Servo Zhai 1 and a plurality of electronic devices 21 belonging to each user, and each electronic device 21, 22 and the temple server i can communicate with each other through the network. Since this embodiment is implemented in a campus, the network between the electronic devices 2 and M and the server 1 is a local area network. The electronic device includes at least a display screen for displaying information, an input device for inputting data by the user, and referring to FIG. 1, the preferred embodiment of the “shared teaching whiteboard of the present invention” includes 15: a network for connecting to a network. It can be a personal computer, a notebook computer, a personal digital assistant, a tablet computer, etc. In this example, the electronic device 22 and 22 are described using a tablet computer as an example, so users can enter information through a stylus. The identity of each user can be a student or a teacher in the classroom. A teaching whiteboard management program and a database (not shown) for storing teaching whiteboard information are installed in the temple server 1 and installed in each electronic device 21 and 22 There is a shared teaching whiteboard program (not shown). The functions and electronic jealousy of each program and the interactive flow between the server and server 1 will be described in the following paragraphs. M can be understood by the client. electronic device starts its hereinafter, the first to be used with the FIG. 2 process will be described. when the start classroom lessons, 201,243,347 set shared whiteboard teaching program in 21, 22 via what _, ..., 5 white As the artist knows, the shared teaching whiteboard program can also be made a resident program. After the shared teaching whiteboard program is started, in step 31, each user is required to log in to the feeder through the network. Each server is stored in the server 1. User information, such as user name and password, is used to verify that the uploaded user information is correct when the user logs in. Second, in step 32, 'When the user logs in to the feeder " reply, download — whiteboard list to Electronic devices 21 and 22. As shown in Figure 6, the whiteboard list 61 contains ίο 15 there are multiple whiteboards 611, 6i2, 613 that are currently online. Here, because this example is planned for the campus for most courses Use, so the database of the server cry will also store the curriculum of each user, so the user logs in to the server cry corresponding download the whiteboard name of the course that the user should be attending at this time is early, so although the same time, but in different classrooms The list of whiteboards downloaded by users is also slightly different. Miao, you are ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Users, the content of the discussion, The whiteboard images corresponding to the Xiangguan whiteboards 611, 612, and 6. Therefore, in step 33, it is measured whether any of the whiteboards 611, 612, and 613 is clicked. If the whiteboards 611, 612, and 613 are clicked in step 33, when selected, execute step 34. If step 33 does not detect the click on the whiteboard 611, 612, 612, step 3 7. κ, in step 34, from 111 healthy white shell material relevant to the download whiteboard name Before the user edits the data edited by this whiteboard, other users can turn on—f-panel drawing Φ 62 (as shown in Figure 7). After that, the user can add lights to the whiteboard picture 62, for example, use a stylus to draw the edge or paste pictures, etc. (described later after bringing to volume). 201243347 "human whiteboard since each user may edit operation, and therefore, in step 35, the shared whiteboard teaching program will periodically update the selected whiteboard (correction on the display of the electronic device white picture on the screen) data so that white screen with other users may be updated editing action (described later volume). Furthermore, since the user might face due to the whiteboard day previously used has been edited or user To gain space to discuss new issues and new - white screen, mesh and, in step 36 from a total of drought teaching program board will regularly update the list from board 6 BU ornament new whiteboard whiteboard in real-time display of the list of all users. on. Furthermore ίο 15 'while the present embodiment has updated at step 35, the selected data and whiteboard whiteboard name # 61', however those skilled in the art as known, the order of steps performed Ding 3-536 designer needs to follow the adjustment, fraudulent claims can be executed simultaneously is not limited to the described embodiment disclosed embodiment. , Then skip to step 37, and then click 丨 Ύ ▲, only detect whether the user has added a new one; the whiteboard screen (referring to the blank white gold; ^, Wang Bai's whiteboard day surface). If it is detected in step 37, go to step 38, and upload the message to open the new whiteboard screen to server 1. Message will include this new white-woo Β data Shang 1 who opened refer to Open "= User name back of the user, allowing other users to more I: two immediate understanding of the new whiteboard is what - the user open 1 ^, '. After the beam, 'use the whiteboard screen added by the user as the selected white handle to help other users ... keep updating the whiteboard data' so that users can instantly edit and edit Xingu right on the whiteboard screen added by Niu V determination step 37 is NO, jumps back to step 33, to a little senses whether the user elected - operation of the whiteboard. 20! 243347, It should be noted that, _ in steps 33 and 37, the user can test whether the user has turned on the whiteboard day and time. However, the order of those who are familiar with this skill ^ Niuyu, 37 can be adjusted according to the needs of the designer. Yes, it should not be limited to what is disclosed in this embodiment. Ancient people pounds with one port to FIG. 3 according to the present embodiment update information boards day whiteboard surface is selected in the preceding embodiment In this consumption is assumed that the user has opened a white 10 15 20, first, in step 350, the embodiment set - first update intervals to determine the time interval between = new whiteboard poor materials. When the _ update interval = is set by the designer, the-update interval in this example is set by taking 5 preset time values (such as 0.3 seconds). : When the user opens the whiteboard screen 62, other users may edit it on the second time, if the user is editing. In order to avoid interruption of the update change, it will cause user's confusion. In order to avoid the occurrence of the situation, in this embodiment, it is set to be used. 2: It is not necessary to update the whiteboard picture 62 until the user edits the whiteboard picture. Thus said heat 62 'towel at step 351, to detect whether there is written on the whiteboard user: bovine :: device (not shown in FIG an action, the user / timer 15 starts when the user to edit this embodiment whiteboard surface 62 Edit an input device such as a stylus to draw on the whiteboard, “㈣Touch” or paste the picture on the whiteboard screen 62 for the user 10 1243347 In addition to stopping the timer in step 352, it is more suitable for editing.

