Low-Cost Multi-touch Whiteboard using the Wiimote

17 04 2011

Using infrared (IR) light pens and the Wii Remote, it is possible to create very low-cost multi-point interactive whiteboards and multi-point tablet displays. Johnny Chung Lee, Carnegie Mellon University. The software can be downloaded at johnnylee.net

@blackjet34 LOL, Wiimote detects the IR, and send messages to the software on PC as coordinates, not visually or IR cam. So, theres no IR colors difference. (Colors are just sign…)

Maybe we should call this technology “The Johnny Wii.”

@rjlewis68 Java Wii board is a good free program that autoconnects the Wiimote. It does not mention screenshot capture in the features list. You can do screen capture by hold your alt key and pressing screenprint This saves the screen to your clip-board. Smoothboard has save to file screen capture and it and costs only $29.99. Message me or check out my vids. if you would like more info.

@reecedaw RE: Can this work with a normal TV? In most cases yes, but BE CAREFUL. Most TVs these days have a VGA or HDTV input that are compatible with laptop, and Desktop computer hookups, HOWEVER, you would want to be very careful not to scratch your TV screen with you IR Pen as you try to write on it. I know that projectors are expensive but the really are great, tons of uses. They can be easily carried anywhere.

Mine highlights everything on my desktop, is it because I’m using windows 7 instead of windows XP? Also, I get no white screen after calibration, just my desktop.

Johnny, great video. Thanks for the tips. For clarity, without the software support in place, can this information be SAVED digitally after drawn out? To me that is the primary benefit of the interactive white board. Do you know of any freeware that enables that? Thanks in advance for the follow up.

@Bernardcruz20 The second mouse button is a little tricky, but you don’t often need it when you are presenting in front of a class. If you do, these is a software called smoothboard 2.0 which allows you to pop up a right click menu by holding the left click button in one place for about 2 seconds. Message me if you would like more info.

Very cool! I like finding cheap hacks to what use to be expensive problems! The WiiMote is glorious– you can also use the nunchuck as a cheap accelerometer/ joystick (fun when playing with my Arduino and some servos)!
