KCAR: A knowledge-driven approach for concurrent activity recognition

Complete article Abstract: Recognising human activities from sensors embedded in an environment or worn on bodies is an important and challenging research topic in pervasive computing. Existing work on activity recognition is mainly concerned with identifying single user sequential activities from well-scripted or pre-segmented sequences of sensor events. However a real-world environment often contains multiple users, with each performing activities simultaneously, in their own way and with no explicit instructions …Read More

As it is the case in many projects, the initial idea for the FourByThree project came from a brainstorming discussion, in this case, between the project coordinator Iñaki (Ik4-TEKNIKER) and myself. I mentioned that we had just recently developed a new generation of actuators (see Fig. 1) for our exoskeleton in the frame of the project CAPIO (funded by the German Federal Ministry of Research and Education, BMBF, from 01.01.2011 …Read More
