Problems solved by technology

[0005] But the existing handwriting erasing method is mainly used in electronic blackboards, mobile phones and other liquid crystal screens or handwriting devices with other screens, and when performing handwriting erasing on these devices, there are mainly defects as follows: handwriting cannot be generated Objects, but those that can generate handwriting objects for handwriting need to detect handwriting by establishing complex algorithms such as circumscribed rectangles, which makes the operation time long and cannot realize the real-time display of the erasing effect. In addition, the applicable equipment types have relatively large limitations. , and has an inefficient

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0030] Such as figure 1 As shown, the embodiment of the present invention provides a method for deleting handwritten stroke information input by a user on a handwriting device, including the following steps:

[0031] Step 1, the handwriting device obtains the user's current action;

[0032] Step 2, judging whether the current action is an erasing action, if yes, perform the next steps, otherwise, jump to step 11;

[0033] Step 3, the display device saves the original writing track from the memory, and the handwriting device saves the newly added erasing track;

[0034] Step 4, selecting a point...

Abstract

The invention discloses a method for deleting handwritten stroke information input by a user on a handwriting device, and relates to the technical field of information science. The method is as follows: After receiving the handwritten information input by the user and identifying the type of information as erasing information, by comparing the existing information with the information of this track, filter out the strokes that need to be erased and delete these strokes, and display The device will display the modified handwriting information in real time. It has the following advantages: the handwriting device has a variety of working modes, and this erasing method can automatically judge whether the current erasing action is based on the user's input method; after reading and saving the erasing track, it can judge the handwriting passed by each track , so as to erase the corresponding strokes to meet the erasing needs of some users; at the same time to realize the erasure of the data, the erasing effect of the strokes is displayed on the ink screen interface in real time, with fast display speed and high erasing efficiency.

Description

technical field [0001] The invention relates to the technical field of information science, in particular to a method for deleting handwritten stroke information input by a user on a handwriting device. Background technique [0002] In the field of education, after-school exercises are an essential part of consolidating knowledge and applying what you have learned. With the development of technology, paperless homework and exercises in the field of education are gradually promoted. [0003] It can greatly improve work efficiency, because unlike LCD screens, ink screen devices will not harm students' eyesight. Therefore, in the field of education, the use of ink screen equipment for homework distribution, practice and correction has been widely promoted, greatly improving work efficiency. [0004] Because the tablet computer has rich functions and is convenient for teacher-student interaction, it is suitable for the teacher to use the tablet computer. In order to improve t...
