Description

Computer system having multi pointing device and method of story telling presentation using the same}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system having a multi-pointing device. More specifically, the present invention relates to lectures, explanations, plays, role plays, storytelling, etc. while arranging, moving, and changing images, animations, and texts on a display connected to a computer in real time. A computer system capable of running presentations.

In general, if the proper use of audio-visual teaching aids can be easily understood during lectures, it is advisable to show lectures in the form of images, animations, videos, etc. in order to enhance the learning effect. Do.

Conventionally, in order to obtain such an educational effect, a method of describing by drawing a picture or writing text on a blackboard, a method of describing and displaying a picture or text of a card one by one, a method of turning a picture of a orbit, a table, text, etc. by one sheet, They used objects, props, storytelling, puppet shows, and theatrical performances.

However, this method has a problem that the instructor has to explain the surrounding situation in detail because the preparation of the data is very cumbersome and the use of relatively simple and simple materials is inevitable.

In addition, if you use a fusion plate, etc., it is convenient to proceed with the story by putting pictures one by one, but there is a problem that it is difficult to manage props.

Due to these problems, recently, a slide show is displayed one by one using a TV or a computer, an animation or a movie is screened, or a text and an image edited using a computer are displayed in units of pages.

By the way, animation or film is relatively high, it is easy to attract interest, but there is a problem that the student must watch passively, and the instructor is not easy to explain additionally. The same applies to puppet shows and plays.

In addition, while watching dynamic animations or movies rather than static images is more realistic, the educational effect is higher. However, animations or movies are expensive and there is no room for change. There is a problem that almost no utility.

Therefore, it is desirable for an instructor to create an image or animation suitable for his lecture or explanation and use it as a training material. However, it is not so easy to produce an image or animation.

For example, to create the required image on a computer, run a graphics program first, then find and load the background image, find and load the image to be attached to the background, adjust the size and orientation of the image, and then place the image on the clipboard. You must copy it.

Next, after activating the background image, you need to paste the image, adjust the position of the image to fix it, and then save the entire image as an image file.

However, in the conventional graphic program, a lot of processes and time are required to find a background image and an image to be pasted, and a separate graphic viewer program must be mostly used to find an image.

In addition, the process of resizing, reorienting, copying, and pasting an image takes many steps. Due to such a complicated process, an education site avoids creating or editing an image directly.

In particular, the conventional graphic tools can be used only for image production because of the complexity of the image production process, and are difficult to use as a multimedia presentation tool that can be used while changing the image in real time according to the lecture contents.

On the other hand, instructors need to take pictures with digital cameras, scan them, draw pictures using graphic tools, or purchase commercially available clipart to obtain the appropriate image for their lecture.

However, when taking a picture, it is difficult to obtain a desired image and some direction is inevitable, and there is a problem in that a required picture must be drawn for scanning.

In addition, drawing a picture using graphic tools requires a lot of skill, time, and ideas. Even when using commercial clip art, it is not easy to obtain a desired image, and even the inconvenience of editing with various characters or props There is this.

On the other hand, as interactive or interactive games such as Go, Chess, and Board games, which can be enjoyed by two or more people, are widely spread in recent years, two or more pointing devices are connected to one computer, and each pointing device independently has a separate pointer. There is a growing need for a computer system that can be operated with.

In addition, the need for such a pointing device is increasing not only in the game field but also in an educational program for performing a play or storytelling on a computer, a program for a presentation, or a graphic field requiring complicated and precise work.

The present invention is to solve this problem, the first object is to provide a presentation means to help instructors to easily prepare an image or a simple animation to be used as educational materials.

Second, the purpose of this course is to provide a means to make the lessons more interesting and colorful, by going from simply displaying images one by one in the presentation process to explaining or telling a story while giving an animation effect to a given image.

Third, it is an object to provide a computer system suitable for such a multimedia presentation.

In order to achieve the above object, the present invention provides a computer main body including an operating system and an application program; A display device connected to the computer main body; A first pointing device and a second pointing device connected to the computer body and generating coordinate signals or event signals to operate the first pointer and the second pointer displayed on the display device independently of each other; And an identification signal adding means for generating an identification signal for distinguishing signals from the first pointing device and the second pointing device, and adding the identification signal to a signal from the first pointing device or the second pointing device.

In another aspect, the present invention provides a connection device interposed between the pointing device and the computer body, the computer port coupled to the computer body; A port for a pointing device to which the pointing device is coupled; Provided is a connection device for a pointing device including an identification signal adding means for generating and adding an identification signal that is differentiated from other pointing devices to a signal input from the pointing device.

The present invention also provides a presentation method using a computer connected to a plurality of pointing devices, the method comprising: displaying a plurality of pointers in one-to-one correspondence with the pointing device on one computer screen; And a pointer controlled by an input signal from each pointing device to independently select or move the objects displayed on the computer screen to each other.

In another aspect, the present invention, the step of connecting the second pointing device to the computer to which the first pointing device is connected; A pointing device recognition module, adding an identification signal to an input signal of the second pointing device and activating the device; Transmitting, by the pointing device recognition module, an input signal of the second pointing device; The present invention provides a storytelling presentation method using a computer, the method comprising moving a second pointer and executing an event independently of the first pointing device.

According to the present invention, a presentation such as a play or storytelling can be easily performed on a computer screen. For example, while the instructor holds the first and second pointing devices in both hands, the instructor can select an object in the program and perform an interactive role play or storytelling.

In addition, by using a multi-pointer, the movement distance of the pointer can be reduced, thereby reducing work time and improving work efficiency, and improving user convenience. In addition, the use of both hands can reduce stress intensity because work stress is dispersed.

