By the way, in sports performed by multiple players, such as soccer, volleyball, baseball, car racing, yacht racing, etc., the result of the competition depends on how well the play that interferes with enemy players or helps friendly players can be performed. Pass or fail is affected. Players of this type of sport must know the status of themselves and other players that change from moment to moment, and must determine the timing and direction of exercise such as runs and jumps. Even if the player's performance strength, accuracy, and agility are excellent, if the player's state is not accurately grasped and those decisions are made or the timing of the decision itself is delayed, As a team, good results cannot be obtained.
However, many of the technologies that have been proposed so far are limited to assessing whether the player is moving his body according to his model, and the ability to judge the exercise that best matches the state of each player including himself It was not enough to meet the desire to increase
The present invention has been devised under such a background, and an object of the present invention is to provide a mechanism for supporting improvement of the situation determination ability of each player who performs sports.

The present invention provides a technical means for feeding back a support target player to the best exercise by feeding back to the support target player aspects such as cooperative play performed by a plurality of players.
In a preferred aspect, the exercise support apparatus according to the present invention includes state detection means for detecting the state of each of the plurality of players, and at least one of the plurality of players based on the states of the plurality of players detected by the state detection means. A guide sound providing means for generating a guide sound for causing the support target player that is a part to perform an optimal exercise and providing the support target player with the guide sound is provided.

  According to this aspect, the guidance sound of the optimal exercise generated based on the state of each player is provided to the support target player. Therefore, the support target player listens to the guidance sound, so that the status of each of the plurality of players, specifically, the friendly player who cooperates with the player is in an advantageous state, It can be easily grasped that the enemy players to be disturbed are in a disadvantaged state or will soon be in such a state without looking directly at those players. And with the assistance of such guidance sounds, we can improve the situation judgment ability necessary for sports by judging the timing of the start of the exercise that we perform and by repeating the training to judge the direction of doing the exercise. Can be increased.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
A first embodiment of the present invention will be described.
This embodiment provides support for improving the ability of a soccer through pass. Through-pass is performed when it is determined that the positions of the ally player and the enemy player in the pitch have a special relationship or will soon become such a special relationship. It is an exercise of “kicking” the ball.

  FIG. 1 is a diagram showing an example of the positional relationship of each player in the pitch. FIG. 1 shows an attacking player 10a serving as a through-pass, an attacking player 10b serving as a through-pass, and four defensive players 10c, 10d, 10e, and 10f blocking the through-pass (hereinafter referred to as “appropriately” Player 10 "), and the position of the goalkeeper 11. When each player 10 is in each position as shown in FIG. 1, the movement of kicking the ball 13 toward the reaching point that the receiver player 10 b running toward the end line 12 will reach several seconds later is a through-pass. is there. The through pass is considered to be a highly difficult play that is not successful unless many conditions such as the timing of kicking the ball 13, the direction of kicking, and the strength of kicking are met. The timing at which the ball 13 is kicked is preferably just before the player 10 b running toward the offside line 14 exceeds the offside line 14. If the kicking timing is a little later than that, it will be a violation of the rule called offside, and the pass will fail. On the other hand, if the kicking timing is too early than that time, the returning defensive player 10 catches up with the ball 13 first, and therefore fails. In order to allow the ball 13 to pass to the receiving player 10b at an advantageous position that satisfies the condition that it is closer to the goal and farther from the player 10 on the defensive side, it is most important to control the timing at which the ball 13 is kicked. is there. The exercise support apparatus according to the present embodiment supports control of the timing of kicking the ball 13 in this through path.

  FIG. 2 is a block diagram illustrating a hardware configuration of the exercise support apparatus according to the present embodiment. The exercise support apparatus includes a first transmitter / receiver 21, a second transmitter / receiver 22, a mounting unit 30-k (k = 1 to n), and a host device 40 that controls the entire system. Hereinafter, the mounting units 30-k (k = 1 to n) are collectively referred to as “mounting units 30” as appropriate. In FIG. 2, the mounting unit 30-1 is the player 10a of FIG. 1, the mounting unit 30-2 is the player 10b, the mounting unit 30-3 is the player 10c, the mounting unit 30-4 is the player 10d, and the mounting unit 30. −5 is attached to the player 10e, and the attachment unit 30-6 is attached to the player 10f. The remaining mounting units 30 are respectively mounted on the remaining players 10 in the pitch.

  The first transmitter / receiver 21 and the second transmitter / receiver 22 are installed one by one at each reference position outside the end line 12 shown in FIG. The first transmitter / receiver 21 and the second transmitter / receiver 22 perform transmission / reception of radio signals to / from each mounting unit 30 for measuring the distance between the reference position where each is installed and each mounting unit 30. Details will be described later.

  In FIG. 2, the mounting unit 30-k (k = 1 to n) includes an antenna 31, a radio circuit 32, a CPU (Central Processing Unit) 33, a memory 34, an audio circuit 35, and earphones 36L and 36R. Each part of the antenna 31, the radio circuit 32, the CPU 33, the memory 34, and the audio circuit 35 is built in the housing. The earphones 36L and 36R are respectively attached to the left and right ears of the player 10 wearing the attachment unit 30, and are connected to the audio circuit 35 via a cable drawn from the housing.

The radio circuit 32 of each mounting unit 30-k (k = 1 to n) plays two roles.
The first role is a role as a distance measuring sensor that measures the distance between itself and each of the first transmitter / receiver 21 and the second transmitter / receiver 22. Specifically, the distance measuring radio signal modulated by its own ID is transmitted to the first transmitter / receiver 21 and the second transmitter / receiver 22 every predetermined time (for example, 1/100 second). When each of the transceivers 21 and 22 receives a distance measuring radio signal modulated by a unique ID from each mounting unit 30, the ID of the mounting unit 30 obtained by demodulating the radio signal and its own installation position A response radio signal for distance measurement in which the carrier is modulated by a set of IDs unique to the ID is returned. The radio circuit 32 of each mounting unit 30 receives each ranging response radio signal modulated by its own ID and an ID unique to each of the installation positions of the transceivers 21 and 22 from the transceivers 21 and 22. Receive. Then, the distance x to the reference position of the transceiver 21 is calculated based on the time required for the wireless signal to reciprocate with the first transceiver 21, and the wireless signal between the second transceiver 22 is calculated. Based on the time required for the round trip, the distance y to the reference position of the transceiver 22 is calculated.

  As shown in FIG. 3, a circle 21c having a radius of a distance x measured by the first transmitter / receiver 21 and a reference position of the second transmitter / receiver 22 centered on a reference position of the first transmitter / receiver 21. And a circle 22c having a radius of the distance y measured by the second transceiver 22 can be drawn. In this case, the mounting unit 30 is at one of two points where the circumferences of the circles 21c and 22c intersect. Therefore, a set of distances x and y from the two transceivers 21 and 22 to a certain mounting unit 30 can be handled as data indicating the position of the mounting unit 30 in the horizontal plane. The radio circuit 32 transmits to the host device 40 a radio signal modulated by the position data x, y indicating the set of distances x, y and an ID unique to itself.

The second role is to receive a radio signal modulated by guide information, which will be described later, from the host device 40 and supply the guide information obtained by demodulating the radio signal to the CPU 33. In the present embodiment, the host device 40 transmits a radio signal modulated by the guidance information to the mounting unit 30-1 mounted by the player 10a who is the through path. This guidance information indicates the distance to the offside line 14 of the player 10b who is the recipient of the through pass when the player 10b does not exceed the offside line 14, and the offside line when the player 10b exceeds the offside line 14. It is information indicating only facts exceeding 14. Note that how to generate this guidance information will be described later.
The audio circuit 35 has a sound source 51. The sound source 51 generates a monaural 1-channel audio signal and supplies it to the earphones 36L and 36R. The earphones 36L and 36R provide the audio signal as sound to the left and right ears of the player 10.

