Description

[0001] NFC BLOCK AND OPERATING METHOD USING THE SAME [0002]

In the following embodiments, a simple short-distance signal source having no power such as an NFC tag or an RFID tag is provided on a block or a sticker, and a plurality of blocks or stickers are arranged in various spaces by a user. The NFC tag is read and the arrangement on the space, in particular the NFC tag, is read so that the computer can be distinguished according to the read order.

Recently, it is becoming a big trend that it is decided that education of programming for children is included in the public education process of various countries. Especially for children, it is very popular to draw a basic programming block in software such as scratch (scratch.mit.edu), and to graphically program it. In particular, such block programming has been a long-standing research or product for attaching hand-held real blocks (Tangible Programming Bricks) (Tangible and graphical tools for introductory programming).

It is obvious that it is variously applied to block programming, puzzle piece fitting, rubik cube, board game, lEGO, etc., by tightening hand-held blocks or changing their relative positions.

The conventional mouse has a real computer having an actual circuit in a block and electrically connected to the connection part by an electrical connector so as to grasp the state of fastening of a plurality of blocks by themselves through a circuit inside the block, The computer analyzes the image of the block by photographing the block, and the computer then recognizes the order of the block, so that the computer sends the output to the screen, turns on the LED or moves the robot.

When a circuit is built in a block, it is practically impossible to commercialize the circuit because it is very difficult to connect a sufficient number of blocks because the cost is greatly increased, a fault frequently occurs in a connector portion, and a connector can not cope with a large weight.

When shooting a block with a camera, the camera must be far enough to hold all the blocks that are fastened, and because all of them are in the imaging area, it is difficult to show the role of each block or the situation when each block is executed have. In addition, since computers need to perform image recognition algorithms, high-end computers are required.

In the present invention, a simple local signal source (hereinafter referred to as NFC) having no power source such as an NFC tag or an RFID tag is provided in each block, a plurality of blocks are arranged in various spaces by users, The NFC tag is read and the arrangement on the space, in particular the NFC tag, is read so that the computer can be distinguished according to the read order. At this time, it is possible to record in the NFC tag having a distinguished ID in each of the divided blocks, and to know which block has been read when the computer reads the NFC reader.

Each time an NFC tag is read, the computer can respond to commands such as outputting the output to the screen, turning on the LED or moving the robot, reading all the necessary NFC tags, identifying their IDs and the order in which they are read, It may react accordingly. In particular, when the computer is in a mode where only the function of each block is informed, the NFC tag is about the sounding operation. When the computer reads only the NFC, it makes a simple sound, and the NFC tag moves the robot by a unit distance If you read the NFC only, you can let the computer understand the function of each block by outputting the robot moving the unit distance. However, when the user sets the mode to start each block one by one starting at a specific starting position of the program and reads the blocks sequentially in close proximity to the nfc reader, it is necessary to step-over each instruction in the debugging mode of the actual program development environment As you can see, every time you print an nfc tag in each block, you can run the nfc command and change the program's status to show the output. In this case, the position of the next command to be executed depends on the state of the program, such as the repetition of programming ('* repeated times' of Scratch) or conditional branching ('if *' of Scatch) Sometimes you need to jump to a defined location without including repeated branches or repeating statements sequentially. In this case, the computer informs the user of the next command to be executed according to the state of the program, that is, the NFC block to be next shot, through the computer screen, and if the user does not take the nfc of the predetermined block to the next position I can give directions. Unlike the case where the user specifies one command by nfc, the nfc block is moved by the user and sequentially read as many times as necessary and stored in the computer. The computer further stores a plurality of command programs stored by the user in the command block So that it can be performed without taking a picture.

The block placed by the user on the space may be placed at a position designated by the user simply by gravity or friction force, but may be fastened to each other through mechanical irregularities like conventional legos or puzzle pieces, and may be fixed like a refrigerator magnet A magnet or a ferromagnetic material may be provided and fixed by magnetic force, or may be provided with a chemical substance that can be easily attached to a light material such as a sticker or the like. Also, blocks having nfc may be fastened to each other to fix relative positions, such as fastening by unevenness between lego blocks having nfc, and relatively small nfc blocks may be fixed to a large background frame, May be fixed. For example, a large number of nfc blocks having a refrigerator magnet on a wide plate can be fixed with a magnetic force to maintain a relative position between the nfc blocks.

A method of reading a block having a plurality of NFCs is a method of moving an NFC reader such as a smart phone to a position close to each block, There may be a way to read in close proximity.

