Augmented Reality Transformer App for a German mechanical engineering company

A well-known German conglomerate, with a focus on automation and digitization in industry, infrastructure for buildings, decentralized energy systems, mobility solutions for rail and road traffic as well as medical technology, wanted a convenient and clear way of presenting transformers and the associated data in meetings. The app creates a virtual twin of a real tranformer, which is equipped with a large number of sensors.

Data is displayed that was extracted from a company owned cloud. It provides live data via a WebAPI. Various data are highlighted on the 3D model, e.g. Dimensions, running fans, sensor placement and temperature distribution on the various coils using a heat map. Individual components can be inspected more precisely in 3D. Additional functions support the evaluation of the data and enable better recommendations for action.

Applied Skills:
  • Holistic planning
  • UX Design (Wireframing in Adobe XD)
  • UI Design (Assets generated in Adobe Illustrator)
  • Interface competence for the integration into Unity

The challenge in designing this app was to display a lot of data without overwhelming the user. 

That's why I've structured the content in windows that can be minimized or shown in full, depending on what information is required at the time.

At the client's request, I designed the UI elements so that they clearly relate to the corporate identity of the group.

There are two transformer models in the first version of the app. This list can later be expanded to include additional models and prototypes.

After the environment has been scanned, you can place the transformer anywhere and reposition it later.

The app obtains sensor data from a real transformer and visualizes it in real time.

The user can adapt the interface according to individual needs. The modular system allows selected data to be presented.

In addition, the app has a PDF reader that can be used to read the manuals for the transformers.


The app met all the requirements, showed the complex data in a clear way and proved to be very useful in meetings. Therefore, the app received excellent feedback.
