This article presents the development of product requirements in the context of an assistive technology innovation project. It is emphasized that assistive technology plays a fundamental role in the development of sustainable products and environments, as it enables the inclusion and autonomy of people with disabilities, ensuring that all solutions are accessible and efficient. The initial stages of new product development are considered critical due to the need to define requirements that will guide the design process. The challenge in formulating these requirements lies in the contradiction between determining which criteria and factors should accompany the project at a stage where the understanding of the object and the problem is still limited. The methodological approach is primarily based on a descriptive method of the design process leading to the definition of requirements. The results are mainly divided into four topics: project description, description of the stakeholders and actors involved in the project, description of the process of defining design requirements, and finally, the presentation of the requirements developed in the project context. These results can contribute to two main ways: by sharing the defined requirements and by presenting a process of collective construction of design requirements.
