Abstract: Two experiments were conducted to assess the effects of navigation display modality on navigation performance, situation awareness, mental workload, and modality preference. Directional cues to a series of waypoints were provided visually, aurally, and tactilely in the within-subjects design. Each experiment was performed in a virtual environment by U.S. Army Soldiers, 14 in the first experiment, 18 in the second experiment. Results from both experiments indicate that augmented visual displays reduced time to complete navigation, maintained situation awareness, and drastically reduced mental workload in comparison to the other display modalities.
