DESCRIPTION OF THE PREFERRED EMBODIMENTS [Configuration of Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG.
1 is a schematic configuration diagram of a game device according to an embodiment of the present invention, in which (a) is a front view and (b) is a right side view. The game device of the present embodiment includes a main body 10 provided with a control unit 1 and the like, and an electronic guitar 20 as input means. The main body 10 has a 29-inch display 11.
And two kinds of loudspeakers 12 for treble and bass, an operation unit 13 in which various operation buttons are arranged, and spotlights 15 provided on both sides of a signboard at the top.

FIG. 2 is a detailed view of the electronic guitar 20. As shown in FIG. 2, the electronic guitar 20 includes twelve fret switches 21 using a pressure sensor, one string switch 22, a mute switch 23 using a pressure sensor,
And an arm 24 with a volume. The fret switch 21 corresponds to a portion separated by frets, which is a projection that separates the surface of a rod-shaped base plate that holds a string with an actual guitar, and the string switch 22 corresponds to a bullet portion of a guitar. is there. In the electronic guitar shown in FIG. 2, for convenience of description, fret switches are numbered from 1 to 12 in order from the right. Further, the fifth fret switch has, for example, a small projection formed thereon so as to be understood by touching with a finger. The mute switch 23 is for simulating an actual guitar mute playing style. After playing the string switch, the sound can be stopped by pressing the mute switch with the palm of the right hand, and by playing the string switch while pressing the mute switch, a mute playing technique similar to that of an actual guitar is possible. When the player presses the mute switch, the range of timbres is expanded, and the feeling of playing the electronic guitar can be made closer to the real thing. The arm 24 is a tremolo arm for applying vibrato to the sound.
By applying vibrato at an arbitrary timing, the player can assert himself in the same manner as a real guitar. When the player presses the fret switch and plays the string switch, the chord corresponding to the pressed fret switch is reproduced from the speaker of the main unit. That is, in the present game device, the player presses the fret switch and plays the string switch, thereby reproducing the same sound of six strings as the actual guitar, so that even a beginner can easily play a difficult chord on the guitar. it can.

FIG. 3 is an enlarged view of the string switch 22 of the electronic guitar 20. The string switch 22 is rotatable as shown in FIG. 3, and its movement is transmitted to an analog volume (string volume), and the amount of movement that has been played is converted to a digital value and sent to the control unit 1. Can be Assuming that the neutral part is 0, data of a fluctuation range as shown by an arrow in FIG. FIG. 4 is a diagram for explaining the output of the chord volume, in which the horizontal axis represents time and the vertical axis represents output values. The control unit 1 uses this data to
The timing at which the player performed is determined, and the sound is reproduced. By the way, assuming that the strings of a real guitar are played, first, as shown in FIG. 5, a string is applied to a finger to generate tension. The finger then releases the tension on the string, producing a sound. Then, the strings return. Thus, a real guitar emits sound through three processes. FIG. 6A shows these three processes by the operation of the string switch 22. The operation of the string switch 22 is transmitted to the string volume, and the output of the string volume is displaced as shown in FIG. This displacement is sent to the control unit 1 as multi-valued data that is further carved every 1/60 second. In a conventional device using a guitar as an input means, a sound is generated at the following timing. However, in such a method, the timing at which the sound is generated is different from the sound generation timing of the sound on the actual guitar, so that the player feels strange. On the other hand, in the present embodiment, the control unit 1 calculates a difference between the transmitted multi-valued data and the latest data for each data, and reproduces a sound when the difference becomes negative. . That is, in the present embodiment, since the sound is reproduced at a timing close to the actual timing of the guitar, it is possible to give the player the same feeling as when actually playing the guitar.

Also, in an actual guitar, the sound output is different between when the strings are played from top to bottom and when the strings are drawn from bottom to top. Therefore, when the string switch is played from top to bottom, Different sounds may be reproduced when playing from the bottom up. In the present embodiment, this playing style does not affect the score, and does not give a performance instruction to that effect. Of course, the display of the rendition style may be performed and points may be added to the score.

FIG. 7 is a control block diagram of the present embodiment. The electronic guitar 20 includes a pressure-sensitive sensor 21a provided on a fret switch, an analog-to-digital converter 21b for binarizing an output value of the pressure-sensitive sensor with a predetermined threshold value, and a 4-bit signal from each analog-to-digital converter. , A string volume 22 a that moves in conjunction with the string switch 22, an arm volume 24 a that moves in conjunction with the arm 24, and a pressure sensor 23 a provided in the mute switch 23. And an analog-to-digital converter 23b for converting the analog signal into a digital signal at a predetermined threshold. The fret switch is 2
There is no point in holding down more than one place. When the player presses two or more fret switches, it is sufficient to reproduce the sound of the fret switch near the base. Therefore,
In order to indicate the state from 0 in which the fret switch is not pressed to 12 in which one of the fret switches is pressed, it is sufficient that 0 to 12 can be identified. Therefore, if the data width of the output of the encoding converter 21c is 4 bits, Good.

