Cursor jumping around?

If you have this problem, or during calibration the four calibration marks seem to click themselves, it highly likely that there is too much infrared light in the room. When using SmoothBoard, you can easily check this with their calibration assistant. At the bottom of the image to the left, it says, "IR dots". There should not be any number by this until you use your pen. Try clicking on your projected image (with the software running), and look at the "IR dot" count. It should show "1" when you click and nothing when the pen is off. You will also see a little dot on the white tracked area. This dot matches where your pen is clicking on the screen - very handy thanks Boon Jin and SmoothBoard! If there are dots floating about when you haven't clicked, you either need to lower/remove the source of the stray IR light or use the software control panel to turn down the sensitivity of the wiimote's camera. To do this you click on "Show settings", then "Wiimote" after which you can experiment with levels. Earlier posts that we have made on this subject are - Fluorescent lights, Crazy mouse.
