Abstract

The present invention relates to a method for processing a barre chord of a virtual guitar. The present invention has the aim of providing a method for smoothly processing a barre chord in a virtual guitar provided as an application program in a mobile communication device having a multi-touch screen. Playing a barre chord involves the index finger simultaneously pressing down on all the strings on the same fret. A touch screen recognizes, as a touched point, the exact center of a continuously connected touch region, and therefore playing the barre chord is also recognized as pressing just one point of the touch region, making it difficult to recognize the barring on the touch screen. Therefore, the method proposed by the present invention analyzes the pattern in which the index finger contacts the touch screen during barring and the pattern of guitar chords in order to play a barre chord so as to define conditions to be interpreted as cases in which barring is performed by a player, analyzes the pattern of touch points every time the locations of touch points change while playing a virtual guitar, and performs a barre chord process only when the pattern falls within the condition that requires a barre chord process. The conditions for a barre chord process can be summarized into three cases in which touch points forming a barre chord range over three or more frets, wherein the three cases include: a first case in which a touch point exists on either the third string or the fourth string at the lowest fret; a second case in which two touch points are recognized at the lowest fret and the locations of the touch points are a combination of the first and fourth strings, of the first and fifth strings, of the second and fourth strings, of the second and fifth strings, of the second and sixth strings, of third and fifth strings, or of the third and sixth strings; and a third case in which three touch points are recognized at the lowest fret. The present invention enables the playing a barre chord to be recognized in the virtual guitar having a touch screen which otherwise might not recognize a long touch region, and enables a barre chord to be more easily inputted through a simple touch input operation using barre chord processing conditions.

Description

How to handle virtual guitars

The present invention relates to a method for processing a virtual guitar barre.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a method for smoothly processing the Barrezu method in a virtual guitar as an application program in a mobile information device having a multi-touch screen. Barre is the main method of pressing all the lines in the same fret by spreading the index finger at the same time.The touch screen recognizes the exact center of the continuous touch area as a touched location, so in the case of Barre, it is recognized that only one point in the center is pressed. It was difficult to recognize.

Thus, the method proposed by the present invention, by analyzing the pattern of the index finger touches the touch screen and the pattern of the guitar chords that should use the Bareju method in the Bareju law to define the conditions that can be interpreted as if the player hit the barre When the virtual guitar is played, whenever the position of the touch points changes, the pattern of the touch points is analyzed and the barre processing is performed only when the condition corresponds to the barre processing.

To summarize the conditions of the barre processing for this,

While the touch points that make up the code span more than three frets,

First, the lowest fret with the touch point, where the touch point is only on

line

3 or 4,

Second, on the lowest fret with touch points, when there are two recognized touch points, the positions of the touch points are (line 1, line 4), (line 1, line 5), (line 2, line 4), ( Combination of any one of line 2, line 5), (line 2, line 6), (line 3, line 5), (line 3, line 6),

Third, three touch points are recognized at the lowest frets having touch points.

According to the present invention, it is possible to recognize that a barre occurs in a virtual guitar having a touch screen that cannot recognize a long touch area, and the barre processing condition makes it easier to input a barre by using a simple touch input. have.

The mobile information device to which the present invention is implemented is an information device to the extent that an application program such as a smart phone can be executed, and should have a touch screen supporting multi-touch.

Hereinafter, the present invention will be described with reference to the drawings.

1 is a screen configuration diagram of a virtual guitar.

As can be seen in the figure, the fingerboard 7 of the virtual guitar is displayed on the touch screen, the frets 8 are displayed on the fingerboard 7, and the guitar strings are line 1 from the bottom (1) and 2 on the fingerboard.

Lines

2, 3, 3, 4, 4, 5, 5 and 6 are indicated in this order.

In the figure, the right direction is the other head direction, the lower fret toward the head direction, and the higher fret toward the body direction, which is the opposite direction.

The present invention relates to a method for recognizing the Barrezu method in such a virtual guitar.

2 shows a barre input.

