This
work
tries
to
introduce
a
popular
game
console,
Nintendo
Wii
Remote,
which
is
easy
and
intui<ve
to
use
for
the
interac<ons
with
the
computer
in
the
above
environment.
The
Wii
Remote
naviga<ons
were
implemented
for
a
constella<on
observa<on
system,
a
stereoscopic
molecular
dynamics,
and
the
stereoscopic
Google
Earth.

detects

that
it

We
need
both

to

to
determine
the
