J. Philip Craiger and R. Jason Weiss
University of Nebraska at Omaha
Welcome to the last installment of Traveling in Cyberspace. Mike
Coovert wanted to make this issue of TIP a special one, given that it would be the
last under his editorship. He challenged us to come up with a very special topic on how
technology will change the world of work in the twenty-first century, and we rose to the
challenge. We wanted to interview a visionary, someone who has had, and will continue to
have, a major impact on technology. We could think of no one better than Donald Norman,
who was kind enough to grant us an interview.
Dr. Norman has been a leader in the fields of cognitive science and
human-computer interaction for many years. He served on the faculty of the Department of
Cognitive Science at the University of California at San Diego from 1981 to the present,
and is currently Professor Emeritus. From 1993 to 1997 he served as Apple Fellow at Apple
Computer, Inc., and as Vice-President of Apple Research Laboratories from 1995 to 1997.
Currently, he serves as head of the Appliance Design Center for Hewlett-Packard. He is the
author of multitudes of publications and books. One of his more popular books is The
Design of Everyday Things, published by Doubleday. (This is one of our favorite books
of any kind, and is a MUST read for anyone who thinks they are too inept to program a VCR!
Hint: Its not your fault, its badly designed!).
Because Dr. Normans vita is actually longer than this column,
well point you to his Web site for more information: http://cogsci.ucsd.edu/

What doesnt come across on these written pages is Dr.
Normans great sense of humor. And without further ado, here is our interview with
Donald Norman:
*****
P.C. I write a column with Jason Weiss, my graduate research
assistant. Its called Traveling in Cyberspace. Its written for the
national publication of the Society for Industrial and Organizational Psychology.
Weve got a special edition coming out in April, and what I wanted to do is ask you a
few questions about some of your philosophies that you developed over the years,
particularly in terms of computers, humans, and the world of work.
D.N. OK. Hi Jason.
R.J.W. Hello.
P.C. First, I wanted to give you the opportunity to tell us a
little bit about your new book called Information Appliances that is coming out
from MIT Press later this year. Could you give us an overview of that?
D.N. Sure. Actually, the title has changed. The title was
originally going to be Taming Technology. Its what it is about. I then
changed it to Information Appliances, which is my suggested solution. What
its really about is making computers invisible. The new title is The Invisible
Computer.
P.C. I like that! Could you talk a little bit about what you
discuss in your book?
D.N. Mainly I believe that todays personal computer is
just fundamentally the wrong approach. Its a machine that is developed by technology
companies, by technologists, for technologists. Yet the majority of the public are not
technologists, and the public wants consumer goods. In the early days of any technology,
when a technology isnt really quite up to par, products are technology driven, and
they are driven by engineers. Basically you could do no wrong, and with each new release
of the product you have more and more technology, and thats what customers clamor
for.
With time, as technologies mature they move into the consumer phase.
Now what consumers really want is convenience. One of my favorite examples is that you go
to the kitchen to use an eggbeater. The name of the device in fact tells you what it is
for and it does not name the technology. It is not named an electric rotor with hooks.
P.C. [Laughs] Thats true.
D.N. So we still go to use our personal computer, which is
wrong; its not really very personal and we dont want to do computing.
P.C. Thats right. In fact, thats one of the things
that Ive read that youve said. The word "personal computer" is a
really poor term for what we call the PC.
D.N. Right, exactly.
P.C. Well, what would you have called it?
D.N. Well, what I would prefer to call it in the future is by
the name of the task it does. So when I say I would like to see information appliances
what I want to see is the computer disappear into the device. For example, if you take a
musical keyboard or a drum machine or an electric guitar, you dont think of these as
computers, and you dont think of them as information appliances, but they are.
Theyre computers, theyre information appliances, but theyre very well
specified by the task that they are doing. The whole physical shape and form is
specialized for the task. And they have a very powerful standardized information protocol
so that any one of these can talk to any one of the others. Its called MIDI. And
thats the paradigm that I would like to see.
