Description

Computer-based Integrated Multimedia Distance Learning System and Its Method

The present invention relates to a computer-based integrated multimedia distance learning system and its method constructed on the basis of a multimedia application development platform developed by itself.

The development of various approaches for distance education has been accompanied by technological advances in the means of delivering education services to education consumers (postal systems, radio / TV broadcast, cable TV, satellite and telephone network). have. This means that distance learning is more sensitive to technological advances than traditional classroom-based teaching methods. Therefore, this technical closeness indirectly suggests that distance education needs to be combined with multimedia and information and communication technology in order to be more effective than simply delivering education services to remote locations.

However, in the distance learning environment, the delivery of education services has been achieved through radio, TV, and satellite broadcasting technology from the correspondence education stage, which used the postal system to deliver text and graphic-oriented education contents using analog data representation. Through the teacher-oriented, non-interactive education phase of the single direction, the system is being developed as a interactive interactive video lecture system combining CATV, interactive TV, and satellite communication technology.

However, unlike the existing expensive video conferencing equipment and leased-line lecture system using the computer communication network as an effective educational environment, it is possible to effectively support mutual participation between professors and students. The development of an integrated multimedia learning system is becoming increasingly important.

As a result, the use of a computer to exchange character or graphic data using a communication network from the stage of use of a stand-alone for document editing and data processing mainly on non-interactive character or graphic data by digital data representation. It has evolved into the CMC (computer mediated communication) phase, with its role as an intermediary. Computer Aided Instruction (CAI) or online home-based education is one of the representative examples of using CMC technology.

However, the realization of this new learning system requires a lot of time in technology development because it should be designed in the form of computer engineering, computer communication network technology, computer-supported cooperative work (CSCW) technology and education engineering based on the multimedia application development platform. There is a problem that the user's fee is expensive as it takes a lot of money to be developed and developed.

Therefore, in the present invention, the CMC technology applies the CBM (Computer Based Multincdia) technology combined with the high speed communication network technology and the multimedia information processing technology. Unlike CMC technology, CBM technology enables real-time interaction (conversation, question and answer), so it is suitable as a foundation technology for the structure of distance learning environment using multimedia data as a medium of dialogue.

The present invention is based on a multimedia application development platform (industry) developed by itself, overcomes time and space constraints and provides a realistic educational environment between teachers and students who are geographically separated using multimedia, synchronous or asynchronous The purpose of the present invention is to provide a computer-based integrated multimedia distance learning system and a method which can easily support interactive interaction.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

1 is a network diagram of an integrated multimedia distance learning system according to the present invention, in which 11, 12, and 13 represent an integrated multimedia distance education system, and 14 represents a computer communication network.

The integrated multimedia distance learning systems 11 to 13 are combined together like a multimedia computer to form a single system, and the plurality of distance education systems are interfaced with each other through the computer communication network 14 to perform distance education using two-way communication.

Each multimedia distance education system supports the basic computer for multimedia, sound card for voice, video capture board for moving picture, hardware codec or software codec for efficient communication of such moving picture with other party, and overall operation. This requires an operating system, a network card for communication, and a main memory of 16M bytes or more. In addition, as additional equipment, a camera, a keyboard, a mouse or a graphics tablet, a speaker, and a microphone are required and basically perform the following functions. The camera takes a picture of yourself educated and sends it to the other party in real time or displays it on your own monitor. The basic input tool is a keyboard and mouse (graphic tablet). A speaker is required as a tool for sound output, and a microphone is required for voice input. In addition, since the video capture board and the sound card are determined by the design of the media server dependent on each media card, any hardware may be used.

2 is a configuration diagram of an integrated multimedia distance learning system according to the present invention, in which 21 is an operating system, 22 is a multimedia application development platform, and 23 is an integrated multimedia application.

The present invention has a structure in which a platform (a DooRae) is configured on an operating system 21 of Windows 95, and an integrated multimedia distance education application, which is an application program, is configured based on this.

Multimedia application development platform (Dule) 21 is a platform developed in-house to help the application development of integrated multimedia, the present invention was also made using this structure, the infrastructure has an operating system, communication agent, cooperative function .