In addition, two or more people can play interactive role-plays or play interactive games such as Baduk, Shogi, and Martial Arts through one screen while holding the first and second pointing devices.

Also, if you connect two monitors and two pointing devices to one computer, you can play interactive games such as Go, Shogi, and other board games using your own monitor and pointing device.

Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention.

First, the storytelling presentation method according to the embodiment of the present invention proceeds in the following manner.

That is, a program recording a storytelling presentation method according to an embodiment of the present invention is run on a computer device such as a notebook computer or a desktop computer, and various images such as props and actors are arranged on a screen connected to the computer device. Or, mark and present a lecture or explanation. Objects such as props and actors may be displayed on a preselected background image.

Meanwhile, in the present specification, a two-dimensional or three-dimensional image such as a character or a prop displayed on a background image, an animation or text, etc. will be collectively referred to as an 'object'.

The position, size, and direction of the object can be changed by the instructor in real time according to the contents and development of the lecture, and can be explained or expanded while changing or moving the object's color and contrast. If necessary, the background image can be changed in color, contrast and weather.

In addition, an animation effect may be displayed by displaying an image changed according to a direction, distance, or time of moving an object.

In addition, text, diagrams, educational materials, etc. can be placed on the screen and explained, and various background images can be prepared and the above process can be performed while sliding one screen at a time.

This presentation method can induce high concentration and interest of learners by making simple changes or animation effects such as showing and moving actors rather than simply showing pictures, tables, and texts.

In addition, unlike produced for unilateral viewing such as plays, puppet shows, animations, and movies, it has the advantage of showing images or animations in real time according to the progress of explanations, stories, conversations, etc. To help.

Hereinafter, a method of expressing an image in real time on a presentation screen and a method of providing an animation effect will be described in detail.

1. Image Representation Method

First, a description will be given of a method of expressing an image in a picture form using various objects on the presentation screen.

The presentation program according to an embodiment of the present invention provides various types of background images and objects in the program itself, so that the user can easily express and produce images in the form of pictures by importing them.

In addition, such a background image and an object are stored in a storage unit in a kit form that can be attached and detached from the outside of the computer, and the program can be set in such a manner as to be loaded on a program of the present invention and displayed on a screen.

In addition, only a basic program may be installed in the computer, and the background image and the objects may be provided by a streaming method or a download method from a service server connected through the computer and the internet network.

Hereinafter, a presentation method according to an embodiment of the present invention will be described on the assumption that a basic background image and an object are mounted in the program itself.

1 is a presentation screen 10 provided by a presentation program according to an exemplary embodiment of the present invention, wherein the presentation screen includes a canvas 11 displaying a background image or an object selected by a user, The tool selection window 12, the object group selection window 13, the color selection window 14, the special effect selection window 15, and the like are arranged around the periphery.

The tool selection window 12 displays a number of buttons and a background setting button at the same time, such as line drawing, figure drawing, font size control, saving, loading, and color filling.

Since the presentation program according to an embodiment of the present invention provides various background images or objects on its own, a plurality of object groups having a common feature in advance may be used for various types of objects so that the user can easily search and select the stored background images or objects. It is desirable to classify.

For example, the object group selection window 13 includes a folder search button that can be called from a folder that associates a plurality of object group icons representing each object group with the remaining object groups that cannot be displayed on the screen due to the limitation of space. Is displayed.

The color selection window 14 is equipped with a plurality of color buttons such as red, blue, yellow, black and green so that the user can select a desired color without complicated manipulation, and also provides a color adjustment menu for finer color adjustment. do.

The special effect selection window 15 is for giving a special effect such as snow or rain after displaying a background, an object, etc. selected by the user on the canvas 11.

Hereinafter, a process of expressing various object images according to the story development on the presentation screen will be described in order with reference to FIGS. 2A to 2H.

First, when the presentation program according to the embodiment of the present invention is driven, the presentation screen as shown in FIG. 1 is displayed, and when the background setting button (square display) of the tool selection window 12 is clicked on as shown in FIG. 2A, the canvas is displayed. At the top of (11), a background selection window 16 including a plurality of background icons visually displayed is displayed.

Subsequently, when the user selects one background icon in the background selection window 16, the selected background image is displayed on the canvas 11 as shown in FIG. 2B.

The user must select an object such as a character, text, props, etc. to be represented on the background image according to the presentation development situation. For this purpose, a desired object group icon in the object group selection window 13 is shown in FIG. For example, select an icon that looks like a log cabin.

When the user selects one object group icon, the object selection window 17 is displayed on the top of the canvas 11 instead of the background selection window 16, and all objects included in the selected object group are displayed on the object selection window 17. Is displayed as an object icon. The user can select a desired object by clicking one object icon among them.

As such, when one object group icon is selected in the object group selection window 13, all the objects belonging to the object group are displayed on the presentation screen so that the user can visually check them. Is a distinctive feature.

In the conventional method, a process of (1) selecting an open menu or icon to import an object image on a graphic tool, (2) finding a folder, and (3) checking the included image file by opening the folder Select the desired object through the process of selecting the image file, pressing the OK button, and opening the selected image file.

Even if the image tool or browser is supported within the graphic tool, the above steps (1) and (2) must be carried out. If the image viewer or browser is not supported, run the image viewer or browser program to load and display the entire image. Finding an image of an object requires a lot of time and processing.

In addition, the conventional method is not suitable for use in a presentation process in which various objects are frequently called because the same process must be repeated from the beginning even after selecting one object image and finding another object image.

