Augmented reality in practice: Virtual training on the VM-X-PAVERMAX from Probst

They are supported in their work by Prof. Dr. phil. habil. Oliver Sträter, head of the Department of Work and Organisational Psychology at the University of Kassel. The CoARtec platform (Collaborative Augmented Reality Technology) developed by the students blends digital content directly into the real working environment, enabling a new form of knowledge transfer – in the sense of a ‘virtual briefing’. 

But what exactly is augmented reality (AR)? AR enhances the real environment with digital information such as 3D models, animations or step-by-step instructions. With the help of VR glasses – including Apple Vision Pro – this content is displayed directly in the user's field of vision and linked precisely to the machine. Components can be highlighted, processes visualised or operating instructions displayed. This offers great potential, especially for complex machines, as connections can be understood more intuitively and processes can be grasped more quickly.
The CoARtec platform aims to support users in commissioning and generally familiarising themselves with machines, especially specialised machines. This should enable new employees or international specialists to develop an initial technical understanding more quickly. ‘The cool thing about the application is that it takes different learning types into account,’ explains David Eich, a student at the University of Kassel. ‘This means that knowledge is not only imparted, but also brought to life.’

The developed application was scientifically monitored and evaluated as part of a bachelor's thesis. Two test groups, each consisting of four Probst employees, underwent virtual training on the VM-X-PAVERMAX and then evaluated it using a questionnaire. The results show that the application basically works as intended. Even an inexperienced person was able to operate the machine after the AR training, which underlines the potential of the solution.

At the same time, it became clear that operating and adapting the virtual elements to the real environment is currently still perceived as very complex. There is further potential for optimisation here, particularly with regard to user-friendliness and practicality in everyday work. The exchange between the university and the company impressively demonstrates the innovative potential that lies in the combination of research and industrial practice. That is why it is only natural for Probst, as an innovative company, to continue to actively support projects like this in the future.
The test clearly shows that augmented reality opens up new perspectives in mechanical and plant engineering – from commissioning and training to service and maintenance processes. The CoARtec platform thus already offers a glimpse into the future of technical qualification. The extent to which such solutions will establish themselves in everyday practice in the long term will become apparent in the coming development stages.
