Riassunto
Automatic Identification of Sensors on human body is a time consuming task that needs a long and accurate preset. Camera system and wired inertial sensors can access human movement with a good accuracy but the number of activities that can be performed is limited because they cannot be used without a prepared room and technicians.
In this work, a way to automatically identify sensors position on human body is proposed.
Data were recorded in static and dynamic condition at different height levels using an Xsens MTw development kit with several configurations in order to analyze the appropriateness of sensors and changes in sensitivity at different heights. Through a pressure components analysis of internal and external sources of pressure changes and a height resolution analysis it was possible to say if pressure sensors can be used to perceive differences in height on human body and contribute in identifying on which body segment pressure sensors were placed.
