“…While possible in a research setting, this approach could be a barrier to adoption of the technology by practitioners. As an alternative, symbols could be designed in a GIS program (Voženílek & Vondráková, 2014), which would more closely reflect a typical cartographic work flow, or could be automated using web-based tools (Taylor et al, 2015).…”

Introduction Technological advances have introduced three-dimensional (3-D) printing as an option for creating tactile maps for people with visual impairments (that is, those who are blind or have low vision), diversifying the types of map products that are available. At the same time, it presents a challenge to map makers to implement designs across multiple production methods. We evaluated map symbols to determine their discriminability across three different materials: microcapsule paper, 3-D printer plastic, and embossed paper. Methods In a single session lasting less than 90 minutes, participants completed a matching task and provided informal feedback regarding their preferences. We measured speed and accuracy to establish discriminability of map symbols on each of the materials. Eighteen participants were recruited from a referred sample among attendees at the American Council of the Blind annual convention in 2013. Results Response times were significantly different across the three materials (p < 0.001). Without sacrificing accuracy, response times were faster for the 3-D printed graphics than for either the microcapsule paper (p < 0.001) or the embossed paper (p < 0.001). User preference was divided across the three materials. Some people disliked the “sharp” corners of the 3-D printed symbols, while others preferred their “crisp” edges. Discussion Our results demonstrate faster discriminability of a set of tactile symbols produced on a 3-D printer compared to those same symbols printed on microcapsule paper, the material for which the symbols were originally designed. Participant feedback reflected preferences both in favor of and against reading symbols produced on the 3-D printer. Implications for practitioners This article discusses the functional equivalence of tactile symbols produced across multiple production technologies. It addresses two considerations when using 3-D printing to make tactile maps: preparing digital files for printing and the printing work flow. Digital files ready for printing on each of the three materials are available for download (Brittell, Lobben, & Lawrence 2016).

“…Within the project, mainly large-scale plans of specific localities were created. One of the important aspects are technological limits for 3D printing (Voženílek, Vondráková, 2014). Due to the fact that the requirement was the creation of relief maps of very small sites, where commonly available data sets are not sufficient to implement such a scale, the method of non-automated computer 3D modeling was chosen.…”

The Development of mental model of people with visual impairment in spatially-orientational and cultural-historical context, is longer Title of the Post. The ability to create mental models is, for people with visual impairment, one of the basic preconditions for the use of available information from the environment and in all areas of everyday life. Tactile graphics can provide one of the means for the development of imagination; they are particularly suitable for the creation of a complex picture of a given situation and its processing into supporting information. Their facilitating function in the development, refinement and consolidation of the imagination is indisputable and proven by empirical studies. The purpose of this paper is to present the application possibilities of three-dimensional displays of haptic information for the purposes of spatial orientation, as well as access to cultural and historical objects with emphasis on the formation of mutual relations and connections within the knowledge base of each individual with visual impairment.

“…A tecnologia para impressão tridimensional (3D) foi uma nova opção que surgiu nos anos recentes, permitindo, assim, a diversificação dos mapas táteis, mas também se apresentando como um desafio para os pesquisadores, que iniciaram investigações sobre tipos de símbolos, tamanhos adequados para impressão (figura 3), tempo de produção, facilidade de reconhecimento via tato, entre outros (VOŽENÍLEK, VONDRÁKOVÁ, 2014, ORTÍ; CAZORLA; MACIA, 2015, BRITTEL; LOBBEN; LAWRENCE, 2018). A tecnologia da impressão 3D foi utilizada também em mapas com recursos sonoros por pesquisadores como Voženílek et. al (2009) e Voženílek e Vondráková (2014).…”

Neste artigo de revisão apresenta-se o estado da arte da Cartografia Tátil a partir de seus avanços e desafios. Primeiro, mostra-se o recorte histórico em nível internacional e nacional com ênfase nas publicações datadas dos séculos XX e XXI. Depois, discorre-se sobre o aporte teórico e metodológico que indica a propensão de se tratar os temas Geografia e Cartografia na Educação a partir de investigações que têm como base principal as teorias de Piaget ou Vigotski. Como desafios de pesquisas a serem enfrentados, elencam-se a padronização da linguagem Cartográfica Tátil, consenso na produção e impressão de mapas táteis, mas, principalmente, a metodologia para o ensino do mapa para alunos cegos. As discussões finais, que direcionam a indicação das contribuições, são pautadas em experiências com alunos cegos e mostram a importância da iniciação cartográfica da criança cega a partir da sua iniciação ao desenho, ainda na fase pré-escolar, com a mediação de linguagens e exploração do ambiente próximo, tendo como referencial seu próprio corpo.
