In the world, there are millions of children with severe visual or auditory disabilities, who face particular difficulties in the development of their spatial and sensory skills during the first years of their growth and their inclusion in school life. The development of rehabilitation devices adapted to a person's needs is an opportunity to improve the educational experience in biomedical design courses, and to work in collaboration with specialized institutions. In this article we present the design and development of an interactive mat for didactic purposes, which allows blind or deaf children to perform activities that improve their spatial capacity, has visual, sonorous and haptics features that promote their sensory development, and serve as a general-purpose input peripheral for the computer, which makes it possible for children to interact through it with a lot of games and applications currently available.
