Head Tracking w/ the Wiimote

Hardware Hacking 169

mrneutron2003 writes "This guy just doesn't know when to stop. Johnny Chung Lee graces us with yet another one of his inventive Wiimote projects. This time it involves using the Wiimote and a pair of inexpensive LED safety goggles (with the standard LED's replaced with InfraRed ones) to allow positional head tracking , achieving an effect similar to what is experienced with three dimensional displays and CAVE systems. The video dramatically illustrates the effect. Game developers take note. This simple little variation on infrared tracking could allow for some seriously immersive gameplay in the future." This guy deserves a medal.

let me know when nintendo's wiimote can do this (-1, Offtopic)

Anonymous Coward | more than 6 years ago | (#21797886)

With both hands deep inside the blond surfer's body, while he ingests my
giant cock, I open my arms to stretch his back entrance even more and
prepare him for what'll come next. Then I pull both arms out. The boy's anus
is as wide as a mainpipe. I can see the pink velvety walls inside, throbbing
with hunger for more invasion.

I apply a strong bent knee to the crater, forcing the ring until the patella
pops in. Circling my knee, I get the now grotesquely extended sphincter to
stretch even further. Slowly I slide more and more of my bent leg through
the breach, extracting heartbreaking screams from the tortured boy.

It's time for what I really have in mind. I take my knee out, with a loud
PLOP!, open Tom's legs, taking a good grip on his strong thighs, brace
myself and plunge, shoving the top of my head inside his asshole!

My shaven, smooth pate almost fits into the gargantuan gap of what used to
be, not too long ago, the young man's tight anus. I wriggle my head, shake
it to and fro, slowly shoving the top inside, using the surfer's flesh ring
as a new kind of crown.

Surprised at the size of this new invader, Tom brays like a butchered
animal, struggling to free himself from my grip. That only makes my job
easier, as I jam more and more of my head into his open grotto.

I'm up to my ears into Tom's gorgeous butt, enjoying his warmth and tight
embrace of my skull, and even though it may kill him, I have to go further.
I pick a respirator in the CPR box and stick the two tubes into my nostrils.
I'm now ready to dive into the helpless surfer.

I close my eyes and plunge in. Breathing through the respirator, I have now
my whole head inside the boy, feeling his fast heartbeat loud in my ears,
the sweet mucous of his bowels mixed with all the cum I have poured inside
him, and the appeal of the tunnel ahead, calling me to unplugged depths.

I start to move my head back and forth, fucking Tom with a really gigantic
black phallus, while he goes back to sucking my cock. He seems to be more
relaxed now, geting used to the new invasion, and aroused by the extra
pressure in his guts.

I open my mouth and bite into the tender flesh, until I find my prize: the
hard truffle of the boy's prostate, that I roll between my teeth and tickle
with my tongue. I feel Tom's whole body shaking around my head. He's cumming
again!

His convulsing bowels squeeze my head, trying to swallow more of me. It's a
pity but my heavy shoulders are too wide to fit into the boy, otherwise I'd
keep on plunging inside him.

Satisfied with this new experience, I pull my head out with a loud PLOP! The
boy has survived. Even better, he has enjoyed a massive orgasm, with my head
fucking his butt. He's ready for more cock. But he's now too loose for
Grossao to take care of him alone.

So I call Junior, the other lifeguard on duty, to help me. He runs up the
stairs, happy to oblige. He has been listening from downstairs to the sounds
of Tom's rape, and I know he's hard and ready, as always, to help me out.
He's a big black stud like me, with a huge dick, almost as big as Grossao.
Tom's torment is far from over.

This reminds me of a story (-1, Troll)

Anonymous Coward | more than 6 years ago | (#21797900)

A few years ago, while browsing around the library downtown, I
had to take a piss. As I entered the john a big beautiful all-American
football hero type, about twenty-five, came out of one of the booths.
I stood at the urinal looking at him out of the corner of my eye as he
washed his hands. He didn't once look at me. He was "straight" and
married - and in any case I was sure I wouldn't have a chance with
him.

As soon as he left I darted into the booth he'd vacated,
hoping there might be a lingering smell of shit and even a seat still
warm from his sturdy young ass. I found not only the smell but the
shit itself. He'd forgotten to flush. And what a treasure he had left
behind. Three or four beautiful specimens floated in the bowl. It
apparently had been a fairly dry, constipated shit, for all were fat,
stiff, and ruggedly textured. The real prize was a great feast of turd
- a nine inch gastrointestinal triumph as thick as a man's wrist.

