If you are a programmer Download and install with Wiimotelib programming libraries. Find the sections of the code that grab the coodinates that you are looking for and report them, to... a file, a larger shell program that you write, or what have you. You probably want to let the program normalize them for you, that is let the calibration math happen and get the screen coordinates and not the raw coordinates. You may also need to erase a LOT of other code if you don't want the program to draw anything for you. Read through all of the interesting posts in the "programmer's den" here in this board.

Good luck.

Swimming is the most fun when you go in over your head for a while. What is a "tractor vest" exactly, and are you planning to send signals to it directly or by way of a computer first?

How much are you planning to sell these for, and is there a minimum order quantity?

Thanks,

Boon,

A list of compatible hardware, would be VERY helpful. Can you come up with an exact model of computer / bluetooth hardware / bluetooth stack / operating system / operating system updates (i.e. .net framework 3.5) that will GARANTEE a QUICK and stable connection between the Wii-mote and Smoothboard?

We are saving people so much money with this system that they can actually afford a brand new computer with the savings, so let's make sure that they buy the right computer and other hardware.

Thanks

James

Project Ideas / Re: use laser pen with some fetured button itself
« on: October 17, 2010, 12:15:03 PM »
I did open up one of my Wii-motes to try this out. You just need a special 3 point star screw driver, which I found easily on ebay. I removed the black plastic window from the front, thinking that this was the "filter" that you and Boon Jin and others have been talking about. I don't know maybe there is another layer that I have not removed yet, but this did not seem to change the Wii-mote's behavior at all.

It did not register laser dots as IR dots, but it still worked with my IR pens. Any thoughts?

If this were to be a workable solution, we would want to reverse engineer an exact "physical" copy of the filter, and put it in place of the IR filter. This might easily get to be more expensive then making a home made IR pen, so there would be no point in doing it, from a cost perpective. Also, we are voiding the warranty on the Wiimote, which we do not have to do otherwise.

General Discussion / Re: Real time animation system
« on: September 21, 2010, 09:49:27 PM »
Hey. This is areally cool looking project. I'm not an animator myself, but I know a little bit about game programming and this is most similar to creating a video game. Forgive me if I tell you things that you already know but, in order for a 3D animated character to be controlled by the wii-remote, or any real time control system, it must be "rigged" with a skelton. I'm not sure if maya has the capability to add "Bones" to an animated character but let me assume for the moment that it does. The length, and the positions of these bones are then connected to some outside input, ussually on screen slider, at first, and the 3D primitives that make up the character are hung of the bones, and they go whereever the bones go. In a very sophisticated system they may also lag behind because the are influenced by a physics system. That is, when we take off in real life, it take a white for our hair to overcome it's inirtia and then be "yanked" along for the ride. Also, if there were some wind blowing, our hair would be influenced, and then there's gravity, etc. One of the toughest things about game programming is that the computer knows nothing about these onless special algorythms (physics systems) are put into place to make the characters and objects act like they are in a somewhat real world, but back to the bones.

The bones, in there turn, do what ever the sliders tell them to do, and then SOMEHOW, you will have to get the Wii remotes accelerometers, buttons and maybe IR point possitions, to connect to the sliders, or Maya would have to provide and API, (application programming interface) to the world outside of the program, or AT LEAST make ever movement of a slider able to connect to a keyboard button, or mouse button / movement. One of your best bets for a program that can help you with this is Glove pie. It can surface all of the data coming out of the Wii Remote, and let you connect it to any keyboard button, or mouse button. Good luck and please let us know of your progress.

Wiimote Desktop VR/Head Tracking / Re: question about general use
« on: September 18, 2010, 11:04:11 PM »
There are programs like, Camera Mouse, that let you use an IR pen with an IR sensing webcam to control your computer. Most modern Windows computers come with a free built in on-screen keyboard, so I hope this give let's you control you "whole computer" as you have requested, but I'm not entirely sure what you mean.

You will find if you try them both, that that Wii-mote white board system works better than the camera based system because the Wii-remote actually processes the image. I doesn't just pass a video stream to the computer, it passes a nice, tight little report about the location of up to 4 IR dots, and the status of all of it's buttons, and accelerometers. Also, because it has the bluetooth wireless connection it is also far easier to place the "camera" anywhere you may need it.

Project Ideas / Re: Help me with (x,y,z) tracking position
« on: September 03, 2010, 01:28:38 PM »
The Wii remote's IR camera has a resolution of 1024 by 720. Obviously, the 720 sound like a problem for the resolution that you are needing here. If you were using more then one along the same dimension, the position of each one would have to be VERY tightly controlled.

