DualPanto
is
a
haptic
device
that
enables
blind
users
to
track
moving
objects
while
acting
in
a
virtual
world.
As
shown
in
above
figure
(b),
the
device
features
two
handles.
Users
interact
with
DualPanto
by
actively
moving
the
me
handle
with
one
hand
and
passively
holding
on
to
the
it
handle
with
the
other.
DualPanto
applications
generally
use
the
me
handle
to
represent
the
user’s
avatar
in
the
virtual
world
and
the
it
handle
to
represent
some
other
moving
entity,
such
as
the
opponent
in
a
soccer
game.
