摘要

Stoffregen 與 Riccio (1991) 提出以個體身體姿勢不穩定的情況來探討個體是否會產生動暈效應，因此個體有無附加移動的議題為重要變項之ㄧ，本研究探究環境情境的操弄與個體自主性與否，進一步觀察身體姿勢控制並填寫虛擬情境暈眩問卷 (SSQ) 以了解個體是否有產生暈眩等不適的症狀。研究對象為20名無前庭或內耳器官失能病史，且視力正常(或矯正後)之成人為實驗參加者，要求參與實驗前40分鐘內不要進食實驗情境。透過移動室 (moving room) 裝置使個體在無附加移動及無身體擺動的情境下，覺察因移動室前後移動而產生的視覺訊息是如何影響個體的姿勢控制。資料收集以六自由度磁力追蹤儀 (Polhemus LIBERTY)與MotionMonitor軟體收集，並以相依樣本三因子變異數分析進行統計考驗。研究結果發現個體身體姿勢不穩定的情形會產生動暈效應，當個體處在附加移動的情境下亦影響身體擺動而產生動暈效應，尤其在移動室與附加移動的情形時，造成個體在姿勢的穩定度改變，而當個體長期處在姿勢不穩定便易引發個體動暈效應的發生。

Stoffregen and Riccio (1991) they consider that the individual feel the motion sickness were caused the posture instability. Therefore the imposed motion can be important topic for discussion. The study was about the environment conditions and individual imposed motion, then we used the body posture and wrote the Simulator Sickness Questionnaire, SSQ, to consider the motion sickness and any uncomfortable symptom. There had 20 participants that reported no history of recurrent dizziness, recurrent falls, or vestibular (inner ear) dysfunction and normal or corrected to normal vision and in the experiment. They couldn’t eat food in 40 minutes before the experiment. Participants percept optical information through the moving room, imposed motion and body sway restrained to effect the body control. Data on postural motion were collected using an Polhemus LIBERTY and MotionMonitor. It used Three Way ANOVA to analyze. The study results was the individual’s posture instability caused motion sickness easier and they had motion sickness in the imposed motion condition. In particular when the moving room and imposed motion were bath movement, their posture got more instability. If the posture instability were in long time, it induced the motion sickness.
