Objectives, Purpose, Or Aim: The aim of this article is to contribute to the better design of wayfinding systems by explicating the indexical properties of directional arrows and their consequences for wayfinding behavior.
Background: The challenges associated with designing for the wayfinding needs of the different groups of users continue to be documented with the poor design of built environments being largely to blame for the wayfinders' inability to navigate complex settings. Directional arrows have been found to be especially problematic in such settings.
Aim: To introduce nurse and healthcare researchers to the ethnomethodological (EM) criteria of the unique adequacy (UA) requirement of methods and to provide guidance on conducting UA research.
Background: Despite the recent shift in emphasis from quantitative to qualitative methods in nursing research, the practice of EM has been largely overlooked.
Data Sources: Published work in EM.
