This paper describes a 3D, tangible user interface system and related
interaction techniques for a CAVE environment. The developed
system is based on off-the shelf software and hardware component
to provide 3D input data for applications. A CAVE installation
with four sides (three walls and a floor) is used as a display and
interaction space. Interaction tasks (navigation, selection, manipulation)
are performed using interaction techniques based on manipulation
of physical objects (props). All virtual objects are directly
manipulated using the corresponding props to which AR physical
markers are attached. Each physical marker corresponds to a specific
virtual object. The floor projection (a white rectangle overlaid
on top of the application generated video stream) or a directional
light is used to create illumination necessary for computer vision
based marker detection using ARToolKit. Initial evaluation results
are positive and provide directions for future research.
