[comp.human-factors] Telephone - user interfaces

enag@ifi.uio.no (Erik Naggum) (06/27/91)

There are subtle reasons that the "comment" field which is used in
news is not the right thing, such as the "name" which appears below.

|   You certainly picked a bad example there.

I think it would be proper to quote from the article I wrote a little
more substantially, such as making it clear what I said.  Not all news
readers are able to grab the parent of an article, and they might not
even get alt.religion.computers in the first place.

I actually wrote:
|
|   Can you imagine a telephone which is so easy to use that you don't
|   need any time learning how to use it?  Think of it, a number, access
|   codes, dialtones, busy tone, ringing, push buttons, tones, flash, etc,
|   etc, are not at all user-friendly.  It would be much better if you had
|   a menu on the phone on which you could select with a mouse that you
|   wanted to move your phone to another office, select from a menu which
|   person you wanted to talk to, have voice feedback, "Your party is
|   busy", "Your party is now being summoned to answer the phone.  Please
|   wait."  And instead of ringing at the other end, the phone would say
|   "A PC salesman from Bogus, Inc would like to speak with you, shall I
|   tell him to bug off and forget it?"  Now think of how many times you
|   use a phone.  Now think of all the incredible losers in the world who
|   could actually _need_ a menu-based phone.  Surely that is the way to
|   go.

Now try to observe through some magic hyper-medium approximately where
in my cheek my tongue is located.

Think of it, _any_ command, request, message, idea, novel, etc, can be
encoded with the means of 12 push-buttons (*, #, 0-9).  I already said
it's "not at all user-friendly".  I don't think three-hundred button
phones would be an improvement, either.  Somehow, I think I'd like to
talk to the damn phone and say things like, "I'll be over at Lene's,
but I don't want anybody to disturb unless it's an emergency, so
forward calls to the pager, unless it's Debbie or Anne, in which case
just take their number and I'll call back.  If that rodent Paul calls,
I'm in Bergen until August."  However, a "phone" which can handle this
usually demands both salary, benefits and limited working hours, plus
lunch breaks.  I'd settle for numeric code sequences any day.

My phone and the central office I'm connected to is pretty lame in
comparison to what I should be able to get with SS#7.  I miss call
waiting, caller-id, call forward on busy, call forward on no answer,
world-wide call forward, etc.  I would _really_ like to have some kind
of notification that a busy party has hung up and is free, so I can
work while people finish talking on the phone rather than my having to
poll them at irregular intervals.  How I invoke those functions is a
secondary matter to having them.  If I can't have them because some
user interface creep decides that he has to invent another bloody
user-friendly interface first, I'm likely to strangle said creep if I
get the chance.  (This is of course not to deride the importance of a
decent user interface, but the current trend in user interface design
in which the difference between a small furry animal with fangs and a
user is size, fur and fangs, not stuff like memory and intelligence.)

Actually, I'd like a system wherein I notify people I'd like to talk
to that I would to talk to them, and then our computers can schedule
the time when that should occur with minimal waste of time.  Such a
system is more or less deployed, and it's called e-mail.

All in all, I think telephones are terrible instruments, but not
because of the supposedly evil user interface they have.  They _inter-
rupt_ me, and require synchronosity, and I spend many hours a week
trying to find/reach/etc the person I want to talk to.  The Telcos are
rumored to earn more money from people being on "hold" than people
actually talking to eachother.  Now, _that_ is user-inimical.

If you need user-friendly, call Manpower, but it costs money.

This tends to have the effect that secretaries can teach their bosses
something for a change, or put them down, if need be.  More power to
the atrocious telephone user interface!  :-)

My news postings don't have Comment: fields.  Only my mail does.

This is where you went off the rails.  It may be some amazing piece of
Norwegian subtlety, but I'm afraid it didn't work very well once translated.

Great.  I'm not proposing either of those approaches (12 button or hundreds
of buttons), because they're both awful.

Well, I wouldn't.  I don't expect a voice interface, but I expect something
better than code sequences.

No.  It doesn't matter how many functions there are; if the user interface is
so badly-designed that you can't remember how to use any of them, they may as
well not be there.  The phone system we have here does things like call
forwarding, but because of the lousy design nobody in the office uses the
features.

Look, we already have phones with crappy numeric codes and two hundred page
instruction manuals written in half-translated Japanese.  I'm suggesting that
the 99% of people who can't handle such devices should be given an
alternative.

A reasonable voice mail system is the one that's answering the NEARNET
Hotline, 1-617-873-8730.  The menus aren't too long, and you don't
need operator assistance to look someone up by name -- punch in the
first letters of the last name on the phone and it gives you the full
name and extension of the person involved.  All it needs to know is
the email address and it's just about perfect.

There are alternatives, but they cost more.  I'm only really familiar with
Mitel products, so I'll mention them, but most PBX manufacturers have sets
with similar functionality ( I'm not going to comment on ease of use :-) ).

Mitel supports the standard 2500 type set (just the 12 basic keys), and to
access all the neato features, you need to know the feature access code
that is programmed on your PBX for that feature - which is what you're
dissatisified with.

For more $$, you could get a SuperSet 4 (SS4).  This phone has an LCD display
consisting of 1 line with space for 16 characters, that displays time/date
when the set is idle, and the other party when talking.  Underneath the lcd
there are 6 keys that we call softkeys because they have no fixed label.
What each key does is indicated by a label displayed along the bottom of the
LCD screen that lines up with the keys.  These labels change with the state
of the set, so if you can see it, you can use it.  The softkeys supply
the more common features such as: transfer, conference, callback, etc.
Where input from the user is needed, you are prompted via the LCD screen.

So, better interfaces are available, they're just more expensive.

(There are other sets falling between the two in price and functionality, but
they're not relevant to this discussion.)

Disclaimer:  don't hold Mitel responsible for the above, because I'm speaking
only for myself.

Yes.  _I_ want fuctionality.  If _you_ want user interface first, go
ahead.  Invent the wheel with that attitude.  You see, you need to
interface to _something_, despite the loads of graphical user-
interface software with nice exterior and nobody home.

There are a few interesting recommendations from CCITT and other
recognized standards bodies that you might wish to learn about.  Most
of these are quite easy to master (as opposed to "learn", which is a
transient phase in any human being's development, anyway).  There is
the AT&T (BELL) command set, mostly in use in Northern America, the
CEPT command set, mostly in use in _mainland_ Europe (I know for
certain that UK is, true to form, ignoring inventions from the
continent in this area), and a Japanese command set whose acronym I've
forgotten.

Contrary to what you and perhaps somebody else might believe, the
telephone network providers have been working with user interfaces to
their network for some time.  They even write about it in books
published regularly.  The latest edition of their recommendations may
be found in the Blue Book (or 1988 edition) E series recommendations
from the CCITT (Comite Consultatif Internationale de Telegraphique et
Telephonique -- The International Consultative Committee on Telegraphy
and Telephony), located in Geneva.  If my memory serves me right, you
can write them at

	CCITT, General Secretariat
	1, rue de Varembe
	CH-1311 Geneve
	Switzerland

If that isn't right, the Swiss postal workers will probably get it
where it's supposed to get, anyhow.  You can also call less user-
friendly institutions such as British Telecom, and request the E
series recommendations from them.  I've forgotten the relevant volume
and fascicle numbers, as well as the relevant number of the recom-
mendations.
