Effect on Postural Sway of the Invasion to Preferable Interpersonal Distance

摘要

This paper proposed a methodology which allows the detection of characteristic postural sways which relate to the invasion to preferred interpersonal distance. The result of empirical study revealed that, at least in most cases under the condition of standing posture, the characteristic change points of postures which are caused by bodily sway can be identified based on the analysis of body pressure distribution using the biomechanical reference models. This methodology based on non-verbal behavior is also expected to be helpful to analyze problematic phenomena of the invasion to personal space of individuals who have the difficulties of linguistic behavior.
