2.1
How
infrared
touchscreen
works
IRTOUHC
infrared
touchscreen
uses
a
kind
of
technology
based
on
optical
blocking
induction
detection
and
location
system.
The
infrared
touchscreen
is
surrounded
by
closed
arrangement
of
infrared
emission
and
receiver
tube
arrays.
The
infrared
emission
tubes
emit
infrared
light
so
a
dense
light
net
is
formed
on
the
glass
surface.
The
infrared
receiver
tubes
receive
infrared
light
emitted
by
the
corresponding
infrared
emission
tubes.
When
user
touches
the
glass
surface,
the
infrared
emit
‐
receive
light
path
is
blocked,
which
can
be
used
to
calculate
the
location
of
the
touching
point.
