About Jellow

General Information

Jellow Communicator is a friendly Augmentative and Alternative Communication (AAC) system that uses icons/images to enable speech. This application can be used for communication by those learning to speak or those having difficulty with speech. Jellow can also be used by toddlers and early learners to learn words and categories frequently used in their daily lives. Jellow's colorful and friendly icons can help children develop an association between pictures and their corresponding word labels.
It is developed at IDC School of Design at the Indian Institute of Technology Bombay (IIT-B) located in Mumbai.
A novel Emotional Language Protocol or ELP was concieved and developed by the project investigators in order to enhance the language ability of Jellow. ELP represents the 6 expressive icons that form the core of the interface.
Using these core icons, the child can communicate their likes, dislikes, and needs with others.
Jellow has around 1000 icons and over 10,000 lines of pre-programmed text. In addition, using the 'keyboard' feature, the user can also generate new sentences and use the app to speak them out aloud.
Jellow is conceived as children-friendly with an easy-to-learn interface.
The application is optimized for Android and iOS mobile devices.
