Tracking the wiimote in 3d using artoolkit

Abstract: Since its introduction in 2006, Nintendo’s Wii remote game controller (wiimote) has been used in many research projects. Most of the time however, only its accelerometer data is actually used. We present a system that allows 3D track-ing of the wiimote using its built-in camera, active IR markers and a modified ARToolkit library. Multiple markers are then discriminated by their blinking pat-terns. We conclude on using accelerometers to supplement optical tracking. 1 Introduction and Related Work In instrumented environments different interaction modalities are supported, such as interactive, direct-touch displays and tangible interaction. While these can facilitate many interactions in such environments, both have their drawbacks. Direct-touch dis-plays require users to physically reach the desired interaction area [R97]. If the data i
