摘要:  增强现实(AR)技术作为沟通现实与虚拟场景的桥梁,能够激发使用者的想象力、 空间感和创造力。现有 AR 儿童绘本在虚实结合方面不足、游戏形式和互动种类单一,缺少寓 教于乐的AR儿童绘本游戏作为内容。首先试用和研究了59款移动AR游戏并分类。使用Delphi 法选择了一些合适的游戏类型,并将其迁移到儿童绘本上。再让 6~12 岁儿童(n=6)试玩并进行 观察和访谈。同时,组织家长/老师(n=7)与开发者(n=5)形成焦点小组并针对绘本和应用进行讨 论。最终,提取了开发者(developer)、家长/老师(parents/teachers)和孩子(children)对于 AR 儿童 绘本不同的需求和对应指标,收获了对应 3 个维度的框架 DPC (developer, parents/teachers, children),且每个维度被细分。使用 DPC 框架对 AR 儿童绘本游戏进行了改进。

Abstract: Augmented reality (AR) technology, as a bridge between reality and virtual scene, can stimulate users’ imagination, sense of space and creativity. In view of the problems with the existing AR children’s picture books such as inadequate integration of virtual and reality, and homogeneity in the form of games and type of interaction, this study intends to create AR children’s picture book games capable of teaching through lively activities. Firstly, 59 mobile augmented reality applications were studied and classified. The method of Delphi was used to select some suitable game types which were then transferred to children’s picture books. Next, children aged 6 to 12 (n=6) were asked to try out our applications. At the same time, we observed what they did and interviewed them. A focus group made up of parents/teachers (n=7) and our developers (n=5) discussed the picture books and applications. Finally, the needs and corresponding indicators for AR children’s picture books were extracted from developers, parents/teachers and children. The framework DPC (developer, parents/teachers, children) on the three dimensions was obtained, each of which was further segmented. We adopted the framework DPC to improve our AR children’s picture book games.