Use two wii remotes to track IR dots in 3D space. Join this with Virtual reality to make a 3D musical instrument.

OR.

Hang a projector and a Wiiremote from a ceiling or a tall framework and point it down to the floor. Create a simple video game to help preschoolers learn their letters, numbers, shapes, and colors.

Have the item to be learn floating around on the floor. Ask the little one to find say, the A, or the circles. Create an IR pen like hat for each student. When the Video game detects the the IR dot in the region of the target object, it freezes and does a cool colorful, light and sound celebration.

Say Hi! / Re: Hi

Smoothboard 2.0 or another Wii Interactive whiteboard can be used for this. All you would have to is to put an IR LED at the tip of your finger and a button under your thumb, wire these to a resistor and a small battery pack and you are good to go.

Truly tracking a finger has also been done (well tried) with OpenCV, short for open computer vision, and OpenFrameworks library. I have tried a lot of these web-cam mouse systems though and they are really disappointing. The trouble is that all the computer can do is try to look for a patch of color in the video frame, and your fingertip is the same color as the rest of your hand, and the same color as your face. So the tracking spreads out across your entire hand or your face. It really does not work at all yet. MIT also developed a system based on a colorful glove. I have not tried that, but if you see the glove I think that you would agree that an IR pen glove is far easier to make, and far less "nerdy" looking to use. Ok, it's debatable. It depends on whether you want to look like a BORG or a Clown. :-)

Other / Re: Vishay 6400 for non reflective usage
« on: August 19, 2010, 09:21:52 PM »
All of my IR pens are designed to point the Vishay 6400 directly at the Wii Remote, and I have had no tracking problems what so ever, unless I stand in the way. I like putting the Wii Remote right on top of my projector so that my shadow in the projector beam gives me a guide as to when my body might be blocking the view of the Wii Remote. I have never had the need to use sand paper or any other special treatment, but maybe I'll try that just for the education and fun.

There are MANY demo videos of working with direct detection on YouTube.com and TeacherTube.com. Just search for WBSW, or start with this vid:

Wiimote Smoothboard / Re: Smoothboard 2.0 Release
« on: August 12, 2010, 09:49:49 PM »
Thanks Boon,
I'll be making another video soon. I myself was also a little shocked when I got done posting and realized that I had not covered the smart menu. I would also like to cover the advanced setups too, like button mapping and launching a script. I am still a little fuzzy on how the two Wii mote Whiteboard set up works, where one is big picture and the other is high detail? I have never found a need to set up that way honestly, but I would love to give the program comprehensive coverage if I can.

Whalebone IR and Software, and our front man Doctor Nuclear have created a couple of new videos covering the setup and most commonly used features of Smoothboard 2.0. You can check them out at these URLS:

[youtube]http://www.youtube.com/watch?v=bOHATy7mdr8[/youtube]

and

[youtube]http://www.youtube.com/watch?v=S8sr79yc-So[/youtube]

Please do send any questions or coments directly to me. Boon Jin and the Smoothboard team did not create the script or have editorial control over the content of this video, and if they find that it doesn't reflect well on the dignity of their product I will gladly take it down, but for now.... Enjoy.

Also, if you happen to have or be a teen, taking Algebra 1, or  if you are an adult back in school to refresh your math skills. You might benefit from searching Youtube.com for the code WBSW.

My plan is to cover every important Algebra 1 topic, and then to move on the Geometry and Algebra II, all as Doctor Nuclear. If you know of any games, memory tricks, little known shortcuts, etc relating to math, I would be very grateful if you would email them to me. If I like them, I'll share them with the world, through YouTube and TeacherTube.

Can a PC or Mac pair with a Wii console over bluetooth?

A home brewed Wii might also be able to communicate over the internet. There would be a lot of lag though, probably too much to play a video game.

General Discussion / Re: wiimote board VS commercial products
« on: July 26, 2010, 11:29:39 PM »
PROS:

Automatically creates "Teachable moments" for kids. Since the way that the system works is a little more out in the open, a Wiimote system is bound to lead to questions like: "What's an infra-red camera?" "Why can't I see a light coming from the pen?" "How does bluetooth work?" etc.

If the teacher is savy they will jump on these and share a lot of knowledge.

The expensive parts of the system should last longer, since they are not touched everyday by the users. This should lead to even more cost savings.

CONS:

The wii-remote is attractive to teen-aged thieves.
Sensitive to sun-light. Some classrooms need to install black out curtains.
