Sign Language Via Cell Phone
QuatumCrypto writes "A project is underway at the University of Washington to enable real-time sign language communication via cell phone. Because of the low-bandwidth wireless cell phone network, a new compression scheme is necessary to capture only the bare essential components of signing to minimize data transfer. Although text messaging is a viable alternative for everyone, signing — like speech — is a much faster and more convenient form of communication."
But there's another problem with using sign language via cell phone. Look at the screen mock-up on that page - it shows the signers from the waist up. If your phone is far enough away that it can capture your whole body, how are you going to see the screen?
Also, they claim "The current wireless telephone network has inadvertently excluded over one million deaf or hard of hearing Americans", but it's easy to get a cell phone that supports TDD, just like a wired phone.
Visual IRC: Fast. Powerful. Free.
The technology for this is very cool and all, but I don't see it as very applicable to use with cell-phones. As far as I know requires the use of both hands, so you would have to put down your phone in a way that you can be seen and you can see the screen and lastly without holding it. This seems like an impossible proposition. But the technology in its own right could be very interesting, at least for desktop video-conferencing units.
Nothing is impossible. We just haven't quite worked out how to do it yet.
Sign language is much faster obviously, and sign language is based alot on the user's emotions and how they use a certain sign or signs.
But to answer the parent's question, none of the cell phone carriers offer a price break for deaf/hard of hearing users.
BUT the deaf community is fond of using the t-mobile sidekick, all versions, because of the relatively cheap unlimited txt/data plan that comes with it. Sidekicks are almost dominant among deaf people. Some deaf tech sites and companies offer the sidekicks significantly cheaper to deaf users since it is so popular among them.
The deaf texts a lot as well - one swedish article had a couple of deaf teenagers commenting on 3G phones and they used to send 500-1000 SMS per month. But a quick email exchange isn't the same thing as a actual live conversation (at least not for most of us)... just consider how the time gaps with texting/email makes it harder to judge the other persons mental state.
Another interesting trial project going on now in Sweden is "Translator in a pocket". It allows a deaf person to call a sign language translator who translates using the phone. Very useful for anything where you need a direct conversation with a hearing person and you couldn't plan ahead to get a translator and don't want passing notes (or what they'd use). Btw, 3G phones are very popular here in Sweden with the deaf and especially with the teenagers. I've heard numbers that something like 80% of all deaf teenagers have videophones.
When you send text messages back and forth, there's a delay with every delivery. For the equivalent of speech, this would be like calling the moon. Plus, you have to go into the inbox and open new messages all the time -- not very conversation-like or, for that matter, IM-like.
"Good news, everyone!"
There is nothing new about this story. Sign language over mobile (cell) networks already works with regular 3G (UMTS) phones in Europe. Take a trip to Örebro in Sweden, which has a high concentration of hearing impaired due to a specialist education cent(e)r(e), and you'll see loads of teenagers using their 3G phones to talk using sign language. In the streets, on the bus, in cafes, everywhere. This article http://svt.se/svt/jsp/Crosslink.jsp?d=37482&a=5369 32 (in Swedish) from February 2006 even talks of the local social security services offering customer service to hearing impaired using 3G phones and sign language.
