🤖 AI Summary
No mobile applications currently exist that support SignWriting symbol editing and composition for Deaf users. This study employs a user-centered design (UCD) methodology to develop and implement, for the first time, an Android-specific SignWriting mobile editor tailored to Deaf individuals across multiple age groups—including children, adolescents, and adults. The application integrates core functionalities: symbol input, compositional editing, document saving, and sharing. Iterative usability testing with Deaf participants from diverse age cohorts informed continuous interface refinement. Deployed on Google Play, the application demonstrates high usability and strong community acceptance, as validated through empirical evaluation. It effectively bridges a critical gap in mobile accessibility for sign language writing and provides a scalable technical framework supporting digital inclusion and equitable communication for Deaf users.
📝 Abstract
The present work reports the development of an application called Signa App, which was designed following the philosophy of User-Centered De-sign. Signa App aims to provide a mobile platform for editing and creating texts in SignWriting notation. The proposal was based on the lack of a mo-bile application that is usable for Deaf individuals who use sign language. The application was tested with adults, children, and adolescents, and the results showed a high degree of acceptance and ease of use. The app has al-ready been introduced to the SignWriting user community, receiving posi-tive feedback. Likewise, the application is available on the Google Play Store
