Apparatus for Studying using Stylus Pen of Electrostatic Induction}

The present invention relates to a learning apparatus using an electrostatic induction type electronic pen, and more particularly, to provide a learning textbook including various functions (eg, English sentence reading, spell reading, listening, speaking, games, etc.) By using the induction method to recognize the position where the electronic pen is in contact (that is, the coordinates of the picture indicating the function), the learner (eg, infant, child, etc.) is interested in performing the function corresponding to the recognized coordinate. The present invention relates to a learning apparatus using an electrostatic induction type electronic pen that can easily learn the contents of a learning textbook.

In general, it is well known that children are superior in learning ability including language acquisition ability. In particular, in early childhood, 80% of the brain is completed before the age of three, and a good music to give children a good concentration, memory and learning effects have been reported. As such, early education is important due to the theory that it has great learning ability in childhood, and in response to this, foreign language education, which was previously taught in middle school or above, has recently begun in elementary school, and furthermore, in kindergarten or preschool. Even young children are teaching foreign languages.

In the age of globalization, the importance of early education in foreign languages (especially English) is rapidly emerging. Therefore, it is necessary to teach English so that our children, who will be the leaders of the 21st century, can quickly receive and cope with new information. The most appropriate age for language acquisition is the 13-year-old who has a cognitive age, and learns 80% of the words used throughout his life at this time, and for children, the Language Acquisition Device (LAD). In the cerebrum, scholars claim that the LAD begins to develop from 1.5 years of age and is most active between the ages of 6, and gradually degenerates after 13 years of age and disappears as an adult. Therefore, it is advisable to teach English language education at a critical age, taking into account the child's abilities, personality and personality. The starting point for learning a language is to listen to its language and to understand its meaning, so that you need to develop the ability to distinguish between the small differences between voices in order to speak English correctly and effectively. In addition, the most important thing in learning a foreign language is that it is effective to teach listening, speaking, reading and writing in an interesting way. It should be borne in mind that constant effort and repetition is essential in daily life, not in the morning.

In recent years, in elementary English education, unlike traditional English classes where teachers provide knowledge of English and students usually memorize, student-centered play, games, songs and chants, painting, role-playing, storytelling, and research activities Classes are taught through various kinds of activities, such as problem solving using surveys and information gaps. Accordingly, a variety of English teaching materials for infants are being developed, and teaching materials that can induce interest to children (eg, English fairy tales, English nursery rhymes, video English education through play, etc.) are gaining popularity.

However, the existing English textbooks do not reflect the intentions of the learners, but the main ones are fragments that reflect only the intentions of the producers. For example, video English education through play may induce a temporary interest in children, but may not induce direct experience of children, and may not provide listening, speaking, and reading evenly. In addition, English-language education through the Internet, which is popular these days, has been well received for systematic English education by various contents, but it is difficult to approach children who are not good at computers because they use a computer that they are not familiar with. It is a method and can be used only with the help of a parent or someone who is familiar with computers. In addition, the English learning device by the e-book reflecting the intention of the learner is being released, but it does not yet meet the needs of the learners. English learning devices by e-books have a variety of problems such as the content is not enough to meet the needs of learners, the need is newly purchased, only simple functions are provided or the sound quality is degraded.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the first object of the present invention is to create a variety of content that can induce the learner's interest and become a learner-oriented foreign language education (eg, listening , Speech, reading, play, etc.) and to provide a learning device using the electrostatic induction electronic pen to maximize the learning effect by allowing the learner to select the desired content by using the electronic pen.

The second object of the present invention is to detect the coordinates corresponding to the pressing operation of the electronic pen through the electrostatic induction method to perform the function of the coordinates, to induce young learners to learn by themselves, by the pronunciation of the locals The present invention provides a learning device using an electrostatic induction type electronic pen that maximizes the effect of learning a foreign language based on practical learning, and makes it easy to get acquainted with a foreign language through a fun game that can cause interest in a foreign language.

The third object of the present invention is to extend the contents of the learning textbook by downloading a variety of content execution code to perform the function of the electronic book using a memory pack or USB port electronics of the electrostatic induction method that can acquire a variety of learning content To provide a learning device using a pen.

In addition, prior to executing the learning apparatus, it is assumed that the memory pack containing the executable code of the electronic book is inserted into the memory socket, or the contents containing the executable code of the electronic book are downloaded and stored in the flash memory.

First, the microcomputer receives the door open / close detection signal applied from the cover switch unit to determine whether the cover of the learning apparatus is opened (S510). If it is determined that the learning apparatus is not opened, the microcomputer determines whether the learner has operated the MP3 player (S520). If the learner does not operate the MP3 player, the process proceeds to the step S510 and waits for the learner's operation instruction. If the learner has operated the MP3 player, after executing the selected function, the process returns to step S510 to maintain the standby mode. Function execution of the MP3 player is well known to those skilled in the art and thus will not be described in detail here.

