Hi:
I work at a company that manufactures touch screens and I=
design touch screen controllers that allow touch screens to be used within=
a PC based system.
Touch screens are made up of two resistive planes for det=
ermining x and y locations (much like a mouse.)
A dedicated microcontroller and an ADC unit are needed to=
properly drive and interpret the readings from the
touch screen.
I have never hacked a touch screen, but from the nature o=
f their construction and the required interplay between
the two planes would suggest that cutting up the screen =
(once removed from the glass) would only damage the it and prevent
P>
and further usefullness.
cheers,
roger

Anyone have any experience 'hacking' resistive sensors li=
ke this? are they
the type of element that can be cut into strips and stil=
l function?
a thin strip wrapped around a 'bot's perimeter could indi=
cate the direction
of a touch or object via the varied resistance...

i bet 'bending' or wrapping the element around a round 'b=
ot interferes with
any useful readings, but multi-facetted perimeters as an=
octagonal or
hexagonal design may be able to incorporate this.
