Norbert Weiner
(1894 - 1964)
Today there are
few scholars who can call themselves mathematicians or physicists or biologists
without restriction. A man may be a topologist or an acoustician or a
coleopterist. He will be filled with the jargon of his field, and will
know all its literature and all its ramifications, but, more frequently
than not, he will regard the next subject as something belonging to his
colleague three doors down the corridor, and will consider any interest
in it on his own part as an unwarrantable breach of privacy. -- Norbert
Wiener
Norbert Wiener was a mathematician and innovator
in several fields. Fascinated by machines, he linked mathematics to engineering,
developing a statistical theory of communication. This theory would impact
the design of every kind of communication system, from telephone networks
to satellite relays to computers to information networks. Wiener's mathematical
theories led to the development of noise filters used in radar observations,
radios, telephones, and numerous other devices in common use. In the 1940s,
Wiener's recommendations for calculator technologies led directly to the
invention of the electronic
digital computer. Wiener's genius for linking mathematics and engineering
with an understanding of the social and philosophical impact resulted
in his seminal book, Cybernetics, or Control and Communication in the
Animal and the Machine, written in 1948. Later, in 1950, Wiener wrote
the more accessible and popular The Human Use of Human Beings.
Interdisciplinary
approach
Interdisciplinary
thinking and practice was key to Wiener's approach to engineering, which
led to the development of the electronic digital computer and the field
of artificial intelligence. He felt that contemporary science required
an interdisciplinary approach due to the convergence of the fields of
biology, neurology, and mechanical and electrical engineering.
Wiener's 5 principles
of the digital computer.
The principles of
the electronic digital computer were laid out by Norbert Wiener in a 1940
memorandum, the technological foundation of computing that is held to
this day.
- 1. digital rather
than analog
- 2. electronic rather
than mechanical
- 3. binary rather
than decimal
- 4. automatic rather
than manual
- 5. memory storage
rather than repatching
Neurological roots
Wiener's theory of
computing was based on systems derived from the human neurological system,
"as we shall see...they are all ideas which are of interest in connection
with the study of the nervous system. To this day, the microprocessor
in designed like that of the human brain, with transistors emulating neural
synapses, routing messages along complex paths like that of the human
nervous system.
Calculating Ballistics
Wiener also emphasized
the need to develop digital computers for the purpose of measuring complex
trajectory tables for missile ballistics. During World War II, the first
electronic digital computer (ENIAC) was developed for this purpose.
Human-Machine Coupling
At the core of Wiener's
thinking was his desire to develop new human-machine systems built on
the idea of cybernetic feedback, incorporating digital technologies. It
is this notion that is key to artists' interest in Wiener, as this thinking
is the foundation of interactivity as we know it today in regards to the
human-computer interface. Artists studying interactive multimedia forms
can benefit from an understanding of Wiener's seminal engineering breakthrough
in this field.
The following are the key concepts that make up the theory of cybernetics.
One of Wiener's key
contributions to electrical engineering was the notion of feedback and
how its function can be described as mechanical systems coupled with human
systems. (He later went on to write a book entitled, "The Human Use
of Human Beings," in which he goes to great length to describe this
concept.). Wiener defines feedback as, "when we desire a motion to
follow a given pattern the difference between this pattern and the actually
performed motion is used as a new input to cause the part regulated to
move in such a way as to bring its motion closer to that given by the
pattern." If we are driving an automobile, our movement of the steering
wheel is made in direct relation to the motion of the tires and axles
and the direction of the road. When the road turns to the left we respond
by turning the steering wheel to the left, followed by the changing movement
of the car giving us feedback to our initial steering action. The success
of this feedback and resulting action is based on the relationship between
the car's mechanical system and the human system's ability to respond
accordingly.