  The CPU 33 of the mounting unit 30 controls the sound source 51 based on the guidance information received via the radio circuit 32, and sends a guidance sound indicating the approaching state to the offside line 14 of the player 10b through-pass receiver from the earphones 36L and 37R. Let it sound. More specifically, when the through-pass receiver 10b does not cross the offside line 14, and the guidance information received via the wireless circuit 32 indicates the distance to the through-pass player 10b offside line 14. The CPU 33 causes the sound source 51 to output an intermittent audio signal “beep-beep-beep”. Further, in this case, the time interval of the intermittent sound is shortened as the distance to the offside line 14 of the player 10b who receives the through-pass is shortened. On the other hand, when the guidance information received from the radio circuit 32 indicates that the player 10b of the through-pass has crossed the offside line 14, the CPU 33 causes the sound source 51 to output an audio signal of a continuous tone “Peep”. . Thus, by notifying the player 10 of an intermittent sound or a continuous sound with a variable time interval, it is possible to intuitively tell the player 10 the distance to the offside line 14 of the player 10b.

  The host device 40 includes a status management table memory 41, a control unit 44, a wireless circuit 46, and an antenna 47. The status management table memory 41 is a memory for storing a status management table.

  FIG. 4 is a diagram illustrating a data structure of the status management table. This table is a collection of a plurality of records corresponding to a plurality of players 10. Each record constituting this table has fields of “ID”, “role”, and “position”.

  In one record corresponding to one player 10, an ID unique to the mounting unit 30 attached to the player 10 is stored in the “ID” field. In this example, 101 is the mounting unit 30-1, 102 is the mounting unit 30-2, 103 is the mounting unit 30-3, 104 is the mounting unit 30-4, 105 is the mounting unit 30-5, 106 Are IDs corresponding to the mounting units 30-6. In the “role” field, “passer” indicating that the player 10 is the passer, “receiver” indicating that the player 10 is the passer, and “defense” indicating that the player 10 is the defender. ", One of the identifiers of" offense "(not shown in FIG. 4) indicating that the player 10 is an attacking player who is neither a passer nor a receiver is stored. The contents of these two fields of each record are set in advance through operation of an operator (not shown). In the “position” field, position data x and y indicating the position of the player 10 in the two-dimensional plane are stored.

  The control unit 44 includes a CPU, a RAM, a ROM, and the like, and is a device that controls the operation of the entire host device 40. A characteristic of the control performed by the control unit 44 is that the position data x, y in the “position” field of each record of the status management table is updated based on the radio signal received from each mounting unit 30. 1 control, and 2nd control which provides the guidance information produced | generated based on those position data x and y to the mounting unit 30 of the through pass originator 10a.

  In the first control, every time the control unit 44 receives a radio signal from each of the mounting units 30, the control unit 44 demodulates the radio signal to obtain ID and position data x, y. Then, the record having the ID stored in the “ID” field is specified from the status management table, and the “position” field of the record is updated with the acquired position data x, y.

  Further, in the second control, the control unit 44 obtains the position of each player 10 by referring to the “position” field of each record in the status management table periodically (for example, every 1/100 second). The guidance information is generated based on the position of each player 10. Then, the radio circuit 46 is instructed to transmit the guidance information to the mounting unit 30 mounted by the support target player who is the through pass. In accordance with this instruction, the radio circuit 46 transmits guidance information from the antenna 47 as a radio signal.

  In the present embodiment, among the components described above, the first transmitter / receiver 21, the second transmitter / receiver 22, the antenna 31 of the mounting unit 30, the radio circuit 32, the control unit 44 of the host device 40, the radio circuit 46, and the antenna. 47 serves as “state detection means for detecting the state of each of the plurality of players”. The CPU 33 of the mounting unit 30, the audio circuit 35, the earphones 36 L and 36 R, and the control unit 44 of the host device 40 Based on the states of the plurality of players detected by the state detecting means, a guide sound for causing the support target player that is at least a part of the plurality of players to perform an optimal exercise is generated and provided to the support target player. It plays the role of “guidance sound providing means”.

  Next, the operation of this embodiment will be described. In the present embodiment, the control unit 44 of the host device 40 repeats the through path support process, which is a process characteristic of the present embodiment, at predetermined intervals in parallel with the update of the “position” field of the status management table. FIG. 5 is a flowchart showing the contents of the through-pass support process. Desirably, the control unit 44 repeats this through-pass support process at a time density comparable to the update of the status management table.

In the through-pass support process, the control unit 44 first identifies the player 10 closest to the end line 12 among the defensive players 10c, 10d, 10e, and 10f (S100). The player 10 closest to the end line 12 is identified according to the following procedure. First, each record in which the identifier “defense” is stored in the “role” field in the status management table is specified.
Next, a distance h from the position indicated by the position data x, y in the “position” field of these records to the end line 12 is obtained. Specifically, the distance a between a reference position where the first transceiver 21 is located and a reference position where the second transceiver 22 is located, each of the first transceiver 21 and the second transceiver 22, and the mounting unit 30. By inputting the distances x and y between them into the following calculation formula (1), the distance h between the mounting unit 30 mounted on each player 10c, 10d, 10e, and 10f and the end line 12 is obtained. Then, the player 10 with the shortest distance h is identified as the player 10 closest to the end line 12.

Subsequently, the control unit 44 specifies a line parallel to the end line 12 and passing through the player 10 specified in step S100, that is, the offside line 14 (S110).
Further, the control unit 44 determines whether or not the player 10b who receives the through-pass is between the offside line 14 and the end line 12 specified in step S120 (S120). This determination is made according to the following procedure. First, a record in which the identifier of “receiver” is stored in the “role” field in the status management table, that is, the record of the player 10b who receives the through-pass is specified.

  Next, the length of the perpendicular drawn from the position indicated by the position data x, y in the “position” field of the record toward the end line 12, that is, the distance from the player 10b of the through-pass receiver to the end line 12, The distance from the offside line 14 to the end line 12 is compared. If the former distance is larger than the latter distance, the player 10b of the through pass does not cross the offside line 14, and if the former distance is smaller than the latter distance, the player 10b of the through pass recipient It is determined that the vehicle is over the offside line 14 and between the offside line 14 and the end line 12.

When it is determined in step S120 that the through-pass recipient player 10b is not between the off-side line 14 and the end line 12 (S120: No), the control unit 44 extends from the through-pass recipient player 10b position to the off-side line 14. Is calculated (S130).
Further, the control unit 44 transmits the guide information indicating the distance calculated in step S130 as a radio signal of the communication channel assigned to the mounting unit 30 of the player 10a who is the through pass (S140).

  When this wireless signal is received by the wireless circuit 32 of the mounting unit 30, the CPU 33 of the mounting unit 30 receives the guide information demodulated from the wireless signal from the wireless circuit 32. Then, the distance indicated by the guidance information is converted into an intermittent sound generation interval, and a parameter indicating the sound generation interval is supplied to the audio circuit 35. The interval between the intermittent sounds indicated by the parameters becomes shorter as the distance obtained from the guidance information is smaller. The sound source 51 of the audio circuit 35 that has received the parameter repeats the output of the audio signal having a relatively sharp attack with an interval indicated by the parameter. As a result, the earphones 36L and 36R output an intermittent sound of “pip-pip-pip-pip”, and the interval between the sound generation is the distance between the player 10b of the through-pass receiver and the offside line 14. Smaller is shorter.