On the other hand, in the presentation program according to the embodiment of the present invention, when the user selects the representative icon button of the object group displayed on the presentation screen, all object images in the group (or folder) are loaded on the program and the object selection window is displayed by the viewer. Displayed at (17), the user then clicks one of the displayed object icons to terminate the image selection process. (dump and select method)

In addition, as described above, the presentation program according to the embodiment of the present invention provides a folder search button to search for an object not included in the object group displayed on the presentation screen.

Therefore, when the user selects the folder search button, a number of folders are displayed on the screen, and the user has to find a folder including a desired group of objects.

After searching and selecting the folder, icons of all objects in the selected folder are dumped in the object selection window 17 on the screen, and the object is selected by selecting an icon of the desired object. .

According to the object selection method of the present invention, since a variety of objects are displayed on the presentation screen so that the user can visually check easily, the procedure of selecting one image and then another image is very simple.

On the other hand, a plurality of object icons displayed on the object selection window 17 is selected by pressing the mouse pointer, and once one object icon is selected, it is preferable to set the object icon to remain selected even if the user releases the mouse button. .

Then, when the user places the mouse pointer at the desired position of the canvas 11 and presses the mouse button and pulls the button after the desired direction and length as shown in FIG. 2D, the selected object is placed on the canvas. (11).

At this time, the size of the object is automatically adjusted to the size of the rectangle facing the starting point and the ending point of the mouse pointer. When the size of the object needs to be resized, the preset zoom button is set on the keyboard or other input device.

If you need to reposition an object, ie if you need to move it, use the mouse or the arrow buttons on a keyboard or other input device.

In contrast to the press and pull method, the conventional drag and drop method is to (1) select an object by pressing the mouse button, and (2) keep the mouse button pressed to select the selected object. Dragging to a location, (3) Release the mouse button to drop the selected material to the desired location.

However, in the conventional drag and drop method, since the object is moved to the original image size, it is necessary to adjust the size separately after placing it at a desired position and to adjust the direction separately because the object is moved to the original image state.

Therefore, there is a problem that it is not suitable for applying to a multimedia presentation because the object selection and movement have to go through several processes and continuity is broken.

On the other hand, in the press and pull method of the present invention, it is not necessary to keep pressing the mouse button to the desired point by selecting the object, and after selecting the object, after placing the mouse pointer on the desired starting point of the canvas and pulling the desired length in the desired direction, Just release the mouse button at the endpoint. This makes selecting, positioning, and resizing objects much easier.

In addition, as described below, the direction of the object image may be easily changed according to a pulling direction.

In addition, since the previous object is still selected until the user selects another object, the same object can be displayed infinitely on the canvas 11 without a separate object selection procedure by using a mouse operation. It is advantageous.

In addition, the objects can be placed independently on the background image so that each object can be moved independently, which can be used for presentations such as basic mathematics education.

The background image and the object to be displayed thereon are preferably classified and provided by a specific story or theme in the program so that the user can easily access the background image.

Table 1 below is a classification table illustrating background images and objects that can be used in storytelling about 'General Yi Sun-sin'.

In other words, the background image includes military, sea, straits, maps, land, decks, ships, etc., and objects include main characters (such as Yi Sun-sin and Won Kyun), ships (turtle ships, and warships), soldiers, farmers, and natural objects. Or you can include structures (castles, islands, rocks, seagulls, etc.), battles (such as artillery shots, javelin throws, etc.), and horses.

TABLE 1

 Theme: Admiral Yi Sun-sin (story book or specific story) Background image Gunyoung 1, Gunyoung 2, Sea, Strait 1, Strait 2, Map, Land, Deck, Inside Line   Object ① Main characters: Yi Sun Shin 1, Yi Sun Shin 2, Won Kyun, etc. ② Types of Ships: Turtle Ship, Dwarf Boat, Fishing Boat ③ Soldiers, etc. Figures: training, farmers, etc. ④ natural objects, structures, etc: castles, islands, rocks, seagulls, etc. ⑤ Battle: Shooting guns, throwing javelin, etc. ⑥ Other: Horse riding, food movement, evacuation, etc.

The user can designate the background image prepared in this way. However, rather than letting the user select a necessary background image, the background image can be set in order to display the appropriate background image in order according to the story development order or scenario. For example, if the user presses the slide button, setting the background image such as the appearance scene, the sorting scene, the ambushing scene, the attacking scene, and the winning scene in order may prevent confusion of the instructor.

Table 2 below is a classification table showing the background image and objects for storytelling or presentation about 'country life'.

TABLE 2

Theme: Rural life (themes that can make a story) Background image Mountains, valleys, fields, streams, rice fields, fields, lakes, houses, pastures, etc.   Object ① Moving people: walking, carrying luggage, etc. ② work, other: threshing, shoveling, building, etc. ③ Vehicles: tractors, wagons, carts, trucks, etc. ④ Horticultural crops: Apple tree, Chinese cabbage, etc. ⑤ Animals in Motion: Dogs, Frogs, etc. ⑥ Flying birds, insects: sparrows, dragonflies, etc.

Background images may be a variety of images, such as mountains, valleys, fields, streams, rice fields, fields, lakes, homes, ranches, etc., various objects such as people, vehicles, crops, animals can be displayed on the background image.

At this time, when the object is selected and pasted on the background image, a more vivid effect can be obtained by providing a change of direction or an animation effect. To this end, when selecting and pasting objects in groups ① and ⑤ in Table 2, the image can be switched in the left and right directions, and when selecting and pasting objects in ⑥, the images can be switched in all directions. .

In addition, when selecting and moving objects in ①, ③, or ⑤, the image can be switched or animated along the x-axis. When selecting and moving objects in ⑥, the image can be switched along the y-axis. You can also add animation effects.

