Description

 [0001] The present invention relates to a method for inputting letters using motion recognition,

More particularly, the present invention relates to a technique for recognizing an operation signal corresponding to a predetermined number of function keys in addition to an operation signal corresponding to 12 telephone keypads and driving the corresponding key, And a technique for inputting characters in accordance with a specific input rule so as to concretely recognize a predetermined limited operation signal to enable all characters to be input.

Efforts have been made to find a convenient input method in various fields of terminals, and many techniques for operation and operation of a terminal through motion recognition using motion recognition cameras have appeared.

Korean Patent Registration No. 10-0738014 'In a system and method for providing a short message transmission service to a mobile communication terminal using motion recognition, an operation recognition unit is installed in a mobile communication terminal, and a camera Stores a variety of operations of the user of the mobile communication terminal and stores the generated short messages in the mobile communication terminal as motion recognition data, drives the camera mounted on the mobile communication terminal, And a system and a method for transmitting a corresponding short message to a designated mobile communication terminal when a motion recognition application is executed to detect the same operation as an operation stored in the motion recognition data.

That is, if a specific operation is recognized in a program execution state after storing sentences corresponding to a specific operation signal, it is a method of transmitting a sentence that has been preformatted in correspondence with a specific operation, so that it is not possible to input various characters according to a user's request and a situation.

In addition, Korean Patent Registration No. 10-0630806, 'command input method using motion recognition device', discloses a method of allowing input of up to the unit of the Korean alphabet through motion recognition, however, , It is difficult for the user to learn and input many kinds of abstract operation signals corresponding to at least 19 Hangul consonants and 10 Hangul consonants Actually, it is difficult for the users to know the operation signals and input characters.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems and disadvantages described above, and it is therefore an object of the present invention to provide an apparatus and method for performing an operation corresponding to a keypad of a telephone key, And ultimately to provide a convenient character input environment without requiring the user to learn a complicated operation signal.

According to an aspect of the present invention, there is provided a character input method using motion recognition,

A telephone key operation unit corresponding to twelve telephone keys and a function recognition unit for registering a function key operation unit corresponding to a predetermined function key and a plurality of telephone keys in which basic characters of characters are arranged, A step of inputting an operation signal registered in an operation recognition definition unit by a user, a step of inputting an operation signal inputted by a user into a character recognition mode, And operating the functions of the corresponding 12 telephone keys or function keys as a result of the recognition.

In the above method, the telephone key operation unit corresponding to twelve telephone keys may be constituted by twelve operations that are easy for the user to understand. For example, the digits of the digits 1 to 10, You can use the Korean sign language operation, which means the number 30. In addition, an operation corresponding to twelve keypads can be configured using the operation of the handwriting signal using the operation of the two arms.

The above two types of operation signals are classified into operation and operation so as to recognize that the operation is continuous operation by inputting two operations consecutively by using 12 operation signals in each stationary state It is preferable to provide a motion classification signal. Otherwise, if the operation is input twice consecutively, it is necessary to define a separate operation signal. For example, if the operation signal corresponding to the number button '2' needs to be inputted twice consecutively, the Korean sign language signal corresponding to '2' is operated, then the left hand moves once and then returns to the correct position You can define it as an action.

If you do not want to use this motion classification signal, you can define 12 motion as dynamic motion instead of stop motion. For example, the operation of drawing numbers '0' to '9' in the same manner as drawing a number '1' by hand in air is defined as an operation signal corresponding to ten telephone number buttons. With a corresponding operation signal, an operation of drawing a square may be defined as an operation signal corresponding to the # button.

It would be desirable to minimize the confusion of recognition in the motion recognition camera and to construct each motion signal in a direction for quickly inputting the motion signal and, if necessary, modify it to a deformation motion.

It is also necessary to configure a function key operating unit including operation signals corresponding to functions such as entry into and exit from the operation signal mode in addition to the operation signals corresponding to the 12 keypads.

Such function key operation part will be implemented according to the field and service in which this method is used. For example, 'cancel', 'completion', 'search', 'call', ' English, '' mode start ',' mode end 'and so on.

Therefore, the function key operation unit is composed of the operation signals corresponding to the above functions, and when the operation is recognized, the corresponding function will be performed.