When it is determined in step S120 that the through-pass recipient player 10b is between the offside line 14 and the end line 12 (S120: Yes), the control unit 44 determines that the through-pass recipient player 10b is in the offside position. The guide information shown is transmitted as a radio signal of the communication channel assigned to the mounting unit 30-1 of the player 10a who is the through-passer (S150).
When this wireless signal is received by the wireless circuit 32 of the mounting unit 30-1, the CPU 33 of the mounting unit 30-1 receives from the wireless circuit 32 guide information demodulated from the wireless signal. When the CPU 33 determines that the guidance information indicates that the player 10b of the through pass is in the offside position, the CPU 33 supplies a parameter for instructing output of a continuous sound to the audio circuit 35. The sound source 51 of the audio circuit 35 that has received the parameter continues to supply the audio signal to the earphones 36L and 36R. As a result, a continuous sound “Peep” is output from the earphones 36L and 36R.
When the predetermined time has elapsed (S160: Yes), the control unit 44 that has executed step S140 or step S150 returns to step S100 and repeats the subsequent processing.
Then, the series of processing shown in FIG. 5 ends when an end instruction is given from an operator (not shown).

  According to the present embodiment described above, intermittent sounds with sound generation intervals corresponding to the distance between the player 10b of the through pass and the offside line 14 are output from the earphones 36L and 36R of the both ears of the player 10a of the through pass. The Therefore, the player 10a of the through-pass sender senses the timing when the receiver player 10b crosses the offside line 14 depending on the sound generation interval of the intermittent sound output from the earphones 36L and 36R of his / her wearing unit 30-1. Training to issue a through-pass can be performed immediately before the timing. By repeating this training, a sense of issuing a through-pass can be cultivated. Specifically, it is possible to cultivate a sense unique to the through-pass that images (predicts) a change in the state of each player 10 for a while from the information obtained by glanced at the player 10b. . This feeling will be described in detail. Since the soccer game proceeds in a situation where the enemy player 10 constantly contends for the ball 13, the player 10 a who is the through pass is exposed to the risk of being deprived of the ball 13 as long as the ball 13 is held. The Since the player 10a of the passer of the through pass must lean most of the attention on the action against the take-off of the ball 13 by the enemy player 10 (for example, the action of putting his body between the enemy player 10 and the ball 13). Further, there is no room for continuing to visually observe the positioning of the player 10b of the receiver and the player 10 on the defensive side around the player 10b. An excellent player 10 grasps the positions of the player 10b and the surrounding defensive player 10 just by glancing at the direction of the player 10b of the receiver, and for a while, without directing his gaze in that direction, A change in the position of each player 10 is imaged (predicted). Then, a pass is made in accordance with the timing at which the player 10b of the receiver would have run to a position slightly ahead of the offside line 14. The ability to image (predict) the change in position of each player 10 is very sensory. Conventionally, the player can check the video of the movement of each player 10 later, or check whether each movement is good or bad. It was only possible to learn by repeating discussions between 10 people and instructing the leaders in a position overlooking the entire pitch by voice to tell when to make a through pass. On the other hand, according to the present embodiment, through the provision of the above-described guidance sound, the ability to image (predict) the change in the distance between the player 10b and the offside line 14 that is one element of the state of each player 10 is efficient. Can be enhanced.

(Second Embodiment)
The exercise support apparatus according to the first embodiment provides support for the support target player to acquire the exercise timing “through pass”. On the other hand, the exercise support apparatus according to the present embodiment provides support for causing the support target player to select the best option in a situation where there are a plurality of options regarding the exercise performed by the support target player. More specifically, in the present embodiment, the number of players 10 that can be through-pass recipients is increased from one to three. Then, the player 10 that has run from the player 10 toward the end line 12 and whose acceleration exceeds a threshold is selected as the best receiver, and the sound obtained by localizing the sound image at the position of the selected player 10 is Output from the earphones 36L and 36R of the player 10a.

FIG. 6 is a block diagram illustrating a hardware configuration of the exercise support apparatus according to the present embodiment. Similar to the first embodiment, this exercise support apparatus includes a first transmitter / receiver 21, a second transmitter / receiver 22, mounting units 30A-k (k = 1 to n), and a host device 40. Hereinafter, the mounting units 30A-k (k = 1 to n) are collectively referred to as “mounting units 30A” as appropriate. In the following description, the players 10a, 10b, 10c, 10d, 10e, and 10f shown in FIG. 1 are mounted units 30A-1, 30A-2, 30A-3, 30A-4, 30A-5, and 30A-6. Assume that two players 10 newly added as recipients of through-passes mount the mounting unit 30A-7 and the mounting unit 30A-8.
The mounting unit 30A includes the geomagnetic sensor 38 and the acceleration sensor 39, and includes filters 53L and 53R and amplifiers 54L and 54R between the sound source 51 of the audio circuit 35 and the earphones 36L and 36R, in the first embodiment. The configuration is different from that of the mounting unit 30.

The geomagnetic sensor 38 is affixed to the head of the player 10 wearing the mounting unit 30A, and outputs a signal indicating the orientation of the face (head) of the player 10. The acceleration sensor 39 outputs a signal indicating the acceleration of the player 10 wearing the mounting unit 30A.
In addition to the first role and the second role of the radio circuit 32 in the first embodiment, the radio circuit 32 samples the orientation of the face (head) detected by the geomagnetic sensor 38 at regular time intervals and obtains the orientation data. The third role to acquire and the fourth role to acquire acceleration data by sampling the acceleration detected by the acceleration sensor 39 at regular time intervals. Then, the radio circuit 32 uses the orientation data and acceleration data obtained by the third and fourth roles, and the position data x and y obtained by the first role described above for the radio of the communication channel assigned to itself. The signal is transmitted from the antenna 31 as a signal.
In this way, the orientation data, acceleration data, and position data x, y transmitted from each mounting unit 30A are received by the host device 40 and used as judgment materials for determining the player 10 who is the best recipient of the through path. The

  Filters 53L and 53R and amplifiers 54L and 54R provided in the audio circuit 35 are circuits for controlling the sound image localization of the guide sound to be heard by the player 10. Here, the filters 53L and 53R are head related impulse responses (HRIR) which are impulse responses of respective acoustic transmission paths from the target sound image position to the left and right ear canal entrances or the eardrum of the player 10 who is the listener. Is a filter that convolves the audio signal with the audio signal. The amplifiers 54L and 54R play a role of adjusting the volume of the guide sound for providing a sense of distance to the target sound image position. The head impulse response used by the filters 53L and 53R and the gains of the amplifiers 54L and 54R are individually switched according to the parameters supplied from the CPU 33.

  In the host device 40 according to the present embodiment, the data structure of the status management table in the status management table memory 41 is different from that of the first embodiment. FIG. 7 is a data structure diagram of the status management table in the present embodiment. In this table, each record associated with each player 10 has two fields of “direction” and “acceleration” in addition to the fields of “ID”, “role”, and “position”. As described at the beginning of this embodiment, in this embodiment, the number of players 10 who receive through-passes is increased from one to three. Therefore, there are also three records in which the identifier of “receiver” is stored in the “role” field. In the “ID” field, an ID unique to the mounting unit 30A mounted on each player 10 is stored. In this example, 101 is the mounting unit 30A-1, 102 is the mounting unit 30A-2, 103 is the mounting unit 30A-3, 104 is the mounting unit 30A-4, 105 is the mounting unit 30A-5, 106 Are IDs corresponding to the mounting units 30A-6, respectively. Reference numerals 107 and 108 denote IDs respectively corresponding to the mounting units 30A-7 and 30A-8 of the player 10 who has newly increased through-pass recipients.

