We designed and developed the “STASY Sign Language Guide” app, which was awarded a Gold distinction at the 2025 Boussias Tourism Awards as a leading accessibility solution for travelers with disabilities. The app supports independent mobility for people with hearing impairments by providing travel information and emergency announcements in both Greek and International Sign Language, with parallel subtitling in Greek and English. Through this initiative, technology is transformed into a meaningful tool for inclusion, digital accessibility, and social equity.
