In-Car Navigation System and Route Guidance (RGNS), commercial or free, have adopted different graphic designs to maps which support the navigation task. This paper aims at evaluating the driver's subjective preference for colors to represent route and arrow direction in maps for these systems. A total of 54 drivers (27 males and 27 females) participated in an experiment which was performed in a parked vehicle. Two cartographic representations were produced to evaluate the route color and other two for the arrow color. The route was symbolized by black or blue color and the arrow direction by green or red hue. The cartographic representations were presented in a seven-inch navigation monitor. The results indicate that most drivers prefer the navigation route in black color. However, drivers who regularly use navigation systems have presented the tendency to prefer the route in blue hue. The direction arrow in green hue was the mostly preferred by the drivers and there was no significant correlation between different individual characteristics. This study concludes that drivers' preference was influenced by different factors, such as grouping by color, shape and proximity, subjective or conventional association, as well as by the level of contrast among the map features. Evaluating the performance of cartographic representations in route following task is recommended, in order to support the influence of graphic designs to maps in usability of route guidance systems.

In this article, we aim to describe and explain what is the model “practical group of displacements”, introduced in 1937 by Piaget’s work La construction du reel chez l’enfant (Neuchâtel, Paris: Delachaux et Niestlé), essential to comprehension of the construction of space. To this end, we introduce the mathematical notation to describe it, we give the meaning of this notation in the child’s behavior and explains the mathematical structure of group underlying the model.
