手勢互動內容創作系統之開發與評估

Development and Evaluation of Gesture-Based Interactive Content Authoring System

本研究以人機互動GOMS理論為基礎，結合手勢互動內容創作的理念，以OpenNI與Unity3D為開發工具，發展出一套手勢互動內容創作系統。本系統透過空間座標與九宮格辨識，整合手勢動作API與互動設計表，將內容以互動電子書的方式呈現，使用者在互動設計表中以拖曳方式，組合故事內容與相對應的手勢動作，達成手勢互動內容創作之目的。本研究先請專家進行系統原型評估，並以體感互動經驗、系統可用性及使用者互動滿意度三個量表進行實證資料蒐集與分析，結果顯示：本系統擁有良好的使用性；使用者覺得本系統手勢動作直覺易懂；互動設計表讓互動方式更多元且有趣。

In this study, we have developed a gesture-based interactive content authoring system which integrated gesture-based motions and story contents into an interactive design table and presented the content as an e-book. Using an interactive design table, users can drag and drop their design idea according to the story contents and interesting ways. After that, we invited experts to evaluate our system by using Questionnaire for User Interaction Satisfaction (QUIS), System Usability Scale (SUS), and the scale of Motion-sensing Interactive Experience as data collection tools. Data analysis results show that our system has good usability; users consider that using gestures is intuitive and easy to understand; the interactive design table can make the interaction more interesting.
