The Co-design method has great relevance in the inclusion of different classes of users in the Design Process (DP), such as Visually Impaired People (PwDS) and children. This work indicates results of three Co-design dynamics. Focus Group, guided tour, semi-structured interviews, questionnaires and workshops were carried out, as strategies for the inclusion of different users in the DP. The process of designing an inclusive signage board for PwDS is presented. Next, the project of inclusive playgrounds for visually impaired children. Finally, an activity carried out with basic education students, combining new technologies in the child's learning process. Participants were encouraged to express their knowledge through different tools that adapted to their reality. The results show the importance of including different methods, tools and resources to support the DP. In addition, Digital Fabrication and Prototyping are techniques that enhance Co-design, as they act as congratulators for communication between the designer and users.
