Orientador: Francisco Márcio Barbosa. 2025. 10 f. Monografia (graduação) - Universidade Federal do Rio Grande do Norte, Centro de Ensino Superior do Seridó, Bacharelado em Sistemas de Informação, Caicó, RN, 2025.https://repositorio.ufrn.br/handle/123456789/63774This paper presents the development of a low-cost Bluetooth headmouse aimed at assisting individuals with motor disabilities in interacting with computer devices. The proposal seeks to offer an affordable alternative within the field of assistive technology, promoting greater digital inclusion. The device is composed of MPU-6050, TTP223, and TCRT5000 sensors, integrated with an ESP32 microcontroller responsible for transmitting commands via Bluetooth Low Energy (BLE). With an estimated cost of approximately R$ 100, the project stands as a viable alternative to commercial solutions such as the VOA Colibri by Tix, priced at around R$ 3,000, and the Origin HeadMouse Nano by Tobii Dynavox, which costs US$ 995. While these devices are effective, their high prices limit accessibility for a large portion of the population. In this context, the project aims to democratize this technology by offering a functional and economically accessible solution capable of providing greater autonomy and promoting digital inclusion.pt-BRAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Tecnologia AssistivaAcessibilidade DigitalHeadmouseMicrocontrolador ESP32.Assistive TechnologyDigital AccessibilityESP32 MicrocontrollerbachelorThesisCIENCIAS EXATAS E DA TERRA
