Key details
Gabriel Sales, a student from the Federal Fluminense University (UFF), has created an innovative application called IA Libras that uses artificial intelligence to translate Brazilian Sign Language (Libras) into spoken and written Portuguese almost in real time. This breakthrough tool addresses significant communication barriers faced by Brazilians with hearing impairments. The app interprets hand movements and body language using common devices like smartphones and computers, making it accessible to a wide population.
Inspired by his experience attending a class taught by a deaf professor, Gabriel developed IA Libras to improve communication accessibility in various public settings. His project gained international recognition after winning the prestigious Swift Student Challenge in July 2026, a competition organized by Apple to showcase innovative student technology projects.
The app's development draws on advances in computer vision and deep learning, fields that have recently improved the accuracy of interpreting Libras' unique grammar and the facial expressions critical to its context. While other Brazilian projects such as TradiLibras and LibrasCam have also emerged, IA Libras stands out for its real-time translation capabilities and broad device compatibility.
According to the Brazilian Institute of Geography and Statistics (IBGE), millions of Brazilians experience some level of hearing impairment, underscoring the urgent need for enhanced communication tools like IA Libras. Although it cannot fully replace human interpreters in complex situations, the app promises to empower deaf individuals with greater autonomy in everyday interactions.
Looking forward, Gabriel plans to expand IA Libras’ vocabulary and refine its accuracy, signaling a promising path for artificial intelligence to promote social inclusion in Brazil. This innovation arrives as the 78th Annual Meeting of the Brazilian Society for the Advancement of Science (SBPC) is set to discuss themes of inclusion, diversity, and equality in science, emphasizing Brazil's growing focus on equitable access to knowledge and technology.
