Distinguish one's self from others.

On the other hand, the input device used to give a command or input basic data for the computer to perform a specific operation includes a keyboard, a mouse, a touch pad.

Among these input devices, the keyboard detects the pressed key value and provides the scan code to the keyboard controller. The controller converts the scan code by the scan code conversion table and interrupts and transmits it to the system. In the case of the mouse, the relative coordinates detected by the position sensor are provided to the mouse controller to calculate the coordinate values and transmit them to the system.

However, a signal input once through an input device such as a keyboard or a mouse is not re-entered until the user manually inputs it again. This can be cumbersome and inconvenient when mechanical and repetitive input is required.

Therefore, in order to perform a complicated key input more easily, a keyboard having special keys such as some control keys or expansion keys has been developed. Recently, in addition to these keys, hotkeys that perform special functions such as immediately launching a web browser, turning on / off the power, or turning up or down the volume are additionally developed and used. have.

In the case of a combat game, for example, in order to implement a special effect fencing, the user could implement colorful motions such as swinging, turning, and various magics through shortcut keys such as F1 or F2 function keys registered by the user or the game.

In addition, in the case of a dance game, a dance skill is implemented by pressing the arrow direction keys one by one and pressing the space bar as a key for completing an operation.

However, according to the prior art as described above, the user has no choice but to use the key input method defined by the game. In other words, in order to implement a specific motion in the game, the action key set by the game must be pressed. For example, in order to implement the special action, the key combination determined by the game must be pressed according to the timing.

On the other hand, Figure 3 is a block diagram of a mouse pattern recognition system for controlling the operation of the game character according to an embodiment of the present invention.

3, the mouse pattern recognition system for controlling the operation of the game character according to an embodiment of the present invention, the mouse 110, which is installed in the user terminal 100 largely in the form of a program in the user terminal 100 The mouse pattern recognition module 120 may be installed, and the game server 240 and the item server 260 implemented on the internet game service system 200 may be included. In addition, the mouse pattern recognition module 120 may include a preprocessor 121, a feature extractor 122, a mouse pattern comparator 123, a mouse pattern registerer 124, and a mouse pattern determiner 125. .

In the mouse pattern recognition module 120, the preprocessing unit 121 preprocesses the first mouse pattern input in the registration mode and the second mouse pattern input in the game mode and transmits the preprocessing to the feature extraction unit 122.

For example, the preprocessing process removes noise caused by hand shaking or mouse sliding in the input mouse pattern, and extracts and samples the input mouse pattern data at regular intervals, thereby measuring the size of the data. It may include reducing the size to a size suitable for processing.

In addition, the preprocessing unit 121 tilts the input mouse pattern with a size to tilt the input mouse pattern in order to compare the mouse pattern having a different size, the mouse pattern having a different degree of inclination, and the time required to input the mouse pattern with other mouse patterns. The normalization process can be performed so as not to be affected by the degree of progression and the time required.

The feature extractor 122 extracts a feature from the first mouse pattern or the second mouse pattern preprocessed by the preprocessor 121 described above. Features used for mouse pattern recognition may be divided into, for example, a global feature and a local feature. Here, the global feature refers to a feature of the entire input mouse pattern, and includes a time required for input of the mouse pattern, a ratio of the horizontal axis to the vertical axis, an average speed, an average acceleration, and the like. In addition, the local feature is a feature of each position of the mouse pattern that changes with time, and the abscissa coordinates, the ordinate coordinates, the speed of the mouse, and the like may be expressed as a function of time.

The mouse pattern registration unit 123 matches the first mouse pattern from which the preprocessing and the feature are extracted with a series of control commands for implementing a specific motion of the game character, for example, a series of keyboard inputs, to the game server 240. Register.

The user may register a plurality of first mouse patterns by matching them with a series of control commands. Even if the same user inputs the same mouse pattern, there are always variations, so the more the first mouse pattern is registered, the more likely the desired operation is to be implemented. In other words, the mouse pattern newly registered by the user needs to register many similar patterns so that similar patterns can be recognized as the same pattern.

In addition, the mouse pattern registration unit 123 may register one of the representative mouse patterns previously registered in the game server 240 with a series of control commands and register the same in the game server 240.

