Abstract:	隨著虛擬實境蓬勃發展，VR的市場亦日漸龐大，但是其所帶來的暈眩問題卻始終存在，讓無數使用者苦不堪言，其中又以控制器為主之靜態虛擬實境系統最為嚴重。雖然目前學界、業界已發明出了許多減緩暈眩的機制，不過相對都有其缺點與限制，而其中最重要的是這些機制似乎是普世通用的，且大多限制在單一旋轉或平移情境中使用。然而，每個人的動暈敏感程度不盡相同，倘若都採用一樣的機制類型，可能會讓敏感的人無法真正受惠、達到舒適最大化，不敏感的人則要犧牲體驗、換取不必要的減暈效果。因此，本研究針對個人動暈敏感性、客製化的減暈機制類型、旋轉和平移並行之情境提出一個整合性的研究，希望探討在綜合情境下，是否能夠依照人們不同的動暈敏感程度，給定客製化的機制以降低其不適感，讓每位使用者都能在VR中擁有最舒適的狀態，以最少的暈眩感，獲得最好的體驗。本研究總共分成兩階段的實驗，在第一階段的初步研究中，透過旋轉和平移情境各五種速度，分別找出一個能區分不同動暈敏感特性的臨界速度值，並且依照此結果設計一套前置測試系統，以用來量測移動錯覺的動暈敏感程度。在第二階段的正式實驗中，我們藉由此系統作為預試，將受試者依照其旋轉、平移敏感的高和低，分成四種動暈敏感組別，並導入學者發明的旋轉、平移減暈機制，分別給定開和關所組成的四種減暈模式，以了解各組別在各模式下的反應。從實驗結果的趨勢中，我們觀察到特定的動暈敏感組別、在特定的減暈模式下，確實有助於減輕暈眩，且每個人對於旋轉錯覺和平移錯覺在動暈敏感性上亦存在差異，證實了客製化減暈的可行性與必要性。透過此研究，我們期望能為日後的虛擬實境暈眩領域，提供新的發展方向和對客製化研究的相關建議與參考。
