People should always be able to decide what format they like / want. Because people are used to IM being en-bloc - I would think that products should sup with the XMPP in 'en-bloc' or regular IM mode. But the RTT or FastText button should be very easy to see and use -- and to use to switch back and forth as the occasion demands.
Once a person sets their preference - it should persist from one use to the next (by the same person). Except for the situation where people have not seen RTT before -- it would be much like talking. ANd people are always saying things they would like to take back sometimes - before they finish their sentence. But all of this is design of the app -- and outside the specification - yes? (except for the part about the app should ALWAYS advertise its capability to do RTT along with other capabilities) Gregg -------------------------------------------------------- Gregg Vanderheiden Ph.D. Director Trace R&D Center Professor Industrial & Systems Engineering and Biomedical Engineering University of Wisconsin-Madison Co-Director, Raising the Floor - International and the Global Public Inclusive Infrastructure Project http://Raisingthefloor.org --- http://GPII.net On Jun 29, 2012, at 8:20 AM, Winfried Tilanus wrote: > On 06/28/2012 01:45 PM, Mark Rejhon wrote: > > Hi, > >> But, you know, aren't audio and video potential privacy issues too? >> Especially if used during the wrong times?