As shown in the figure, barre is the main method of pressing the index finger and pressing all the lines in the same fret at the same time. Of course, there is also such a big barre, and a small barre pressing only a part of the string with one finger at the same time, but in the present invention will only handle a big barre.

Looking at the drawings, it can be seen that when the index finger is in close contact with the touch screen, it is recognized that the touch point has occurred at the center thereof. In the drawing, the shadow display 11 in black circle is a point recognized by the touch.

This phenomenon occurs because the touch screen recognizes the center of the touch area without a break as the touched position, and thus, even in the case of such a barre, only one point of the center is recognized.

Thus, in the virtual guitar composed of the touch screen, it is difficult to recognize the Barreju method.

The present invention seeks to solve this problem.

First, a pattern in which the index finger touches the touch screen during the barreju method will be described.

In the drawing, the red dot indicates the position of the touch point recognized by the touch screen of the virtual guitar.

When the index finger is completely in contact with the touch screen as shown in (a), it is recognized as a touch at a point in the center.

In other words, after analyzing the pattern of the touched points in the virtual guitar during the play mode, if the fret may have occurred in a fret and the touch point is recognized at the position corresponding to the 3rd or 4th line of the fret, the fret is displayed. You can deal with the frets that have happened.

As shown in (b), when the touch area falls from the first node of the finger, two points are recognized on the touch screen as shown in the drawing. In general, if the player hits a barre, the line 1 and line 6 positions will always be in contact with the fingers. Therefore, when the two touch points to be recognized are divided in half, the two touch points will not be included in any half of the area of the touch screen. However, since the middle portion of the finger will not float in the air, the two touch points will not be recognized in the first line (1) and the sixth line (6) of the virtual guitar, respectively. In addition, since the fingers are attached to both ends of the touch screen, the two touch points will not be gathered at the center and will be recognized simultaneously in the third line 3 and the fourth line 4. In other words, when a touch occurs at these positions at the same time, it is difficult to see that the barre is input on the fret.

To sum it up, it is only one half divided into half (Line 1, Line 2), (Line 1, Line 3), (Line 2, Line 3), (Line 4, Line 5), (Line 4, 6) Line), (line 5, line 6) is not a case of barre,

The combination of two points in the middle of the touch screen, that is,

lines

3 and 4, is not a case where barre occurs.

The combination of the two points on both ends of the touch screen, that is,

lines

1 and 6, can be treated as if the barre does not occur.

The rest of the other combinations: (lines 1, 4), (lines 1, 5), (lines 2, 4), (lines 2, 5), (lines 2, 6), (lines 3) , Line 5), (line 3, line 6) is a case where enough barre can occur.

That is, as a result of analyzing the pattern of the touched points, a barre may have occurred in a fret, and when there are two touch points having the above combination in the fret, the fret may be treated as a fret in which the barre occurred.

When the touch area is separated from the first and second nodes of the finger as shown in (c), three points are recognized on the touch screen as shown in the drawing. In general, you can think of the chords on the higher frets on the guitar, but there are no chords on the lower frets that press these three places at the same time. Accordingly, when three touch points are recognized on one fret and there are touch points at a fret higher than that, the barre may be input to the frets where the three touch points are recognized.

Next, the pattern of the guitar codes that should use the Barrezu method will be explained.

4 is an example of general codes using barre.

As can be seen in the figure, the barre is generally characterized by notes that need to be touched by another finger at a fret higher than two frets above the fret on which the barre is struck. Thus, a condition that can be recognized as a barre can be set to 'a code that spans three or more frets'. Afterwards, the detailed conditions to be added to the above conditions in order to correctly recognize the barre will be found one by one while analyzing the pattern cases of the guitar codes.

Of course, some code uses Barrett but only uses two frets.

5 is an example of codes that span two frets using barre.

As can be seen in the figure, the chords that span the two frets are rarely used chords that a typical player will meet once in a lifetime. In addition, considering that the virtual instrument to which the present invention is applied is not a professional performance but a casual mobile instrument for leisure, it can be seen that such a rare code cannot be input even if it is not possible to enter a code. Therefore, it can be said that the condition that the code to be treated as having occurred is 'code that spans three or more frets' is still valid.

