Problems solved by technology
[0003] However, in paper-screen synchronization, due to the inconsistency between the writing area of the handwriting device and the display device in terms of size and specification, the handwriting displayed on the screen is prone to font deformation, cannot track and display the writing area near the pen tip in real time, and cannot adjust the handwriting at will Size and other issues
These problems will greatly affect the user's experience in the writing process and hinder the wide application of paper-screen synchronization technology

Embodiment Construction
[0074] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0075] A method for consistent display of handwriting in paper-screen synchronization, such as figure 1 shown, including the following steps:
[0076] A) Initialization:
[0077] First, place the physical paper on the tablet, so that the four corners of the physical paper and the four corners of the data collection area of the tablet remain fixed and coincident throughout the writing process;
[0078] Then, connect the tablet and the display device, the display device obtains the device size specification information of the tablet, and according to the device size specification information, the display device creates a virtual paper, and the length and width of the virtual paper are kept in the same proportion as the size of the writing paper;
[0079] Next, neatly arrange rectangular boxes on the virtual paper as display reference ...

The invention relates to the technical field of teaching appliances, and discloses a method for consistent display of handwriting in paper-screen synchronization. First, initialize, place physical paper on a tablet, connect the tablet and a display device, and arrange a rectangular frame on the virtual paper As the display reference information, set the scale factor of the virtual paper and the physical paper and the area position displayed in the current window; then, receive the pen tip position information collected in real time by the handwriting device, compare the pen tip position information with the reference rectangle position data, and based on the comparison result Continuously adjusts the display area, tracking the pen tip position and centering the display in the relevant area where the current pen tip is located. The method for displaying handwriting consistency in the synchronization of paper and screen of the present invention senses the position of the pen tip on the physical paper in real time during the writing process, and displays the written handwriting on the screen in a consistent manner. The handwriting does not produce deformation, and the size of the displayed handwriting can be adjusted at will.
Description
technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a method for consistent display of handwriting and handwriting in paper-screen synchronization. Background technique [0002] With the rapid development of electronic information technology, paper screen synchronization becomes possible. The so-called paper-screen synchronization means that while the user is holding an ordinary pen and writing on ordinary paper, the electronic handwriting device perceives the user's handwriting process and results in real time, and synchronously displays and saves the handwriting data. Compared with traditional electronic handwriting devices, the advantage of paper-screen synchronization is that it fully conforms to the writing habit of hand-eye coordination, that is, during the entire writing process, the user's visual feedback is brought by the traces of the pen in the hand left on the paper. Instead of hand-eye separation during w...
