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."

Re:Video calls

[dotancohen]

Yes, we hold the phone for him. I've also got a Nokia 6280 with video calls. The video calls at 0.46 NIS/m are cheaper than regular phone calls at 0.67 NIS per minute. The boy is question is not only autistic but also mostly deaf. What's interesting is watching young kids talk on the phone. Even on a non-video call they nod yes and no.

Sign language text and language

[Anonymous Coward]

Not all deaf can just use text. Some know only sign and don't know any English. It is impossible for them to use TTY's or other text. And even if it is possible, it can be slow and painful. Learning English text when you can't hear is a very very difficult thing to master. Especially literacy in a second language when you're illiterate in your first language. Stefan Wöhrmann in Germany has had great success teaching German text to deaf, but he uses written sign language for teaching.

"What is the benefit over txt messaging?"

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.

I know a few deaf people and

[zoomshorts]

They are flocking to the Sorenson VP-100 system.

I cannot, for the life of me understand this, when there
are so many video based chat sites on the net.

All the deaf people I know have PC's. I met my first
deaf friend on the old BBS's. In the text messages on
FIDOnet.

I would not want a deaf user signing while driving :P

Videophones

[Zarhan]

At least in Finland, in cooperation with a Finnish hearing-impaired association, there's been some projects with 3G video-phones. Yes - selling a phone to deaf people opens up a nice new market :). Anyway, as far as I know the experiences have been overall positive - and no fancy sign-language-specific codecs or anything, just a normal 64kbps video phone call and a camera phone.

Re:Sign language and speech faster than typing?

[mr_matticus]

Either you talk too slow or you've broken some land-speed records for typing on handheld devices. Typical English conversation is roughly 200 words per minute. Most of the population can't type faster than about 60 words per minute on a standard keyboard, let alone a cell phone-sized thumbpad.

Even if you type at double that (120wpm), you're still typing slower than you speak. As for the input device, how would you go about making a pocket-sized keyboard as efficient as a desktop version (which you can put down and use all fingers to type--no such possibility with a cell phone)? Having to have the physical input device AT ALL *is* the problem to be fixed here.

Sign language over mobile works on 3G already

[threepoyke]

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 [svt.se] (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.

Re:TTY?

[thevil]

The benifit is that sign language is the first language for a lot of people.
English is their second language.
