Description

Development of MultiLecture Operating System {Portable MultiLecture Operating System}

The present invention provides a state-of-the-art lecture / storage / playback system by combining a computer main body and a monitor, and functionally store lecture contents, that is, lecturer / student screen, lecturer / student voice, VGA screen, and all applications on a window. Equipped with an INPUT card that can receive / output, it can be used during lectures by connecting all educational materials such as a physical imager, a camera, an LCD Projector, a VTR, and a DVD, and the monitor of the present invention performs the writing and eraser functions which are functions of a traditional blackboard. Of course, it enables the writing board to perform the writing function on every application on the window so that all the students can effectively take the course through the large screen during the lecture. For remote lectures or VOD lectures, a codec is installed in the main body of the system, and a board for storing VGA and audio signals is installed.

The system is designed to be about 50CM × 45CM × 25CM (drawing I) and made of small and light material so that it can be easily carried and used anywhere and anytime. Unlike the all-in-one computer, the monitor of this system is able to adjust the angle freely. When the monitor is placed at an angle of about 15 ° C, the monitor can be thought of as a notebook and can perform writing function, which is very helpful for lectures and briefings. Will be. In order to perform the writing function, it should be operated only by a dedicated pen so that no malfunction occurs even if it is touched by hand or other objects.The palette-shaped tool is displayed on the screen to enable color, pen thickness, It utilizes the invention of a palette-type software that allows you to adjust the eraser size, etc. The function of this palette makes it easier for users to use the Function Key.

Pallet-type writing software has functions of pen, highlighter, color, thickness, partial enlargement , eraser, and writing / mouse function switching. All of these functions can be performed by one touch of dedicated pen.

The purpose of the present invention is to create an educational environment in which students can concentrate completely on the class in an educational environment in which the lecture contents cannot be focused on the lecture contents while recording or dictating the lecture contents, and the instructor provides cutting-edge multimedia materials suitable for the times. The aim is to make the development of high-tech multimedia textbooks very easy by making it very easy to make an advanced educational environment and to create national profits as well as corporate profits.

The developed contents can be copyrighted to the creator and protect the rights, and the textbooks can be linked to the educational project, and the level of the textbook can be continuously upgraded and the system can be continuously improved.

The present invention is a pallet-shaped writing and electronic technology field that includes a touch screen and an electronic board having a storage and external device interworking function, which can link a PC to a dedicated pen by capacitive touch. Development of Plug-In, which enables live and VOD lectures and lectures through the development of tools and internet broadcasting, can be considered as the program development and information communication technology fields.

The prior art of these fields has been developed in the form of a body to perform the electronic blackboard and lecture storage function, respectively, but the present invention is a combination of the two solutions in one system to the electronic blackboard and lecture storage Internet broadcasting function It was able to perform the video conferencing function.

1. Hardware technology

Instead of separating the keyboard and mouse from the main body, it should be able to be connected inside the main body to minimize space and weight by attaching them in a drawer type, and can be attached integrally and stably while allowing the angle of the monitor to be adjusted freely as shown in Figure II. It is required to invent a single input board and one output board that can maintain and maintain the weight of a laptop, and connect and store external devices. Invent a motherboard with enough slots to install it. In addition, by developing CODEC Board that can send and receive voice and video in real time during live lecture, it should be able to deliver clear picture quality and voice so that there is no problem in lecture lecture even in low network bandwidth.

2. Software technology

If you connect to the server through the Internet, you can develop a plug-in that allows you to take live lectures in the form of Internet broadcasting and develop a writing tool that can easily write and erase. This writing tool should be switched between mouse function and writing function. Before writing tools, the writing tool can capture VGA screen and execute writing function. On the other hand, the tool should be able to perform writing on any window screen, even writing on moving video.

.

In order to achieve the above object, the present invention is easy to move as a hardware element and can be installed anytime, anywhere, and a small, lightweight yet durable case, VGA card, sound card, and external input for tying the monitor and the body together. Motherboard with at least five slots to connect cards, LCD monitor for electronic board function on the main body, and pen without operating by hand when performing writing / mouse function An electronic pen with a sensor that operates exclusively, a keyboard, a mouse, a bracket for adjusting the angle of the monitor, a power cable, a CD-WRITER for copying stored contents to a CD, a CD-ROM for reading the contents of a CD, a FDD for 3.5 inches, A LAN card is required for internet access.

Software element can control software such as OS basically required when operating PC and lecture / lecture software that can deliver lecture contents by connecting to internet in real time, and can control the capacity and quality of contents to be saved when contents are produced. Hardware control software, playback software required to play stored contents, writing / MOUSE conversion and pen, highlighter, eraser, and partial enlargement functions required to perform writing / MOUSE functions with a dedicated pen .

This system is prepared for the education system in the form of Internet lecture and remote lecture which will be gradually expanded. According to the present invention, all learners can take the desired lecture anytime and anywhere, and in the form of professors who lectured by reflecting the projector on the screen. You will be able to show yourself writing, and the inconvenience of using a laser indicator stick or a wireless mouse will disappear. Instructors can make a textbook using all the sources they want to make into textbooks, so they can develop educational contents with high learning effects. In addition, face-to-face training can be provided to enable the education environment of the high-tech environment to operate effectively.

Above all, this invention allows the instructor to develop content that is easy to create and maximizes the learning effect without special knowledge, and the learner can save time while learning while obtaining the maximum learning effect. I would say there is.

The system up to now is that the instructor has to invest too much time and effort in producing multimedia textbooks and does not utilize it because of the difficulty of the process, so that anyone can easily develop cutting-edge multimedia educational materials. did.

Claims (5)

Unlike the way of adjusting the angle of the monitor in the form of an integrated computer, the design of the system that allows the angle of the monitor to be adjusted in the form of a traditional surface (Fig. . Apparatus to monitor the number of inserted carry out the functions of the electronic blackboard and without using the keyboard, mouse lecture or briefing may monitor type electronic blackboard of the capacitive type that allows to proceed with the keyboard and mouse drawer sluggish in the body and taken out (Fig. Ⅲ ) A palette-type writing program that can perform functions such as pen, highlighter, eraser, enlargement , writing on video, and writing / mouse switching. AGP type lecture storage board that can perform simultaneous VGA screen, analog and digital input signal storage, and audio signal storage. This is a plug-in program that allows anyone who wants to take courses on the cyber lecture homepage that is necessary for internet lectures to take live or VOD lectures in the form of Internet broadcasting when they connect to the server through the authentication procedure.
