It is argued that knowledge of cognitive psychology, and hence also of sensation and perception, one of its branches, is indispensable when one aims at improving our artificial environment. Four examples of sensation and perception studies are described. Firstly, an experiment was discussed to design a postal code format that can be used accurately in terms of the capacity of short-term visual memory. The second example describes a perceptual conflict between visual and bodily (kinesthetic/proprioceptive) sensations that arises as a result of wrongly designing buildings. In the third example it is shown that vibrotactual displays should present frequencies that trigger the Pacinian system in the skin if people have to make quick and accurate decisions. Finally, a study of a simple acoustic orientation system that can promote indoor travel and activity by blind people was described.