Such image switching and animation techniques will be described later.

Meanwhile, in the presentation program of the present invention, in addition to providing such a background image or an object in the program and providing a function for the user to retrieve and express it in real time, the text may be retrieved and displayed.

When importing text, it is desirable to load the parts in order according to the lecture or story order. For this, for example, the Enter key can be used as a text division unit.

Here, the text may be provided by the program itself, may be a file name of an imported object, or may be input by a user.

The text can also be positioned and resized by press and pull.

Meanwhile, the presentation program of the present invention provides a means for easily changing the direction of the selected object.

That is, after selecting the desired object, the direction of the image is differently displayed according to the direction in which the mouse pointer is positioned at the desired position on the canvas 11 and the pulling direction after the mouse button is pressed.

For example, as shown in FIG. 3, when the mouse pointer moves in the (+ x, -y) direction based on the initial position (start point), the normal image is displayed, and when the mouse pointer is moved in the (+ x, + y) direction, the up and down When the image is inverted, the image is inverted left and right when moved in the (-x, -y) direction, and the image is inverted in the up, down, left, and right directions when moved in the (-x, + y) direction.

For convenience, the normal image may be displayed in the + direction based on only the x component in the moving direction, and the image inverted left and right may be displayed in the − direction. Alternatively, a normal image may be displayed in the + direction based on only the y component in the moving direction, and an image inverted up and down may be displayed in the − direction.

Such a redirection technique may be applied to an object such as a person, a ship, a vehicle, a ship, or an animal illustrated in Table 1 or Table 2 above.

Conventionally, in order to change the direction of an image, it is very cumbersome to use a redirection menu provided by a graphic tool or to select a redirection direction or angle after bringing up a redirection dialog in the edit menu.

Therefore, in a multimedia presentation where real-time expression is important, the redirection method as the present invention can be used much more effectively.

The direction of the object already displayed on the canvas 11 can be switched using a redirection key preset in a keyboard or other input device. However, in the present invention, the mouse pointer is moved on the object as shown in FIG. 4. The present invention proposes a redirection method for displaying object images of different preset directions according to the directions.

For example, after dividing into four angular sections based on the center point of the original image (a), if the mouse pointer moves in the angular range of section (I), the normal image is displayed. Display the image (b) rotated in the direction of 180 degrees in the normal image, the image (c) rotated counterclockwise 90 degrees in the normal image when moving in the angular range of section (III), (IV) section Moving in the angular range of displays the image (d) rotated 90 degrees clockwise. Of course, the angular range and the image direction can be further subdivided.

This method can give a more vivid visual effect not only in changing the direction of the stationary object but also in moving the object. For example, when moving a dragonfly character using a mouse as shown, the head direction of the dragonfly is changed every time the moving direction is different, which gives a very realistic feeling.

This redirection technique also simplifies the user's operation, making it easy for the instructor to demonstrate effective animations in real time during a multimedia presentation.

2E to 2G illustrate a process of additionally displaying various objects on the same canvas 11.

This presentation program enables you to present realistic lectures by displaying the appropriate objects on the screen according to the situation during lectures or stories.

If necessary, the color of the object or text input through the color selection window 14 may be changed, and the snowing effect may be given as shown in FIG. 2H by using the button provided in the special effect selection window 15. In addition, rain, thunder, lightning and other effects can be.

The method for displaying such special effects includes a method of displaying directly on an object and a background image, and setting a transparent layer on the front of the screen, and changing the contrast, color, rain, snow, sun, clouds, wind, and lightning on the transparent layer. Another way is to display images or animations for special effects like thunder.

This special effect may be represented by using an image or animation supported by the program of the present invention. In addition to these special effects, a user may directly write text, draw a picture, or give a graphic effect by using a mouse or an electronic pen. It may be.

After the above process is completed, the image in the form of a picture consisting of the background, various objects, special effects, etc. on the canvas (11) is completed, by pressing the Save menu of the tool selection window 12 to save the completed picture as a single image file Alternatively, the user can automatically save the file in a designated name in real time by using the save button of the input device.

Meanwhile, the name of the object displayed on the presentation screen may be displayed in Korean, English, and the like. For this purpose, in the program of the present invention, when the instructor selects a specific object, the object is displayed on the upper left side of the presentation screen as illustrated in FIGS. 2D to 2H. A text window in which the name of the object appears is set.

The text displayed on the text window may be displayed on the background image by a press and pull method after the user clicks and selects the mouse in the same manner as the image display process.

Since the text can selectively display Korean or foreign languages, the program of the present invention can be very useful for language learning of infants and children.

For example, if one object icon is selected in the object selection window 17, the name of the object is displayed in the upper left text window in Korean or foreign language, and drag and drop, press and pull, select and locate are possible. After displaying the object on the presentation screen in all manners, the text (Korean or foreign language) is displayed next to the object in the same manner, which can be usefully used for word learning.

For a more vivid effect, when the mouse pointer is placed on an object or text and the mouse button is clicked, the name of the object or the pronunciation of the text is output as a sound.

In addition, when a mouse pointer is placed on a specific object and a mouse button is pressed, a sound (for example, animal cry) representing the object is output, and when the mouse button is released, the sound may be terminated.

Also, to avoid having to keep pressing the mouse button when moving the object, when you put the mouse pointer on the object and click the mouse button, the object is selected, and the mouse pointer is not shown to show the selected fact. Only objects can be made active and visible.

If the mouse button is clicked again after the object reaches the desired position, the selected object is placed in the final position and the mouse pointer is displayed again.

