Latent Ergonomics Maps: Real-Time Visualization of Estimated Ergonomics of Human Movements

Improving the ergonomy of working environments is essential to reducing work-related musculo-skeletal disorders. We consider real-time ergonomic feedback a key technology for achieving such improvements. To this end, we present supportive tools for online evaluation and visualization of strenuous efforts and postures of a worker, also when physically interacting with a robot. A digital human model is used to estimate human kinematics and dynamics and visualize non-ergonomic joint angles, based on the on-line data acquired from a wearable motion tracking device.

Automated summary

This article presents supportive tools for evaluating and visualizing the efforts and postures of workers when physically interacting with robots, with the aim of improving the ergonomy of working environments.