'The users will upload the update data generated by their edit whiteboard actions to the ship. 1, 1 server have the latest, most complete (iv) each white "material, and each user will always downloaded from the server 1 updates the selected whiteboard, whiteboard day so that surface 1,251,015,201,243,347 open in addition to 62 ^ I. Generated by your own editing whiteboard action = 'Updated data generated by other users for the same whiteboard editing whiteboard = will also appear. Therefore, the whiteboard day 62 of each user can be used to: edit the whiteboard actions to express opinions, and other users; perform the whiteboard editing actions on the whiteboard 62, to discuss the results, and the results of these discussions can be real-time _ day at the whiteboard surface for all users of the two ^ ^ user, interactive tools discussed in 'thus increasing the user's effort left a sense of participation, in order to achieve the effect of interactive teaching. Further, L "next to the present embodiment Next, with 4% ΒΒ cool persons in the process of updating η Shang white list 61 set # Α ^ towel in the step of setting a second update interval to determine, - Updates the list of the whiteboard Interval between 61. No .: It can be set by the user or preset by the designer. The new field capture system is preset by the designer, for example, 3 types, the update interval is the second update interval. Steps According to the preset value ^ 'In step 361, the timer starts to count. In this example, it is set to the same—the update interval is performed once when the whiteboard list is new. # The second update interval is a multiple: the example is to said second if the update interval is 3 seconds ^% ^ state counts to 3 seconds and F is ❼ ten de, ^ 2 seconds and so on are all updated. 362 ^ renal step 362 'determines whether the update time of arrival. If it is judged as yes, perform step addition. If the step is judged as j ^, skip back to step 362 to continue to wait until the update time. "Day guard in step 363, 吝 4 generated-whiteboard list update request and upload To serve 13 1243347 server name The update request contains the whiteboard list update request received by π, then the Tianhe service list will update the user ’s whiteboard 4 from the user 乂 Ιπτco, b, and update the data (same as the change of 2_people to this time as the whiteboard) The name body b (and the whiteboard added by the user who belongs to this course) is passed back to the user. In step 364, the person determines whether the list list is updated. U Has the server 1 received white to perform ΪΓΙΓ judgment Sometimes, the execution steps are as follows, to display the V reverse list update data in the name of the whiteboard " 10, Ruo Niu ... 6 ", that is, %% to know if someone has added a whiteboard. On the contrary, it is determined in 7 steps. Time, jump back to step _. Similarly, after step 365, the person updates the next update time. 丨 Jump back to step 362 to wait for this. With the update whiteboard user in FIG. The design of the early machine is to let all 15 to 2 = the newly added whiteboards, and then to discuss, in order to achieve the effect of the interactive environment of J neodymium. Finally, in conjunction with Figure 5, the process of sharing the method by the server. this example of a whiteboard teaching out first 'In step 41, cut off the county; ^ A 41__ Whether there is a new user login in the ancient neck. If it is judged in the step, go to step 42. Step 43. ^ When the judgement in step 41 is no, skip to 20 photos. In Lesson ^: 42, after Device 1 confirms that the identity of the new user is correct, it passes the whiteboard list sent to the course on ~ to the new user. After step 42 is completed, step 43 is performed. In step 43, the servo cries 丨An instant update of the whiteboard list is required. If there is an early update request received from the client. Sometimes, go to step 44. If not, go to 14 1243347 card 'q ,,,,,, Ding / ping T The teacher selects and sends the requested user to the whiteboard list. Since then, the user has changed the information as the whiteboard list update data and then passed it back to the user ~: After that, skip to step 45. Bega passed on to users. Step 44 ends step 45. In step 45, the sewing machine 1 determines whether a request for “selection = production:” has been received, that is, the user clicks on the whiteboard in the whiteboard list. It is judged that sometimes, if you execute step 46, the temple clothes cry 1 # + pass to the whiteboard data corresponding to the whiteboard selected by ## 10
