What are the hopes of teacher-assisted teaching equipment in multimedia classrooms?

Traditional multimedia classrooms need teaching equipment: computer, projector, projection screen, power amplifier (optional), stereo, microphone (in various forms, such as gooseneck, collar clip, handheld and wireless cable), multimedia control system, multimedia center console, physical exhibition platform, laser page turning pen, etc. This is relatively complete, and the equipment can be appropriately increased or decreased according to the needs and budget.

After the introduction of interactive electronic whiteboard, the combination of computer+projector+projection curtain in multimedia classroom teaching equipment is replaced by computer+projector+electronic whiteboard, which can directly operate the touch screen effect of computer on the board surface of electronic whiteboard, and other equipment is the same.

Interactive LCD TV began to spread, and interactive LCD touch TV replaced the function of computer+projector+electronic whiteboard, with higher integration. The same is true for other equipment.
