基于表面肌电信号分析的电竞椅舒适性研究

Research on the Comfort of E-sports Chair Based on Surface EMG Signal Analysis

本文以电子竞技椅的舒适性为切入点,要起到得给久坐的人们缓解疲劳的效果,电竞椅的舒适性就显得格外重要,本文以此为研究目的通过人们使用电竞椅时的表面肌电信号分析并研究电竞椅的舒适性,运用双导肌电测量仪器对电子竞技椅使用者的表面肌电信号数据进行分析研究。通过对肩部斜方肌、腰部竖脊肌、手臂三角肌、肱三头肌、腿部腓肠肌、股外侧肌的表面肌电信号进行测量,探究电竞椅靠背与座面角度、电竞椅的使用时间、电竞椅座面的座高以及电竞椅有无扶手四个因素对电竞椅舒适性的影响机制,并结合实验结果对电竞椅设计提出了相关建议。

This paper takes the comfort of e-sports chair as the research object.In order to achieve the effect of alleviating fatigue for sedentary people,the comfort of e-sports chair is particularly important.This paper takes this as the research purpose to analyze and study the comfort of e-sports chair through the surface EMG signal produced by users,and applies the doubleconducive EMG measuring instrument to analyze and study the surface EMG signal data of e-sports chair users.By measuring the surface EMG signals of shoulder trapezius muscle,lumbar spine erector muscle,arm deltoid muscle,triceps brachii muscle,leg gastrocnemius muscle and lateral femoral muscle,this paper explores the influence mechanism of four factors on the comfort of the e-sports chair,namely the angle between the back and seat surface of the e-sports chair,the operating time of the e-sports chair,the seat height,and whether the e-sports chair has an armrest,and puts forward relevant suggestions for the e-sports chair design pursuant to the experimental results.
