(Don't) Mind the Step

It is well established that the presence of other people and the physical traces of their activities impact our navigation decisions, e.g. following a path in a park where trails are worn by frequent passage. Here we investigate such effect within a digital setup where social cues are displayed on the floor. We contribute the first lab study (n=24) investigating how social cues, presented as footprints on an interactive floor display, can impact navigation decisions. We particularly explore two task-based scenarios: exploration and search. A direct comparison of path choices did not reveal significant effects in both tasks but a further qualitative analysis showed that social cues affected path choices depending on how participants interpreted them. Additionally, results revealed a pattern of direct decision-making behaviours when social cues were present. We discuss how these insights can contribute to designing engaging floor interfaces that guide navigation decisions using social cues.
