Contents 1. Introduction
The increase in the power and interactive capabilities of hand held, portable and wearable computing devices, and the technological development originated in the growth of mobile telecommunications through cellular and satellite infrastructure provide the possibility to have wide ranging and continual access to computing and other resources in a variety of contexts. The progress and the quality of information and communication technologies and infrastructures of networking along with multimedia facilities and multi-modal interfacing enabled by the explosive growth in computing power and connectivity, address the issue of universal connectivity and global access to information for wide range of applications. The evolution of information technology and the quality of modern communication technologies are infiltrating our lives, and imposing new structures and linkages not only on human living physical environment but also on human life, working habit and on the internal ecology. Such changes will not only cover gathering and exchanging information but also will cover the way to do business, education, research, medical treatment, space missions, consultation, manufacturing, etc. [1], [2]. Theses changes are forcing us to revolutionize the way towards a rethinking of the physical structures and spaces needed for living, reshaping relationships among professionals and organizations, working, and learning as the need to look for alternative forms of physical movement of people, equipment, records and information, etc. is evolving. Many of human physiological and psychological functions have to adapt and respond to new imperatives.
