No município de Marabá, estado do Pará, a mesma pesquisa censitária informa 25% da população possuindo alguma deficiência. Observando-se essas informações e ressaltando a realização de audiências públicas discutindo os problemas de falta de acessibilidade na cidade, este trabalho fez um estudo acerca da falta de espaços físicos com aparatos de acessibilidade a deficientes físicos, foi utilizado questionário para colher opiniões dos moradores da cidade estudada, utilizou-se a plataforma Android Studio e a linguagem C++ para prototipação do aplicativo. Alcançou-se o objetivo estipulado, a criação de protótipo em dispositivos móveis para mapear locais disponíveis a todos, criando ranking, para elencar quais encontram-se com mecanismos para facilitar o ir e vir de pessoas caracterizadas como PCD. Verifica-se como resultado além da criação do app a necessidade de demais trabalhos e outros softwares com objetivos semelhantes na língua portuguesa e brasileiro.

Prototype application for mobile devices for mapping environments with architectural accessibility: a case study in the city of Marabá-PA AbstractData from the last Brazilian census show 23.9% of the population self-reported "Person with Disability -PCD". In the municipality of Marabá, state of Pará, the same census survey reports 25% of the population with some disability. Observing this information and emphasizing the holding of public hearings discussing the problems of lack of accessibility in the city, this study made a study about the lack of physical spaces with accessibility devices for disabled people, a questionnaire was used to gather opinions of residents of the city. city, the Android Studio platform and the C ++ language were used for prototyping the application. The stipulated goal was to create a prototype in mobile devices to map available places to all, creating ranking, to list which are with mechanisms to facilitate the coming and go of people characterized as PCD. As a result, besides the creation of the app, there is a need for other works and other software with similar objectives in the Portuguese and Brazilian languages.
This proposal is a suggestion to the Brazilian Association of Technical Standards (ABNT), in NBR 15290, over accessibility Digital TV. The focus is to discuss and establish a standard navigation scheme to accessible NCL applications to be annexed to NBR 15290. This navigation scheme can be used as guidelines for developers to create NCL applications for people with a visual or hearing disability.
In the context of interactive digital TV applications (iDTV), mental models can be especially useful to represent the cognitive structure of users during learning these applications. These models help to highlight which elements (e.g. behavioral and spatial) are perceived by users, thus contributing to a proper understanding and use of learning objects, created for iDTV environment through metacommunication between developers and users. The results of this study show that the use of metaphors as storyboard and natural language are recurrent among users and that the elements of an interactive narrative for iDTV are not yet fully understood by beginners users. Resumo.No contexto de aplicativos TV Digital interativa (TVDi), modelos mentais podem ser especialmente úteis para representar a estrutura cognitiva de usuários durante o aprendizado desses aplicativos. Tais modelos ajudam a destacar que elementos (e.g. comportamentais e espaciais) são percebidos pelos usuários contribuindo, assim, para uma adequada compreensão e uso de Objetos de Aprendizagem, criados para o ambiente TVDi, por meio da metacomunicação entre desenvolvedores e usuários. Os resultados deste estudo revelam que o uso de metáforas como storyboard e linguagem natural são recorrentes entre os usuários e que os elementos de uma narrativa interativa para TVDi ainda não são plenamente compreendidos por usuários iniciantes.
People with visual impairments suffer from the incapacity to understand contextual information in videos, such as the place where characters are, or any other non-spoken actions in general. Some content creators address this issue by providing a secondary audio to describe such information, called Audio Descriptions (ADs). How- ever, some works in the literature have highlighted that people with visual impairment are usually not able to completely understand scene changes based only on characters’ voices or traditional ADs. Moreover, traditional ADs do not completely describe some of the important visual information, such as the background scenery (e.g. colors, furniture) and characters’ details (e.g. blond woman using a red dress). In this work, we propose incrementing the traditional AD techniques with the usage of interactive video features present in TV systems. More precisely, the proposed interactivity enables users to access specialized AD for different visual information (e.g., scene, scenario, character). To support the development of such interactive content, we present an application template, which helps to create the final interactive-enhanced video application. Asa proof of concept for our approach, we created an interactive AD for an independent video mainly composed of visual information, with only a few talks.
