University of Ibadan dons develop AI-powered sign language device

Four University of Ibadan lecturers have developed the Digital Gesture Assistant Device, an Artificial Intelligence-powered tool designed to bridge communication gaps between the hearing-impaired and the hearing world. This innovative device enables bidirectional communication through three key functionalities: translating speech into sign language, interpreting sign language into spoken words using an AI-powered camera and enhancing voice clarity through a feature called “Gesture Link.”

The development, led by Dr. Adeniji Oluwashola David and inspired by the 2022/2023 TETFAIR program, involves computer science, medicine and education experts. Team members include Dr. Adebolajo Adeyemo, an ENT surgeon; Prof. Bolanle Oladejo, an AI and software engineering specialist; and Dr. Udeme Samuel Jacob, an expert in special education.

The project’s genesis can be traced back to Dr. Adeniji’s participation in the TETFAIR program, a platform encouraging technological solutions for societal challenges. In 2024, his proposal for an AI-driven communication tool attracted a multidisciplinary team, leading to the creation of a functional prototype. The prototype translates sign language into spoken words and supports multiple local Nigerian languages which makes them accessible to diverse communities, thereby promoting inclusion on a national scale. This device empowers hearing-impaired individuals to engage fully in education, employment and social interactions.

As the team refines the device for mass production, this groundbreaking achievement emphasizes the power of innovation and collaboration in breaking communication barriers and transforming lives. The Digital Gesture Assistant Device signifies a monumental step towards inclusivity for Nigeria’s deaf community.
