3D Compass Visualization
This project compared two representative compass visualizations: top-down and in-world world-aligned to ascertain which one provided better metric judgment accuracy, lowers workload, provides better situational awareness, is perceived as easier to use, and is preferred. The evaluation results are in agreement with existing results regarding the effects of 2D and 3D views on the operators’ ability to complete different tasks. The implication to human-robotic interaction from these results is that the choice in compass visualizations has a definite and non-trivial impact. In general, the world-aligned compass resulted in faster task performance; whereas, the top-down compass provided perceived situational awareness and was perceived easier to use. Our results imply that a top-down compass visualization is appropriate for metric judgment tasks and an in-world compass visualization is appropriate for navigational tasks. A single compass visualization may be inappropriate for all HRI tasks, specifically tasks that combine metric judgment and navigational activities into a single task. Compass visualizations for these combined tasks require further evaluation.
