目的 对歧义交互中 “矛盾性” 的生成机制、 特征与设计方法进行研究。方法 以符号互动理论为基础， 构建设备信息与用户解释的人机交互模型， 对歧义交互中的 “矛盾性” 进行理论和应用分析。结论 歧义设计不同于可用性设计、 诺曼的概念模型、 模糊设计以及设计失误，“矛盾性” 作为歧义交互中设备/用户关系的极端情况， 是界定歧义交互性质和范畴的关键点。

It studies the formation mechanism，features and design concepts of "Paradoxity" in ambiguity design. Based on the theory of symbolic interaction， it established the human-machine interactive model of devices information and users interpretation，made theoretical and application analysis of "Paradoxity" in ambiguity design. The ambiguity design is different from usability， Norman concept model， fuzzy design and design fault. "Paradoxity" is a critical point to define the interactive quality and category of ambiguity as the extreme condition between devises and users in ambiguity interaction.