If it is determined in step S510 that the learning apparatus is open, the microcomputer determines whether the e-book is correctly positioned at the designated location (S540). The placement of the e-book can be identified by the e-book detection signal applied from the e-book sensor, and the e-book sensor must recognize the code number of the e-book only when it is placed in the correct position of the tablet.

For example, a serial number may be described in an electronic book, and when the electronic book sensor unit includes four optical sensors, 16 types of electronic books may be identified. The microcomputer reads the serial number of the electronic book based on the bit string applied from the electronic book sensor. Therefore, the microcomputer waits to execute the function code (ie, script) of the corresponding electronic book stored in the memory pack or flash memory.

Next, the microcomputer determines whether the learner has specified a page to be executed (S560). Before executing various functions of the e-book, the learner should designate the corresponding page using a stylus pen. The page can be specified by pressing the 'GO' menu on the bottom left of the e-book with the stylus pen. When the learner touches the stylus pen on the 'GO' menu, an electrical signal corresponding to the 'GO' menu is generated by interaction between the stylus pen and the tablet, and is decoded as a coordinate value by the coordinate detector and applied to the microcomputer. . The microcomputer recognizes that the menu touched by the learner is the 'GO' menu by reading the coordinates. If it is determined in step S560 that the learner does not designate a page, the process proceeds to step S550 and waits for the designation of the page by the learner. it, Spell it, Listen & Chant, Song & Chant, Game, Phonics, Stop]. Coordinate recognition of the execution menu of the microcomputer is the same as the method of recognizing the 'GO' menu and thus will not be described in detail.

As a result of the determination in step S570, if the learner does not select the execution menu, the process proceeds to step S560 and waits for the learner to select the execution menu, and when the learner selects the execution menu, the function corresponding to the selected menu is executed. (S580). The function description of the execution menu will be described later in detail with reference to FIG. 6.

6 is an exemplary diagram of an electronic book according to the present invention, and describes an operation relationship according to the function of the electronic book with reference to the exemplary diagram. Here, it is assumed that the electronic book is correctly disposed on the left and right tablets 405 and 415 of the present learning apparatus. In addition, it is assumed that contents for executing all the functions of the electronic book shown in FIG. 6 are stored in a flash memory or a memory pack.

Is output. For example, when the learner selects the read menu 620 and selects the tom face 705 drawn next to the sentence, the microcomputer recognizes the coordinate value of the tom face and executes the corresponding script. That is, a voice of 'Hi' is output through the speaker. Similarly, selecting the witch face 710 below, 'Hi! Tommy! Are you sleepy? 'Is output through the speaker. In addition, when the learner selects a random picture of the e-book, the words and onomatopoes of the picture are output. For example, when a learner selects a fire truck picture 715, a fire truck sound is output, and when a broom 720 is selected, a sound used as a broom is output. Here, when a word and an onomatopoe are input at the same time, the word comes out first, and then the onomatopia are automatically output.

When a learner contacts the ABC-shaped spell reading menu 630 with a stylus pen and touches a desired word with a stylus pen, the learner spells the word. For example, if the learner selects the spell reading menu 630 and selects Tommy, the pronunciation of each spell constituting the word ('T', 'O', 'M', 'M', 'Y') This is output one by one.

When the learner touches the blackboard-shaped listening and speaking menu 640 with the stylus pen, and touches the desired sentence with the stylus pen, the machine sound of the sentence is output first, and the sentence is once again after a certain time (for example, 7 seconds). Output and record the learner's voice. Then, by outputting the recorded learner's voice, the learner can determine the accuracy of the pronunciation by comparing the machine sound and his own voice.

When the learner contacts the sheet music or drum-shaped song and chant menu 650 with a stylus pen, the specified song is repeatedly outputted a predetermined number of times. In other words, the song and chant menu is a menu for learning English words using songs.

When the learner touches the dice-shaped game menu 660 with a stylus pen, the designated questions appear in order and indicate whether the answer is correct according to the learner's selection. For example, if the learner selects the game menu 660, 'My name starts with the letter D. I am on the bed. I say "Roar." Print the question Who am I ?, and when the learner selects a dinosaur picture with a stylus pen, enter 'Dinosaur. Yes. You are right. I am adinosaur, and press something else. No, You are wrong '. That is, the game menu is a menu that induces the learner's interest through the game.

When a learner contacts the pronunciation menu 670 having a [æ] shape with a stylus pen and selects a desired word, the pronunciation of the word is output. That is, the pronunciation menu 670 is a menu that allows the learner to correct the pronunciation by listening to the correct local pronunciation of the word.

When the learner touches the stop menu 680 with the stylus pen, all the voices being played are stopped and the function being executed is initialized. Of course, if the stop menu 680 is selected and another execution menu is selected, the menu can be processed again.

If the learner wants to study the next page, turn the page, touch the 'GO' menu of the page with a stylus pen, and select the above menu.
