ABSTRACT
Tactile colour codes or tactile symbols were developed for communicating colours to blind people. Initially, these colour codes were designed to enable blind or visually impaired people to choose their own clothes and learn colour theory. The objective of this research is to investigate the perspectives of geoinformation professionals on the viability of implementing colour codes on thematic tactile maps using only the graphic primitive area. Thus, geoinformation professionals were invited to express their perspectives on ten colour code systems during and after the “I Workshop Usability 4 All”, which took place during the “XI Brazilian Colloquium on Geodetic Sciences”, Brazil, 2020. The results indicated that there is no consensus on which system is more appropriate for experimentation on tactile maps. However, Feelipa Color and See Color were the systems that showed the greatest potential as six participants preferred the first and five preferred the latter. This is associated with the fact that both systems were classified as relatively viable or potentially viable for implementation in the primitive area, considering the aspects of Drawing, Dimensions and Intuitiveness.
ABSTRAITE
Les codes des couleurs tactiles ou les symboles tactiles ont été développés pour communiquer la couleur aux non-voyants. Au début, ces codes de couleurs ont été conçus pour permettre aux non ou mal voyants de choisir leurs propres vêtements et apprendre la théorie des couleurs. L'objectif de cette recherche est d'étudier les perspectives, pour les professionnels de l'information géographique, pour implémenter les codes couleurs sur les cartes tactiles thématiques en utilisant uniquement les objets surfaciques. Ainsi, des professionnels de l'information géographique ont été invités à exprimer leurs points de vue sur 10 systèmes de code de couleur pendant et après le workshop intitulé ‘Ergonomie pour tous' qui a eu lieu pendant le 11ème colloque Brésilien des Sciences Géodésiques au Brésil en 2020. Les résultats montrent qu'il n'y a pas de consensus sur le fait qu'un système soit plus adapté qu'un autre pour l'expérimentation de cartes tactiles. Pourtant, les système Feelipa Color et See Color ont montré un plus grand potentiel puisque six des participants ont préféré le premier et cinq le deuxième. Par ailleurs, les deux systèmes ont été classés comme viables ou possiblement viables pour l'implémentation sur les objets surfaciques, en prenant en compte les critères de dessin, de dimension et d’intuition.
