We are at the beginning of a new wave over say creative powers are being stretched
and we're learning surprising things about how we stand
the world around us exploring the mysteries of the
spoken word.
You know you know you. Lawyers.
Here's the system a system should track very well with one another so I think in
the first go around here we can make all of this misery because these men are
design engineers at Bell Telephone laboratories the research
and development part of the Bell System.
They're about to engage a new breed of computer called graphic one in a dialogue
that will test the ingenuity of both man and machine.
It's a new way of working out abstract problems in the age old medium of drawings
and designs which explains why the technique is called Computer Graphics Now
researchers have an idea for a telephone filter circuit they want to try.
But they need a ready answer for the problem if they do this. What will happen.
They could spend many hours in the workshop building and testing the real thing.
Instead they get directly graphic while cathode ray tube.
The operator talks to the computer with an electronic light pen which does a
precise and easy job of assembling the symbolic parts of the design.
Transformers and automatically position by the pen. Connecting them.
I think be much more readable down the lower right hand.
If they change their plan. No problem.
There's no need to memorize complex for the computer signals the action
when it's ready if the researchers have done a good job of programming what they
want to designed to do the computer is quick to point out any breakdown in their
logic.
The design is complete. Work.
At this stage
or remotely located master computer takes over the job of calculating the
performance of the circuit.
How much change does.
Other color just find the right place in the program make the appropriate change
and would run the whole thing again. Let's make.
One square
and write one square to see what will get the program going through these lines of
consulting a graphic artist
and a Bell Laboratories scientist collaborating on an idea for an experimental
computer made movie
and being able to program something so we know what it's supposed to do
and what I get a response out of we don't know what it's exactly going to do in
terms of images and it's interesting to me
that you say the unexpected things happen because in a sense the computer has done
exactly what you told us to do right there shooting script.
Here's an intricate set of instructions written in one of several programming
languages available. This one is the flicks short for Bell Labs flicks.
This is an excerpt from a B. Flex computer movie showing how the script.
Now a deck of punch cards with all the cues timed in is fed into the computer
winding up as a reel of recorded
onto a real can you possibly can frame the second half first
right now you want to watch one it just halfway between five point six
and leave it perfectly
under computer control now the taped information is converted into a rapidly moving
picture made up of a fine mosaic of points of varying light intensity synchronized
movie camera automatically photographs the fast moving images as they are plotted
and drawn on the face of the cathode ray tube.
Who do I want to reach out to this technology.
I want to incorporate this technology into into my eyes
and have the two mics together first with me as an idea.
Some place where it Station and write a movie
or maybe even pick up a telephone eventually and write a movie.
Creating unique visual effects movies can be used to show phenomena.
We can't directly see this film describes the motion of the communications
satellite by studying it.
Scientists can obtain new insight into the satellite stabilizing system only a man
orbiting alongside could observe it the same way
experimenters in visual perception are using computers to create weird random
patterns that never occur in real life.
To find out what
and how people see these patterns to show these patterns curiously reminiscent of
the point of the nineteenth century artists whose beautifully integrated paintings
are formed by countless computer like dots
and dashes the artist has an incredibly methodical technique
that produced only a dozen or so. Paintings in his lifetime. Today.
Researchers are generating
that many in a single day the
shape and texture of perceived objects of studies
that look deep into the future of communications
when we learn to separate the relevant from irrelevant in visual information will
be on the way to sending three dimensional color picture messages over ordinary
telephone lines.
And then we found that when you get back far enough.
Not only do the small pictures disappear because you're not close enough to see
them individually and the big picture comes across.
But if you get even further back then the picture takes on a continuous tone
quality is all
or a photograph rather than being a very crude computer generated special a
quantized thing. One of the interesting things to me was
that you can drop quite a distinguishable picture just an eleven by eleven array of
black spots
and white spots the
entire musical score accompanying list film was composed on a computer
that can produce nearly endless variations of some were interested in finding
better ways of describing complicated.
Sounds like however very complicated.
Music is simpler some of the that's what we're using here is bad music in
terms of a bad.
And also the years mistakenly can find out a great deal by studying the simpler
sound
programming as far as like composing for conventional musical instruments.
Except
that notes are a place by numbers the computer converts these numbers into impulses
that cause sound waves to come directly from a loud speaker
and what
actually happens when we hear sound.
We know that the membrane of the inner ear changes sound waves and auto sensations.
But until recently. No one had seen the whole inner ear in action
when sound waves strike the membrane it makes thousands of microscopic movements to
second only by computer could they be calculated
and for the first time Torelli describe it takes several minutes of this motion to
draw the simple sound of yet since the model of the inner ear is being
expressed back to magically they can be pictured in different waves in this three
D.
Version the membrane is given a spiral shape recoiling as it receives shocks from simulated
sound waves.
How size and so I stand our problems are showing three dimensional moves
and we show these movies up in Boston.
People up there are quite interested excited in what they saw and yes I suppose
that as an educational tool it is very good it allows people to see things which
only mathematicians can see before
and in fact the people who seem most interesting work and medical doctors
and people like on.
Our Human Stain Leming least so simple is
a very complicated process no one fully understand me me
when
I read those words were spoken by a digital computer program to simulate a
speaking machine much of what we know about voice
and speech is stored in the computer's memory from there we can experiment with
more advanced ideas in areas that are still take stress.
How do we always seem to know just which parts of spoken words to emphasize
let's try to sensitize attempting to.
Scientists can only begin to explain how we speak.
We stress words without thinking. Giving them fine shadings of pitch and intensity.
Are you really glad if you can change the stress
by tried. When phonetic symbols are said to the simplest.
It combines them into intelligible speech.
While there is more interaction on it.
Let's see if we can improve the why don't we look at the pitch.
I think I'll try to make inflection on black a little bit from the.
That that's a fact and improve
that black the
art of computer graphics is only in its infancy.
Yet it is already stimulating creative thought in far out areas where research is
likely to get complex and unwieldy.
It offers not only the means to quicken the pace of discovery
but an ideal way of communicating what we may discover it.
