[1. First Embodiment]
FIG. 1 is an external view of a measurement system 1 according to the first embodiment of the present invention. The measuring system 1 includes a measuring device 11 that measures the positional relationship of keys that the player can simultaneously press with two fingers of one hand, and a keyboard as operation means for the player to give various instructions to the measuring device 11. 12, a display 13 for the measurement device 11 to notify the performer of various types of information by characters or figures, and a key for the player to input information on keys that can be used to play music and that can be played simultaneously. A keyboard instrument 14 is provided.

  The keyboard instrument 14 is provided with keys corresponding to the pitches of the sounds required to play the music, and when the key is pressed by the performer, any key is pressed at the timing of the key pressing and the key being released. Key generation data indicating whether or not the key has been pressed or released is generated, and the generated key input data is output to the measuring device 11. The keystroke data is composed of, for example, a combination of data indicating a key that has been pressed by a pitch corresponding to the key and data indicating either keystroke or key release.

  The keystroke data can also be used for the purpose of, for example, a sound generation instruction to the sound source device. In that case, the keystroke data may further include data indicating other than the pitch, such as the strength (speed) of the keystroke.

  FIG. 2 is a block diagram showing the configuration of the measuring device 11. The measurement device 11 is used by an interface unit 111 that transmits and receives data to and from an external device, a control unit 112 that controls components of the measurement device 11, and a program that instructs various processes by the control unit 112 and the control unit 112. A storage unit 113 that stores various data to be used and is used as a work area of the control unit 112 is provided.

  The measuring device 11 is in a state in which the position relation measurement is performed in the “OFF mode” in which the player does not measure the positional relationship of keys that can be pressed (hereinafter referred to as “positional measurement”). It has a certain “ON mode”. For example, the performer performs an operation of pressing a “measurement start” button on the screen displayed on the display 13 in accordance with an instruction from the measurement device 11 in the OFF mode, for example, by using the keyboard 12 to set the measurement device 11 in the ON mode. Switch to. Here, the measuring device 11 may be provided with a switch, a button, or the like as hardware for the performer to switch between the OFF mode and the ON mode.

  When the performer performs an operation of pressing the “measurement start” button, the keyboard 12 transmits a signal corresponding to the operation to the measurement device 11. When the control unit 112 of the measurement device 11 receives a signal indicating the pressing operation of the “measurement start” button from the keyboard 12, the control unit 112 displays a screen as shown in FIG. On the screen, for example, a message such as “Please press two keys separated from each other as much as possible with the thumb and little finger of the right hand” is displayed, and the performer uses the message to measure the positional relationship. Can know which finger should be used to stretch the finger in which direction to press the key.

  Here, the extension direction of the finger indicates in which direction on the keyboard the other finger extends with respect to a certain finger. When using the thumb and little finger of the right hand to strike two keys apart from each other at the same time, the little finger is to the right on the keyboard when the thumb is the reference, and the thumb is to the left on the keyboard when the little finger is the reference. Each will stretch in the direction. Here, the finger used for the positional relationship measurement by the performer and the direction of extension are not limited to those described above, and can be variously changed. Therefore, instead of the message shown in Fig. 3, for example, "Stretch the middle finger to the left as much as possible with the thumb of the right hand as the reference, and press the two keys at the same time. Or the like may be displayed on the display 13. In that case, the performer will extend the middle finger to the left on the keyboard when the thumb is the reference, and the thumb will extend to the right on the keyboard when the middle finger is the reference. In the crossed state, two keys are pressed simultaneously.

  In the measurement system 1, the finger to be used by the performer for keystrokes for measuring the positional relationship and the direction of extension thereof are determined in advance. Therefore, instead of displaying a message as shown in FIG. 3 on the display 13, A message with the same content may be notified to the performer by an instruction manual or the like.

  By the way, the control unit 112 of the measuring device 11 determines the positional relationship between the mode switching unit 1121 that performs switching processing between the OFF mode and the ON mode, and keys that the player can simultaneously press with two specific fingers of one hand. A positional relationship data generation unit 1122 that generates the positional relationship data shown. When the mode switching unit 1121 of the control unit 112 receives a signal indicating a pressing operation of the “measurement start” button from the keyboard 12, the mode switching unit 1121 sends an instruction to start positional relationship data generation processing to the positional relationship data generation unit 1122. In accordance with the start instruction, the positional relationship data generation unit 1122 starts monitoring the keystroke data transmitted from the keyboard instrument 14 via the interface unit 111.

  According to the message shown in FIG. 3, the performer spreads the thumb and little finger of the right hand to the left and right, and simultaneously presses any two keys that are as far apart as possible from the keys of the keyboard instrument 14. The keyboard instrument 14 transmits key hit data indicating the key hit by the performer to the measuring device 11. The interface unit 111 of the measuring device 11 includes a key-pressing data acquisition unit 1111 that receives key-pressing data transmitted from the keyboard instrument 14. The keystroke data acquisition unit 1111 delivers the received keystroke data to the positional relationship data generation unit 1122 of the control unit 112.

