This application was created as a 3D animation text translator for the Indonesian Sign Language (SIBI) system.

Through the application available on the Play Store (Android operating system) and App Store (iOS), users can choose one of the two 3D animated character options available. There are Andi and Aini who will help users translate the desired sentences into SIBI in animated form.

The application is designed to be able to translate more than 300 thousand words and affixes.
