Human visual perception is one of the major factors in virtual environments. It can be evaluated through numerous variables and datasets. In this talk we present our current work on evaluation of the perception of volumetric datasets under combinations of conditions of virtual environments, such as head tracking, stereoscopic display, and different navigation techniques, and of volumetric rendering variables, such as alpha, transfer function, transparency and density. We will discuss the complexities of this design space, our current plan for experimental evaluation and the results from an informal pilot study.
