With digitization and automation, machine operation is increasingly controlled by software, making traditional hardware buttons less important. In addition to cost savings and increased flexibility, this change also means more user-friendly operation. However, challenges such as real-time capability and haptic feedback must be overcome to ensure safe and reliable control.
In this article, we present the six most important factors in favor of integrating hardware controls into software.
1. Advantages of digitalization: cost reduction and flexibility
One of the key advantages of digitalization is the drastic reduction of hardware variants, which are normally necessary for different machine types. Software solutions enable quick adaptation of operation by simply adding or changing functions via updates. This reduces the costs for production, storage and maintenance. For new functions, for example, buttons can be added to the software, whereas hardware solutions would often require additional keys. Unnecessary buttons can also be hidden in software solutions, which increases the clarity of the user interface.
2. Real-time capability as the key to efficiency
In industrial applications, real-time capability of operation is of crucial importance. Machine operators must be able to rely on a fast and reliable system response. Here, the combination of a main processor and an additional microcontroller, as in KEBA's Real Time Widget technology, offers a solution that ensures minimal transmission times. This ensures that signals are processed in real time and that the machine's efficiency is maintained. The operating system cannot cause delays as it would otherwise be able to due to the Real Time Widgets. The Real time Widgets technology was one of the aspects that convinced the machine tool manufacturer Pfiffner to work with KEBA.

3. Force feedback: haptic feedback for safe operation
While conventional touchscreens are frequently used for machine operation, they have the disadvantage of lacking the haptic feedback provided by classic hardware keys. In industrial applications, where machines are often operated “blindly” – i.e. without looking directly at the operating panel – this increases the risk of operating errors and thus the error rate. Operators could inadvertently press the wrong key, which can lead to serious malfunctions.
Force feedback technology solves this problem by providing tactile feedback. The system not only registers every touch, but also triggers an action only after a certain pressure point is reached. This simulates the familiar feel of a hardware button and enables safe operation, even without constantly looking at the panel. The technology thus brings the necessary haptics to modern, software-based interfaces. German machine manufacturer "Schwäbische Werkzeugmaschinen" relied on KEBA's force feedback technology for its project to bring machine operation “under glass”.

4. Adaptability through software updates
Another advantage of software-based user interfaces is the option of expanding or modifying machine functions through software updates. This reduces downtime and makes it easier to adapt machines to new production requirements. By shifting these functions to the software, companies can flexibly expand their machines and respond to future requirements without having to replace hardware. This adaptability not only increases the service life of the machines, but also reduces long-term costs.
5. Modern user interfaces and design advantages
Digitalization not only brings functional advantages, but also improvements in user-friendliness. Software-based solutions make it possible to develop modern, intuitive and adaptable user interfaces. Unnecessary or inactive keys can be hidden, keeping the user interface tidy and organized. In addition, these panels can be made more visually appealing, similar to modern smartphones. This improves the user experience and makes it easier for operators to interact with the machine. A simple and visually clear user interface reduces the potential for errors and enables safer operation – even for less experienced users. This is particularly important to ensure that machines can be operated reliably and without extensive training, even when staff are in short supply.
6. Future-proof and flexibility
The future of industrial automation lies in flexibility. User interfaces must be able to adapt to new requirements without the need for expensive hardware changes. Force feedback technology combined with software-based solutions makes it possible to design machines that remain competitive in the long term. The flexibility to replace hardware components with software is an important step towards more efficient, cost-effective and future-proof production.
Conclusion: Digitization simplifies the user interface
Moving hardware keys to software offers numerous advantages, including cost savings, flexibility and user-friendliness. With the right technology, the challenges of digitalization, such as real-time capability and haptic feedback, can be overcome. The digitalization of user interfaces is not only a way to increase efficiency, but also the basis for future-proof production. Companies that rely on these technologies can adapt their machines to constantly changing requirements while reducing their operating costs.
