Tangible devices for two handed 3D interaction

Tangible devices, two handed interaction and colocation are well known concepts in the 3D user interface community. Many researchers believe that these concepts can improve the quality of interaction and enhance the sensation of presence in a virtual environment. In this workshop contribution we show how we have integrated these concepts in the Personal Space Station (PSS), a near field desktop VR/AR environment. We review the governing principles and enabling technology of these concepts, and discuss our observations of interaction styles in the PSS.