A calculator is another good example of an information appliance. Even
though a computer really does a fine job of calculation, we quite often prefer calculators
for lots of reasons. One factor that is very nice is that it is very easy to enter the
equations or the numbers. We have specialized calculators, whether it be a normal
arithmetic one, or a scientific one, or a financial one, and more important, you can take
the calculator to where you do the work. Today, we have to take our work to where the
computer is located. So the only problem with the calculator is that it is self-contained
and independent so that you cant connect it to anything else and take advantage of,
say, some other device that might spit out numbers which would be just perfect for the
calculator to take as input.
P.C. That is interesting. As an industrial psychologist one of
the things with which we are concerned is training, and too often we find it is very
difficult to get people trained for a job, or a particular device, because of the
resources that are available. For example getting a trainer to a particular location and
getting everybody involved together at one time. One of the things that has been touted
about the Web is that it has the ability to provide training to workers and educating
people of all ages anywhere, anytime, just-in-time training to mass audiences. In your
opinion, is this a "pie in the sky" idea, or do you think that could be reality
in the future?
D.N. Thats a very complex question, so let me take it
apart. The normal people would say "hooray!" for the Internet and how we will
dramatically revolutionize training. Thats not a pie in the sky, thats a pie
in the face. So basically, what is the worst way of teaching somebody? Answer: the
lecture. So we take the worst way of teaching somebody and actually make it even worse.
Then instead of lectures, we put it in text and little cam videos and now we distribute it
over the Internet. This does not enhance education. Just-in-time learning actually uses a
very, very different concept. The proper just-in-time learning is exactly the minimalist
training that Jack Carroll talks about. You know his book about minimalist training?
P.C. Im familiar with it, yes.
D.N. What Carroll discovered was that all these big manuals
were worthless because people looked at them and said "Yaaa! Why do I want to read
this? I just want to know what to do." And so what he proposed and showed and what
really worked was that you give people the absolute minimal instruction and let them get
started on their task. And theyre really happy because theyre actually
accomplishing something. And then as theyre doing their task they run into trouble.
Thats when theyre ready for just the right amount of information to tell them
how to proceed. Thats what just-in-time learning is about. Its not bombarding
you with lots of information. But its giving just what you need at the time that you
need it. And this is not what most of the people are talking about when they talk about
Internet training. I was just at a conference and I saw some novel schemes, Internet
training, and these people confuse cuteness, for example, with education.
P.C. Right. Ive seen that. More glitz than substance.
D.N. Right. I think the Internet can revolutionize things, but
the traditional way its being done, Im not a fan of. The one institution that
I think has done an excellent job at learning at a distance and using the Internet is the
Open University in Great Britain.
P.C. Ive heard of that, but I have no experience with
them
D.H. Check them out on the Web. They have something called
Knowledge Management Institute. I dont remember the URL, it might be KMI.
P.C. Oh, Im sure I can find that. Is that part of the
Open University?
D.N. Yes. It might be KMI at OU. Who knows what it would be?
Whatever the complex stuff might be probably .ac.uk or something.
P.C. One of the things that you have prominently on your Web
site is the motto from the 1933 Chicago Worlds Fair that says "Science finds,
industry applies, and man conforms."
D.N. Right.
P.C. And then you have your own person-centered motto, which I
liked very much which is "People propose, science studies, and technology
conforms." Can you expand on that? That is, on your person-centered motto for the
twenty-first century, in particular in terms on how it might apply to the workplace, and
how work will change because of technology?
D.N. Actually, what Ive taken is from my book Things
That Make Us Smart where I do go into this in more detail. And actually in my new
book, The Invisible Computer, I discuss what happened with the mechanization of
work so what happened around the turn of the century as we introduce so- called scientific
work practices, Taylors work on scientific work practices. And for that matter,
Henry Fords work on the assembly line, and earlier than that, the work on the meat
packing factories where they did what might be called the "disassembly" line.
The whole philosophy there was to try to take work apart into small segments to treat
humans as machines, and then give each person very tiny segments that they could do
repeatedly. Taylor, for example, thought of his laborers as brute laborers and didnt
think they were capable of thought, and on top of that, didnt think it was
appropriate for them to think while in the workplace. Because after all, if you stopped to
think, it would slow you up. So his notion was that you should just decompose the work
into small segments and that required no thought and you could do efficiently for the
whole day. What he failed to understand was people. Thats just not a very high
morale situation. It dehumanizes the workforce, and it leads to alienation of the workers
from the so-called "superior" managers who are doing the decomposition and who
are doing the thinking. I think the current status of the workforce in many ways had its
roots around the turn of the century as we try to do scientific analysis of work habits.
