| Abstract |
An affordance in ecological perception is the functional utility of any environment for a person with certain action capabilities. Specifically, it is the combination of environmental properties that supports some activity for a particular person. Affordances are thereby based in material properties of person and environment and they are perceived. The central hypothesis of this study is that perceptual judgement on interior space reflects the underlying dynamics of activity in the person-space system, specifically that perceptual category boundary for certain activity corresponds to actual critical point. Second, this percieved point is constant over body scale changes in the system. This parallelism between perception and action implies that predictions can be made about action performance from an analysis of the perceptual judgement. In the case of living room and bed room size, this means that the perceptual category boundaries between "livable" and "unlivable" should correspond to ciritical height and width of the rooms, as estimated from the action in real spaces, and that these values should be constant across different human body size. In this study an experiment with interior space models of reduced scale was tried by varying the living room height and bed room width with respect to two statures in order to test the hypothesis that perceptual judgement are based on body-scaled information specifying room height and width as a ratio of the body size. We conclude (a) that the critical point of living room height occurs at π=0.89, (b) that the critical point of bed room width was not discovered, and (c) that the perception of room height is based on body-scaled information. The results of this study suggest an ergonomically sound design recommandation of 210cm as a minimum for livingroom height of apartment house in Korea. |
