  1. Real-time Text: An Essential Accessibility Feature Arnoud van Wijk vanwijk@isoc.org

  2. Real-Time vs. Static • When calling, we use audio and/or video. Such communications occur in real-time. • It is sent and received continuously and we take the real-time part for granted. • Mostly text is static, it is on the screen and does not change at all. • Websites • Newspapers • Email • Books

  3. Using text to communicate • We also use text to communicate a lot • Text messaging(SMS) and Instant Messaging. • But if we need to communicate more efficiently, audio is always used (pick up the phone and place a call). Not IM or SMS. • But what if you cannot use the telephone? • you cannot hear or speak? • you are in a situation where voice is inappropriate due background noise, meeting, restaurant, cinema, theatre or at a conference. • Text can also be real-time!

  4. What is Real-Time Text? • Text that is sent and received on a character by character basis. (multiple characters when typing very fast) • Characters are sent immediately once typed. • Characters are displayed immediately by the receiving person(s). • Like talking by using text. Talk by Text

  5. Real-Time Text vs. IM • How it would be if you depend on IM only for your communication • IM is wonderful for exchange of text while you are doing other things at same time. • IM is not good when you need to TALK with the other person. • If IM was good for telephony why do people always switch to voice communication? • IM is a great communication toolfor the right situation and usage.

  6. Real-Time Text is standard! • Designed around the ITU-T T.140 real-time text presentation layer protocol. • T.140 allows real-time editing of text • Based on the ISO 10646-1 characterset and uses the UTF-8 format. (just like this powerpoint slide!) • Uses the same Real-time Transport as VoIP and Video-over-IP. • encoded according to IETF RFC 4103 and is also called Text-over-IP (ToIP) • RFC 5194 describes the how, why and best way to implement

  7. Website www.realtimetext.org • Goal of the R3TF: • ensure that Real-Time Text is as readily available for all users as voice is. • R3TF will create and maintain a Roadmap that will provide the basis for the full deployment, seamless inter-operability and the future development and evolution of Real-Time Text as a mainstream feature/service.

  8. R3TF • will promote the interoperability of Real-Time Text implementations with RFC4103 • will distribute information on the technology, its user requirements, and implementation and act as an educator on related issues. • is an open forum for engineers, motivated individuals, experts, companies, governments and organisations that wish to help test, implement, and advance the widespread adoption Real-Time Text.

  9. In summary: • All people can use Real-Time Text to talk using text whenever, wherever • Part of Internet telephony • Can be used simultaneously with voice and/or video. Total conversation. • also be used stand-alone for direct text to text conversations as a new text chatting function or even as an enchantment of IM. • People who are Deaf / Hard of Hearing can communicate without restrictions. • The R3TF will make this possible with your help!
