      The effects of system performance variations on people s estimation of virtual object sizes in a multi-sided back projection virtual reality system have been explored. Seventy-seven participants adjusted the sizes of three ...
    • Novel Shutter Glass Control for Simultaneous Projection and Picture Acquisition 

      Kunz, Andreas M.; Spagno, Christian P. (The Eurographics Association, 2001)
      Virtual reality offers completely new possibilities for collaborative work over distributed environments. To enable collaborative work, it is necessary that both, virtual objects as well as the other users, can be seen ...
    • On the Utility of Semantic Constraints 

      Smith, G.; Stuerzlinger, W. (The Eurographics Association, 2001)
      Content creation for computer graphics applications is a laborious process that requires skilled personnel. One fundamental problem is that manipulation of 3D objects with 2D user interfaces is very difficult for nonexperienced ...
    • Perception and Mental Rotation of 3D-Freeform Surfaces in an Immersive Projection System 

      Gaggioli, Andrea; Breining, Ralf (The Eurographics Association, 2001)
      This paper reports on three experiments performed to examine the effects of different visualization techniques of 3D computer-generated freeform surfaces on subjects perceptual and cognitive performance while doing ...
    • Presence a global media quality metric 

      Lessiter, J.; Freeman, J. (The Eurographics Association, 2001)
      In this paper presence (a sense of being there in a mediated environment) is proposed as a global quality metric with which to evaluate advanced multi-modal media systems. The development of a new presence selfreport ...
