+This
particular
Rear
Diffused
Illumination
Multi‐touch
design
used
a
cabinet
made
of
core‐ten
steel
that
had
recessed
cabinet
cooling
fans
and
access
panel
on
the
rear
vertical
wall.

The
touch
surface
was
made
of
1⁄2
inch
polycarbonate
with
an
adhesive
projection
film
applied
to
the
underside
of
the
touch
surface
that
acted
as
a
diffuser
for
the
projector.

A
TUIO
Client
Application
is
projected
from
the
underside
of
the
touch
surface
onto
this
diffuser.

This
is
the
image
that
the
user
will
interact
with.
Depending
on
the
diffuser,
this
method
can
also
detect
hover
and
objects
placed
on
the
surface.


+
+In
addition,
infrared
light
is
also
shined
at
the
diffuser
from
below
the
touch
surface
via
a
series
of
IR
LED
arrays.
When
an
object
touches
the
surface
it
reflects
more
light
than
the
diffuser
or
objects
in
the
background.

This
extra
light
is
then
sensed
by
a
simple
web
cam,
which
feeds
the
TUIO
Tracker
Application.

+My
personal
response
to
this
project
is
one
that
highlights
my
great
appreciation
for
the
manner
in
which
all
members
contributed
to
the
final
conception
of
the
exhibition,
even
when
it
seemed
that
we
may
never
see
the
project
come
to
fruition.
It
was
the
delegation
of
tasks
within
a
group
dynamic
that
allowed
each
member
to
contribute
significantly.
By
using
each
person’s
skills
to
their
fullest
potential,
while
at
the
same
time
being
aware
of
the
overall
outcome,
everyone
was
able
to
apply
themselves
as
well
as
learn
from
this
collaborative
experience.

\section{Wiremap}
-The Wiremap has lots of string.
+The
Wiremap
is
an
innovative
projection
technique
that
builds
a
real
and
interactive
3d
image
by
manipulating
light
from
a
projector.

The
projector
throws
its
beam
on
an
array
of
vertical
wires
(the
number
of
wires
depends
on
your
desired
resolution).
From
the
focal
point
of
the
projector’s
lense,
all
the
wires
are
evenly
spaced
from
one
another.
However,
due
to
the
randomized
dimension
of
depth,
from
any
other
perspective,
the
wires
create
a
3‐D
map
of
cyberspace.
The
result
is
a
projection
screen
that
allows
for
the
visualization
of
a
2‐D
image
into
a
3‐D
object
whose
source
is
the
light
 of
a
projector.
An
object
can
move
around
and
change
in
color
or
size
according
to
whatever
is
delegated
by
the
programmer
in
Processing.



+
+Our
specific
map
was
made
using
mason’s
string,
3⁄4
inch
plywood
and
some hardware
for
the
weighting
down
each
string
and
for
hanging
the
entire
wiremap
in space.
Our
map
used
256
strings
that
are
placed
in
a
randomized
dimension
of
depth through
256
holes
on
both
upper
and
lower
alignment
boards.
These
strings
are
secured
through
the
alignment
boards
at
the
top
and
bottom
with
hardware,
with
the
bottom
hardware
also
providing
an
element
of
weight
to
each
individual
string
to
keep
it
taught.
A
calibration
stage
must
be
done
after
initial
setup
of
the
wiremap,
this
process
aligns
the
top
and
bottom
boards
so
that
they
are
parallel
with
one
another.
Also,
the
focal
point
of
the
projector
must
be
properly
placed
in
line
with
the
wiremap
so
that
each
of
the
256
strings
contains
only
one
pixel
width
on
its
projection
surface.
