Abstract
There are provided a method and an apparatus for scroll information input in an electromagnetic induction way. The method comprises steps of: definition of scroll bars, where a horizontal scroll bar and a vertical scroll bar are defined for an electromagnetic board by means of a controller of the electromagnetic board; implementation of scrolls, where virtual scrolls for the scroll bars of the electromagnetic board are achieved based on positional changes of an electromagnetic pen over the horizontal scroll bar and the vertical scroll bar of the electromagnetic board; and mapping of scrolls, where the virtual scrolls for the scroll bars of the electromagnetic board are mapped into scrolls for scroll bars in a computer by means of the controller.