The main unit 10 includes an amplifier 4 in addition to the control unit 1.
And a display 29 and the like. The control unit 1 includes a ROM 1c in which a game control program is stored, and a RAM 1 that temporarily stores various input data, calculation results, and the like.
b, a CP that controls the entire game by reading and executing a control program stored in the ROM 1c.
The system includes a system board 2 having a U1a, a sound source 1d, and an input / output board 3. Data from the chord volume 22a and the arm volume 24a are sent to the input / output board as multi-value data, and data from the encode converter 21c and the analog-to-digital converter 23b are sent to the input / output board as binary data. The CPU 1a reads out the control program recorded in the ROM 1c and generates a screen to be displayed on a display based on various data sent from the electronic guitar. In the present embodiment, a score object and a character whose rubber ball is jumping (hereinafter, also simply referred to as a ball character) are displayed on the screen. The CPU 1a sends data to the sound source 1d to instruct reproduction of a sound. The sound source 1d samples and stores the sound of playing the actual guitar chord in advance, and reproduces the corresponding guitar sound in accordance with the instruction of the CPU 1a. Therefore, by operating the fret switch 21 and the string switch 22 of the electronic guitar 20, the player can play the chord of the guitar and enjoy the reproduced sound of the guitar.

FIG. 8 is a flowchart for recognizing that a string switch has been played. In step S1, the value of the string volume and the speed of change are monitored. While monitoring the string volume, it is determined whether or not the absolute value of the string volume is equal to or greater than the reference value (step S2). If it is equal to or less than the reference value, there is no need to emit a sound, and the process returns to step S1. If it is equal to or greater than the reference value, the process proceeds to step S3, and it is determined whether or not the rate of change of the string volume is equal to or greater than the reference value. If the speed of the change is equal to or less than the reference value, for example, if the strings are slowly changed, no sound is produced even with an actual guitar, so even in the present embodiment, the process returns to step S1 without reproducing the sound. Continue monitoring. By the judgment of step S3,
When the value of the string volume changes at a speed equal to or higher than the reference value, the process proceeds to step S4, and it is determined whether or not the change in the value of the string volume has reversed from increasing to decreasing. If it is not inverted, the process returns to step S1, and if it is inverted, the sound source 1 reproduces the sound corresponding to the pressed fret.
d.

[Method of Performing] Next, a method of performing using the electronic guitar in the present game apparatus will be described. Operation unit 1
With the selection buttons provided in 3, select whether to play alone or two people, and press the game start button. When the play by one person is selected, the screen shown in FIG. 9 is displayed on the display, and when the play by two persons is selected, the screen shown in FIG. 10 is displayed on the display. In the following, for simplicity, the description will be made with reference to a screen when playing alone, but the same method can be used when playing with two people.

In the screen shown in FIG. 9, a musical score object 30, a timing line 31, and a ball character 32 are
The picture 33 of the electronic guitar is in the center and the fitness meter 34 is in the lower part.
Is displayed. The musical score object 30 is drawn so as to resemble the surface of a guitar-like base plate, and has a narrow portion 3
0a is a portion indicating the beginning of a sound, and an area 30b is a portion for displaying a fret switch that the player wants to press. For convenience of explanation, the narrow portion 30a is referred to as a fret image portion. The numerical value assigned to the fret image section corresponds to the number of the fret switch of the electronic guitar.
Each region 30b corresponds to a guitar chord. The score object is scroll-displayed by the CPU from the left side to the right side of the screen. Each of the twelve fret switches displayed in the electronic guitar picture 33 is actually
They are color coded in different colors for easy viewing. The fitness meter 34 decreases sequentially when an incorrect performance is performed, and the game is over when the fitness meter becomes zero.