  After entering the ON mode, the positional relationship data generation unit 1122 receives the first keystroke data from the keystroke data acquisition unit 1111 and then receives subsequent keystroke data sent from the keystroke data acquisition unit 1111 for 3 seconds, for example. Thereafter, the following processing is performed without receiving the key hit data sent from the key hit data acquisition unit 1111.

  First, the positional relationship data generation unit 1122 identifies which key was pressed during which period based on the timing and content of the keystroke data received from the keystroke data acquisition unit 1111. The positional relationship data generation unit 1122 determines whether two keys have been pressed correctly at the same time based on the information specified as described above. Hereinafter, this determination is referred to as “keystroke success determination”.

  The keystroke success determination will be specifically described below. First, if the positional relationship data generation unit 1122 determines that only one key is pressed at the same time or that three or more keys are pressed at the same time, the player determines that the player has not correctly pressed two keys.

  Further, when the positional relationship data generation unit 1122 determines that two keys have been pressed at the same time, the positional relationship data generation unit 1122 determines whether or not the interval between the two keys is included in a predetermined range. This determination is to prevent erroneous positional relationship data from being generated when the performer simultaneously presses two keys using the left and right hands.

In the present invention, the interval between two keys on the keyboard is determined by the following rules.
(A) The interval between adjacent white and black keys is “1”.
(B) The interval between adjacent white keys is set to “2”.
Here, in (b), the interval is “2” regardless of whether or not there is a black key between adjacent white keys. For example, the interval between keys corresponding to the pitches of “D4” and “C5” (hereinafter referred to as keys “D4” and “C5”) is “12”, and the keys “D4” and “F #” The interval of “4” is “5”.

  When the interval between two keys simultaneously pressed by the performer is not included in, for example, “6 to 17” which is a predetermined range, the positional relationship data generation unit 1122 correctly sets the right thumb and pinky It is determined that the key was not pressed. The predetermined range “6 to 17” indicates a range of an interval between two keys pressed by a standard performer, and the measuring apparatus 11 stores data indicating this range in the processing logic of the positional relationship data generation unit 1122 in advance. You may memorize | store in the form of incorporating, You may memorize | store in the memory | storage part 113 as standard positional relationship data.

  As described above, the positional relationship data generation unit 1122 determines that two keys have not been correctly pressed, that is, if only one key has been pressed, if three or more keys have been pressed simultaneously, and If the distance between the two keys that were pressed at the same time was out of the predetermined range, the display 13 shows, for example, “The key was not correctly pressed. Again, with the thumb and little finger of the right hand, “Please play the keys at the same time.” Is displayed, and the above-described keying data acquisition process from the keying data acquisition unit 1111 and the keying success determination are repeated.

  On the other hand, if the positional relationship data generating unit 1122 determines that two keys are simultaneously pressed and the interval between the keys is included in a predetermined range, it determines that the player has correctly pressed the key. The above is the keystroke success determination.

If the positional relationship data generation unit 1122 determines that the correct key has been pressed in the key pressing success determination, for example, the positional relationship data generation unit 1122 performs the calculations shown in the following (Expression 1) to (Expression 40).

Here, R _{1 to} R ₅ represent the thumb to the little finger of the right hand, respectively, and L _{1 to} L ₅ represent the thumb to the little finger of the left hand, respectively. (R _i , R _j ) is related to the right hand when the finger indicated by i is extended to the right as much as possible with reference to the finger indicated by _i , and (L _i , L _j ) is related to the left hand. , I is the estimated position of the key that can be correctly pressed simultaneously when the finger indicated by j is extended to the left as much as possible with the finger indicated by i as a reference. The numerical value indicating the position of the key thus estimated is a numerical value whose absolute value indicates the interval between the two keys described above. If the sign is positive, the position and sign in the right direction from the reference key are If it is negative, it indicates the position to the left of the reference key.

For example, (R ₁ , R ₂ ) is based on the thumb of the right hand, and when the index finger of the right hand is opened to the right as much as possible, the estimated value of the interval between two keys that can be pressed simultaneously by the thumb of the right hand and the index finger Show. Also, (L ₃ , L ₅ ) is an estimate of the interval between two keys that can be simultaneously pressed with the middle finger and little finger of the left hand when the left little finger is opened to the left as much as possible with the middle finger of the left hand as a reference. Show. As described above, since the arrangement of the fingers is symmetrical between the right hand and the left hand, the extending directions are opposite to each other. Further, the _{(r 1, r 5) r} 1 and r ₅ each represent a right thumb and little finger in, (r _1, r ₅₎ is correct keying in keystrokes successful determination the positional relationship data generation unit 1122 has been performed This is an actual measurement value indicating the interval between two keys in the case of determination.

As shown in (Equation 4), in this embodiment, the measured values (r ₁ , r ₅ ) are used as estimated values (R ₁ , R ₅ ) of key intervals that can be simultaneously pressed with the thumb and little finger of the right hand. ₅ ) is used as is.

