Resumen
This article focuses on prospective challenges that might arise due to the implementation of ubiquitous computing. Users, in traditional computing environments, actively choose to interact with computers. Ubiquitous computing applications are likely to be different they will be embedded in the users' physical environments and integrate seamlessly with their everyday tasks. This vision leads to a set of defining characteristics, requirements, and research challenges for ubiquitous applications. This article identifies some of the key characteristics via a possible real-world scenario and derives the important application design and software infrastructure challenges that must be addressed by the computing research community. The omnipresence of ubiquitous applications is typically achieved by either making the technological artifacts move with the user or by having the applications move between devices tracking the user. In both cases, applications have to adapt to changing technological capabilities in their environment.
