Identification of Properties and Morphological Characteristics in Tactile Textures: a Study on Educational Graphics and Cartographies for Visual Impaired Children. Rev. bras. educ. espec.

This article explores the textures that have been used in the development of thematic maps and images for children with visual impairment in Chile over the last 20 years. From a representative group of more than 300 sheets of inclusive educational content, 14 textures were selected to identify their nature, psychophysical properties and morphological characteristics based on their geometric composition. The aim was to generate the theoretical and technological grounds related to the design and digital production of tactile maps, images, and graphics. The work sought to typify the embossed shapes and their possible applications by using repetition patterns that allow to improve the language and recognition of the textures involved, with the intention of expanding and diversifying their use in inclusive educational material in the teaching and dissemination of knowledge through tact.

Keywords : Inclusive education; Tactile texture; Visual impairment; Images; Haptic perception.
