摘要:	傳統的教學都是在教室內由教師單方面的傳授知識，但知識是學習者與環境互動的產物，學生應該要在真實的環境中學習，習得的知識才有意義。然而，在一般的課堂上很難創造一個真實的知識運用環境，有許多限制。擴增實境技術的進步，利用擴增實境有可能在教室內使用混合實境建構一個模擬真實的情境，呈現豐富的場景。若學生要能進入混合實境場景跟環境做互動，則需要建立的環境非常大、技術比較複雜、成本也較高，對於推廣到一般學校裡面或家庭中有實質上的困難，因此，必須找一個扮演學生代理人的角色，代替學生進入混合實境的場景中與場景做互動。玩具型和教育用機器人逐漸成熟，價格也慢慢降到可負擔範圍，因此本論文使用機器人做為學生的代理人，進入混合實境的場景來做互動。本論文設計了一個機器人的控制程式，可以在混合實境中和環境及學習者做互動，機器人會讀入場景地圖及本身的座標，因此知道自己在場景中的位置，可自行做事件觸發的判斷，並可以做邊界及例外的判斷與處理。利用機器人內建的sensor來設計與學習者互動的方式，並在電腦上擴增機器人語音的辨識與輸出能力。可以讓學習者用各種不同的方式和機器人互動，讓學生感覺在真實的環境中學習。本系統的實驗對象為36位大崙國中二年級的學生，分別使用加入機器人的混合實境學習系統及控制虛擬機器人圖示來代替實體機器人的學習系統。實驗結果顯示，機器人的加入讓混合實境學習系統更有真實感與刺激感。和機器人互動也讓學習者覺得很有趣，透過和機器人互動的過程，提昇了混合實境學習系統的臨場感，可以讓學生融入在設計好的情境內，也會更投入在學習活動當中，進而提昇其學習的動機。 The traditional instruction is carried out by the teacher in the class with single side. However, knowledge is the production of the interaction between learners and surroundings. It’s meaningful for students to learn in the physical surroundings. Actually, it’s hard to build a knowledge-manipulating surrounding which contains many limitations. With the advance of augmented reality techniques, building a mixed reality of rich scenes with augmented reality has come true in the class. To interact with the surroundings in the mixed reality is expensive and hard for students; it’s hard to promote the ideas to schools or family. Therefore, we had to find a student deputy as a representative to immerse in the mixed reality and to interact with the surroundings. Toy robots and robots for education become popular and the prices are acceptable within the budget, so we used robots as the student deputy to enter the mixed reality to interact with the surroundings. In this research, we design a program, which can control robot in a mixed reality surroundings. Robot can interact with surroundings and learners. The program will read the map and robot’s coordinate in the scene. So robot knows where it is. Robot can detect the occurrence of events and deal with the boundary and exceptions by itself. We designed the interaction modes with learners by using the sensors which the robot built-in. We also expanded the robot’s ability in voice recognition and voice output. Learners can use multiple way to interact with the robot. Students will feel like learning in the physical surroundings. In this research, the subjects are 36 second grade junior high school students. They used the mixed reality learning system with robot and the learning system which use robot icon substitute the physical robot. The experiment result shows that mixed reality learning system with robot, students feel more authentic and exciting. Students feel more interesting, engaging, and increasing the presence and learning motivation though interacting with robot.
