Interactive electronic whiteboard system

Abstract

The invention discloses a wirelessly remotely controlled electronic whiteboard system. The system consists of a projector, an interactive electronic whiteboard and a multimedia computer, wherein the interactive electronic whiteboard consists of an input unit and an output unit; the input unit is a wireless remote control mouse for input without a supporting plane; the output unit is a projection whiteboard; and information input from the wireless remote control mouse can be processed through the multimedia computer and projected onto the projection whiteboard through the projector. According to the system, the problem in positioning accuracy and stability of the interactive electronic whiteboard is solved, the limitations of an input range and the height of a teacher are eliminated, the area limitation of the interactive electronic whiteboard is eased, the teacher can perform handwriting directly on the interactive electronic whiteboard, and the productiveness of a conventional means is effectively combined with the presupposition of a modern means.

Description

technical field [0001] The invention relates to an interactive electronic whiteboard system, in particular to an interactive electronic whiteboard system with wireless remote control. Background technique [0002] As we all know, interactive electronic whiteboards are developed by adding input functions to projection screens, and are the integration of input devices and output devices. Because it liberates teachers from the shackles of computer input, teachers can return to the podium to teach students, making great contributions to promoting classroom modernization. However, the existing interactive electronic whiteboard still has the following problems: (1) Inaccurate positioning and difficult input. The projection surface of the projector is highly coincident with the input plane of the interactive electronic whiteboard, which is the main guarantee for accurate positioning. However, the projector is poorly fixed, and it is easy to move its position during maintenance an...

AI Technical Summary

Problems solved by technology

However, the existing interactive electronic whiteboard still has the following problems: (1) inaccurate positioning and difficult input

However, the projector is poorly fixed, and it is easy to move its position during maintenance and other operations, and the projection surface is even deformed, resulting in inaccurate positioning

Moreover, the input unit of the interactive electronic whiteboard is exposed to the interference environment of the classroom, and the input stability is poor

Many teachers give up inputting from the interactive electronic whiteboard, and the interactive electronic whiteboard has been reduced to an early curtain, and its interactive advantages cannot be brought into play

(2) The input range is limited in front of the interactive electronic whiteboard

On top of interactive whiteboards, teachers are often unable to type, especially a challenge for female teachers who are not tall enough

(4) It is difficult to expand the interactive electronic whiteboard

The screen area is too small, which limits the input area reserved for courseware, puts forward higher requirements for students' eyesight, and students' sight is more likely to be blocked by teachers

(5) The advantages of traditional blackboard writing are lost

They have a common disadvantage, that is, the screen is too small, and teachers are bound by the small screen, which reduces the chance of direct interaction with students

[0006] In particular, the calculation process of the interactive electronic whiteboard is simplified, and there is still no improvement in the perspective of the device
