Interface design for an automated combat identification system: Displaying reliability information.

摘要

Users have difficulty relying on automated combat identification aids; however, verbally informing users of the automation reliability has helped them rely on the automation more appropriately. A number of interfaces that displayed automation reliability information in real time were developed and tested. In Experiment I, participants used the interfaces in the IMMERSIVE simulation, a first person shooter game. The results showed that the form of the interface affected both reliance on the automation and sensitivity in discriminating hostile and friendly targets.;The difference in sensitivity and reliance may be attributed to how participants allocated their attention among the displays. In Experiment II, still combat scenes were presented to the participants for 400 or 800 milliseconds (as opposed to 10 seconds in Experiment I) to place additional time stress on attention resources. The results replicated the results of Experiment I, but sensitivity measures showed a dependence on reliability of the automation.
