And infrared electronic whiteboard is arranged in middle of touch area

Abstract

The invention discloses an infrared electronic whiteboard with a centered touch area. The infrared electronic whiteboard comprises an electronic whiteboard panel, a whiteboard host, an infrared touchmodule, a projector and a video camera. The frame is arranged in the circumferential direction of the electronic whiteboard panel. The whiteboard host, the infrared touch module, the projector and thevideo camera are electrically connected with the whiteboard host. The electronic whiteboard panel comprises a left hand writing area, a touch area and a right hand writing area which are sequentiallyarranged from left to right, and the touch area is arranged in the middle of the electronic whiteboard panel. A first baffle is arranged between a touch area and a left hand writing area, and a second baffle is arranged between the touch area and a right hand writing area. A first optical reflection strip is arranged along the surface of the side, away from the left writing area, of the first baffle, and a second optical reflection strip is arranged along the surface of the side, away from the right writing area, of the second baffle. By means of the electronic whiteboard, it can be guaranteed that viewers located at all positions in front of the electronic whiteboard can see display images of the touch area clearly.

Description

technical field [0001] The invention relates to an electronic whiteboard, in particular to an infrared electronic whiteboard with a centered touch area. Background technique [0002] Infrared touch electronic whiteboard has the advantages of fast response, high precision, long life, and is not affected by touch force, current, and voltage interference, so it is widely used in conference rooms, classrooms, exhibition halls, etc. [0003] With the continuous development of large-scale products, due to the limitation of the projection range and the energy and optical angle of the infrared touch module of the electronic whiteboard, it is often subject to structural constraints in K12 education and other application fields. A common practice in the market is to assemble a green board around the electronic whiteboard to facilitate the displayer to write. The electronic whiteboard with this structure is cumbersome in structure and inconvenient to use. It is also possible to projec...

Problems solved by technology

The common practice in the market is to assemble a green board around the electronic whiteboard to facilitate the displayer to write. The structure of the electronic whiteboard with this structure is cumbersome and inconvenient to use.

There are also projects where the touch area is placed on one side of the whiteboard, but the touch area is set on the left side or the right side of the electronic whiteboard. This method will make the students sitting on the other side in front of the electronic whiteboard / Participants cannot see the courseware in the touch area clearly, and the boundary between the writing area and the touch area of ​​the existing whiteboard is not clear, so it is easy to cause interference or misuse of the touch area during writing operations
