Hi Pete,

Firstly, my apologies for not replying to your message concerning technical
matters of HDTV, screen resolutions and so on. I was busy at the time, and
most of these were above my head anyway.

Videoconferencing:

You say that Michael didn't answer my original question as to why people
think that videoconferencing is tedious. I rather think that he circled
around an answer when he wrote: 

(MG)
<<<<
The latest buzz is about the use of Broadband with multiple cameras and thus
multiple perspectives being available (but of course, then you need a video
producer to manage your meetings!) or the re-creation in (virtual) three
dimensions of the folks sitting around the table as holograms/avatars able
to interact with each other in real-time--holodecks anyone--this is
available now in experimental form BTW...
>>>>

This tends to support my original suggestion that videoconferencing -- so
far -- can't replicate the real situation where people are sitting near one
another and can observe others' behaviour pretty accurately and also --
very importantly I think -- direct their gaze in a natural way when
speaking preferentially to one or other of the group.

We, and our immediate primate forebears, have been living in small groups
for, what?, two million years or so, and we must have evolved all sorts of
subtle instinctive behaviours to maximise communication. And, in fact, to
observe that a communication to another has been successfully received and
understood. I think this could have become instinctive even before the
evolution of speech.

Last night on BBC Newsnight I was observing a blind government minister,
Blunket, talking to others. For most of the time while he was speaking he
looked straight ahead of him but at the tale-end of a statement he always
flicked his gaze to look directly at the person to whom his remarks were
directed. This looked very much like instinctive behaviour to me.

I remember reading about a fascinating research project some years ago
whereby deaf people were asked to rate the sincerity of statements made by
a politician (Reagan, if I remember exactly) on the TV screen. This was
highly subjective, of course, but apparently the instances they cited
coincided with those made by a control group with normal hearing -- and
with a few more besides! 

The whole matter of 'micro facial movements' (to use Ray Harrell's recent
phrase) and other subtle non-verbal behaviour is interesting and, probably,
extremely important in a group situation. For example, we are all probably
aware that when a (male) speaker's hand rises quickly to his head (usually
to be quickly deflected to scratching his nose or neck) then it's a sign of
insincerity or dishonesty -- a sign of disguised antipathy to what he's
heard or actual lying if he himself is speaking. We register all these
things instinctively, I think, when talking to others.

To revert briefly to mobile videophones, I think that the defects of
videoconferencing will not be so evident in such 1:1 situations. There'll
be a certain amount of artificiality but not so great as to prevent it
being popular, particularly among teenagers -- as text and voicemail is
now. I have to report, however, that the DoCoMo mobilephone, which was
launched at the beginning of this week, is not due to have video facilities
until early 2002.

Even so, other big telecoms firms, such as Orange and Vodafone, are
sceptical about the viability of videophones for several more years yet.
Also DoCoMo's videophone will cost about US$400 plus charges of about
US$100 per month and these prices seem too much for teenagers -- hitherto
the prime market for mobilephones.

But there's another very fascinating aspect about videophones. This is that
because they are Net-linked all the time, then it is possible that the user
of one could be caught out in embarrassing situations when an unexpected
caller could see the background revealed by his (callee's) videophone
camera. I can foresee that the videophone will be the cause of many divorces!
