This prototype was designed as a part of a week long Innovation workshop organised by Techtop at Trivandrum. The objective of the workshop was to find a problem and provide a solution. After visiting the National Institute of Speech and Hearing, we identified that hearing impaired students were not able to call out each other when they are not facing each other. We designed and prototyped a solution for the same. Our work was recognized in the national newspaper "Deccan Chronicle"
