The technology to do a true 1:1 game is there. The main problem is that it's really hard to do. Wii we see a true 1:1 game on Wii? probably not. Devs are not going to bother themselves in taking so much time to do that. Games like Dragon Quest Swords and Dynasty Warriors don't do that because it is easier and faster to make games without actually fully manipulating a sword in real-time 3D space. Maybe Nintendo's next console will make it easier. But to say it's not possible on Wii is pretty pessimistic.

Its not pessimistic, its correct......as several users have already agreed with me on. you CANNOT do true 1:1 movement with the wii, its just not got the appropriate sensors or peripherals for it to be true 1:1.

Take a look at the technique used behind figuring out 3D position and also 3D orientation because it cannot be done truely on the wii.....sure the programs can attempt to predict where the wiimote is relative to where it started but it can only predict, which makes 3D 1:1 tracking a minefield of unknown variables which cannot be calculated since they are constants based on the initial conditions at time t=0.

Position from accelration:

velocity = integral of acceleration......which is either a constant or a time variable value.....plus the initial velocity (not known).

position = integral of velocity .... which again is either a constant or a time variable (including the unknown initial velocity integrated)......plus the initial position (not known)...

that is a basic explanation of position calculated from acceleration.

The 3D position is calculated based on triangulating (or trilateration) from FOUR reference points, the wii does not have any reference points....maybe the bluetooth signal is one...but that isnt enough to calculate position, it can figure distance from the base station...which is no use in 3D tracking.

The sensor bar is there to figure out angle relative to the bar for using the onscreen pointer, this is impractical for use as a 3D tracker, and only has 2 reference points.

Hopefully i wont have to explain this again, the wii cannot replicate true 1:1 motion....its a total myth!!!

The games mentioned aren't true 1:1 in the eyes of mrvanx. It doesn't track where the wiimote is in relation to your body and is spotty when recognizing a normal movement compared to a swing.

With a bit of ingenuity, a group of developers could get close enough for everyone to have the ultimate control they desire without having true 1:1. I think it's fun to dream about, but without a full body suit and large list of accessories, 1:1 movement in video games isn't going to happen. It is a moot point though because the Wii controls are infinitly closer to 1:1 just the way they are. In actuality, 1:1 isn't what the consumer REALLY wants anyway. A regular person who plays video games isn't trained in the use of one weapon, much less the minimum of 6 we've come to expect. Also, true 1:1 would take acceleration into account of force and beating someone with a bat would wear you out just as much as real life. Finally, a solid object in a video game is nonexistant in real life causing huge problems with the different physics involved.

Back to the topic. Bushido Blade 2 had a first person gameplay option. I think a first person melee game would work well on the wii, but would need some fairly simple controls and motion sensing to pull it off without being frustrating. Let's face it, most of us will never know the in's and out's of using a katana....

Thankyou for understanding my point sir :)

Ive been playing about trying to get meaninful data into Matlab from one of the wii-motes (over bluetooth naturally) and the various accelerometers inside arent all calibrated identically so you would need to build into a program calibrating the offset for the acceleration before starting the game, id LOVE to get hold of the wii dev kit! :D

If you read and study into what is required for full acurate 3D tracking youl know that since there is NOT a fixed reference point to satisfy the two unknowns in the Integration of acceleration (from the sensors) into speed, then again into position....then you cannot calculate 3D position (and in turn 1:1 movement) accuratly.

Do the maths then you will see there are two unknown values which must be known to calculate the position and speed at time t=0.

Next for 3D trilateration/triangulation you need 4 points of reference and the best the wiimote could hope for is two, both of which are impractical since they are on both ends of the sensor bar......and the wiimote must be pointing the ir sensor at them.

The games which MIMMICK 1:1 tracking, if you test them out, do a semi-decent job with expected movements but a quick jerk of the pad and the baseball bat is swung or the bowling ball is thrown.....not 1:1 movement.

The Wii does a VERY good job of tracking movement but it isnt and never will be 1:1.

See my post in this topic: http://uk.gamespot.com/forums/show_msgs.php?board_id=909104101&topic_id=25889013

Its VERY unlikely that the wii can reliably track 1:1 movement with the wiimote ...

....HOWEVER....

.. a bit of fancy coding could get pretty close but a high number of different movements would need to be modelled during development of the game which might lead to lazy developers abandoning it. Its likely the game could be made but id forsee only Nintendo having the effort to pull it off, sure tilt and acceleration is a decent ammount of input but to truely track 1:1 a sword fighting game it would be alot of hard work to realise it.

Wow im actually quite alarmed by the ease WEP can be cracked (just read through a few articles).......and the gits that live round near my house would probably try cracking a few networks if they had the chance.

Cant say im particularly bothered about not going online with my DS since im REALLY bored of the games online once theyve been swamped by people constantly using the various bugs/traps in the games to win. (such as snaking and alt-spamming etc..)

I SHALL be switching to WPA asap!

ummm its not going to make that much of a difference imo, they already put in new heatsinks even with the 90nm hdmi 360's out on the market right now. Link: http://www.joystiq.com/2007/08/10/spot-the-hdmi-enabled-xbox-360-premium-at-retail/

i am not an engineer but my understanding is that 65nm isnt that big of a deal its more of cost saving measure the more singinificant step the adding of a new heatsink has already been taken.

Tactis

The reduced die size provided by the 65nm tech is obviously cheaper to make and therefor SHOULD be cheaper to buy....but also using the smaller track width means a lower power requirement and thus less heat given off by the chip...so in theory it should make the system more stable, but who knows :D

Hey all, ive had my elite for over a week now and its GREAT! You cant beat having a 4 way game of R6 Vegas online with the headsets going hehe.

Crackdown is also a hoot when playing a coop, PES6 yet again is a good game online aswell as offline.

Only foible i have is that the xbox is failing to sign in to msn messenger, it WAS working but decided to stop working....is this a common thing? I have triple checked my password etc....??

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!!!
