Description

[0001] TABLET TYPE PERSONAL COMPUTER AND PRESENTATION [0002]

The present invention relates to a presentation system having a tablet device for education. More particularly, the present invention relates to a presentation system, which enables a presentation to be performed using a tablet device while a user is moving, The present invention also relates to a presentation system having a tablet device for teaching which can use the pen member as a pointer and can easily store the pen member.

In general, it is preferable to use lectures in the form of images, animations, videos, etc. in order to improve the learning effect because the students can understand more easily by using audiovisual parcels appropriately during lectures. Do.

In the past, in order to obtain such educational effects, there is a method of drawing on the board or explaining text while writing, a method of displaying a picture or text of the card one by one, a method of explaining the drawing, We used the method of carrying out the story by attaching objects or accessories to the fuselage, and the way of performing the puppet show or the play.

However, this method has a problem that the instructor needs to explain the surrounding situation relatively in detail because the preparation of data is very cumbersome and relatively simple and simple data can be used.

Also, if you use fuselage or the like, it is convenient to carry out the story by attaching the pictures one by one, but there is a problem that it is difficult to manage small items.

Recently, a method of displaying slide pictures one by one using a TV or a computer, showing an animation or a movie, or displaying a text and an image edited using a computer is being widely used.

However, animation and movies are relatively complete and easy to attract, but students have to watch passively, and it is not easy for the instructor to give additional explanation in the middle. This is also true of puppets and plays.

In addition, watching dynamic animations or movies rather than static images is more educational because it is more realistic, but because animations and movies are expensive, and because there is no room for change, There is a problem that there is little utility.

Therefore, it is desirable for the instructor to make an image or an animation suitable for his lecture or explanation and use it as educational material, but it is not so easy to produce an image or an animation in reality.

For example, in order to create a required image on a computer, a graphics program is first executed, and then a background image is retrieved and retrieved. Then, the image to be attached to the background is retrieved and loaded. After adjusting the size and orientation of the image, You must copy it.

After activating the background image, you need to paste the image, adjust the position of the image, fix it, and then save the whole picture as a single image file.

However, in the conventional graphics program, it takes a lot of time and time to find the background image and the image to be pasted. In order to find the image, a separate graphic viewer program must be used.

In addition, it takes a lot of steps such as adjusting the size of the image, changing the direction of the image, copying, pasting, etc., and avoiding the production or editing of images directly in the educational field due to such complicated processes.

In particular, since the conventional graphic tool is complicated in the process of producing an image, it can be used only for image production, and it is difficult to utilize it as a multimedia presentation tool that can be used while changing an image in real time according to contents of a lecture.

On the other hand, in order for the instructor to obtain the appropriate image for his lecture, he or she should take pictures or scan with a digital camera, draw pictures directly using graphic tools, or purchase commercially available clip art.

However, in the case of photographing, it is difficult to obtain a desired image, a certain production is inevitable, and there is a problem that a necessary picture is drawn first for scanning.

Also, when drawing a picture using a graphic tool, a lot of skill, time, and ideas are required. Even if a commercially available clipart is used, it is not easy to obtain a desired image, and it is inconvenient to edit it using various characters or small items .

On the other hand, interactive or interactive games such as Go game, Long game, and Board games, which can be enjoyed by two or more people in recent years, have been widely spread, so that two or more pointing devices are connected to one computer, and each pointing device has independent pointers There is a growing need for a computer system that can operate as a computer.

In addition to the game field, there is a growing need for such pointing devices in the field of educational programs or presentations that perform play or storytelling on a computer, or graphics that require complex and precise work.

The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2008-0037263 (published on Apr. 30, 2008, titled as a computer-based storytelling presentation method and multimedia file production method and computer input means therefor) .

Since the data stored by the input means provided on the desk or the like is outputted as an image, the user must be located at a place where the input means is installed, so that the presentation can not be performed. There is a problem that presentation is difficult to proceed.

Therefore, there is a need for improvement.
