What is a 3D digital twin and what is it for ergonomics?

When capturing the movements of the operators, KIMEA realizes in real time a 3D digital twin of the operator. This week we propose you to revisit this notion of digital twin and especially its contribution in ergonomics.

“When it comes to the digital twin, it all started in the aerospace industry. In order to realize complex tasks, spacecraft are subject to high loads and severe operating conditions, this, during long periods. Since then, digital twins of space stations and space craft have been created to simulate physical reactions, or monitor the functioning of systems, and ensure the safety of crews during exploration.”

The purpose of the digital twin is to create a digital duplicate of an object, a building or a person. It is a kind of virtual copy of the physical world in order to identify problems, to understand how a complex system works.

In our case, which is the one of ergonomics, the digital twin is an aggregate of data that reflects as accurately as possible the gestures and postures filmed. It facilitates access to data (articulatory angles,…). The twin integrates all the necessary biomechanical data and can be customized according to the person’s “history” (weight, height, loads, etc.). With the digital twin, we are then able to predict the areas of the body at risk in terms of musculoskeletal disorders.

So are you interested in a digital twin?
