Three-dimensional tactile images for blind people: A proposition for a translating model of static two-dimensional images

Abstract

This study aims to propose a model to translate static two-dimensional images into three-dimensional tactile images, to be 3D printed, as a way of transmitting information to blind people. The translating model was created from an exploratory method of the literature, which was divided in three steps: 1. Bibliographical review about tactile images, 3D printed tactile images, 3D printing and a search for an analysis model of static two-dimensional images; 2. Tabulation of data found in the bibliographical review and; 3. Model proposition from data crossing. The result is a proposed translating model divided in 4 levels, containing information from recommendations for the creation of tactile images, and a graphic analysis framework.
