User Performance in VR Environments

This project is, in general, about understanding the effects of system characterics on user performance in different VR environments. VR technology has been increasingly used by scientific visualization applications. If we can predict and quantify the relative merits of different VR systems for different scientific visualization applications and tasks we would be able to utilize this relatively new technology in a more 'useful' manner. Although there is an increasing awareness among the researchers for the luck of it, very little has been done on the evaluation and comparison of user performance between different VR systems and it's implications about the VR system charactericstics.