  In the “orientation” field, orientation data indicating the orientation of the face of the player 10 is stored. In the “acceleration” field, acceleration data indicating the acceleration of the player 10 is stored. The storage contents of the “position”, “orientation”, and “acceleration” fields of each record are updated by the control unit 44. The procedure for updating the “position” field is the same as in the first embodiment. The procedure for updating the “orientation” and “acceleration” fields is as follows. That is, when a wireless signal from a certain mounting unit 30A is received by the wireless circuit 46, and the direction data indicating the face direction of the player 10 and the acceleration data indicating the acceleration are demodulated from the received signal, the control unit 44 A record corresponding to the player 10 wearing the mounting unit 30A as a transmission source is selected from the status management table, and the fields of “direction” and “acceleration” of the record are determined by demodulated direction data and acceleration data. Update.

  In the present embodiment, among the components shown in FIG. 6, the first transmitter / receiver 21, the second transmitter / receiver 22, the antenna 31 of the mounting unit 30 </ b> A, the radio circuit 32, the geomagnetic sensor 38, the acceleration sensor 39, and the host device 40. The control unit 44, the radio circuit 46, and the antenna 47 serve as “state detection means”, and the CPU 33, the audio circuit 35, the earphones 36L and 36R of the mounting unit 30A, and the control unit 44 of the host device 40 provide “guidance”. It plays a role as a sound providing means.

  Next, the operation of this embodiment will be described. In the present embodiment, the control unit 44 of the host device 40 performs a through-pass support process that is a characteristic process of the present embodiment in parallel with the update of the “position”, “orientation”, and “acceleration” fields of the status management table. Is repeated every predetermined time. FIG. 8 is a flowchart showing the processing contents of the through path support processing according to the present embodiment. In this embodiment, formation training is performed with the role of the recipient of the through pass shown in FIG.

  First, the control unit 44 specifies the player 10 closest to the end line 12 among the defensive players 10c, 10d, 10e, and 10f (S200), and then specifies the offside line 14 (S210). These steps S200 and S210 are performed according to the same procedure as steps S100 and S110 shown in FIG. Next, the control unit 44 determines whether or not at least one of the three players 10 through-pass recipients is on the other side of the offside line 14 as viewed from the end line 12 (S220). Specifically, the distance from the position indicated by the position data x, y in one of the “position” fields to the end line 12 among the three records in which the identifier “receiver” is stored in the “role” field It is determined whether the distance between the position of any player 10 and the end line 14 is greater than the distance from the offside line 14 to the end line 12. By this determination, a player who is not in the offside position (or a player who is in the offside position) can be specified.

  When it is determined in step S220 that there is at least one recipient player 10 beyond the offside line 14 as viewed from the end line 12 (S220: Yes), the control unit 44 determines whether the recipient 10 The process for selecting the player 10 that is the best option is executed. Specifically, the control unit 44 determines whether or not each player 10 that is on the other side of the offside line 14 as viewed from the end line 12 is facing the end line 12 (S230). This determination is made by referring to the “direction” field of the record corresponding to the corresponding player 10 in the status management table. When it is determined that there is a player 10 who is facing the end line 12 (S230: Yes), the control unit 44 determines whether or not the acceleration of the player 10 is larger than a preset threshold value (S230: Yes). S240). This determination is made by referring to the “acceleration” field of the record corresponding to the recipient player 10 in the status management table. When any of the player 10 receiving the pass starts to jump out behind the defender, the determination results in steps S230 and S240 are both “Yes”. There may be a case where a plurality of recipient players 10 in which both the determination results of steps S230 and S240 are “Yes” are generated. Various countermeasures in this case are conceivable. For example, the player 10 having the highest acceleration among the plurality of recipients 10 may be selected as the best option.

  When the recipient player 10 that is the best option is determined in step S240 (S240: Yes), the control unit 44 specifies the direction of the position of the player 10 as seen from the position of the player 10a that is the through pass. (S250). When step S250 ends, the control unit 44 executes a distance calculation process (S260). In this distance calculation process, two types of distances are calculated. One is the distance to the offside line 14 of the player 10 of the through pass determined in step S240, as in the first embodiment. The other is the distance from the player 10a who is the passer of the through path to the player 10 who is the receiver determined in step S240. Both of these distances are calculated by referring to the status management table. Then, the control unit 44 wirelessly communicates the communication channel in which the guidance information including information indicating the direction specified in step S250 and the two types of distances calculated in step S260 is assigned to the mounting unit 30A of the player 10a who is the through pass. It transmits as a signal (S270).

In step S220, when it is determined that there is no receiver player 10 beyond the offside line 14 (S220: No), in step S230, it is determined that the receiver player 10 is not facing the end line 12 (S230: No) When it is determined in step S240 that the acceleration is equal to or smaller than the threshold value (S240: No), or when step S270 is executed, the control unit 44 waits for a predetermined time. (S280: Yes), the process returns to step S200, and the subsequent processing is repeated.
Then, the series of processes shown in FIG. 8 ends when an end instruction is given from an operator (not shown).

  When the radio circuit 32 of the mounting unit 30A receives a radio signal from the host device 40 and demodulates the guide information from the received signal, the radio circuit 32 delivers the guide information to the CPU 33. The CPU 33 converts the amount of deviation between the direction of the player 10 indicated by the guidance information and the face direction detected by the geomagnetic sensor 38 into head impulse responses of the filters 53L and 53R, and the obtained heads. A parameter indicating the partial impulse response is supplied to the filters 53L and 53R, respectively. Further, the gain of each of the amplifiers 54L and 54R is increased or decreased according to the distance to the player 10 indicated by the guidance information. More specifically, the CPU 33 lowers the gain of the amplifiers 54L and 54R and lowers the volume of the guidance sound as the distance to the player 10 of the receiver increases. As a result, from the earphones 36L and 36R, a guide sound having a volume corresponding to the distance to the receiver player 10 is generated while the sound image is localized at the position of the receiver player 10. Further, as in the first embodiment, the CPU 33 controls the generation interval of the intermittent tone audio signal in the sound source 51 according to the distance to the offside line 14 of the player 10 indicated by the guidance information.

  In the present embodiment described above, sound obtained by localizing the sound image at the position of the player 10 that runs toward the end line 12 and whose acceleration exceeds a threshold value is output from the earphones 36L and 36R of the player 10a who is the through-pass player. The Therefore, the player 10a of the sender senses the position of the player 10 who is the best option on the basis of the sound images output from the earphones 36L and 36R of his / her wearing unit 30A-1, and passes the through path to that position. You can receive training. Then, by repeating this training, it is possible to develop a sense of sensing the ally player 10 who moves to the back of the defender. As described above, the excellent player 10 is good at the ability to image (predict) changes in the state of each player 10 for a while from the information obtained by glancing at the receiving player 10. If the ability is immature, even if the recipient player 10 moves out to the back of the defense, the player 10a cannot recognize the movement, so the pass cannot be made, and the jumping movement is useless. To become more. On the other hand, according to the present embodiment, the ability to image (predict) changes in the states of a plurality of allied players 10 at the same time can be efficiently increased, and the rate at which the movement to jump to the back is wasted is reduced. be able to.

