Pen Sense
Pen Sense consists of six Sharpie Chisel
markers, with the first five Sharpies
gaffed with an inbuilt transmitter (the
black Sharpie is ungaffed).
Pen Sense can be programmed to
generate notifications through either
movement or the presence (or removal)
of a magnetic field.
As the performer simply needs to know,
which color the spectator has selected,
Notifier displays the image of the
corresponding marker, along with an
English description of the color.