Further, a _{Ri, Rj} or a _{Li, Lj} is a numerical value indicating a key interval at which a standard performer can simultaneously press keys with a combination of fingers (R _i , R _j ) or (L _i , L _j ). Is divided by a numerical value indicating a key interval at which a standard performer can simultaneously press the key combination (R ₁ , R ₅ ). For example, a standard performer has a finger combination of (R ₂ , R ₄ ) with a key interval of “7”, and a standard performer has a finger combination of (R ₁ , R ₅ ). When the interval between keys that can be pressed is “15”, a _{R2, R4} = 7 ÷ 15 = about 0.47. a _{Ri, Rj} and a _{Li, Lj} may be stored in advance by the measuring device 11 in a form incorporated in the processing logic of the positional relationship data generation unit 1122 or stored in the storage unit 113 as a coefficient data group. The relation data generation unit 1122 may be used. In addition, instead of the key interval (integer value) that a standard player can strike with a specific finger combination, the interval between fingers when the standard player expands a specific finger as much as possible, A numerical value (a decimal value is also acceptable) expressed as 1 between the adjacent white key and black key may be used.

  Round {} is a function that truncates the decimal point of the absolute value of the numerical value while maintaining the sign of the numerical value in {}. However, Round {} rounds up the decimal value of the absolute value while maintaining the sign of the numerical value in {} only when it becomes 0 when the decimal value of the absolute value of the value in {} is rounded down. . For example, Round {2.6} = 2 and Round {−1.3} = − 1. In addition, Round {−0.3} = − 1 and Round {0.2} = 1. The reason why the value of Round {} does not take 0 is that the same key is not simultaneously pressed with two different fingers.

  The positional relationship data generation unit 1122 creates a numerical table as illustrated in FIG. 4 using the values calculated by (Expression 1) to (Expression 40). In the numerical table of FIG. 4, a row indicates a reference finger and a column indicates another finger. In the numerical table of FIG. 4, “0” is stored in the column indicating the same finger in the same row and column because the keys that can be simultaneously pressed with the same finger are the same.

FIG. 4A is a numerical table showing the intervals of keys that can be simultaneously pressed by extending the fingers shown in the column in the right direction as much as possible with reference to the fingers shown in the row with respect to the right hand. For example, (R ₁ , R ₂ ) calculated by (Equation 1) is stored in the first row and second column of FIG. 4A, and the value is “9”. FIG. 5 shows an example of a keystroke with two fingers indicated by the numerical values in the numerical table of FIG. FIG. 5A shows the state of keystroke indicated by (R ₁ , R ₂ ) = 9 in FIG.

For example, (R ₃ , R ₁ ) calculated by (Equation 12) is stored in the third row and first column of FIG. 4A, and the value is “3”. FIG. 5B shows a state of keystroke indicated by (R ₃ , R ₁ ) = 3. As shown in FIG. 5B, with respect to the right hand, in the combination of fingers indicated by (i, j), when the finger indicated by i spreads the hand in a normal state rather than the finger indicated by j. If they are located to the right and the value of (i, j) is positive, their fingers will cross each other.

For example, (R ₄ , R ₃ ) calculated by (Equation 18) is stored in the fourth row and third column of FIG. 4A, and the value is “−1”. FIG. 5C shows a state of keystroke indicated by (R ₄ , R ₃ ) = − 1. As shown in FIG. 5C, in the combination of fingers indicated by (i, j), the position of the key that can be pressed by the finger indicated by i is the position of the key that can be pressed by the finger indicated by j. If it is located to the right of (i, j), the value of (i, j) is negative.

On the other hand, FIG. 4B is a numerical table showing the interval of keys that can be simultaneously pressed by extending the fingers indicated by the columns in the left direction as much as possible with reference to the fingers indicated by the rows with respect to the left hand. For example, (L ₁ , L ₃ ) calculated by (Equation 22) is stored in the first row and third column of FIG. 4B, and the value is “−10”. FIG. 5D shows a state of keystroke indicated by (L ₁ , L ₃ ) = − 10.

For example, (L ₄ , L ₁ ) calculated by (Expression 33) is stored in the fourth row and first column of FIG. 4B, and the value is “−2”. FIG. 5E shows a state of keystroke indicated by (L ₄ , L ₁ ) = − 2. As shown in FIG. 5E, for the left hand, in the combination of fingers indicated by (i, j), when the finger indicated by i spreads the hand in a normal state than the finger indicated by j. If they are located on the left and the value of (i, j) is negative, their fingers will cross each other.

For example, (L ₅ , L ₄ ) calculated by (Equation 40) is stored in the fifth row and fourth column of FIG. 4B, and the value is “1”. FIG. 5 (f) shows a state of keystroke indicated by (L ₅ , L ₄ ) = 1.

  When the positional relationship data generation unit 1122 generates the numerical table as illustrated in FIG. 4, the positional relationship data generation unit 1122 generates a numerical table in which the matrix of the generated numerical table is replaced and the sign of each numerical value is replaced. FIGS. 6A and 6B show numerical tables generated by the positional relationship data generation unit 1122 based on FIGS. 4A and 4B, respectively. FIG. 6A is a numerical table showing the interval of keys that can be simultaneously pressed by extending the fingers indicated by the column in the left direction as much as possible with respect to the fingers indicated by the row with respect to the right hand. FIG. 6B is a numerical table showing the intervals of keys that can be simultaneously pressed by extending the fingers indicated by the columns in the right direction as much as possible with respect to the fingers indicated by the rows with respect to the left hand.

