Don't let being offtopic interrupt.
This mod seems good and the best part is it doesn't even need a wii console.
If you can lay your hands on a wiimote that will suffice.

Supply will increase massively soon (1)

In this Mercury News interview with Reggie Fils-Aime [mercurynews.com] he pretty much gaurantees that they still wont meet demand for the holidays. Here's the nugget:

We're working very hard to make sure that consumers are satisfied this holiday, but I can't guarantee that we're going to meet demand. As a matter of fact, I can tell you on the record we won't.

I guess I'm going to have to start trolling target, walmart and such on a regular basis.

Re:Supply will increase massively soon (1)

rbarreira (836272) | more than 6 years ago | (#21328235)

I hear that the best way to pick up a Wii is to look at stores' weekly leaflets and check if the Wii is shown there. If it is, show up on Sunday morning before the store opens. You can also call in advance to find out whether they'll have stock or not.

Re:Supply will increase massively soon (1)

Elsapotk421 (1097205) | more than 6 years ago | (#21330027)

I live on an overseas military base which makes it just a bit harder to get since we don't get as much stock of stuff as civilians stores (heck we don't even have guitar hero 3 yet) What they would do here is raffle the chance to buy the wii since military members would all be at work and hte wives would just pick them all up and leave us working guys out of look. I walked in randomly one evening about 5 minutes before they closed and saw a whole bunch on display...so for what it's worth maybe you can pick one up that way.

Fortunately, these guys all publicly announce when they'll be receiving shipments via their ads. Check the new weekly ad online at target.com, etc., before open time on Sunday. If the new ad advertises the Wii, it means they're putting a new shipment on the floor that morning. Get in the habit of checking target.com, bestbuy.com, and circuitcity.com every sunday morning.

I managed to score a Wii (in the San Francisco bay area) 9 months ago using this strategy. I just strolled in 90 minutes after opening time; there were a half dozen people in line, and still a stack of nearly a hundred consoles behind the register.

So yeah, you do have to put a little thought into it -- you can't just expect to walk in at 6 PM on a Tuesday and find units in stock -- but it if you know what you're doing, it's really not hard to get your hands on one.

Re:no touch (1)

bigstrat2003 (1058574) | more than 6 years ago | (#21327475)

It depends on where you live. In my area, they're still sold out all the time, I only got mine by having my brother, who conveniently worked in Target's electronics dept, snag me one. I know in some places, you can find them, but that's not everywhere.

Re:no touch (1)

CastrTroy (595695) | more than 6 years ago | (#21328029)

It seems to me that there's a big problem with getting them to the right place. I know of many shops in my area that display the "Wii in stock" sign at all times. I got mine about 6 months back by just walking into a shop that just happened to get them in stock. I think this is the best way to go about it. Whenever you are in, or near a shop that sells the Wii, you should stop in and see if they have any. You will probably get one pretty quickly. I only went to about 1 shop a week, since the Wii started selling, and I got one in March. I wasn't really looking that hard, but if you aren't checking every time you are at a store, you are going to be waiting a very long time before you get one.

People are still waiting on wii's? I bought one about 2 months ago by taking one from the shelf at Meijer and paying for it.

I bought mine on launch night, with a whole bunch of other Zelda fanboys, and we bought up the entire supply then and there, along with heaps of other games and accessories. We all then went home over Christmas and played Wii Tennis with family and friends, who then went out and bought up the entire supply through to about May. I'm not sure any of them ever bought any other game.

Wiis were in stock most places throughout the summer, but now Christmas is coming up, and enough little kids now know what a Wii is and why it's cool. The Nintendogs crowd wants in now. So it's out of stock again.

I have successfully purchased two they are not that hard to get. You just need to know when to look for them. 95% of stores that carry them get them saturday night or sunday morning. So if you want one go right as the store opens on sunday and you have a good chance to score one.

I know this is the case with Walmart, Best Buy, Target & Game Stop.

At the end he makes a very good point. Your arms get tired after a while. As cool as the interface in minority report might be....it isn't very practical. Keyboard and mouse interfaces have lasted for so long because they are VERY VERY good....a mouse is a perfect way of interacting with your monitor...you're using a 2d surface to interface with another 2d surface (not to mention the fact that you can let go of a mouse, and it stays in the same place....unlike a wacom tablet, or this thing). If we ever get to a point where monitors truly are 3d (which seems rather pointless to me, albeit cool)...then something like this MIGHT make sense....that is if you tracked it in all 3 dimensions.

