Reducing the Impact of Sensor Orientation Variability in Human Activity Recognition Using a Consistent Reference System

Reducing the Impact of Sensor Orientation Variability in Human Activity Recognition Using a Consistent Reference System

Sensor- orientation is a critical aspect in a Human Activity Recognition (HAR) system based on tri-axial signals (such as accelerations); different sensors orientations introduce important errors in the activity recognition process. This paper proposes a new preprocessing module to reduce the negati...
