DS stuff most likely.
GDC is the most likely candidate for pre-E3 Revolution news.

you could hold the A button which makes link Grab a door or block.
then pull the controller towards you. this could then make the controller have rumble and force feedback so it feels resistance till you let go of the a button when link would then let go as well.
makes sense.
You are right, actually. Flywheels are used to orient satelites in space.johns all like said:ok, the 3 gyro scopes sounds cool, but can anyone please explain the physics behind this? if this were to work, how exactly could it resist motion? vibration and resistence to motion are completely different. if you were to draw a FBD of how this would work, i think you'd learn it wont. this is like saying that given 3 large spinning gyroscopes, you could theoretically spin a space ship without having to apply any thrust. if this has been documented as happening, could someone please point this out? ...or i'm missing the point completely.
A flywheel is a heavy rotating disk used as a repository for angular momentum. Flywheels resist changes in their rotation speed, which helps steady the rotation of the shaft when an uneven torque is exerted on it by its power source such as a piston-based, (reciprocating) engine, or when the load placed on it is intermittent (such as a piston-based pump). Flywheels can also be used by small motors to store up energy over a long period of time and then release it over a shorter period of time, temporarily magnifying its power output for that brief period. Recently, flywheels have become the subject of extensive research as power storage devices; see flywheel energy storage.
A momentum wheel is a type of flywheel useful in satellite pointing operations, in which the flywheels are used to point the satellite's instruments in the correct directions without the use of thrusters.
The kinetic energy stored in a rotating flywheel is
E = 1/2 * I * omega^2
where I is the moment of inertia of the mass about the center of rotation and ω (omega) is the angular velocity in radian units. A flywheel is more effective when its inertia is larger, as when its mass is located farther from the center of rotation either due to a more massive rim or due to a larger diameter. Note the similarity of the above formula to the kinetic energy formula E = mv2/2, where linear velocity v is comparable to the rotational velocity, and the mass is comparable to the rotational inertia.
A gyroscope flywheel will roll or resist about the output axis depending upon whether the output gimbals are of a free- or fixed- configuration.

A control moment gyroscope (CMG) is an example of a fixed-ouput-gimbal device that is used on spacecraft to hold or maintain a desired attitude angle or pointing direction using the gyroscopic resistance force.

For a more thorough explenation, I'm just going to quote the Wikipedia:

Interesting thing to note is that Matt Cassamassina hasn't updated IGNCube or IGNRev. While this is not necessarily surprising, it is an interesting coincidence.PhoenixDark said:DS stuff most likely.

And like I said before, there is a decent chance that the revmote already has a flywheel in it for rumble. An off balanced flywheel is how the GCN controller rumble works, I believe. Having on-balanced flywheels in there is not that big of a leap.
antipode said:Doesn't it just use vibrating motors, per Immersion's patents?
A flywheel is something different - it's an object spinning with enough momentum that you can use it to resist a rotation about its axis, or use the stored energy as a battery.
From one of the two patents Immersion sued over. Eccentric, as in not centric; unbalanced.a rotating-mass actuator including a shaft and an eccentric mass mounted on said shaft, said rotating-mass actuator operative to impart a rotating vector force upon said user, said rotating vector force creating a tactile sensation upon said user that is perceived by said user as one of a vibration, an impulse, and a series of impulses depending upon a speed of rotation and a number of rotations of said mass, said rotating mass actuator capable of providing all of said vibration, impulse, and series of impulses, said speed of rotation and said number of rotations being controlled by a profile of an activating signal provided to said rotating-mass actuator, said activating signal causing said tactile sensation to have a frequency that varies over the duration of said tactile sensation; and
Papi said:These here http://www.paragonmartialarts.co.uk/powerballs.htm use flywheels, apparently. Hmmm. *strokes chin*
I understand the concept. But you're right, I might have the amount of speed and energy needed for even subtle resistance wrong.antipode said:I'm still not sure if you understand what the concept of a flywheel is, Snow.
No, I don't think so. If you want it to actually resist motion in a useful way to games, you would have to build up angular momentum first, by revving up a flywheel, or something similar. What you're describing is basically how those powerballs work. Which do resist motion eventually, but not really in a way you could utilize in games.LUNA said:Won't battery issues be solved if yo think that everytime you are "feeling a forcefeedback" comming from a Gyro in fact you are giving energy to the Gyro (making it turn faster).

Something like what is in this patent sounds closer to what might be usable. It seems to use a lot of bateries and space though, but you could get away with much smaller resistance in the Revmote.jkooXL said:http://www.buytelescopes.com/product.asp?pid=1824
My dad has these, they are binoculars with image stablization which I am pretty sure is the same technology you are talking about. You press a little button and instantly the thing just SOLIDIFIES itself in space, no shakiness when looking through the binoculars, and its very hard to rotate the thing in your hand, it just wants to stay absolutely still. Very very cool, and would be amazing if implemented into the Revmote. However look at that price...

And yes, I'm bored, and realize that my ideas probably still violate some basic tenets of physics.![]()

Safe to say this thread has jumped the shark. Feel free to keep bumped on your own, but the sticky is now revoked.
