Who doesn't have a cell phone in this crazy society? But how many Deaf use a phone? I guess the number increased since we now have text messaging. But I am sure signing would be more comfortable for them. There is a project at the University of Washington in order to make wireless cell phone communication through sign language a reality.
The main problem now is the low-bandwith wireless cellphone network, so they are working on a new compresion scheme. The software uses skin detection algorithms to zoom in on those specific areas in the video that contain essential movements used to communicate via ASL, typically, hand, face and arm movements. You can read the BBC article about it.
There is also another project to help people who have lost hearing abilities.
And more about this topic. What to do if your son is born deaf? You should learn how to sign. This family is having problems with it. Read a little more.