In the present invention, a simple near-field signal source having no power source such as an NFC tag or an RFID tag is provided in each block, and a plurality of blocks are arranged in various spatial arrangements by users. Then, NFC tags In order to allow computers to be distinguished according to the arrangement in the space, in particular the order in which the NFC tags are read. In this way, a computer that reads blocks arranged in a wide space by users at a low cost can implement the programming according to the blocks on an output screen or a robot, applies the mathematical problem solving education through block arrangement, When an NFC block is made into a puzzle piece shape and an NFC block is read by a reader, the hint related to the puzzle matching is displayed on the computer, Various interactions are possible. In addition, when an NFC tag is inserted into each component such as a prefabricated toys assembled by a user and assembled by the user, and each component is read by an NFC reader, it is determined which part of the finished product corresponds to which part, How to assemble with other parts to be assembled, and how to assemble them with moving pictures and sounds, so that the user can easily assemble and understand the whole configuration.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. However, the scope of the patent application is not limited or limited by these embodiments. Like reference symbols in the drawings denote like elements.

FIG. 1 is a block diagram of an NFC block including numerals, mathematical operators, parentheses, and NFC tags denoting parentheses. Numerical expressions are expressed in columns and then sequentially read by NFC readers. This is an example of a computer output.

In Figure 1, children use mathematics (11), arithmetic operators (12), tokens such as equal sign (14) (+ - x / = <>) and parentheses (13) (1) &lt; / RTI &gt; Each number and symbol is printed on the surface of the nfc block. In the nfc tag (2) in the block, an ID indicating each number and symbol is stored. As a result, the nfc reader corresponding to the whole expression (3) If you read to the right sequentially, the tokens of the whole formula (3) are input to the smartphone through the nfc reader on the smartphone. A computer such as a smart phone interprets the input of this token string as Equation (3), and can notify the user whether the formula is correct or not by sound, moving picture, and the like.

In FIG. 1, the tag is simply displayed on the plane at the same height from left to right. However, in the case of a mathematical expression, a logical expression, or a language, each expression is simply a flat number, But it has a recursive BNF or tree structure such that an expression or a phrase can be included in a place corresponding to an operand (number or word) . It is important to let learners learn according to this structure. Even if the computer receives the nfc block column, which means each number or character on the same level, the lexing and parsing of the conventional compiler is performed according to the priorities and parentheses according to the nature of each operator, that is, multiplication or addition. (lexing and parsing) techniques can be used to find structures using conventional techniques and computers. However, for training, it is often desirable to arrange the nfc blocks so that they show the actual tree structure rather than strings of the same height.

FIGS. 2A and 2B are examples of the expression of FIG. 1 expressed by a structural formula based on a plane or a height of a block.

FIG. 2A is a two-dimensional array of the one-dimensional block sequences of FIG. 1 on the x- and y-axis planes according to the nature of the expression. An nfc block (1 ') indicating that the expression (15: exp or expression) that develops its own value in the downward direction is developed, not a simple number in the operand but a function of itself as a numeric operand, ) Is inserted, and an expression consisting of an nfc block corresponding to a plurality of operands and an operator is developed in a tree structure below the block. In the example of FIG. 2A, all the nfc blocks are attached to the backplane 4, but it is also apparent that the nfc blocks can be fastened together and fixed.

FIG. 2B is an example in which a plurality of nfc blocks can be recursively stacked on an nfc block such that the structure is shown on the xz plane instead of the xy plane. At this time, if the expression becomes complicated, it is necessary to place a plurality of operators and an expression, which is a column of the nfc block corresponding to the operand, in a single operand position. As shown in FIG. 2B, in order to express the expression of a plurality of nfc blocks corresponding to this one operand, it can be one operand in the original operand position, and a plurality of An expression (15) (exp or epxpression) for displaying the expression on the side of the user can be inserted into the block (1 '), and the expression (3') corresponding to the expression The bottom of the nfc block column that represents multiple tokens can be concatenated. In addition, one equation block (1 ') is divided into an nfc block indicating the start of the equation and an nfc block indicating the end, and the lower surface of the nfc block column corresponding to the formula is connected to the upper surface of the start and end nfc blocks. And the nfc tag, which means the start and end of the equation, can be placed in another part of the block top surface, which means the start and end of the equation. As the fastening surfaces to be fastened between the blocks, it is possible to use the same unevenness as the legos, the velcro, the magnet, the ferromagnetic body, the adhesive, the sucktion cup, and the like.

If the goal is to visually show the structure of the expression etc. to the user without having to enter the contents of the blocks accumulated by the user in the computer such as smartphone, the nfc tag need not be included in any block such as operator, operand, or expression block .

