Abstract

One of the most important information that may make it possible to analyse / evaluate the motion sickness incidence is subject's facial expressions during the whole-body exposure to low-frequency oscillations. Measurements of facial expression have to be carried out by means of non-invasive instruments.<BR>The authors used recorded video pictures for the analysis of facial expressions. After detailed observations of many records, they selected several parameters that were closely related to motion sickness incidence.<BR>Some statistical method such as multiple regression analysis, cluster analysis, etc. and fuzzy integral method with fuzzy measures were applied for the analysis of facial expressions.<BR>The authors show that analysis of facial expressions is possible and may give an effective tool for the evaluation of motion sickness incidence.
