[0034] Specifically, it can be understood that for a smart whiteboard, the width of the smart whiteboard is divided into k parts to form k areas to be displayed, and the width of the areas to be displayed remains unchanged. Also, the length and width of the kth area to be displayed remain unchanged.

[0035] S620, sorting the initial display files in descending order based on the priority scores, obtaining the sorted initial display files as final display files, thereby obtaining a final display file list J={J1, J2, ..., J e , …, J h}, J e This is the final presentation file.

[0036] S630, Get J e List of pages included K e ={K e，1 , K e，2 , …, K e，x , …, K e，q（e）}, K e，x It's J e The xth page contained, x ranges from 1 to q(e), q(e) is J e The number of pages included.

[0037] S640, if q(1)+q(2)+…+q(e)+…+q(h)≤k, change J1 to J h The included pages are listed in descending order according to their corresponding priority scores. k Otherwise, execute S650. Specifically, if q(1)+q(2)+…+q(e)+…+q(h)≤k, that is, each to-be-displayed area displays one page, all initial display files can be displayed on the smart whiteboard, and the initial display file with the highest priority score is displayed on H1.

[0038] In an exemplary embodiment of the present invention, k=4, H={H1, H2, H3, H4}, J={J1, J2}, K1={K 1，1 , K 1,2},K2={K 2，1 , K 2，2}, K 1，1 On H1, display the K 1，2 In H2, K 2，1 In H3, display the K 2，2 Screen projection display in H4.

[0039] S650, get y, change J1 to J y The included pages are listed in descending order according to their corresponding priority scores. k Display, where q(1)+q(2)+…+q(y)≤k, and the value range of y is 1 to h-1. Specifically, if q(1)+q(2)+…+q(e)+…+q(h)>k, obtain y, and project the first y final display files.

[0040] In summary, obtain the list of areas to be displayed of the smart whiteboard, sort the initial display files in descending order based on the priority scores, obtain the sorted initial display files as the final display files, thereby obtaining the final display file list, obtain the page list corresponding to the final display file, and based on the page list, project the final display file for display.

[0041] Furthermore, after S650, it also includes:

[0042] S660, obtain the number a of unoccupied display areas, and when a≥q(y+1), set J y+1 The included pages are displayed.

[0047] In summary, the first side length of the final display file is obtained based on the priority score, so as to determine the area of ​​the display area of ​​the final display file, and the font size of the final display file changes according to the area of ​​the display area. The higher the priority score, the larger the font size of the final display file, so that employees can pay attention to files with high priority scores in time.

[0048] Specifically, S600 also includes:

[0049] S601, obtaining a preset priority score fixed time length correspondence relationship, and obtaining J based on the preset priority score fixed time length correspondence relationship. e The corresponding fixed duration M e The preset priority score fixed duration correspondence relationship is a one-to-one mapping relationship between the preset priority score and the fixed duration. In the preset priority score fixed duration correspondence relationship, the higher the priority score, the longer the fixed duration.

[0050] S602, obtain K e，x The number of characters P e，x , so as to obtain K e The number of characters contained .

[0051] S603, based on P e and the preset average reading speed, obtain K eCorresponding reading time L e .

[0052] S604, based on M e and L e , get J e Presentation time on the smart board.

[0053] In summary, the preset priority score and fixed time correspondence is obtained. Based on the preset priority score and fixed time correspondence, the fixed time is obtained. Based on the number of characters and the preset average reading speed, the reading time is obtained, and thus the display time on the smart whiteboard is obtained. The higher the priority score, the greater the probability of a longer display time, so that employees can notice the initial display file with a high priority score.
