The effect of volumetric (3D) tactile symbols within inclusive tactile maps
We compare two tactile maps, one of them includes Volumetric (3D) tactile symbols. Improving the interaction between users and tactile maps using 3D symbols together with 2D ones. 3D symbols can be located in less time and, generally, cause fewer errors than flat relief symbols-2D. 3D printing opens new horizons for the design and production of tactile maps for blind users.
