here you go: http://snippets.dzone.com/posts/show/4920
the library, a demo (win32-only) and a misc. file
take a look at it, I published it under GPL
let me know where you get stuck:)
ok, here's one more question: how do I make sure that you don't go running off with my code?:)
The library is pretty small and then there are some small examples.
How can you be so sure that you can figure out how it works? I'm a pretty messy coder
Don't mind me being a bit paranoid about this, I'm nex at this:)
where should I put the sourcecode? I don't have any documentation to be honest, but I do have some demos. If you have the time and patience you could easily figure out how it works. You should keep in mind though that the resolution of the motion detection is limited to the resolution of the webcam.
A more interesting hack would be to simulate what the Wii does (ie having an IR emitter and have a webcam track those) but that would be infringing patents I believe. I'm pretty busy lately (working on my dissertation and what not) but if you're serious about this I'll try and allocate some time for you.
I made something similar in using python and a webcam. My hack was pretty simple: 1) IR webcam 2) IR-pen, similar to this guy's 3) software in python to track the IR light 4) demo-apps in pygame (tracking, swinging, 2 player pong)
It worked pretty well to be honest. I also atached some LED's to a wireless mouse and controlled the mouse from distance (similar to but not as good as the wii-mote).I tried to add multiple inputs using one cam by using color video input and color LED's instead of IR LED's, but then school started and I had to stop my project (lack of time).
It's a fun but useless project: the wiimote is so cheap that there is no need for a homebrewn version like this. It also suffered from the same things the Wii did, mainly IR pollution. I stil have the source code lying around but I don't know what to do with it.
I bet thousands of years ago somebody said: "yes, burning wood may be a good means of creating heat, but we might end up burning all the wood and then we're doomed..."
it works in batteries, and I bet it's waterproof to some extent (as you can wash it by hand)... I bet we'll bee seeing a lot of applications for this kind of "cloth".
What part did you not get?
>>The games changes cause the top of the compaies does not gamers anymore ,
Games are changing because game-studios are run by non-gamers
>>so what they understant from improvements is the changes and this effects the playability of the Games.
These people (mostly the suits, manager types) think that changing a (good)game is improving it. This has an effect on the playability of the games.
I hope so time shows me that I am wrong.

if you need to get more linux gamers to attract more linux-support from game developers... you get a chicken-egg problem:
gamers won't come to linux if it's not supported by dev companies dev companies won't support linux if gamers don't migrate
a better solution would be: more quality open source/linux games that can equal the polished commercial counterparts. free-games usually lack decent artwork or decent menus or whatnot... they even lack decent stories.
so the plan is: - get bunch of talented people together: writers, graphics, musicians, sound people, programmers, people to write documentation, offer support,...
all in all I don't see this happening in a soon future... yay wintendo:)
It's dead, believe me
Don't get me wrong, I'd choose IRC any day over MSN, but the whole thing is, when every-every-body who you know IRL uses MSN you're much more inclined to use it over IRC.
You see the whole problem started a couple of years ago in Belgium: as internet connections became more widespread non-geeks tried to chat too.
I remember it was a whole hassle to get a person connected to IRC (I spent hours on phonelines telling people how they could connect ("now type/server irc.undernet.org.. no not there.. no the other window..").. they would give up and use MSN instead.
I still visit irc.debian.org (don't remember which network it was) to visit #python or any other channel for some advice. it's not the same though.. IRC was more social than any of there IM things can ever be.
you're right but I remember a time my MSN list was my IRC channel list. good days they were:/ the whole "chat scene" seems to be left to pervs and haxors lately:p although I sometimes jump into a channel to for some help with python for example
I try to avoid it

just like I'm not fond of writing letters IRL I don't like writing E-mail and I only do it when there is no other choice (usually for official stuff or things I want to have a record of). I rather have IM. (or IRC, but that's officially dead...)
I did consider the spring system, but I believe the metal hairstub method would be a better option, but you could combine it with a springsystem ofcourse.
This device would not give you information about your location. Only your rotational orientation along the XYZ-axes in regard to the earth (where most nintendo games are played)
So this is not the "controller" itself, merely the part that would do the rotating and shaking.
yeah, the toy plane was over 15 years ago, but the caged-ball method is older than that. It's implemented in animals.
If I'm not mistaken many animals use the caged-ball method: take the human ear. It houses a small room which is filled with a liquid and nerves. The position of the fluid allows the brain to calculate the orientation. It's not a ball, but it's the same technique.
Even crazier, somebody who studies biology told me that lobsters have a small dent on their body and they put a grain of sand in it, succesfully applying the caged-ball method. When the grain falls out the animal loses orientation until it can put in a grain of sand again.
I should point this out, regarding your statement about not needing gravity According to the Equivalence principle in general relativity, the effects of gravity and acceleration are the same, so an accelerometer can make no distinction between these effects. http://en.wikipedia.org/wiki/Accelerometer
note: the caged-ball method probably has a real name.
What if we'd replace the ball, but keep the sphere.
We'd pad the inside of the sphere with short metal hairstubbs (with a small weight at the ends?). When a stub is positioned right, it's weight forces it down into a hole and closes a circuit, when it's hanging upside down, gravity pulls the "hair" or "stub" out of it's socket and breaks the circuit.
So you'd be able to scan the matrix in the sphere and get a "fingerprint" of the force working in on the sphere. calculate the center and you'd be set.

I released the code under GPL.
it's actually 3 files:
1) a library
2) a demo
3) a misc-lib to calculate the fps
the code is ver messy so let me know when you get stuck and let me know what you do with it

Actually, in Windows XP you can turn off the unsigned-driver warning messages through the Adminitrative Tools in the local secuirty policies.

man, thousands of books... weird :D
I myself have maybe a couple of hundred (gave away all my childhood books) and I don't find time to read them!!
10.000's of books? what's your line of work?
well he IS right. Isn't it the name of Apple's latest OS's GFX engine?
Well okay, you don't need physical access to the card anymore to steal money from it.
They're gonna need to put in some confirmation thing in this, but I thought the whole idea was effortless payments.
or atleast MS Office could become free, under pressure of OO.org. maybe they could sell support or something.
I'd love that, free MS Office (free as in beer)
