Educational multimedia touch screen computer

Educational multimedia touch screen computer is a large-scale interactive display device tailored to the teaching environment, usually landing in the form of touch control all-in-one machine or intelligent interactive tablet. It deeply integrates 4K ultra-high definition display, multi touch, built-in computing unit and teaching application. Its core mission is to replace the classic combination of traditional blackboard and projector and act as the central interactive platform of digital classroom.

🖥️  Product features: closely follow the needs of teaching scenarios

The essential difference between teaching scenes and industrial, medical, vehicle and other application environments lies in the three dimensions of multi person collaborative interaction, student vision protection and teaching software ecology. Each design of educational multimedia touch screen computer revolves around these core demands.

Visual health and eye protection

When students look at the screen closely for a long time, eye health is an uncompromising bottom line. The national standard GB 40070-2021 Hygienic Requirements for the Prevention and Control of Myopia in School Articles for Children and Adolescents puts forward strict regulations for educational display equipment in terms of blue light suppression, no stroboscopic and brightness uniformity, and the blue light protection level must reach RG0 (no danger). Mainstream products generally adopt DC dimming scheme to achieve stable output of light source, completely eliminate stroboscopic, and provide paper eye protection mode, which can simulate various texture textures such as sketch paper, rice paper, watercolor paper, and effectively alleviate the visual fatigue caused by long-term gaze. Some products have additionally passed the Rhine T ∨ V low blue light certification, which further endorses eye health.

Multi person synchronous touch collaboration

In classroom teaching, multiple students are often required to work on the stage or cooperate in groups. The educational touch screen widely uses infrared touch technology, and the number of synchronous touch points covers a wide range of 20 to 50 points. In the centralized government procurement, 86 inch models usually require 40 points or more of touch capability. High end models can achieve 50 points of synchronous touch and writing. The writing delay is controlled to within 15ms, the touch response time is as low as 4ms, the minimum identifiable touch object is ≤ 2mm, and the writing feel is close to the paper and pen experience.

Dual system architecture and teaching software ecology

At present, the mainstream education touch screen adopts the dual system architecture of Android+Windows, and the two systems can be switched seamlessly with one key to ensure that the teaching process will not be interrupted due to system switching. The Android side is responsible for the quick start of lightweight tasks such as whiteboard writing and courseware presentation; The Windows terminal carries the heavy calculation of professional teaching software and OPS computer module. The built-in teaching whiteboard software generally covers courseware annotation, mind map, classroom interactive answer, multi screen linkage and other functional modules. Some products also introduce AI voice enhancement algorithm, which can significantly improve voice clarity without increasing the volume, and optimize the hearing experience of large class teaching.

Integrated audio, video and peripheral integration

The modern educational touch screen integrates the camera, microphone and speaker into the body. Typical hardware configurations include: 13 million to 19 million pixel cameras, which support 4K image output and serve remote course tours and regular recording and broadcasting; 4-8 array microphones, with an effective pickup distance of 12 meters, can easily cover the sound field of the whole classroom; 2.2 Channel speakers, with the total rated power generally reaching 60W, meet the sound reinforcement and coverage requirements of standard classrooms.

Structural safety and durable design

In the classroom environment, equipment frequently contacts teachers and students, so safety is very important. The shell of the whole machine is made of all metal materials, and the corners are treated with arc fillets, without sharp edges or bulges on the surface, which fully guarantees the personal safety of teachers and students. The screen is covered with fully physically toughened glass, with a surface hardness of Mohs 7 or 9H. The full fit/zero fit process is used to eliminate the air layer between the glass and the LCD panel, and simultaneously improve the touch accuracy and image transparency.

🏫  Typical application scenarios

K 12 Regular Classroom in Primary and Secondary Schools

This is the core landing plate of the educational touch screen. In the standard classroom, teachers can play courseware, handwritten blackboard writing and access multimedia teaching resources through the touch screen, and students can conduct touch operation and interactive answer on the stage. The built-in shortcut menu and floating toolbar of the device support teaching aids such as annotation, screenshot, timing and so on under any signal source. Common teaching shortcut keys can also be customized on the left and right sides. Some schemes adopt the combined layout of main screen and auxiliary screen - the main screen undertakes multimedia display, and the auxiliary screen retains the traditional chalk/whiteboard writing function, which is especially suitable for small class teaching.

College Smart Classroom and Discussion Teaching

College scenes have a stronger demand for multi window parallel and group discussion. Large classrooms can be configured with dual projection or dual screen solutions, medium-sized classrooms can add auxiliary displays, and small classrooms can use intelligent interactive all-in-one machines with side screens. The equipment supports four split screen whiteboard mode, and teachers can open four teaching windows at the same time to present courseware, literature, video, and blackboard writing in parallel, so as to realize the teaching of multiple topics in comparison; The global zoom function supports one click zoom and layer by layer analysis of complex charts. In the seminar type classroom, the touch screen supports multi-channel wireless projection, which can accommodate up to 9 terminal devices simultaneously and automatically complete the split screen layout.

Preschool education enlightenment and interest interaction

Kindergarten scenes have unique requirements for the number of touch points and interactive interest. The all-in-one preschool education machine generally uses a 65 to 86 inch screen and supports more than 40 touch points, which is convenient for multiple children to operate and write at the same time. Some products integrate AI voice control module, and teachers can quickly start whiteboard software, screen transmission interactive tools or preschool education applications through voice commands, greatly reducing the operating threshold.

Video Classroom and Distance Interactive Teaching

The educational touch screen equipped with high-definition camera and array microphone can support multiple modes such as regular recording and broadcasting, remote class tour, online and offline hybrid teaching. Recording and broadcasting support screen images, screen+camera picture in picture and other recording forms. Sharing can be opened at any time during the recording process. The listening end can scan the QR code to enter the live classroom and participate in interaction. The device is compatible with HTML5, RTSP, RTMP, WebRTC and other mainstream protocols, and can achieve seamless connection and synchronous interaction with the existing smart classroom platform of the school.
