中文摘要：

计算的无处不在使得计算机已成为儿童学习、娱乐的工具，而设计和开发面向儿童的互动系统的主要瓶颈在于如何设计界面隐喻，使其更易于儿童理解和使用．通过对现有界面隐喻的分析，针对儿童的认知特征提出一个基于儿童卡通读物的界面隐喻——3IBook，并从结构设计、操作设计和实效设计3个方面描述3IBook的设计特征；同时分析了基于3IBook的交互模型．最后通过一个互动游戏系统的实现来评估该隐喻在面向儿童的交互式软件中应用的合理性和有效性．

英文摘要：

An increasing number of children are becoming the users who employ computers for learning and entertainment with today＇s ubiquitous computing. The bottleneck of designing an interactive game for children is the design of suitable interface metaphors so that it can facilitate the children＇s understanding and exploration. In this paper, we argue that traditional interface metaphors built for office usage are not well fit into the perceptual and cognitive features of children, and propose a novel interface metaphor for children, named 3IBook, based on the paper cartoons. The major characteristics of the metaphor are interactivity, immersion, and imagination （3I＇s）. We describe the design features of the metaphor from the perspectives of structure, operation and pragmatics, and illustrate the interactive model built on the 3IBook. We demonstrate the rationale and effectiveness of the proposed approach by evaluating the realization of an interactive game in terms of this metaphor.