The structure of the multimedia application development platform (dules) 21 is composed of functions 24 for mutual cooperation and application sharing 25, and the detailed structure of functions 24 for mutual cooperation is an initial agent. (26), mutual cooperation support (27), intelligent agent (28), communication and transport protocol (Communication and transport Protocol) (29), and Media Control Agent (Media Control Agent) (30).

Looking at the operation of each component in detail as follows.

The initial agent 26 is composed of several subclass modules. This subclass module provides the basic services for the application while the submodules combine the basic services into one application. The initial agent 26 serves to start and end the video window, the whiteboard and the voice mode. The whiteboard provides a variety of graphic / text tools (freehand lines, coloring, straight lines, boxes, wintext, patterns) that can be used for collaborative learning or distance learning. The result of using the various tools used here is immediately displayed not only in own window but also in the participant's window, so that the blackboard in the group education can be replaced. In addition, the whiteboard can use a pre-made learning, and in the case of a test situation can deliver the same problem to multiple users at the same time.

Cooperative support 27 includes Session Management Agent (SEMA) and Access Control and Concurrency Control.

SEMA controls the access of the entire session (any application software developed in the context of video communication, voice communication, distance learning, telecommunications, gaming and multimedia application development platforms). Session control can grant or restrict access to an entire session. SEMA monitors the beginning and end of sessions, and controls / manages participants' participation and visit (invited lecturer) decision making, late commers and other sessions. This module consists of Local Session Manager (LSM) and Global Session Manager (GSM) to manage multiple classes. Even if several sessions are open at the same time, each LSM only needs to manage its own session. GSM ensures independent communication of multiple sessions and manages LSMs so that they do not collide with each other. In addition, the LSM can reduce the traffic of the network by engaging the perceptors in the session and by disconnecting the communication with those who leave early.

The Access Control Agent (ACCA) determines who currently has the right to speak (controlling the right to speak) and, if so requested, determines the current user manager and resource distribution policy. Speaking control methods include teacher intervention mode, brain storming, priority mode, token-passing, and timeout. In the multimedia application development platform according to the present invention, it is initially set as the teacher intervention mode, and the mode can be changed during the lecture.

Concurrency control inevitably occurs in a distributed multimedia environment where multiple users collaborate simultaneously. When several participants on the network enter commands, it cannot be processed in order of arrival because of the variability of the network. Concurrency control is to solve this problem. Concurrency problems occur in a distributed environment when several users simultaneously request the same media, because multiple participants use different computers. This problem should be answered to the extent that the participant can tolerate delayed input results. We attempted to solve this command sequencing problem using the concept of a centralized server and a distributed synchronized clock method. ACCA maintains a history of interchangeable instruction sequences to ensure concurrency control and instruction ordering. Since all input commands are passed to the ordering server with the time information at the moment the command occurs, the ordering server can process them according to the order of the commands. The system that issued the command outputs the result to the monitor as soon as the command is issued to reduce the tedious time, and if the rule is abducted, the system outputs it again, but the probability of occurrence of this result is very suitable for use in distributed multimedia environments. Do.

The intelligent agent 28 is an intelligent agent designed to support interactions between dissimilar computers, and is essential for delivering media data and informing a remote participant of awareness. Heterogeneous data exchange is a difficult problem but very important. We modify the TCP / IP and UDP / IP packets to solve this problem.

The message of the shared object uses the object data as it is on the same computer. However, the heterogeneous computer converts the encoded format of the media data to accommodate the heterogeneous computer according to the data format. In order to solve the problem of awareness that informs the cooperation status, the intelligent agent has an event message table, which can be converted into a message on the receiving side and transmitted. The processor reorders the byte order mismatch, after which the event message or shared media data is sent to the computer by the intelligent agent.

The CRoss Platform Communication Agent (CRPA) in the Communication and Transport Protocol (29) is responsible for communicating between participant computers in a distributed environment. And, the communication agent (CRPA) is used by other agents such as COPA, ACCA to achieve their purpose. CRPA connects the network for collaborative work, measures the load on the network to determine the transmission rate, and supports quality of service (QoS). The protocol used was to add control data of multimedia application development platform (Dule) to packet format of TCP / IP and UDP / IP. Additional control data keeps the media data in order. Even if several sessions are opened at the same time, the CRPA protocol has its own session number so that it does not make a mistake in sending data to other sessions. The transmitter consists of a traffic controller and a packet generator.

