Hardegger, Michael

Michael Hardegger studied electrical and biomedical engineering at ETH Zürich and ANU Canberra. After graduating in 2010 he worked for the ABB research center in Dättwil and started his PhD at the Wearable Computing Lab in December 2011. His main interests are rehabilitation engineering, pervasive computing and indoor pedestrian tracking with wearable systems (ActionSLAM).

ActionSLAM

ActionSLAM makes use of a single foot-mounted IMU to keep track of the user's path, while observations of location-related actions (door-opening, sitting down, etc) compensate for accumulated drift errors in a particle filter framework.

This video shows ActionSLAM applied to a dataset simulating daily life. In green, the current ActionSLAM path and position estimate are depicted. In cyan the posterior path (of the full recording) position estimate is shown, and in magenta the ground truth position (where available; from video). Detected landmarks are plotted in yellow. The shape indicates the action type of a landmark.
