摘要
虛擬樂器是利用沈浸式裝置在三維虛擬環境中演奏的數位樂器，和非沈浸式的數位音樂介面不同，多感官與類假肢式的動作捕捉介面取代了抽象的操作介面；更與傳統樂器不同，盡可能的隔絕了除了樂器及虛擬環境外的其他視、聽覺。研究將探討當樂器成為沈浸式體驗時的臨場感，以及更深入探討節拍校準是否會影響臨場感。
表演者穿戴頭戴式顯示裝置及控制器演奏虛擬樂器，其中在實驗組與對照組執行指派的演奏任務時，以虛擬樂器的節拍校準介入實驗組，對照組則不介入，完成實驗設計的任務後並填寫沈浸傾向與臨場感量表，測試在不同情況下演奏虛擬樂器產生的臨場感是否有區別。
本研究結果顯示，有無節拍校準對於使用者的臨場感有顯著相關，確實可以輔助使用者更容易掌握虛擬樂器，並且省去控制節奏所需的專注力，進而關注更多其他音樂特性。節拍校準的介入能左右使用者的臨場感，並且提升其真實性、操作的可行性與觸覺回饋，整體來說具關鍵性的影響力。
本研究評量了獨奏者對於新型態樂器功能的使用心得，在節拍校準使用者體驗的研究基礎上，更甚可以量測節拍校準對於多人合奏的體驗。以虛擬樂器的臨場感研究為基礎，可以深入研究臨場感對於音樂創意、情緒和樂器的學習曲線有沒有關聯，以此為界便可使傳統樂器與虛擬樂器間功能性的界線更明朗。

Abstract
Virtual reality musical instruments are digital musical instruments that use immersive devices to play in a three-dimensional virtual environment. Different from non-immersive Musical Instrument Digital Interface, the prosthetic-like interfaces of virtual reality musical instruments are multi-sensory and motion capture , instead of abstract control interfaces. In addition, when playing virtual reality musical instruments, users can immerse themselves as much as possible in the experience of virtual environments and musical instruments without being disturbed by the sights and sounds in the real world. This research will examine the presence of playing an instrument through an immersive installation, as well as delve deeper into whether quantization of rhythm will affect the presence.
The users will wear a head-mounted display device and a controller to play a virtual reality musical instrument. When the experimental group and the control group perform the assigned performance tasks, the experimental group will be involved by instruments' quantization of rhythm, on the contrary, the control group will not be involved. After completing the tasks, all the users will be required to fill out Immersion tendencies and Presence Scale, which is the material to analyze whether there is a difference in presence in different situations.
The results of this study show that the rhythm quantization involved or not is significantly related to the user’s sense of presence. It can indeed help the users to control the Virtual reality musical instruments more easily. Besides, with the assistance of rhythm quantization, users can reduce the concentration needed to control the beat and pay more attention on other musical elements. To sum up, the intervention of rhythm quantization not only have a great influence on the user’s sense of presence, but also can improve the experience of realism, possibility to act and haptic feedback. In the other word, rhythm quantization was a key impact as a whole.
This study evaluates the instrumental soloists ' experience when using the functions of the new type of instrument. Based on the research on user’s experience of rhythm quantization, this experiment can even evaluate the experience of rhythm quantization for ensemble in the future. Founded on the presence of virtual reality musical instruments, it is possible to deeply study whether presence is related to musical creativity, emotion and the learning curve of musical instruments. Taking this as a boundary can make the functional between traditional instruments and virtual instruments clearer.
