Jellow Communicator is an innovative communication tool designed to assist individuals with speech and language disabilities, particularly those with conditions such as cerebral palsy, autism, and developmental disabilities. The project was spearheaded by Professor Ravi Poovaiah and Dr. Ajanta Sen. The journey of Jellow started in 2004 as a tangible physical product. Following this, in 2008, it was made available on desktops. Then, after extensive user studies, it was conceived as a complete communication system available on a variety of platforms. Jellow has been supported by IIT Bombay, the e-kalpa project from the Ministry of Human Resources and Development, the Innovation Fund Award from Unicef, the National Trust, the Ministry of Social Justice and Empowerment, Nair Hospital, and the University of Connecticut, USA, along with several NGO's working in the field of persons with disabilities. Jellow Communicator utilises a symbol-based communication system, making it accessible to individuals with limited verbal communication abilities. It consists of a grid of symbols representing various words, phrases, and actions. Users can customise the communication grids based on their specific needs and preferences.
