Mapeamento sistemático, Documentos de patente, Deficientes visuais, Leitura de imagens


With the advent of the industrial revolution, several technological innovations emerged, aiming to solve some problems in a society's daily life. This paper aims to carry out systematic mapping of the state of the art in patent documents to identify the technologies developed for reading images' descriptions aimed at visually impaired citizens. During the mapping, we found 491 primary studies that passed through filters (inclusion, exclusion criteria, and quality issues), in which we could extract 46 relevant patent documents. Of these 46 documents, we observed that there is still few participation by the academic community in patenting their inventions and that 6% of these documents can be located in periodical libraries.