  When the positional relationship data generation unit 1122 generates the numerical table illustrated in FIGS. 4 and 6, the positional relationship data generation unit 1122 stores the generated numerical table in the storage unit 113 as the positional relationship data 1131. As described above, the positional relationship data 1131 generated by the measuring device 11 is, for example, a device that displays and corrects musical score data including fingering information in accordance with the player's finger stretching ability, or a player's finger movement. Is used in a device or the like for displaying 3DCG.

FIG. 7 shows an example of using the positional relationship data 1131 as an apparatus for correcting and displaying musical score data including fingering information according to the player's finger expansion ability (hereinafter referred to as “musical score data correcting apparatus”). It is a figure for demonstrating how the positional relationship data 1131 are used. FIG. 7A shows chords and fingerings based on musical score data stored in advance in the musical score data correcting apparatus, and FIG. 7B shows chords and fingerings based on musical score data corrected by the musical score data correcting apparatus. Show. However, it is assumed that the positional relationship data 1131 used by the musical score data correcting apparatus has the contents illustrated in FIGS. 4 and 6. The numerical value shown on the left side of the note group in FIG. 7 indicates the interval of the key corresponding to the note group, and the symbol such as R ₁ shown on the right side of the note group indicates the finger to which the key corresponding to the note should be pressed.

To perform the chord shown in FIG. 7 (a), the performer (a) expands the right thumb and right index finger by a distance “7”, and (b) further increases the right index finger and right hand little finger by a distance “9”. It is necessary to expand the keystrokes. Therefore, the performer needs to expand (c) the right thumb and the right little finger by the interval “16”. On the other hand, according to FIG. 4 (a) showing the player's finger extension ability when the other finger is extended to the right from the reference finger with respect to the right hand, (R ₁ , R ₂ ) = 9 and ( The condition (a) is satisfied and (R ₂ , R ₅ ) = 10 and the condition (b) is satisfied, but (R ₁ , R ₅ ) = 15 and the condition (c) is not satisfied.

Therefore, the musical score data correcting device determines that it is difficult for the player to correctly play the chord shown in FIG. 7A according to the ability of the player's finger to expand as indicated by the positional relationship data 1131. To do. In that case, the musical score data correcting apparatus omits relatively unimportant sounds, changes the development, or substitutes alternative chords in the chord shown in FIG. The chord shown in FIG. 7A is replaced with a chord that can be played by the finger stretching ability indicated by 1131. In this case, as shown in FIG. 7B, the musical score data correcting apparatus can be performed by the performer by omitting the F # sound and changing the fingering of the B # sound from R ₂ to R _1. The score is displayed.

  By the way, the measuring device 11 may have a function of a device that uses the positional relationship data 1131 such as a musical score data correcting device. In that case, when the measuring apparatus 11 performs processing that requires the positional relationship data 1131, the positional relationship data 1131 is read from the storage unit 113 and used. On the other hand, a device using the positional relationship data 1131 such as a musical score data correcting device may be different from the measuring device 11. The interface unit 111 of the measurement apparatus 11 includes a positional relationship data output unit 1112 that transmits positional relationship data 1131 to an external device. That is, an external device that requires the positional relationship data 1131 can receive the positional relationship data 1131 from the positional relationship data output unit 1112 of the measuring device 11 and use it.

  As described above, according to the measurement system 1, the performer measures his / her finger stretching ability, that is, in this case, the positional relationship of keys that can be simultaneously pressed by two fingers of one hand. Data indicating the results can be generated. In that case, the performer only needs to press the keys on the keyboard, and no effort or time is required. In addition, by using a keyboard (or a keyboard having the same size) that is actually used for performance, the performer can obtain data that accurately indicates whether or not keys can be played using the keyboard.

  In the above-described embodiment, for example, the right thumb and the little finger are stretched in the right direction with respect to the thumb and the key is pressed. Is automatically estimated. Therefore, it is possible to reduce the time and effort of the performer as compared with the case of repeating the keystroke for each combination of two arbitrary fingers and the extending direction.

  By the way, in the above embodiment, the positional relationship data according to all (Equation 1) to (Equation 40) regardless of the size of the keyed key when the player's right hand thumb and little finger are expanded. It has been described that 1131 is generated. This is based on the assumption that the ratio of the distance when the two fingers are extended is the same regardless of the size of the player's hand. I mean.

  Therefore, instead of the measurement apparatus 11 generating the positional relationship data 1131 by calculation according to (Equation 1) to (Equation 40), a plurality of standard items corresponding to each of the finger expansion capabilities actually measured in the storage unit 113 are used. The positional relationship data 1131 may be stored, and the positional relationship data 1131 may be selected according to the actually measured finger stretching ability. Further, in addition to the finger stretching ability measured by the measuring device 11, a plurality of standard positional relationship data corresponding to attributes such as the performer's gender and age are stored in the storage unit 113 in advance and measured. A suitable one may be selected from standard positional relationship data based on the finger stretching ability and attribute information such as sex and age input by the performer. FIG. 8 is a diagram schematically showing the configuration of the positional relationship data group stored in advance in the storage unit 113 in such a modified embodiment.

