In this demo, we use a multiplayer shepherding game to explore the possibilities of mutimodal, multiuser interaction with wearable computing in an intelligent environment. The game is centered around a table with a beamerprojected pastoral landscape. Players can use different intuitive interaction technologies (beamer, screen, HMD, touchscreen, speech, gestures) offered by the mobile and stationary computers. Building on our DWARF framework
, the system uses peer-to-peer, dynamically cooperating services to integrate different mobile devices (including spectators laptops) into the game.
