Description

METHOD AND DEVICE FOR VISUAL INFORMATION EXPRESSION}

The present invention relates to a visual information display method and an indicator, and more particularly, by providing a writing area into which writing content can be input, and providing a control to adjust the transparency of the writing area, thereby writing the background area and writing area of the writing area. At the same time, the present invention relates to a visual information display method and an indicator having a similar effect to inputting writing content directly into presentation material disposed under the writing area.

Conventionally, the blackboard was a wide board (板) painted in black so that it could be written in chalk, also known as blackboard. Such a blackboard has a problem that a lot of chalk powder can harm the health of the writers. Therefore, a whiteboard using a marker pen has been developed and used widely, instead of using chalk, and in recent years, an electronic device using an OHP film or a projector is also used. It is used a lot.

In the case of using the Over Head Projector (OHP) among the display methods for a conventional presentation, various presentations are produced by using a word processor and outputted on the OH film along with other image files. Graphic techniques are not available and the film is expensive, which is expensive. In addition, for notes or markings for additional explanation, the transparency of OH film was used to give the effect displayed on the displayed material by writing directly on the blank film or directly on the material film with an oil pen. It was inconvenient for presenters and listeners to refer to it by storing it in files. In addition, since the size of the displayed screen is small and the image quality is deteriorated due to the nature of OSP equipment, there is a limit to use it in a large conference room.

Electronic blackboards and projectors are being used as a way to compensate for this. Conventional electronic blackboard is a device that allows you to save, edit, print, and transmit notes on the board as a PC. Among them, a method of projecting onto a screen by using a projector is rapidly increasing with the spread of notebooks. The trend is.

According to the above electronic blackboard apparatus, the lecturer prepares the lecture syllabus into a file that can be read in advance on a computer, prepares it, reads it from the computer, and projects it on the screen for the lecturer by the projector so that the lecturer can view the contents on his monitor. In addition, the content can be viewed on the participant's screen.

In addition, the projector displays the contents of the computer screen in various sizes, from small to large, depending on the model, and because of the excellent image quality, it is particularly advantageous for presentations in large conference halls, and shows programs can be demonstrated. Using points provides the ability to take limited notes directly on the display.

In addition, it is a device commonly referred to as a computer blackboard that has been developed by taking advantage of the above-described copyboard and projector. The computer blackboard has an advantage of being able to directly note on a screen screen (board) using a projector, and includes a projector, a display board, a wired / wireless electronic pen, and a desktop fish.

In particular, if a lecturer needs to write during the lecture, he / she writes out the necessary matters using a mouse and keyboard or an electronic pen connected to the lecturer's computer, and the lecturer writes the contents and the learners write the contents. You can see them together on the screen.

However, the conventional visual information indicator has the following problems.

First, there is a problem in not writing on the presentation material while presenting the material to be presented on the screen.

Second, the above-described note function is software-dependent because it is provided only in software such as PowerPoint, and there is a problem in that functions such as storing writing contents and setting pen thickness are not provided.

Third, in the case of the computer blackboard, the hardware system is complicated, and the initial setting is difficult.

In addition, the size is limited to the display board size due to the touch screen function of the wireless electronic pen has a problem that is not suitable for a large conference room, such as a large screen, and, in particular, there is a problem that the system configuration cost is expensive.

Fourth, in the above-described visual display method, the conventional electronic blackboard is not a device that can be overlaid on the material screen and still uses a marking pen, and consumable use is inevitable.

An object of the present invention for solving the above problems is to provide a visual information display method and indicator that can simultaneously write on the presentation material while presenting the material to be presented on the screen.

Another object of the present invention is to provide a visual information display method and indicator that can be used independently, and can provide functions such as storing writing contents and setting pen thickness.

Still another object of the present invention is to provide a visual information display method and indicator that is simple and easy to set by building a software system.

It is still another object of the present invention to provide a visual information display method and an indicator that can be easily applied regardless of a size, that is, a large screen and a small screen, and the system configuration cost is relatively low.

Still another object of the present invention is to provide a visual information display method and an indicator that provide an advantage of marking on a material screen without using consumables.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the visual information display method includes generating a writing area, adjusting the transparency of the writing area and writing on the writing area. Preferably, the background area of the writing area and the writing area are simultaneously displayed.