  When the measurement device 11 stores a positional relationship data group as shown in FIG. 8 in advance, the measurement device 11 only needs to select suitable positional relationship data from the positional relationship data group, and only the processing speed is increased. Instead, more accurate estimation of the finger stretching ability is performed according to the hand size and the like.

  Further, in the above embodiment, it has been described that the performer only needs to press the key once. This means that the player's finger stretching ability is actually measured for only one set of fingers, and all other stretching ability is estimated. Therefore, instead of calculating the estimated value according to (Equation 1) to (Equation 40), the measuring device 11 asks the player “to simultaneously press two keys separated as much as possible with the thumb and middle finger of the right hand. ”,“ Use the thumb and ring finger of the right hand to strike two keys that are as far apart as possible from each other at the same time. ” Each column of the numerical table as shown in FIG. 4 may be sequentially filled with actually measured values based on keystroke data indicating keystrokes made by the performer in response to the notification. The positional relationship data 1131 obtained in this way represents the player's finger stretching ability more accurately than that obtained by estimation.

  As in the above modification, in order to generate the positional relationship data 1131, if the player performs keystrokes for all combinations of fingers and extension directions, the player needs to repeat the keystrokes 40 times. It will take a lot of time and effort. Therefore, instead of performing actual measurement for all combinations, the measurement apparatus 11 may be configured to generate the positional relationship data 1131 by estimating the remaining values based on a plurality of actual measurement values.

  In that case, the measuring apparatus 11 stores information on the combination of fingers and the extension direction, which are considered to show the performer's finger extension ability, in advance as keystroke instruction data. In accordance with the keying instruction data, the measuring device 11 asks the performer to “key two keys separated as much as possible with the thumb and little finger of the right hand simultaneously”, “two as far apart as possible with the middle finger and ring finger of the right hand. Strike two keys at the same time. ”,“ Stretch the middle finger to the left as much as possible with the thumb of the right hand as a reference, and strike the two keys at the same time. In order, the player is notified of the finger to be used for keystroke and the extension direction.

  The measuring device 11 is based on keystroke data indicating keystrokes performed by the performer in response to these notifications, and calculates a numerical value indicating the finger combination indicated by the keystroke instruction data and the ability of the player's finger to expand according to the extension direction. Acquired as an actual measurement value. Further, the measuring device 11 estimates the position of the player by estimating the value according to the combination of fingers not used for the player's keystroke and the extension direction according to a predetermined calculation formula based on the actually measured value thus obtained. Relationship data 1131 is generated. Further, instead of estimating the numerical value not actually measured by the calculation formula and completing the positional relationship data 1131, the measuring device 11 stores and acquires a plurality of standard positional relationship data 1131 in the storage unit 113 in advance. The positional relationship data 1131 that best matches the actual measurement value may be selected from the stored positional relationship data 1131 group.

  When the above-described modification is added to the first embodiment, a performance with sufficient accuracy can be achieved without requiring labor and time as compared with the case where the performer performs keystrokes with combinations of all fingers and extension directions. Data indicating the ability of the person's finger to stretch is obtained.

  Further, as described above, instead of notifying the player of the combination of fingers to be pressed and the extending direction, the measuring device 11 does not notify the player of the combination of fingers to be pressed and two keys to be pressed (to be pressed). Alternatively, the interval between these keys may be notified. In that case, the measuring device 11 previously stores in the storage unit 113 a key that can be pressed by a standard player according to each of the finger combinations and extending directions that are considered to show the player's finger stretching ability. The information shown is stored as keystroke instruction data. In accordance with the keying instruction data, the measuring device 11 gives a notification to the performer such as “Please simultaneously press C4 with the thumb of the right hand and B4 with the little finger of the right hand”, and the keystroke performed by the player in response to the notification. It is determined whether or not correct key pressing has been performed on the basis of key pressing data indicative of

  When the measuring device 11 determines that the keystroke of the notified key has not been correctly performed by the performer, the player “struck C4 with the thumb of the right hand and A # 4 with the little finger of the right hand simultaneously. As in the case of "", a new key pressing instruction is given by reducing the degree of finger extension compared to the key pressing previously instructed. On the other hand, if the measuring device 11 determines that the player has correctly pressed the key that has been notified, the player should “press C4 with the thumb of the right hand and C5 with the little finger of the right hand simultaneously”. As described above, a new key press is instructed by increasing the degree of finger extension compared to the key press previously instructed. As described above, the measuring device 11 measures the player's finger stretching ability by repeating the keystroke instruction to the player and determining whether or not the correct keystroke has been performed. The measurement device 11 may repeat such measurement for all finger combinations and extension directions, or performs measurement only for the finger combinations and extension directions that significantly show finger extension capability, and other finger combinations. The extension direction may be estimated.

  In the above embodiment, the measurement system 1 is described as measuring the interval of keys that can be simultaneously pressed by the performer using two fingers of one hand. It is also possible to further measure the interval between keys that can be simultaneously pressed using the right and left fingers. In that case, the measuring device 11 gives a keystroke instruction to the performer, for example, “Please strike two keys separated as much as possible with the little finger of the right hand and the little finger of the left hand at the same time” and the player has pressed the key. Measure the key interval. Based on the data indicating the key interval thus measured, for example, the musical score data correction device instructs a player who has a small body to simultaneously press keys on a keyboard that is too far to reach even if both hands are extended. The musical score data can be modified to indicate a musical score that can be played by the performer.

