop computer. In further work we will extend the system to marker-less tracking. The system has been installed in a public museum and has been left in unsupervised mode for several months. 1
