Paragraph starter
The reliability of human interaction with safety-critical interfaces in automated systems is a significant concern. Research by Zehetner et al. (2021) demonstrates that eye-tracking technology can provide objective quantification of user perceptibility and usability. Metrics such as fixation count and duration on specific interface areas were found to be strong indicators of whether users are attending to critical safety information, while fixation deviation offered insights into usability. This highlights the value of employing such empirical methods to validate and refine the design of human-machine interfaces, ensuring enhanced safety outcomes in complex operational environments.
