Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to an electronic learning device that can carry out various types of learning in an interactive manner with an operator using a large-capacity memory medium such as a laser memory card or a laser disc. .

<Prior Art> Conventionally, various learning devices have been used depending on the learning content. In particular, those that are based on electronic circuits and have interchangeable memory media can be used for a variety of learning purposes.

However, in the case of these conventional electronic learning devices, small-capacity semiconductor memory is used as the memory medium, and due to the memory capacity limitation, learning can only be performed according to a certain program, making it difficult to operate. The drawback was that learning could not be conducted in an interactive manner according to the instructions of the person.

<Purpose> The present invention has been made to eliminate the above-mentioned drawbacks of the conventional technology, and by using a large-capacity memory medium such as a laser memory card or laser disk, the present invention is not a one-time learning process, but an easy one for the operator. It is an object of the present invention to provide an electronic learning device capable of interactively switching learning information to be read next from a large-capacity memory medium in accordance with instructions.

<Embodiment> In FIG. 1, the MPU is a microprocessor that executes programs in memory and controls data input/output to each unit described below. ROM is a read-only memory, and an initial program loader (IPL) is stored in advance. When the power is turned on, this IPL is executed first. RAM is a random access
It is a memory that stores programs and displays read by the laser card below. The CRT is a CRT display device that displays information to the operator. CRTC is a CRT controller, and the information to be displayed is stored in the built-in video RAM.
A display signal is output to the CRT according to the contents of this video RAM. KEY is a keyboard, which the operator uses as an input device.
KBC is a keyboard controller, KEY
determines the input state of the microprocessor
Outputs the input key code in response to a request from the MPU. LCU is a laser memory card reading/writing device. As a laser memory card, one made by DREXLER TECHNOLOGY can be used, and up to 40 million bits of digital information can be stored in a card-sized one. This has two optical recording parts: the crust and the underlayer.
It is made up of layers, and records are recorded by applying a laser spot and making holes in the outer skin.When reading, information is also scanned with a laser spot and information is read by changes in the reflectance of the outer skin. LCC
is the controller of the above LCU, which outputs control signals to the above LCU so that the area designated by the microprocessor is accessed, and also sends information to be read or written to the laser memory card reading/writing device LCU. input/output.

FIG. 2 shows the information areas of the laser memory card LC by type. B is an area in which the correspondence relationship between each storage area and the stored content is recorded. For example, it records the number of the program and from which position it is recorded. B is a storage area for various programs to be described later, such as a program for displaying a menu, a program for asking questions, etc. C is a fixed data recording section, which is, for example, image information used for displaying base data for creating questions and hints. 3, 4 and 5 are flowcharts showing the operating procedure of the above system. First, as shown in FIG. 3, when the power is turned on, an initial program is loaded into the RAM from the laser memory card (a ₁ ), and then the program is executed. This causes a menu to be displayed (a ₂ ). For example, the name of the subject to be studied is displayed along with a number. When the operator specifies (inputs) a desired subject by its number, the program corresponding to that number is loaded from the laser memory card. For example, if you select the subject ``Science,'' a program for learning science will be loaded. FIG. 4 shows the processing when this loaded program is executed, and first, items are displayed (b ₁ ). This is, for example, a display requesting input of the operator's age and gender. Accordingly, if you input an item, a test program will be loaded from the laser memory card according to the content (b ₃ ).Selection of such a test program is loaded in _a4 of Figure 3. The method is determined in advance by the program. FIG. 5 shows the procedure for executing the loaded question program. first,
The question number recorded during the previous study is read (c ₁ ), and then that question number is uploaded (c ₂ ) and a new question program is loaded (c ₃ ). Questions are displayed according to this question program (c ₄ ). The operator responds with a number to answer this question (c ₅ ). If this answer is incorrect, a hint program is loaded into RAM and displayed to display a hint (c ₇ , c ₈ ). That is, it determines whether the answer is correct or not based on the displayed state and key operation state, and determines the next information to be read from the laser memory card, which is a large-capacity memory medium, based on this judge output. loads the hint program from the laser memory card to RAM. If the answer is correct, it is determined whether a predetermined amount of learning has been performed, and if the predetermined number has not been reached, the next question is asked (c ₉ →c ₂ ).
If the predetermined number has been reached, the question number at that time is newly written to the write data area (c ₉
→ _c10 ). Then, the screen returns to the original menu display.
(c ₁₀ →→a ₁ ).

<Effects> As described above, according to the present invention, it is possible to read out the next most appropriate program according to the learner's answers and instruct learning information, and learning can be done in an interactive format rather than a one-shot learning process. In addition, learners can easily see what they learned last time on the screen when learning, and they can learn efficiently without having to repeat the same learning over and over again. By sequentially reading the necessary information from the medium and storing it in the memory, and controlling the display means etc. based on that information, the memory does not need to store all the programs, but has a small capacity that can store only the necessary information. Moreover, the time required to copy information from a memory medium to a small-capacity memory can be shortened, making it possible to provide an excellent product in terms of memory capacity and time.
