普适计算（Ubiquitous computing（ubicomp）、pervasive computing），又称普存计算、普及计算、遍布式计算，是一个强调和环境融为一体的计算概念，而计算机本身则从人们的视线里消失。在普适计算的模式下，人们能够在任何时间、任何地点、以任何方式进行信息的获取与处理。

普适计算是一个涉及研究范围很广的课题，包括分布式计算、移动计算、人机交互、人工智能、嵌入式系统、感知网络以及信息融合等多方面技术的融合。普适计算在教育中的应用项目：（1）清华大学smart class项目、（2）**淡江大学的硬件SCORM项目、（3）MIT的Oxygen项目。

Ubiquitous computing (or "ubicomp") is a concept in software engineering and computer science where computing is made to appear anytime and everywhere. In contrast to desktop computing, ubiquitous computing can occur using any device, in any location, and in any format. A user interacts with the computer, which can exist in many different forms, including laptop computers, tablets and terminals in everyday objects such as a fridge or a pair of glasses. The underlying technologies to support ubiquitous computing include Internet, advanced middleware, operating system, mobile code, sensors, microprocessors, new I/O and user interfaces, networks, mobile protocols, location and positioning and new materials.
