Abstract
The disclosure discloses a method for erasing a writing path on an infrared electronic white board, the method including: adding data points to a writing path to obtain a complete writing path in which the distance between any two adjacent data points is no more than an erasing distance corresponding to a selected erasing mode; determining an erasing area according to an input erasing path and the erasing mode; and erasing those data points on the complete writing path, which lie in the erasing area.
