电动按摩椅按摩模式对舒适度影响的试验研究

Experimental study on the effect of massage mode on comfort of electric massage chairs

舒适度是电动按摩椅设计中最重要的考量指标。然而,目前对舒适度的评价方法大多存在缺陷,如传统的基于个体主观感受的舒适度评价方法存在个体感觉差异大的问题,其基于分析脑电或肌电信号的客观舒适度评价方法存在显著性不够问题。为此,特设计集主观评价和脑电信号客观分析评价为一体的评价试验,以阐述试验原理、方法和流程,并对试验结果进行统计分析。结果表明:按摩模式和按摩力度是影响舒适度的主要因素,在不同的性别间这种差异更加明显。该集成评价方法可为按摩模式与力度设计提供参考,从而提升按摩椅的舒适度。

Comfort is the most important evaluation indicator in the design of electric massage chairs. However, defects perplex most of the current methods for evaluating comfort. For example, the traditional comfort evaluation method based on individual subjective feelings varies greatly in individual perception. The objective comfort evaluation method based on analyzing EEG （electroencephalogram） or EMG （electromyography） signals lacks significance. For this reason, an evaluation test that combines subjective evaluation and objective analysis and evaluation of EEG signals comes into being. The paper introduces test prindples, methods and procedures, and then statistically analyze test results. The results show that massage mode and intensity are the main factors affecting comfort, and the difference is more obvious between different genders. The integrated evaluation method provides a reference for massage mode and intensity design, thereby improving the comfort degree of massage chairs.
