The Development of a Hand-Washing Education System

Abstract

This study develops a system that focuses on proper hand-washing patterns to examine whether hands are being washed properly. By comparing images of hand-washing taken at sinks and the like with model images, it informs users in real-time whether they are using proper hand-washing patterns. Optical flow and skin-color pixel areas are used as feature amounts for recognizing proper hand-washing patterns. SVM (Support Vector Machine) is introduced as the recognition model in this system.
