In Côte-d’Or, virtual reality and motion capture at the service of occupational health

With an HTC Vive pro virtual reality headset combined with joysticks and Unity software, the Côte-d’Or occupational health service, AIST 21, uses technology to better understand the arrangements to recommend to better think of a workspace.

Before, we did 3D modeling in cases of creation or redevelopment of premises but we wanted to go beyond the plan and have something less fixed“explains Pierre-Antoine Martin, ergonomist within the association.

Google Sketchup then Unity

In order to realize the heights of furniture, the constraints of movement in space, he first uses the Google Sketchup design software to recreate the spaces, designing or importing the necessary objects, before transferring them to Unity. “By relying on virtual reality and by having the new layout tested by employees and also the manager, our proposals are better understood and more easily accepted.“, rejoices the ergonomist.

Whether they operate in an industry or a call center, AIST 21 identifies the constraints and needs of operators to design a solution, from the existing or even from nothing. “We develop the project with the people concerned before testing it in virtual reality to make the last adjustments, those that the paper did not allow to consider“completes the ergonomist. In response to a visit to a company, to a request from the employees or the manager, the AIST carries out a study, supported financially by the annual contribution of the company, within the limit of 4.5 days of Work Beyond that, the association invoices its service.

Measuring angulation at work

The AIST 21 also uses Motion Capture and has the Captiv software, developed by TEA, Tech Ergo Applied. The company, which has positioned itself as the world leader in human measurements in complex and real environments for more than 30 years, is located near Nancy (Meurthe-et-Moselle). The Tea Captiv T-Sens Motion is a wireless sensor with a four hour battery life for measuring human body movement.

For ergonomist Pierre-Antoine Martin, Motion Capture specifies the analysis of a workstation. “Rather than measuring the repetition of a gesture by observing an operator for hours or watching a video to extract a screen impression to show a posture, we have more reliable data that we will better process thanks to the software. .“The professional can more easily see the problematic angulations that the body undergoes and measure the impact that a change in height in the furniture or the movement of a device can have. The final objective is to reduce the number of accidents or problems. ” work stoppages by providing better comfort to employees in carrying out their task.

Finally, we will offer both the simplest and cheapest solution as well as the most extreme solution such as automation so that the manager can make his decision according to his situation.“. Pierre-Antoine Martin recognizes, however, that sometimes the solution does not exist, the task to be improved leaving little room for maneuver. Both technologies have been available at AIST 21 since December 2019 to support companies, even if the health crisis prevented them from taking full action, limiting access to businesses on the one hand and to the association’s offices on the other.
