Little research has studied how those factors are experienced by people wayfinding in the real environment.
In this framework, the present paper has analyzed the effect of rotation for wayfinding in navigating multi-level buildings.
In Lawton's theory (Lawton 1996), there are two main strategies for wayfinding in indoor environments—orientation strategy and route strategy.
We conducted an experiment on wayfinding in a university hospital consisting of four interconnected buildings, each with 8 to 17 floors.
Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media.
Previous research (Passini 1992) proved that wayfinding in complex environments often causes newcomers and occasionally frequent visitors uncertainty and stress, even with the assistance of wayfinding aids.
Current research seems to pay more attention to wayfinding in two-dimensional environments investigating it in public buildings such as hospitals, airports or university departments, where it is more common to experience disorientation.
Our focus for sensory substitution is wayfinding, in particular, providing medium distance information, up to 10 m, that is beyond the reach of the long white cane while not addressing global positioning GPS.
