- Accurate Symmetry Calculation with Normalized Dynamic Time Warping Gait Symmetry Ratio Tobias Steinmetzer Ingrid Bönninger Carlos M. Travieso-González Multidisciplinaria (Ciencias Naturales y Exactas) Symmetry Time Series Gait Asymmetry Wearable Device Dynamic Time Warping (DTW) In this paper we propose a new method for symmetry calculation in wearable devices. The problem in this domain is that only discrete features such as stride length, stride duration, or duration of gait phases are used for the symmetry calculation. However, this can lead to failures, since the use of features can result in partial loss of information from the time series. From this we present a possibility to calculate the symmetry by using Dynamic Time Warping (DTW). DTW uses the complete time series for the analysis and is therefore independent of certain features. 2022 artículo científico 2215-3470 https://www.redalyc.org/articulo.oa?id=475974057047 https://www.redalyc.org/journal/4759/475974057047/ https://www.redalyc.org/journal/4759/475974057047/html/ https://www.redalyc.org/journal/4759/475974057047/475974057047.epub https://www.redalyc.org/journal/4759/475974057047/movil 10.15359/ru.36/1.47 en http://www.redalyc.org/revista.oa?id=4759 Uniciencia application/pdf Universidad Nacional de Costa Rica Uniciencia (Costa Rica) Num.1 Vol.36
