Do you have any evidence to support this? Otherwise this is surely just an opinion

Anyway the thread seems to be going way off topic to an analysis of the controllers of various consoles over the last 20 years which ultimately proves nothing and results in flame war (which I am guilty of too). Going back to the OP the answer is no Nintendo cannot sue as what matters is that the tech in the MOVE is different to the wiimote and the obvious similarities aside this is all that matters. Surely the fact that the remote operates with the PS eye indictaes taht they are not exactly the same.

Actually "You fail like no else does" is valid for your whole topic:

Sony motion controller, 2004: http://www.youtube.com/watch?v=JbSzmRt7HhQ

very few games bother with six axis tbh and even when they do the feature is optional and 90% of people probably dont use it

"potentiometer-based analog stick"

It happens the all mighty craptacular "analog stick" from Atari 5200 was nothing else than a directional stick programmed with some more standart pin points, not really user-free chosen angle and direction.

As for the Vectrex, yes it seems I was wrong, but I fail to see whether the games of it make use of the "analog" technology has the games seems to be controlled in the regular 2 axis scheme.

And the fact that vectrex is whether a console or some kind of hybrid computer just designed for games is arguable. It clearly doesn't fit completely the home console category which are discusing, yet is not fair to consider it a computer too, ok.

@ damnyou all

You're funny to infinite levels and that video shows a toy being recognized by the camera, that's a famous video that shows nothing similar to the Wii controls, which was what Sony presented.

but there are some.  and there are games that are sixaxis only like supper rub a dub.  Folklore had a mandatory and welldone use of the sixaxis.  So I do agree that it's few games and yes 90% don't use it.  But just like not all wii games use motion controls either.  It's just something that is there.  I guess I could have just said you should see how many adults play wii sports or mario kart wii, but I was bringing up that the ps3 had motion controls from the day it was launched. 

Please allow me to highlight the most important part of your post:

I have nothing to add.

@ wonktonodi and Cloudphoenix and pingu

The sixaxis use is not like the motion control itself seen in a wii game, much more like and additive for the gameplay which could be done by mapping it to buttons.

The games that support motion on the sixaxis, are just for the sake of it.

Whether adults would like to play or not motion controled games on PS3 is yet to be seen, imo.

  Good, it means you're out of arguments and you're finally leaving the thread. Thanks for posting anyway.

See you around. Peace.

Bamboleo if Nintendo can sue they will
The world works with innovation taking something and working it into something else. The move is a different type of motion controller from the wii mote and nun chuck just and it's different from sixaxis or the balance board or natal.
Nintendo is not the creators of all that is video gaming.
Sony is not the thief or copier of all that is video gaming.
The big answer to your question imitation is not something you can sue over. Copyright infringement is.

I don't know how you came to that conclusion from the technical document you've linked to. I quote from it:

Analog Direction Inputs

Potentiometer inputs are 0-500kohm, linear. Directional inputs are read by a RC delay circuit, i.e. the time it takes a capacitor to recharge after being discharged determines the potentiometer positions.

• North=0 ohm between pins 9 and 11
• South=500 ohms between pins 9 and 11
• West=0 ohm between pins 9 and 10
• East=500 ohms between pins 9 and 10

I don't know how competent you are in technical stuff -and if you aren't you should not be drawing conclusion from wiring schemes- but that means that the input (ie the stick position) was coded linearly as a resistance between pins 9 and 11 for the y axis and between pins 9 and 10 for the x axis.

Linearly meaning that if you displaced the lever twice as much, you got twice as much electric resistance. Displace the lever in any direction and you would have a number between 0-500 on the y axis and another 0-500 number on the x axis.

That's what an analog control is, as opposed to a digital one: you don't just have a binary 0/1 bit telling you if you're pushing up, but a whole range of values. Thus the stick was not a digital directional stick.

Was it a crappy controller? Probably, as it was not even self centering as the vectrex one was, but that's not the point.

Go read the wikipedia article to find other examples of analog console controllers predating the n64 one, there is even a sony double analog flight stick mentioned. And let the whole argument go.
