Display system for aided teaching

Abstract

The invention discloses a display system for aided teaching and relates to the field of display technical equipment. The system comprises a data processor and an image acquisition device. The data processor is provided with a software control module, an image processing module, a switching module, an integration module and a preservation and display module. The image acquisition device comprises a camera. The display system can be used for displaying not only powerpoint but also handwritten information, real objects and the like; meanwhile, the powerpoint can be annotated and marked independent of traditional black / white boards, namely, the function of an electronic white board can be achieved; image magnification, enhancement, cutting and other types of processing are conducted on displayed content through the image processing module and then the content is transmitted to display equipment such as a projector to be displayed, so that the problem that sight lines of audience are blocked when a user writes on white / black boards or audience cannot see clearly when writing fonts / printed fonts / real objects are too small is solved. In addition, content photographed by the camera can be superimposed onto and preserved in current powerpoint, thereby being conveniently and repeatedly used later.

Description

technical field [0001] The invention relates to a multimedia display system, in particular to a display system for assisting teaching. The system can be used in conjunction with other demonstration software, especially office automation software, which is a tool for assisting a demonstrator to perform a demonstration. Background technique [0002] Office automation software is a tool for information processing and an important means for people to generate higher value information. It includes the integrated processing functions of text, data, language, image and other information. Commonly used office software includes Microsoft Office developed by Microsoft Corporation, Smartsuite developed by Lotus Corporation, and WPS developed by Zhuhai Jinshan Software Co., Ltd. of my country. Among them, the most widely used in the world, especially in China, is Microsoft Office developed by Microsoft Corporation, which integrates the functions of Word, Excel, Power-point, Access, Out...

Problems solved by technology

[0005] (1) The "digital / video booth" simply integrates the functions of displaying videos, real objects, and displaying handwritten materials. It does not further process the displayed content, such as correcting, cutting, and removing the displayed content background, save

At the same time, the digital / video booth cannot insert the content captured by the camera into the existing presentation document and save it, so that the presentation document cannot be annotated and marked, and the function of "electronic whiteboard" cannot be realized

In addition, the digital / video booth systems proposed at this stage are relatively expensive. For users who already have equipment such as computers and projectors, the cost of purchasing an additional digital / video booth is too high

At the same time, if the familiar office automation software such as Power-point can partially make up for its shortcomings or realize the required functions on the basis of existing computers and projectors, it will have a multiplier effect. It is not necessary to use another software / device (digital / video booth), because it takes a process and a lot of effort for a person to learn or get used to using another software / device

[0006] (2) Neither the "electronic whiteboard" nor the "Manuscript King" digital notebook can display handwritten materials written on paper, nor can it display printed materials and real objects; when entering text, formulas or graphics, special writing tools are required— —The electronic whiteboard needs to use Hanwang pen or laser pointer, etc., and the "Manuscript King" digital notebook needs to use a special digital ballpoint pen, and these special writing tools used are generally more expensive; settings (such as text color), once the writing is done, it cannot be modified, and at the same time, if the writing content is skewed (not horizontal) or we are only interested in part of the content, the electronic whiteboard cannot correct it to level, nor can it Cut it to get the content of the area of ​​interest. In addition, the electronic whiteboard cannot transparently superimpose the written content or inserted image content on the background for display, causing the problem that the written content or inserted image covers the background content.
