Visually-Induced Motion Sickness: Effects of Adaptation

This research was designed to empirically examine the effect of adaptation training using a simulated rotary stimulation (SRS) technique on simulation sickness and inducing graded motion sickness through the systematic distortion of the relevant characteristics of two VR devices (VE and optokinetic OKN drum). Forty participants were randomly assigned to either a control (no training with SRS) or experimental (4-day training with SRS) condition. The results indicated that the experimental group who had prior training with SRS reported lower DLQ scores (Mean=2.09) than the control group participants (Mean=4.09) following VE exposure. Similarly, the experimental group who had prior training with SRS reported lower DLQ scores (Mean=1.95) than the control group participants (Mean=3.68) following OKN exposure. With regard to SSQ scores, the experimental group who had prior training with SRS reported significantly lower SSQ scores following the day 5 SRS exposure (Mean= 11.49) than the control group (Mean=1.60). Furthermore, the experimental group who had prior training with SRS reported significantly lower SSQ scores (Mean=11.75) than the control group participants (Mean=22.71) following VE exposure.
