为了评估视觉刺激对多受试者观看同一图像的生物学效应，开发了一种更紧凑、成本更低的同时测量ECG和光电容积图的设备。在这些生理参数的基础上，可以计算出脉搏波传输时间与心率之间的最大互相关系数，即正交矩阵。该指标反映了自主神经系统的活动，被认为是评价视觉刺激对人体影响的一个很好的指标。通过6名被试同时观看一段用手持相机随意摇摆拍摄的视频图像，实验结果表明，几乎所有被试的rhomax在视频图像的后半部分都有所下降，其中有强烈晕动病感觉的被试的rhomax在某一时刻观看完视频图像后都有所下降
To evaluate the biological effects of visual stimulation on multiple subjects watching a same image, a more compact and low-cost device measuring both ECG and photo-plethysmogram was developed. On the basis of these physiological parameters, the maximum cross-correlation coefficient, rhomax, from pulse wave transmission time to heart rate could be calculated. This index reflects the activity of the autonomic nervous system and is considered as a good index for evaluating the effect of visual stimulation on humans. The result of simultaneous experiment with 6 subjects watching a video image taken by an intentionally swaying handy camera has shown that rhomax of almost all subjects decreased in the latter part of the video image and that rhomax of the subjects who felt motion sickness strongly decreased after watching the video image at a time