(Third embodiment)
The exercise support apparatus according to the present embodiment supports the improvement of the ability to eliminate the gap between the volleyball receive formations.
FIG. 9 is a diagram showing the relationship of the defensive positions of each player 10 immediately before an attack is shot from the other side toward one side of the six-player volleyball court. 6 players 10k, 10j, 10m, 10n, 10p, 10q (hereinafter referred to as “player 10” as appropriate) and the position of the ball 13 attacked by the attacker 16 are prepared. The receive is an exercise in which the ball 13 shot into the own team is bounced upward with its own arm or the like. In FIG. 9, the balance between the distance from the player 10k to the player 10j and the distance from the player 10j to the player 10m is poor, and toward the region X separated from the rear players 10n, 10p, and 10q by substantially the same distance. When the ball 13 is shot from between the player 10k and the player 10j, neither player 10 can touch the ball 13 before landing, resulting in a goal loss. That is, the area X shown in FIG. 9 is not covered by any of the receiveable areas 17k, 17j, 17m, 17n, 17p, and 17q of the six players 10 (hereinafter referred to as “receivable area 17” as appropriate). It ’s a defensive formation. In order to increase the probability of success of receiving the attacked ball 13, it is necessary to secure the balance of the receivable area 17 of each player 10 and to adjust the defensive position according to the movement of the ball 13 in the enemy team. It is essential. The exercise support apparatus according to the present embodiment is a system that informs each player 10 of the location when a formation gap occurs and prompts each player 10 to adjust the position.

FIG. 10 is a block diagram illustrating a hardware configuration of the exercise support apparatus according to the present embodiment. In addition, in this figure, the same code | symbol is attached | subjected to the part which is common in each part of the exercise | movement assistance apparatus of the said 1st Embodiment (FIG. 2) and 2nd Embodiment (FIG. 6). The exercise support apparatus includes a first transmitter / receiver 21, a second transmitter / receiver 22, a third transmitter / receiver 23, a plurality of mounting units 30B-k (k = 1 to 6), a host device 40, and a ball position detection unit 50. . Hereinafter, the mounting units 30B-k (k = 1 to 6) are collectively referred to as “mounting units 30B” as appropriate.
10, the mounting unit 30B-1 is the player 10k of FIG. 9, the mounting unit 30B-2 is the player 10j, the mounting unit 30B-3 is the player 10m, the mounting unit 30B-4 is the player 10n, and the mounting unit 30B. −5 is attached to the player 10p, and the attachment unit 30B-6 is attached to the player 10q.

  The 1st transmitter / receiver 21 and the 2nd transmitter / receiver 22 are installed in each reference position of the other side of the net 15 seen from the end line outer side of the own team court, and the own team court. The third transceiver 23 is installed at a reference position near the center of the side line. Unlike the first embodiment and the second embodiment, the three transceivers 21 to 23 are used in this embodiment because a ball 50 whose position is changed in the height direction is included in the positioning target. This is because it is necessary to measure each distance from the three reference positions in order to specify 50 positions.

  The mounting unit 30B of this embodiment does not have the geomagnetic sensor 38 and the acceleration sensor 39 like those of the second embodiment. The audio circuit 35 is a circuit that generates an audio signal of a guide sound that informs the location of the gap area. In the audio circuit 35, the sound source 51 outputs an audio signal having a sound such as a sine wave (pure sound) that is easy to hear the effect of providing sound image localization, and that does not get tired even if it is heard for a long time. The functions and roles of the filters 53L and 53R and the amplifiers 54L and 54R are the same as those in the second embodiment.

  The ball position detection unit 50 is built in the ball 13. The ball position detection unit 50 transmits / receives a radio signal to / from the first transmitter / receiver 21, the second transmitter / receiver 22, and the third transmitter / receiver 23 every predetermined time (for example, 1/100 second). Based on the time required for transmission and reception, distances x, y and z between itself and each of the transceivers 21, 22, and 23 are calculated. Then, a radio signal in which the carrier is modulated by the position data x, y, z indicating the distance x, y, z is transmitted to the host device 40.

  The configuration of the host device 40 according to the present embodiment is the same as that of the second embodiment except for the data structure of the status management table. FIG. 11 is a data structure diagram of the status management table. This table is an aggregate of a plurality of records each corresponding to the player 10 wearing the mounting unit 30B. Each record forming this table has fields of “ID”, “exercise ability”, and “position”.

  In the “ID” field, an ID unique to the mounting unit 30B mounted on each player 10 is stored. In this example, 201 is a mounting unit 30B-1, 202 is a mounting unit 30B-2, 203 is a mounting unit 30B-3, 204 is a mounting unit 30B-4, 205 is a mounting unit 30B-5, 206 Are IDs corresponding to the mounting units 30B-6, respectively. In the “exercise ability” field, exercise ability parameters are stored. The athletic ability parameter is a parameter indicating the height of each athletic ability, such as a physique characteristic such as height and weight of each player 10, jumping power, dynamic visual acuity, and the like. The contents of these two fields of each record are set in advance through operation of an operator (not shown). In the “position” field, position data x and y indicating the position of the player 10 in the horizontal plane is stored. As in the first embodiment, the control unit 44 updates the position data x, y in the “position” field of each record of the status management table based on the radio signal received from each mounting unit 30B. Further, the control unit 44 demodulates the radio signal received from the ball position detection unit 50 and acquires position data x, y, z indicating the position of the ball 13 in the three-dimensional space.

  In the present embodiment, among the components shown in FIG. 10, the first transmitter / receiver 21, the second transmitter / receiver 22, the antenna 31 of the mounting unit 30B, the wireless circuit 32, the control unit 44 of the host device 40, the wireless circuit 46, The antenna 47 serves as “state detection means”, and the CPU 33 of the mounting unit 30B, the audio circuit 35, the earphones 36L and 36R, and the control unit 44 of the host device 40 serve as “guidance sound providing means”. Fulfill.

  Next, the operation of this embodiment will be described. In the present embodiment, the control unit 44 of the host device 40 performs receive support processing at predetermined intervals in parallel with updating the “position” field of the status management table and specifying the position of the ball 13 in the three-dimensional space. Run repeatedly. FIG. 12 is a flowchart showing the processing contents of this receive support processing.

  First, the control unit 44 executes a guidance sound occurrence determination process (S300). This guidance sound generation possibility determination process is a process for determining whether to perform the process for determining the gap area and generating the guidance sound for notifying the location, specifically, the process from steps S310 to S350. is there. Various types of processing can be considered. In the first aspect, in the guidance sound generation possibility determination process, the current position of the ball 13 is based on position data x, y, z obtained by demodulating a radio signal periodically received from the ball position detection unit 50. Is in the opponent's side, and if it is in the opponent's side, it is determined that the processing from step S310 to step S350 should be executed. In the second aspect, when the change in the position of the ball 13 is monitored based on the position data x, y, z, and it is recognized that the toss has risen in the opponent team, the processing from step S310 to S350 should be executed. to decide. Specifically, it is determined that the toss has increased when the position of the ball 13 is within the opponent's team and the height of the ball 13 exceeds the upper end of the net and reaches a maximum value. In the third aspect, in the guidance sound occurrence determination process, when it is recognized that a serve or an attack has been performed from the enemy court, it is determined that the processes from step S310 to step S350 should be executed. Specifically, when the current position of the ball 13 specified by the position data x, y, z exceeds the net and enters the teammate, it is determined that the enemy court has served or attacked. In a preferred mode, the control unit 44 selects any one of the first to third modes in accordance with an operation of an operator (not shown), and executes a guidance sound occurrence determination process in the selected mode.