Wiener determined
that there was a direct correlation between electrical engineering and
the human nervous system, in terms of how messages are relayed. He says,
"... the problems of control engineering and of communication engineering
were inseparable, and that around the much more fundamental notion of
the message, whether this should be transmitted by electrical, mechanical,
or nervous means. The message is a discrete or continuous sequence of
measurable events distributed in time..." The information network
functions analogously to the human nervous system, messages sent between
the brain and the rest of the nervous system to activate bodily systems.
Entropy refers to
the disintegration or disorganization of information. "Just as the
amount of information in a system is a measure of its degree of organization,
so the entropy of a system is a measure of its degree of disorganization,
and the one is simply the negative of the other."
Wiener writes, "We
have decided to call the entire field of control and communication theory,
whether in the machine or in the animal, by the name of Cybernetics,
which we form from the Greek steersman. " Wiener determined
that the steering of ships was one of the most ancient forms of cybernetics
(human systems coupled with mechanical systems) and provided an ideal
name for the field.
Reading: Norbert Wiener,
"Cybernetics in History," Human Use of Human Beings : Cybernetics in Society,
Houghton Mifflin Co., Boston, 1954
"Society can
only be understood through a study of the messages and the communication
facilities which belong to it; and that in the future development of these
messages and communication facilities, messages between man and machines,
between machines and man, and between machine and machine, are destined
to play an ever increasing part." Norbert Wiener
Norbert Wiener authored this exposé on the nature of human-machine
communication five years after publishing his famous treatise, "Cybernetics"
in 1948. Responding to a need to make his revolutionary new theories on
information science and machine control accessible to a broader public,
the Hungarian-born mathematician and child prodigy (who received his Ph.D.
from Harvard at the age of 18), wrote The Human Use of Human Beings to
elaborate on the relationship between cybernetics and the greater social
ecology. In this book the electronical engineer and communications expert
turns to the sociology of human dynamics to formulate a theory for how
human beings will come to interact and co-exist with computers.
Wiener describes the often maligned term 'cybernetics' as having its roots
in the Greek word for "steersman" or "governor," creating
a theory of how humans dynamically operate and interact with machines
through a controlling device such as a steering mechanism. Driving an
automobile, passing through an automatic door, or clicking on a mouse
would all be examples of cybernetic actions. Weiner thus defined cybernetics
as the science of how messages are transmitted between man and machine,
and between machines, in which the quality of the transmission is determined
by such critical factors as 'feedback' and 'noise.' The significance of
Wiener's research remains particularly prescient due to the fact that
he viewed human communication as a model for the way machine interaction
should be designed. For as Wiener stated, "the fact that the signal
in its intermediate stages has gone through a machine rather than through
a person is irrelevant."
Weiner further describes how engineering problems inherent in cybernetic
systems are deeply embedded in the larger culture where interaction with
machines is integral to our existence. He claims that the quality of external
communication in a technological society is essential to man's inner being
and relationship to the outer world. This view coincided in Weiner's mind
with the shift in physics in the early part of the 20th Century (particularly
through Einstein's Theory of Relativity), in which the physical world
was viewed more subjectively not as it actually exists but rather
how it is observed. This epiphany coincides with the post-modern condition
in which we have come to observe the artwork, not as a self-contained,
closed entity, but as an active collaboration and interaction between
the artist and the viewer, in which the latter responds, manipulates and
offers feedback as an open and evolving system of messaging and communication.
Douglas Engelbart (1925 - ) Boosting the Collective
IQ
"So one Saturday morning in all that stewing
around it just dawned on me. Hey, you know, the world is really complex.
And a lot of the big problems can only be dealt with collectively. And
they're getting more and more urgent and more and more complex. And mankind's
ability to cope with complexity and urgency isn't keeping up with the
degree of increase in those factors. So here I come. I get on my white
horse and I can do that for mankind. See?" -- Douglas Engelbart
Douglas Engelbart, lone
scientist working amidst ridicule and ignorance, never once strayed from
his vision to help people use computers to augment their thinking in order
to become more productive, creative and smarter. When Engelbart first
had notions of building interactive computers for knowledge workers, these
machines were behemoths in the basements of military research centers
being used to calculate missile ballistics. But in 1950, when Engelbart
was working at Ames Laboratory in the pre-silicon valley days of Northern
California, he realized he had fulfilled his dreams, and lacked the goals
he needed to propel him further. A few days later it hit him square in
the face, that his knowledge of engineering, radar technologies, and computing
could be used to augment the human intellect, to "boost the collective
IQ."
