FAQ: Frequently asked questions about HMI complete solutions

A human-machine interface (HMI) refers to any form of user interface via which a person can interact with a machine, device
or interacts with a technical system. It is used to record inputs and display feedback from the system in an understandable way.
HMIs can have a very simple design – with individual buttons or status LEDs, for example – or complex systems with touchscreens and displays,
tactile controls and integrated electronics. They form the communicative level between people and technology.

An HMI solution (human-machine interface) is made up of several coordinated components. Depending on
These can vary depending on the application and industry. An HMI solution typically comprises the following components:

Control elements
These include buttons, touch surfaces, membrane switches, keypads, rotary encoders or combined input systems via which the user can interact with the
interacts with the machine or device.

Display and visualization elements
Displays, LEDs, illuminated fields or symbols for displaying statuses, measured values and process information.

Electronics and control
Printed circuit boards, controllers and interfaces for signal processing, communication and connection to the higher-level control system or the
System.

Mechanics and housing
Front panels, carriers, seals and housing solutions that ensure protection, stability and secure integration into the overall device.

Surface design and labeling
Layout, symbols, colors and haptic elements that support usability, ergonomics and recognition.

Software and system integration (optional)
Depending on the project, the HMI solution may also include firmware, drivers or support with system integration.

The main challenges in HMI projects are the complex system integration, dynamic user requirements and the
Ensuring long-term maintainability. The integration of different hardware and software components requires specialized know-how. It is also crucial to identify user expectations at an early stage in order to ensure acceptance. The entire life cycle also requires forward-looking planning of updates and upgrades.

A customized HMI solution is recommended when standard products have specific requirements in terms of functionality, design or
environmental conditions. This applies in particular to applications in extreme operating environments, where it is necessary to
brand integration or complex workflows. A customized solution is also available for connecting proprietary legacy systems.
advantages, as it can be optimally adapted to the intended use and future expansions.

Sustainability in HMIs depends on the choice of materials, energy efficiency and recyclability. Recyclable or biodegradable
materials reduce the ecological footprint. Optimized energy use during operation and modular construction methods for
The extended service life also strengthens the ecological balance.