  By the way, the measurement device 11 may be realized by dedicated hardware, or may be realized by causing a general-purpose computer to execute processing according to an application program. When the measuring apparatus 11 is realized by a general-purpose computer, each component of the control unit 112 performs processing according to each module included in the application program simultaneously in parallel by a CPU (Central Processing Unit) included in the general-purpose computer. This is realized as a function of a general-purpose computer.

[2. Second Embodiment]
Hereinafter, the configuration and operation of the measurement system 2 according to the second embodiment of the present invention will be described. In the measurement system 2, unlike the measurement system 1, the keyboard instrument 14 detects the finger used by the performer to press a specific key, and based on the finger data indicating the detection result, the finger of the performer is detected. The positional relationship data indicating the expansion capability is generated. Since the configuration and operation of the measurement system 2 are the same as those of the measurement system 1 in many respects, only the points where the measurement system 2 is different from the measurement system 1 will be described below. In the drawings referred to below, the same reference numerals are used for the same or corresponding components as those in the measurement system 1.

  The appearance of the measurement system 2 is the same as that of the measurement system 1 shown in FIG. However, as described above, the keyboard instrument 14 of the measurement system 2 has a function of generating finger data in addition to the generation of keystroke data. Therefore, for example, each key included in the keyboard instrument 14 is provided with an RFID (Radio Frequency Identification) reader. The RFID reader provided in the keyboard instrument 14 receives the radio wave emitted from the RFID tag, and specifies the ID indicated by the received radio wave.

  On the other hand, in the measurement system 2, the performer performs keystrokes by attaching RFID tags that emit radio waves indicating different IDs to the fingers. Each RFID tag generates power using radio waves emitted from an RFID reader provided on the keyboard instrument 14, and uses an electric power obtained by the power generation to store an ID stored in a built-in IC (I integrated Circuit) in advance. The indicated radio wave is emitted to the RFID reader. Therefore, the RFID reader provided in each key receives radio waves from each of the ten RFID tags attached to the ten fingers of both hands of the performer. The RFID reader selects the tenest radio wave having the highest intensity, and specifies the ID indicated by the selected radio wave. The ID specified in this way indicates the ID of the RFID tag closest to the key provided with the RFID reader, that is, information that specifies the player's finger closest to the key.

The keyboard instrument 14 in the measurement system 2 generates keystroke data indicating the key that has been pressed when the player performs the keystroke, and the ID specified by the RFID reader provided on the key that is keyed at the timing of the keystroke. Data, i.e., finger data, is generated, and the keystroke data and finger data are associated with each other and transmitted to the measuring device 11. The finger data is data such as “R ₁ ” indicating the thumb of the right hand, for example.

  Various methods can be conceived for the keyboard instrument 14 to identify the finger used for the keystroke in addition to the method using the RFID tag. For example, when an electrode provided on a sensor attached to the fingertip of a performer and an electrode provided on a key come into contact with each other, current is detected to detect which key is pressed by the sensor attached to which finger. You may make it do.

  FIG. 9 is a block diagram illustrating a configuration of the measurement device 11 in the measurement system 2. In the measurement system 2, the interface unit 111 of the measurement device 11 includes a finger data acquisition unit 1113 that receives finger data transmitted from the keyboard instrument 14. In addition, the storage unit 113 of the measuring device 11 is extremely concerned with finger combinations and keystroke instruction data 1132 indicating the extension direction of the performer's fingers and the specific two fingers. A player with high extension ability was measured with respect to standard position relation data 1133 indicating the range of key positions that can be pressed with the other finger on the basis of one person, and various players with different hand sizes, ages, genders, etc. A sample positional relationship data group 1134 which is a collection of standard samples of positional relationship data obtained by statistically processing the positional relationship data is stored in advance.

  FIG. 10 is a diagram illustrating the contents of the keystroke instruction data 1132. The keystroke instruction data 1132 includes a plurality of data consisting of a “finger combination” field and an “extension direction” field.

  FIG. 11 is a diagram illustrating the contents of the standard positional relationship data 1133. The format of the standard positional relationship data 1133 is the same as the data shown in FIG. 4, but is data relating to a player (which may be a virtual player) with extremely high finger stretching ability. As in the case of the measurement system 1, the standard positional relationship data 1133 is used as a reference for error processing when, for example, the player performs keystrokes using the fingers of the left and right hands. The standard positional relationship data 1133 is also used to determine in which direction the two fingers that have pressed the key are extended. Processing related to the determination will be described later.

  FIG. 12 is a diagram schematically showing the configuration of the sample positional relationship data group 1134. Each sample positional relationship data included in the sample positional relationship data group 1134 is standard positional relationship data of performers with different hand sizes, genders, ages, and the like.

