Identification
For
special
populations,
such
as
people
with
thin
eyebrows
or
with
no
eyebrows,
the
system
need
1-60
seconds
to
detect,
if
the
green
light
turns
on
when
open
eyes
and
green
light
turns
off
when
close
eyes,
it
means
the
identification
is
successful.
The
product
may
not
be
able
to
identify
some
old
age
people
(above
60
years
old
and
young
age
people
(below
15
years
old,
also
can’t
identify
people
who
have
only
one
eye
(the
system
is
designed
based
on
two
eyes.
Old
people
can
be
detected
if
they
are
in
good
body
condition,
big
scar
around
the
eyes
cannot
be
identified
as
well.
For
some
rare
people,
if
can’t
be
identified
by
the
system
after
1
minute,
we
suggest
not
use
this
product.
If
they
still
hope
to
buy
it,
they
can
provide
the
front
face
photos
to
us.
We
can
make
special
one
for
them,
but
need
additional
cost
and
time.
Wear
Glasses
or
Sunglasses
or
Contact
lens
For
drivers
who
wear
glasses
or
sunglasses
or
Contact
lens,
the
system
can
also
detect.
If
they
wear
the
glasses
with
frame,
in
case
the
frame
ward
off
driver’s
eyes,
better
to
put
the
glasses
a
little
bit
more
up
on
the
nose,
or
install
the
host
more
lower
(the
position
is
lower
if
installing
inside
the
dash
board,
we
suggest
to
wear
the
glasses
without
frame.
For
people
who
wear
deep
color
sunglasses,
they
can
install
the
host
closer,
we
suggest
wear
bigger
sunglasses.
For
contact
lens,
without
any
affection.
