Presentation
The Influence of Perceptions of Task Difficulty on Use of an Automated Attention Aid
DescriptionIncreasingly, humans are given the choice of having automation present or absent, but they seldom choose optimally. There are hints in this literature that the impact of task difficulty on automation use comes from user perceptions of difficulty, which are not always aligned with objective measures of difficulty. Using a visual search and dynamic decision-making paradigm, difficulty was manipulated and participants were given the choice to use an automated attention aid. Results indicated that automation use was higher when raw accuracy scores were lower, but when using an accuracy score that accounted for chance performance – which would be more difficult for users to calculate – automation use was less calibrated. This provides some evidence for the importance of considering operator perceptions in automation use decisions. Additionally, new survey questions for capturing the difference between trust and self-confidence were tested but did not show better prediction of automation use decisions.
