Purpose: to present a new application for mobile devices, referred to as Desembaralhando, for intervention in the problem of dyslexic children mirror writring. Methods: the development of the application is the result of a set of clinical and speech therapy information and experiences, which points out frequency of letter mirroring as a challenging problem in children with dyslexia. The application, developed in the light of the multisensory approach, was created by a multidisciplinary team of computer scientists, a game designer and a speech therapist, in order to meet users requirements, such as appropriate fonts and colors. Results: the activities stimulate phonological awareness skills from the association between images and words, audio aids, as well as an original function that is the rotational movement of letters b/d and a/e, which facilitates the perception of the visual layout of the letters. Conclusions: guidelines such as the choice of typography and interface colors appropriate to dyslexic children are used to favor intervention, in order to minimize the difficulties of these children regarding letters mirroring.

This paper aimed at reviewing the literature related to national and international research on spelling difficulties by dyslexics and identifying the intervention approaches performed with regard to this topic. An integrative review of the literature was carried out in order to answer the question: considering the domain of the orthography, one of the challenges frequently faced by dyslexics, how are studies on the relationship between dyslexia and spelling characterized? The research was carried out in PubMed platform, Scopus database and Portal de Periódicos CAPES/MEC. To search the articles, the following descriptors were used: "dislexia" or "dyslexia" with the free terms "ortografia" or "spelling". One aspect should be highlighted: some works indicate that difficulties in the spelling performance by dyslexics are not exclusively due to phonological processing failures -they are also secondary to alterations in orthographic processing. A challenge faced by dyslexics is to retain phonological information to use in writing new orthographic forms. Researchers suggest that intervention strategies include phonological, orthographic and lexical activities. It is observed that few studies have analyzed the difficulties that dyslexics face when dealing with new words, as well as writing, correctly, frequently used words in their own language.

The current paper aims to present an integrative literature review of scientific articles published in national and international journals, approaching the use of information and communication technology (ICT) such as computers, tablets, iPad's, mobile phones, e-readers, virtual reality and virtual learning environments, applied to dyslexia. The database consists of scientific articles published between 2010 and 2015, from the following platforms: Science Direct/Elsevier, SciELO -Scientific Electronic Library Online, MedLine -Medical Literature Analysis and Retrieval and Portal de Periódicos da CAPES. Scientific articles were selected, corresponding to 20 international (95.23%) papers and 1 national (4.77%) paper. The works considered in the present paper in general aim at the development and application of technological instruments that can minimize the difficulties by dyslexics in reading and writing learning. Due to shortage of articles published in Brazil, there is a need for more studies on this topic in view of the benefits of ICT within evaluation and intervention in dyslexia observed in international articles. Keywords: Dyslexia; Technology; Software RESUMO O objetivo deste estudo é apresentar uma revisão integrativa da literatura, contemplando artigos científi-cos publicados em periódicos nacionais e internacionais que abordam o uso das tecnologias da informação e da comunicação (TIC), tais como computador, tablets, iPads, mobile phones, e-readers, realidade virtual e ambiente virtual de aprendizagem, aplicadas à dislexia. A base de dados escolhida para este estudo foi constituída de artigos científicos publicados no período de 2010 a 2015, a partir das seguintes bases eletrônicas de dados: Science Direct/Elsevier, SciELO -Scientific Electronic Library Online, MedLine -Medical Literature Analysis and Retrieval e o Portal de Periódicos da CAPES. Foram selecionados para este estudo 21 artigos científicos, sendo 20 (95,23%) artigos internacionais e um (4,77%) artigo nacional. Os trabalhos contemplados, no presente estudo, em geral, visam a construção e aplicação de instrumentos tecnológicos que possam vir a minimizar as dificuldades do disléxico no âmbito da aprendizagem da leitura e da escrita. Em meio à escassez de artigos publicados no Brasil, verifica-se a necessidade de mais estudos sobre essa temática, tendo em vista os benefícios das TIC no âmbito da avaliação e intervenção em dislexia constatados em artigos internacionais.

Abstract. This paper presents a crossword game application for smartphone devices, which aims to stimulate the visual memory of words with phonological awareness of dyslexic children. The application also aims to collect user data in order to generate application usage statistics, and can report, for example, the higher error frequency words. Information obtained through the application of questionnaires for speech-language pathologists points out the originality and adequacy of the application.Resumo. Neste artigo é apresentado um aplicativo do jogo de palavras cruzadas para dispositivos smartphones, que tem como objetivo o estímulo à memória visual das palavras, associada à consciência fonológica de crianças disléxicas. O aplicativo também apresenta como objetivo a coleta de dados dos usuários, com o intuito de gerar estatísticas de uso da aplicação, podendo informar, por exemplo, as palavras que possuem uma maior frequência de erros. Informações obtidas por meio de questionários aplicados a fonoaudiólogos apontam para a originalidade e adequação do aplicativo.
