Especificaciones para el diseño de gráficos tangibles cerámicos para uso colectivo e inclusivo

Abstract

Ceramic tile "Kersigns" is a new and recent type of inclusive tactile graphics adapted to people with visual impairment. These tactile graphics are obtained using a novel manufacturing system based on the use of materials, techniques and knowledge typical of the ceramic industry. These graphics have excellent properties for use as fixed tactile graphics for both indoor and outdoor environment use, although they have limitations to reproduce distinct heights and a great diversity of textures. When an inclusive tactile graphic for collective use is designed, it is necessary to consider existing regulations and recommendations regarding geometries to be reproduced and their dimensions, in order that their haptic exploration is appropriate. In addition, these design requirements must include those relating to the technique used to materialize the graphic (machining, casting, etc.). In the proposed work, the most significant design specifications to apply for the development of tactile graphics "Kersigns" are exposed. The work is complemented with a practical application consisting in the development of the tactile graphic that reproduces the campus of Jaume I University of Castellón, in order to improve the inclusion of persons with visual disabilities.
