Scatter plots of presence and realism scores against VIMS scores (5th FMS and total SSQ scores). Different markers indicate data of different experimental groups. Circle: AV group; Triangle: no-AV group; Square: audio-only group; Diamond: vibration-only group. Open markers indicate female data. There are no significant linear correlations between the variables. FMS: Fast Motion Sickness scale; SSQ: Simulator Sickness Questionnaire; AV: Audio-vibration.
