Improving wayfinding in hospitals for people with diverse needs and abilities: An exploratory approach based on multi-criteria decision making.

Hospital wayfinding systems that are based solely on signage do not provide adequate solutions for wayfinding needs, especially for users with impairments. Moreover, the interaction between user characteristics and the inner space of the building also determines wayfinding efficiency. The aims of this study, therefore, were to identify architectural features that affect spatial orientation and wayfinding behaviors; demonstrate the implementation of a multi-criteria decision-making (MCDM) approach for improving wayfinding in a diverse range of users; and produce a set of quantitative values (i.