Here's an analysis of code that spans three frets and doesn't use barre.

6 is an example of codes that do not use barre across three frets.

As can be seen in the figure, it can be seen that these codes are the first or second line pressed on the lowest fret. However, as described above, when the index finger is completely in contact with the touch screen for barre, only one point is recognized on the frets, and that point is recognized on

line

3 or 4, so that the point with the touch point over three frets If the touch point is recognized only at one point on line 1 or line 2 on the low fret, it can be considered that the barre does not occur.

Therefore, the condition that 'the code spans three or more frets, and the lowest fret where touch is touched is treated as a barre on the lowest fret when the touch occurs only on one of lines 3 or 4'. In this case, the code as shown in the drawing is not mishandled as having occurred.

Thus, if the code spans three or more frets and touches only one of the third or fourth lines on the lowest fret where the touch occurs, the lowest fret is treated as a barre. You can set the condition to a condition that recognizes the Barrezu method.

Here, as described in the description of the case where the barre is recognized as two points on the touch screen as shown in FIG. 3 (b) described above, when the conditions for the bahrain expression are applied, 'the code spans three or more frets. , At the lowest fret where the touch occurred (lines 1, 4), or (lines 1, 5), or (lines 2, 4), or (lines 2, 5), or (lines 2, 6) ), Or (combination 3, 5), or (combination 3, 6) when two touch points are recognized, the lowest fret is treated as a barre. Can be.

Also, if the bar bar is summarized in the description of the case where the barre is recognized as three points on the touch screen as shown in FIG. In addition, the code may be added to the lowest fret where the touch occurs, and when three touch points are recognized, it is treated as having a barre at the lowest fret.

To summarize the Bahrain recognition conditions derived above,

While the touch points that make up the code span more than three frets,

First, the lowest fret with the touch point, where the touch point is only on

line

3 or 4,

Next, let's verify how efficiently we can recognize Barre under these conditions. The description will be given with a special example rather than a general example.

7 is an example of efficient division by the present invention.

In the drawing, the green point is the point where the player presses the fingertip, and the gray point is the point where the virtual guitar automatically performs the barre input process according to the bahrain condition.

(a) is a case of inputting a Caug code, which is a code that spans three frets, but since the two points on the lowest fret with touch points are not treated as barre (lines 2 and 3), the virtual guitar according to the present invention Will treat these inputs exactly as Caug.

(b) is the case of entering the Fmmaj7 (or FmM7) code, which is a code that spans three frets and is a combination of two points on the lowest fret with touch points (lines 3 and 5). The virtual guitar according to the present invention treats this input exactly as Fmmaj7.

Next, since (c) is a code made over three frets and only a third line is touched on the lowest fret with a touch point, the virtual guitar according to the present invention recognizes this input as a barre. As in d), it is automatically processed by the Fmmaj7 code. However, the code of (c) is a code called B6-5sus4addb9, which is also rarely met. Therefore, when these touch points are recognized in the virtual guitar, the intention of the input is almost always the Fmmaj7 code, not the B6-5sus4addb9 code. Therefore, the virtual guitar according to the present invention recognizes the Fmmaj7 code input of this method very accurately.

Next, exceptions that do not meet the Bahrain recognition conditions completed so far will be described.

8 is an example of an exception.

The figure on the left is the Gaug code. However, if the player inputs the fingertips like this without using the barre, the virtual guitar according to the present invention is a case where only the fourth line is located on the lowest fret having the code and the touch point that spans three frets. An error occurs that recognizes the input as having a barre and automatically processes the barre as shown on the right. However, the code that is input due to this incorrect processing is also a commonly used code called G # 5addb9add11. Therefore, in this case, it is not necessary to perform the barring process exceptionally.