FIG. 11 is an enlarged view of the musical score object for explaining the performance timing. The player presses the fret switch specified by the score object scroll-displayed from right to left on the screen, and flicks the string switch at the moment when the fret image portion of each area of the score object overlaps the timing line. In the state of FIG. 11A, the numeral 5 is attached to the fret image portion, and the fifth region is displayed in a color corresponding to the fret (in FIG. 11, hatched), so that the player has 5 Press the second fret switch with your finger. The screen is scrolled, and the string switch is played at the moment when the fifth fret image portion overlaps the timing line as shown in FIG. If the wrong fret switch is pressed or played at the wrong timing, the health meter will decrease, and when the health meter runs out, the game will be over at that moment. If a song is played before the physical fitness meter runs out, the stage is cleared and the next song can be played. In the present embodiment,
The fret to be pressed is indicated not only by the musical score object but also by giving a triangle mark near the corresponding fret of the electronic guitar picture 33 on the screen as shown in FIG. This allows even beginners to easily play difficult guitar chords. In this embodiment, when the player presses the wrong fret switch and plays the string switch, an incorrect sound is produced.

In this embodiment, an object having a color corresponding to the fret pressed by the player may be displayed. Thereby, the player can easily confirm whether or not the fret pressed by the player is correct.

FIG. 12 is an enlarged view of the musical score object for explaining the release. In the present game device, the concept of "sound length" is introduced. The released sound can be cut off by releasing the fret switch being pressed, newly pressing the fret switch inside the fret switch being pressed, or pressing the mute button. FIG. 12A shows a state in which the fret image portion and the timing line overlap, and in this state, the player plays the string switch. Thereby, a sound is reproduced.
If the finger is pressed down to the state shown in FIG. Then, when the fret switch is released when the timing line is located at the end of the area as shown in (c), the reproduction ends. You may make it reflect the good and bad hands of this release on a fitness meter.

[Rhythm-taking technique] Next, a technique for teaching a rhythm to a player will be described. In a conventional game device for performing a performance, a player who cannot take a rhythm is merely informed of a mistake. For this reason, the player did not know how to improve. Therefore,
In the present embodiment, a display that makes it easy for the player to take a rhythm and a method of informing the player of the mistake to raise the ambition to improve are devised.

In the present embodiment, in order to make it easier for the player to take the timing, a place on the screen where it is easy to enter the field of view of the player, in the example shown in FIG. indicate. If this bouncing ball is programmed to move up and down in a parabola as shown in FIG. 13 according to the law of nature, the player can easily take a rhythm. In FIG. 13, the horizontal axis indicates time, and the vertical axis indicates the position of the ball character. The movement of this ball is reasonable even in light of the orchestra's conducting method. The character of this ball is y = −at ² + bt (a> 0, 0 <t <b
The vertical movement is repeated according to the formula of / a). The player can play the string switch with good timing by playing the string switch at the timing when the ball character is at the bottom while watching the ball character. As a result, even a beginner can easily perform a guitar performance that matches the rhythm.

Next, a method for causing a player to recognize a rhythm error will be described. FIG. 14 is a diagram for explaining a method of transmitting a rhythm error to a player. When the player presses the fifth fret switch and flicks the string switch, if the timing is earlier than the correct timing, the character “fast” is displayed near the fifth area, and the player further flicks. The timing is displayed as a triangle on the left side of the fret image part, depending on the degree of the advance, separated from the fret image part. If the played timing is later than the correct timing, the word “late” is displayed, and the timing played by the player is moved to the right side of the fret drawing area with a triangle mark and separated from the fret drawing area according to the degree of delay. To display. In the case shown in FIG.
Since the timing of pressing the fret switch was earlier, a triangle mark is displayed on the left side of the fifth fret image section. As described above, if the player can recognize whether the rhythm played by the player is fast or slow, the player can easily correct the rhythm with the next sound. In addition, by telling the player whether the rhythm is fast or slow, the player is presented with a path for improvement, and thus an ambition is created. Further, since the player can know "how fast or late", the correction width can be known, and the ambition can be further stimulated.

[Glue Evaluation Method] Next, a glue evaluation method will be described. In the prior art, when evaluating the good rhythm, only the degree of deviation from the absolute time axis with respect to the absolute time axis is evaluated. However, there is a thing called "slip" in music, and there is a limit in evaluating a player's sense of rhythm by a conventional evaluation method. For example, when three players play as shown in FIG. 15 with respect to an absolute rhythm serving as a reference, in the conventional evaluation method, (Player 1) = (Player 2) <(Player 3) become. However, the player 2 is carving a stable rhythm, and if there is only a deviation from the given absolute rhythm (such a performance is referred to as “backward”), if the player 2 wants to evaluate more musically, For example, (player 1) <(player 2) =
(Player 3) should be evaluated. In the present embodiment, in order to evaluate the “slip” portion, statistics of “how much deviation” is taken with respect to the absolute rhythm. "Nori" is evaluated by giving a bonus score so that the smaller the variance thereof, the higher the score. FIG. 16 is a diagram showing statistics of how much the music piece is shifted, and showing the result. The horizontal axis in FIG. 16 shows the timing shift, and the vertical axis shows the number of times. In the case shown in FIG. 3A, the performance is a so-called “pre-slit”, and a high score is given to such a player. In the case shown in FIG. 3B, the rhythm is taken at the correct timing, and a high score is given as in the conventional case. In the case shown in FIG. 3C, the performance is called so-called after gluing, and also in this case, a high score is given. In the case shown in FIG. 3D, the rhythm is taken out of pieces, and a low score is given to the player who has performed such a performance.

