Augmented Reality in Event Technology

Interactive 3D models as operating tools for complex constructions and systems

How do users of complex technology and products in the stage and event sector benefit from augmented reality? In addition to possible time savings when setting up complex machinery, the main focus here is on increasing safety through a greater understanding of the correct operation. As a basis for a practical examination of the requirements of such an installation aid and for discussion with the various stakeholders and dialogue partners, a first functional prototype for the AR-supported setup of a curtain rail was developed in close cooperation with the company Gerriets.


  • How can XR technologies be used to improve and
    facilitate the daily work of event technicians?
  • What tools are needed to increase safety on stage?

Based on the question of how work safety in the stage area can be increased through the use of augmented reality, we first outlined basic application scenarios of AR technology in the context of event technology. Thus, in workshops with industry partners of the DTHG, ideas emerged for the use of augmented reality in the remote maintenance of control technology, as support through hazard recognition in safety-relevant work and as a construction aid in the assembly and dismantling of complex technical stage decorations.

Due to the technical feasibility, we have dedicated ourselves to a more in-depth investigation of an augmented construction aid. Highly complex equipment is used in the event sector and on theatre stages. The technologies and products used are so diverse that their operation cannot be taught comprehensively in training. In addition, assembly and operating instructions available as paper documents are often too unspecific and – especially in the working environment on stage – impractical to handle. This is where digital instructions can support the work of stage technicians and create a decisive added value through the increased readability of digital 3D models.

We have chosen the TRUMPF 95 curtain rail from Gerriets as an exemplary product. The system is used worldwide and several dozen kilometres of this type of rail are sold and installed every year. Before we devoted ourselves to developing the digital instructions, we first took a close look at the analogue product. Under the guidance of Andreas Gause (Head of Marketing & Key Account Management at Gerriets), we assembled and disassembled a rail several times and created an overview of all the operating steps that a construction aid requires. Decisive for the successful assembly of a curtain rail is the sequence in which the elements are assembled. In addition, it was possible to understand in the analogue which individual module types the module set „curtain rail“ consists of. Since augmenting analogue objects with digital content requires an understanding of the analogue material, this practical workshop was an essential step in the project process.

The result was a first functional prototype for the AR-supported construction of a curtain rail: the instructions in the form of an interactive website guide the user through the construction in ten simple steps after an overview of all the parts and tools used. A short accompanying text (theoretically also possible in several languages) describes the processes, points out possible pitfalls and reveals tips and tricks. The individual construction steps are shown as three-dimensional animations and can be called up by the users one after the other. The viewing angle and zoom factor can be determined by the user.

The implementation as a website makes it possible to change or improve the instructions afterwards and then quickly pass them on to the users – without having to update the application on the end devices. By using the relatively new WebXR interface, the website and assembly instructions can be displayed on a variety of different devices. On the one hand, the technology makes it possible to display 3D objects on conventional screens (for example, on a computer or tablet), and on the other hand – through the use of augmented reality glasses or the AR function of a smartphone or tablet – to „project“ them immersively into one‘s own environment.
