Abstract
Linking perception to decision point complexity for adaptive indoor wayfinding support
Highlights
This adaptation can be implemented in several components of a wayfinding system
Several methodologies are developed to this end and some of them have been proven to correlate well with wayfinding strategies of navigators, such as isovists and the space syntax theory
An isovist is the area in space which can be seen from a certain viewpoint. This isovist area can be drawn on a floorplan of a building, resulting in a polygon with several geometric properties that can be used to quantify the complexity in a certain point of a building
Summary
This adaptation can be implemented in several components of a wayfinding system (e.g. the route planning by generating the least turn path instead of the shortest path). In complex buildings, wayfinding can be challenging and induce a rise in cognitive load. Indoor wayfinding aids have to be adapted to both the architecture of the building and the requirements of the users. First of all, the complexity of a building has to be quantified.