For example, if you click on the Go egg, the mouse pointer is not shown but only the Go egg is displayed. In this state, you can move the go egg to the desired position even without pressing the mouse button continuously. At this time, a specific sound effect or animation effect may be given at the moment of selecting an object such as a game ball.

By applying the above-described image expression method in the presentation program of the present invention, the following effects can be obtained, so that the presentation can be easily performed effectively.

1. You can easily find the background screen and enter it easily.

2. You can easily find objects and props to be displayed in the background and easily enter them.

3. Resizing objects is easy and intuitive.

4. The direction of the object is easy and intuitive.

5. You can paste the selected object on the background simply and several times.

6. The editing process and image production time can be significantly reduced.

7. People who do not draw well can easily edit to get the desired image.

8. Entering prepared text is easy and simple.

9. You can automatically adjust the font of the text you enter.

2. How to express animation

The above-described image representation method is for producing a static image in the form of a picture on the canvas 11 using a background image or an object provided by the presentation program of the present invention or imported by a user.

However, to make the multimedia presentation more realistic, it is desirable to add dynamic animation properly.

In this context, it is a simple form of animation that changes the direction of the object according to the direction of the mouse movement or adds special effects such as snow, rain, thunder, and lightning.

This section further describes how to give actual moving effects to the objects displayed on the presentation screen.

First of all, in the conventional animation technique, a screen (or canvas) sized image of a specific object is changed a little and then made into a single file, which is displayed by displaying several to several tens of images per second in order. This is how the object feels as if it is moving. That is, the conventional animation technique may be referred to as a method of displaying a changed image on a screen at predetermined time intervals.

However, this method is not suitable for improvizing a simple animation effect appropriate to the situation during the multimedia presentation, although it takes a lot of production time because the image of the canvas 11 should be produced in advance.

The presentation program according to an embodiment of the present invention provides a method for realizing a simple animation effect on each object in real time while performing a presentation.

First, after selecting and displaying a predetermined object on the background image of the canvas 11, when the user grabs the displayed object using a mouse pointer and moves it in an arbitrary direction, an animation expression method for displaying a changed image at every predetermined distance is provided. do.

For example, as shown in FIG. 5, when the reference position of the object passes through the x1 + a point when the object is pulled in the x direction with a mouse while the reference position of the object is x1 point on the x coordinate. Display the deformed image and set to display the original image again or the second deformed image when passing through the x1 + 2a point continuously.

Here, a is a randomly determined distance in the x direction and should be set within a limit that can give a minimum animation effect. Of course, the original image and the modified image of the object should be stored mapped to each other.

Accordingly, the object of FIG. 5 is changed to various images and displayed or appears to run in the process of pulling in the x direction using a mouse. Of course, the same method can be applied to the movement in the y direction.

That is, the changed image may be displayed again when moving in the x direction and then moving in the y direction. When the mouse pointer continues to move in the x direction, the effect of jumping in the x direction is given in the above-described manner, and when the direction of the mouse pointer changes in the y direction, the object in a different direction is displayed as described in connection with FIG. The changed image may be displayed according to the set distance.

The executed animation screen (including the background image and each object) can be captured as a set number of frames per second and saved as a single animation file. In this case, the sound effect and the microphone input sound can be saved together.

In addition, while the plurality of objects are sequentially disposed on the background image, the entire image may be captured every predetermined time interval or every time a new object is added, and the plurality of captured images may be stored as one animation file.

In this animation expression method, since the image changes according to the moving speed of the mouse pointer on the canvas 11, a very natural animation effect can be obtained with only a few images.

In addition, it is possible to give a partial animation effect to each object, thereby enabling a simple theatrical presentation on the computer screen.

Animation expression is not necessarily limited to dynamic effects such as walking, running, flying, etc., and can be applied to various fields such as facial expression change, emotion change, color change, size change, and direction change.

For example, when the mouse pointer is placed on an object such as a person or an animal, the movement of the mouth or the limbs can be expressed. This may be implemented by sequentially displaying a plurality of consecutive transformed images mapped and stored with the original image of the corresponding object in a short time.

On the other hand, if the instructor automatically saves the details of the execution during the storytelling or presentation in the above-described manner with respect to a specific topic as a multimedia executable file or an animation file, the same storytelling may be performed afterwards.

Table 3 exemplifies the process of creating a single multimedia executable file by storing the execution history as the storytelling proceeds.

TABLE 3

order Contents location size action Progress time One Background Image1 (0, 0) full screen start 2 Sound1 10 sec 3 Object 1 (a, b) (c x d) Button click 1 sec 4 (a + n, b) n = n + 5 20 times 0.1 sec x 20 5 Text1 (i, j) font name font size 2 sec 6 Background Image2 (0, 0) full screen Button click

First, when the background image 1 is displayed, the relevant information, for example, coordinates (0,0) of the reference position and the image size (full screen) are mapped with the background image 1 and stored.

If background image 1 appears with the appropriate background music, you can create a more vivid multimedia file, so you can determine the sound 1 to be output with background image 1 and set a time (for example, 10 seconds) to execute it.

Subsequently, information about the objects displayed in the background image 1 is sequentially stored.

For example, when the object 1 is displayed, the coordinates (a, b) and the size (c × d) of the reference position are mapped to the object 1 and stored.

The time point at which the object 1 is displayed in the multimedia executable file may be set to an arbitrary time point after the background image 1 is displayed, or may be set to be displayed when the instructor clicks the operation button.

The time item (1 second) in Table 3 is the minimum time that Object 1 lasts on the screen. Even if two buttons are pressed in succession, Object 2 is displayed on the screen after Object 1 lasts for at least 1 second. will be.

