Online context recognition in multisensor systems using Dynamic Time Warping
conference contribution
posted on 2005-01-01, 00:00 authored by M Ko, G West, Svetha VenkateshSvetha Venkatesh, M KumarIn this paper, we present our system for online context recognition of multimodal sequences acquired from multiple sensors. The system uses Dynamic Time Warping (DTW) to recognize multimodal sequences of different lengths, embedded in continuous data streams. We evaluate the performance of our system on two real world datasets: 1) accelerometer data acquired from performing two hand gestures and 2) NOKIA's benchmark dataset for context recognition. The results from both datasets demonstrate that the system can perform online context recognition efficiently and achieve high recognition accuracy.
