The Future of Human-Machine Interfaces: Beyond Touch

Case Study Overview

Smartphones have shaped the general image of a modern human-machine interface (HMI): a touchscreen with multi-finger operation. Although this intuitive interface can be used universally, there are many applications where it has its limitations: For example, when it comes to hygiene, any touch on a control surface used by more than one person is a disqualifier. Displays also reach their limits at very high ambient brightness levels. If you literally have your hands full, touch is not the answer. If the task requires precise observation of a process, such as positioning a heavy load with a crane, the distracting view of the display should be avoided for safety reasons.

In recent years, a number of alternative operating concepts have been developed, but they have only been implemented in a few cases for cost reasons. Thanks to the performance and versatility of modern embedded computing modules, these concepts can now be implemented cost-effectively to improve the operation of devices and machines. Advances in artificial intelligence (AI) and connectivity are particularly beneficial.