If the instructor moves the object 1 in the x-axis direction and alternately displays the normal and changed images of the object 1 to give an animation effect, the coordinates of the object 1's reference position may be used when creating the executable file. + n, b), set n = n + 5 to move the reference coordinate position by 5 pixels in the x direction, and allocate 0.1 seconds of time to the coordinate movement of one unit.

Therefore, in the produced executable file, object 1 moves coordinates in the x direction every 0.1 seconds to alternately display the changed image. If the number of coordinate shifts is 20, for example, the animation takes about 2 seconds.

Next, when the instructor selects text 1 corresponding to a specific object and displays it next to the specific object, related information such as a reference position coordinate (i, j), a font name, a font size, and a minimum holding time (eg, 2 seconds) Save with text 1 above.

After the storytelling or presentation related to the background image 1 through the series of processes, the instructor selects the new background image 2 and displays it on the screen, and the executable file production program stores information such as the reference coordinates and size of the background image 2 do.

In addition, the background image 2 may be displayed after a predetermined time after the object selection and movement on the background image 1 is completed, or the background image 2 may be set to appear when the instructor clicks the operation button.

The storytelling or presentation contents conducted by the instructor through this series of processes are produced as a single multimedia executable file or animation file, so the instructor can easily use the produced files without repeating the same storytelling or presentation from the beginning. You can do storytelling or presentations.

3. Input device for presentation

In general, a multimedia presentation system includes a computer that executes a presentation (including a laptop, an IPTV, etc.), an output device such as a screen and a speaker connected to the computer, an input device such as a keyboard, a mouse, a microphone, and the like.

However, in order to conduct lectures or stories in real time using the above-described digital image or animation production program during a multimedia presentation, it is particularly desirable to provide an input device that can be easily manipulated by an instructor.

FIG. 6 is a diagram illustrating an example of an input device 20 according to an embodiment of the present invention, and includes various buttons suitable for conducting a lecture while showing an image or an animation using the above-described program.

A plurality of button groups are arranged at the center, and the button groups include, for example, a screen switching button group 21, a sound effect button group 22, a special effect button group 23, and a color conversion button group 24. ), The object conversion button group 25, the object moving button group 26, the object rotation button group 27 and the like.

The screen conversion button group 21 is for screen switching or resizing and includes, for example, a button such as 'previous, next, screen', and the 'screen' button serves to convert the canvas into a full screen or a normal screen. Do it.

Sound effect button group 22 includes a 'small, large' button for volume control, a 'repeat' button for repeated listening, and 'effect sound' button.

The special effect button 23 is to give a special effect on the screen and includes a button such as 'wind, snow, rain, thunder lightning, clouds' and the like.

The color conversion button group 24 is for changing the color of the screen or an object, and includes buttons such as 'red, green, blue, light, dark, and gray', and the 'color' button that can be restored to the original color. Can be placed.

Object conversion button group 25 is for adjusting the size or aspect ratio of an object such as a prop or an actor, and includes buttons such as 'large, small, fat, fat, large, small' and the like. You can have a 'original' button that can be restored to size.

In addition, the object movement button group 26 is to give a position movement or animation effect of the object and includes a button such as 'left, right, up, down' and the like.

The object rotation button 27 is for rotating an image of an object, and includes an 'up and down' button for inverting an image up and down, and an 'left and right' button for inverting an image left and right, for example, in a clockwise direction each time it is pressed. It includes a 'rotate' button that rotates the image by 15 degrees.

In addition, the input device 20 may be used with a mouse or a joystick, and in preparation for this, it is preferable to provide a mouse pad 28 or install a joystick around the button group.

In order to utilize an image and animation production program according to an embodiment of the present invention, it is also possible to manufacture a separate input device 10 as shown in FIG. 6, but it is possible to set and use the keypad 30 as shown in FIG. 7 in a general keyboard. It may be.

In FIG. 7, screen is used to display an image drawn on a canvas on the image presentation screen in full screen or to return to the original presentation screen, and up and down respectively represent a previous screen and a next screen.

In addition, C (color) is for controlling the brightness of a screen or an object, and after adjusting a brightness target (screen or object), pressing C button together with + button or-button to adjust brightness. At this time, you can press C button while pressing + or-button, or press + or-button after pressing C button.

All colors can be represented by RGB values, and on a computer, R (red), G (green), and B (blue) are divided into 256 levels from 0 to 255, respectively. With increasing brightness.

Therefore, when the RGB value of the screen or object is currently RGB (A, B, C), for example, if the user presses the + button once together with the C button, the RGB value increases by the set value (for example, 10 steps). The brightness increases with (A + 10, B + 10, C + 10), and pressing the-button once decreases the RGB value by the set value (for example, 10 steps). C-10), the brightness decreases.

In addition, the color of the screen or the object can be adjusted using the method of adjusting the RGB value. For example, pressing the + button together with the R button of the keypad 30 increases the R value by the set level from the RGB value, thereby changing the screen or object to a brighter red color.

Conversely, if you press the -button together with the R button, the red value of the screen or object can be reduced by decreasing the R value from the RGB value by the set level.

In this case, pressing the + button or the-button together with the R button may increase or decrease the R value by the set level in the RGB value and simultaneously decrease or increase the G value and the B value by the set value.

Likewise, by pressing G button or B button together with + button or-button, you can change the color of screen or object by changing G value or B value.

The arrow buttons ↑, →, ↓, ←, ↙, ↘, ↗, and 은 are for moving the object, and when pressed, the selected object can be moved in the direction of the arrow. As in the case of using the mouse in 4, the direction of the object can be changed in the direction of the arrow.

