Innovation with Mathematics and Information Technology, Cluster Innovation Centre (CIC), Delhi University, along with her classmate Vikas has created a sign language-recognition system where the camera could read the signs and form a word as well as complete sentences. <br /><br />“The computer recognises the gestures and converts into alphabets.

It was called 'data glove' which had five different colours at different angles of the hand which the camera could easily sense,” says Alok Nikhil Jha, assistant professor (IT and Innovation) CIC, who helped Santoshi and Vikas in the project.“But this method was not user-friendly. So, it was decided to create a technology that could work without sensors, colours and gloves; something that could capture the movement of bare hands. For this, we needed a camera intelligent enough to decode the gestures easily,” says Alok.</p>.<p>So, they removed the gloves and called it 'Data Hands'. <br /><br />“Now, we are using the external boundaries of the gestures for the recognition. The system is of no use if it is not able to make sentences out of the known gestures. </p>.<p>So, there is a green rectangular box at the top of the screen, on which the alphabets recognised by the camera is jotted down.<br /><br />”Notably, it becomes a lengthy process as gestures for each alphabet has to be made to form a word.

What we are working upon is that it should be able to recognise a word as a whole. <br /><br />Therefore, we are focusing on the Indian Sign Language. If we are able to create a technology that can easily understand the Indian signs, it will be a boon for the disabled,” says Vikas.<br /><br />Presently, both are working on improving the accuracy of the system. “For the system to directly read words we need to create a huge data base.
