普适计算

Pervasive/Ubiquitous Computing

计算技术的发展需要与之适应的计算模式 .计算技术在桌面计算模式下经历的 2 0年的飞速发展正蕴育着一种革新性的计算模式———普适计算 .普适计算是信息空间与物理空间的融合 ,在这个融合的空间中人们可以随时随地和透明地获得数字化的服务 ;计算机本身将从人们的视线中消失 ,人们注意力的中心可以回归到要完成的任务本身 .普适计算将从根本上改变人们对什么是计算的思考 ,也改变我们整个生活和工作的方式 .该文综述了普适计算研究的现状和发展趋势 ,并讨论了普适计算的两个关键研究内容———觉察上下文的计算和普适计算系统软件 。

To promote the development of computer technology it is essential to adopt a homologous computing paradigm. Now it is an urgent need to explore the new computing paradigm homologous with the current development trend of computer technology which is characterized by the more and more close integration with communication and digital media technology and embedded to the living space. That is the ubiquitous or pervasive computing. The main idea of pervasive computing is to embed computer into the living environment or tool of human, so as to make the computer invisible from users’ sight and the users can focus on their task itself, instead of the computer. Pervasive computing embodying the integration of computer, communication and digital media technology makes it possible to integrate the physical world we are living in and the virtual world in the information space together as the whole. That, as the result, will makes a profound influence on our thinking on information and our working and lives style as well. This paper surveys the development of pervasive computing including the current stage, research content and development trend. Authors’ preliminarily research results are also introduced.
