Comparison of a brain-based adaptive system and a manual adaptable system for invoking automation.

Objective: Two experiments are presented examining adaptive and adaptable methods for invoking automation.

Background: Empirical investigations of adaptive automation have focused on methods used to invoke automation or on automation-related performance implications. However, no research has addressed whether performance benefits associated with brain-based systems exceed those in which users have control over task allocations.

An evaluation of an adaptive automation system using a cognitive vigilance task.

The performance of an adaptive automation system was evaluated using a cognitive vigilance task. Participants responded to the presence of a green "K" in an array of two, five, or nine distractor stimuli during a 40-min vigil. The array with the target stimulus was presented once each minute.
