The aim of this article is to determine whether the process of memorizing a tactile map key, or legend, can be improved by including three-dimensional (3D) symbols produced by means of 3D Printing. The method used in this study involved asking a group of 20 volunteers with different profiles to memorize eight tactile symbols from two keys, each of which had different characteristics: Key 2 included 3D tactile symbols and Key 1 had only two-dimensional (2D) tactile symbols. Results show statistically significant differences between the two keys. Use of Key 2 yielded a 48.72% reduction in the number of errors compared to Key 1 (N = 20, p-value = .014). These data show that combining 3D with flat relief symbols (2D) improves the process of memorizing a tactile key because the 3D attributes can be distinguished from the 2D features by touch. For practitioners, this article provides data about the possibilities of 3D Printing applied to tactile maps, keys, and symbols. [-]

Improving Tactile Map Usability through 3D Printing Techniques: An Experiment with New Tactile Symbols
Gual, Jaume; Puyuelo Cazorla, Marina; Lloveras Macià, Joaquim Maney Publishing (2013-12-05)This paper shows an experiment with tactile maps designed for visually impaired persons. Tests were carried out on a tactile map produced with 3D printing and including a new type of tactile symbols, volumetric symbols ... -
The effect of volumetric (3D) tactile symbols within inclusive tactile maps
Gual, Jaume; Puyuelo Cazorla, Marina; Lloveras Macià, Joaquín Elsevier (2015-05)Point, linear and areal elements, which are two-dimensional and of a graphic nature, are the morphological elements employed when designing tactile maps and symbols for visually impaired users. However, beyond the ... -
Model of tactile sensors using soft contacts and its application in robot grasping simulation
Moisio, Sami; León Pinzón, Beatriz Elena; Korkealaakso, Pasi; Morales, Antonio Elsevier (2013-01)In the context of robot grasping and manipulation, realistic dynamic simulation requires accurate modeling of contacts between bodies and, in a practical level, accurate simulation of touch sensors. This paper addresses ...