The traffic controller determines the bit rate, which is the basic transmission rate, according to the type of network. This function is to cope effectively when the network environment changes to the high-speed information network or other network in the future. That is, it flexibly responds to the type of network. Other factors for determining the bit rate check the current network usage, delay jitter, time stepping, and changes in data values. Global Time keeps clocks synchronized with each other by delivering their time information to each other when a multimedia application development platform (Dure) application first starts, when a new session is opened, and when a new participant occurs.

The packet generator is responsible for adding the necessary information in the multimedia application development platform (Dure). That is, a complete packet is created by adding session number, event format, sequence number, time stepping, and special data required by the application to the transport packet. This packet is forwarded to the sending subsystem.

The media control agent 30 manages hardware resources. It also controls the efficient allocation and termination of limited media resources (devices), allowing for efficient resource utilization and sharing of media resources among remote users.

Application program sharing (25) may be divided into two structures according to the location of the application, the location of the program for application sharing, and the operation method. The first is the centralized structure, where only one application exists among all the sharers, and the central server manages all input, processing and output. The second method is a duplicate structure, in which an application program is copied to participants and only the data and inputs generated during sharing are executed.

The replica type has the advantage of reducing the communication load. However, all participants must have an application, and it is difficult to order the instructions that occur in each participant. Furthermore, if the application program is in the form of multimedia data, command transmission is negligible compared to the data transfer rate. To solve this problem, we realized centralized application sharing. Application sharing uses the Windows hooking method in which the application receives an intermediate process in the process of using the message-based process communication method. Windows hooking completely intercepts events such as the keyboard, mouse, system, and bitmaps. The intercepted events are delivered by the Application Program Agnet to its own application, and the results are sent to its monitor and sharer's application agent. The remote sharer delivers the events of its input devices to the application sharing agent on the server side through the application sharing agent and acts as if it had its own application (VAP: Vitrual Application Program).

3 is a detailed configuration diagram of the integrated multimedia distance learning application according to the present invention, in which 31 is a user interface, 32 is a lecture environment establishment scenario, 33 is a lecture environment, 34 is a test / evaluation environment, 35 is a control window, and 36 is Denotes a personal window, 37 denotes an image window, 38 denotes a co-learning window, and 39 denotes various tool boxes.

The distance learning system according to the present invention has been designed and realized in a multimedia application development platform environment. The multimedia application development platform (Dure) has three types of education: self-learning (learning by the guidance of the provided CAI software), distance learning (direct teacher teaching), and collaborative learning (discussion learning). In collaborative learning mode, one or more experts can be invited as invited lecturers separately from the teacher.

The user interface 31 is divided into an interface in the form of a tool window collected by the user himself to use various preference modes between the teacher and the students and used by the user's preference. The former is used to set the use and format of audio, video and whiteboard work. The latter is used as a tool for teacher or student taking and answering questions. Is being provided. In addition, depending on the features selected by the lecture participants, the help function is provided to remind the meaning of the recently selected tools. In order to provide an easy and simple interface for the users of this distance education, the menu method and most functions are iconized. In addition, the location of the tool window is divided by function, and it is designed to help the assistant in charge when using the helper function to solve the difficult situation encountered during the lecture. In addition, there is less confusion in using separate windows by function. Function windows include control windows, video conferencing windows, whiteboards, personal windows, and toolboxes. In particular, the classroom environment, test environment, oral test environment can be selected and implemented according to the educational purpose, and appropriate interface is provided accordingly. In the case of collaborative learning, there is a pencil with a unique color for each use of the whiteboard to distinguish users.

The lecture environment 33 uses a control window 35, a personal window 36, an image window 37, a co-learning control window (White board) 38, and various tool boxes 39. Through these windows, various information related to the progress of the lecture is displayed and used for inputting the user's response.

The purpose of these windows is divided into functions as follows.

