Development and Experiment of the Interactive System for Immersive Movie Watching Experience

隨著數位資訊科技蓬勃發展，帶來許多閱聽的變革與創新。以電影來說，單一的視覺和聽覺效果已經無法滿足觀眾，觀看可能性也越趨多樣化，同時，在設備的進步下，選擇在家裡看電影的人也不在少數，換句話說，在家裡使用小螢幕看電影雖不至於完全取代電影院觀影，卻已逐漸成為電影觀眾的主流觀影方式。另外，媒體的創新和載具的多樣化早已顛覆大眾閱聽習慣，因此我們思考，電影本身是否能結合「互動」特質，使得在家觀影也能享有如電影院般的沉浸體驗。 本研究以每個家庭幾乎會有的配備—桌上型電腦加上小型視訊攝影機，利用電腦視覺技術偵測觀者位置，觀者藉著身體的移動去控制影片觀看視角，並配合適切的敘事內容，誘發觀者想「看」的好奇心。我們希望讓影像的敘事性融合數位空間的瀏覽，更貼近於直覺的本能去決定故事的片段，使觀者全身感官沉浸於敘事的世界，提升使用者對故事的認同。 本系統招募十位使用者進行體驗，透過問卷、訪談和影像側錄以檢測研究目標的成效。實驗結果顯示大部分使用者皆認同此系統的設計，且認為是有趣的，有助益於進入沉浸狀態，但在許多細節上仍有改進的空間，我們相信本研究提供了數位互動敘事上一個新的方向，開啟導演與觀眾之間不同的對話方式。本文最後將建議與未來方向彙整做為後續研究參考。With the digital contents technology emerging, more and more innovations about reading and listening are happening. In the film, simple visual and auditory effects have not been able to satisfy the audience. Besides, people go to see a movie not only in the theater but also at home, so we start to thinking of whether the movie could incorporate interactivity such that watching movie at home could be the same as or even better than in theater. Computer with a webcam is the main equipment in our system. We use computer vision technology to detect the position of the viewer, and the viewer moves his body to control the viewing angle of the video. We want to combine narrative and digital space to allow a viewer to determine the plot of the story in an intuitive way, such that this interactive mode can enhance the viewer’s immersive experience and allow the viewer enjoying the story. The system has been implemented, and we recruited ten users to participate in the experiment. Through questionnaires, interviews, and recorded video analysis, we get feedbacks which help us understand the advantages and disadvantages of our system. The results show that most users agreed with the design of this system and considered it interesting except for some implementation details. We believe that our study offers a new way for digital interactive narrative, which opens a different way of communication between director and audience. At the end, we propose some suggestions for future improvement
