Low-Cost Multi-point Interactive Whiteboards Using the Wiimote

Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

Software
The calibration and mouse cursor emulation software is available for you to download and try yourself. Note: My mouse emulation code isn't perfect. If any of you are programmers and can get it working with Alias Sketchbook, drop me a line.
1. Connect your wiimote to your PC via Bluetooth. If you don't know how to do this, you can follow this tutorial. I've been told it works with other Bluetooth drivers, but I have not tested them myself. You can report compatibility issues on the SourceForge:WiimoteWhiteboard - Help Forum
2. Download the Wiimote Whiteboard sample program (that is attached to this post.) Please read the "READ ME.txt" file first! Make sure your wiimote is connected via bluetooth, and then run the ".exe" in the main folder. NOTE: Good placement of the wiimote is key to good tracking. View the README for more info.

Multitouch: The multitouch demos are custom C# DirectX programs (which is the second attachment.)   You may download the source code, but this is provided for developers without support or documentation. The code is built on top of  this Wiimote library. Unfortunately, multi-touch capable applications are currently extremely rare. Hopefully, that will change as more developers explore its potential.

Building pens: Here is a simple schematic of the light pen. You also might be able to jump start your experimentation by retro-fitting a mini keychain light with an IR LED. This website seems to sell IR keychain lights that might be ready to use, but I haven't tested them. I'm currently looking into manufacturing and selling IR pens, but this may take several months.

Mac/Linux Versions: A Mac version is almost done, I'm still battling some big bugs. I'm new to Mac dev, so bear with me. You can subscribe to updates at my Project Blog [procrastineering.com] . A linux version will not be created by me. I am putting out a call to the open source community for this and have created a Source Forge Project for the Wiimote Whiteboard. Please help spread the love. A lot of people are already waiting to use your software.

A visit to this project's FAQ and Advanced Discussion post may be very englightening.

This website seems to sell IR keychain lights that might be ready to use, but I haven't tested them.

After some difficulty constructing my light pen I ordered the cheapest infrared keychain light made by that site for about 20 bucks after shipping. It works quite well, but it is smaller and might not be as comfortable to hold for long periods of time as a homemade pen. The light is fairly directed, and it didn't work very well facing forward, but I calibrated it holding the light facing toward me, and it works like a charm. It is quite smooth (on my 17 inch monitor), and I was able to calibrate it as a pointer across the room from my wiimote without having any problems with the light dissappearing(like my homemade pen did). That's my two cents for anyone too lazy(or unsuccessful) to create an infrared pen, and too impatient to wait for them to be sold: it works, it's bright, but the small keychain form factor and high price may be undesireable for practical use.

hello,

I think your ideas are great and have wonderful applications for the classroom.  My problem is we are using Macs.  Can you do the same things using a mac platform???

Be Well

Hi,

If you have this error, 0xc0000135, most probably you do not have the .net framework required to run the software.

For the Smoothboard software, you will need the .Net 3.5 Framework which can be downloaded from here:

Hi,

As I have posted before, you can take a look at the following chapter in Brian Peek's book
http://books.google.com/books?id=d1QC69atuocC&lpg=PP1&dq=brian%20peek&pg=PA377#v=onepage&q&f=false

Has anyone considered having the program read two LED sources from the pen, one to take constant position (one that would stay on the entire time) and another that could be controlled by a momentary switch that would count as a left click? This would mean that in addition to having the camera pointed at the screen and being able to see the true cursor position at all times, the Wiimote could point at you, and you could wave the light pen around in the air and be able to click it at you please. This shouldn't be terribly difficult to implement (if its not already) since it can already tell how many IR sources there are, if there was one on the screen it would count as cursor movement, and if there were two it would click. If I was a little better versed in how to use a program to compile C# I would try it myself.

Hi,

It is not difficult to develop this but it may not be practical in actual usage.

This is because there will be chances that one of the IR dot could not be detected by the Wiimote. Also, if the two IR LEDs are placed close together, the Wiimote may resolve this two dots as only a single IR souce.

If the two IR LEDs are placed further apart, then the way the user hold the pen may block the second IR LED.

Actually, there are many other more reliable ways that you can use to use trigger the left aclick and even the right click. You can have an always-on IR LED at the tip of a pen and set Smoothboard Cursor Control to Motion-only mode.

Hi,
I have some questions regarding the whiteboard application, is it possible for this application to be modified to work with XBOX controller instead of wiimote or is there anyother alternative to wiimote?

secondly is this code modifiable for 64 bit processors?

i'd reeally appreciate your help

thanks