Next, a specific method of the glue evaluation will be described. In the game according to the present embodiment, the screen is switched in 1/60 second, and the input can be sensed every 1/60 second when the screen is switched. Also, depending on the tempo of the music, it is supposed to be in the rhythm of music from about +1/60 seconds to -1/60 seconds. If it is shifted more than this, it can be understood that the timing is shifted while listening to the sound. Therefore, in the present embodiment, A: when the rhythm is 1/60 second earlier, B: when the rhythm is just right, and C: when the rhythm is 1/60 second later, are determined to be performances on the rhythm. I decided to. Then, the numbers of sounds played at the respective timings are defined as NA, NB, and NC, respectively, as follows: (MAX (NA, NB, NC) -MIN (NA, NB, N
C)) The bonus point is calculated according to the formula of × (constant). A bonus point is calculated by multiplying a constant obtained by subtracting the minimum value of NA, NB and NC from the maximum value of NA, NB and NC, and the calculated bonus point is added to the score. With such a formula, the highest score is obtained when all inputs are at any of the timings A, B, and C, and the lowest score is obtained when all inputs are dispersed on average. Since it takes time to obtain the variance, in the present embodiment,
The above-described simple method is used to evaluate the performance that is usually performed at high speed. By evaluating the glue as in the present embodiment, the performances of “before gluing” and “after gluing” can also be evaluated as stable rhythms.

FIG. 17 is a flowchart of the glue evaluation. When a sound is played by the player (step S
1) In step S2, it is confirmed whether or not an accurate sound has been played at an accurate timing (within ± 1/60 second from the instructed timing). If an accurate sound is being played at an accurate timing, the process proceeds to step S3, and it is determined whether or not the timing shift is early. If the timing is not early, the process shifts to step S4 to determine whether the timing is late. If the timing is not late, the process proceeds to step S5, and the value of the counter NB for the case where the rhythm is just right is increased by one. In step S6, it is determined whether or not the performance has ended. If the performance has not ended, the process returns to step S1 to perform the next input process. If the performance is over, proceed to step S7,
Calculate the Nori evaluation bonus. If it is determined in step S3 that the timing is early, the process proceeds to step S3.
8, the value of the counter NA for the case where the rhythm is 1/60 seconds earlier is incremented by one, and the process proceeds to step S6. Then, the same processing as described above is performed. If it is determined in step S4 that the timing is late, the process proceeds to step S9, where the counter NC for 1/60 late is used.
Is incremented by one and the process proceeds to step S6. And
The same processing as described above is performed. In this way, the values of NA, NB, and NC at the time when one piece of music has been played are obtained, and the bonus point of the glue evaluation is calculated using the above equation.

[Tapping Simulation] Next, tapping simulation will be described. In actual guitar, there is a playing technique called tapping (light hand). This playing technique involves hammering and pulling with the right hand, and is basically hammering and pulling. Here, hammering refers to a technique in which the first sound is picked, and the next sound is produced by tapping another position on the same string with a finger and pressing it. Pulling refers to a technique in which when a finger is released from a string, the finger is "hooked" and released to make a sound.

In the game of the present embodiment, the tapping can be performed in a simulated manner. As a result, even a beginner can easily perform a difficult tapping technique. In the present embodiment, the performance is performed while distinguishing between the normal performance style and the tapping performance style. When shifting to the tapping style, a display to that effect (display indicating that the mode has shifted to the tapping mode) is displayed on the screen. The instruction of the tapping rendition is performed by displaying the characters or by changing the color of the corresponding area of the musical score object on the screen. When the tapping mode is not displayed, even if the player performs tapping, the performance becomes invalid.