I knelt before the bowl, inhaling the rich brown fragrance and
wondered if I should obey the impulse building up inside me. I'd
always been a heavy rimmer and had lapped up more than one little
clump of shit, but that had been just an inevitable part of eating ass
and not an end in itself. Of course I'd had jerk-off fantasies of
devouring great loads of it (what rimmer hasn't), but I had never done
it. Now, here I was, confronted with the most beautiful five-pound
turd I'd ever feasted my eyes on, a sausage fit to star in any fantasy
and one I knew to have been hatched from the asshole of the world's
handsomest young stud.

Why not? I plucked it from the bowl, holding it with both
hands to keep it from breaking. I lifted it to my nose. It smelled
like rich, ripe limburger (horrid, but thrilling), yet had the
consistency of cheddar. What is cheese anyway but milk turning to shit
without the benefit of a digestive tract?

I gave it a lick and found that it tasted better then it
smelled. I've found since then that shit nearly almost does.

I hesitated no longer. I shoved the fucking thing as far into
my mouth as I could get it and sucked on it like a big brown cock,
beating my meat like a madman. I wanted to completely engulf it and
bit off a large chunk, flooding my mouth with the intense, bittersweet
flavor. To my delight I found that while the water in the bowl had
chilled the outside of the turd, it was still warm inside. As I chewed
I discovered that it was filled with hard little bits of something I
soon identified as peanuts. He hadn't chewed them carefully and they'd
passed through his body virtually unchanged. I ate it greedily,
sending lump after peanutty lump sliding scratchily down my throat. My
only regret was the donor of this feast wasn't there to wash it down
with his piss.

I soon reached a terrific climax. I caught my cum in the
cupped palm of my hand and drank it down. Believe me, there is no more
delightful combination of flavors than the hot sweetness of cum with
the rich bitterness of shit.

Afterwards I was sorry that I hadn't made it last longer. But
then I realized that I still had a lot of fun in store for me. There
was still a clutch of virile turds left in the bowl. I tenderly fished
them out, rolled them into my handkerchief, and stashed them in my
briefcase. In the week to come I found all kinds of ways to eat the
shit without bolting it right down. Once eaten it's gone forever
unless you want to filch it third hand out of your own asshole. Not an
unreasonable recourse in moments of desperation or simple boredom.

I stored the turds in the refrigerator when I was not using
them but within a week they were all gone. The last one I held in my
mouth without chewing, letting it slowly dissolve. I had liquid shit
trickling down my throat for nearly four hours. I must have had six
orgasms in the process.

I often think of that lovely young guy dropping solid gold out
of his sweet, pink asshole every day, never knowing what joy it could,
and at least once did, bring to a grateful shiteater.

Just because Nintendo hasn't created a product for the mass market doesn't mean that nobody at Nintendo has thought of it yet. Here's some other ideas for the Wii. A hard drive, or a keyboard for the browser. Those are the first things I thought of when I first got my Wii. From what I understand, you can use a USB keyboard on the Wii menu now, and they are in talks with a USB driver maker to get USB hard drives working. However at release, they didn't have any of this. Did we all think we where geniuses for thinking of this stuff? Granted I think the stuff he's doing pretty cool, but just don't assume that just because Nintendo doesn't have a product, that they haven't already thought of this.

Not to harsh your buzz, but there is a reason head tracking systems are not widely popular for gaming.

The PC Gaming landscape is littered with failed head-tracking systems. The reviews inevitably say something like "this thing is awesome, but fatiguing."

There are eye-tracking systems that are not nearly as fatiguing, but if you've seen one, you'll understand why they haven't taken off in popularity.

The Wii appeals to people who wouldn't touch PC games, and given the physique of the typical PC gamer, I can see why it would be "fatiguing" -- I imagine most PC gamers, even if they have a Wii, aren't standing up to play it because that would be fatiguing too.

Dr_Barnowl (709838) | more than 6 years ago | (#21799748)

I think this is less of an issue with the Wii because the input device moves with you. With the PC you are craning your neck while you keep your hands on the keyboard. With the Wii, it's almost difficult NOT to move the input device in sympathy with what you're doing onscreen.

He won't get a PhD for this - none of the work is original, we built exactly the same thing with a video camera and an Ikonas frame buffer in... 1984.

