Using the Software

To use the software, find a place to mount your Wii remote so that the camera can see your display. The camera has a field of view of 45 degrees. Keep this mind and try to position the Wii remote as close as possible while keeping your entire screen in view of the camera. You can use the "Visible IR dots" feedback to test whether the Wiimote can see the whole display. Activate the marker around each corner of the display to check visibility. If it can see the dots, the diagnostic should respond. Start the calibration, and activate the LED at each crosshair location. It should automatically move to the next crosshair. Once you have done all four, the calibration screen should disappear, the IR pen should now control the mouse cursor, and you can start using your interactive whiteboard display.

The tracking quality is highly dependent on the placement of your Wii remote. If it is too far away from the screen or at too much of an angle, the camera does not have a good view and the tracking will be poor. You can use the Tracking Utilization diagnostic after each calibration to evaluate whether your Wii remote placement is good. The higher this number is, the better the tracking will be. Getting this value to be 100% is extremely difficult in any useful configuration since this would require that the Wii remote be directly in front of the screen. However, if utilization is below 50%, you should consider repositioning the remote. You will also need to be careful not ...
