This lecture will give an overview on relevant concepts and technologies (such as the history of ubiquitous computing and underlying visions, embedded systems and cyber-physical systems, mobile computing, wearable computing, and wireless sensor networks). It will also deal with more specific subjects (e.g., context awareness, activity recognition, privacy and security issues, research methods in this emerging field). Case studies will also be given during breaks to give more insights in current developments and the lessons and pitfalls that researchers and engineers have met while deploying such novel systems.
