Evaluation of the effect of visually-induced motion sickness based on pulse transmission time and heart rate

To evaluate the effects of visual stimulation on humans by using the physiological index which can be obtained from a compact and low-cost device, the maximum cross-correlation coefficient from pulse wave transmission time (PTT) to heart rate was introduced. This index was compared with the similar index based on blood pressure in place of PTT in the experiment in which 51 subjects were watching video image to induce motion sickness.