In addition, when the number of tokens increases due to the long contents to be displayed by numbers or letters, it is not necessary to concatenate the blocks corresponding to tokens such as alphabet or digit one by one, You can write (or write and delete) tokens directly. It can also electronically record NFC tags using the user's writing on the smartphone's touch screen, keyboard, and NFC. In addition, the user writes the contents written on the surface of the block with a camera of a computer such as a smart phone, stores it with the NFC ID of the block, and can refer to it in the computer software in the future. For this purpose, when the NFC tag of the block is detected by the NFC reader of the computer, the computer can preconfigure the software of the smartphone so that the camera automatically shoots the camera. The photographed contents can be stored in the computer as an image associated with the NFC id, Computer vision, and so on, and can store and use various types of information such as text. If it is difficult to capture the contents on the same side as the nfc reader such as the position of the nfc reader such as the smart phone and the direction of the camera, attach the mirror on the front of the camera, and the content on the same side as the nfc As shown in FIG.

Figures 1, 2a, and 2b show an example of mathematical learning, but can be used not only in mathematics but also in music, language, and the like. In the case of music, nfc tags are attached to paper with musical notes that correspond to the pitches and lengths of the notes, which are attached to the backdrop with glue. Since there are so many different types of paper for every tone height and all note lengths, after the user visually displays the tone height and length on the surface of the paper with nfc as a physical writing or pasting, 1) After the surface of the paper was photographed with the camera of the phone, the images photographed by the computer vision were analyzed to determine the height and length of the visual marks on the paper, and the height of the judged musical notes And length information to the NFC tag, or 1) the user inputs the note information such as the contents written by the user separately into the smartphone through the touch screen or the keyboard, and writes this information on the paper using the NFC writing function of the smartphone You can write to the mounted NFC tag.

In the case of language education, since the language itself has a recursive tree structure such as BNF, effective education is possible by using blocks similar to those described with respect to the tree structure expression in FIGS. 2A and 2B. For example, if an operand or expression corresponding to an adverb is entered in the place where an operand is to be inserted according to the grammar type, the computer sequentially scans the NFC tags mounted on the blocks, In addition to pointing out that an adjective has been entered, you can show the grammar explanation on the computer screen with audio-visual animation.

The NFC blocks shown in FIGS. 1, 2A, and 2B and their concatenation, reading out sequentially through the NFC reader, reflecting the structures in the computer, and reflecting the structure of the formula and grammar in the structure of the block, The NFC tags are sequentially read from the computer, and the program corresponding to the physically constructed block can be read into the space inside the computer and the program can be executed. The result of executing the program can be displayed through a software object output only to the display device of the computer, or the output can be expressed by performing an actual robot or the like.

In the "if * of programming"~; Or "-;" statement is displayed as a single block in a visual programming software such as a scratch, but in the case of a block representing a language structure having several arguments corresponding to *, ~, - The blocks corresponding to a plurality of arguments must be concatenated in one block. When a block corresponding to a plurality of arguments is concatenated to a block corresponding to one &quot; if ... &quot;, the character of the argument (* is a condition, It is recommended that ~ contains an nfc tag indicating the command to be executed when this condition is true, and a command to be executed when this condition is not true. This is because not only a program block but also a single block is not located in a block column in which blocks are simply arranged one-dimensionally, and when a plurality of blocks are concluded, You can install NFC tags to display them. For example, when a plurality of small parts can be fastened to one large part, an NFC tag indicating a small part to be fastened next to a position where the small parts are fastened can be provided. It is possible to read the NFC of the position to be fastened by the user to know which part of a certain shape should be fastened and to read the NFC tag of the small component and the adjacent NFC tag of the large component before and after fastening the small component, .

Fig. 3 is an example of implementing a physical NFC block corresponding to the &quot; if &quot; statement of a computer program.

As shown in FIG. 3, when constructing a language structure having a plurality of arguments such as &quot; if ... &quot;, and the length of each argument is a formula and the size of which can be changed, it is made into one physical block The block corresponding to the start 101 of the language structure and the conditional end 102, the block corresponding to the end 102 of the language structure, the block corresponding to the end 103 at the time of true, And the end 104 of the work to be performed. Between the block 101 and the conditional end block 102, which means the start of &quot; if ... &quot;, a block column of a formula that can be found to be true and false as shown in Figs. Can come. On the right-hand side of the conditional end block 102, a command string to be executed when the condition is true is placed between the upper "side" and the end block 193, and a command string to be executed when the condition is false is " (Not shown). At this time, two NFC tags 21, 22, which distinguish the nature of two different arguments attached to a block 102 as described above, may be installed under "back" printing and "or" printing.
