摘要

隨著資訊科技的快速發展，以資訊科技來輔助學習的數位學習已成為教育學習中重要的一環。以往數位學習系統因為技術的限制，較缺少讓學童進行實體接觸和操作，以及幫助幼童感覺統合發展的機會。本論文想探討運用擴增實境能結合虛擬與真實環境的特性，讓學童實體操作教育器材時，能否同步獲得虛擬資訊輔助的可能性，藉以探究擴增實境技術運用在數位學習系統的可能性。
本論文運用擴增實境技術來設計一套七巧板輔助學習系統，在七巧板貼上基準標記，系統利用擴增實境技術對基準標記的即時偵測能力，偵測學生擺放七巧板的位置以解析學童操作七巧板時的狀況。此系統並根據學童操作狀況以及所花時間多寡，提供四種不同層次的資訊輔助提示，來逐步提升對學童排列七巧板的輔助強度，讓各種程度的學童在操作七巧板時，能即時獲得最適切的協助。本研究讓20位幼稚園學童實際使用此擴增實境輔助七巧板學習系統來排列出指定的七巧板圖形，紀錄觀察的結果顯示，學童均能在本輔助學習系統的輔助下拼接完成指定的七巧板圖形，系統以擴增實境技術來偵測七巧板也有很好的即時偵測能力及準確度。學童也對此擴增實境輔助七巧板學習系統表達出高度的滿意度。

With the rapid development of information technology, e-learning that applies information technology in education has become an important role in the education. In the past, e-learning provided fewer opportunities for children to contact and operate physical objects and to develop sensory integration. This study aims to investigate whether augmented reality that combines virtual and real environments would synchronously provide virtual information support when children are operating the educational physical equipment, and to further explore the possibility of applying augmented reality in e-learning.
This study designed an augmented reality assisted learning system for Tangram puzzle. With the reference markers on the puzzles, the system was able to detect the position where a student locates Tangram puzzles and to detect the student puzzle status. Based on the student puzzle status and spent time, this system provides four information supplemental assistances which gradually help students in different levels; therefore students in various levels were able to receive appropriate assistance while operating the Tangram puzzle.
This study also asked 20 kindergarten students to use the augmented reality assisted learning system to arrange specified graphics by Tangram puzzles. The observation results show that all children were able to complete the assigned Tangram puzzle graphics under the assistance from the system. The results also reveal that the system can detect mostly the Tangram puzzle status. In addition, the children expressed a high degree of satisfaction at this augmented reality assisted learning system.
