Ubiquitous: precisely this word is used to describe one of the most popular topics in the computer science nowadays: ubiquitous systems.

Wikipedia gives the following definition: that is a model of a human-computer communication when the information is processed by different local midget computers integrated into objects around us. This concepts extend the standard human- computer interaction we used to dealing with desk- or laptops. It is called a "post-desktop" evolutional cycle of information technology when we move first from mainstreams to personal computers and now to AI embedded into everywhere to serve our depending on the current request and context. Of course we started to move that way long time ago, after we god mobile phones, PDAs and so forth that could be integrated and can help us to get or post information ...

BUT ...

This paradigm is actually something bigger than that. It breaks out from the complexity of using all those systems and defines that communication should be transparent and even seamless for the human.

A typical example is so called „smart house”, which is able to recognise movement of a human and turn on/off lights along his/her path, react on voice commands or prepare the house for owner’s return from the office by increasing the average temperature in the house, turning on TV on the channel the owner likes etc).

The following terms are used very often with „ubiquitous systems”: Context-aware systems and RFID.