When I was in boot camp, sometimes they would punish us by making us hold a pencil. We had to hold it with both arms held straight out. We were young kids in pretty decent shape and it didn't take long at all for it to get pretty painful. Just the weight of holding up your arms can get to be too much after a while.

If they had you hold your arms out to the sides instead of out in front, it would have had another name: Crucifixion. Anything done long enough can be painful.

I'd be very glad to see an actual game or product along these lines as it would introduce more exercise into the lives of the users. A really simple product that would work well with this would be in fast food. instead of having the workers touch a button with their gloves or hands, they just select the option they want in the air. And tell me, what is the difference between mashing the little tiny buttons on a fast food register, and using a system like this. (I haven't worked fast food, so if you know tell me) --The FNP

It was the navy - what do you want? Our day at the range they did it to us with .45s. Holding that up straight out was no fun. But lest some innocent reader think I don't deserve the wimp moniker you have bestowed upon me - the .45 was chambered for .22. I shot 16 rounds if I remember and that was the one and only time I ever handled a functioning firearm while in the military. The last thing the Navy needs is sailors running around on a ship with guns. We had marines for that.

CastrTroy (595695) | more than 6 years ago | (#21327327)

I don't think that something like this would take over as the standard form of input, however, it could be useful for doing things like presentations. Imagine if you were in a small meeting, with about 5 people, and each one had a wiimote, and each one was able to draw things on the screen. Somebody watching a presentation could point the wiimote at a diagram to show everyone exactly what part he was asking a question about. Just because it isn't the best solution in all cases, doesn't mean it's can't be a good solution for some cases. And considering that wiimotes are quite cheap, it could work out as a very good solution.

Re:Good Point (1)

Nebulochaotic (880087) | more than 6 years ago | (#21330787)

That is a very good point. In fact, I found a video showing what appears to be some people using a multitouch like interface such as this to control a presentation of 3d modeling. I think this will become the interface standard for interactive presentations in the future.

Re:Good Point (1)

MOBE2001 (263700) | more than 6 years ago | (#21327653)

Your arms get tired after a while.

I don't see this as a problem. Artists and painters (think Sixtine Chapel, Michelangelo, Da Vinci, etc...) have been using their arms for ages. The trick is that you don't have to keep your arms up all the time. Every so often you must step back to take a look at your work and you drop your arms when you do. All it takes is short rest periods between work.

Personally, I believe that the multi-touch interface is perfect for parallel computer programming [blogspot.com] . In the future, programming will become almost entirely compositional. Just drag'm and drop'm.

that's what was being said in the 80s... the truth is, while it is 'cool' it is a lot more limiting for low level stuff and complex algorithms. maybe some things would work (probably the same sort of programs that will benefit from technologies like adobe's 'thermo' and multimedia work), but just like visual basic was supposed to change the way everyone programmed but fell way short of the mark when people realised that ease of use and *complete* control are essentially mutually exclusive, this phrase (in my opinion) will be one of those phrases we look back on every so often and laugh.

You could probably make this a flat surface representation where the wii not be on your television but below your hand which rests on glass. There are some interface issues that have to be taken into account as controlling something like windows does not work in this situation, but if you had an apple iphone like interface it would work great.

The fuck they are! Keyboards and mice are relatively dreadful, quite frankly. Have you ever tried to draw with a mouse? It's like painting with a shoe. They're also extremely difficult to use for millions of people with various motor-related disabilities. And what's worse using them improperly (which most people do) *causes* disabilities -- carpal tunnel syndrome being the most well known.

They've lasted this long because they're good enough, not because they're great. They're simple, cheap, relatively sturdy, and widely supported.

Keyboards are so difficult to use effectively, almost every school in the country teaches a class (which lasts months) on "keyboarding". It's far from an intuitive interface.

But software will only take you so far. There's a lot of unique PC to human interactions that are possible, but this world needs more hardware hackers.

In any case, this is a neat demo. People have been doing this on a much bigger, 3D, expensive $$$ scale with something called a Vicon Motion Capture System [vicon.com] . They basically take a whole bunch of those cameras, and a whole bunch of LED arrays, and strobe them so that they get a picture of little reflective points from many different angles. They then use some trigonometry to figure out where, in 3D space, a particular point is. Cool stuff -- good to see it's being brought closer to everyone's homes, rather than the tens of thousands of dollars that Vicon charges.

