Wall surface integrated interactive electronic white board

Abstract

The invention provides a wall surface integrated interactive electronic white board, and belongs to the technical field of electronic information. The white board consists of a writing operation screen 1 and a large screen display panel 2, wherein the writing operation screen is positioned on one side of the large screen display panel and consists of a touch screen, a controller, a display, a large display screen or a projector, a projection curtain, a computer and a screen divider. When writing or operating in a near distance, a user uses the higher-resolution writing operation screen relevantly smaller than or as large as the large display panel, and students can watch the large display screen or a projection in a far distance, so the problem of height restraint of the user when writing operation is performed on an overlarge screen and the problem that the user who writes on a large screen in the near distance feels dazzling light and stops the sight line of the students and projection light are solved. The electronic white board combined with software realizes writing on a computer screen, and computer operation and word type-in are performed without a key and a mouse through a pen, so the right key function of the mouse is enhanced, and the left key and the right key of the mouse can be switched easily and quickly.

Description

technical field [0001] The invention relates to a wall-integrated interactive electronic whiteboard that conforms to the habit of writing on the wall, can not only write, but also can conveniently operate a computer, demonstrate courseware, and display synchronously or asynchronously with a large screen. Background technique [0002] As an emerging interactive presentation system in recent years, the interactive electronic whiteboard can write on the electronic whiteboard very conveniently, save the content to the computer, mark the content of the computer screen, and operate and control the computer. However, general interactive electronic whiteboards cooperate with projectors to complete teaching. The operation panel is also used as a projection screen. It is bound to exist that the human body blocks the projected light when writing or operating the computer, and the human body will be subjected to the strong light irradiation problem of the projector simultaneously. At ...

AI Technical Summary

Problems solved by technology

On the one hand, the user’s eyes will feel uncomfortable due to blurred vision when writing at close range on the large screen of the electronic whiteboard.

In addition, due to the limitation of the user's height, the large-screen electronic whiteboard cannot effectively combine the large-screen display and writing operation when used in a large classroom, which brings great inconvenience to operation and writing

Some writing boards or writing screens integrated into the media podium generally do not have a complete right mouse button function that can be quickly switched, which greatly affects the continuity of writing and computer operations, and does not conform to the wall panel writing habits

Although the newer and improved electronic whiteboard solves the problem of the large-screen electronic whiteboard being limited by the user's height, because the display system uses the same projection screen, there are still problems in which the human body blocks the projection light when in use, causing glare, and the eyes are resistant to short-distance operations. The degree of acceptance is low, the size of the operation tablet and the display screen are not uniform, the operation is difficult, and the problem of natural writing cannot be realized

Compared with the writing screen, the main problem of the writing board is that it does not have a display function. When writing or operating, you need to look at the large screen, and it is not easy to quickly and accurately click on the position.
