centre (cross) of each point, the button must be pressed and kept pressed until
the full green rotation is done. The calibration should be done very precisely in
order to get best possible comfort in using interactive whiteboard. If camera was
properly positioned then after calibration the view window will be green.
Otherwise camera position should be corrected (see chapter 3.2).
Attention:
the view window shows the picture seen by the camera. This window is updated after
every calibration. The colorful area inside the window shows the working screen (the picture
shown by the projector) on the area seen by the camera (white rectangle inside the gray frame).
If the camera is set incorrectly, which means it does not “see” the whole working screen, it will
be notified with the color change to yellow (one corner cannot be seen) or red (part of the screen
cannot be seen) and an announcement of the necessity of correcting the camera position. The
board works correctly when the green color is shown. When red color appear then board will stop
operating mouse cursor (the option “Move mouse cursor” will be unchecked) and will work to a
limited extend; camera position should be corrected and calibration repeated. ZOOM in projector
should be set to minimum.
