Bridging the communication gap between deaf and hearing individuals remains a significant challenge, particularly within specific domains such as education, healthcare and public administration. Although sign languages are fully recognized as natural languages, their limited integration into mainstream communication tools contributes to the social and linguistic marginalization of deaf communities worldwide. Addressing this gap requires the development of inclusive, privacy-aware, and real-time technological solutions that facilitate seamless interaction between individuals, regardless of their different modalities of communication. This thesis aims to contribute to this objective by building an Android mobile application that integrates an AI-powered bidirectional translation engine. Specifically, the project involves the design and implementation of two distinct, interconnected modules.