It didnt take into account human psychology.
What is happening today, I think, is that were better able to
understand that you need motivated workers. You want workers to feel that they have made a
sizeable contribution to the device that they are producing, to the product. And that
makes a dramatic difference. And even if they are a little bit slower at each operation,
by the end of the day, they are much more efficient. So we see some of the harm that
happens to long distance information operators. Psychologists determined that if you can
save a second or two off from each telephone call, you can save tens of millions of
dollars for the telephone company per year. And as a result it is a horrible jobyou
just sit there, and you dont even say "hello" to the customers. The
"hello" to the customers is now done today by a computer-synthesized voice, and
they only get to hear what your question is, and then they turn you over to an automated
system that gives you the answer. You may have noted that you get to talk to the operator
for only a few seconds and then that person is on the next call, and the next call, and
its a horrible position, a horrible job to have.
P.C. One of the things that Ive found interesting in the
last few years is the issue of telecommuting. Business teams no longer have to be situated
in a particular physical or even geographic location. Business teams now, especially for
larger organizations, can be situated throughout the world. This appears to be totally
technology-driven, you know, the ability to communicate with each other in various ways,
and also an increase in the bandwidth has created that flexibility to not have to be
situated in a particular place or even a particular time.
D.N. Well, some of it you might think of as technology but some
of it is out of necessity. Yes, technologies have allowed companies to become
international. Before the days of rapid travel and rapid communication, companies could
not actually service an area much larger than their homebase. And before the advent of the
telephone, the company had to have its sales in the same place as the manufacturing plant.
The telephone made a big difference in that. So did the telegraphs and before that the
trains, and today, of course, the more modern communication methods. As for international
situations, for example, Im working with a group in Bristol, England. I cant
afford to go to Bristol, England every week. So working at a distance becomes absolutely
essential. I used to have people that worked for me that lived in Minnesota, so new
technology allows this. So Im not sure its technology driven. I think
its actually need driven.
A very interesting book that Ive been reading that is called the Death
of Distance, which is arguing that although distance is now disappearing, time zones
remain.
P.C. [Laughs] Thats true.
D.N. In fact, its time zones and language that determine
more and more how people collaborate with each other. So Im having great trouble
actually working with my group in England, because unless I can contact them before ten
oclock in the morning theyre not at work any more. And I tend to be a late
worker; I tend to get to work at ten. So the window is almost non-existent. I find the
real problems are time zones. Now we have found in doing software development we can take
a chance at the time zone. We have our software group in India start to work on our
project, and when they go home for the evening they send it off to California, who works
on the project, and when they go home for the evening they send it off to England, who
works on the project. So what you have is 24-hour-a-day work on the same project.
P.C. So one team would work on a piece of software and send
that to another team which would continue on?
D.N. Not all projects allow that kind of handoff. But there are
certain things, especially in the testing phase, where you can actually do as much testing
as you can in 8 hours, and then pass it on to the next.
P.C. Ive got two more questions, I know youre very
busy, Dr. Norman. One of them deals with something that was in Chapter 6 of Taming the
Technologywhat your book was formerly called.
D.N. At this point, I dont remember, the book has been
changed so much. I promised myself this weekend to put up a more accurate version.
P.C. What it referred to was activity-based appliances.
If you could to describe how you got started at Apple with activity-based computing,
in particular what ramifications you think that has for selection of workers. Because now
we start with a job that has been designed, and we have hardware and software and other
implements that are used to complete tasks. As industrial psychologists, what we do is try
to match the person with the task. But it appeared to me that some of things that you were
saying about activity-based computing could actually allow you to be more flexible in
selecting workers. What you would do is engineer and design the computing devices to adapt
to the individual. Am I off-base there?
D.N. Actually we didnt emphasize adaptation there. We
emphasized trying to do good task analysis, if you will, and designing the system around
the full activity that is to be performed. Instead of trying to optimize some local thing
like word processing, people dont want a word processor. They are writing letters,
or papers, or memos, or something. People dont write checks, theyre doing
financial transactions, of which writing the paper or writing the checks is one small
component. So the argument is, if you can support the whole activity, the tool is much
better fitted, much better in aiding you to accomplish this task. My opinion is that it is
pretty simple and is a pretty straightforward idea.
