I know they have something to do with tilting the 3DS, but what do each specifically do? Just curious.

Thanks!

From:Wikipedia | #002
A gyroscope is a device for measuring or maintaining orientation, based on the principles of conservation of angular momentum.[1] A mechanical gyroscope is essentially a spinning wheel or disk whose axle is free to take any orientation. This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscope's high rate of spin. Since external torque is minimized by mounting the device in gimbals, its orientation remains nearly fixed, regardless of any motion of the platform on which it is mounted.

Gyroscopes based on other operating principles also exist, such as the electronic, microchip-packaged MEMS gyroscope devices found in consumer electronic devices, solid state ring laser and fibre optic gyroscopes, and the extremely sensitive quantum gyroscope.

Applications of gyroscopes include navigation (INS) when magnetic compasses do not work (as in the Hubble telescope) or are not precise enough (as in ICBMs) or for the stabilization of flying vehicles like radio-controlled helicopters or UAVs. Due to higher precision, gyroscopes are also used to maintain direction in tunnel mining.[2]


Thanks, that link really helped. I'm glad that I know I can use a 3DS for staying oriented while mining in a tunnel.

Next time don't be a smart ass and actually try to help. K thanks.

^ Lol, sorry but that was funny about mining in a tunnel.

The accelerometer measures the speed or momentum if you will with which you tilt the system. The gyroscope measures which way you tilt the system. This allows games to do things like (as a very simple example) make things slide left or right with realistic physical reactions to the speed and direction you tilt the system.

Haha, thanks for the serious answer. It helped much more than the previous one.

What you don't understand the wikipedia entry? You should try taking a physics course then.

Assuming they handle all 6 axes (and it would be silly if Nintendo didn't do that), then coupled with the cameras and a bit of clever programming, you could have absolute spatial awareness for the 3DS.

There HAS to be some sort of funky gameplay waiting to take advantage of such a thing in a portable package.

I actually thought this post was pretty comical after visiting one of the links. Never knew that link existed. Will be using it in the future as well.

Not to sound like an ass, but TC did you try to research either term before asking here? Just a question.

Strickly speaking, an accelerometer can't measure speed, it can only measure acceleration, both it's magnitude and direction. This means it detects force imbalances applied to system (F=ma, all acceleration is due to an unbalanced force). So in otherwords it can tell when you move the system, how hard you pull it or push it, and in what direction. Of course, it's only so sensitive, so a very weak force might go undetected.