FIG. 18 is a flowchart at the time of shifting to the tapping mode. In step S1, the screen indicates that the mode is the tapping mode, and shifts to the tapping mode. In step S2, it is determined whether any sound is being played. Even if the tapping mode is entered, if the player plays the string switch, the process goes to step S3 to reproduce the corresponding sound and returns to step S1. In the present embodiment, even if the mode shifts to the tapping mode,
The player can reproduce a normal sound by playing the string switch. If it is determined in step S2 that the string switch has not been hit, the process proceeds to step S4 to determine whether or not hammering has occurred. That is, when it is detected that the higher frequency fret switch has been pressed without releasing the finger from the currently pressed fret switch, the process proceeds to step S5, and sampling is performed for hammering of the pressed fret switch. Play the sound that was played. Then, the process returns to step S1. If it is determined in step S4 that the hammering is not occurring, the process proceeds to step S6 to determine whether or not pulling is performed. That is, if the finger is released from the currently pressed fret switch in a state where the lower fret switch is pressed than the currently pressed fret switch, it is determined that pulling is present, and the process proceeds to step S7. Plays sound sampled for fret switch pulling. If it is determined in step S6 that the pulling is not performed, the process proceeds to step S8 to determine whether the mute switch has been touched. If the mute switch is touched, step S9
Go to and stop the sound. If the user has not touched the mute switch, the process returns to step S1 to repeat the above-described processing. This process is performed only for a predetermined period, and after the period is over, the display of the tapping mode on the screen is erased, and the mode is returned to the normal mode to control the game.

[Operation of Embodiment] Next, a schematic operation of this embodiment will be described with reference to FIG. FIG. 19 is a schematic flowchart of the present embodiment. This flow is executed when a predetermined number of coins are inserted and the start button of the operation unit is pressed. Note that the player inputs sounds such as a bass and a lead guitar which are some parts of the music, and the sounds of the other parts are reproduced by the control unit 10. In step S1, it is determined whether the difficulty level of elementary or advanced is selected. When the elementary level is selected, the process proceeds to step S2, and it is determined which of the first elementary pieces has been selected. The player selects a desired song from 20 to 30 songs prepared in advance. In step S3, the music selected by the player is performed. The image of FIG. 9 is displayed on the screen of the display, and the musical score objects are scroll-displayed. If the player is good at performing, that is, if the player can perform well and the physical fitness meter remains by the time the first music is completed, the process proceeds to step S4 to determine whether the second music has been selected. Judge. In step S5, the performance of the second music is performed in the same manner as the first music. If the second song is also played well, the process moves to step S6, where the evaluation, ranking and ending are displayed. The evaluation is performed, for example, on a 100-point scale. At this time, bonus points based on the evaluation of the glue are added. In addition, this performance is compared with performances performed in the past, and the order of the player is displayed. Then, the end of the game is displayed on the screen. On the other hand, step S
If the performance meter becomes zero during the performance of step 3 or step S5, the process proceeds to step S6.
The same processing as above is performed, and the end of the game is displayed.

When the difficulty level is selected in step S1, when the advanced level is selected, the process proceeds to step S7 and the first level is selected.
Select the first song. In step S8, the first music piece is played. If the player can play well and the physical fitness meter remains, the process proceeds to step S9, and the second song is selected. In step S10, the selected second music piece is played. If the performance of the second music can be performed well, the process proceeds to step S11 to select the third music. In step S12, the third music piece is performed. If the performance of the third tune can be performed well, the process proceeds to step S6 to display the evaluation, ranking, and ending. Step S
At the end of the performance of the third piece of music at 12, it is determined whether or not the player has a superior performance, and the player with the superior performance is given a further opportunity to perform an extra performance. If your grade is excellent,
In step S13, a song for extra performance is selected. In step S14, the extra performance is performed, and the process proceeds to step S6 to display the evaluation, ranking, and ending. This game takes about 90 seconds per song, so the time required for one game is about 5 minutes.

[Effects of the Embodiment] According to the game apparatus of the present embodiment described above, even if the score cannot be read, the chord of the difficult guitar is not known, and the sense of rhythm is worse, it is displayed on the screen. The user can perform a guitar that matches the rhythm by playing while watching the score object or ball character. In addition, according to the present game device, the timing deviation when the player plays is displayed, so that the player can know whether his or her performance timing is too early or too late, and therefore even a beginner can easily perform. It is possible to perform a performance that matches the rhythm, and it is possible to further improve the performance technique.

Further, according to the game apparatus of the present embodiment, the so-called "previous paste" and "postpaste" are also evaluated as proper performances, so that the user can enjoy the game in a form closer to the actual performance. be able to.

[Other Embodiments] The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the invention. For example, in the above embodiment, the game device that plays the electronic guitar has been described. However, the game device of the present invention may be a game device that plays another musical instrument such as a piano, and is not a game.
