基于FDI的用户模型及其在上下文觉察计算中的应用

上下文觉察计算是普适计算的重要内容。当前的上下文觉察计算研究大多没有为用户提供个性化的服务。已有的个性化上下文觉察服务的用户模型，其用户偏好的设置比较简单。本文从心理学的观点出发，提出一个使用基于场依存一独立性（FDI）的用户模型来为用户提供个性化的上下文觉察服务。本文系统分析了这种用户模型对上下文觉察计算的重要性，并给出了使用基于FDI的用户模型在上下文觉察计算中的应用过程。试验表明这种模型提供的个性化服务能够提高上下文觉察计算应用的有效性。

To Construct and Use FDI-based User Profile in Context-Aware Computing

Context-aware computing is an important composition of pervasive computing.Most context-aware computing researchers get their focus on the using of context while few of them has involved with user profiles.Besides,even they used user profiles,the attribute settings in them are simple and naive.We propose a FDI based user profile to provide users with personally context aware services from psychology perspective.On the other hand,we analyze the importance of the FDI based user profile to context aware computing and give out an application process to use FDI based user profile in context aware computing.Simulating experiments are given to explain the effectiveness of improving the degree of providing personal services in context aware computing environment.
