As we step into the era of the Internet of Things (IoT) where devices communicate with other devices to support tasks of humans, ubiquitous interaction as was envisioned by Mark Weiser is becoming a reality. The concept of a smart space is used as a key phrase to refer to such personal interactions in a technologically enhanced space with networked electronic devices producing and consuming information. Smartness here refers to a (collective) behavior of a large number of devices perceived as advanced and useful in some sense.

Smart space implementations that are specialized in a particular application domain are common in practice. Among various types of smart spaces that are available, Smart Lighting infrastructures get a unique position since lighting (and thus a dense lighting infrastructure) is omnipresent inside all buildings and in cities. As a smart space, Smart Lighting goes beyond the typical functionality of just providing sufficient illumination in the environment. The research in this field envisions a tradeoff between user control, sensing and intelligence, resulting in an interactive user experience with networked, context aware, personalized lighting services. This is a major paradigm shift that will potentially change the way we use lighting.

The goal of this special session is to bring together members of the industrial and scientific communities that contribute to the development of Smart Lighting solutions and to provide an overview via knowledge exchange. This overview will provide further insights into the problems solved at this stage, a comparison of the various approaches used, and lessons learned.
