Design issues in virtual environment displays: a formal appraisal from the perspective of human perception

A pragmatic approach is required in the design of virtual environment displays. Successful design relies on technological development, but design must also consider the physiology and perception of the human user. When creating a virtual environment display, designers must therefore determine the exact VE task requirements. A human-centred approach must then be adopted to ensure that the display meets known human factor constraints, whilst a task-specific approach must formally appraise the perceptual and physiological demands required by the environment in order to maximise system performance whilst minimising problems to the human user.
