Desenvolvimento de um leitor de tela para deficientes visuais no sistema operacional Android Crateús 2023

Abstract

It is quite noticeable that the use of mobile devices has grown substantially in recent years, mainly due to the evolution of hardware and software. In this sense, daily activities have been fully or partially adapted to smartphones, and these activities are carried out through applications, which have grown in quantity as much as smartphones. Mobile solutions are used for simple tasks such as medication reminders, watching videos, and listening to music. In addition, the use of mobile devices for entertainment, such as games and paid content platforms, has also gained prominence. However, there are uses in more complex and delicate operations, such as payments and bank transfers, or even solutions related to people monitoring through platforms that use sensors. Despite this popularization, not all applications are accessible, and to address these issues, accessibility technologies have emerged. However, users with visual impairments face issues when using these tools, such as verbosity of reading, awareness, and location within applications. In addition, some tools present numerous problems, resulting in non-usage or only basic functionalities being employed, such as text-to-speech, which can be inserted without necessarily creating an implementation. This work focuses on developing an assisted reading tool for the Android operating system, focusing on issues found in the literature and interviews. It was analyzed regarding the Verbosity of Information, Text Input, Copy and Paste, and Feedback in Text Boxes, and it was possible to conclude that any functionality should be added with maximum customization and configurability without hindering the autonomy and usability of the application, i.e., not adding mandatory options, always allowing the user to choose what they want to use and when.
