Ubiquitous Computing

Pervasive computing is also called universal deposit and computing, pervasive computing ( pervasive computing or Ubiquitous Computing) this concept emphasizes and environmental com. Calculation, and the computer itself from the people's sight.In the pervasive computing model, people can at any time and any place and in any manner of information acquisition and processing.

Put forward

Pervasive computing originated in 1988, Xerox PARC series of laboratory research program.In the program the Xerox Research Center (Xerox) PARC Mark Weiser first put forward the concept of ubiquitous computing.The 1991 Mark Weiser in "Scientific American" published the article "The Computer for the 21st Century", put forward formally to pervasive computing ( Ubiquitous Computing).Mark Weiser pointed out : pervasive computing

"The most profound technologies are those that disappear . They weave themselves into the fabric of everyday life until they are indistinguishable from it."

In 1999, IBM is also presented in Pervasive Computing ( IBM called Pervasive Computing) concept, which is omnipresent, whenever and wherever possible can be calculated in a way.Like Weiser, IBM also emphasized the computational resources general exist in environment, people can obtain the needed information and services whenever and wherever possible.

In 1999 the European study group ISTAG proposed ambient intelligence ( Ambient Intelligence) concept.Actually it is with the pervasive computing is similar in concept, but in the United States, often called the pervasive computing, while European some organization is called the intelligent environment.The two formulation is different, but the same meaning, the experimental direction is consistent.

Core ideology

Scientists said that the pervasive computing is the core idea of small, cheap, network processing devices are widely distributed in the daily life of all places, the computing device will not only depend on the command line, graphical interface for human-computer interaction, and more dependent on the "natural" interactively computing device size shrinks to mm or nanometer level.

In the pervasive computing environment, wireless sensor network will be widely popularized in environmental protection, transportation and other fields play a role; body sensor network will greatly promote the health monitoring and interactive development.A variety of new interactive technology (such as tactile display, OLED etc.) will make the interaction easier and more convenient.

Characteristic

Pervasive computing is very extensive, involving technology including the mobile communication technology, small computing equipment manufacturing technology, small computing devices on the operating system technology and software technology.

Intermittently connected with lightweight computing (i.e. computational resources are relatively limited ) is a pervasive computing is the two most important features.Pervasive computing software technology is realized in this environment affairs and data processing.

In the information age, pervasive computing can reduce equipment complexity, make people's lives easier and more efficient.In fact, the pervasive computing is a natural extension of network computing, which allows not only for personal computers, and other small smart device can also be connected to the network, so as to be convenient for people to acquire information and take action immediately.

At present, the IBM has a pervasive computing identified as electronic commerce after another major development strategy, and the beginning of end to end solution of technology research and development.IBM believes that the realization of pervasive computing is the basic conditions for computing equipment is more and more small, convenient for people to wear and use whenever and wherever possible.In a computing device at all times, omnipresent conditions, pervasive computing is possible.

Scientists think that the pervasive computing is a state, in this state, the iPad and other mobile equipment, Google Docs or remote gaming technology Onlive cloud computing applications, 4G or wide area Wi-Fi high speed wireless networks together, clear the " computer " as to obtain digital service media central position.With every car, every camera, computer, each and every watch TV screen has almost unlimited computing power, the computer will completely into a "behind the scenes" so that users do not feel their existence.