  Hereinafter, the operation of the measurement system 2 in the case where the positional relationship data 1131 indicating the finger stretching ability of the player who is the user is generated in the measurement system 2 will be described. First, in the ON mode, the measuring device 11 displays the screen shown in FIG. 13 on the display 13 based on the keystroke instruction data 1132. The screen shown in FIG. 13 includes a table having a “finger combination” field, an “extension direction” field, and an “unpressed key” field (hereinafter referred to as “keystroke instruction table”). Immediately after switching to the ON mode, all the values in the “unpressed key” column of the key input instruction table are “Yes”.

  In the ON mode, the performer puts the RFID tag on each finger, and then performs the keystroke indicated by an arbitrary data row in which the “unkeyed” column is “Yes” in the keystroke instruction table. When a key is pressed by the performer, the keyboard instrument 14 transmits to the measuring device 11 key pressing data indicating the key pressed and finger data indicating the key pressed. The keystroke data acquisition unit 1111 and the finger data acquisition unit 1113 provided in the interface unit 111 of the measurement apparatus 11 receive the keystroke data and finger data from the keyboard instrument 14, respectively, and temporarily associate them with the storage unit 113. Remember.

  The measuring device 11 can specify the key that was simultaneously keyed and the finger used for the keystroke, based on the received keystroke data and finger data. As in the measurement system 1, the positional relationship data generation unit 1122 of the measuring device 11 was not correctly keyed when only one key was keyed or when three or more keys were keyed simultaneously. Judge that it is.

On the other hand, when two keys are pressed simultaneously, the positional relationship data generation unit 1122 extracts, from the standard positional relationship data 1133 (see FIG. 11), a numerical value corresponding to the combination of fingers used for keying those keys. . For example, when the key is pressed with the right thumb (R ₁ ) and the middle finger (R ₃ ), (R ₁ , R ₃ ) = 13 and (R ₃ , R ₁ ) = 5 are extracted by the positional relationship data generation unit 1122. Is done.

The positional relationship data generation unit 1122 replaces the reference finger and the other finger for the extracted numerical value whose reference finger number is larger than the other finger number, and changes the sign of the numerical value. Invert. For example, when the positional relationship data generation unit 1122 extracts (R ₁ , R ₃ ) = 13 and (R ₃ , R ₁ ) = 5, based on (R ₃ , R ₁ ) = 5, (R ₁ , R ₃ ) =-5 is generated. Here, (R ₁ , R ₃ ) = 13 is obtained from a key in which the middle finger of the right hand is pressed with the thumb of the right hand when the performer extends the middle finger of the right hand as much as possible in the right direction with reference to the thumb of the right hand. Indicates that it is possible to strike a key separated by “13” to the right, whereas (R ₁ , R ₃ ) = − 5 indicates that the performer can move the middle finger of the right hand to the left with the thumb of the right hand as a reference. It shows that when the middle finger of the right hand is stretched in the direction as much as possible, it is possible to strike a key that is separated by “−5” (ie, “5” on the left) to the right of the key that is tapped by the thumb of the right hand. ing.

Subsequently, the positional relationship data generation unit 1122 uses (R ₁ , R ₃ ) = 13 and (R ₁ , R ₃ ) = − 5 that specify the numerical values indicating the positional relationship of the keys that have been pressed as described above. It is determined whether or not it is within the indicated range, that is, the range of -5 to 13. When the numerical value indicating the positional relationship of the key that has been pressed is out of the range of −5 to 13, the positional relationship data generation unit 1122 determines that the key has not been correctly input.

When the numerical value indicating the positional relationship of the key that has been pressed is in the range of −5 to 13, the positional relationship data generation unit 1122 continues to determine whether the numerical value indicating the positional relationship of the key that has been pressed is any of −5 and 13 To determine whether it is closer. For example, when the player hits C4 with the thumb of the right hand and A4 with the middle finger, the positional relationship between these keys is 10, which is closer to (R ₁ , R ₃ ) = 13. In this case, the positional relationship data generation unit 1122 determines that the middle finger is expanded rightward with the thumb as a reference. On the other hand, when C4 is pressed with the middle finger of the right hand and E4 is pressed with the thumb by the performer, the positional relationship of these keys is −4, based on E4 pressed with the thumb, and (R ₁ , R ₃ ) = Closer to -5. In this case, the positional relationship data generation unit 1122 determines that the middle finger is expanded leftward with respect to the thumb. Note that this is synonymous with the thumb extending rightward with respect to the middle finger.

  When the positional relationship data generation unit 1122 specifies the extension direction of the finger when the key is correctly pressed as described above, the position of the key pressed in the data indicating the combination and extension direction of the fingers used for key pressing. A numerical value indicating the relationship is associated and temporarily stored in the storage unit 113. At the same time, the positional relationship data generation unit 1122 changes the value of the “unkeyed” column of the data row corresponding to the keystroke by the performer from “Yes” to “No” among the data rows included in the keystroke instruction table on the screen of FIG. The display of the data line is moved to the end of the keystroke instruction table, for example. As a result, the performer can easily know the details of the keystroke to be performed.