  In step 300, the control unit 44 that has determined that the processing from step S310 to step S350 should be executed (S300: Yes), first, the ball 13 specified by the contents of the status management table and the position data x, y, z. Based on the position, the receivable area 17 of each player 10 is specified (S310). The receivable area 17 is an area where the ball 13 that has been shot into the player's own team can touch the landing before landing, and the control unit 44 can receive this for each of the players 10k, 10j, 10m, 10n, 10p, and 10q. The area 17 is obtained individually. The size and shape of the receivable area 17 are determined depending on the exercise ability and position of the player 10 and the position of the ball 13. Therefore, one record corresponding to each player 10 is identified from the status management table, and the data stored in the “exercise ability” and “position” fields of the identified record and the data indicating the position of the ball 13 are By repeating the process of inputting to the receiveable area analysis function using the value of as a variable, the receiveable areas 17 of all the players 10 in the player's own team are specified.

The control unit 44 obtains an area having a certain spread around the position of each player 10 as the receiveable area 17. In that case, the control part 44 determines the shape and magnitude | size of the receivable area | region 17 according to the following rules, for example.
a. Depending on where on the opponent's court the attack is performed, the player 10 that is easy to react to the ball 13 and the player 10 that is not so are different. The player 10 having a long distance from the ball 13 at the time of attack has a long time until the ball 13 arrives and can easily react to the ball 13. The player 10 having a short distance from the ball 13 at the time of attack has a short time until the ball 13 arrives, and it is difficult to react to the ball 13. Therefore, the closer to the current position of the ball 13, the smaller the receivable area 17, and the wider the player farther from the current position of the ball 13, the wider the receivable area 17.
b. For example, when serving from an enemy court, the ball 13 flies from the opponent court through the sky into the teammate court. Therefore, the area where the rear guard can be received 17 is made wider than the area where the front guard can receive.
c. According to the rule b, the player 10 blocking with the vanguard has a reduced area of the receivable area 17, but if the block is successful, the ball 13 does not fall into the area behind the player 10. Therefore, with respect to the player 10 blocking with the vanguard, the shape of the receiveable area 17 is adjusted so as to extend slenderly behind the player 10 on the assumption that the block is successful.
d. When designated by operation of an operator (not shown), the athletic ability of each player 10 designated by the status management table is referred to, and the player 10 with high athletic ability expands the receiveable area 17 as a whole, and the athletic ability The player 10 having a low value shrinks the receivable area 17 as a whole.
e. When the trajectory of the ball 13 from the opponent's court to the player 10 is projected on the own court, a long “shadow” region is projected geometrically backward. Accordingly, the receivable area 17 behind the player 10 is made longer than the front receivable area 17.

The control unit 44 that has specified each of the receivable areas 17 of all the players 10 within the player's team specifies a gap area (S320). The gap area is an area within the player's side and does not overlap with any of the receivable areas 17 of any player 10.
The control unit 44 that has specified the gap area specifies each of the players 10 within the player's team as the support target player, and specifies the relative direction of the gap area with respect to the front direction of each face for each support target player ( S330). More specifically, in this process, assuming that the support target player faces the ball 13, the straight line connecting the projected position of the ball 13 on the horizontal plane and the position of the support target player indicated by the status management table Then, an angle formed by a representative point of the gap area (for example, the gravity center position of the gap area) and a straight line connecting the position of the support target player is obtained. This angle is used as information indicating the relative direction of the gap area viewed from the support target player. Next, the control unit 44 specifies the distance between the position of each support target player and the representative point of the gap area (S340). Then, the control unit 44 creates guidance information indicating the direction specified in step S330 and the distance specified in step S340 for each support target player, and sets the carrier of the communication channel assigned to the mounting unit 30 of the support target player. Modulated by the guide information and transmitted as a radio signal (S350).

In step S300, when it is determined that the processes from step S310 to S350 should not be executed (S300: No), or when step S350 is executed, the control unit 44 waits for a predetermined time ( (S360: Yes), the process returns to step S300, and the subsequent processing is repeated.
When the radio circuit 32 of the mounting unit 30B receives a radio signal from the host device 40 and demodulates the guide information from the received signal, the radio circuit 32 delivers the guide information to the CPU 33. When this guidance information is delivered, the CPU 33 of the mounting unit 30B sets a head impulse response that localizes the sound image in the direction of the gap area indicated by the guidance information in the filters 53L and 53R. Further, the CPU 33 converts the distance to the gap area indicated by the guide information into the gains of the amplifiers 54L and 54R, and sets the obtained gains in the amplifiers 54L and 54R. As a result, from the earphones 36L and 36R, a guide sound in which the sound image is localized in the gap area is generated.
The series of processing shown in FIG. 12 ends when an end instruction is given from an operator (not shown).

  As described above, in this embodiment, the sound obtained by localizing the sound image in the gap region of the receive formation is output from the earphones 36L and 36R of each ear of the player 10 taking the formation. Conventionally, a leader who is in a position overlooking the entire court informs each player 10 on the court of a gap area and correction of positioning to eliminate the area by voice or while play is interrupted. In addition, the ability to eliminate the gap in the receiving formation could only be increased by repeated training in which each player 10 discussed the quality of each positioning. On the other hand, in the present embodiment, each player 10 taking the receiving formation senses the formation gap using the sound images of the sounds output from the earphones 36L and 36R of each mounting unit 30B as a clue, and fills the gap. Can be trained to adjust each position. Therefore, it is possible to enhance the ability to maintain a free formation without performing voice guidance by a leader or discussion between players 10 as conventionally performed, and without interrupting play.

(Fourth embodiment)
In this embodiment, a driver and a passenger of a motorcycle with a side car for racing called a kneeler are used as support target players, and the two support target players support improvement in turning (cornering) ability.
FIG. 13 is a diagram showing a motorcycle with a side vehicle that turns to the side (left side) to which the side vehicle is connected, and the postures of the driver 18 and the passenger 19 during the turn. During the turning of the motorcycle with a side car, strong centrifugal force is generated in the direction opposite to the turning direction. Therefore, the center of gravity of both the driver 18 and the passenger 19 is moved in the turning direction to resist the centrifugal force. Maintaining high-speed driving while preventing falling motorcycles. As shown in FIG. 13, the passenger 19 moves the center of gravity of the driver 18 by performing an extreme center of gravity movement so as to get out of the side vehicle without performing a steering wheel operation for manipulating the motorcycle itself. It plays a role in compensating for the shortage of quantity. In the present embodiment, when the motorcycle with a side vehicle is turned, the driver 18 handles (handle rotation and center of gravity movement) and the passenger 19 center of gravity moves in harmony.

  FIG. 14 is a block diagram illustrating a hardware configuration of the exercise support apparatus according to the present embodiment. The exercise support apparatus includes a handling detection sensor 61, a gravity center movement detection sensor 81, an ADC 64, a CPU 65, a memory 66, earphones 67L and 67R, earphones 87L and 87R, and an audio circuit 68. Of each part shown in FIG. 14, the handling detection sensor 61 is mounted on the handle of a motorcycle with a side vehicle, and the center-of-gravity movement detection sensor 81 is mounted on the floor of the seat of the side vehicle. The earphones 67L and 67R are respectively attached to the left and right ears of the driver 18, and the earphones 87L and 87R are respectively attached to the left and right ears of the passenger 19. The remaining portions are built into the housing, and the housing is attached to the driver 18 via a mounting member (not shown).

