TORRES, Josiane Pereira; COSTA, Carolina Severino Lopes da  e  LOURENCO, Gerusa Ferreira. Visuo-Tactile and Visual-Auditory Sensory Substitution in People with Visual Impairment: a Systematic Review. Rev. bras. educ. espec. [online]. 2016, vol.22, n.4, pp.605-618. ISSN 1980-5470.  https://doi.org/10.1590/S1413-65382216000400010.

In an attempt to acknowledge the scientific literature on sensory substitution, the aim of this study was to analyze the methods and devices for sensory substitution for visually impaired people presented in empirical research in scientific articles. This is a systematic review of the literature whose source of data were articles published in online journals in Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, in Portuguese and English in the last five years. The keywords were: sensory substitution, visuo-tactile substitution, visuo-auditory sensory substitution and their matches in Portuguese. The searches retrieved a total of 186 articles. After the selection from reading the titles and the abstracts, the corpus consisted of 11 articles which were considered for the final sample. The review only reported international articles. Some methods and sensory substitution devices were identified; most research proposed evaluating these devices in situations of navigating in different spaces, and identifying barriers and obstacles in the environment. Except for one article, the others carried out their research in ideal laboratory conditions. The results of the studies are mostly quantitative in which the perceptions of visually impaired users are not considered, however, the focus is directed to validate the efficiency of the sensory substitution devices. We considered that it is necessary to deepen the research in the area covering other sources such as theses and dissertations. The need for investment is also emphasized in studies of this type of resource to favor the access for visually impaired population.
