普及计算及其应用模型

1.普及计算的基本概念 1.什么是普及计算? 我们当前所处的时代是计算机技术仍然复杂到让大部分人们难以学习的地步的时代。虽然目前计算机已经进入了许多人的家庭,但是真正能够发挥计算机全部能力的用户是很少的。计算机业界有许多的技术和专有名词,而且它们还随着时间的流逝不断发展变化。再者,过去所有的传统思路都是以计算机为中心,当计算机系统发生变化时,人们的思想也必须

Ubiquitous Computing and its Application Models

Ubiquitous computing intends to embed the entire computer system into people's daily life. It does not enforce users to have sophisticated knowledge about computers. Instead, the ubiquitous computing system provides a highly adaptive application environment by coordination of individual computing equipment. After a discussion on basic concepts of ubiquitous computing as well as basic man-machine interactions,this paper proposes some basic ubiquitous computing models including the user-centric computing model and the service-centric computing model. Extensive discussion on advantages and disadvantages of these models are also given.
