Telephone in sign language

The basic function cell phone for our brothers who can not speak or hear may only be limited to short messaging. With this technology, our brothers who are less fortunate are able to communicate using cell phone short-messaging is not only just. You who are in front of the cell phone is placed on the table just use sign language.

Is this like a video call? Somewhat different. Here cell phone will capture the image, then compress very little. Results are sent to capture the speed of 15-20 kbps and 10 frames per second (fps). The use of compression is much more efficient than the use of video calls.
