The method includes the following steps: obtaining first contact points; enabling an erasing mode when a quantity of the first contact points is greater than a preset value; obtaining second contact points in the erasing mode, and calculating an erasing region according to the first contact points and the second contact points; and deleting handwriting data in the erasing region. Using the method for erasing handwriting on an electronic whiteboard provided by the present disclosure can enter an erasing mode rapidly and erase handwriting effectively, thus improving the practicability of the electronic whiteboard."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and device for erasing handwriting on electronic whiteboard","description":"The present disclosure discloses a method, an apparatus and a device for erasing handwriting on an electronic whiteboard.
