发明名称 Method for erasing on an electronic writeboard
摘要 A method for erasing writing on an electronic writeboard includes the steps of describing an eraser as a mask and monitoring movement of the eraser over the electronic writeboard. When the mask overlaps with writing on the electronic writeboard, erasing of the writing within the mask is performed. The shape of the mask is adjusted to compensate for the speed at which the eraser is moved over the electronic writeboard.
