Book excerpt: Visual search tasks are known to be cognitive capacity demanding and therefore may be improved by training in an augmented reality (AR) environment. During the experimental task, 64 participants searched for enemies (while cued from visual, auditory, tactile, combinations of two, or all three modality cues) and tried to shoot them while avoiding shooting the civilians (fratricide) for two 2-minute low-workload scenarios, and two 2-minute high-workload scenarios. The results showed significant benefits of attentional cueing on visual search task performance. These benefits were revealed by improved performance in reaction time and accuracy from the haptic cues alone, auditory cues alone, and the combination of the visual and haptic cues together. Fratricide occurrence was shown to be amplified by the presence of the audio cues. The two levels of workload produced differences within individual's task performance for accuracy and reaction time. Accuracy and reaction time were significancy better with the medium cues than all the other cue * specificities and the control condition during low workload and marginally better during high workload. Cue specificity generally resulted in better accuracy and reaction time with the medium cues.
