The services and systems offered by Internet are part of cyberculture s quotidian, but they present several access barriers for the group of people with visual disability. The present research problem involves the accessibility processes of blind users at WWW. The research starts with the presentation of legal regulations that aim at assuring the rights to the access of information and communication for all the citizens and proposes the analysis of elements present on several websites interfaces such as services providers, shopping and governability. What are the communicational elements that can improve navigability s functionality and the interactivity of blind people with cyberspaces? How can accessibility be employed on websites interfaces? Eminent issues such as these ones stimulate the research of interface projects that enable an efficient and satisfactory navigation that considers the fundamental elements for the accessibility of interfaces presented on the web, providing an effective interaction of users with visual disability. Methodologically the research is organized in three steps. For the development of the theoretical basis the bibliographic research was accomplished. The study cases were performed based on semiotic analysis. The empiric research has a qualitative nature and involved data collection, personal narratives and questionnaires. The authors and fundamental theories for the discussion about hypermedia languages and digital medias are Leão and Johnson: for the discussion of communication and cognitive processes we adopted Flusser and Sacks. The study cases analyze constructions of accessible interfaces, with the objective of exploring strenghts and weaknesses in their communicational characters. The fieldwork was composed by three moments. The first one involved a form submission to visually disabled users with the objective of mapping fundamental elements for the navigation with accessibility. The questions planning considered three different levels of interaction: accessibility, usability and the user s experience. In a second moment, it was applied a qualitative research with the recognition of the recommendations extracted from the document dowcag 1.0. The empirical procedure is based on the concept of microssocial scale that proposes an investigation of actors in their interfaces analyzed in the context of a concrete system (Alami). The third phase involved a process of interpretation of the collected data with the objective of developing a model of guidelines that regard the improvement of communication and enhancement of web accessibility. The research concluded that in spite there are documents of recommendation for the accessibility of interfaces, the accessible websites are few
