摘要: 通过采集被试在观看3D电影过程中的心电数据,结合主观打分及实验前后问卷、反应时数据来研究观看过程中视疲劳和心电指标的变化规律,找到能够反映视疲劳的心电指标并对视疲劳进行建模。实验分析了12个被试数据,从时域和频域两个方面对心电信号进行分析。分析结果发现,主观打分和心率(HR)随着观看时间持续而增大,PNN50随观看时长增加变小。对主观打分进行线性建模,得到模型R2为0.930。此外,主观问卷表明在实验后总体视疲劳,眼睛干涩,感到恶心等症状均发生显著变化(p<0.05)。

Abstract: This study investigates and models the correlation between visual fatigue and ECG data by collecting the ECG data of the participants during watching 3D movies, combining with the subjective scores, the reaction time, and the questionnaires before and after the experiment. ECG data of 12 subjects were analyzed in both time and frequency domain. The results showed that subjective score and HR increased with the duration of viewing, while PNN50 decreased. Linear model of subjective score is established, and the R² of model is 0.930. Subjective questionnaires show significant changes in overall visual fatigue, dry eyes and nausea symptoms after the experiment (p < 0.05).

Key words: stereoscopic display, visual fatigue, HRV, time and frequency domain analysis, modeling
