Thematic maps are used in education and the lack of such materials makes it difficult to fulfill particular subjects’ curriculums. In this research, we propose a methodology for automatic compilation of legible and cartographically sound educational thematic tactile maps that bases on the concept of anchor layers and uses unequivocal parameters for generalization operators. Using such an approach we were able to automate the most complicated parts of the procedure that deal particularly with the generalization of geospatial data. We verify the proposed methodology by preparing a sample case study 3D printed map that is later evaluated by students with visual impairments. We also evaluate a novel approach of hybrid map production that consists of both graphic and tactile content. Our results suggest that the proposed methodology can be used for fast and repeatable production of fully fledged thematic tactile maps and that it forms a significant step toward completely automatic tactile maps development in the future.

This task is encountered every day, sometimes incorrect reading of traffic signs can lead to very serious results. In particular, the Arabic language is very difficult, making recognizing and viewing Arabic text a difficult task. In this context, we are looking for an effective solution to remove errors and results that can sometimes end someone's life. This article aims to correctly read traffic signs with Arabic text using augmented reality technology. Our system is composed of three modules. The first is text detection and recognition. The second is Text visualization. The third is Text to speech methods conversion. With this system, the user can have two different results. The first result is visual with much-improved text and enhancement. The second result is sound, he can hear the text aloud. This system is very applicable and effective for daily life. To assess the effectiveness of our work, we offer a survey to a group of visually impaired people to give their opinion on the use of our application. The results have been good for most people.

Perspectives about implementation of colour codes on maps accessible to blind people / Niédja Sodré de Araújo in International journal of cartography, vol 8 n° 1 (March 2022)  

Public [article]  inInternational journal of cartography > vol 8 n° 1 (March 2022) . - pp 133 - 147 Titre : Perspectives about implementation of colour codes on maps accessible to blind people Type de document : Article/Communication Auteurs : Niédja Sodré de Araújo, Auteur ; Luciene Stamato Delazari, Auteur ; Amanda Pereira Antunes, Auteur ; Andrea Faria Andrade, Auteur Année de publication : 2022 Article en page(s) : pp 133 - 147 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Rédaction cartographique [Termes IGN] carte tactile [Termes IGN] couleur imprimée [Termes IGN] personne malvoyante Résumé : (auteur) Tactile colour codes or tactile symbols were developed for communicating colours to blind people. Initially, these colour codes were designed to enable blind or visually impaired people to choose their own clothes and learn colour theory. The objective of this research is to investigate the perspectives of geoinformation professionals on the viability of implementing colour codes on thematic tactile maps using only the graphic primitive area. Thus, geoinformation professionals were invited to express their perspectives on ten colour code systems during and after the “I Workshop Usability 4 All”, which took place during the “XI Brazilian Colloquium on Geodetic Sciences”, Brazil, 2020. The results indicated that there is no consensus on which system is more appropriate for experimentation on tactile maps. However, Feelipa Color and See Color were the systems that showed the greatest potential as six participants preferred the first and five preferred the latter. This is associated with the fact that both systems were classified as relatively viable or potentially viable for implementation in the primitive area, considering the aspects of Drawing, Dimensions and Intuitiveness.

An experiment using the graphic variable color and the see color code on isarithmic maps accessible to blind and normally sighted people / Niédja Sodré de Araújo in Boletim de Ciências Geodésicas, vol 27 n° 1 ([01/03/2021])  

Public [article]  inBoletim de Ciências Geodésicas > vol 27 n° 1 [01/03/2021] Titre : An experiment using the graphic variable color and the see color code on isarithmic maps accessible to blind and normally sighted people Type de document : Article/Communication Auteurs : Niédja Sodré de Araújo, Auteur ; Fabricio Rosa Amorim, Auteur ; et al., Auteur Année de publication : 2021 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] carte tactile [Termes IGN] cognition [Termes IGN] couleur (rédaction cartographique) [Termes IGN] personne malvoyante [Termes IGN] variable visuelle [Vedettes matières IGN] Cartologie Résumé : (auteur) The See Color is a color coding system based on Braille writing to communicate colors to people with visual impairments. This study assessed the perception of the theme Temperature by blind people, by using the See Color code on two isarithmic tactile maps and the perception of subjects with normal color vision. An average temperature map of Australia had 10 classes, but these intervals were regrouped into four classes on Corel Draw software. The new map was duplicated in the digital project in A4 size, both included the See Color code in two color schemes obtained from the Color Brewer website. Subsequently, they were laser-printed on swell paper to produce the tactile relief. The chromatic perception was observed, as well as the thermal sensations that the colors could represent for blind participants (06), normally sighted participants in basic education (23), and normally sighted participants in higher education (20). In this research, the See Color code showed the potential to provide spatial knowledge as a graphic language through colors in color maps for adventitiously blind and for normally sighted participants based on their perception of colors and tactile color codes.
