HMI prototyping
HMI prototyping that you can feel – UX720°
When developing HMIs for our customers, we work with BUSSE Design+Engineering GmbH regularly with embedded systems. The particular challenge:
The meaningful connection of physical controls (buttons, joysticks, rotary knobs, membrane keyboards, etc.) with digital display content.
For a good user experience, it must always be clear:
Which key controls what?
On a laptop or PC, the usability of such an HMI is difficult to evaluate—because the haptics are missing there. Products are three-dimensional, have edges, corners, and need to feel right.
💡 Our solution: pragmatic, fast, and effective.
With simple components like USB encoders (primarily used in the maker scene and by retro gaming enthusiasts) and push buttons, many interactions can already be realistically depicted.
We create the screens in Figma, allowing content from the concept and design to be directly transferred into a clickable dummy.
In combination with rapid prototyping via 3D printing, functional prototypes are created—without complex molds or programming.
🚀 And what if it gets more complex?
No problem. In our HMI Lab, we also realize sophisticated prototypes with Arduino, Raspberry Pi, and connected CAN bus components.
And if your system needs to function while in motion, we test it on our Motion Table – your project will be thoroughly shaken.