Engelbart was one of the early information pioneers to see the connection
between the computer and the cathode-ray tube. Twenty-five years before
the first personal computer, he envisioned interactive computing patterned
after the Memex for the storage, retrieval, processing, and association
of information. Despite the skepticism of his colleagues, Engelbart persevered
— in 1962 he finally publishing his ideas in the seminal article, "A
Conceptual Framework for the Augmentation of Man's Intellect." This
article attracted the attention of J.C.R. Licklider of ARPA, and Engelbart
was awarded the funding he so desperately needed to realize his vision.
oNLine System
To build his augmentation system, he founded the Augmentation
Research Center at the Stanford Research Institute in Menlo Park, and
for the next four years, together with a young team of progressive engineers,
proceeded to build the first prototype of NLS (onLine System). By 1968,
Engelbart and his team bravely presented the highly experimental NLS at
the Fall Joint Computer Conference in San Francisco. This historical event
revealed to the scientific community that a revolution had occurred not
only in computing, but in communication. Engelbart's theories on the organization
and access to information had opened the door for new possibilities of
human thinking, serving as a catalyst for the birth of the personal computer
just four years later at Xerox PARC.
With Douglas Engelbart's oNLine System, the first prototype of the interactive,
networked computer, the dream of Vannevar Bush and his MEMEX had become
a reality. Looking like an information astronaut, wearing his headset
at a control panel and screen, Engelbart was giving the first demonstration
of navigating cyberspace while he communicated via microwave antenna with
his team back at control central at the Stanford Research Center in Menlo
Park. Beneath his fingertips was a keyboard flanked to the left by a special
keypad that allowed character input with one hand, and to the right, the
world's first mouse. On the NLS screen was the first glimpse of interactive
information space, with its groundbreaking hierarchical menus, windows,
and outlines, features that have since evolved into the modern word processor
and essential functionality of the Macintosh and Windows operating systems.
John Cage: inventor, composer, philosopher, conceptual artist,
iconoclast, his work always and eventually led towards theater. His most
famous work was 4’ 33”, which dissolved the boundaries between art and
life, music and noise, sound and silence. The father of the happening,
his collaboration with such artists as Merce Cunningham, Robert Rauschenberg
and Jasper Johns set the stage for experimental electronic theater in
the 1960s.
Merce Cunningham (student of Martha Graham) worked with John Cage for
nearly 50 years, together they forged an integration of music and dance
that was founded on the independence of artistic disciplines in space
and time. Their collaboration involved an agreement in temporal duration,
and then independently they generated both music and dance using chance
procedures (Merce had only to avoid dancer collision).
Variations V was first composed and performed
in 1965 and subsequently toured through Europe (this performance was in
Germany). A classic example of electronic Gesamtkunstwerk, the work was
a collaboration between Cage, Cunningham, musicians Gordon Mumma and David
Tudor, Bell Labs engineers Billy Klüver and Max Mathews (optical
light triggers), visual artists Robert Rauschenberg, Nam June Paik and
Jasper Johns (projections) and the filmmaker Stan Vanderbeek. Derived
from the happening, in which the line between art and life is dissolved,
the work is a surreal juxtaposition of “real-life” movement, objects and
images, in non-synchronous combination using chance technique. Source
material is taken from home movies and tv sitcoms. Music is generated
from taped sounds and live electronic synthesizers. The movement of the
dancers triggers sound and projections as a result of the optical light
sensors.
