Pervasive Technologies, stemming from the pioneering perspective of the Xerox Palo Alto Research Center (PARC) in 1987, introduced the paradigm of ubiquitous computing, coined by Mark Weiser in 1988. This concept seamlessly integrates information processing into everyday objects, promoting efficiency in work practices and communication. The adoption of the experimental system “ubi-comp” and its subsequent implementation at the Olivetti Research Laboratory developed sentient computing, adapting applications to user context changes. This led to the “technology of non-doing” and “global intelligent personalization.” Through miniaturization and the integration of microprocessors into common objects, a new informatics phase emerged, supported by Pervasive Technologies, now pillars of the Internet of Things (IoT). In this perspective, they embody an omnipresent infrastructure for information and communication technologies (ICT), facilitating the interconnection of heterogeneous nodes and optimizing processes in various contexts. In contemporary times, responding to global challenges such as sustainable development and climate change, these technologies emerge as key catalysts for eco-innovations and the transformation towards Green ICT.
