Abstract

The invention provides an annotation erasing method and a device, and electronic equipment, and the method comprises the steps: obtaining annotation contents and a corresponding timestamp when an annotation operation is received; obtaining a current labeling state; and according to the timestamp and the current annotation state, carrying out erasing operation on the annotation content. According to the method and the device, the annotation content is erased according to the received timestamp and the annotation state, and an eraser function in the electronic whiteboard or a handheld eraser matched with the electronic whiteboard does not need to be used for manually erasing the annotation by a user, so that the operation convenience is improved.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a marking erasing method, device and electronic equipment. Background technique [0002] Interactive electronic whiteboards are widely used in meeting rooms and other application scenarios due to their powerful functions. For example, the annotation function of electronic whiteboards provides great convenience for explanations, and has become a very important function among the many functions of electronic whiteboards. [0003] However, sometimes the marking operation on the electronic whiteboard is only an auxiliary expression, not the focus of the demonstration, and does not need to be saved, and the marking needs to be erased afterwards. In the related technology, the markup is erased by using the eraser function in the electronic whiteboard or by using a hand-held eraser adapted to the electronic whiteboard. This erasing method requires the user to manually erase, whic...
