However, conventional interactions still present barriers for people with disabilities, as they do not fully meet accessibility demands. One example of this is the need to use hands to interact with a television, which can make the system inaccessible to a portion of society with motor impairments in their hands and arms. Even though the market offers the possibility of voice commands, this option still requires button activation and does not satisfactorily provide users with motor limitations the autonomy to operate the device smoothly and with minimal difficulty. Furthermore, existing studies that focus on developing alternatives to conventional remote controls either use intermediary tools, such as smartphones, to process commands or are focused on the convenience of non-disabled users, rather than on accessibility. In this context, the aim of this work is to develop an intuitive and low-cost prototype capable of helping people with different degrees of motor impairment in the upper limbs to control a television solely through head gestures and breath, by remotely sending commands via infrared light. A quality and usability test was conducted with volunteers to evaluate the system, which received positive feedback from users, despite some difficulties reported in activating the device by breath and in the specific task of turning the television on, which corresponds to the upward head movement. It is important to highlight that all resources and tools used during the development were free and open-source.Acesso AbertoAcessibilidadecontrole por gestoslimitações motorasAccessibilitygesture controlmotor impairmentsCNPQ::ENGENHARIAS::ENGENHARIA ELETRICATrabalho de Curso - Graduação - Monografia