The control window 35 may identify a participant list (attendance, absence display), lecture date, lecture title, and the name of the teacher who opened the query. In addition, the user's environment required for the lecture, that is, voice mode ON / OFF function can be used to set whether or not to use audio resources during the learning process, and the video mode ON / OFF (ON / OFF) It may be used to determine whether or not to use the image window 37, and may be appropriately determined according to the data transmission speed of these networks. You can also select the access control mode. Access control is used to control the voice for question and answer. The control method is mediation, token passing, etc., but in the case of distance lecture, the mediation method by the teacher is set as the initial value. have. The participant list is automatically deleted at the student's request to leave when a student withdraws.

The personal window 36 is located only on the teacher's computer and is used to refer to necessary materials during the lecture or to perform a similar purpose.

The video window 37 is a space in which a lecture participant can be viewed as a video and is an important space used for face-to-face effects between a teacher and a student. Since each video window can be set independently for each participant, it is designed to check the video of all participants in the lecture. In the picture window, each name for identifying a participant is displayed. The video used here uses 256 colors, and the image size and bit rate are determined by the use of a software codec. The former has a transmission rate of about 12 frames per second in QCIF (176 * 144) size, and the latter can transmit 27 frames per second in full screen size. Of course, the size and position radius of the image window can be adjusted to the user's convenience.

The co-learning control window (whiteboard) 38 is a collaborative window necessary for conducting learning in the form of mutual participation. In the remote lecture, the co-learning control window (whiteboard) 38 is used for the purpose of transmitting a lecture syllabus of a teacher and receiving a question from a student. Tutoring or discussion-based learning is used for collaboration, discussion, and mutual participation between teachers and students. In addition, when the whiteboard function is used in conjunction with the application sharing technology, commercially available original document editors and authoring tools can be utilized as authoring tools of the mutual participation environment of the distance learning multimedia application development platform (Dure) without modification. In addition, the whiteboard supports the writing and display functions using a graphic tablet and mouse, and the typing function using a keyboard. It is possible to check the contents of each question by distinguishing the inputs from different participants with different colors.

The test / evaluation environment (34) allows students to take a test with a test question written in a hypermedia authoring tool. The test results are sent to the teacher's test / evaluation window as soon as the correct answers are entered, and the correct and incorrect answers are color-coded. Test scores, grades and distributions are immediately calculated and displayed in the professor's window. The student's answer sheet is kept in a file and used as a student's learning history management and individual guidance materials. In other words, oral and online simultaneous written examinations are used as the evaluation method. The process of the online concurrent test is as follows. In other words, the test questions written by the authoring tool of the multimedia application development platform are simultaneously sent to the students, and the students who receive the test papers press the start buttons to start the test. Then, after the exam period has elapsed, the student's answer will be sent to the teacher and no further corrections will be allowed. At the end of the semester, grades can be graded and compared to the teacher's correct answer, which is sent from the student side.

The procedure of the Lecture Environment Creation Scenario 32 is as follows.

1) The teacher prepares a new syllabus, teaching plan, and teaching aid, or registers the teaching plan and teaching aid database of the distance learning multimedia application development platform (Dure).

2) Start the daemon on a different system than the one being trained (connected to the LAN).

3) After entering the course name, the teacher sends a class invitation message to the students who are already enrolled in the course and the students who will be newly enrolled.

4) Teachers and students connect mini daemons. The video and audio windows appear on the teacher's system and are available for use.

5) Students who have been invited by the teacher enter their name and student number and decide whether or not to participate in the lecture.

6) A student tool bar will appear on the computer of the students participating in the class, including the name of the class, the name of the teacher, and the tools to be used in the class.

7) The teacher can check the individual's appearance through the video window of the student's attendance. After the preparation for the class, including attendance checks, is confirmed, the teacher sends the materials for the class to the student using the co-learning control window (whiteboard) and the learning tool window for teacher and student interaction. Proceed with lecture.

8) During the lecture, the teacher selects a query as the teacher intervention method to handle the simultaneous request of questions from multiple students. The selected inquirer is given a voice by the teacher, and then the question is queried through the microphone, and at the same time, the inquirer can be seen through the image window.

