Design issues in human visual perception experiments on region warping

Virtual reality systems are primarily concerned with the presentation of realistic 3D graphics to the user. In light of the fact that the human visual system can only perceive a finite amount of detail, it is therefore possible to reach a balance in the tradeoff between human perception of detail and computational load required for rendering. Priority rendering is a technique designed to reduce the overall rendering load for an address recalculation pipeline virtual reality system. This system was developed to reduce user perceived latency during head rotations in head mounted display virtual reality systems. Large object segmentation and region warping were methods introduced to priority rendering in order to further enhance the overall rendering load reductions and to deal with various visual artefacts. This paper discusses the issues and considerations involved in designing human factors experiments concerning human perception to region warping.
