Evaluation of Assistance Means

We elicited people's conceptualization of turning actions in wayfinding. The theory of wayfinding choremes is based on a seven-direction model (excluding the back-direction) that stems from subjects' sketches of turning situations at intersections. This model has been further refined in an experiment based on the card-sorting paradigm. Here, subjects had to group icons depicting turning situations however they felt it to be appropriate. A cluster analysis lead to the depicted direction model for turning actions.

Currently, we perform a study that compares different kinds of maps in a wayfinding study. This will result in further information with respect to the different maps' performances. We expect to see results in favor of schematic maps.
