We report an experiment which investigated the performance and workload effects associated with the functional grouping of automated displays in a multi-task flight simulation. Eleven rated pilots performed tracking, systems monitoring, and target acquisition sub-tasks in manual conditions and when the targeting task was automated. In the latter condition, the target acquisition display was relocated either proximally, distally, or neutrally with respect to the functionally similar, systems monitoring display. It was hypothesized that an automated task display relocated near its functional equivalent (the proximal condition) would result in increased performance efficiency and lower perceived workload compared to the other relocation positions. An advantage for adaptive automation was confirmed with pilots exhibiting less tracking error, lower monitoring response times, lower target response times, and increased percentage of target responses during automated compared with manual conditions. Results did not confirm the hypothesized benefits for display location. However, when interpreted within the Proximity Compatibility Principle framework where both perceptual and processing proximity are recognized, results confirmed an advantage for the functional grouping layout of the display. Specifically, the proximal grouping condition was the only condition that resulted in both performance and workload benefits. Some observations on the implications for display design in systems using automation are provided.
