项目摘要

Although comfortableness of clothing has been evaluated by a sensory inspection up to now, it is necessary to establish the method of the evaluation using an objective index. However, a quantitative evaluative method has not been established yet. Comfortableness can be evaluated by physiological reactions because they are related to feelings and emotions. Brain waves are one of the human physiological reactions. Analyzing brain waves is considered an effective method for evaluating feelings. Thereupon, we are planning to establish the objective evaluative method of comfortableness of clothing by measuring and analyzing brain waves. We evaluated thermal adaptation wearing clothing, the restraint of clothing, handling of clothing and fabrics and the likes and dislikes of food by analyzing brain waves.We used two methods of the analysis of brain wave. One was the α-wave power ratio and another was the emotion spectrum analysis method of electro-encephalogram (EEG). The emotion spectrum analysis method is based on the analysis of space and time series correlation of EEG.As for the α-wave power ratio and the emotion spectrum, there were large differences in the subjects. The α-wave power ratio of the uncomfortable conditions was smaller than that of the comfortable conditions. However, the difference was not significant. Though it is difficult to extract the factors that determine comfortableness or uncomfortableness from lots of unwanted information in brain waves, if experimental conditions are arranged, it is possible that such analysis can be used for the evaluation of the comfortableness of clothing.

迄今为止，虽然通过感官检查来评价服装的舒适度，但仍需要建立使用客观指标的评价方法。然而，尚未建立可以通过生理反应来评价舒适度的评价方法。脑电波是人类的生理反应之一，因此，我们计划通过测量和分析脑电波来建立服装舒适度的客观评价方法。。我们通过分析脑电波来评估服装的热穿着适应性、服装的约束力、服装和织物的处理以及食物的好恶。我们使用了两种脑电波分析方法，一种是α波功率比，另一种是α波功率比。脑电图情绪谱分析方法是基于脑电图的空间和时间序列相关性分析。α波功率比和情绪谱存在较大差异。的 α 波功率比。不舒服的情况比舒适的情况要小，虽然很难从脑电波的大量不需要的信息中提取出决定舒适或不舒服的因素，但如果有实验条件的话，是可以的。这种分析可能可以用于评估服装的舒适度。
