Chapter 2 INTRODUCTION Intelligent Environments (IEs) are “…digital environments that proactively, but sensibly, assist people in their daily lives” (Augusto et al. 2007). They offer an opportunity to blend a diversity of disciplines, from the more technical to those more human oriented, which at this point in his- tory can be combined to help people in different environments, at home, in a car, in the classroom, shopping centre, etc. One of the hidden and most important assump- tions in IEs is that they are pioneering a transition from techno-centered systems to human-centered Asier Aztiria University of Mondragon, Spain Juan Carlos Augusto University of Ulster, UK Context-Aware Discovery of Human Frequent Behaviours through Sensor Information Interpretation ABSTRACT The ability of discovering frequent behaviours of the users allows an environment to act intelligently, for example automating some devices’ activation. Moreover, such frequent behaviours could be used to understand and detect bad or unhealthy habits. Such a discovering process must be as unobtrusive and transparent as possible. In that sense, the ability of inferring interesting information from sensors installed in the environment plays an essential role in order to provide the discovering process with meaningful data. The importance of this system is clear due to the fact the process of discovering frequent behaviours will totally depend upon the actions/activities identifed by such a system. This development reinforces the link between context-awareness and human behaviour understanding as it can perceive a current situation, compare it to typical behaviour, and diferentiate between the two.
