VJ表演隱藏著一種矛盾性。VJ表演之觀眾特徵，較常表現出非主流的品味，傾向於追求與眾不同的體驗，與對於自主權的掌握展現較高的積極性。然而享受音樂表演意味著某種程度的沈浸與忘我，在觀賞表演時需暫時捨棄自身的自主權與主體性方有可能真正享受其中，這之間便產生了控制與被控制的矛盾。當互動科技的元素介入到VJ表演時，這種矛盾性就會更加明顯，甚至被揭露與強調。互動科技的加入旨在過程中使人們能夠參與，讓人們擁有做決定或影響表演的權力。故互動的VJ表演具有控制權矛盾之特徵，而這樣的矛盾性應當被表演設計者所發現並探索。本研究希望透過理論爬梳與作品實踐，探索互動加入在VJ表演時如何提高觀眾的參與感。於是如何盡量減少互動所造成的干擾性以完成一場互動表演，便成為本研究關心的一項重點。 　　在內容主題上，台灣民間信仰是關於控制與被控制一個很好的轉喻。故此計畫將設計一個以台灣民間信仰為主題的互動VJ表演，並利用台灣民間信仰來反映觀眾主體性矛盾與控制權矛盾的不同面相。

近年來越來越多虛實整合技術不斷地湧出，像是電影阿凡達或虛實互動型態的表演。這樣的表演會根據事先預錄好的虛擬角色進行演出，但要成功地演出需要演員們不斷的練習。另外,許多電影利用攝影機捕捉人體姿態來與虛擬角色互動，但此方法受限於燈光環境以及障礙物。 此篇論文運用穿戴式裝置與新一代無線網路藍芽4.0,提出即時追蹤技術套用於這類表演,可使得演出更加豐富並且能即興創作。然而，目前受限於穿戴式平台上的藍芽訊號強度更新頻率每秒只有5至10次且傳輸容量有限，所以本篇論文結合體態感測裝置輔助無線網路藍芽4.0,提升對穿戴者的即時追蹤能力。實驗結果與真實位置只有0.3至0.5秒的延遲時間,並在校內進行兩場互動式展演作驗證成果。未來期許可以將此技術運用於多人展演場，讓更多使用者可以互動體驗。 / Recently, more and more interactive performance technologies appear such as Avatar or virtual-character integrated art perform. Such performs are based on pre-made animations and physics simulations. However, this kind of shows need a lot of practice, and it is impossible that audience or performers play with or interact with the virtual characters. In addition, many moviemakers use high quality cameras to distinguish body postures. Although cameras can record anything with high precision, it is constrained on the light and obstacles of the environments. If we, somehow, can capture the motion of the performers in real time, then we are able to interact with virtual characters and make improvisation possible. This thesis aims to use the wearable sensors and the Received Signal Strength Indication (RSSI) of BLE to track in real-time. However, the update rate of RSSI is limited to 5~10 per second. This thesis proposed a tracking technique which combines with wearable motion sensors to assist BLE localization. The tracking lag can be reduced to only 0.3~0.5 seconds, and also real performance was experimented in the campus. In the future, we hope to use this technique on interactive performance with many people in different places.
