Wearable computing is a shift in computing paradigm. Computers are no longer machines separate from the persons using them. Instead, they are an unobtrusive extension of our very bodies, providing us with additional ubiquitous sensing, feedback and computational capabilities. This opens new possibilities: context-aware smart-assistants that react to our activities, emotions, or social interactions to provide just-in-time assistance.

Prof. Roggen presented some of the work done at the University of Sussex Sensor Technology Research Centre along new sensor modalities (e.g. electric field sensing), methods for opportunistic context recognition, and how to scale up activity sensing to crowds. Finally, he concluded mentioning some ongoing initiatives and new themes to explore in the future.
