Another important aspect to be considered in a smart space is user mobility. Smart spaces should support mobility and integrate computational techniques and devices to enable user interaction with the environment in a transparent and intuitive manner [35].

Research in the area of the smart spaces is quite robust. For more than a decade, researchers have been proposing solutions for the field, such as the work of Johanson and Fox [27], who propose the Event Heap, a collaborative workspace that extends the TSpaces, a tuple space presented by IBM Research [72], in which different applications can publish and receive events of their interest.

Coen et al. [11] present Metaglue, a Java-based programming language developed in the artificial intelligence laboratories of the Massachusetts Institute of Technology (MIT). The goal of Metaglue is to enable the development of smart space applications by supporting a number of specific needs of this type of application, such as interconnecting and managing heterogeneous hardware and software, adding, removing, modifying, and updating components in a system at runtime, as well as controlling the allocation of resources.

More recently, the works in the smart spaces field that have attracted attention are the open source initiatives: openHAB1 and Smart-M3.2 The openHAB (open Home Automation Bus) project aims to provide a universal integration platform for home automation. openHAB is a Java solution, completely based on OSGi,3 which facilitates its goal of enabling the hardware interconnection from several vendors, even if they use different communication protocols. Smart-M3 is a platform that offers distributed applications a shared view of information and services present in ubiquitous environments, based on the blackboard architectural model. Smart spaces are seen as information providers and the applications that make up the smart spaces, in turn, produce and consume information.

The traditional smart spaces discussed in this subsection are referred in this chapter as fixed smart spaces. In distinction to them, the concept of personal smart spaces is presented as follows.