Since the representative mouse pattern is registered in advance in relation to the plurality of similar patterns in the game server, the user does not need to register many similar patterns one by one, thereby increasing user convenience.

Subsequently, the user may itemize the registered mouse pattern, and the mouse pattern converted into an item may be registered in the item server 250 and sold to another user, or may be purchased from another user and used during game play.

The mouse pattern comparison unit 124 calculates the similarity by comparing the second mouse pattern input from the user with the registered mouse pattern. In this case, the input second mouse pattern may be a mouse pattern from which preprocessing and features are extracted by the preprocessor 121 and the feature extractor 122.

As the similarity calculation method, for example, a method using a parameter (Parametric Approach) or a functional method (Functional Approach) can be used. Here, the method of recognizing the mouse pattern by configuring various types of feature values such as the time spent inputting the mouse pattern, the average speed, the aspect ratio of the mouse pattern, and the aspect ratio as a vector is called a method of using a mouse. The method of recognizing mouse patterns by making velocity or acceleration a feature function of time is called a functional method.

In the method using the parameter, the similarity between the mouse patterns is calculated by calculating the distance of the feature vector obtained from the two mouse patterns. In addition, in the functional method, similarity between mouse patterns may be calculated using dynamic programming (DP) matching, root mean square (RMS) error calculation, and correlation. In general, the time required to compare the mouse pattern is much longer than the method using the parameter, but the accuracy of recognition is higher.

The DP matching method, which is a representative method for calculating the similarity between two mouse patterns in a functional method, first finds a corresponding point of each mouse pattern in another mouse pattern and matches them with each other. Then, the difference between the feature values between two corresponding points is obtained, and the difference is accumulated to determine the similarity between the two mouse patterns. In this case, the lengths of the two mouse patterns may be changed linearly while the total length may be different, or the non-linear length may be different. At this time, the length between the mouse patterns is corrected through a time normalization process, and since the DP matching method has a time normalization function on its own, there is an advantage of not having to perform time normalization separately.

The mouse pattern determination unit 125 selects a mouse pattern whose similarity is greater than or equal to a preset threshold based on the similarity calculated by the mouse pattern comparison unit 124. In other words, based on the similarity between the currently input second mouse pattern and the pre-registered mouse patterns, a mouse pattern having a similarity to or above the second mouse pattern is selected from among the registered mouse patterns. If there is a mouse pattern having a similarity or more than a threshold, it is transmitted to the game server 240. If there is no mouse pattern having a similarity or more, the operation is not performed.

The mouse pattern determination unit 125 may select a mouse pattern having the highest similarity among the plurality of mouse patterns having similarity more than a threshold.

When the game server 240 receives the mouse pattern from the mouse pattern determination unit 125, the game server 240 implements the same operation of the game character implemented by a series of control commands matching the received mouse pattern in the actual game or Implement with weights. When the user succeeds in reproducing the registered mouse pattern, if the system provides a strong combat damage or a dance skill score with weights, the user's interest can be effectively induced.

Therefore, the mouse pattern recognition system for controlling the motion of a game character according to an embodiment of the present invention implements the game motion of the character through pattern recognition of the mouse instead of a combination of keys or shortcut keys preset in the game.

In the mouse pattern recognition system for controlling the motion of a game character according to an embodiment of the present invention, for example, after matching a specific mouse pattern with a combination of a specific key in the exercise book mode, the mouse is stored and stored in the specific mouse in a real game. Implementing a pattern produces the same effect as a combination of specific keys. In this case, the specific mouse pattern may be used in combination with a mouse button or a keyboard input.

In addition, the representative mouse patterns and similar patterns of each representative mouse pattern are registered in advance in the game server, and the user may use them to match a set of key combinations desired by the user. In this case, since the user can omit the process of registering a large number of similar patterns, user convenience is increased.

On the other hand, Figure 4 is a diagram illustrating a registration screen of the mouse pattern recognition system for controlling the operation of the game character according to an embodiment of the present invention, Figure 5 is a game in the mouse pattern recognition system according to an embodiment of the present invention It is a figure for demonstrating the motion control of a character.

Referring to FIG. 4, in the mouse pattern recognition system for controlling the motion of a game character according to an embodiment of the present invention, a user may register his or her mouse pattern in a registration mode, for example, a game character in a practice field. A series of control commands for implementing a specific operation of may be registered by matching with a specific mouse pattern.

