近年來，智慧型互動電視的應用是不少數位生活空間研究的焦點之一。我們認為，好的互動式數位電視系統必須有生動靈活的使用介面與使用者互動。在本研究中，我們提出以智慧型3D動畫角色為介面之互動數位電視系統，希望可以藉由智慧型3D動畫角色在介面上的呈現，加強使用者於互動數位電視系統的使用經驗。在我們過去所開發的互動數位電視系統SITV上，有許多不同的互動情境可納入智慧型3D動畫角色設計的考量。我們提議讓智慧型3D動畫角色在肢體動作表現上具有行動力與表達力的概念，使得動畫角色在互動數位電視系統上，能夠依據不同的情境與角色本身之狀態，選擇適當的動作在螢幕上移動並且能呈現適當的情緒，讓互動數位電視系統之服務更加友善。本研究以JAVA開發動畫系統，並設計實驗驗證不同介面對使用者的影響，結果顯示，使用者認為智慧型3D動畫角色介面是最有善的。 / In recent years, intelligent interactive digital TV is one of the most important applications in the research of digital living space. We think a good interactive TV system must have a vivid user interface to interact with users. In this research, we propose to incorporate intelligent 3D character into the interface design for interactive digital TV system, to enhance the user experience of the interactive digital TV system. In the smart interactive digital TV system we developed before, call SITV, many interactive scenarios can be considered in the design of intelligent 3D character. We propose to develop our intelligent 3D character with the concepts of mobility and expressiveness on body motion such that appropriate emotions can be presented through motions depending on the scenario and character configuration. For example, an intelligent 3D character can act like a housekeeper living in the TV monitor. He can take different actions for different scenarios to make the service friendlier. We have developed our animation system in JAVA and designed experiments to evaluate different types of user interface design on different scenarios. The experimental results show that an interface with an intelligent 3D character will be friendlier than the others.

人或擬人生物佔眾多動畫主題的大部份，而要使人物動畫看起來栩栩如生，除了適當的臉部表情外，能夠傳達人物情感的肢體動作更是不可或缺。本研究的目標在於以電腦程序產生帶有情緒成份之人物肢體動畫。此目標包含兩個子目標：第一、設計以人類肢體動作為目標的參數化程序，以提高程序之重用性及泛用性，降低製作程序式動畫的成本，並製作出以關鍵格為基礎之人物動畫；第二、將我們製作的動畫加入風格，並以心理學實驗驗證人物的動作和情緒的關聯。我們的實驗先將風格套用於走路動作上，來證明我們操弄風格的方法符合大眾的認知。再者，我們針對走路動作嘗試以實驗找出風格和情緒的對映，再將此對映關係套用到具特定情緒意涵的動作上，以證明這些對映有助於情緒的表達。 / Human or human-like creatures are the main subjects of computer animations. In addition to facial expression, body gestures and motions are also indispensi-ble components for realistic character animation. The goal of this research is to create emotional character animation with computer procedures. This goal may contain two subgoals: first, we aim to design parameterizable animation proce-dures for human body motions in order to reduce the cost of producing key-frame based character animations with improved generality and reusability; second, we incorporate style into procedural animation and validate the relation model between emotion and motion with psychology experiments. We first ap-plied different styles into the walking motion and conducted experiments to see if the participants can agree with the way that we manipulate the style parame-ters. Furthermore, for the walking motion, we conduct experiments to find the mapping from the emotion parameters to the style parameters. Then we applied this mapping to emotion-specific motions to see if the animations perceived by the users can be further enhanced.
