Online posture feedback system aiming at human comfort

Abstract

The objective of this paper is to develop a posture analysis system in such a way that good ergonomics conditions and human comfort are preserved and health risks minimized. This system evaluates human positions during tasks execution and classifies them in good, medium or bad condition in order to avoid health issues. Therefore some ergonomics methods and cases at literature are explored aiming at provide a database with mainly human body angles. Then, a vestment is developed with mechanical and electronic devices using a sort of different sensors to acquire information of these angles. It warns bad positions in real time to the user once the script created considers dangerous postures. To validate this study, preliminary tests are conduct collecting the results and making improvements on the devices with the purpose of avoid alteration in normal tasks execution.