  The handling detection sensor 61 is a sensor for detecting the amount of rotation of the handle (that is, angular velocity [radians / second]) and its direction. The handling detection sensor 61 detects the amount and direction of rotation of the steering wheel with respect to the position of the steering wheel (hereinafter referred to as “neutral position”) when the motorcycle with a side vehicle goes straight, and the detected amount and direction of rotation. Is output to the ADC 64. When the amount of rotation of the handle to the left increases, the amplitude of the analog signal output from the handling detection sensor 61 increases to the positive side by the amount of rotation, and when the amount of rotation of the handle to the right increases, the handling detection sensor The amplitude of the analog signal output by 61 increases toward the negative side by the amount of rotation.

The center-of-gravity movement detection sensor 81 has a pair of left and right force plates on which the passenger 19 puts left and right feet, detects the pressure applied to these force plates, and moves the center of gravity of the passenger 19 (that is, the angular velocity [radians / radians / Second]) and its direction. The center-of-gravity movement detection sensor 81 detects a center-of-gravity movement amount and its direction based on the center of gravity (hereinafter referred to as “neutral center-of-gravity”) when the motorcycle with a side vehicle goes straight, and the detected movement amount and its direction are detected. The analog signal shown is output to the ADC 64. When the amount of movement of the center of gravity to the left increases, the amplitude of the analog signal output from the center of gravity detection sensor 81 increases to the positive side by the amount of movement, and when the amount of movement of the center of gravity increases to the right, The amplitude of the analog signal output from the detection sensor 81 increases toward the negative side by the amount of movement.
The ADC 64 converts the analog signals respectively supplied from the handling detection sensor 61 and the gravity center movement detection sensor 81 into digital signals and supplies them to the CPU 65.

Is generated. The fundamental frequency of the sound generated by both sound sources 71 and 72 may be set to any setting as long as a chordal relationship is established between them.
The audio signal generated by the first sound source 71 is supplied to the first basic frequency adjuster 73, and the audio signal generated by the second sound source 72 is supplied to the second basic frequency adjuster 74. Each of the fundamental frequency adjusters 73 and 74 performs signal processing for shifting the fundamental frequency on the audio signal supplied from the sound sources 71 and 72. The extent to which the fundamental frequency is shifted in either the high frequency side or the low frequency side depends on the basic frequency adjustment parameters supplied from the CPU 65 to the basic frequency adjusters 73 and 74.

The audio signal of the first sound that has undergone the signal processing by the first fundamental frequency adjuster 73 is supplied to the first multiplier 77L and the second multiplier 77R, respectively. The audio signal of the second sound that has undergone the signal processing by the second fundamental frequency adjuster 74 is supplied to the third multiplier 78L and the fourth multiplier 78R, respectively.
The multipliers 77L and 77R are means for generating left and right two-channel audio signals from the first sound audio signal output from the first sound source 71 and adjusting the volume balance of the left and right two-channel audio signals. . Similarly, the multipliers 78L and 78R generate right and left two-channel audio signals from the second sound audio signal output from the second sound source 72, and adjust the volume balance of the left and right two-channel audio signals. It is. The CPU 65 outputs a first panning coefficient parameter that specifies the left and right volume balance of the first sound and a second panning coefficient parameter that specifies the left and right volume balance of the second sound. Each of these panning coefficient parameters is a numerical value within the range of 0 to 1.0.

  The subtracter 56 outputs a numerical value obtained by subtracting the first panning coefficient parameter from 1. The subtractor 57 outputs a numerical value obtained by subtracting the second panning coefficient parameter from 1. The multiplier 77L multiplies the first panning coefficient parameter by the audio signal of the first sound, and outputs the result as an L-channel audio signal of the first sound. The multiplier 77R multiplies the numerical value output from the subtractor 56 by the audio signal of the first sound, and outputs the result as an R-channel audio signal of the first sound. On the other hand, the multiplier 78L multiplies the second panning coefficient parameter by the audio signal of the second sound, and outputs the result as an L-channel audio signal of the second sound. The multiplier 78R multiplies the numerical value output from the subtractor 57 by the audio signal of the second sound, and outputs the result as an R-channel audio signal of the second sound. The mixer 79 mixes the L-channel audio signals of the first and second sounds output from the multipliers 77L and 78L, and outputs the L-channel audio signal as a mixing result to the L-channel earphones 67L and 87L. To do. The mixer 80 mixes the R-channel audio signals of the first and second sounds output from the multipliers 77R and 78R, and outputs the R-channel audio signal as a mixing result to the R-channel earphones 67R and 87R. To do.

  In the present embodiment, among the components shown in FIG. 14, the handling detection sensor 61, the center-of-gravity movement detection sensor 81, and the ADC 64 serve as “state detection means”, and the CPU 65, the audio circuit 68, and the earphone 67L, 67R, 87L, and 87R serve as “guidance sound providing means”.

  Next, the operation of this embodiment will be described. FIG. 15 is a diagram illustrating parameters supplied from the CPU 65 and the contents of signal processing performed by each unit of the audio circuit 68 in accordance with the parameters.

  When the handling detection sensor 61 detects the rotation of the handle from the neutral position in the right direction or the left direction, the CPU 65 sets the first basic frequency adjustment parameter that specifies the shift amount of the basic frequency according to the rotation amount as the first basic frequency adjustment parameter. While supplying to the frequency adjuster 73, the 1st panning coefficient parameter according to the direction of the rotation is output. Specifically, the CPU 65 generates a first fundamental frequency adjustment parameter for shifting the fundamental frequency of the first sound to the high frequency side when the direction of rotation of the handle is left, and sets the shift amount to the rotation amount. On the other hand, when the direction of rotation of the handle is right, a first fundamental frequency adjustment parameter for shifting the fundamental frequency of the first sound to the low frequency side is generated, and the shift amount is proportional to the rotation amount. . When the direction of rotation of the handle is left, a first panning coefficient parameter indicating a predetermined coefficient larger than 0.5 (for example, 0.75) is supplied, and the direction of rotation of the handle is right. In some cases, a first panning coefficient parameter is provided that indicates a predetermined coefficient (eg, 0.25) that is less than 0.5.

  The first fundamental frequency adjuster 73, which has been supplied with the first fundamental frequency adjustment parameter described above, switches the shift amount and direction of the fundamental frequency of the audio signal of the first sound passing through itself according to the parameter. . In addition, the first multiplier 77L and the second multiplier 77R that have received the first panning coefficient parameter described above use, as its parameter, the distribution ratio of the volume level of the audio signal that has been frequency-shifted through the first multiplier 77L and the second multiplier 77R. Switch accordingly. As a result, the pitch and the direction of the sound image of the first sound generated through the mixing by the first mixer 79 and the second mixer 80 change according to the operation of the driver 18 handle.

  In addition, when the CPU 65 detects the movement of the center of gravity from the neutral center of gravity to the right or left by the center of gravity detection sensor 81, the CPU 65 sets a second fundamental frequency adjustment parameter for designating a shift amount of the fundamental frequency according to the amount of movement. While supplying to the 2nd fundamental frequency regulator 74, the 2nd panning coefficient parameter according to the direction of the movement is output. Specifically, the CPU 65 generates a second fundamental frequency adjustment parameter for shifting the fundamental frequency of the second sound to the high frequency side when the direction of movement of the center of gravity is the left, and sets the shift amount to the amount of movement. On the other hand, when the direction of movement of the center of gravity is right, a second fundamental frequency adjustment parameter for shifting the fundamental frequency of the second sound to the low frequency side is generated, and the shift amount is proportional to the movement amount. . In addition, when the direction of movement of the center of gravity is left, a second panning coefficient parameter indicating a predetermined coefficient (for example, 0.75) greater than 0.5 is supplied, and the direction of movement of the center of gravity is right. In some cases, a second panning coefficient parameter indicating a predetermined coefficient smaller than 0.5 (eg, 0.25) is supplied.

