上下文感知计算及系统框架综述

当人们在与其他人或周围的环境交互时,常常会无意识地利用到诸如手势、眼神、情境、环境状况等上下文信息 .与之相反,计算机系统却很少能有效地利用这些信息 .但自Mark Weiser提出普适计算以来,如何有效利用上下文信息开始得到充分重视并发展成为一种新的计算模式--上下文感知计算 .通过对近10年来上下文感知计算尤其是系统框架的发展进行综述和分析,提出了一个新的上下文感知计算系统框架概念模型,同时对该概念模型所涉及的关键技术问题进行了深入探讨,这可为感知计算的进一步研究提供指导 .

A Survey of Context-Aware Computing and Its System Infrastructure

Contexts like gestures, emotions, situations are very useful when a person interacts with other persons or nearby situation. On the contrary, computer can not use contexts efficiently. But computing-aware computing now is becoming more and more important since pervasive computing was put forward by Mark Weiser in 1991. The research of context-aware computing, especially its system infrastructure, is surveyed. The main contribution of this paper is an innovative system infrastructure conceptual model and the key problems of the model are discussed in detail.
