How does an accelerometer for Nintendo Wii work?

Answer 1

The accelerometer in a Nintendo Wii controller basically detects a 3-axis range of movement by using a digital accelerometer. This accelerometer detects movement in these three particular axis by sensing small voltage changes that occur in the accelerometer during movement in each of the three axis. Google "how does an accelerometer work" and you will get a little better understanding of how this works. The one axis, however, that the accelerometer in the Wii remote does not detect is rotation on a flat X plane. So in other words if I hold the Wii remote flat, parallel to the ground, and begin to rotate it left and right while still keeping the remote flat to the ground the accelerometer would not detect that movement. This is why the Wii has the sensor bar with the two emitting IR LEDs in it. The Wii remote has an infrared camera on it and when it sees the IR LEDs on the sensor bar it is able to provide tracking data to the console and track the X plane movement of the remote. Hope this somewhat answers your question! Thanks.

Answer 2

the black sensor on the remote, links with the on that you put on your tv, these sensors send and pick up commands

ie: controler-tv motion

tv-controler vibation and sound

hope this helps
