情境感知是移动和普适计算研究中一个重要的组成部分。现有研究大多从技术的角度进行情境感知系统的设计和实现。由于缺少对人的情境感知机制的认识，导致系统的情境感知行为和人的期望之间存在着很大的差距。在活动理论和人的情境感知理论的基础上，提出了基于活动的情境感知模型，用于描述特定活动中人的情境感知过程；并在该模型的基础上，提出了基于活动的情境感知系统交互设计方法。通过基于活动的情境感知购物助手的交互设计过程，验证了基于活动的情境感知模型在情境感知系统交互设计中的应用。

Context awareness is an important part of mobile and ubiquitous computing research field. Most existing studies con-centrate on the technical implementation of context awareness system. Due to the lack of understanding on human being’s awareness mechanism in a special context, there is a considerable gap between systems context awareness actions and human expectations to context awareness systems. Activity-based Context-Aware Model(ACAM)is built on the basis of activity theory and human situational awareness theories. ACAM describes human context-aware process enclosed with a specific activity, which can get more accurate understanding on human context awareness mechanism and lead the development of context-aware technology. The case study is conducted under the background of supermarket. The context awareness process of shopping activity and activity-based context awareness shopping assistant verifies the ACAM preliminary.