"Holy Grail" is pretty old tech already (5, Interesting)

bobbaddeley (981674) | more than 6 years ago | (#21327501)

The "Holy Grail" of multitouch without the touch is a pretty old problem. I've been working on something at Pacific Northwest National Laboratory for a while called the HI-Space table, and it was around before I came to the lab. It uses infrared and a camera and detects multiple inputs simultaneously, as well as object placed on the table. It doesn't require touching at all and works fairly well, detecting not only single fingers but each of the fingers, allowing the user to do different things with different arrangements of fingers. It understands motions as well, and can detect a swipe, circle, etc. Objects aren't tagged with anything special; they're just cardboard shapes.

Here's a video of the HI-Space table in action: http://www.youtube.com/watch?v=nFBoq1i81V4 [youtube.com]

Re:Stuck in our past. (1)

Gage With Union (1174735) | more than 6 years ago | (#21332347)

We keep thinking things like this are a good idea. For instance, the Theremin [wikipedia.org] , after a burst of initial popularity, never took off. Though it looks easy to play, it's in fact quite difficult, because there's no tactile feedback. Coming in at the right pitch after a long rest is hard, which is why you don't see many pieces for orchestra and Theremin; instead, the Ondes Martenot [wikipedia.org] , which has a keyboard to indicate pitch, is used.

There's a rift in the Theremin world over people who play in the traditional touchless manner and people who slide their finger along the surface of the instrument. The latter is substantially easier as it reduces the mental calculation of distance to one dimension, and means that you can mark the exact location of pitches, which is a pretty good sign that touchless isn't all it's cracked up to be.

Danger to eyes (4, Informative)

Anonymous Coward | more than 6 years ago | (#21327577)

I would be careful making very bright infrared light. Because your eyes do not pick them up, your pupils will not know to shrink in bright infrared light.

I would suggest doing this in a very well lit room, and NEVER in the dark, or you will likely seriously damage your eyes.

Re:Danger to eyes (4, Insightful)

francium de neobie (590783) | more than 6 years ago | (#21327837)

Exactly the same thing I've been thinking after watching the demo. Although our eyes cannot see the IR light it can still pass onto the retina without much trouble. Using that thing for an extended period of time would quite probably damage the eyes.

Anything that's warm gives off IR light. Are you saying in a dark room looking at another person for too long will do damage to your eyes?

This thing gives off IR in a different frequency than the human body of course, but if in general IR light is "dangerous", then we'd all be blind years ago.

Using that thing for an extended period of time would quite probably damage the eyes.

I doubt it. IR is lower in energy/photon than visible light. As long as it's not heating up anything (which you'd feel on your skin at the least), I'd doubt it'd do any damage at all.

Re:Danger to eyes (0)

Anonymous Coward | more than 6 years ago | (#21328509)

(OP of the danger post here)

Yes, there is IR everywhere. But the IR that a warm body gives off is not very bright. I don't know how bright those LEDs are, but I have seen (from working in the LED field) infrared LEDs that are powerful enough to blind you with less than a minute of direct exposure, lest you have proper eye wear.

So again, I don't know the strength of the LEDs used. It could be that the IR radiation is way too low to cause damage. I am just saying to be aware that the danger may exist.

The near-IR light given off by this type of device has very little to do with thermal IR. It is much closer to visible red light, just a bit lower frequency (a couple of hundred nm or less difference, versus thermal IR being closer to ten times lower frequency).
Human eyes are also opaque to thermal IR, which is related to what the GP was getting at - near-IR is potentially dangerous because your eyes are transparent to it, but your retina has very little sensitivity to it. I doubt the amount of NIR illumination here is very significant, but imagine the equivalent of having a bright flashlight stuck in your face, except without the ability of your pupils to contract in response.

I think you might be getting confused about the risk of IR lasers and IR light in general. Although it is true that IR light is more dangerous than visible light in a laser context for exactly the reasons you have listed, the non directed IR light used in this senario will not harm your eyes.

Am I the only one somewhat uneased by the though of having an array of 30-40 relatively high-power leds shining in your eyes without ones pupil contracting? Or might it be that the wavelength of the IR leds happens to be absorbed by water in the eye? Anyone with some knowledge?

No worries, unless your eyes are capable of picking up IR. On second thought, this might make an excellent anti-Predator device.

I do know that sufficiently high intensity IR can be very damaging, coagulating the cornea or "burning" the retina, it's especially dangerous as you can't see the light, you just get your eyes fried. So IR is definitely not inherently safe, on the contrary it's potentially very dangerous, though I'm not at all sure how much light is needed.

