This project called Mobile ASL (American Sign Language) has created the first phone prototypes last year which are now used by 25 deaf people in Seattle. Still in the early stages of development, it wouldn’t take long for this technology to be available worldwide, embedded on all mobile phones.
These researches designed a video compression software which is very much lightweight and streamlined to efficiently deliver clear, understandable video over existing limited bandwidth networks (perfectly compatible with, both, 2G and 3G networks).
Technology would enable just about everything. We just need to wait a little longer 😉