9) After a certain amount of time has passed for the teacher, the lecture will end with a signal for ending the course, and attendance records will be stored in the student management database.

4A and 4B are an overall flowchart of the integrated multimedia distance learning method according to the present invention.

First, register the learning syllabus database and supplementary materials in advance (41), install (start up) the daemons before starting distance learning (42), and set up the teacher and student system for distance learning. Connect with the mini daemon (43). As a result, a control window and a personal window (video window with self-moisture) appear on the teacher and student systems, and a video window (showing the other party) and an audio window are created on the teacher side system.

After that, the teacher enters the attendance list to participate in the education (44), the teacher sends a message to call the attendance (45). A message box pops up on the student's system to register attendance (46). If you do not register in the message box is determined not to respond to the teacher's invitation to process the absence (47). If registered in the message box, it is determined that the teacher's invitation has been attended (48).

After checking the attendees on the list (49), the teacher sends a message (50) to the students (the subject) to be educated. After that, the lecture (education) is started (51).

A video window and an audio window are created in the attended student's system so that they can be educated while watching the other's face and listening to their voice (52). Select an application share or whiteboard from the training tools (53).

If the application share (power point, Hangul, MS-WORD, other perceptual tools) is selected (54), the application share is executed (55).

If the whiteboard is selected without selecting the application share, the whiteboard (blackboard) is used for training (57).

If there is a change in the educational tool (58), and if there is a change in the educational tool, the process shifts to the process of selecting the educational tool (53), and if there is no change in the educational tool, it is checked whether there is a remark (question).

If there is a remark (student question), the teacher judges whether or not to speak (60), and if the teacher accepts the remark (student question), the student speaks (61).

If there is no remark (student question), the teacher does not receive a remark (student question), or the student remarks, the teacher checks whether the student has a question (62).

If there is a teacher's question, the student answers (62) and then checks whether or not to take the test (64). If there is no teacher's question, checks whether or not to take the test (64).

In the case of the test, students complete and submit the answer sheet (65) to confirm that they will complete the test and complete the education (66). If the training is not completed, the process transitions to the process of selecting an educational tool (53) to continue the training, and the training ends in the training mode.

5 is a detailed flowchart of an application sharing process according to the present invention, and determines what to do with application sharing.

First, determine whether it is Hangul Hangul (51), if it is Hangah Hangul, run Hangah Hangul (52). If it is not Hangul Hangul, MS-WORD is determined (53). MS-WORD) (54), MS-WORD determines whether it is PowerPoint (55) or PowerPoint if it is PowerPoint (56), or other authoring tool if it is not PowerPoint (57).

6 is a detailed flowchart of a teacher intervention mode processing process according to the present invention.

If there is a speech, it is decided whether to give a speech in the order of speech by selecting the teacher intervention mode or to speak as the teacher assigns (61, 62). If the student's comments are ignored (63).

Then, check whether there is a talk stop time (65) If there is no stop time, continue speaking until the end of the talk (66), if there is a stop time, continue speaking until the stop time (67) Exit mediation mode.

7 is a detailed flowchart of a student's answer sheet preparation process according to the present invention.

When a teacher asks a question through application sharing or whiteboard (71), students receive the question and write an answer (72).

The test time is checked (73) and when the test time is over, the test is terminated and the answer cannot be made (74). If it is not the end time of the test, keep checking the test time.

After that, check the positive and negative (O / X) in the answers in the batch test site (75) and the score is calculated and the score is recorded in the teacher file (76).

The present invention as described above can support the interaction between the teacher and the student using the integrated multimedia, at the same time can be learned between a large number of professors and students, lectures can be invited to other experts in the course of cooperation. In addition, the present invention can be used not only for the discussion-based remote lecture, but also for remote examination, oral examination, distance learning, and learning management, and in particular, using the application sharing function, the existing CAI (Computer Assisted Instruction) program or course developed for a single user. The software can be utilized without modification, and since the user's location is not restricted, the temporal and spatial flexibility is high. In addition, despite the high temporal / spatial flexibility, high interactivity and extensibility, it is less expensive than remote video education, and it is possible to open multiple lectures that cannot be supported by other distance education systems.