When hot objects emit IR they emit it in a very wide range of frequencies, and thus the intensity at any individual frequency is not to high, but the total amount of energy deposited can be large enough to be dangerous. With an LED it is the exact opposite. The LED emits relatively little IR, but it pumps it all into a quite narrow range of frequencies. The consequence is that your detector can distinguish the LED light from background noise, even at relatively modest power levels. Is this enough to make the above experiment safe? Well, I'm not a doctor nor an optician, so I dunno what could be considered safe, but I would suspect that it can be easily done at intensities lower than what would be dangerous.

The goggles they do nothing (5, Funny)

I'm sorry for the awful picture you will get in your mind if you continue reading.

But it occured to me that you could use a penis instead of a finger (giving it another use beside: http://www.penny-arcade.com/comic/2007/03/21 [penny-arcade.com] )

(Why, oh why this thought came to me...)

I already do, thouhg it's muhc harderr to ytype with.

I'm no doctor, but it can't be good to flood your eyes with infrared light.

This would be easily fixed by just putting the LEDs on your fingers, instead of reflective tape. Yeah, you'd have to wear some kind of glove thing, but you could also pulsate different gloves' LEDs at different frequencies and have multi-multi-touch for situations with more than one player.

1) You can't see infrared light

2) It can damage your eyes, however to do so from a distance it would be certainly hot enough to melt in a second the device emitting it

(Infrared == heat)

Re:safe to use? (3, Interesting)

(Infrared == heat)
This is not quite true. If (infrared == heat) then (visible light == even hotter heat). Every thing emits light. Things at normal environmental temperature (0-100 degC) emit primarily in the long-wave to mid-wave IR (about 10000nm or so). A typical IR LED emits in the near-ir (about 900nm or so) which corresponds to about 1000 degC or so. Red light, which is about 700nm, corresponds to about 3000 degC or so. So saying infrared == heat is very misleading. Caveat: the number are off the top of my head so they may be slightly off.

A bright enough near-ir LED can damage your eyes, just as a bright enough visible LED can damage your eyes. The difference is that you notice the visible LED long before it starts to damage your eyes, but you won't notice the IR LED until perhaps it's too late. People who work with lasers (such as myself) have similar issues, you have to be very careful around IR lasers because you won't know if they are damaging your eyes until it's too late.

Given that, I doubt these LEDs are bright enough to do any damage.

Isn't this what the MPAA is using now? (1)

MooseTick (895855) | more than 6 years ago | (#21337119)

Perhaps I'm mistaken, but I vaguely recall seeing a article about the MPAA shooting infrared light from behind movie screens into the crowd to determine if anyone was using a camcorder to copy live movies.

The unanswered questions (1)

Evets (629327) | more than 6 years ago | (#21328141)

While this was an impressive video, it leaves me wondering how to try it out at home. I assume there are more than a few web pages talking about grabbing wiimote data via bluetooth, but what software could you use to display multi-touch inputs on a PC screen?

Re:The unanswered questions (1)

grumbel (592662) | more than 6 years ago | (#21329065)

Any Wiimote software that can display the raw IR data will work (wmgui for example). However, thats the easy part, the hard part is finding software or writing it so that you can actually do something usefull with that data.

Doing the same with a WebCam vs. Wii Remote (1)

bradgoodman (964302) | more than 6 years ago | (#21328335)

I am pretty sure you could do the same thing with a Webcam instead of a Wii Remote.

This is actually a little closer to how a multi touch "surface" does it.

This would merely require - as many DIY multitouch sites mention - removing the IR filter from your Webcam - and perhaps even replacing it with a visible light filter, as to pass IR only.

hmmmm idea! (1)

kaizokuace (1082079) | more than 6 years ago | (#21328771)

Since wiimotes are cheap and they seem to be sensitive enough and the bluetooth is usefull, can these IR camera setups be used in say a group of minimum of 3 but the more the merrier of course to build a mocap rig? Of course some good softwares will be needed but I am sure the community will provide me with that.

Easier just to use two remotes? (1)

gilesjuk (604902) | more than 6 years ago | (#21328811)

No need to even solder a single wire if you point two Wiimotes at the screen and use their relative positions to do stuff.

Google Earth + Atlas Gloves (1)

Mctittles (973829) | more than 6 years ago | (#21328911)

Just in case anyone wanted to try something like these. You can make a similar interface with a webcam and lighted fingers and surf google earth with it. Intructions are here: http://atlasgloves.org/ [atlasgloves.org]

Just one thing... (1)

Roager (1188827) | more than 6 years ago | (#21347275)

As cool as this is, I don't see it being useful anywhere for one simple reason: if the wiimote is up on the tv, you don't get buttons. Wonderful for pointing at stuff, or even just for kicks and giggles, but you couldnt even make a mii with this hack.