You can also use the + button or the-button and the arrow buttons together to adjust the size of the object. For example, pressing the ↑ and + buttons increases the height of the selected object, while pressing the-button and the ↓ button decreases the keys. Also, pressing the → and + buttons will make the object fat and pressing the ← and button together will make the object slender.

Pressing the O and + buttons will increase the size of the object, and pressing the O and-buttons will make the object smaller.

At this time, you can press the + or-button while pressing the arrow button or the O button, or conversely, press the arrow button or the O button while pressing the + or-button.

In addition, the sound button plays a unique sound effect that is set for each object or other special sound effects (such as the sound of an object moving or colliding with another object).

If you press the sound button, the set sound is repeatedly played. If you press the + button, the sound increases and if you press the-button, the sound decreases.

In addition, rain, snow and wind are for special effects and are displayed with increased or decreased intensity when pressed with the + button or the-button, respectively.

You can also press the ctrl and rain buttons together to display the thunderstorm.

The save button is for saving. The save button can be set to save the animation produced in the program, and pressing the ctrl and save buttons together saves the current image.

It is desirable to be able to select whether or not to use as a general numeric key.

In addition to the keypad-type input device, a touch screen input device may be provided or an input device may be embedded in a program in a touch screen computer.

This has the advantage of being useful for learning and entertainment of infants and lower grade children because they can intuitively select and move objects through the screen without looking at the complicated keypad.

4. Multi Pointing  Device

On the other hand, when the play or storytelling in the above-described manner is performed through a general computer system in which only one pointing device is connected to the computer body, only one object can be moved or selected at a time. Has a limit.

Therefore, in the embodiment of the present invention, in order to overcome these limitations and to improve the effect of play or storytelling on a computer, two or more pointing devices are connected to one computer, and each pointing device operates independently of each other. Suggest.

The pointing device is provided with a motion detecting means such as a ball or light and an operation means such as a button, and serves to transmit the coordinate information obtained from the motion detecting means and event information generated by the operation to a computer main body. Joystick, trackball, touchpad, and the like.

9 is a schematic configuration diagram of a computer system 100 according to an exemplary embodiment of the present invention. The computer body 130 and the first pointing device 110 and the second pointing device 110 are input means connected to the computer body 130. Pointing device 120, and a monitor 140 that is an output means connected to the computer body 130.

In the present invention, two pointing devices 110 and 120 are connected to one computer main body 130, and first and second pointers 141 and 142 are displayed on the monitor 140, so that the first and second pointing devices 110 and 120 are displayed. Each feature is characterized by independent operation.

It is also included in the scope of the present invention that three or more pointing devices operate separate pointers, but the following description will be limited to the case where two pointing devices are connected as shown in FIG. 9 for convenience.

Each of the pointing devices 110 and 120 generates coordinate information related to movement of each pointer 141 and 142 and event information such as a button click of a user and transmits the generated event information to the computer main body 130.

The computer main body 130 includes a processor 133 for processing information according to a program, a main memory 134 for storing system operating programs and various application programs, a RAM 135 for temporarily executing a program or storing data, and a monitor. And a monitor connecting portion 136, each providing a connection interface with the 140.

In addition, the first and second pointing device 110, 120 includes a first and second pointing device connecting portion (131, 132) for providing a connection interface.

The computer system 100 may be provided in the form of a desktop computer, a notebook computer, a personal digital assistant (PDA), a portable multimedia player (PMP), a play station portabl (PSP), a navigation device, a game console, and a digital TV.

Looking at the computer system according to an embodiment of the present invention from the program point of view can be represented as a block diagram as shown in FIG.

That is, the operating system program 200 providing a GUI between the user and the computer may include a first pointing device recognition module 210, a second pointing device recognition module 220, a monitor interface module 230, various application programs 240, and the like. It is configured to interlock.

The first and second pointing device recognition modules 210 and 220 process a signal input through the first and second pointing device connection units 131 and 132, respectively, to generate a pointer on the monitor 140, and detect a movement or a click operation. The program serves to move the coordinates of the pointers 141 and 142 or execute a specific program.

The first and second pointing device recognition modules 210 and 220 may be provided in one program but may be provided as independent programs.

Meanwhile, when the first and second pointing device recognition modules 210 and 220 are arranged in the same layer as the application program 240 as shown in FIG. 10, the first and second pointers 141 and 142 may all move over the entire monitor screen. .

However, when the position and the role of the second pointing device 120 are the same as the position and the role of the first pointing device 110 in the recognition module, the second pointer 142 may operate the O / S of the computer like the first pointer 141. In general, the first pointer 141 is used at the O / S level, since it may cause unnecessary confusion of the user, such as executing a plurality of programs simultaneously using a plurality of pointers by operating the entire embedded program. For example, it is more desirable to utilize multi-pointers only when running certain applications on the computer that support storytelling, theatre, interactive games, and the like.

As described above, when the multi-pointer is to be used only when a specific application is executed, as shown in FIG. 11, the second pointing device recognition module 220 is included in or linked to the specific application 240. It should be arranged so that it can be executed only when a specific application 240 is executed.

Therefore, although the first pointer 141, which is a basic pointer, is generally moved throughout the program including the O / S, when a specific application is executed, the second pointing device recognition module 220 is activated, as shown in FIG. Inside the execution screen, a second pointer 142 is generated and displayed.

In this case, the second pointer 142 may move only inside the execution screen of the corresponding application program, whereas the first pointer 141 is controlled by the first pointing device recognition module 210 which is a basic recognition module, so Not only can it move across, it can also operate within the execution screen of the application.

Accordingly, the two activated pointers operate independently of each other in the execution screen.

