Christopher Heller, Michael Ruß and Theo Seemann finished their portation of Marioland on a 3D environment with real intuitive input devices – your own feet! The main aim was to produce a super natural interface. Thus the application, made in Jörg Frohnmayer’s VR-seminar with TCL and Lightning, uses tracking of your feet while you’re walking in front of a 3D Powerwall.