That is, in the practice field, after inputting a series of key combinations corresponding to the operation of the game character on the left side of the screen in the key input window 420 below the key input unit 410, the mouse pattern input window below the mouse pattern input unit 430 In operation 440, a second mouse pattern is input using a mouse.

Accordingly, the game character is operated by replacing the complicated key input only with the second mouse pattern inputted in the mouse pattern input window 440. For example, while the mouse is moved while the left mouse button is pressed during the actual game, when the input second mouse pattern matches the mouse pattern registered by the user, the game character implements a specific action.

Too complicated movement lines, for example, movement of a game character or a jump movement is difficult to express in a mouse pattern. Therefore, in a competitive game or the like, the movement of a sword, the movement of a leg, an arm, or the like can be limited.

FIG. 5 is a diagram illustrating matching of a three-character mouse pattern with a series of control commands for implementing a continuous motion of a top kick, a leg folding, a bottom kick, and a leg folding in a martial art game.

Reference numeral 510 denotes a series of keyboard inputs which are a series of control commands, reference numeral 520 denotes an action of a game character corresponding to a series of control commands, and reference numeral 530 denotes a mouse pattern corresponding to a series of control commands. Such a mouse pattern can be registered a plurality of similar patterns by the user.

Meanwhile, the overall flow of the mouse pattern recognition process according to an embodiment of the present invention is largely divided into a registration process and a recognition process. First, the registration procedure may include an input process, a preprocessing process, a feature extraction process, and a registration process, and the recognition process may include an input process, a preprocessing process, a feature extraction process, a comparison process, and a determination process.

6 is a flowchart illustrating a mouse pattern registration method according to an embodiment of the present invention.

Referring to FIG. 6, in the mouse pattern registration method according to an embodiment of the present invention, when a first mouse pattern is input from a user using a mouse in a mouse pattern registration mode (S610), the input first mouse pattern is input. A preprocessing process (S620) and a feature extraction process (S630) are performed.

The pretreatment process (S620) is largely performed for three purposes. The first purpose is to remove noise, which is to remove noise caused by hand shaking or mouse sliding in the input mouse pattern. The second purpose is sampling, which selects the input mouse pattern data at regular intervals and reduces the size to a size suitable for processing the size of the data. Finally, in order to compare the mouse pattern with a different sized mouse pattern, the mouse pattern with a different degree of tilt, and the time taken to input the mouse pattern with other mouse patterns, the inputted mouse pattern is compared with the size, the degree of tilt, and the time required. Perform normalization processing so that it is not affected.

In the feature extraction process (S630), a feature is extracted from the mouse pattern signal that has passed through the aforementioned preprocessing process (S620).

The registration process S640 registers the first mouse pattern, from which the preprocessing and the features have been extracted, by matching with a series of control commands.

Subsequently, the user may itemize the registered mouse pattern (S660), and the mouse pattern converted into an item may be sold to another user or purchased from another user and used during game play.

On the other hand, Figure 7 is a flow chart illustrating a method of implementing a game action by mouse pattern recognition according to an embodiment of the present invention.

Referring to FIG. 7, in the method of implementing a game operation by mouse pattern recognition according to an embodiment of the present invention, first, when a second mouse pattern is input from a user in a game progress mode (S710), the second mouse The preprocessing is performed on the pattern (S720), and the feature is extracted on the preprocessed mouse pattern (S730).

Thereafter, the mouse patterns are compared with each other in order to calculate similarity with the registered mouse patterns with respect to the mouse pattern from which the preprocessing and the features are extracted (S740), and a determination process is performed (S750). Here, the steps S710 to S730 are similar to the steps S610 to S630 of the game operation method by the above-described mouse pattern recognition, and thus detailed description thereof will be omitted.

The comparison process S740 calculates the similarity between the second mouse pattern from which the preprocessing and the features are extracted and the registered mouse patterns.

The determination process (S750) selects a mouse pattern having a similarity to or greater than a threshold value from the currently input second mouse pattern among the registered mouse patterns. If there are a plurality of mouse patterns having a similarity or more than a threshold, the mouse pattern having the highest similarity is selected. If there is no mouse pattern whose similarity is greater than or equal to the threshold, the next step does not proceed.

