7. Specific function introduction

powerful writing function

(1) The blackboard interactive device adopts the most advanced infrared plus ultrasonic technology. It is composed of an electronic pen and a blackboard interactive receiver. The optical signal sent by the pen is received and recognized by the board interactive device. After the optical signal is converted into a mathematical signal and then The projector connected to the computer is finally projected on the projection blackboard, so it relies on light to propagate signals, so its writing response speed is the fastest among similar products, and we use 9-point lock positioning so its accuracy The stability and stability are also very high.

(2) The electronic pen has two functions:

First, when switching computer desktops, the electronic pen is equivalent to a wireless mouse, the tip of the pen is equivalent to the left button, and the round button is equivalent to the right button. When the pen tip double-clicks a tool or folder on the computer desktop, it can be operated like a mouse.

Second, when switching to the electronic board, the electronic pen can perform writing operations.

(3) The traditional chalk blackboard writing teaching is the basic standard required by the international teaching syllabus, while ordinary electronic boards can only support a single handwritten electronic pen input, and our blackboard writing interactor can make multimedia electronic pen input and traditional blackboard writing teaching compatible. Combined, it solves the long-standing major problem that the electronic whiteboard can only input electronic fonts but cannot write on the blackboard.

(4) Our electronic pen handwriting input is also innovated on the original basis. We can not only perform ordinary handwriting input, but also edit handwritten characters directly on the board to print, which is more convenient for teaching. Moreover, the color of the font and the thickness of the line can be adjusted according to the needs of classroom teaching, and there are also artistic fonts to choose from to help make blackboard newspapers and titles.

Portable drawing function:

(1) In order to better cooperate with the teacher's classroom teaching and improve the teaching efficiency, it is also equipped with the function of only the brush, which is very easy to operate: just click the function of the smart brush on the toolbar, and then use the electronic pen to draw on the board. Draw the graphics you need on the surface, such as circles, triangles, quadrilaterals, pentagons, and stars. After hand-painting, you can immediately restore it to a standard graphic that can be drawn like a compass, set square, and ruler.

(2) A simpler and more convenient way to assist in drawing is to directly click on the shape tool to select the desired shapes, such as circles and squares, which are commonly used in classrooms. Graphics, and then drag the mouse to control its size, drag to the size you need to remove the pen tip from the board.

Various deletion methods

(1) There are many ways to delete writing marks after writing. The basic deletion method is the eraser function on the toolbar. Just click it, move the pen tip to the line or text to be erased and drag the pen tip to clear it. .

(2) Press and hold the round button on the top of the pen to display the eraser function. The specific wiping process is to drag the pen tip to the area or text to be wiped and then drag it to clear it.

(3) Select the "smart pen" to draw a cross on the selected content to be deleted, and the selected content can also be deleted.

(4) When there are many screen contents, we can also choose the function of clearing the screen. After clicking "Clear Screen", you will be prompted whether to delete all the contents on the current screen. After clicking "OK", all the contents on the current screen can be deleted.

Expandable writing area:

(1) When there is no space left to write on the board and there is content to be preserved, we can use the board roaming function, click and drag the "roaming" function to drag the written board to the top, so that there will be A new blank area can continue writing teaching. If you want to find the previously written content, you can directly use the zoom-in function of the navigation to retrieve it.

(2) A new page can be created for writing teaching. The board has a page-turning function. Just click the page-turning button to retrieve the previously written content.

Perfect courseware assisted teaching:

(1) Different from other electronic whiteboards that can only play the courseware in the computer, our blackboard interactive device saves a large number of courseware, such as protractors, rulers, and calculators used in math classes. There is an electronic version and intelligent reading, which is faster and more convenient to use. Geography, music, physical education, etc. are also equipped with maps, staves, court tactical boards, etc., which can improve the efficiency of the classroom. In order to assist classroom teaching and make students more focused, there are also functions such as spotlights, screen capture, and color filling.

(2) It can read the PowerPoint documents used in the existing classroom teaching, and can directly make annotations and modifications on the courseware.

(3) Equipped with the most complete courseware of the central audio-visual library, you can find the corresponding courseware according to the teacher's classroom content, so as to better facilitate teaching, increase the interaction between teachers and students, and activate the classroom atmosphere.

Efficient storage and printing functions: the courseware lecture notes after class can be directly saved, used in future classroom teaching or to facilitate academic discussions among other teachers, and can also be printed out and sent to students, which solves the problem of students being busy taking notes in class The problem of not being able to patent lectures can greatly improve the learning efficiency of students.

8. The concept of energy saving and environmental protection of blackboard interactive device:

The blackboard interactive device adopts the most advanced concept of energy saving and environmental protection. It is small and easy to carry and install. When installing, it only needs to be adsorbed on the metal plate to save time and effort. It only needs a special projection blackboard and a projector. And a computer can realize multimedia teaching operation. The old-fashioned projection screen can only be used for projection and cannot be used for writing on it. Lectures need to be equipped with a blackboard for writing. The blackboard interactive device can solve this series of problems. It only needs a professional matt enamel projection blackboard. With projection and chalk writing functions, the blackboard interactive device can also be used for writing with electronic pens, realizing multiple functions on one board and making full use of resources. Since the blackboard interactive device adopts the working principle of infrared rays and ultrasonic waves, it is transmitted by light, so even if the board surface is damaged, it will not affect its normal use, and the special matt enamel board surface is corrosion-resistant, durable, not easy to damage, and has a long shelf life. Up to 30 years. The common electronic whiteboards on the market now use electromagnetic or pressure-sensitive technology to receive signals through contact with resistance wires or electromagnetic wires under the board surface. If the surface of the whiteboard is damaged or the humidity in the classroom is too high, it will affect its sensitivity and normal operation. In addition, the surface of the ordinary whiteboard has not been treated with glare, and it will easily cause eye fatigue when viewed for a long time. The surface of the professional matt enamel is treated with anti-glare. The reflected light is more soft and non-glare, and it can be used in classroom teaching to fully protect students' eyesight.

Therefore, the blackboard interactive device truly achieves the modern scientific and technological concepts of resource saving, durability, convenient installation, best use of everything, safety and environmental protection.
