Ubiquitous Computing

Internet-enabled mobile phones and Personal Digital Assistants that communicate wirelessly with other devices in their vicinity are only the first indications of the coming "post-PC era". Initially, the main aim is to permit access to information of any kind from anywhere, at any time, evidenced by the current efforts of industry to integrate mobile and wearable information appliances into Web-based business processes and electronic commerce scenarios. In the long term, however, the continuing technological trend may result in the computer merging with typical everyday objects so that it becomes literally invisible.

Even if the physical world is not transformed into a single huge interactive computing platform as quickly as some experts believe, it is clear that, with the increasing computerization and networking of everyday objects, we are becoming ever more dependent on reliable IT systems. Hence, adequate IT concepts, well-trained experts and computer science as a whole will play an even more important role in the future than they do today.

This issue of UPGRADE is dedicated to the current trend towards the "computerisation and networking of all things", which is often denoted by the terms ubiquitous computing or pervasive computing. It aims to provide an insight into the techniques, expectations and background of this exciting development, leading to a future pervaded by information technology.
