Rethinking Legibility in Social Robot Hallway Navigation: Impact of Intent Representation and Human Distraction

The paper frames the work as navigationNavigation & LocomotionNavigationMoving through an environment toward a goal.. Start here because it defines what success means and which assumptions the rest of the method inherits.

This paper shows how to make robots navigate hallways in a way that clearly signals their intent to humans (which side they'll pass on), reducing confusion and making interactions smoother even when people are distracted. The key insight is that robots should optimize for 'passing-side legibility' within a controlControl & PlanningControlThe method used to make the robot move the way you want. framework rather than just announcing destinations, leading to 20% smoother human motion and better perceived competence.
