Abstract

PURPOSE: A learning device for a language study and a method thereof are provided, which playbacks an audio signal stored in a memory pack automatically by recognizing an event operation for an infant to turn over a page of a book. CONSTITUTION: According to the infant learning device for language study, a body(01) playbacks a digital audio signal stored in a memory pack and read it to an infant according to received information from a terminal(02). The device comprises an infant teaching material(03) in the form of a book or a card. And the terminal is installed on the infant teaching material and recognizes page information automatically, and then transmits it over wireless to the body using an RF(Radio Frequency).

Description

Learning machine and system for language study}

The present invention relates to a language learner and a method of operating the learner, and more particularly, to a spoken infant learner such as a mother reading a book to a child. To this end, the present invention, by considering the means to determine the page on the textbook and can recognize it, by recognizing the event action that the infant handed over the book to record the audio digitally recorded in advance in the memory pack The present invention relates to a device that automatically plays back.

In general, in the case of the currently available language materials for infants (eg analog tape), the audio can be heard only when it is accompanied by artificial input, for example, key input or touch of a certain switch. . In practice, however, it is not only difficult for an infant to handle these tasks normally, but it is also inconvenient to place a device that generates audio immediately in the immediate vicinity and repeat the same operation as necessary, for example, play or stop. In addition, because the infant does not know the writing yet, without the parent's help, you can only listen unconditionally as it does not know what part of the current audio.

The present invention is derived to solve the above problems, basically, without the operation of a separate key input, such as infants in accordance with the speed at which the child is looking at the textbook, if the infant simply looking at the book and flips the book, if necessary, the operation of the micro It is an object of the present invention to provide a system that automatically recognizes the controller and automatically outputs the audio corresponding to the page currently viewed by the infant.

In addition, in order to implement the playback speed of the audio according to the learning level, the audio is stored in three stages (very slow speed, slow speed, normal speed), and a means for selecting it is provided.

The present invention, in order to achieve the above object, as shown in (Fig. 1), the main body (01) and the book that the infant reads the story to the infant by playing the digital audio stored in the memory pack according to the received information from the terminal or It has three functions: a card type infant teaching material (03) and a terminal (02) that is attached to the infant teaching material currently viewed by an infant and automatically recognizes page information and separately transmits RF using a main body. . In FIG. 1, reference numeral (04) denotes recognition of page information of an infant teaching material, and reference numeral 05 denotes RF transmission from a terminal to a main body.

In order to perform the above function, the infant teaching material 03 prints a bar code on a portion of the surface of the teaching material so as to distinguish page information, or a sticker on which the barcode is printed is attached to a portion of the teaching material surface. The form of the terminal 02 has a structure that is mechanically attached to a predetermined position of the infant teaching material so as to read the bar code printed or attached to a predetermined portion of the infant teaching material 03 and determine page information.

Such a terminal includes a page information recognition unit 12 as shown in FIG. 2 to recognize a page currently being viewed by the above method, and to inform the microcontroller 11 of this information, and the wireless transmission unit 13 is a microcomputer. By the command of the controller, key information, which is input information from the key processing unit 14 having a page information or a plurality of keys (Speed, Volume, etc., not shown separately) to the microcontroller, is transmitted to the main body (FIG. 3) (RF (Radio Frequency)). Wireless transmission is used. The battery unit 15 supplies power necessary for the terminal (FIG. 2).

The main body (FIG. 3) is a wireless receiving unit 22 for receiving an RF signal transmitted from the terminal (FIG. 2) and sending it to the microcontroller 21, and a key processing unit for processing key information input from a plurality of keys (not shown). (23), a memory pack 26 for storing digital audio, an audio processor 24 for processing the digital audio data read therein, and outputting audio to the speaker 27, a power supply unit 25 for supplying power, and each of the above parts. And a microcontroller 21 for controlling the functions from (22) to (27). The memory pack 26 has a structure that can be stored so that it can be exchanged according to various infant teaching materials. In addition, in order to implement the playback speed of the audio according to the learning level, the audio data is previously stored in the memory pack 26 as an embodiment, and three levels (very slow speed, slow speed, and general speed) are separately stored, and A selectable means, i.e., key input (playback speed selection key, not shown) is provided to select a speed suitable for the infant's level. The general speed here, for example in English, is the normal speed used by people who speak English as their native language, and the very slow speed means that English speakers do not use English as their native language, For a person who does not know a little about how to pronounce slowly. The slow speed is about halfway between the normal speed and the very slow speed.

4 is a flowchart for determining a change of a page processed by the terminal (FIG. 2). First, when the power is turned on, the variables and constants related to the page change determination are initialized (41). t is an internal timer operating inside the microcontroller, and is used to determine whether the predetermined set time T time has elapsed (42).

In the process of (42), the page information is not updated until a predetermined time (T) has elapsed, and when the predetermined time (T) has elapsed, the page information is read and chattered (43) for the reliability of the data. Thereafter, the obtained page information is stored in D1 and the internal timer t is initialized again (44). In the next step 45, the current page information D1 is compared with the past page information D2 to determine whether the page information has changed (45). If the information of D1 and the information of D2 are the same at 45, the page has not been changed, and at this time, event information (page change notification and changed page information) is not sent to the main body (FIG. 3). If the information of D1 and the information of D2 are different, the page is changed, i.e., event information (page change notification and changed page information) is transmitted when an event occurs, and after updating (46) the data of D2 to the value of D1, The process from step 42 to step 46 is repeated.

As described above, according to the present invention, when the infant simply reads the book and passes the book as needed, the microcontroller recognizes the operation without requiring a separate key input and the like. By automatically outputting the audio corresponding to the page you are viewing, the output audio is always automatically matched to the textbook that the infant is watching. To provide functionality. In addition, with the function to select the playback speed of the audio, it is possible to increase the educational effect by enabling the education according to the level.
