About

Florian Lettner is a researcher in human-computer interaction and industrial automation, with a focus on the usability of touch-based interfaces for machine control. His work addresses the critical challenge of designing intuitive and efficient touch panels for teach pendants—devices used to program and operate industrial robots and machinery. In his most-cited paper, "Logging and visualization of touch interactions on teach pendants" (2014, 4 citations), Lettner introduces methods for capturing and analyzing user touch interactions on these specialized interfaces. This contribution provides a foundation for evaluating and improving the user experience in industrial settings, where traditional physical buttons are being replaced by flexible touch screens. By enabling detailed logging and visualization of touch behavior, his research helps identify usability issues and informs better interface design, ultimately enhancing operator efficiency and safety. Lettner’s work bridges the gap between HCI principles and real-world industrial applications, offering practical tools for developers and engineers. His contributions are particularly valuable as automation and robotics continue to evolve, making human-machine interaction more critical than ever.
