本研究提出一套基於虛擬實境（VR）的懷舊治療（RT）系統，旨在提升情緒健康與記憶喚起效果。該系統以 Unity 開發，重建台南奇美博物館的高擬真 3D 模型，並整合個人照片、懷舊音樂與語音引導等互動元素，以喚起使用者的自傳式記憶。實驗共招募 10 位年齡介於 23 至 25 歲之參與者，並蒐集其眼動、頭部動作、心率變異（HRV）與互動行為等數據進行行為分析。系統的使用性與沉浸感透過 SUS、NASA-TLX 與 Presence Questionnaire 進行評估。實驗結果顯示，虛擬環境中的懷舊相關物件能有效吸引部分參與者的注意力，從多位使用者的注視比例提升中可見一斑。生理數據亦顯示，在老歌事件期間，多數參與者的心率下降且 HRV 上升，反映出更為放鬆與穩定的生理狀態。本系統在使用性與沉浸感方面皆獲得高度評價，參與者普遍感受到強烈的臨場感與易用性。上述結果支持 VR 應用於懷舊治療的有效性與潛力，有望成為未來心理健康介入中兼具個人化、沉浸式與可近性的輔助工具。;This study presents a Virtual Reality (VR)-based Reminiscence Therapy (RT) system designed to enhance emotional well-being and memory recall. Developed using Unity, the system reconstructs a realistic 3D model of the Chimei Museum and integrates interactive elements such as personal photos, old music, and voice guidance to evoke autobiographical memories. The experiment recruited 10 participants aged 23 to 25, and collected data on eye movement, head movement, heart rate variability (HRV), and user interactions for behavioral analysis. Usability and immersion were assessed using the SUS, NASA-TLX, and Presence Questionnaire. Experimental results showed that reminiscence-related objects in the virtual environment effectively attracted participants′ attention, as evidenced by higher gaze proportions among several users. Physiological data revealed that during the old song event, most participants exhibited decreased heart rate and increased HRV, suggesting a more relaxed and stable physiological state. The system achieved high usability and immersion scores, with participants reporting strong presence and ease of use. These findings support the effectiveness and potential of VR-based reminiscence therapy for emotional regulation and stress reduction, offering a personalized, immersive, and accessible approach for future mental health interventions.
