Document Summary
Conceptual knowledge, i. e. what you know and believe to be true, can"t change what you perceive: seeing is believing (not the other way around) Perception, cognition, and action in an immersive multimodal environment populated with objects events and actors. Blend of virtual and real spaces with seams. Design constrained by science facts (note scare quotes) Designer capable of translating from science to design. Designer capable of translating from use to science, collaboration with scientists. The interaction between display characteristics and the information processing characteristics of the user"s perceptual, motor, and cognitive processes will largely determine interface performance. Weber"s law-the ratio of the increment threshold to the background intensity is a constant. So when you are in a noisy environment you must shout to be heard while a whisper works in a quiet room. And when you measure increment thresholds on various intensity backgrounds, the thresholds increase in proportion to the background.