In addition, in the process of registering the operation signals to be registered in the operation recognition definition unit composed of the keypad operation unit and the function key operation unit, the signals are differentiated so that the respective operation signals are not recognized as different signals, Lt; / RTI >

In the above-mentioned motion recognition character input method, the character combination unit for placing the basic character of the character in 12 telephone keys and inputting the character in accordance with a specific input rule may use the character input technique using other telephone keyboards on the market, It would be desirable to utilize the contents of the patent registration No. 10-0198270. The Korean character input method of Korean Patent Registration No. 10-0198270 is different from the input method using the toggle or conversion method because the input of the character is inputted in the Hangul free writing form and the input of the button key indicating the end of the character In the recognition character input method, it is possible to easily confirm the input end of Hangul characters in the system, thereby reducing the error or erroneous input.

In the above-mentioned motion recognizing character input method, referring to the previously input character, it can be utilized for the probabilistic judgment on the recognition of the currently inputted motion. For example, if the character 'Up' is entered, then the recognition of the corresponding action of the 7th button or the star button (* button) of the telephone key is inputted and the letter 'absent' It is easy to judge the probability of motion recognition. It is preferable that such an application is extended not only to the unit of the cursor but also to the word unit and the sentence unit so as to predict the case of the operation signal that can be input next, and to use the same for increasing the efficiency of motion recognition.

The character input method using the motion recognition as described above includes a telephone key operation unit composed of twelve operation signals that are easy to be recognized by a user and a function key operation composed of operation signals corresponding to a predetermined function key operation Because it is limited to wealth

It is possible to reduce the burden on the user to learn the operation signal, thereby increasing the availability and providing the convenience of controlling the terminal using a simple operation signal.

Also, from the viewpoint of the operators constituting the motion recognition system, it is possible to construct a motion recognition character input terminal and a service with low cost and high recognition efficiency by configuring a light motion recognition system.

In addition, the present invention can be used as a character input method using an operation recognition camera, but can also function as a new communication means between a user and a user or between a general person and a disabled person. It means that it can be used as a new Hangul sign language system using only a simple signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments.

FIG. 1 is a flowchart illustrating a character input process using motion recognition according to the present invention.

Fig. 2 shows an example of a character combination part used in the present invention.

FIG. 2 is a product commercialized by applying Korean Patent Registration No. 10-0198270 and is used for inputting Korean characters by pressing a number button on a PC remote control mounted on a Windows 7 operating system of a PC. 2, 19 consonants are arranged in a specific order on ten numeric buttons, and ten Chinese vowels are characteristically arranged on ten numeric buttons. Then, the * button is used as a one-letter function key, The # button is used as the Shift Key and the Diphone Synthesis function key. For example, if you want to enter the Hangul code, press the button in the same order as '0 3 2 3 5 4 * # 2 5 * 3 7 * 8 5 # 3 *'.

FIG. 3 shows an example of a telephone key operating unit usable in the present invention.

Fig. 4 shows an example of a function key operation unit usable in the present invention.

A character input process using motion recognition will be described with reference to the above drawings.

If the user wishes to input the character " coex at 7:00 am " according to the present invention, the user inputs a 'conversion to character input mode using motion recognition' to the function key operation unit 311 in front of the motion recognition camera connected to the terminal, As shown in FIG.

Then, the terminal recognizes the operation through the operation recognition camera and switches to the character input mode using the operation recognition to wait for the next operation signal.

In order to input the 'Hangul' character in the state of knowing the Hangul character arrangement and the input rule as shown in FIG. 2, the user registers with the phone key operation unit 350 in correspondence with the '1 0 4 * 3 5 8' And sequentially executes the operation signals corresponding to Fig.

In response to each of the operation signals of the telephone key operating unit 350 sequentially executed, the corresponding characters are input to the screen of the terminal. That is, when the telephone key operation signal of FIG. 3 corresponding to the number button '1' is input, a consonant of 'A' is inputted according to the rule of the character combination unit 210, When the telephone key operation signal is inputted, the character '' is inputted according to the rule of the character combination unit 210. Then, when the telephone key operation signal corresponding to the number button '4' is inputted, 'long' is inputted according to the rule of the character combination unit 210. Then, when the telephone key operation signal corresponding to the * button is input, one letter 'long' is completed according to the rule of the character combination unit 210, and then the telephone key operation signal The character 'long' is input according to the rule of the character combination unit 210. [ Then, when the telephone key operation signal corresponding to the number button 5 is inputted, the character 'length' is inputted according to the rule of the character combination unit 210. Then, when the telephone key operation signal corresponding to the number button 8 is inputted, the character 'GILDONG' is inputted according to the rule of the character combination unit 210. [ Then, when the telephone key operation signal corresponding to the * button is inputted, the character 'Gil-dong' is completed according to the rule of the character combination unit 210.

