The CAVESphere

To interact with our CAVE2 system, we are implementing well known techniques like classic wand devices, but we are also experimenting with less traditional ideas.
For instance, we successfully prototyped an intuitive object manipulation interface called CAVESphere, based on a plexiglass sphere with embedded tracking markers. The sphere also contains a camera and microphone, which we can use to detect finger taps on the sphere surface, providing simple touch input.
