Co-located interaction in virtual environments via decoupled interfaces

This paper describes an interaction style in virtual environments that allows co-located users to manipulate certain interactive features of virtual environments with 2D or non-inmersive types of input devices. The concept proposes to make interaction accessible to groups of users by mirroring some of the VE interaction characteristics and functionality and making them accessible from other types of input devices, such as Personal Digital Assistants (PDA), effectively de-coupling the interaction from the original forms and presenting the co-located users with a richer multimodal multi-device interaction mechanism.
