    Desenvolvimento de um dispositivo vestível de assistência à locomoção utilizando visão computacional e internet das coisas
    (INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2026-02-27) Pereira, Guilherme Barbosa; Silva, Cledja Karina Rolim da; http://lattes.cnpq.br/1770216488772332; Silva, Cledja Karina Rolim da; http://lattes.cnpq.br/1770216488772332; Souza, Tarsis Marinho de; http://lattes.cnpq.br/9808563385937929; Tenório, Fernando Antonio Guimarães; http://lattes.cnpq.br/0678507623542382
    Autonomous urban mobility is an essential aspect of the quality of life for visually impaired individuals, who often face physical and architectural barriers aggravated by the lack of accessibility in cities. Traditional tools, such as the white cane, although fundamental, have limitations in detecting aerial obstacles and in the semantic identification of the environment. Given this scenario, this work proposes the development of a wearable visual assistance system based on the Internet of Things (IoT) and Artificial Intelligence. The solution applies Computer Vision technology as a way to understand the environment. The Image capture and distance measurement are performed by an ESP32-CAM module, while heavy processing and inference occur on an external server. The main innovation lies in the feedback delivery: the server processes the image and sends the synthesized audio alert (Text-to-Speech) in real-time via the WebSocket protocol to an Android mobile application, which instantly reproduces the message through the user's headphones. To validate the proposal, tests were performed that could identify objects and report their distance with low latency. The results demonstrate that the integration between IoT, cloud processing, and mobile devices contributes significantly to increasing safety, contextual perception, and locomotion independence for the visually impaired.

    Marvin: um chatbot para auxílio à comunidade do IFAL
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-12-22) Leandro, Jonas Sousa; Silva, Cledja Karina Rolim da; Menezes, Douglas; Souza, Tarsis Marinho de
    The huge amount of data aggravates the search for information, because most of the data are texts, unstructured and dispersed in several sources. In this context, this work aims the use and the development of a chatbot to improve the user experience related to IFAL campus Arapiraca. This study describes a peer-review of similar work, the development of an application, and the user testing. To the development of the chatbot, it was called Marvin, it carried out the reading of pedagogical projects, normative instructions, and internet pages, besides the study of the frameworks related to chatbots. The user testing had the goal to evaluate the using and acceptance of the chatbot. And in agreement of the data results, Marvin has had a good acceptance, being an interesting solution to the information access.

    Trabalhando o pensamento computacional em alunos com deficiência visual
    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-12-15) Silva, Miguel Márcio Magalhães; Silva, Cledja Karina Rolim da; http://lattes.cnpq.br/1770216488772332; Silva, Cledja Karina Rolim da; http://lattes.cnpq.br/1770216488772332; Barbosa, Anderson Felinto; http://lattes.cnpq.br/5590648222014479; Ferreira, Diogo Sarmento; http://lattes.cnpq.br/6673430404078107
    This project focuses on applying computational thinking and programming logic to individuals with visual impairments, aiming to develop an accessible learning application. Using pre-developed 3D physical blocks and QR codes, the application provides an accessible and interactive interface, allowing users to construct algorithms tangibly and step-by-step. All of this aligns with web accessibility guidelines, providing an adapted experience for mobile devices and screen readers. Following implementation, a detailed evaluation was conducted to assess the tool's effectiveness. This work highlights the results of this assessment, along with the lessons learned during development. The emphasis lies in the practical applicability of the tool in teaching programming logic to individuals with visual impairments, with the goal of providing an accessible and effective learning experience. The results demonstrated that the tool brings significant benefits to programming learning for individuals with visual impairments, not only ensuring their inclusion but also enhancing the overall quality of education.
