Programming iSpaces — A Tale of Two Paradigms

Abstract

‘iSpace, the final frontier’ — this parody of Star Trek encapsulates many of our aspirations for this area as, in the longer term, iSpaces are likely to be the key to mankind’s successful exploration of deep space. In outer space, or hostile planetary habitats, it is inevitable that people will survive in wholly technologically supported artificial environments [1]. Such environments will contain numerous communicating computers embedded into a myriad of devices, sensing, acting, delivering media, processing data, and providing services that enhance the life-style and effectiveness of the occupant and, in outer space, preserving human life. Such environments will also include robots [2]. In today’s iSpaces, while human life will not normally be at stake, the underlying principles and technology are much the same. Today our homes are rapidly being filled with diverse types of products ranging from simple lighting systems to sophisticated entertainment systems, all adding to the functionality and convenience available to the home user. The iSpace approach envisages that, one day soon, most artefacts will contain embedded computers and network connections, opening up the possibility for hundreds of communicating devices, co-operating in communities serving the occupant(s). The seeds of this revolution have already been sown in that pervasive technologies such as the Internet and mobile telephones already boast over 200 and 680 million users, respectively [3].