Coordinate information or event information generated by the first and second pointing devices 110 and 120, respectively, and input into the computer main body 130, may be first or second pointers 141 and 142 by the first or second pointing device recognition modules 210 and 220, respectively. ) Is used to update the location or to execute the application 240 or other applications.

Meanwhile, the first pointer 141 is controlled only by the signal processed by the first pointing device recognition module 210, and the second pointer 142 is controlled only by the signal processed by the second pointing device recognition module 220. However, it is preferable that one pointing device recognition module recognizes and distinguishes the first and second pointing devices, respectively, to perform signal processing. For example, one pointing device recognition module (e.g., a mouse driver) included in the O / S may be connected to a computer, or may be arbitrarily assigned or according to whether an identification signal is used. Can be distinguished.

In order to prevent confusion of the user, the first pointer 141 and the second pointer 142 preferably have different colors or shapes.

Hereinafter, a method of distinguishing and pointing a pointing device connected to the computer main body 130 into the first pointing device 110 and the second pointing device 120 will be described with reference to FIGS. 9 and 10.

The first method is a method of differentiating electrical signals generated by the first and second pointing devices 110 and 120, respectively, and transmitted to the processor 133 of the computer body 130.

For example, the identification signal is added by adding an identification signal (for example, a predetermined bit pattern) that can be distinguished from the first pointing apparatus 110 to a signal generated and input by the second pointing apparatus 120. The input signal may be processed by the second pointing device recognition module 220.

Although the identification signal may be generated inside the second pointing device 120, as shown in FIG. 13, the connection device 150 having identification signal adding means (not shown) for generating and adding a predetermined identification signal. May be interposed between the second pointing device 120 and the second pointing device connection part 132.

As such, when the processor 133 of the computer body 130 passes the connection device 150 and processes the input signal to which the identification signal is added through the second pointing device recognition module 220, the second pointer 142 on the monitor. ) Can be controlled independently of the first pointer 141.

The connection device 150 may be connected to one pointing device 120 one-to-one, but may be manufactured so that both the first and second pointing devices 110 and 120 are connected to each other.

For example, as illustrated in FIG. 14, first and second ports (not shown) to which the first and second pointing devices 110 and 120 are coupled to the connection device 150, and the pointing device connection portion of the computer body 130 ( A third port (not shown) coupled to the 131 may be installed.

The connection device 150 includes, for example, an identification signal adding means (not shown) for adding a predetermined identification signal to a signal input through the second port. In this case, the connection device 150 may alternately transmit the signals input from the first pointing device 110 and the second pointing device 120 to the computer main body 130 by a time division or the like, and the computer main body 130. In the present invention, the signal to which the identification signal is added is recognized as a signal of the second pointing device 120.

In the second method, the processor 133 is configured to recognize the first and second pointing device connecting parts 131 and 132 separately, and the signals input through the respective connecting parts 131 and 132 are first and second pointing device recognition modules 210 and 220. ) Can be processed separately.

This may be implemented by connecting the respective pointing device connectors 131 and 132 and the processor 133 by using separate lines.

The third method is a method of distinguishing the first and second pointing devices 110 and 120 according to the order in which the recognition module is connected to the computer main body 130.

For example, the first pointing device 110 may be recognized as a computer booting process, and the second pointing device 120 may be connected and recognized later. In the case where the processor 133 is connected at the same time, the processor 133 may randomly select the two to designate the first and second pointing devices 110 and 120.

Recognition module that performs this division can be placed anywhere in the operating system, the execution program, the connecting device.

As such, when two pointing devices 110 and 120 are connected to the computer main body 130 to operate two pointers independently, the computer body 130 may have a more vivid effect when performing role play or storytelling on the computer.

For example, as illustrated in FIG. 15, a teacher or a parent holds the first and second pointing devices 110 and 120 in both hands and selects and operates a first object (dinosaur) using the first pointer 141. The second pointer 142 may be used to select and operate a second object (person) to maximize the effect of storytelling or play.

Such a multi-pointer can also be useful in interactive or interactive games such as Go, Shogi.

FIG. 16 illustrates a computer system in which two pointing devices 110 and 120 and two monitors 140a and 140b are connected to one computer main body 130 for an interactive game.

In this case, the first and second pointers 141 and 142 may be displayed on each of the monitors 140a and 140b. However, in order to prevent confusion of the user, only the first pointer 141 is displayed on the first monitor 140a. In addition, only the second pointer 142 may be displayed on the second monitor 140b.

Meanwhile, as illustrated in FIG. 17, a touch screen user interface may be provided without using a pointing device such as a mouse. That is, the plurality of objects displayed on the monitor 140 are selected or moved by the movement of the user's hand in contact with the touch screen, not by the pointing device.

For example, in FIG. 17, when the user selects a watermelon-shaped icon at the top right, a watermelon image is displayed at the center of the screen as shown, and then touches a color icon at the bottom and then touches a specific portion of the watermelon image. The corresponding portion of the watermelon image can be changed to the selected color.

Although such a touch screen method is difficult to apply to a complex game, it can be very useful for a play or educational computer for an infant.

The multi-pointer also makes it easier to implement 2D or 3D graphics on a computer. For example, set the central axis of the image to be drawn while holding the pointing devices 110 and 120 one by one on both left and right hands, and grab one point with one pointing device 110, and then grab another point with the other pointing device 120, and then pull. Various variations can be made, including pushing, rotating and rotating.

In addition, when one pointing device 110 performs an operation such as selecting an icon or a menu, and the other pointing device 120 performs a graphic work, the moving distance of the pointer can be reduced, thereby improving work efficiency and being applied to the body. Reduce work stress