  Note that if the performer accidentally performs keystrokes with combinations of fingers not shown in the keystroke instruction table, the positional relationship data generation unit 1122 may ignore the keystrokes, or similar to what is included in the keystroke instruction table. The position relation data described below may be used for selection. Also, if the performer has already pressed a key in the combination and extension direction of the finger whose “Unrecorded Key” field is “No”, the positional relationship data generation unit 1122 may ignore the keystroke, or already The numerical value temporarily stored in the storage unit 113 may be compared with the numerical value indicating the positional relationship of the key generated by the newly performed keystroke, and the one having a higher degree of expansion may be adopted. . Further, ON / OFF of the “overwrite mode” can be switched according to the player's operation. When the “overwrite mode” is ON, a combination of fingers whose “no key pressed” column is already “No” When a key is pressed in the extension direction, a numerical value already stored may be overwritten and updated with a numerical value generated by a newly performed key pressing.

  As described above, when the positional relationship data generation unit 1122 acquires the numerical values indicating the key positional relationships related to all keystrokes specified by the standard positional relationship data 1133, the positional relationship data generation unit 1122 includes the sample positional relationship data group 1134 (see FIG. 12). Then, the sample positional relationship data that most closely matches the numerical value of the player's keystrokes temporarily stored in the storage unit 113 is selected. For example, the positional relationship data generation unit 1122 calculates the square sum of the difference between the corresponding numerical values between the numerical value of the player's keystroke and the numerical value of the sample positional relationship data, and obtains the sample positional relationship data that minimizes the numerical value. The sample position relation data group 1134 is selected. However, the index indicating the degree of approximation of the data is not limited to the sum of squares of the differences, and various other types are conceivable, such as using the sum of absolute values of the differences.

  The positional relationship data generation unit 1122 stores the sample positional relationship data selected as described above in the storage unit 113 as positional relationship data 1131 indicating the player's finger stretching ability. Moreover, the measuring device 11 transmits the positional relationship data 1131 to the external device via the positional relationship data output unit 1112 of the interface unit 111 as necessary. How the positional relationship data 1131 is used is the same as that described in the measurement system 1.

  As described above, as a result of using finger data in the measurement system 2, the performer is required to perform keystrokes by a combination of fingers according to the instructions shown on the display 13 in generating the positional relationship data 1131. Absent. In the measurement system 2, as a result of the positional relationship data generation unit 1122 automatically specifying the finger extension direction based on the standard positional relationship data 1133, the player can move in the desired direction when generating the positional relationship data 1131. Keys can be pressed by extending a finger.

  By the way, in the measurement system 2 described above, the finger combination and the extension direction are displayed on the display 13 in accordance with the key input instruction data 1132, but the measurement device 11 uses the combination and extension of the fingers to be used for key pressing to the performer. Without indicating the direction, for example, a necessary number of numerical values based on key combinations based on arbitrary finger combinations and extension directions are collected, and sample positional relationship data is selected from the sample positional relationship data group 1134 based on the collected numerical values. May be. According to the measurement system 2 thus modified, the performer can freely perform keystrokes and is simpler.

  Further, the positional relationship data generation unit 1122 generates a predetermined calculation formula in the same manner as in the first embodiment, instead of generating the positional relationship data 1131 by selecting appropriate sample positional relationship data from the sample positional relationship data group 1134. The positional relationship data 1131 may be generated by estimating a numerical value that has not been actually measured according to the above.

  Further, the measurement system 2 may be modified to generate positional relationship data 1131 indicating not only the positional relationship of two fingers but also the positional relationship of keys that can be pressed by the performer for three or more fingers. At this time, instead of simply using the positional relationship indicating the key interval, for example, the positional relationship data considering the positions of the white key and the black key may be generated as in (C4, F # 4, G5). Good. In this case, the measuring device 11 sequentially stores data indicating the key pressed by the performer and the finger used for the key generation, thereby generating positional relationship data 1131 indicating the positional relationship of keys that can be pressed by the performer. To do. For example, the musical score data correcting device determines whether or not the fingering indicated by the musical score data is possible by the performer based on the positional relationship data 1131 generated as described above, and if an impossible fingering is found. Change to a possible alternative fingering.

  Also, in the measurement system 2, as described in the measurement system 1, it is possible to measure the interval between keys that can be pressed simultaneously using the fingers of the player's right hand and left finger. In this case, for example, when the measuring device 11 receives keying data and finger data indicating simultaneous keying by the little finger of the right hand and the little finger of the left hand from the keyboard instrument 14, the data indicating the key interval calculated based on the data is played. It is generated as positional relationship data 1131 indicating the interval between keys that can be simultaneously pressed using both hands. Using the positional relationship data 1131 generated as described above, for example, the score data correction device can generate score data according to the player's ability to extend both hands.

  In the measurement system 2 described above, the musical instrument used by the performer is a keyboard musical instrument. However, the present invention can be applied to other musical instruments such as a stringed musical instrument. For example, an RFID reader is provided at the intersection of a guitar string and a fret, and a player wears an RFID tag similar to that in the measurement system 2 to determine which position is held by which finger. It becomes possible to specify. Furthermore, by providing a sensor for detecting string vibration in the bridge portion of the guitar, it is possible to identify the repelled string and its timing. Based on the information specified by these sensors, the position that can be correctly pressed by the performer may be specified by the measuring device 11 in the same manner as described above, and the positional relationship data indicating the result may be generated.
