Effects of Simulator Sickness and Emotional Responses When Inter-pupillary Distance Misalignment Occurs
The aim of this study was to empirically investigate the effects of inter-pupillary distance (IPD) misalignment on simulator sickness and emotional responses. Twenty participants were recruited from an advertisement. The experiment has five conditions to change the differences between IPD and head-mounted display (HMD) optical systems. As results, simulator sickness significantly decreased by aligning the HMD optical systems based on the IPD. Extending previous studies, the results demonstrated the different patterns in emotional arousal and valence. For future study, we are conducting a second experiment using eye-tracker to investigate whether anomalies occur in pupil movements. This study might help to inform the important of IPD misalignment problem by measuring visual discomfort quantitatively.