However, I'm sure the fellow knows this (he uses the right name: FishTank VR - google it) and it looks like this is his hobby.

What he has done is exposed a much larger audience to the possibilities by using relatively cheap and (eventually) easy to get hardware. Kudos to him!

The problem with game peripherals is that the sell through rate is so low that not enough people buy them to make it worthwhile to create games that fully exploit the hardware.
So even if the game is just a pair of cheap glasses with leds on them it might not sell just because of that little extra expense.

Someone should figure out a way to make a game that uses this without buying any extra hardware - you might have a winner.

Well if Nintendo doesn't hire him and he doesn't start his own gaming company these ideas will never land on the Wii itself, and while it would be cool to play games using this on the PC the market for people with the know-how to connect their wiimote to their PC (and get around all the stupid driver limitations and stuff) is exceedingly small compared to the market for people with Wiis.

Since this involves glasses with LEDs mounted on the sides, I'd love to see this combined with the various [wikipedia.org] glasses [wikipedia.org] out there for stereoscopy [wikipedia.org] .

Polarized filters and LCD shutters aren't anything new, and I'm sure they've been combined with head tracking before... But I don't think it's ever been quite as accessible as it is now. Stereoscopy + head tracking + a pointing device like the Wii remote could make for one hell of game.

Re:DUDE (1)

CastrTroy (595695) | more than 6 years ago | (#21799374)

Why not just use 2 wiimotes, so they can see in 3D, just like people do.

Polarized light not compatible with LCD (4, Informative)

Dr_Barnowl (709838) | more than 6 years ago | (#21799712)

Alas, shutter glasses(a polarized screen with an LCD shutter) and cross-polarized glasses don't play with LCD displays, because LCD uses polarization to turn the pixels on and off. LCD latencies are also a little high for shutter glasses.

They only work with DLP projectors (uses little mirrors), CRTs, plasma, and upcoming display technologies like Field Effect Displays and LED displays. Obviously there are a lot of display technologies that do work there, but LCD is a very popular technology for widescreen TV and of course, for PC monitors.

Either way you do it, you also have to double the grunt of your rendering system (or half your graphical complexity), and you need specific software support to get it right (you can go a long way with a driver that knows it's rendering for stereoscopy and just produces the correct eye POVs, but the glitches you get in the foreground and HUD are only tolerated by enthusiasts.). With shuttering you need glasses. With cross polarization you need to double the number of display elements (by having two displays or a special display with double the horizontal resolutions). Used in POV applications, all of these technologies are a one-user gig.

Stereo "Wii-D" will probably never happen ; half the audience have an incompatible display device, the system does not have an enormous excess of GPU grunt. Stereo3D would only be common with one of the following display devices...

  * Personal head-mounted 3D display (probably VRD goggles)
  * Large area wide aspect flatpanel displays with inherent stereo 3D support built in at the factory (which means basically doubling the vertical rez and making a special polarized filter for the screen). ... an no-one is going to build the latter until there are plenty of mainstream 3D apps to support the market.

The parallax effect that Johnny Lee demonstrates conveniently exploits the tendency of the human brain to "fill in the gaps" ; I'd be intrigued to see how convincing it really is.

As another poster points out, head tracking really isn't very well received for the PC, because the PC is an inherently static device. You can move your head, but your hands have to remain fixated on the keyboard / mouse. The Wii has an advantage here because the input device moves around with you. Several times during Zelda I got up from my chair and started moving almost involuntarily, my whole body was immersed in the game. I would never have tried that on the PC ; when I feel the urge there it probably just contributes to my neck tension.

If the static, 3rd person POV of Zelda can make this gamer rise up and move, a game armed with a head tracking linked POV would be compulsively immersive, even without stereoscopic 3D.

LanceUppercut (766964) | more than 6 years ago | (#21798106)

The system in the helicopter is in no way "similar" except from the fact that it used head tracking. Head-tracking helmets have been used for aiming weapons in aircraft for quite sime time now. Mass-application of the concept originates from Soviet fighter planes, MiG-29 being the most notable example.

Wiimote with ability to track more points? (1)

Denial93 (773403) | more than 6 years ago | (#21798078)

The Wiimote can only track four IR sources at the same time, which seems a fairly arbitrary limitation that should be trivial to lift. With the IR light sources uniquely identified through signals encoded in the light stream, many more could be tracked. Shouldn't Nintendo upgrade the Wiimote quicky to allow for tons of new applications?

