(I) Educational Field
Interactive flat panels play a core role in educational scenarios. Teachers can utilize their rich teaching software to display multimedia courseware, videos, 3D models, and other teaching contents, making abstract knowledge more concrete. For example, when explaining the structure of cells, showing 3D dynamic models can help students understand better. In class, students can participate in interactive quiz activities and display the results of group discussions through touch operations, enhancing their learning enthusiasm and sense of participation. Meanwhile, its annotation and writing functions can replace traditional blackboards, facilitating teachers to mark key points and write blackboard writing in real - time. Additionally, teaching contents can be saved as electronic documents, which is convenient for students to review after class.
(II) Business Office
When used in business meetings, interactive flat panels can display PPTs, data reports, and other materials through wireless screen projection. They support multiple people annotating and modifying simultaneously, improving the efficiency of discussions. In the scenario of remote meetings, high - definition cameras and microphones, combined with video conferencing software, enable smooth communication and collaboration across different locations. In corporate training, instructors can use their rich media resource display functions to conduct case analyses and skill demonstrations, making the training content more vivid and intuitive.
(III) Public Display and Information Inquiry
In public places such as shopping malls, exhibition halls, and airports, interactive flat panels serve as information inquiry terminals. Users can obtain store navigation, exhibit introductions, flight information, and other contents through touch operations. They can also be used to display advertisements and promotional videos for activities. By means of interactive mini - games, questionnaires, and other forms, user participation can be attracted, enhancing the effectiveness of information dissemination.
(IV) Home Entertainment and Learning
At home, interactive flat panels can be used as large - screen intelligent terminals for watching high - definition movies and TV shows and playing somatosensory games, providing an immersive entertainment experience. At the same time, they can also be used as learning tools for children. By running various educational APPs, functions such as online course learning and homework tutoring can be realized.
