Put
yourself in my shoes and see the world from my perspective.
Pictured above is an old communications antenna array on copper-lined helmet,
not presently used. Now I use the ``visualfilter'' (pictured below).
Through the VisualFilter,
I perceive my surroundings by "viewing" rather than seeing,
and this also means that another person can "view" the world exactly as I do.
Closing the loop in this way (e.g. using the
visual filter explained below) enables me to record
exactly what I experience, as opposed to merely putting a camera
on my head (above picture)
in the style of Letterman, 60 Minutes, or the like,
where the camera would not necessarily record exactly what the viewer
was looking at.
Science fiction writers have
wondered what it would be like if we
could tap into the visual path from eye to brain, routing
the visual information elsewhere.
I doubt this is possible using today's technology,
but using this camera system with radio communications,
which I call ``NetCam''
I can presently send my visual field
anywhere in the world, using the internet as a communications medium.
NetCam together with the World Wide Web,
means that others can see the world from my perspective.
Go ahead:
put yourself in my shoes -- see the world
from my point of view.
If you have a better net connection, and a faster computer, you can
see more of my point of view.

If you have a very slow net connection, you may want to limit your view to
a single still image,
or wait patiently for the sequence of images or
avoid this site altogether.
The visual filter
Sending visual information from my head-mounted cameras
to one or more remote processors
(like some SGI Reality Engines on the Internet)
and then receiving a processed version of the visual information back
at my head mounted display,
gives rise to what I call the
`Visual Filter'.
While I can't put a Reality Engine in my backpack, I can still pipe
my visual world through one or more such computers and get the same
effect.
A science fiction writer might envision
implanting a computer anywhere in the world between
the eye and the brain, but this is a long way off.
Right now I'll live with my bulky communications equipment.
Simple processing like turning the image
upside-down (like the upside-down prisms that people used to use to see
if someone could learn to live in an upside-down world) would be possible,
but of course there are far more interesting possibilities.
It's fun being a cyborg.
leading a somewhat nomadic lifestyle.
Applications of VisualFilter and NetCam:
There are other cameras on the Web
but as far as I know,
right now, this is the only
wearable one (please let me
know (mann@eecg.toronto.edu)
if you find another wearable
WebCam
somewhere, or if you are interested
in building one).
Privacy issues of NetCam and other video cameras:
NetCam has raised some interesting privacy issues. Rather than limit
the discussion to privacy
issues of NetCam alone, let us look at the
big picture -- at the broader societal issues surrounding visual
privacy.
NetCam has allowed us to see privacy in a different
light, and to reconsider the notion of visual privacy. In
particular, consider
privacy issues of wearable cameras (like NetCam)
versus surveillance cameras
(like this ceiling dome of wine-dark opacity).
Many advocates of surveillance have dismissed the
Orwellian aspects of video surveillance,
by suggesting that it just makes
the world more like a small town, but if we
compare surveillance and small towns on a `symmetry axis'
we see that they are quite different. In fact, wearable cameras
are more apt to make the world like a small town than surveillance
cameras.
What is and is not a violation of privacy? Perhaps the principle
of "self ownership" could
serve as a guide to answering this question.
Unfortunately, video surveillance is growing out
of control, and one almost wonders if privacy is
a lost cause. If it is a lost cause, perhaps
we can at least
have
a little bit of fairness on the Surveillance Superhighway.
The concept of
privacy in cyberspace
is quite real
and achievable, but in physical space, perhaps symmetry
is a more attainable goal.
Other diversions that may appear from time to time,
in place of, or in addition to NetCam
to further delay my thesis:
- A radio controlled car with a small camera inside it (e.g. take a tour
of my office or the hallway)
- Self-destructing comics; my life is a comic book, when I put text on
each picture in a sequence of images. Comics self-destruct by virtue
of the circular buffer effect. Best highlights saved...
- Highlights of my life; various experiences I'd like to share;
fading memories, that get compressed more and more as they become
older and older, simulating the way the brain forgets things.
