Research

Human activity is considered to be one of the most important ingredients of context awareness and ubiquitous computing. During my PhD I focused mainly on the recognition complex activities based on wearable sensors. By spotting isolated gesture-alike events in a continuous data stream, probabilistic temporal models are used to compose such events into higher level activities such as daily routines, or multi-step construction tasks. Besides my main research direction, several related projects evolved, which are listed on the publication page.