Re:Wiimote with ability to track more points? (2, Insightful)

bipolarpinguino (944613) | more than 6 years ago | (#21798914)

from my understanding, the limit is imposed by the bandwidth-per-point transmitted over bluetooth, and not the onboard image processing on the wiimote.

Re:Wiimote with ability to track more points? (2, Insightful)

LiquidCoooled (634315) | more than 6 years ago | (#21799874)

Nahhhhh bandwidth isn't that limited.
Remember the core wiimote can handle an additional nunchuck or the classic controller, each of which requires more data than the small amount of data per frame required.

If Nintendo wanted to do this anyway I believe they would use a custom device with its own interface (and would almost certainly retain the power connection the current sensor bar uses).
There has been rumour that the next wii will be controller less, people simply acting out the actions to get results.
This will be done via sophisticated processing of a normal image and not be limited to having to stick baubles onto our bodies.

Having said that I am fascinated by this technology and find his 'hacks' amazing.

Just take a look at http://free-track.net./ [free-track.net.]

This little software feeds the TrackIR interface from a cheap webcam. Since it doesn't use a Wii it won't make you more attractive to the gender that you prefer being attractive to, but then you get full six degrees of freedom, which a Wii sensor bar can't do (it has only two points to track). Only trouble is the weak framerate most webcams have, and horrible webcam drivers that can suck away a considerable amount of CPU time.

You could probably do it with a high-res webcam, a couple of really bright LEDs with an easily trackable color, and some math. Heck, they could be IR LEDs if you pull the IR filter out of the webcam.

Please, give us some games that use this, give us multitouch tablet Macs (sorry windos fanboys, microsoft could pull it off technologically, but it wouldn't be useable), give me a VR multitouch table! Now! The flying car can wait until next year...

processing power (1)

ampsonic (788883) | more than 6 years ago | (#21798214)

Does the Wii have enough horsepower to pull this off on its own? The demo was running on his PC, and I'm curious how processor intensive something like this would be.

Re:processing power (1)

ScrewMaster (602015) | more than 6 years ago | (#21798252)

It looks like most of the processing is being done by the remote itself, so I'd guess that all the PC is doing is processing co-ordinates for a couple of moving points.

Re:processing power (1)

ampsonic (788883) | more than 6 years ago | (#21798298)

Well, doesn't whatever system you are using have to re render the entire "room" everytime the head changes position? Although, I guess this is really no different than having real time control of the "camera" in a game, which has been done since N64, so perhaps it will work just fine.

Re:processing power (4, Interesting)

cowscows (103644) | more than 6 years ago | (#21798390)

Correct. As far as the rendering engine is concerned, whether you're moving the camera with your head or a mouse, it's all pretty much the same. This guy is probably using a PC instead of the Wii because it's much easier to get code running on a PC than a Wii (you don't need Nintendo's SDK), which makes it cheaper and more useful to share the code with others.

Re:processing power (4, Interesting)

datajack (17285) | more than 6 years ago | (#21798314)

Not very.

Not to trivialise what Johnny is doing there is basically measuring the position of the wiimote in relation to the sensor bar - something it already does. The code to do this shouldn't be that difficult. The true genius was in him realising that you could do this easiest by reversing the moving component and the stationary component.

Apart from some smoothing algorithms, this is no more complex than reading the wiimote's pointer position and mapping that to a camera viewpoint.

Re:processing power (4, Insightful)

Tom (822) | more than 6 years ago | (#21798634)

Which is the whole beauty of it! The second thing I thought when watching the video was whether I could possible create a small game around that concept (I'm a hobbyist game developer).

It's so simple that you can do something with it, without having to wait for IBM, or Nintendo or any other big-$$$ company to bring out the relevant hardware in maybe 5 years.

Re:processing power (1)

CODiNE (27417) | more than 6 years ago | (#21799700)

That's what I was thinking, just strap the wiimote to the head and flip the numbers around a little to do the same thing. No need for special hardware that will end up like the power glove, used in 2 games and then collecting dust.

Plus we can yell out "Yo mamma wears a wiimote with a chinstrap!!"

Re:processing power (1)

Starpping a wiimote to the head is a) haver than two leds and b) opens up the user to a whole menagerie of xxx-head jokes.