P.C. Did you think that some of these systems that support work
are going to involve artificial intelligence?
D.N. Artificial intelligence is already in active use. A lot of
intelligence search engines use techniques from AI. But I certainly dont believe in
a system that tries to read your mind and try to get your attention.
P.C. Oh, no. Right.
D.N. In those senses no. In the sense though of doing
intelligent searches and finding things that are say, similar to the document that you are
looking at, then yes, then those have already proven to be effective.
P.C. I just have one more question. My GUI Design class would
appreciate your answer on this. Something that you said in the same chapter when you were
talking about whats wrong with the GUIs today. What you said was that they
"just dont scale" and you wrote "making everything visible is great
when you only have 20 things but not 20,000." My question to you is what do you think
that some of the interfaces of the twenty-first century will look like; how different will
they be than some of the current interfaces we use?
D.N. Actually I would hope that the best interfaces are the
ones that you dont notice at all. Think about what the electric guitar is. If you
actually think about it, the electric guitar is a pure interface mechanism. You play
music, you play electric guitartalk to somebody who uses one. What it is, is a
wonderful set of strings and frets, and you can basically use this to control the sound.
But the kinds of sound that come out of them is determined by the sound generator. It has
nothing to do with guitars anymore, and thats a clever interface.
What I expect to see is more and more interfaces that are tailored for
the task that you are trying to do. I just saw a demonstration of a gesture interface
where you just move your hand and point to the object. You can play games as to where you
see the ball coming at you, you lift up your hand and you swat it. I can imagine in doing
gardening, my gardening tool might have a probe that you stick in the ground and made with
a little camera that I aim at the plants so that the system can measure ground acidity and
moisture, and identify the plant, photograph it, and tell me what I should be doing. What
I expect to see is the interface tailored to the task far better than what we do today. So
today we sit down with the mouse and the keyboard, which isnt relevant to gardening
or relevant to making music. So that is what I expect to see. As the computers become
invisible and we are embedded in task-specific devices, the interface will be appropriate
for whatever work were doing.
R.J.W. Dr. Norman, if I could ask you a question myself. When
you talk about having particular tools such as the calculator, and thats just a
calculator. The computer can do a number of things that have no relation to each other,
such as word processing and surfing the Internet. So you mentioned before you dont
like the term "personal computer," its not a good term. What term would
you use for such a multipurpose tool?
D.N. Why do I want a multipurpose tool?
P.C. [Laughs] Good question.
R.J.W. Well, to save on space, I guess. Instead of having a
word processor and something that sits right beside it that surfs the Web.
D.N. Youre missing the point. How many devices do you
have already in your house? You have a huge number of devices in your house. The point is,
you put them where you need them. You dont stick them all on top of each other. So I
dont want a word processor by the way, I want a letter writer or I want a report
writer or a paper writer. And I will put that where I want to write my papers or my
letters. And I wont have a Web browser, I suspect. Ill have many of them, so
there will be a Web browser built into the TV set and Ill use that for
entertainment, and checking out advertisements that I have seen on the TV shows that I
watch. Im sure my children will have a homework machine, and they will browse the
Web probably provided to them by the school. Ill have a financial center where I pay
my bills, and my income tax, and maybe my investments. Ill browse the Web, probably
provided by my financial institution to learn more about my investments.
So how to make everything into one device misses the point. I want to
choose to work in the different locations in my house, and there I want a tool that is
appropriate. I just saw a very nice device at a communication center, the telephone.
Its got a telephone, voice mail, and e-mail, and does Web browsing. I would have
that in my kitchen but I wouldnt do full Web browsing. I might use it to look up the
weather, or I might connect to my sons school connection so that I could see when
the soccer game was, or when the plays are. So I would expect to see these scattered all
through the house, much like all of our normal devices are scattered throughout the house.
You have many telephones throughout your house which you put them where they are
convenient. Does that answer your question?
R.J.W. Yes.
P.C. That surely did. Dr. Norman, our time has run out. I want
to thank you very much for sharing your thoughts and philosophies with us.
D.N. Fine, thank you very much. Bye.
