magnify the document on the base plate and display
a sharp image. You may now place your hand on the
document. VisioBook will magnify your hand. The
surface of your hand is in focus while the characters
on the document are blurred. The same may happen
when you want to ll in a form. Instead of sharp
letters, you may see a focused view of the back of your
hand holding the pencil. If you pull your hand from the
document, the characters become sharp again.
Writing is easy when you adjust the camera angle
and use the auto focus button.