### Why the Wii isn't for "serious" gamers?

Just because somebody does cool stuff with a Wiimote on a *PC* doesn't mean you will *ever* see something like this on the Wii. Remember this is homebrew stuff, not 'cool new games' that Nintendo will be releasing next year. The issue isn't that you couldn't have fun with the Wii, but that Nintendo really doesn't release much interesting stuff.

Re:Remind me again... (1)

Jaktar (975138) | more than 6 years ago | (#21799128)

A firmware update and 2 new peripherals(the goggles and stationary wiimote) are all you'd really need. This is a simple reversal of the current control scheme already implemented. There are enough 3rd party developers to make a decent game using this. Square-enix, Konami, Hudson Entertainment, EA, Orb, Ubisoft, Activision, and Sega are all current developers on the Wii. Couple that with the fact the development costs on the Wii are about 25% of the 360/PS3. Your comment that Nintendo doesn't release much interesting stuff doesn't hold true. Take a look at any gaming site and check their top rated games for this year, Wii games have made that list. Let's not forget that the Wii was glossed over initially by developers and they're still scrambling to catch up. PC games have been tied to the keyboard/mouse/joystick and will be staying that way for the forseeable future. Nintendo, on the other hand, has never been shy about throwing more peripherals out there and putting them to use. Their success hasn't always been great (power glove, virtual boy, Robbie), but the Wii was built around this "motion sensing gimmick" (as it was called when it was released). The only real problem I see with putting this type of system on the market is that Nintendo would be faced with even more shortages than they already have.

No, what you need is Nintendo willing to do something beside dumbed down casual gaming. All the theoretical cool things that you could do with the Wii means nothing as long as Nintendo can't even get trivial core issues fixed (crippeled online multiplayer, lack of support for play-from-SD, lack for USB storage, lack of proper Wiimote calibration for lightgun shooters, etc.). At this point in time I have exactly zero hope to see something like this from Nintendo.

Because many people refuse to buy the gamecube AGAIN just to get the damn gimmicky controller. Plus, there's a real dearth of decent games for the system.

If the head tracking is as good as Johnny makes it out to be, it'll easily be duplicated by 3rd parties and you won't need to pay the nintendo tax to use it.

when you turn your head to look at something in an appache, the machine gun follows. When you turn your head and the Wii follows....You're not looking at the screen anymore. I tried the wii at a best buy and I almost threw it through a wall. I don't know if it was broken or what, but it sure was a pita to get it to do anything.

Re:turning your head. (1)

Ok I couldn't get on youtube before, and I just saw the video. So.... I guess, I recant my previous statement about looking the wrong direction. I've got to say that it looks pretty cool. If they make a first person shooter using this I would buy one that day. Until then, the only thing the wii offers me is mario party which is only fun if you're high, and I can't do that sort of stuff. Oh and Can I get a mount to attach the Wii remote to my AR-15? with a trigger pad? actually it's infrared right? wasn't the gun from duck hunt infrared?

Re:turning your head. (1)

Jackmn (895532) | more than 6 years ago | (#21799964)

You merely need to increase the sensitivity so that turning your head a small amount corresponds to a large amount of movement in-game.

TrackIR does the same thing, and has been used by many people playing flight simulators for a number of years now. It is leaps and bounds ahead of using a view hat and/or taking your hands off your HOTAS setup to fumble with a mouse.

Remember the PowerGlove? (1)

Animats (122034) | more than 6 years ago | (#21798528)

It's been done. Remember the Nintendo PowerGlove [wikipedia.org] ?

Incidentally, if you've never tried gloves-and-goggles VR, it's cool for about ten minutes. Trying to do things by making gestures in the air is a huge pain. Without tactile feedback, it's tiring and inaccurate. I tried most of the VR systems in the first round, including Jaron Lainer's original system. No good.

It might not suck if the system had an end to end lag of under 10ms. "Turn head, wait for view to catch up" systems drive the user nuts. That problem was solved by "cave" type systems, where the user is surrounded by screens. Bulky, but tolerable.

Re:Remember the PowerGlove? (1)

TerovThePyro (970487) | more than 6 years ago | (#21798608)

Interesting thing about the tactile feed back - if you were using a wiimote as a pointer/shooter, it already has feedback with rumble and sound. If you moved over one of the targets it could rumble or make a beep.

Also, the lag didn't seem bad at all.

The firs thought that came to mind was the game which tracked your body/head and moved you on screen (I cannot remember the name now). It added an interesting element to the rail shooter. This could now be duplicated at home without any large amount of extra equipment.

