Electronic screen copying and handwriting exercising device

Abstract

The invention discloses an electronic screen copying and handwriting exercising device, which belongs to the field of electronic screen copying and handwriting exercising utensils, so as solve relatedproblems that a touch electronic screen device such as a mobile phone or a tablet computer is used as a copybook source, the screen surface is used as a supply surface of the copybook, and real paper-pen copying and handwriting training is carried out. The device is characterized by at least comprising a hand supporting plate for supporting a hand holding the pen; with the help of a supporting body, through below supporting or side supporting or upper hanging, a hanging part is formed; the space below the hanging part is used for accommodating a flatly-placed electronic screen device; the supporting body is an accessory device beyond the hand supporting plate or a component of the hand supporting plate. The hand holding the pen can be constantly and firmly supported, interference to the touch screen can be reliably blocked, the copybook displayed on the screen can be ensured to have a good penetration and display effect on the writing medium, and the technical scheme is simple and easy to do, and the price is low.

Description

technical field [0001] The invention belongs to the field of tools and supplies for copying and practicing calligraphy on an electronic screen, and is used to solve the related problems of using touch electronic screen devices such as mobile phones and tablet computers as copybook sources to conduct real "pen and paper" copying and writing training. Background technique [0002] In today's era, electronic screen devices such as mobile phones and tablet computers have been widely used in a large number of applications. They are powerful, flexible, portable and easy to use. If the screen is used as a copybook, it can realize "one screen for all purposes". By retrieving from the storage device or downloading from the Internet, copybooks of any type, content and font can be easily searched, presented and applied. The size adjustment is also easy to realize, just move your finger to swipe the screen. By taking pictures of existing copybooks or calligraphy works, it can be digiti...

AI Technical Summary

Problems solved by technology

There are two problems: one is that there is a big gap between finger writing and "paper-and-pen" writing, and it is difficult to practice handwriting; the other is that the "handwriting" of finger writing requires a large However, the screen area of ​​a mobile phone is narrow and limited, and usually only one or two characters can be practiced per screen. Although the screen of a tablet computer is larger, it cannot accommodate a few characters, resulting in low efficiency in practicing writing. Moreover, a normal-sized pen Copybook, can't practice writing with fingers at all

[0004] If you plan to use a real brush or pen to write on the screen, there will be two problems that need to be solved: one is that the hand holding the pen will inevitably touch the touch screen of the mobile phone or tablet computer, which will disturb the screen and interfere with the touch screen. Stable presentation of copybooks. Second, the screen of a mobile phone or tablet is not an ideal or normally usable writing medium. Writing ink will pollute the screen, which is very inconvenient to clean. Moreover, writing on a hard screen is not as practical as it is in practice. Compared with writing on soft paper, the hand feel is completely different

[0006] As for the problem of blocking the disturbance of the screen, one solution is to block the disturbance of the touch screen by covering the mainstream capacitive touch screen with a light-transmitting conductive film or an electrode film, but this solution requires a tight connection between the barrier film and the screen. Otherwise, the barrier will not be complete, or the film itself will become a source of disturbance, which will make it extremely difficult to control the bonding and disengagement of the screen and the barrier film. If the film is directly pasted on the screen , it will make the touch screen invalid and affect the normal use of the device

Another solution is to cover the screen with a light-transmitting medium layer to block the possible disturbance caused by the hand holding the pen. However, according to experiments, for most current touch screens, a light-transmitting medium layer with a thickness of at least 1.5 mm is required. Can block disturbance, and with the improvement of touch screen sensitivity, the required medium thickness needs to be further increased

The problem brought about by the thicker light-transmitting barrier medium is that if you directly copy on the medium, there will be a large distance and different layers between the screen surface where the copybook is displayed and the medium surface where the pen is written, which will cause confusion when copying. This is unacceptable, and if you want to cover another layer of light-transmitting paper on the medium and trace it on the paper, the copybook will be blurred on the paper due to the large thickness of the light-transmitting medium. The see-through effect on the screen becomes worse, even blurred and difficult to describe

The first scheme is too cumbersome to apply, and the second scheme has a bad writing experience, so it is not advisable
