ABSTRACT:
An improved electronic whiteboard is provided. The improved electronic whiteboard includes a plurality of toggle switches along a vertical side for drawing vertical straight lines across the electronic whiteboard and a plurality of toggle switches along a horizontal side for drawing horizontal straight lines across the electronic whiteboard. When some or all the switches along the vertical side are turned on, vertical straight lines are drawn across the electronic whiteboard. Likewise, when some or all the switches along the horizontal side are turned on, horizontal straight lines are drawn across the electronic whiteboard. The intersections of the vertical straight lines with the horizontal straight lines form a plurality of grid cells. The electronic whiteboard contains means for determining the location of these cells.
