Technical Field

The invention belongs to the field of instruments for writing and drawing, and particularly relates to a remote guidance Chinese painting copying device and a using method thereof.

Background

The best method for learning the traditional Chinese painting is copying, and the method for learning the traditional Chinese painting is different from the method for learning the western painting, and the copying is the most important method for learning the traditional Chinese painting to a certain extent. The copy is called as face to the real trace imitation and the cover paper copy is called as copy. The purpose of imitation is to learn and comprehend the skill and expression technique of writing and writing of others, to understand and master the traditional method and law of Chinese painting, and to lay a foundation for sketching and creating. Distance education is an education form which adopts various media ways to carry out system teaching and communication connection, and is education for delivering courses to one or more students outside a campus. Modern distance education refers to education in which courses are delivered through audio, video and computer technologies including real-time and non-real-time, and the development of computer technologies, multimedia technologies and communication technologies, especially the rapid development of the internet, makes the means of distance education have a qualitative leap and become distance education under the high and new technical conditions.

The application with the application number of CN201920198808.3 discloses an integrated interaction device, which comprises a shell, a display screen, a projection device, a camera and a host, wherein the host can receive live pictures or written videos of teachers through a network and display the pictures through the display screen, the host can project the pictures on paper through the projection device so as to be convenient for a user to copy, and videos can be shot in real time for interaction in the writing process; although the interaction equipment facilitates remote communication, the changes of hardness, softness, lightness, urgency and slowness of the traditional Chinese painting pen can not be intuitively sensed only by remotely watching videos and images for guidance, students can not have personally-on teaching feelings, and meanwhile, the drawing defects of the students can not be intuitively analyzed by data.

Application number is CN 201821715438.8's application document discloses a recess copybook pen, be provided with the recess of font profile on the copybook board, front end at the pen-holder is provided with the bulb, the bulb can be according to the order of a brush and remove along the font recess that has the inclined plane during use, standardize and write the route and with the pen order, above-mentioned recess copybook pen cooperation is though can be direct standardize user's habit of using with a pen, but the recess copybook needs the shaping of processing in advance, can not change to teacher's teaching progress requirement, the recess form of above-mentioned copybook only is applicable to calligraphy practise calligraphy simultaneously, because the thickness of lines, length change and alternately more in the drawing of chinese painting is used, it is difficult also to make the recess effect well.

In summary, the existing chinese painting drawing learning devices cannot meet the requirements of remote chinese painting teaching guidance, cannot give the students who do remote learning to learn the drawing skills with their hands, and the students can only learn by themselves according to videos or pictures, and cannot intuitively feel the changes of stiffness, softness, lightness, urgency and the like of the chinese painting pens during learning, and the students cannot have the experience of being personally on the scene in teaching, and cannot intuitively analyze the own drawing defects with data, so that the devices need to be improved in the aspects.
