Influence of Fixation Point Movement on Visually Induced Motion Sickness Suppression Effect

Abstract

Previous studies reported that rendering the fixation point is effective for suppressing visually induced motion sickness (VIMS). This study investigates why the fixation point has a VIMS suppression effect. Gazing-specific-place and gazing-specific-object are two properties of static-fixation points. To clarify which property is responsible for the VIMS suppression effect of fixation points, we employ a moving-fixation point and employ 3D CG content experienced by participants through a head-mounted display (HMD). This study compares the following: no-fixation-point, static-fixation-point, and reciprocating-fixation-point conditions. Each condition is evaluated by a simulator sickness questionnaire (SSQ) and subjective evaluations. Both the SSQ and subjective evaluation results show the VIMS suppression effect and compare it under the reciprocating-fixation-point condition and with the no-fixation-point condition. The gazing-specific-object property might cause a VIMS suppression effect.
