“…In this paper, we present data collected to provide insights about low-level human-computer interaction in the control room (Hildebrandt & Eitrheim, 2015). Such data can help assess if the control room interfaces support efficient information gathering, or if they create obstacles and error opportunities for the operators (Hildebrandt & Fernandes, 2016).…”

An important aspect in evaluating modern digital control rooms is to assess if control room interfaces support efficient information acquisition by the operators. Interface efficiency is an indicator of good interface design and can therefore help in judging if conditions are right to support good operator decision making and maintenance of situation awareness. This report describes the results of a micro task data collection where 12 operators each performed 36 relatively simple control room tasks. Performance time for each task was measured. Tasks were categorized according to the type of component or system that was used, as well as if they were knowledge-based or simple identification. Results show consistently low performance times for most components. As expected, knowledge-based tasks required more time.

“…One approach to this problem is to present the user with a series of small tasks, and to measure the performance time and accuracy. By aggregating performance data across a larger pool of such micro tasks (Hildebrandt and Eitrheim, 2015), the investigator can identify strengths and weaknesses of different design solutions.…”

Micro tasks are small knowledge probes that can provide speed and accuracy data about how well a user interface (UI) supports work tasks. We present a software system that supports researchers in authoring, managing and conducting micro tasks studies. The system supports the generation of different types of micro task questions, provides tagging functionality, can exchange data with external systems such as simulators, is fully integrated with eye tracking, presents micro tasks questions to participants, allows for online observation, and stores responses in a data base.

“…To address this issue, Hildebrandt and Eitrheim (2015) proposed a high-density data collection method called micro tasks (MTs) to supplement traditional scenario-based methods. It is important to emphasize that MTs are not intended to replace scenario-based methods, but work together with these more contextual methods by providing large amounts of data about the efficiency and reliability with which operators can use the control room interfaces.…”

“…

INL contracted IFE to develop custom software functionality to support INL's control room simulator data collections. The tool described in this report provides functionality for authoring, managing and executing so-called micro task data collections (Hildebrandt and Eitrheim, 2015), where operators receive a long list of operational tasks, and the speed and accuracy of their response is measured. The tool consists of an editor, player and observer module.
