Classroom supporting device using projector and working method of classroom supporting device

Abstract

The invention discloses a classroom supporting device using a projector and a working method of the classroom supporting device. The classroom supporting device comprises a blackboard arranged on a wall surface, the projector arranged on a roof, a computer arranged on a table, and a control pen held by a teacher; the blackboard is a flexible board surface which can automatically erase handwritingsand display line grids, and is electrically circularly; a writing board surface and a projection screen are integrally connected with each other so as to form the flexible board surface; the projector is in communication connected with the computer; and the control pen includes a blackboard pen unit, a PPT page turning unit, a laser pointer unit, and a motor remote control unit. According to theclassroom supporting device using the projector and the working method of the classroom supporting device of the invention, multimedia teaching and blackboard teaching are combined perfectly, so thatthe multimedia teaching and the blackboard teaching are integrated naturally and fluently. The classroom supporting device has the advantages of automatic handwriting erasure, line grid display, largecapacity, no chalk dust, wireless PPT page turning, stroboscopic laser guideline and the like.

Description

technical field [0001] The invention belongs to the technical field of teaching appliances, in particular to a classroom matching device using a projector 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 by chalk has l...

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