Therefore, when the Gaug code is input to the completed Bahrain expression condition as shown in FIG. 8, the specific exception condition for processing it as a Gaug code without barre processing is' when inputted as shown in FIG. 8 'or' the touch point most. It is desirable to add an exception condition such as' When a touch point is recognized in

lines

1 and 6 on the high fret.

These exceptions are not common, but you can add exception conditions to handle exceptions whenever you find a new exception that needs to be handled.

Next, a description will be given of the flow of the touch signal processing of the present invention to implement the completed bahrain condition.

9 is a flow chart of the present invention.

Play mode begins (1000),

If a touch point change (a new touchdown or a touch-off or drag of an existing touch point) occurs on the virtual board on the touch screen (2000),

Determine whether the newly formed code consists of more than three frets (3000),

If it is not more than three frets, after adjusting the pitch by the new fluctuation without the bare processing (3100), waiting for a new touch fluctuation (2000),

If it is 3 frets or more, the number of touch points on the lowest fret with touch points is determined (4000).

In step 4000, if the number of touch points on the lowest fret is one, it is determined whether the touch point is line 3 or line 4 (5000).

If the touch point is a line other than the third line or the fourth line, after adjusting the pitch by the new change without bare processing (5100), the second touch waits for the new touch change (2000).

In step 5000, if the touch point is line 3 or line 4, it is determined whether there is an exception condition (6000).

If there is an exception condition, after adjusting the pitch by the new variation without bare processing (5100), waiting for a new touch variation again (2000),

If there is no exception condition, after performing the varing process on the lowest fret with the touch point (7000), a new touch change is awaited (2000).

In step 4000, when the number of touch points on the lowest fret is two, it is determined whether the combination of the two touch points corresponds to a preset barre pattern (4100).

If the combination of the two touch points is not a combination corresponding to the preset barre pattern, after adjusting the pitch by the new fluctuation without barre processing (4110), waiting for a new touch fluctuation (2000),

If the combination of the two touch points is any one of the combinations corresponding to the preset barre pattern, the baret processing is performed on the lowest fret having the touch point (4120), and then a new touch variation is waited for (2000). .

In step 4000, when the number of touch points on the lowest frets is three, after performing the barre processing on the lowest frets having the touch points (4200), a new touch variation is awaited (2000).

Repeat this process until the player stops playing.

The process of the present invention has been described above. However, of course, if the conditions in which two or more points are recognized in the freted fret are ignored, that is, the code that spans the 'three or more frets, and the lowest fret with the touch is any of three or four lines. If only one line is touched, the lowest fret is treated as having a barre ', and a virtual guitar that can be fully enjoyed can be implemented. Since other codes can be entered in various forms of fingering at various positions on the fingerboard, even a virtual guitar implemented by such a single condition can enter codes that cannot be entered due to these conditions in different positions. It is. Therefore, in the case of a virtual guitar mounted on a low-spec mobile information device, it is recommended to ignore the following two conditions in order to prevent the timing for outputting a performance sound by increasing the load of the system to handle various conditions. It may be desirable.

Next, an effect of more easily inputting a barre using the present invention mounted on a small mobile information device will be described.

The virtual guitar mounted in a small device such as a smart phone is not supported by the body, such as the actual guitar, it is difficult to catch the barre in the posture as shown in FIG. In other words, if you catch a barre-less code and catch a barre-type code, or vice versa, if you catch a barre-less code and catch a barre-free code, you will immediately grab the device and release it. This makes it virtually impossible to play with rhythm.

The virtual guitar according to the present invention has the effect of solving the problem.

10 shows a simple barre using the present invention.

As shown in the figure, while holding the device securely with the thumb and index finger, you can enter the barre by pressing only three lines without opening the index finger. As shown in the figure, a code is formed over three frets, and a barre is automatically entered into the lowest fret with the touch point because there is only a touch point on the third line on the lowest fret with the touch point. Of course, depending on the player, you can press line 4 instead of line 3.

In the drawing, the black points 11 are points pressed by the finger of the player, and the white points 12 are points automatically input by the virtual guitar.

