Physiological Limits of Human Visual Perception in Virtual Environments
Computing Systems for Human Benefits: Proceedings of the 8th International Conference on Work With Computing Systems (Stockholm 2007), page 253–257. Stockholm, Royal Institute of Technology, (2007)Abstract
This contribution is concerned with considering physiological factors of human visual perception in the design of work systems using virtual environments. It starts with a description and analysis of physiological factors of monocular and binocular visibility mechanisms that influence the visual perception of the human being and that must be given thoughtful attention to in virtual environments additionally to technological parameters such as the screen resolution and the refresh rate of the projection of a virtual environment or the accuracy of calibration. As it is still difficult to estimate the complex interaction of these physiological factors, essential individual effects of visual depiction and human visual perception were analysed under ergonomic aspects in an empirical case study. The results of the presented study prove that the subjects’ distance to the projection screen and the degree of decoupling of accommodation and vergence have a statistically significant influence on their distortion of depth perception. Additionally subjects’ experience with three-dimensional visualization was identified as a further influencing factor.
