Bottom-up Investigation: Human Activity Recognition Based on Feet Movement and Posture Information

Human Activity Recognition (HAR) research on feet posture and movement information has seen an intense growth during the last five years, drawing attention of fields such as healthcare systems and context inference. In this work, we tested our 6-activity classes machine learning HAR classifier using a foot-based wearable device in an experiment involving 11 volunteers. The classifier uses a Random Forest algorithm with Leave-one-out Cross Validation, achieving an average of 93.34% accuracy. Targeting at a replicable research, we provide full hardware information, system source code and a public domain dataset consisting of 800,000 samples.
