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 objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, and not 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 current action of the user;

[0032] Step 2. Determine whether the current action is an erasing action, if it is, then perform the subsequent steps, otherwise, skip 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 erase track;

[0034] Step 4. Select a point m f...

Abstract

The invention discloses a method for deleting handwriting stroke information inputted by a user on a handwriting device, which relates to the field of information science and technology. The method comprises the following steps of after receiving the handwritten information input by the user, identifying the type of the information as erased information, comparing the existing information with thetrack information of the item, selecting the strokes to be erased and deleting the strokes, and displaying the modified handwriting information in real time by the display device. The invention has the following advantages that the handwriting device has a plurality of working modes, and the erasing method can automatically judge whether the current erasing action is an erasing action or not according to the input mode of the user; after reading and saving the erasing tracks, the handwriting passing through each track can be judged, so as to erase the corresponding strokes and satisfy the erasing requirements of some users; at the same time, the erasing effect of the strokes is displayed on the ink screen interface in real time, and the display speed is fast and the erasing efficiency ishigh.

Description

Technical field [0001] The present invention relates to the field of information science technology, and 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 has been learned. With the development of science and technology, paperless homework and exercises in the education field are gradually promoted. [0003] It can greatly improve the work efficiency, because unlike the LCD screen, the ink screen device will not harm the eyesight of students. 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] Since the tablet computer has rich functions and is convenient for teacher-student interaction, it is suitable for the teacher to use the tablet comp...
