ABSTRACT

Despite the increased research interest in wayfinding assistance systems, research on the appropriate point in time or space to automatically present a route instruction remains a desideratum. We address this research gap by reporting on the results of an outdoor, within-subject design wayfinding study ($N=52$). Participants walked two different routes for which they requested spoken, landmark-based turn-by-turn route instructions. By means of a survival analysis, we model the points in space at which participants issue such requests, considering personal, environmental, route- and trial-related variables. We reveal different landcover classes (e.g., densely built-up areas) and personal variables (e.g., egocentric orientation and age) to be important, discuss potential reasons for their impact and derive open research questions.

摘要

尽管对寻路辅助系统的研究兴趣日益增加，但对自动呈现路线指令的适当时间或空间点的研究仍然是一个迫切需要。我们通过报告户外、学科内设计寻路研究的结果来解决这一研究空白（$ñ=52$）。参与者走了两条不同的路线，他们要求根据这些路线进行口头的、基于地标的转弯路线指示。通过生存分析，我们对参与者发出此类请求的空间点进行建模，同时考虑个人、环境、路线和试验相关变量。我们揭示了不同的土地覆盖类别（例如，密集的建筑区域）和个人变量（例如，以自我为中心的方向和年龄）是重要的，讨论了它们影响的潜在原因并得出了开放的研究问题。
