The teaching all-in-one machine integrates infrared touch technology, intelligent office teaching software, multimedia network communication technology, high-definition flat panel display technology and other technologies. Finally, I know why so many people choose the teaching all-in-one machine instead of the electronic whiteboard.
Teaching machine
With the widespread use of electronic whiteboards and all-in-one teaching machines in government and enterprise meetings, education and training, many people have raised questions. These two products have similar functions and similar uses. Which one should I choose? Today we will compare the common interactive whiteboard with the more popular teaching all-in-one machine.
operation comparison
The electronic whiteboard system is mainly composed of 6 parts: projector, computer, USB cable, electronic whiteboard, electronic pen (finger) and whiteboard software. The electronic whiteboard is both a display screen and a computer touch screen. It is connected to the computer through a USB cable. The video signal of the computer screen is projected onto the whiteboard through the projector. Through software calculation, the touch position on the whiteboard can be compared with that on the whiteboard. The mouse information of the computer is synchronously corresponding to realize the two-way interactive communication and operation between the whiteboard and the computer. Facing the electronic whiteboard is like facing a larger computer monitor, and the electronic pen (finger) controls the monitor freely like a mouse.
teaching integrated machine is more simple and convenient, a screen can replace projectors, projection screens, electronic whiteboards, computers and other equipment. The conference tablet is like a touch screen computer, with built-in Android system, and Windows system can also be installed. Files can be displayed on the screen by directly plugging in a U disk or connecting the computer with a data cable. It can be operated as a computer with an electronic pen or a finger. machine.
Display effect comparison
The electronic whiteboard has the function of a projection screen, which can be used as a screen for a projector to play computer videos, PPT, images, etc. Compared with ordinary projection screens, electronic whiteboards have low light absorption, high color reproduction, and clearer pictures. However, people standing in front of the projector will still have shadows projected on the screen, which will affect the display effect.
The display function of the teaching all-in-one machine is more "special", not relying on the projector to project light onto the screen, but relying on the light source of the screen itself. Without the "intermediary" of projection, the light will be brighter without drawing the curtains or turning off the lights. , Can also see the screen clearly.
In addition, there are some differences in the resolution of the two products. The projector equipped with the electronic whiteboard generally has a resolution of 1024x768 or 1280X800, while the teaching all-in-one machine has a resolution of 1920X1080. The 84-inch and 98-inch teaching all-in-ones even use a 4K ultra-high-definition screen with a resolution of 3840X2160. In an application environment with the same area, the image quality of the teaching all-in-one is better and the details are more delicate.
touch writing contrast
The writing functions of the electronic whiteboard and the teaching all-in-one machine are very similar. Both can use an electronic pen or finger to write on the screen, and it has both an annotation mode and a special writing page. In the comment mode, you can realize operations such as drawing and circle on the page content; in the special writing page, you can write on the board like a normal whiteboard, and you can also zoom in, zoom out, move, and erase the written content, and change the thickness and adjustment of the pen. Color, and change the background color.
Other function comparison
In addition to the above two functions, electronic whiteboards and conference tablets also have many similar functions, such as one-click screen capture, multimedia playback, remote video and other functions. However, the teaching all-in-one machine has one more "unique" function than the electronic whiteboard-multi-screen interaction.
On the whole, the teaching all-in-one machine integrates the excellent functions of the teaching whiteboard, and is more concise than the teaching whiteboard. This is also the reason why major conference rooms and universities choose the all-in-one machine.
