When receiving assistance from an automated aid, human operators do not necessarily perform better than without the automated aid. The current work explored the impact of integrating the automated aid with the task information in low prevalence conditions. Specifically, this work compares displays where the automated aid was integrated with task information in general or with more meaningful task information. Subjects performed a speeded judgment task with the assistance of an automated aid, varying in display type, difficulty, and prevalence. Results indicated that there was no effect of display type or prevalence on human temporal performance, and that the effect of low target prevalence on miss rates weakened in the context of an automated aid. Automated aids could be used in real world contexts to alleviate the effects of low target or target prevalence. Designers should consider the potential utility of automated aids for low prevalence tasks in real world applications.
