Abstract

The invention discloses classroom supporting equipment with a projector and a computer and an operating method thereof. The classroom supporting equipment comprises a chalkboard arranged on a wall, the projector arranged on a roof, the computer arranged on a teacher's desk, and a control stylus for a teacher to hold in the hand; the chalkboard is a flexible panel that may automatically erase writings, may display la grid and may provide electric circulation; the flexible panel is integrally formed of a writing panel and a projection screen; the projector is in communicated connection with thecomputer; the control stylus includes a chalkboard stylus unit, a PPT page-turning unit, a laser pointer unit, and a motor remote control unit. Multimedia teaching is perfectly combined to chalkboardteaching, so that the multimedia teaching and chalkboard teaching are naturally and smoothly combined in a whole.

Description

technical field [0001] The invention belongs to the technical field of teaching equipment, in particular to a classroom matching device using a projector and a computer and a working method thereof. Background technique [0002] With the development and popularization of computer technology, multimedia technology with computer video and audio as the medium is widely used in classroom teaching. However, the traditional teaching method with blackboard and chalk as the medium is still the mainstream of classroom teaching. Multimedia teaching and traditional teaching have their own advantages and disadvantages. We should effectively integrate multimedia technology into traditional teaching, so that multimedia teaching and traditional teaching can be integrated naturally and smoothly. But there are many problems in the classroom supporting devices: ①The traditional blackboard, chalk and multimedia teaching equipment are independent and controlled separately. ②The dust produced ...

AI Technical Summary

Problems solved by technology

However, there are many problems in the classroom supporting devices: ①The traditional blackboard, chalk and multimedia teaching equipment are independent and controlled separately, and the operation process is troublesome.

②The dust produced by chalk has long troubled the physical and mental health of teachers and students

③Wiping the blackboard with an eraser is laborious and unclean

④The capacity of the current blackboard is small, which cannot meet the needs of teaching with more content

⑤The current blackboard cannot automatically display various lines and grids, and cannot meet the needs of different disciplines for lines and grids

⑥In multimedia teaching, in order to control the page turning of PPT, teachers often can only move within a small distance from the computer, and the interaction with students is limited

⑦ It is inconvenient to use the traditional pointer for guidance in multimedia teaching. The existing laser pointer is not easy to attract students' attention, and the guidance effect is poor

[0003] In addition, existing whiteboard markers cannot replace blackboard markers, because blackboards are different from whiteboards. If you want to write clear words on the blackboard with writing liquid, the writing liquid must have a higher concentration to completely cover black. The pressure cannot leak higher concentration writing fluid