Then, when the corresponding operation signal of FIG. 4 defined as " switch to the numeric input mode " is executed, the terminal enters the number input mode and waits for the next operation signal.

Next, when the telephone key operation signal corresponding to the number button '7' is inputted, the number '7' is inputted according to the rule of the character combination unit 210, and characters up to 'Gil Dong 7' are inputted. Then, when the telephone key operation signal corresponding to the * button is input, the number input mode is terminated according to the rule of the character combination unit 210, and the mode is switched to the Hangul input mode again to wait for the next operation signal input.

Next, the character input process up to 'Kill 7:00' is omitted because it is obviously understood by the above description. When the corresponding operation signal of FIG. 4 defined as " switch to English input mode " is input in the state of 'at 7', the terminal switches to the English input mode and waits for the next operation signal.

Then, when the telephone key operation signal corresponding to the number button '2' is input, the character 'a' is inputted at the time of 7:00 am in accordance with the rule of the character combination unit 210. Then, when the hand performing the operation signal is moved to the left, and then the telephone key operation signal corresponding to the number button '2' is inputted again, the ' Quot; b " is input. Then, when the hand performing the operation signal is moved to the left, and then the telephone key operation signal corresponding to the number button '2' is inputted again, the ' Quot; c " is input.

That is, as in the case of an English input method generally installed in a domestic mobile phone, the telephone key operation signal corresponding to the number button '2' is input as if the user inputs the alphabetical character 'c' by pressing the button 2 three times within a limited time Run three times and enter the letter 'c'. In addition, when a telephone key operation signal is transmitted and then moved to the left side, the same telephone key operation signal is executed twice.

The subsequent process of inputting alphabetic characters is omitted because it is a level that can be easily understood based on the above description. Thus, after a sentence 'coex at 7:00 am' is inputted, the 'change to the standby screen for inputting the telephone number of the other party for sending a text message' corresponds to the operation corresponding to 'transmission' defined in the function key operation unit When the signal is executed, the terminal switches to the idle screen in which the phone number of the other party to which the text message 'to coex at 7:00 am' is to be transmitted.

As shown in the above description, the character combination unit has an input mode for inputting characters such as Korean, English, symbols, and numbers, and other character input modes such as Japanese, Chinese, and the like can be added.

In addition, as shown in the above description, the method of combining Hangul characters in the character combination unit can use the so-called 'Hangul code' input method of FIG. 2, or use it in domestic mobile phones such as' Other Hangul input methods may be used.

In addition, an operation signal as shown in FIG. 3 is exemplified as one example of a telephone key operation unit composed of twelve different operation signals, and various types of operation signals may be used for the purpose of increasing the efficiency of motion recognition, It is obvious that it can be utilized. It is also possible to use a dynamic-type operation signal unlike the operation signal of the stationary-type as shown in FIG. For example, an operation signal for drawing numbers '0' to '9' by hand, an operation signal for drawing a triangle, and an operation signal for drawing a square may be defined as operation signals corresponding to twelve telephone keypads.

The use of such a dynamic type operation signal is advantageous in that it is not necessary to define a separate operation for distinguishing an operation signal even when the same operation signal is repeatedly input two or more times. However, there is a disadvantage in that the time required for the execution of the operation signal is longer than that of the static operation signal. Therefore, depending on the service field and the product, whether to use the dynamic operation signal or the static operation signal You can use it.

The function key operation signal belonging to the function key operation unit 310 is used by registering the function keys required according to the terminal or field of use of the present invention. For example, if it is used in a smart TV, related commands necessary for driving a smart TV such as 'channel search', 'sound increase', 'lower sound', etc. are registered as a function key operation signal.

As described above, according to the present invention, it is possible to input characters by using twelve easy-to-understand operation signals, thereby providing the user with ease of learning and ease of operation,

It provides operators with the opportunity to build lightweight, low-cost, high-recognition-efficiency motion recognition character input systems and services.

The present invention can be widely used in a character input field through motion recognition in a game machine, a character input field through motion recognition in a smart phone, a smart TV, a character input field through motion recognition in a PC, and an interface with a robot.
