Handwritten Chinese character stroke confirmation method for carrying out similarity matching on the basis of characteristic matrix

The invention discloses a handwritten Chinese character stroke confirmation method for carrying out similarity matching on the basis of a characteristic matrix. The method comprises the following specific steps: (1) establishing a stroke feature set based on writing direction, topological relation and shape for a certain Chinese character which is given as criteria; (2) recording the Chinese character writing trajectory of a user by utilizing a digital handwriting platform, analyzing and processing to obtain user Chinese character features, and establishing user Chinese character stroke feature matching space which is uniform with standard Chinese character stroke features for the user Chinese character features; (3) judging total similarity between certain stroke of the Chinese character and a standard Chinese stroke by taking the standard stroke feature set; and (4) if the total similarity is higher than a certain threshold value, finishing stroke matching, and otherwise, judging that matching fails and the stroke is wrongly written. One-to-one corresponding relationship judgment of a user handwritten Chinese character stroke and the standard Chinese character stroke can be realized, so that whether the user handwritten Chinese character stroke is correct can be judged, and the invention exhibits important application value.

Writing practicing method for strengtheningly remembering strokes of Chinese characters

ActiveCN102789710AStrengthen active memoryEasy Quantitative RequirementsTeaching apparatusChinese charactersActive memory
The invention discloses a writing practicing method for strengtheningly remembering strokes of Chinese characters. A copybook used in the method is formed by pieces of paper provided with standard characters, lattices and invisible standard characters, wherein the invisible standard characters are printed in blank lattices by using special printing ink or special ink, the invisible standard characters are invisible before being writing, and only parts (coincident with those of the strokes of written Chinese characters) of the invisible standard characters can be developed. When the writing practicing method is used, the standard characters are copied repeatedly on the copybook, stroke positions of each standard character are remembered, and then the depicting is carried out in the blank lattices; if depicted strokes are not coincident with the strokes of each standard character, the developing can not exist, so that a practicer can find the writing error in real time, the active memory of the brain on the stroke positions of each standard character can be strengthened so as to further change writing habits, the combination of the brain, the eyes and the hands during the writing can be promoted, and the purpose of improving the writing practicing efficiency can be realized.

Environment-friendly repeated-writing paper and preparation method therefor

The invention discloses environment-friendly repeated-writing paper and a preparation method therefor. According to the environment-friendly repeated-writing paper and the preparation method therefor, a hydroxyl protective group is added into a nano bacterial cellulose suspension with excellent characteristics such as high water absorptivity and water retention ability and good water and air permeability, so as to lower hydrophilicity; a staged reaction is carried out under strong base conditions, so that bacterial cellulose reaches moderate water absorptivity and water retention ability, ink can only be present in a surface layer and be clear in writing while the ink is absorbed, and thus, writing, reading and subsequent handwriting wiping are facilitated; then, a scientifically-compounded dispersant is added, and ultrasonic and high-voltage pulse electric field combined dispersion is carried out, so that a stable and uniform modified bacterial cellulose suspension is obtained; finally, the surface of raw paper is coated with the suspension so as to obtain the writing paper with appropriate ink absorbing uniformity and adhesive power and a dense structure, thus, the writing property of the writing paper can be enhanced, and the clearness of writing is enhanced; and waterproofing and oil-proofing actions can be achieved, most importantly, ink marks on the paper can be erased with a cleanser and the paper can be reused for 40 to 100 times under the condition that the performance of the paper is not affected.

Character tracing system and device

The invention discloses a character tracing system and device based on a signal lamp technology. A tablet has prompts for key points such as starting points, end points, inflection points and the like of strokes of characters, and all that is required for writing of beautiful Chinese characters is to pay close attention to or connect the starting points, the end points or the inflection points for tracing. Words of the characters are displayed in signal lamps respectively according to the writing level and the mastering degree. The writing level and the mastering degree can be clearly quantified, and a user can focus on practicing characters which are displayed in red lamps and do not reach the writing standard. Characteristics of colors are fully utilized, the display definition and the learning efficiency are improved, words with different difficulty are distinguished by the colors and grouped separately in a classified manner, the user focuses on words which are not mastered, and the learning efficiency is improved. The system can be in a standalone version or an online version, and requirements of different users are met. A terminal can be an Ipad or a mobile terminal. Crowds, groups and the like can be set up on an online-version platform for learning exchange and conversations among many persons. Own works can be uploaded and downloaded.

Chinese character writing order correction practice device

The invention discloses a Chinese character writing order correction practice device comprising a handwriting recognition analysis processor, a display touch screen, a function case module, a storage module and a loudspeaker. The handwriting recognition analysis processor preloads a handwriting distinguishing system. When handwriting order information transmitted by the display touch screen is received, the Chinese character is firstly recognized, then the writing order information of the corresponding Chinese character is scheduled from the storage module, and then whether the handwriting order information transmitted by the display touch screen is correct is judged through analysis and comparison. If the handwriting order information is correct, character information of "correct writing order" is outputted to the display touch screen; and if the handwriting order information is incorrect, the character information of "incorrect writing order" and the correct writing order information of the Chinese character are outputted to the display touch screen, and the loudspeaker is controlled to emit voice information indicating the correct writing order of the Chinese character. The Chinese character writing order correction practice device is simple in construction and low in use cost so as to correct the actual writing strokes of a learner and enhance his Chinese character writing capacity.
