基于分布式认知的儿童增强现实编程环境的研究

Programming is an effective way to help children to learn computational thinking skill, which is very important for them at the early age. Based on the theory of distributed cognition, this project researches child-friendly tangible programming techniques, cooperative learning and augmented reality (AR) technology. We strive to provide children with an easy-to-learn and easy-to-use programming environment, to help them understand basic programming concepts and develop their computational thinking abilities. The project focuses on the following aspects: research distributed cognition theory and summarize cooperative learning principles which offer a guidance in developing the software environment (including cooperative programming) for children; studying distributed cognition theory based physical interaction and augmented reality technologies and constructing the physical interaction model; developing tangible augmented reality programming system and providing easy-to-learn user interfaces (programming environment); researching on physiological parameters based children experiment evaluation methodology, making evaluations based on programming system prototype in order to assess its validity; the children-oriented physical AR programming prototype system will fill in the gap in the domestic market(field) of children augmented reality programming software and offer a much more efficient mode for novice to learn programming. Meanwhile, the project is also meaningful and valuable to promote the research and application of tangible interaction techniques for children.
