Effect of controlled consciousness on sense of presence and visually induced motion sickness while viewing stereoscopic movies

Abstract

In our previous study, we found it is possible to have an effect of change in the condition of consciousness (allocation of consciousness) on visually evoked postural response (VEPRs) Then, in this study, we verified effect of controlling consciousness on VEPRs, visually induced motion sickness (VIMS), a sense of presence while viewing 3D movies. Participants watched 3D movie consisted of several colored balls sinusoidal moving at 0.25 Hz in the depth direction for 3 min each under condition following pre-instruction. The detail of the pre-instruction were “sway body in a parallel/opposite direction”. The position of the body sway center of pressure was continuously recorded. As subjective evaluation, participants completed a simulator sickness questionnaire and reported three feelings (the sense of presence, motion and interactive) by using a visual analog scale. The results clearly showed that (1) The influence of pre-instruction appeared much stronger than that of VEPRs, and (2) The relationship between change in body sway and degree of VIMS or the feeling of presence do not always match under the situation included multi factors related to sense information or the condition of consciousness.
