Hearing impaired can use mime on cell phone
Washington, Aug. 17: University of Washington engineers are developing a tool which would be able to transmit American Sign Language over US cellular networks.
“This is the first study of how the hearing impaired people in the United States use mobile video phones,” said project leader Eve Riskin, a UW professor of electrical engineering.
MobileASL optimises compressed video signals for sign language and delivering intelligible sign language at a data rate of 30 kilobytes per second. It also uses motion detection to identify whether a person is signing or not, in order to extend the phones’ battery life during video use.
Transmitting sign language as efficiently as possible increases affordability. It improves reliability on slower networks and extends battery life, even on devices that might have the capacity to deliver higher quality video. “The field study is an important step toward putting this technology into practice,” Ms Riskin said. Most study participants say sending text messages or email is currently their preferred method for distance communication. Their experiences with the MobileASL phone are, in general, positive.
“Texting sometimes is very slow. If you’re using this kind of phone then you’re either able to get in touch with the person or not right away, and you can save a lot of time,” said Tong Song, a Chinese national who is studying at Gallaudet UW.
