"Black technology" of intelligent interactive blackboard
The essence of information technology is to serve education and teaching. With the popularization and application of information technology, the problems in education and teaching have been well alleviated. In order to meet the needs of students and teachers, great changes have taken place in teaching equipment and educational methods.
The 2 action plan of education informatization clearly points out that we should continue to promote the deep integration of information technology and education and build an integrated platform for "Internet plus education" to speed up the modernization of education and the construction of powerful nation in education. With the promotion of educational informatization 2.0 policy, the teaching needs of schools are constantly upgrading. Blackboard is a necessity of education and teaching. Starting from the traditional blackboard, through the iteration of electronic whiteboard and touch all-in-one machine, the intelligent interactive blackboard with the functions of traditional chalk writing and touch screen interactive teaching has become an important trend in the future.
However, in terms of teachers, various information equipment can not be interconnected and the operation is complex, which will greatly increase the difficulty of teachers and increase the idle rate of equipment. In terms of students, not only does "light pollution" affect students' vision, but also students can't accept the content delivered by teachers in time and effectively in class.
How to solve these problems of teachers and students? The emergence of intelligent interactive blackboard not only effectively solves the above problems, but also brings a new teaching experience, making it easy for teachers to teach and students to learn.
Intelligent interactive blackboard adopts infrared / capacitive touch technology, which integrates traditional blackboard, large screen display, touch interaction, OPS computer, audio, Internet of things and other related equipment, and gives full play to its technical advantages. It fully meets the operation requirements of teachers for high-frequency switching of various equipment. All functions commonly used by teachers can be achieved with one key, which is convenient to use and fully conforms to their own teaching habits. Equipped with intelligent and convenient hardware structure and powerful and accurate software application, it can change the traditional teaching methods, improve classroom teaching efficiency and reduce teachers' teaching burden.
The blackboard adopts comprehensive fitting technology, millisecond response speed, sharp pressure sensing, high touch accuracy, bid farewell to the sense of suspension and experience more smoothly. At the same time, the whole blackboard has the functions of multimedia teaching and chalk writing. The distance between chalk and LCD screen is 0mm, and the touch of writing is exactly the same as that of blackboard. The integrated flat panel design improves the brightness and contrast, and the viewing angle reaches 178, showing a wider viewing angle, higher light transmittance and higher image quality. In addition, it also has ultra-high strength and ultra-high wear resistance, so as to realize impact resistance and splash resistance, and effectively ensure the use safety.
In order to meet teachers' traditional writing habits, the blackboard supports a variety of writing methods, such as chalk, water pen, etc. It is very convenient for the teacher to write and draw on the blackboard. Each stroke is free, without frustration, and has high sensitivity, just like writing on paper.
Aiming at the problem of "light pollution" mentioned above, the blackboard starts from two aspects: color gamut and eye protection. First, the color gamut is increased to 90%, making the picture color more vivid, rich, delicate and beautiful; 4K high-quality display screen fully displays the picture details, and teachers and students have a more comfortable viewing experience. At the same time, in order to protect the eyesight of teachers and students, 90% of the short wave blue light is effectively filtered by adjusting the LED chip on the blackboard screen to protect the eyesight of teachers and students from the source. The presentation of intelligent interactive blackboard has changed the current situation that rigid blackboard writing and projection can only present one-way and lack of communication, made classroom teaching more vivid, formed an interactive and cooperative teaching environment, and realized the perfect combination of information technology and classroom teaching.
