The University of Tokyo: Ubiquitous Computing

Outline

“Ubiquitous” is used to describe a model of interface and environmental technology in which anybody can be engaged, anytime, at any place.

The ubiquitous concept was initially proposed in 1984 by Ken Sakamura, a professor at The University of Tokyo, as part of the TRON (The Real-time Operating system Nucleus) Project, a project created by Professor Sakamura to develop an ideal computer architecture and network, with ‘computers everywhere’. This was the origin of the notion of ubiquitous in Japan. This principle is reflected in ubiquitous computing, and has been further popularized as ubiquitous computing becomes more widespread.

In 2006, the World Wide Web Consortium , the international standards organization for the world wide web, established workshop on ubiquitous and began a global-wide standardization project.

Ubiquitous computing is a term generated through the idea of applying computing to the ubiquitous concept of “anytime, anywhere, anybody”. Ubiquitous computing has two distinct advantages over conventional information and communication technologies.

The first is that it is able to use electronic devices smaller than ordinary computers. For example, electronic tags and radio-frequency identification (RFID) can be operated via stand-alone silicon chips of just 0.3 mm, and use wireless communications.

The second is that by embedding tiny computers and chips into the environments that surround us, ubiquitous computer enables the automatic recognition of the status of the real-time, actual world, gleaning information that can then be used in various forms of information processing. This is referred to as status information processing.
