There is a great news for the dumb and hearing-impaired people, with scientist testing a new mobile device which , they claim can transmit american sign language (ASL) over cellular networks. developed by the engineers That the Washington USA. 
mobile (ASL) uses motion detection technology to identify sign language and transmit video images over cell networks in the US. the tool can be integrated into any high end mobile phone with a video camera on the same side as the screen.according to the resources further research is currently done to optimise compressed video signal for sign language , with a view to increasing the quality of the images around the face and hands to reduce the data rate to 30 kilobytes per second. to minimize the amount of battery power , the mobile ASL phones use motion sensors to determine whether the sign language is being used.
