The projector is placed behind the electronic whiteboard, and the projection is only the computer image displayed from the back of the whiteboard, so that the user can operate very naturally and will not block the projection light and produce any shadow. The system composition of the rear projection electronic whiteboard is the same as that of the front projection. It integrates the projector and reserves the placement space of the PC. Because there is little contact at ordinary times, many people don't know much about the use of the electronic whiteboard of the teaching all-in-one machine, but it doesn't matter. Next, I'll explain the relevant knowledge of the tutorial on the use of the electronic whiteboard. If you have this demand, you might as well come in and understand it together!
1. Switching skills between modes
In window mode, when running other applications, the software will automatically switch to control mode. In control mode, click the brush and other tools that can only be used in window mode and annotation mode, and the software will automatically switch to annotation mode.
2. Create, open, and save documents
When you use the interactive whiteboard before class, you can create your own document. As for why you want to create a new one, for example, when a teacher in front of you has used this electronic whiteboard and has not saved the class record, you will enter the window mode and see the class content of the previous teacher, especially when you accidentally click "previous page", you will feel confused, because you don't have the impression that you have written those contents, If you re-enter the whiteboard from the computer desktop, a new document will be automatically created for you, and the above problems will not be encountered.
When you finish a class with an interactive whiteboard and want to review the current class content in future teaching, you can save the class content. The method is that when you exit the software, a selection box will pop up and ask you whether to save it. When you choose "yes", you can take a name and save it in the specified location. When you choose "no" or "Cancel", your class content will not be saved.
When you want to use the interactive whiteboard for a class, and the relevant contents have been used and saved before, you can open the previous class records and start the teaching of this class instead of writing it again. This is also where the interactive electronic whiteboard is superior to the old "Trinity" teaching mode of traditional blackboard, chalk and eraser. We should promote the use of it.
3. Set page background color
In the three modes, selecting new page will create an empty page. By default, the of this new page is pure white. If we want to change a color as the background, we should select "draw" in the main menu, and then select "background color". At this time, the program pops up the background color selection box, and click to select the required page color.
4. Export page as picture
Export some or all pages as pictures, support * bmp、*. jpg、*. Png has three formats. Click "file" on the main menu and select "export as picture". The program pops up the "export as picture" window to select the export range. After selecting the range, the program pops up the second form of "export as picture". Enter the file name, select the save type, and click "save". Exporting a page as a web page is similar to exporting a page as a picture. Click "file" on the main menu, and then click "export as web page". Export some or all pages as web pages. Web pages support * Htm format.
5. The uniqueness of highlighter
Enter the brush selection through the main menu, and there will be some brushes: ordinary brush, fluorescent pen, brush and row brush. In addition to the highlighter, you can choose the other three according to your preferences, and then set the color, thickness and other properties. The highlighter is different from the previous three. It is a translucent pen, which is generally used to annotate the key points. Note that it will not completely cover what you painted. In fact, other pens can also have the same function as a highlighter by setting. This requires setting transparency in the brush custom attribute. It is completely opaque by default.
6. Understand the limitations of the eraser function
Beginners always think that using the eraser can erase the content they get on the whiteboard. In fact, the function of the eraser has many limitations.
First: it can only erase the contents written and painted by ordinary pens, highlighter pens, brush brushes and brush arranging tools, and there must be a premise for this, that is, you can't combine the contents you write and try to erase them.
Second: handwriting recognition cannot be erased. Remember that you can select the text written by handwriting recognition, then click the small triangle in the upper right corner of the selection box, and select Delete in the pop-up menu (this method is very useful).
Third: the graphics drawn by geometric tools cannot be erased by a board eraser, let alone an edge or an arc. Fourth: the contents of the combination cannot be erased with a board eraser.
7. The selection tool is like a mouse pointer. This tool is often used
When you want to delete things that can't be erased with the board, you can use this tool to select objects. When an object is selected, a blue focus frame and edit points will appear on the periphery of the object. About what is an object? You may not understand that in fact, the words you write, the pictures you draw, the pictures you insert, and the photos you take on the page can all be called objects. Note that there are restrictions on the objects here, that is, only on the new page. You don't try to delete a button outside the page, etc.

Note that there are restrictions on the objects here, that is, only on the new page. You don't try to delete a button outside the page, etc.
2) If you are having a literacy class and ask the students to write, you should pay attention at this time. When you choose the brush tool, ask several students to write, and you have not selected any other tool in the process. A student's handwriting is really poor, but fortunately, it can be adjusted to make the words look good. Here you may have a headache. Because when you want to choose the word that is not written well, other words are also selected, which is completely beyond your expectation. In fact, you have been using that kind of brush just now, and it has not been replaced in the middle. The whiteboard software will take the content written in the use process as an object, rather than the number of objects as many words as you think. The solution is to remember to click the selection tool after you use it once, and then select the tool you just used. At this time, the above situation will not occur. Of course, you can click other tools when switching tools, as long as you remember to change them back immediately.
3) You can scale, delete and clone multiple objects by selecting multiple objects in turn, instead of repeating similar operations on only one object at a time.
8. What is the use of locking
Similarly, take literacy class as an example. If you drag a field lattice from the public library and you don't want to change it in the next operation, you can lock it. The method is to select the object to be locked, click the consultant Edit menu button in the upper right corner, and select "lock" in the pop-up menu. After locking, the focus box of the locked object turns red. Unlock: click the lock button again according to the locking steps to unlock.
9. Opening and closing of object combination
By combining, you can combine multiple objects into a whole, and then operate on this whole, just like operating an object. The combination function is also very common, but for beginners, they don't understand its purpose. Using combination can greatly improve the efficiency of some aspects. Imagine that the car is just a pile of scattered parts before assembly, which can not give full play to the function of the car as a whole. The method of combination is to select multiple objects (if there is only one object, it is not necessary to combine), click the consultant Edit menu button in the upper right corner of a selected object, and select "combination" in the pop-up menu. The method of ungrouping is similar, except select ungroup when selecting.
10. Adjust layer, object stacking function
Two objects will inevitably overlap. What should I do? There is a method in the computer, which is very realistic, that is to layer all objects. Like a stack of exercise books, there will be the top one and the bottom one. The homework book above blocks the one below. In the teaching whiteboard, the objects you add first will be placed at the bottom, and the objects you put later will be placed on the top of the previous object in turn. Is this like handing in an exercise book!
11. Select the curtain from the tool to set
Click "tools" on the main menu, and then select "parameter setting"; The parameter setting window pops up, where you can set various parameters; Select the "screen" selection card, select "Browse", select a picture from the computer, and then "OK".
The above is the introduction of the use method and tutorial of the teaching whiteboard in the teaching all-in-one machine. I hope to help friends who need this! For more information, please continue to pay attention to this site, and more wonderful content will be presented in the future!
