It has to be said that in the past, the multimedia display system composed of traditional projectors and computers has been widely used in school teaching, enterprise meetings or business applications, which has improved the speed and intuition of information transmission. With the progress of science and technology, people continue to pursue new things, and the shortcomings of the projector in the use process gradually emerge. In the process of using the projector, the problem that users cannot interact with the computer system in a more intuitive and clear way is becoming increasingly serious, which can no longer meet the needs of people.
Touch all-in-one machine
The teaching touch all-in-one machine adopts the integrated appearance design of the whole machine, integrating the functions of computers, televisions, audio, electronic whiteboards and other devices, which is simple and convenient to install and does not occupy much space. The previous multimedia projection teaching equipment has too many supporting facilities, troublesome installation, cumbersome wiring, and complex operation. The equipment investment cost is much higher than that of the touch machine.
In all the functional applications of teaching touch all-in-one machine products, there will be a core application software, that is, interactive electronic whiteboard software. Its function application is similar to the traditional blackboard, but it is more functional than the blackboard. The important point is that the application of infrared teaching touch all-in-one machine has solved the problem of chalk dust pollution caused by the use of black and white chalk for teachers and students, and created a dust-free, pollution-free, scientific and technological, green education and learning environment for teachers and students.
With the continuous changes of the times, the way of knowledge dissemination is also changing. The traditional teaching mode can no longer meet the learning needs of students in the new era, and can not improve students' enthusiasm and interest in learning. The application of teaching touch screen all-in-one machine, with multimedia technology and human-computer interaction touch function, presents knowledge to students in a new way more vividly and intuitively, improves their learning integration and stimulates their learning enthusiasm.
Compared with the problem of being greatly affected by light in previous projection teaching, the teaching touch all-in-one machine does not have this problem at all. The LCD screen of the large size touch all-in-one machine has a resolution of 1920 * 1080, clear picture, true color, and can adjust the angle at any time, so that every student in the classroom can clearly see the displayed content, thus attracting students' attention and achieving the goal of improving teaching efficiency.
How can the projector not be eliminated when facing the educational touch machine with so many advantages. It is believed that in the near future, although the application of projectors will certainly exist, educational touch machine will completely replace projectors in school teaching, enterprise conference training and other multimedia fields.
