Compasses have been used for centuries to express directions and are commonplace in many user interfaces; however, there has not been work in human-robotic interaction (HRI) to ascertain how different compass visualizations affect the interaction. This paper presents a HRI evaluation comparing two representative compass visualizations: top-down and in-world world-aligned. The compass visualizations were evaluated to ascertain which one provides better metric judgment accuracy, lowers workload,

The results agreed with the existing principles relating to 2D and 3D views, or projections of a three-dimensional scene, in that a top-down (2D view) compass visualization is easier to use for metric judgment tasks and a world-aligned (3D view) compass visualization yields faster performance for general navigation tasks. The implication for HRI is that the choice in compass visualization has a definite and nontrivial impact on operator performance (world-aligned was faster), situational awareness (top-down was better), and perceived ease of use (top-down was easier).
