BlipBla Mobile and Collaborative App to Teach Lip Reading to Children Who Are Deaf

UNESCO emphasizes the need for inclusive and quality education for all. In this context, the present article introduces BlipBla, a mobile and collaborative application designed to teach lip reading to preschool-aged deaf children. The development of BlipBla integrates active pedagogical methodologies, mobile technologies, and an accessible interface that facilitates interaction between teachers and students without requiring advanced reading and writing skills. The main contributions of this work include: 1) the design of an educational tool that incorporates vocabulary and sentences with clear grammatical structure; 2) the implementation of a customizable and collaborative environment; and 3) the validation of the application based on the ISO 25010 standard, which reported functional compliance above 94% in both the administrator and student environments. It is concluded that BlipBla represents a significant advancement in the development of accessible resources tailored to the needs of the deaf child community, and further testing with end users is projected to strengthen its usability and educational reach.
