- Abstract
- Signage systems are widely used in buildings to provide information for wayfinding, instructions in emergencies, risk location, amongst other things. This paper addresses the visibility of safety signs according to the angle at which they are observed. A theoretical model is developed to explain the relationship of these factors. Experimental trials are performed in order to assess the validity of this model. The experimental findings produced demonstrate a consistency between the theoretical model and the empirical findings. Given this finding, the functionality of the buildingEXODUS model is then extended in accordance with the assumptions on which the theoretical model is based and is then demonstrated using several examples.
