A repeated measures, full factorial experiment was run on the UTIAS flight research simulator with nine subjects to study the effect of four factors on the detection of phase difference between motion and visual cues. Motion gain, amplitude, frequency and visual scene complexity were the four factors. Two levels were tested for each factor, resulting in sixteen sessions for each subject. A Kennedy SSQ was administered to the subjects following each session. Simulator motion was limited to sinusoidal pitch. Results from this study indicate a mean phase difference perception threshold of 56.3° with a standard deviation of 5.67°. Motion gain, amplitude, motion gain × frequency and motion gain × frequency × visual complexity were found to have a significant effect (95% confidence) on the perception threshold. Simulator sickness was mild across all the subjects with a total severity sickness score mean value of 1.91. One significant effect on simulator sickness was found: amplitude × frequency × visual complexity.
