UniBoard is Now Free

In the past I've shown off this great program for working with tablets or with a Wiimote whiteboard called Uniboard. The problem was that Uniboard seemed to be dead. There had been no updates or tweets for months (maybe a year). I figured it was a piece of great software that would just fade into non-existence.

Well, yesterday I went looking for it again. I had observed a colleague of mine teaching yesterday and realized that even though it wasn't being updated that he could definitely use it. Well, apparently last week Uniboard went Open Source. It is now called Sankore and is totally free. Warning, the page is all in French. Here's a direct link to the download page.

The free version used to have a nag-screen on every page, it's gone now. The screen-capture tool had a watermark in the recording which is also now gone. I can whole heartedly recommend this program. Whether you need a tool to help present lessons in class or you want to record lessons for reverse lecture you should check out Sankore.

Teacher TechBites Ep 013 - Wii-Uniboard

So, in episode 12 I showed off Uniboard. In this episode I show that it functions with the Wiimote Whiteboard. This really does make it possible to get most of the functionality of a traditional Interactive Whiteboard at a fraction of the cost.

Teacher TechBites Episode 012 - Uniboard

Uniboard is basically a whiteboard. That's really all there is to it. I discovered it on my quest to get the coolest parts of an Interactive Whiteboard without the corresponding price tag. At one point I used the Wiimote option, but now I go with the wireless tablet device.

Stuff to Know

• Will respond to pressure sensitive writing
• Has a built in web browser, but you can only write on static pictures of the pages
• Will allow you to record whatever ends up on the whiteboard and audio recorded from a microphone
• Can import power point and pdf files, which you can annotate
• Includes a number of built in Apps and you can build your own apps to use as well
• You can download Flash apps and embed them in your presentations
• Free version has a pop-up on every page. It appears every time you change pages, so if you go back to a previous page it returns.

Wiimote CPR Trainer?

Wow, this is really cool. Some smart people (Senior engineering students at Univ. of Alabama) out there have written a program to use the accelerometer in a Wiimote to help train people to do CPR correctly. The program is not available yet, but should be on the American Heart Association webstie in early fall 2009.


What makes this really cool is that it is a perfect example of an inquiry based project. While it was developed by seniors in college it could probably have been done by high school students. The skills needed to create this would be within the grasp of students I've had. It makes me wonder what other problems could be solved with the accelerometer in a wiimote...

For those interested in cool applications of Wii technology:

• Wiimote Interactive Whiteboard
• Drive a 15-ton Crane
• Fire Fighting Robot
• Nunchuck to Arduino

Wiimote Interactive Whiteboard

Well, it's been all over the net for a couple of years now so I figured it was about time to jump on the bandwagon. If you haven't heard, you can use a Wiimote, the controller from a Nintendo Wii, as the heart of an interactive whiteboard. The whole technology was developed by Johnny Chung Lee.

Warning, Science Content:
Basically, the Wiimote has a camera in the front that looks for infrared light sources. When used with a Wii the IR lights are positioned atop your TV and the Wiimote "sees" where the lights are relative to the camera. When used as a whiteboard we reverse the set up. The camera (Wiimote) is kept stationary and the IR light moves. All the Wiimote does is look for relative motion. It doesn't really matter which moves, the IR light or the camera. The Wiimote communicates what it "sees" with the Wii through Bluetooth. Yes, the same Bluetooth that phones and computers use.
End Science Content

Anyway, I tried about a year ago with a Wiimote I borrowed from a student, but I wasn't able to find enough time during the school day to make it work. Since that time I've gotten my own Wii. A couple weeks ago we had a snow day, so I thought I'd give it a try. About three minutes later I was done!!! Apparently things are much easier now.

I didn't have an IR pen light yet, so I used a regular remote control (for a TV/DVD player or whatever). A remote works for proof of concept, but you can't use it to write. Remotes actually flash the IR light when in use, so at best you get a dotted line.

Here's what I've learned:

You should set your screen resolution to no more than 1024x768. This is the resolution of the camera in the Wiimote. You should also check out and join the Wiimote Project. This site is a great resource for resolving any trouble you may have.

You need a really bright IR LED to make this work. I had a bunch of IR LEDs laying around, but only one that was bright enough to be usable. The one that was recommeded by Johnny Lee is the Vishay Semiconductors TSAL6400 (I got mine for $0.30 from Mouser). You can buy commercial pens or find instructions on the net to make your own. So far I've only made my own.

Mac OS X - I have a MacBook, so naturally I got started with it. It has built in Bluetooth. I downloaded some free software and followed the directions. Really the longest phase was the downloading (which really didn't take that long).

Links:

• The Main Software: There are a couple different OS X options, but this one seems to be the popular one.
• Magic Pen: Free program that allow you to write/draw on the screen. It takes a little getting used to to use this seemlessly in class, but not too much.
• DarwinRemote: Not needed, but you may want it. This allows you to use the Wiimote as an "air mouse". It will also log data from the 3-axis accelerometer that's built in. Really a must for a physics teacher.

Windows XP - My school is about 98% Windows so I've spent a little time figuring out how to use the whole system on Windows as well. I have no idea how well it works in Vista or Windows 7. The first thing to know is that you need .Net 3.5 or later. You should install that first.

Links:

• Wiimote Connect: This is a must. In Windows you seem to have to re-add the Wiimote every time you set it up. That means you have to remove the old entry for the Wiimote from the stack and then find it again. Wiimote Connect does this for you automatically. You cal also set it up to launch another program for you once it connects.
  
• Smoothboard: There are many different windows options. So far this is the only one I've played with and it seems to work.
• LinktivityPresenter: Free program that gives you tools to write/draw on the screen. It will also save a screen shot with a simple onscree button push.
• Wiimote Analyzer: Again, you really only need this if you teach physics. You must be a member of Wiimote Project to see the download link.

OK, I've rambled enough. I guess I will do another blog post explaining how to set it all up in your classroom. If you have a Wii and want to give this a try all the links you'll need should be above. You may also need a Bluetooth adapter if you don't have it built into your computer. I've read that not all Bluetooth adapters work, so you may want to check out the Wiimote Project prior to picking one up.

If you're in Michigan you may also want to attend the 2009 meeting of the Michigan Association for Computer Users in Learning. John Sowash will be giving a presentation on his use of the Wiimote Whiteboard in his classroom.