Reading: John Cage,
"Diary: Audience 1966," A Year From Monday, 1966
"Do you love
the audience? Certainly we do. We show it by getting out of their way."
John Cage
Musician, composer, poet, and philosopher, John Cage's work ranged far
beyond the arbitrary boundaries of the individual arts. Originally from
Los Angeles where he was a student of the inventor of 12-tone music, the
Viennese composer Arnold Schoenberg, Cage's divergence from his musical
teachings eventually brought him to an historic residency at Black Mountain
College in the late 1940s. Here his theatrical experiments with Robert
Rauschenberg, Jasper Johns and Merce Cunningham inspired the 1960s explosion
of performance art, Happenings, and the theater of mixed-means. During
this same time, his adoption of Zen Buddhism also led him to explore the
use of silence and chance to introduce the indeterminate in musical composition.
Through indeterminacy, Cage influenced the dissolution of the fixed, absolute
quality of music (and art), bringing about a more active, participatory
role on the part of the listener. Such infamous compositions as 4'33"
(1953) in which a pianist remains silent at his instrument for
the pre-determined duration of time obligates the audience to listen
exclusively and attentively to the random sounds of its own self-induced
noises. While the work initially instigated frustration and scandal, Cage's
intent was to cause one to reflect on the individual freedom gained from
the composer's "permission" to listen and react to an environment
in which an idea (silence) invented by the artist freely generates new
ones in the minds of the listener. In this two-way exchange between artwork
and audience, Cage suggests utopian visions of a collective wisdom, an
indeterminacy that leads the spectator to realizations not even the artist
might have imagined.
Despite Cage's reference to the future of computer art, the composer made
little use of information technology in a wide ranging and prolific body
of work. Nevertheless, this poetic analysis reveals the philosophical
and aesthetic roots of his view of the nature of our changing relationship
to the artwork, a stance that has had a profound impact on generations
of media artists exploring interactive strategies. Here Cage relishes
a Zen-induced spirit of anarchy that dethrones the modernist artist as
the heroic, all-powerful arbiter of creative expression, proposing instead
a shift towards a post-modern, inclusive art that encourages freedom,
responsibility, participation, and interaction on the part of the viewer.
He prophetically links this position with the need to rethink the servile,
"labor saving" nature of the computer into an agent of participation,
an emissary of receptive experience, opening the minds and ears of the
listener to the world around them, and closing the gap between art and
life.
Roy
Ascott
Roy Ascott is an artist
and theorist whose work has pioneered the creative use of cybernetics,
telecommunications and interactive media . He is a leading figure in the
development of telematics in art, using global networks since 1980.Trained
as a painter, he studied under Victor Pasmore and Richard Hamilton, exhibiting
"change-paintings and analogue structures" extensively in London and Europe
throughout the 1960s. His contribution to art education started with the
radical Grundcourse at Ealing School of Art, London. During the 1970s
he was President of the Ontario College of Art, Toronto; Professor of
Fine Art at Minneapolis College of Art and Design; and Dean of the the
San Francisco Art Institute. From 1986-93 he was Professor for Communications
Theory at the Hochschule fuer angewandte Kunst in Vienna.After sucessfully
developing the first honours degree in Interactive Art at Newport School
of Art, he was appointed as the founding director of CAiiA in the University
of Wales College, Newport in 1994. As Visiting Professor of Science Technology
and Art Research in the School of Computing, University of Plymouth, he
established STAR in 1997.
His work is concerned
with the development of Technoetics: the practice and theory emerging
from the convergence of art, technology and consciousness research. His
interest in the relationship between shamanism and cyberspace led him
to live with the Kuikuru Indians of the Brazilian Mato Grosso in May 1997.He
convenes the annual international conference "Consciousness Reframed:
art and consciousness in the post-biological era".
