Guiding the Operator's Attention Among a Plurality of Operator Workstation Screens

In the age of extensive industrial digitalization, industrial operators are facing increasing pressure from the growing amount of data being delivered to industrial control rooms. Humans' limited perceptual system is the bottleneck when it comes to processing large volumes of information. Too many screens crammed with textual and numerical data make the user disoriented in information potentially leading to fatal mistakes and insufficient situation awareness. This paper explores possibilities of guiding operators' attention to the most urgent information by means of visual aid systems. In this work, two concepts of such systems were developed and evaluated in a lab environment. The evaluation results indicate a clear benefit of using the developed concepts.
