Question... Why can't the Wii do 1:1 movement in 3d space? Or... Can it?

Heres my qestion. From what I have seen the Wiimote can do 3 specific things...

Sense tilt. Sense motion. And become a pointer with the sensor bar.

My question is. Why can't it, or can it (and it just hasnt been done) do 1:1 . Take sword fighting for instance.

Yes one of the problems with sword fighting is the force feedback. You wouldnt really get that "force" when you met with the other guys sword on the screen. However... ignoring this problem.. I am wondering can the Wiimote even do 1:1 in a 3d space?

Im not trying to say it cant, Id like to know. Obviously we havnt seen it do anything but sense tilt and motion.

I will compare what I am asking to Motion Capture. Motion Capture allows for capturing the movement of objects in a 3d space... can the Wiimote do this? will we see a lightsaber game that mimicks our movements? Or are we stuck with games that just have predesposed manuvers for our movement. IE Tilting up to down, swings down, and tilting down to up swings up. If you see what im getting at.

As far as I know, the wiimote can't tell where in 3rd space it is in. So the 1:1 sword fight in a way ain't possible, but they can use the other things it can do to get as close as it can. Take Wii boxing or baseball. the bat/gloe seemed to folow your hands almost the same except for certain occasions and stuff, so I'm expecting to see similar stuff to that. So I"m thinking the 1:1 sword fighting will be more like a "illusion" so to say to make it look like your doing 1:1. So will see games making it look like your doing that,when you really aren't actually.

I'm not exactly sure if what I say is truly accurate, but if some one can say other wise go ahead.

Hmmm I know what you mean, it seems like the only way that would work if it was being used as a pointer. To completely mimic moves in the same way would require infared emitters all across the room, which is of course not practical.

I don't think the Wiimote can do that, but it does have very fine tuned motion detection. I suppose if one had first used the senser bar to create a reference point for the Wiimote, the wii could then detect how close or how far you are from that point in 3d space to allow perfect movement reproduction...

I geuss we will have to see what developers come up with. I don't think the full potential of this device has been fully realized yet.

Yeah, the best example for 1:1 motion I can think of is the baseball game in Wii Sports. Before you actually swing, you can move the bat however you want. But as soon as you move the remote quickly enough, the game is programmed to start the swinging animation.

My guess is that there is a programming difficulty with allowing true 1:1 movement in a situation like that. As it is now, the game only needs to do some simple calculations since the swing animation is determined before the ball hits the bat. But if 1:1 movement were used, the game would have to simulate real-time physics extremely accurately so that the ball would realistally bounce off the bat, considering the speed of the ball and the speed and angle of the bat.

The same could be applied to all other 1:1 movements. It's a completely different type of programming than developers have had to use in the past. But with predetermined animations, it's essentially the same (programming-wise) as pressing a button.

I suppose if one had first used the senser bar to create a reference point for the Wiimote, the wii could then detect how close or how far you are from that point in 3d space to allow perfect movement reproduction...l8bitz

Warioware uses this technique in a few of the minigames. In one, you have to insert dentures into a mouth. The floating dentures move closer or farther from the mouth as you move the remote towards or away from the TV. You can tell that this is done through the sensor bar and not through the remote's internal motion sensing.

Red Steel also does this in sniping mode. When you press the A button to aim, your current distance is used as a reference point, so that when you move the remote closer, the scope zooms in.

The difficulty isn't in programming it. The difficulty is in making it fun and immersive from a gameplay perspective.CodeMunki

Then why wouldn't Wii Sports use 1:1 motion in any of the games? All of them would work well with it.

Neither of those actually relies on 1:1 for the gameplay, though. In both, the swinging animation is predetermined. You can simply jiggle the remote and your character will swing.

But keep in mind they were only tech demos, and that 1:1 really wouldn't add too much in terms of gameplay.hamstergeddon

This I agree with. And I still think that 1:1 wasn't used because it would be too much work to put into a tech demo that was made simply to illustrate some of the possibilities of the remote.

Wii sports is definatly the biggest illusion out there. People dont get you can just move the remote fast in any direction and get the same result

I doubt that the wiimote can do full 3D 1:1 tracking, you need four reference points to triangulate in 3d space, if you eliminate the possible position behind the sensor bar then you would only need 3. But still the sensor bar only provides a reference for the pointer mechanism (the wiimote detects the LEDs on the front of the sensor bar).

You could try to performe some movement tracking by taking into account the acceleration and tilt of the wiimote but again for decent tracking you need a reference point to fill in the initial condition (the missing variable when you integrate from acceleration to velocity then to displacment).

There is most likely some fancy programming involved which once a certain threshold of acceleration is breached the 'bat' is swung or the sword is thrown etc.... so the effect of mimicking the movement is still possible just not in the standard triangulation/trilateration way, quite a few assumptions and innacuracies would be introduced not that are necessarily noticeable to the end user.

Either way you look at it its doubtfull that the wiimote can track 1:1 but the damn thing still rocks!!!
