This paper presents three methods for classifying and qualifying virtual and immersive environments. The first is to plot modes of use against environment types. The second is to create a matrix analyzing display type against interaction methodology. The third is to analyze the system as if it created a volume of 3D pixels and determine if the quality of the created pixel volume is appropriate for the given application and use.