His
seminal networking projects include 'Terminal Art', USA/UK, 1980; 'La
Plissure du Texte: a planetary fairy tale', Museum of Modern Art, Paris
1984; 'Laboratory Ubiqua', Biennale of Venice, 1986; 'Aspects
of Gaia: digital pathways across the whole earth', Ars Electronica,
Linz 1989: 'Telenoia', V2 Organisation, Holland, 1994. Video documentation
of his work was shown at the Triennale de Milano in 1995. His concept
design for an interactive televator resulted in the permanent installation
Apollo 13 in the
Ars Electronica Centre, Linz.
An influential theorist,
he has published more than one hundred texts in books and journals internationally,
with translations in French, German, Hungarian, Italian, Japanese, Portuguese
and Spanish. A collection of his writings, edited by Edward A Shanken,
is to be published by the University of California Press in 1999. He is
on the editorial boards of Convergence and Digital Creativity in the UK,
Epiphaneia in Italy, and Leonardo Electronic Almanac and Leonardo Journal
in the USA (also responsible for the "Art and Consciousness Research"
and "Panetary Collegium" sections). He was a concept designer of the Ars
Electronica Center in Linz, and has advised the CEC Brussels, Copenhagen
'96, UNESCO, La Caixa Mediateca, Barcelona, Ministry of Culture, Paris,
amongst many international organisations. He has been a Commissioner for
the Venice Biennale, jury member of Prix Ars Electronica and the Interactive
Media Festival, and is currently on the Board of the NTT InterCommunication
Center, Tokyo. He is a member of the Arts Council of England.He lectures
extensively throughout the world.
Reading: Roy Ascott,
"Behavioral Art and the Cybernetic Vision," 1967
"If the cybernetic
spirit constitutes the predominant attitude of the modern era, the computer
is the supreme tool that its technology has produced. Used in conjunction
with synthetic materials it can be expected to open up paths of radical
change and invention in art
The interaction of man and computer
in some creative endeavor, involving the heightening of imaginative thought,
is to be expected." Roy Ascott
Since the 1960s, the British educator, artist and theoretician Roy Ascott
has been one of Europe's most active and outspoken practitioners of the
emerging medium of interactive computer art. Ten years before the personal
computer even came into vogue, Ascott clearly foresaw the imminent approach
of interactivity in the arts, thoughtfully building a conceptual framework
founded in the relationship between the behavioral and process-oriented
characteristics of the avant-garde (Dada, Surrealism, Fluxus, Happenings,
Pop Art, etc.) with the developing science of cybernetics championed by
Norbert Wiener and other scientists.
During the 1980s, Ascott began to present a significant body of art based
in telecommunications technologies, or as he called it, 'telematic art,'
at seminal European exhibitions including "Art, Technology and Computer
Science," the first major show of information art at the Venice Biennale
(1986), and "Aspects of Gaia: Digital Pathways Across the Whole Earth"
at Austria's Ars Electronica (1989), in which the latter project brought
together artists, musicians, and scientists from around the world producing
representations of the earth (Gaia) in dataspace from scientific, artistic,
and mythological perspectives. The fact that Roy Ascott established himself
at this time as the pioneer of networked art takes on greater significance
in light of the explosive interest in Internet art that arose in the following
decade.
Ascott begins his thesis on the "Cybernetic Vision" with the
need for an interactive art freed from having a fixed, absolute value,
as in the modernist ideal of the perfect "object", and thus
unable to be responsive to the viewer. While Ascott has pointed out that
such artists as John Cage explored indeterminacy as a vehicle for breaking
from this tradition in order to find new ways to engage the spectator,
Ascott turned to the computer and the "spirit of cybernetics"
as the primary means for achieving a two-way exchange of feedback between
the viewer and the artwork, not in the doctrinaire sense, but because
he felt it was critical that artists acknowledge information technology
as the most important tool of their age. While these thoughts echo Name
June Paik's musings on the role of the artist in a "cybernated society,"
Acott's vision is not at all ironic but rather utopian in its scope and
embrace of a new medium based on a thriving, living, dynamic exhange between
the human, technology and art.
