On Sign Language
Sign languages create representations in the space in front of the signer (Signing Space)
Due to the importance of vision, signed languages take advantage of spatial representations (he, she, it, etc.)
The linguistic uniqueness of sign localisation is beyond doubt

“Today’s Sign Language recognition is at about the stage where speech recognition was 20 years ago”

Challenges to ICT for Deaf
070911
The major barrier in using ICT for the Deaf is the assumption that English/ Hindi/ State language is their first language – their capabilities are often measured against understanding the written word
Most effective ICT for the Deaf is visual rather than based on the written word or sound
Text messages are limiting since it doesn’t convey emotions, voice inflections or body language (similarly Text-Speech systems)
The smart phones with front-facing cameras for videoconferencing can be used for video chat but are too much of a bandwidth hog

Future Directions
070911
Development of the ISL sign setDevelopment of software for converting Hindi/ regional
language words to ISL through online dictionary Interactive learning software using the NBT book series
for shapes, measures, colours, time, money for 2-3 year olds; newspaper and adult education for Deaf adults
Send video over both 3G and Wi-Fi networks at a very low bit rate
Optimisation of compressed video signals by increasing image quality around the face and hands to bring data rate down
Motion detection to identify whether a person is signing or not for extending battery life
