Definition of smart whiteboard
The smart whiteboard is a large touch screen composed of a smart board and a projector. A pointer or finger is used instead of a mouse to control the image on the smartboard. You can also use your finger as a pen to draw a circle on the image or make other annotations to make the expression more clear. The operator personally feels very kind.
The purpose of smart whiteboard
The intelligent electronic whiteboard system adopts a brand-new whiteboard technology, the size can be adjusted adaptively in the range of 60-150 inches, and the indicator can be used for handwriting annotations in the projection area. Its innovative breakthrough has brought a new interactive teaching method, which can effectively promote teacher-student interaction, activate the classroom atmosphere, and improve the quality of teaching.
The function of a powerful annotation is well received by teachers.
The text or graphics written on the smartboard can be instantly saved in various formats (JPG, HTML, PDF, etc.) to the computer; the smartboard can automatically recognize the color of handwriting and erase actions; The data stored in the computer can be edited and pasted to other files or applications, and the teaching content, including PPT, Word, Excel documents and various formats of pictures and other teaching courseware can be easily remarked and modified. The speaker is on the screen Operators in the curtain operation harmony sound can be AVI texts and afterward, which can effectively improve the effect of students’ listening to lessons and greatly improve teaching efficiency.
Interactive smart whiteboard
Currently, the most widely used is the interactive smart whiteboard. An interactive smart whiteboard, it is a large touch screen with an electronic writing pad and touch function. It can form the best conference, training, teaching, presentation, and presentation system with a computer and projector. It can also be combined with ISDN, LAN/WAN, and other networks or ordinary telephone lines to form a real-time, interactive, and efficient conference system.
Using the interactive smart whiteboard, you can use the existing network to create a more concentrated learning environment. It can enrich classroom teaching, save time, keep track of students’ learning progress, and always focus students’ attention on classroom learning.
The software is powerful, it is a set of excellent classroom teaching, computer experiment, and computer control software. From a single point, the teacher can monitor, guide, and control the student’s computer, and send the software demonstration to any student’s computer.
Whether on different floors or distributed around the world, participants can instantly share text, graphics, and various Windows software, and the effect is as if they were meeting in the same meeting room. Through multipoint solutions, through ISDN\LAN\WAN, multipoint network conferences or remote teaching can be held to realize resource sharing.
The combination of smart board and video conferencing software forms a perfect video conferencing solution with data, image, sound, and other technologies, providing a new realm for your communication. The video conference can transmit lifelike images of the participants in the two places, and the two parties can also have a cordial conversation. Through the smartboard, people can exchange various opinions and suggestions clearly and accurately.
Various comments made on the board can be transmitted to each other in real-time, and both parties can conduct real-time, interactive, and comprehensive discussions on the smartboard so that your various problems can be solved.
Classification of interactive smart whiteboards
According to the installation type of the electronic whiteboard, the electronic whiteboard can be divided into wall-mounted, slide-type, mobile, and closet-type.
According to the positioning principle of the electronic whiteboard, electronic whiteboards can be divided into five types: electromagnetic induction, infrared, ultrasonic, resistive pressure, and CCD.
According to the installation position of the projector, the electronic whiteboard can be divided into front projection electronic whiteboard and rear projection electronic whiteboard.
Front projection electronic whiteboard
The projector of the front-projection electronic whiteboard is placed on a mobile cart or installed on the ceiling to project the image on the computer onto the whiteboard. The projector of the rear projection system is enclosed on the back of the whiteboard with a cover. Compared with the front projection type, the rear projection type is generally more expensive and less used in schools.
The front-projection electronic whiteboard is the projector placed in front of the smartboard, and there is a wall hanging on the back of the board and a pair of brackets, which can be hung on the bracket or the wall.
The front-projection interactive whiteboard installed on the wall and the projector installed on the ceiling can save space on the ground, because the whiteboard bracket is no longer needed, and there is no need to place the projector with a mobile cart in front of the classroom.
Installing the projector on the ceiling eliminates the risk of people tripping over the wires. It can also reduce shadows on the whiteboard and ensure that the projector is always positioned correctly.
Rear-projection electronic whiteboard
The rear-projection smart board has clearer images than other whiteboards and is not affected by external light sources, and can be built-in all computers, multimedia, and communication equipment.
Rear-projection electronic whiteboard is a projector placed behind the electronic whiteboard to project only the computer image is displayed from the back of the whiteboard so that the user can operate very naturally without blocking the projection light and causing any shadows.
The system composition of the rear-projection electronic whiteboard is the same as that of the front-projection. It integrates the projector and reserves space for the PC.
Rear-projection whiteboards are divided into cabinet-type electronic whiteboards and wall-mounted electronic whiteboards according to installation.
Wall-mounted electronic whiteboard
The wall-mounted type requires a dark room to place the projector, and the rear projection screen is embedded in the wall. The wall-mounted type can save space to the greatest extent and create an open and professional working environment.
The smartboard is inlaid on the wall, and the projector is placed in the darkroom inside the wall to project from behind. The speaker can stand directly in front of the whiteboard without blocking the light. The rear projection is embedded in the wall and the push-pull movable blackboard is external, Integrated design, application, and storage are very convenient, this program is suitable for new schools.
Cabinet type electronic whiteboard
The cabinet type can move the entire equipment from one room to another, or place it firmly in a certain position by adjusting the cabinet casters.
The multifunctional smart board is mounted on a cabinet rack, and the projector is placed in the rack to project from the back. The speaker can stand directly in front of the whiteboard without blocking the light. Computers and VCDs can also be placed in the rack, the overall structure is compact and simple.
After the first installation is complete, it can be pushed around without reinstalling.
The rear-projection interactive whiteboard installs the computer and the projector in one device and keeps the equipment in the same place, which can also save space. It can also minimize wiring and eliminate the need for repositioning.
The rear-projection interactive whiteboard (digital blackboard) makes the classroom teaching process more fluent, and the interactive whiteboard (digital blackboard) makes a significant change in the teaching structure.
