Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a computer-aided learning system that uses a computer to advance a learner's learning in an interactive manner.

[Technical background of the invention] Conventionally, this type of system has been abbreviated as a CAI device, but with the recent spread of microcomputers, the computer itself that executes the learning program has changed from a large or medium-sized computer to a personal computer. They are being gradually replaced by computers.

In this CAI device using a personal computer,
Usually, a learning terminal equipped with a keyboard and a cathode ray tube display device is arranged for each learner, and in response to a request from the learner, (1) explanatory text of the content of the learning program is displayed on the display device.

■Display the study questions on the display device.

■Have learners enter answers using the keyboard.

■Evaluate the answers entered.

It is configured to repeat this process repeatedly.

[Problems with background technology] However, conventional CA using a personal computer
With the increasing density of image memory elements in I devices, image information such as graphics has become sufficient to produce visual effects, but audio information is limited to sound effects using an internal synthesizer. However, it has not yet reached the stage where learning is progressed through continuous human voices. Therefore, in learning programs such as language studies that mainly use audio, many of them add audio generation means using magnetic tape.
This method is used to advance learning. For this reason, there are problems in that the operability in proceeding with learning is poor, and the learning content is not able to fully meet the needs of learners.

[Object of the Invention] In view of the above-mentioned problems, an object of the present invention is to provide a computer-aided learning system that has excellent operability and is particularly capable of proceeding with a learning program that requires audio in a fully satisfactory manner. The purpose is

[Summary of the Invention] The present invention achieves the above object by adding an optical information reproducing device that generates at least the former of audio information and image information necessary for carrying out a learning program. .

[Embodiment of the Invention] FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 indicates a system main unit, and a central processing unit (hereinafter abbreviated as CPU) 10. A first floppy disk device (hereinafter abbreviated as FDD device) 11. which stores a learning program to be executed by the CPU 10. A second FDD device 12 that stores learning data necessary to execute the learning program. These FDD devices 11.12 are CPU
The FDD controller 13° is controlled by a control signal inputted through a control bus of LO, and is provided with an external interface 14 for transmitting information with external equipment. In general, it is equipped with an optical information reproducing device 15 that generates audio information.

Of these, the portion consisting of 10 to 14 corresponds to what is called a computer, and the optical information reproducing device 15 corresponds to what is called a compact disc player (CD player). This device 15 is a disk-shaped recording medium 1
50 is picked up by a laser beam, converted into an analog signal by a DA converter 151, and then input to a speaker 153 via an amplifier 152, thereby generating sound. Therefore, audio information corresponding to the learning program is recorded on the recording medium 150, and is transmitted to the servo circuit 155 via the interface 154 in the course of sequentially executing the learning program.
by driving and reproducing the audio information you need.
It becomes possible to perform learning accompanied by audio. in this case,
Since the recording medium 150 can be randomly accessed,
Since specific audio information can be played repeatedly or intermittently, learning can proceed effectively.

On the other hand, for the system main unit 1 configured as described above, there is a learning terminal 1 comprising a keyboard 20 for inputting answers and a cathode ray tube display device 21 for displaying learning questions, etc.
is connected to the external interface 14.

FIG. 2 is a diagram showing a recording format of audio information recorded on the recording medium 150 of the device 15, in which audio data including a frame synchronization signal, a subcoding signal, and parity check data corresponds to one display frame of the display device 21. and recorded in frames.

Among these, the frame synchronization signal is for synchronizing data in frame units, and the subcoding signals are P, Q, R, S, T, U, and V.

This indicates n-bit channel data called the W channel, and the name of the audio data is recorded in the P channel, which is used to determine the beginning or end of the audio data.

Further, as shown in FIG. 3, in the Q channel, the order of audio information in frame units, information on the division of audio information within one frame, time codes such as the recording time of audio information, etc. are recorded. Furthermore, image information is recorded in the R to W channels as necessary. Note that the information on each of these channels is composed of, for example, 8 bits in order to simplify the exchange with the CPU 10.

In the above configuration, to start learning, first set the storage medium of the FDD device that stores the learning program and learning data corresponding to the desired learning content into the FDDH devices 1 and 12, and then The recording medium 150 on which the corresponding audio information is recorded is transferred to the device 1.
Sera i~ on 5th.

Next, a command to start the learning program is inputted from the keyboard 20 to cause the CPU 10 to start executing the learning program stored in the storage medium of the FDDl 1.

When the CPU 10 reaches a stage where it is necessary to generate audio during execution of the learning program, the CPU 10 determines in which area of the recording medium 150 of the device 15 the audio information regarding the required audio exists using the P channel in the sub-coding. Search based on the recorded information of and Q channel,
Play back the audio information recording area obtained as a search result, and
The converter 151 converts the signal into an analog signal, and the speaker 153 generates audio. When P channel information is detected after a certain period of time, it is determined that the audio information has ended, and the learning program advances to the next stage.

Note that if the system main unit 1 and the learning terminal 2 are installed at the same location, the configuration shown in FIG. When connecting to the system main unit 1 via a line or the like, the speaker 153 needs to be placed on the learning terminal side. In this case, the system main unit 1 can be shared by multiple learners.

Further, the image information is reproduced from the device 15 along with the audio information,
Display g on learning terminal 2! If it is displayed in the position 21, the visual effect can be further improved.

[Effects of the Invention] As explained above, in the present invention, at least the former of the audio information and image information necessary to carry out the learning program is generated from the optical information reproducing device, so that the audio information for language learning etc. This has the effect of allowing learners to proceed with learning in a way that satisfies them without having to perform complicated operations, and further improving the reliability and evaluation of the machine-aided learning system.
