Teaching and memory tablet integrated machine

Abstract

The invention provides a teaching and memory tablet integrated machine. The integrated machine comprises at least one panel, a controller, a touch device and a handwriting storage device, wherein theplane of the panel forms a projection writing surface of the integrated machine; a reflecting imaging film is arranged on the back of the panel; the controller is used for controlling the data transmission of the integrated machine; the touch device is arranged on the back of the reflecting imaging film, connected with the controller, and used for receiving touch information input to the panel andsending the touch information to the controller; the handwriting storage device is respectively connected with the controller and the touch device, and used for recognizing handwriting information input to the panel through the touch device, storing the handwriting information and sending the handwriting information to the controller. The integrated machine realizes the purpose of projection image reflecting imaging by arranging the reflecting imaging film on the back of the light transmitting panel.

Description

technical field [0001] The invention relates to the technical field of projection teaching, in particular to a teaching and memory tablet all-in-one machine. Background technique [0002] There are many multimedia teaching all-in-one products on the market today. It is a multi-functional interactive teaching device that integrates multiple devices, and upgrades the traditional display terminal to a full-featured human-computer interaction device. Through this product, users can realize multimedia entertainment and computer operation, and can easily perform wonderful interactive classrooms by directly turning on the device to meet the needs of modern teaching applications.

Problems solved by technology

[0003] At present, the projection electronic whiteboard of the multimedia teaching all-in-one machine is a kind of enamel whiteboard or honeycomb board. Its disadvantage is that the image projected on it will reflect and form light spots, which will affect the visual effect of the viewer. Weakened, the viewing angle of the left and right viewing angles is not large enough, and if the viewing angle exceeds 90 degrees, it will be difficult to see clearly due to the problem of reflection

At the same time, the existing enamel whiteboards or honeycomb boards have the following disadvantages. One is that chalk cannot write on the surface and will slip, and the marking pen needs to be wiped with professional potion after writing; Wear and tear will reduce the service life, and at the same time, the picture projected on the enamel surface will be blurred; the third is that the surface is not a flat plate, but an infrared frame or an optical frame is installed on the surface of the whiteboard, and the surface frame has protrusions; the fourth is infrared touch or The optical touch frame is easy to accumulate chalk dust and other dust, and the touch will become insensitive after a period of use

In addition, the surface of the current projection electronic whiteboard cannot directly save the written handwriting content immediately when writing with chalk or pen, and the existing method of saving is to convert the photos taken by the camera into picture format and save them. What is most needed in the course of class is to save the notes written in chalk in the cloud in real time, so that students, parents, and teachers can check them out
