Interactive demonstration system

Abstract

The invention discloses an interactive demonstration system. The system is technically characterized by comprising a slidable bottom frame; an electronic white board is arranged above the bottom frame; support rods are arranged at both sides of the electronic white board respectively and are fixedly connected with the bottom frame; a height-adjustable projection rod is arranged on each support rod; and a projector capable of projecting onto the electronic white board and a projector assembling seat for mounting the projector are arranged on the projection rods. The system has the advantages that the projector is integrated with the electronic white board creatively; an explainer can stand outside the projector and uses a thin rod to point to the electronic white board for explanation due to the facts that the projector is near to the white board and can move horizontally and the angle of the projector is adjustable; and thus, a better teaching effect is obtained due to no barrier exists in the projection path.

Description

【Technical field】 [0001] The invention relates to a portable audio, video conference and presentation system. 【Background technique】 [0002] In teaching or large-scale meetings, explainers often need to use a projector to project pre-prepared materials, slides, etc. on the electronic whiteboard for participants to watch, but traditional projectors and electronic whiteboards are completely separated. Part, when it is necessary to adjust the mutual position between the two, it is necessary to adjust the two separately, which is very troublesome, time-consuming and labor-intensive, and because the distance between the traditional projector and the electronic whiteboard is relatively long, once the projector There are obstacles or people on the projection path of the electronic whiteboard, which will block the image on the electronic whiteboard, thereby improving the effect of image teaching or explanation. Moreover, the real-time interaction ability of the traditional projecto...

[0002] In teaching or large-scale meetings, explainers often need to use a projector to project pre-prepared materials, slides, etc. on the electronic whiteboard for participants to watch, but traditional projectors and electronic whiteboards are completely separated. Part, when it is necessary to adjust the mutual position between the two, it is necessary to adjust the two separately, which is very troublesome, time-consuming and labor-intensive, and because the distance between the traditional projector and the electronic whiteboard is relatively long, once the projector There are obstacles or people on the projection path of the electronic whiteboard, which will block the image on the electronic whiteboard, thereby improving the effect of image teaching or explanation. Moreover, the real-time interaction ability of the traditional projector system is poor. When the explainer needs to mark or even modify the slide When using a computer, only a computer can be used for operation, which is poor in operability, time-consuming and labor-intensive

In addition, the position of the existing projector is generally fixed, and the angle is not adjustable, so that the projection range is limited
