A first-class HMI needs to be comprehensible, clear, detailed and intuitive. Naturally, the design should be appealing and pragmatic. But this alone is not enough. To make an average user interface a real eye-catcher when it comes to usability, a number of other factors must be fulfilled. After all, the success of a technical product no longer depends solely on reliability, price and service life. As a result, the users' requirements move more than ever into the field of focus.

At innovation mecom, we have already been honoured with several renowned awards in the field of HMI design - including the German Design Award and the Red Dot Award. For the two examples shown here, we demonstrate how an excellent HMI design not only saves the user time, but can also provide a competitive advantage for entrepreneurs.


Case Study 1


The combination of intuitive usability, coupled with high efficiency and cost savings, while at the same time expanding the competitive advantage, will gain in importance and gain momentum as digitalization progresses. For this reason and because of our passion for digital content, we have been researching the benefits of HMI designs for years.

In terms of usability, the visual temperature controller can also be emphasized. Instead of covering the desired number with a finger, it slides up the display so far that it remains visible to the driver at all times. Another prime example of excellent usability in this context is the adaption of the haptic feedback. If the driver wants to increase the temperature, the haptic feedback (in the form of vibrations) is more noticeable than when the temperature is lowered.

Case Study 2


With the HMI design for the Hyundai Showcar, the Korean car manufacturer pursued two goals, which we were able to unite in each of the displays thanks to sophisticated design. A three-dimensional visual experience that, thanks to the most innovative technology, both increases driving pleasure and allows the drivers' to maintain their concentration on the road, where it belongs. In total, the content was developed for four displays. These include two steering wheel displays (Haptic Feedback Touch Control) for navigation, a Haptic Display (2D) and the Multi-Layer Display (MLD®). The HMI design is characterised by the harmonious interaction of the technical components, and by the fact that the users' needs have been placed at the centre of the design.

The 3D viewing experience of the MLD® results from the superimposition of two display levels. What is truly remarkable here, is the sorting according to relevance. For example, if the driver is in a 30 km/h zone at high speed, a 30 km/h warning symbol will illuminate; first small, as it is shown on the back of the two display levels. However, if the driver does not adjust the speed, the 30 km/h symbol will be displayed significantly larger on the front display.

This is the operation description from a technical point of view. What the driver experiences in real life, however, is a real 3D experience. With this, elements move freely through the room towards them. This can be used to draw the drivers' attention to to the fact that they are speeding. When the tempo has been adjusted or the car has left the zone, the message disappears again.