It is not necessary to implement this, but it is faster to input the virtual guitar input method according to the present invention to the player by displaying the actual recognized point 11 and the point 12 automatically inputted by the virtual guitar as shown in the figure. It is effective to learn.

As described above, the present invention is to classify the barre accurately and input the barre even if the player grasps the barre according to the manner in which the player plays the actual guitar or the barre according to the simple barre method.

Also, in the above condition, except for line 4, 'the code is spread over three or more frets, and if the touch occurs only on line 3, the lowest fret is touched. You can use it as a barre input condition only. In this case, there is an advantage that it is not necessary to put the exception of Gaug mentioned above, but in this case, it is difficult to recognize how to input the barre on the guitar by extending the index finger and learning the barre input method. desirable.

Next, even if a simple barre input is received only in the third line, a method of making the index bar easier to be processed as if the user presses all the lines by extending the index finger as if input from the original real guitar will be described.

11 shows an example of arranging line 3 in the center of the screen.

If you place line 3 close to the center or the center of the screen as shown in the drawing, the touch point touched by one point on every line will be in line 3, which is the center, so you can recognize the simple barre as if you are typing in a real guitar. You can recognize the barre by inputting the index finger as long as you press every line.

The simplified bar 13 shown in the drawing is preferably configured to be automatically displayed in the third line when a touch occurs on the fret seen from the head side among the frets visible on the screen. By doing so, the first-time player can naturally see the simple barre point 13 without learning how to hold the barre. In other words, when the touch on the third fret to grab the code containing the barre, a simple bar 13 (13) appears, and if you press only that point will be able to immediately check that the barre is automatically input. It is preferable that the simplified bar 13 has a sign indicating a barre as shown in the drawing.

All of the methods described above can be recognized as a barre like actual guitar law, and can be recognized as a barre simply by pressing a single point.

However, if you use the method of entering the barre simply by pressing a single point without actually baring like a real state law, it does not matter where the simple bar is located. Therefore, the barre input like the actual state law is not recognized, but the simple bare method will be described in a very convenient manner.

The chords that span the frets higher than that fret and the total of three frets are hard to find while the guitar chord is pressing only the fifth or sixth line on any one fret, so the area between

lines

5 and 6 as shown in the diagram is If you set 13), the shape of the hand holding this simplified barre is much more similar to the actual barre than the simple bare in line 3, so you can feel more realistic. The area is also wider than a single line, making it easier to play.

Fig. 13 shows the actual playing in the case where a simple bar area between

lines

5 and 6 is used.

As shown in the figure, the finger is not stretched close to the touch screen without bending, except that the rest of the fingertips except that the touch screen is different, it can be seen that very similar to the actual barre.

Here is another simple bar method.

14 shows an example of using

lines

1 and 6 as the simplified bar 14.

This embodiment is also included in the above description, except that the above-described method is one of various conditions recognized as barre, and the present embodiment may be made into only this condition.

Since chords that hold the first and sixth lines on any one fret are more difficult to find the chords that are higher than that fret and the total of three frets, as you can see in the drawing, lines one and six at the same time Pressing can be handled as a simple bar press.

As shown in the figure, the bar finger can be easily bent by pressing the sixth line with the fingertip and pressing the first line with the fingertip.

However, the disadvantage of this embodiment is that if the iPhone recognizes only five touch points, such as the iPhone only grabs the F code to touch all five can no longer be tweaked. Accordingly, the device of FIG. 12 is better in a device having five touch points, such as an iPhone, and in the device recognizing six or more touch points, the present embodiment may have a more real barre feeling.

The invention is not limited to that described herein. According to the specification of the mobile information device to which the present invention is carried out, or the pursuit of the mobile information device, the spacing of the guitar strings and the size of the fingerboard may be differently arranged, and the pattern of the index finger touching is also cut accordingly. The present invention is merely described as an example of a virtual guitar that is the size of the actual guitar fingerboard, when implemented in a different size than the embodiment described in the present specification, the barre occurs when the player has two touch points on the frets hitting the barre. The combination of guitar strings can be slightly different.
