  7. Problems with fluency Simon ~ In the office... says: Hi - How is your meeting going? Well? • Claude - In Paris - Back on Monday says: • Yes - all is fine! • Simon ~ In the office... says: • Is George in the same meeting? • Simon ~ In the office... says: • Could you bring something back from Paris for me? • Claude - In Paris - Back on Monday says: • No! • Simon ~ In the office... says: • Oh … but its for my girlfriend’s birthday and I’ll repay the favour – please! • Claude - In Paris - Back on Monday says: • No!!

What is text conversation? • Text appears at each end character by character as it is typed • The two parties have the feeling of being in continuous contact • Just as in a spoken conversation User A User B Why do you need character by character transmission? Because then you get a feeling of being continuously in touch. Yes, I see, I can almost read your thoughts as you express them. No waiting. Good! Text communication for all "DUST"

  9. A bit of history • Text telephony started in America with old teletype machines in the 1960s • Various other Countries started with newer “improved” terminals • Unfortunately - There was no harmonisation • Result – 5 different systems in Europe • Worse – They can’t talk to one another Text communication for all "DUST"

  10. Result • Deaf users caught up in generally national systems • With full text access limited to other deaf textphone users • Seven kinds of legacy PSTN textphones • Will not disappear tomorrow • ITU-T V.18 compatible with all • Most deaf users do not have access to 112 emergency services Text communication for all "DUST"
