Learning handling principles using inertial sensors and 3d avatar

The performance of the computers “central processing units” (CPUs), “graphics processing units” (GPUs) and of the “inertial measurement unit” (IMUs) is constantly evolving. In this paper, we apply IMUs data to an avatar in a game “integrated development environment” (IDE) to stimulate the learning of the material handler by using feedback. Given the failure of handler training programs [1] that focus mainly on the “straight back, bent knees” safe lifting technique, a new approach called “Integrated Prevention Strategy for Manual Handling” (IPSMH) was proposed in 2011 [2]. It uses movement principles that make it possible to understand many techniques handlers use naturally. The data from Xsens® IMUs full-body system are use, in the IDE Unity3D, to produce feedbacks to the handlers on their activity based on these movement principles. This application uses the data in real time or in post processed treatment.
