There is clapping, cheering, and laughter from the audience for this TED talk, in which innovator Johnny Lee demonstrates how to turn a Wii game remote into a trendy teaching tool. Lee is highly motivated to bridge the divide between those organizations that can afford to experiment with the cutting edge of technology and those who can only sit back and watch.

In this video, Lee demos how to create an affordable interactive whiteboard by taking advantage of the “high-performing infrared camera” that is in the tip of a Wii controller. He combines the motion-sensing camera of the Wii with a $50 infrared pen (available from Radio Shack)—you just have to see the video to appreciate it.

Since posting this idea on his website, there have been over half a million downloads.

“Teachers and students around the world are already using this.”
