This research is aimed at testing factors that affect human trust and reliance on individual combat identification systems, thereby helping people better utilize this technology. This research proposes a new method to measure reliance on automation. This measure was used effectively in two experiments, and demonstrated several advantages over previous methods.;Experiment I shows that participants had difficulty in estimating the reliability of the 'unknown' feedback from these systems. Providing the reliability information led to appropriate reliance on that feedback. Experiment II shows that participants' trust in the 'unknown' feedback was influenced by the system's activation mode and the 'unknown' feedback form, but their reliance on it was not affected. This research has implications for the design of interfaces for individual combat identification systems and the training of infantry soldiers. It also recommends that future studies exercise caution in establishing the ecological validity of the simulated systems. |
