Virtually enhancing the perception of user actions

Patrick Horain, José Marques Soares, Piyush Kumar Rai, André Bideau
2005 Proceedings of the 2005 international conference on Augmented tele-existence - ICAT '05  
Our approach consists in immersing the application in a virtual inhabited 3D space and mimicking user actions by animating avatars.  ...  This paper proposes using virtual reality to enhance the perception of actions by distant users on a shared application.  ...  A custom events server collects user actions on the shared application and forwards them to remote clients, which in turn locally animate avatars.  ...
