Indoor landmark selection for route communication: the influence of route-givers’ social roles and receivers’ familiarity with the environment

Abstract

When conveying information about routes to follow in complex environments, human routegivers adapt to route-receivers' familiarity with the environments in their choice of landmarks. Meanwhile, as route-givers themselves have experienced the environments within a social role, the landmarks they select may also differ significantly. This research investigated how these two factors influence landmark selection when communicating routes in indoor environments. Two groups of participants were recruited to conduct indoor landmark selection experiments for familiar and unfamiliar route-receivers in a multi-functional university building. The results show an interaction effect between these factors in indoor landmark selection. These findings lay an empirical ground for developing human-centered mobile navigation systems that can adapt to users' social roles and their familiarity with the environment.

Using street-view panoramas to model the decision-making complexity of road intersections based on the passing branches during navigation

“…These signals serve as critical references for performing navigation tasks, supporting navigation communications, and helping to identify the right spot for making the turning decisions (Lovelace et al, 1999). Furthermore, space syntax (Hiller andHanson 1984, Hiller andPenn 2004) was employed to analyze the road network attributes like choices, integration and depth distance for further quantifying the road complexity structurally, especially in indoor navigation systems (De Cock et al, 2021;Zhou et al, 2021). In addition to research focusing on the structural complexity, several studies have focused on the visual complexity of the environments.…”