Thereafter, the motion of the game character implemented by a series of control commands matching the selected mouse pattern is embodied equally or weighted in the actual game (S760). In a real combat game or dance game, if the user succeeds in reproducing the registered mouse pattern, if he / she provides more powerful combat damage or dance skill scores by weighting than that implemented by a series of control commands defined by the system, It will be able to double the fun of the user.

8A to 8C are diagrams illustrating a mouse pattern recognition process according to an embodiment of the present invention, respectively.

In fact, the pattern of the mouse input by the user is irregular as shown in the left side 610 of FIG. 8A, and smoothing is required as shown in the right side 620 of FIG. 8A.

At this time, the direction, angle, and length are considered by dividing into several points with respect to a straight line in one direction. In the simplification process, a dot reduction algorithm that simplifies the number of points may be used.

For example, if five points were extracted as shown in the left side 630 of FIG. 8B while drawing the first line, the line was reduced to three as shown in the right side 640 of FIG. 8B. Can be used to simplify the process. For each line between a point and a point, a set of lines (for example, a set of lines having directions and lengths from 1 to 70) can be selected.

8C is a diagram illustrating a DP matching method in the case of the Chinese character '乙' (new t).

DP matching is a method of calculating similarity by performing correspondence between two elements using dynamic programming. Similarity can be used to determine which pattern the complex deformed pattern was similar to. Therefore, the degree of matching between the reference pattern and the distorted or deformed input can be evaluated.

The DP matching method is performed by iterative calculation, and its configuration is simple, and it is the method that can be most stably recognized in pattern recognition and mouse pattern recognition having various patterns. The DP matching method uses a chain code sequence, and the feature code sequence between the recognition target pattern chain code sequence and the input pattern is correlated with each other in an optimal path so that the distance between patterns is minimized. In this case, the recognition rate may be obtained by measuring the similarity between the input pattern and the previously trained pattern using the chain code and the structure code.

9A and 9B are diagrams illustrating another example of mouse pattern recognition according to an exemplary embodiment of the present invention.

FIG. 9A is a diagram illustrating a mouse pattern for implementing an action such as a kick, an air sword, etc. in a competitive game. By drawing the mouse pattern shown in FIG. 9A, a user can easily implement operations such as a kick or an air sword attack, which are implemented by complex key combinations.

9B is a diagram illustrating a dance operation in a dance game. For example, if you want to pre-select the body keys of characters such as left arm-A, right arm-S, left leg-Z, and right leg-X, and move the arms to the left and right, press the A and S keys simultaneously. In the pressed state, by moving the mouse as shown, a desired action can be achieved.

10 is a signal flow diagram illustrating a mouse pattern registration and recognition process between a user terminal and an internet game service system according to an embodiment of the present invention.

Referring to FIG. 10, when the user terminal 100 accesses the game web site 200 (S1110), the game web site 200 transmits a game program and a mouse pattern recognition module to the user terminal 100 in the form of a program. Download (S1120).

The game web site 200 receives mouse pattern information matched with a series of control commands for implementing a specific operation of a game character from the user terminal 100 (S1130) and registers it in a database (S1140).

As described above, the mouse pattern information may be preprocessed information that has undergone sampling and normalization. Also, the feature point may be extracted from the preprocessed mouse pattern information.

In addition, the game website 200 may match a plurality of mouse pattern information with a series of control commands so that similar mouse patterns may be recognized as the same mouse pattern. In addition, a representative mouse pattern associated with a plurality of similar mouse patterns may be provided to reduce the inconvenience of a user registering a plurality of similar mouse patterns.

In addition, the mouse pattern information may further include one or more of mouse button information and keyboard input information as well as a mouse pattern.

During the actual game, when the character motion implementation signal including the registered mouse pattern information is received from the user terminal 100 (S1150), the game character's motion is based on a series of control commands matching the registered mouse pattern information. It implements (S1160). The game website 200 may implement the same operations as those implemented by a series of control commands or may implement weighted operations.

In an actual combat game or dance game, if the user succeeds in reproducing the registered mouse pattern, the system may be configured to provide a strong combat damage or a dance skill score.