Overall - Nintendo needs to release ANY rail shooters for the Wii, and then implement this functionality for future shooters.

Re:Remember the PowerGlove? (1)

CastrTroy (595695) | more than 6 years ago | (#21799464)

That's what I was thinking. From what I remember, the PowerGlove was a glove with buttons on it, and some crude motion tracking, but nowhere close to the level that can be done with the wiimote.

Re:Remember the PowerGlove? (1)

mblase (200735) | more than 6 years ago | (#21798994)

Trying to do things by making gestures in the air is a huge pain. Without tactile feedback, it's tiring and inaccurate.

Apple confronted this with the iPhone touch screen, IIRC, and solved it by having the phone vibrate ever so briefly when a touch was registered. This gave the sensory impression of a button clicking without actually doing so.

I don't see why a developer couldn't do something like this with VR gloves, then. Using JLC's approach, you'd have "Minority Report"-style gloves that had infrared reflectors in the fingertips but also a small, light motor that would fire for a few milliseconds whenever a "touch" was registered. You'd still have the issue of arm strain, of course, and wouldn't want to use this solution for long-term work, but it would almost certainly improve the usability.

Umm, isn't that what a Wiimote does in it's usual configuration? Just because what you've used before sucks, doesn't mean that the concept cannot be done properly. I think Wii has pretty much proved that.

As I understand it, the infrared detector on the Wii remote is basically a camera with an IR filter in front of it.

Potentially you could just use a webcam with an IR filter in front of it instead of a Wii remote.

Note: 1) there is usually a filter to filter out IR inside most webcams, so that would have to be removed. 2) IR emitter tracking would have to be done on the PC instead of inside the Wii remote.

From his website [cmu.edu] :

As of September 2007, Nintendo has sold over 13 million Wii game consoles. This significatnly exceeds the number of Tablet PCs in use today according to even the most generous estimates of Tablet PC sales. This makes the Wii Remote one of the most common computer input devices in the world. It also happens to be one of the most sophisticated. It contains a 1024x768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz. This significantly out performs any PC "webcam" available today. It also contains a +/-3g 8-bit 3-axis accelerometer also operating at 100Hz and an expandsion port for even more capability.

Generally also, webcams don't have the resolution that the Wiimote has. Aparrently from the specs I've read, the wiimote resolution is 1024x768, something most inexpensive webcams will not do. Your better off buying the wiimote.

Just thought of this. This would be a wicked interface, and much more natural, for someone piloting a drone helicopter or even robotic vehicle.

If you had several monitors, this could be used to make them feel as if they were an actual "pilots seat" of a vehicle giving perfect perspective to the "pilot" because they know where the head is oriented and each monitor could produce the proper peripheral and image views for the "pilot"

It would take a little tricky camera work for the robotic vehicle, but I am sure gratuitous funding could solve those problems.

Why a wiimote? (1)

schweini (607711) | more than 6 years ago | (#21799804)

Why does he always use a wiimote for this? A couple of years ago, i build a basic minority-report-like-wave-your-hand-in-front-of-the-screen UI with a webcam, an IR-LED and a infrared filter in front of the webcam (i simply used the dark-red looking plastic that usually covers the transmitting LED in a regular remote control). I then simply pulled the images from the webcam using some v4l-utility, and ran some (extremly basic) pattern-recognition in perl to detect the white 'dot' that represents the IR-LED that was stuck to my hand, and used it to move the cursor around on the screen - really not too difficult.
If someone would write a nice library for this (using intel's obencv library for the pattern-recognition, for example), almost all the 'hacks' from this guy could be implemented without the wiimote, and this would seriously rock.
apart from that - AFAIK, face-detection (just detecting a face and the position of he eyes in an image) usually works well enough, so this particular hack should even be possible without using any infrared LEDs, and this would be really cool if implemented correctly. Any takers? Becasue it really looks cool in the demo.

Ithil_Mith (930174) | more than 6 years ago | (#21800014)

I've also used webcams as input to capture motion and patterns, the biggest problem with this solution is the refresh rate, which sucks. On the contrary, the wiimote has a much faster refresh rate, which gives you a smoother reponse improving the usability. Citing to Chung Lee ..."It contains a 1024x768 infrared camera with built-in hardware blob tracking of up to 4 points at 100Hz. This significantly out performs any PC "webcam" available today."...
