The Physics of the Wii Remote
The Wii remote uses both ______________ and ______________ waves to
measure your motion and position when playing a game.
The sensor bar only communicates with the ___________________ using
_________________ waves. The bar has one LED at each end of the bar. Through
the use of _____________________, the ___________________ knows
________________ and _________________ compared to the sensor bar.
There are three internal instruments called ____________________ that detect
_________________ and __________________ of the remote. One measures up
and down, another one measures left and right, and the final one measures
____________ and ____________.
By using the information from the sensor bar and the ________________, the Wii
remote knows both its position and motion at any point in time. The Wii remote
must communicate with the Wii in order to play the game. The remote
communicates through the use of _______________ technology, which uses
____________________ waves.
There are several reasons why ________________ technology is used instead of
infrared waves. Infrared technology is ________________________, which means
you must physically point the remote at the receiver. This is how most TV remotes
work. Bluetooth does not need to point in any specific direction, and is less likely
to have ____________________ with other sources. Another main benefit of
Bluetooth is that communication is ___________________ and
_____________________, so once a communication link is established,
communication happens instantaneously between the remote and the console.
One final benefit is that Bluetooth technology uses less _____________, which
will not drain ____________ as quickly as an infrared remote would.
