最近幾年，隨著電腦科技的進步與多媒體技術的成熟，虛擬人物已經成為人機互動研究中最具熱門討論的議題之一。論文中，我們想設計一個具有目標的虛擬人物於學習系統上，虛擬人物將有目的的引導學生進行學習，並在學習中，關懷學生的需求，提供同理回饋，改善學生負面情緒和給予適當的責備和鼓勵，幫助學生克服學習的問題。 一個初步的實驗被實行，並且顯示了這樣的虛擬人物能更自然的與學生進行互動，同時增加學習易意願並且讓學生更願意去接受虛擬人物所給的意見。 With the advances in computer technology and the maturity of multimedia technology, the agent has become the hottest issue of discussion over the study of human-machine interaction in recent years. The agent exploits the social dialogue to show goal and its care for students in a learning system. The agent will purposefully guide students in the learning process, care about their needs during learning, provide empathy feedback in order to lessen their negative emotions, and offer appropriate reproach or encouragement to help them overcome the obstacles to English learning. A preliminary experiment will be done to show that this agent can interact with students more naturally and meanwhile strengthen their will to learn as well as make them more willing to accept the opinions from the agent.
