Stress and mental fatigue are in existence constantly in daily life, and decrease our productivity while performing our daily routines. The purpose of this study was to analyze the states of stress and mental fatigue using data fusion while e-sport activity. In the study, ten volunteers performed e-sport duty which required both physical and mental effort and skills for 2 min. Volunteers’ electroencephalogram (EEG), galvanic skin response (GSR), heart rate variability (HRV), and eye tracking data were obtained before and during game and then were analyzed. In addition, the effects of e-sports were evaluated with visual analogue scale and d2 attention tests. The d2 tests are performed after the game, and the game has a positive effect on attention and concentration. EEG from the frontal region indicates that the game is partly caused by stress and mental fatigue. HRV analysis showed that the sympathetic and vagal activities created by e-sports on people are different. By evaluating HRV and GSR together, it was seen that the emotional processes of the participants were stressed in some and excited in others. Data fusion can serve a variety of purposes such as determining the effect of e-sports activity on the person and the appropriate game type.

基于数据融合的电子竞技运动员心理疲劳和压力评估

压力和精神疲劳在日常生活中不断存在，在执行日常工作时会降低我们的生产力。本研究的目的是在电子竞技活动中使用数据融合来分析压力和精神疲劳的状态。在这项研究中，10 名志愿者执行电子竞技任务，这需要 2 分钟的体力和脑力和技能。志愿者的脑电图 (EEG)、皮肤电反应 (GSR)、心率变异性 (HRV) 和眼动追踪数据在比赛前和比赛期间获得，然后进行分析。此外，还通过视觉模拟量表和 d2 注意力测试来评估电子竞技的效果。d2测试在比赛结束后进行，比赛对注意力和注意力有积极的影响。额叶区域的脑电图表明，游戏部分是由压力和精神疲劳引起的。HRV分析表明，电子竞技对人产生的交感神经和迷走神经活动是不同的。通过将 HRV 和 GSR 一起评估，可以看出参与者的情绪过程在某些方面受到压力，而在另一些方面则很兴奋。数据融合可以用于多种目的，例如确定电子竞技活动对个人的影响和适当的游戏类型。