The second fundamental frequency adjuster 74 that has received the second fundamental frequency adjustment parameter switches the shift amount and direction of the fundamental frequency of the audio signal of the second sound that passes through the second fundamental frequency adjuster 74 according to the parameter. . In addition, the third multiplier 78L and the fourth multiplier 78R that have received the second panning coefficient parameter described above use, as their parameters, the distribution ratio of the volume level of the frequency-shifted audio signal that passes through the third multiplier 78L and the fourth multiplier 78R. Switch accordingly. As a result, the pitch and the direction of the sound image of the second sound generated through the mixing by the first mixer 79 and the second mixer 80 change according to the movement of the weight of the passenger 19.
Here, when the fundamental frequency adjustment parameter having the same value is supplied to the first fundamental frequency adjuster 73 and the second fundamental frequency adjuster 74, the CPU 65 has the frequencies of the audio signals of the first sound and the second sound. Of the fundamental frequency adjustment parameter and the shift amount in the first fundamental frequency adjuster 73 and the second fundamental frequency adjuster 74 so that is shifted while maintaining the original frequency ratio (that is, the frequency ratio in the chord relationship). Integrate and control relationships.

The above description is summarized in the table as follows.

As described above, in this embodiment, when the driver 18 rotates the handle leftward (rightward), the fundamental frequency of the first sound is increased by the amount corresponding to the amount of rotation of the handle. When shifting to the (low frequency side) and the passenger 19 moves the center of gravity in the left direction (right direction), the fundamental frequency of the second sound is increased to the high frequency side (low frequency range) according to the amount of movement. To the side). Here, when the rotation direction of the handle and the movement direction of the center of gravity of the passenger 19 coincide with each other and the movement amount of the center of gravity of the passenger 19 is appropriate with respect to the rotation amount of the handle 19, the first and second Each fundamental frequency of the sound shifts while maintaining the same frequency ratio in the same direction. Therefore, the first and second sounds that can be heard by the driver 18 and the passenger 19 constitute a chord. However, if the rotation direction of the handle and the movement direction of the center of gravity of the passenger 19 do not match, or even if the directions match, the movement amount of the center of gravity of the passenger 19 is unbalanced with respect to the rotation amount of the handle. In some cases, the frequency ratio of the fundamental frequencies of the first and second sounds changes from the originally desired frequency ratio, resulting in an inharmonic state. Therefore, the driver 18 and the passenger 19 can determine whether or not the movements of the first and second sounds audible from the earphone are in harmony with each other.
In the present embodiment, if the direction of rotation of the handle by the driver 18 and the direction of movement of the weight by the passenger 19 are the same, the sound images of the first sound and the second sound are panned in the same direction. It has become. Therefore, by paying attention to the direction of the sound image of the first sound and the second sound during turning, the driver 18 matches the direction of rotation of his / her handle and the direction of weight movement of the passenger 19. The passenger 19 can also confirm that the direction of movement of the center of gravity of the passenger 19 coincides with the direction of rotation of the handle by the driver 18.

(Other embodiments)
The present invention can be modified in various ways.

(1) In the first and second embodiments described above, two transceivers 21 and 22 are provided around the pitch, and when each mounting unit 30 transmits a distance measurement radio signal, and when the transceivers 21 and 22 are transmitted. The distance between each mounting unit 30 and the transceivers 21 and 22 was obtained by multiplying the time required for receiving the ranging response wireless signal from the reception time by the propagation speed of the wireless signal in the air. On the other hand, three or more transmitters / receivers may be installed around the pitch at predetermined intervals, and ranging response wireless signals may be transmitted from the respective transmitters / receivers. According to this modification, for example, the position of the player 10 within the pitch can be reliably identified even when the transmitter / receiver cannot transmit a radio signal having a strong radio wave intensity that covers the entire pitch.
(2) In each of the first to third embodiments, a ranging radio signal transmitted from the transceiver to the mounting unit 30 instead of transmitting the ranging radio signal first from the mounting unit 30 side. The mounting unit 30 returns the ranging response wireless signal, and the transmitter / receiver determines the distance from the mounting unit 30 based on the required time between the transmission of the ranging wireless signal and the reception of the ranging response wireless signal. It may be specified.
(3) In each of the first to third embodiments, a radio signal in which a carrier is modulated by a time code of a transmission time is transmitted from a transmission device provided at each of a plurality of reference positions around the pitch, and the wireless signal is received. The mounted unit 30 obtains the distance from each transmitting device based on the time indicated by the time code obtained by demodulating the received radio signal and the difference at the time of reception, and its own position determined based on the obtained distance May be transmitted. In this case, when the distance between each transmitting device and the mounting unit 30 is 0, the time settings of the timers of the transmitting device and the mounting unit 30 are calibrated so that the difference between the transmission time and the receiving time of the wireless signal is 0. In addition, the distance should be measured. According to this modification, the position of the mounting unit 30 can be specified only by transmitting a wireless signal from one of the reference position and the mounting unit 30 to the other, and the wireless signal can be reciprocated as in the first and second embodiments. There is no need to let them.

(4) In the first embodiment and the second embodiment, a guide sound that prompts the sensing of the distance between the player 10 and the offside line 14 that jumps out to the back of the defender and the position of the player 10 is transmitted. The sound is generated from the mounting unit 30 of the player 10a. On the other hand, the mounting unit 30 of the defensive player 10 blocking the through-pass may sound a guide sound for adjusting the defensive formation. This modification can be realized by the following configuration, for example. First, the positions of three or four players 10 who form a defense line are specified. Then, when the player 10 closest to the end line 12 among the three or four of them is the side player 10, a loud warning sound is generated from the mounting unit 30 of the player 10. In soccer, it is convenient to use an offside trap tactic that one or two of the three or four defenders in a line are positioned slightly behind the side defender. It is said that it is good. Therefore, when the player 10 on the right side or the left side generates a loud warning sound from his / her wearing unit 30, he / she senses that his / her position is too close to the goal line 12, and The positioning can be corrected in accordance with 10.
An overview of the above-described modified exercise support apparatus is as follows. “State detection means for detecting the state of each of the plurality of players, and an optimal exercise for the support target player that is at least a part of the plurality of players based on the states of the plurality of players detected by the state detection means. A guidance sound providing means for generating a guidance sound to be provided to the support target player, wherein the state detection means is a position of a plurality of players forming an offside line of soccer as a state of the plurality of players. And the guidance sound providing means uses the side player among the plurality of players forming the offside line as a support target player, and sets the end line based on the positions of the plurality of players detected by the state detecting means. When the closest player is found and it is determined that the closest player and the player to be supported are the same player, Exercise support apparatus "which is characterized by changing the sound mode of guiding sound provided in supporting target player.

(5) In the second embodiment, the sound image localization is controlled by convolving the head impulse response with the filters 53L and 53R into the audio signal generated by the sound source 51. However, a delay circuit may be mounted instead of the filters 53L and 53R, and the sound image localization may be controlled by adjusting the delay amount of the delay circuit and the gains of the amplifiers 54L and 54R at the subsequent stages.
(6) In the second and third embodiments, the guide sound output from the earphones 36L and 36R may be panned in the direction of the player 10 of the through-pass recipient or the direction of the defensive gap area. This modification can be realized by mounting a pair of multipliers that change the distribution ratio of the sound volume of the left and right two channels instead of the filters 53L and 53R and the amplifiers 54L and 54R. In the case of this modification, although it is difficult to grasp the distance to the player 10 of the through-pass recipient and the gap area of the defensive formation using the guide sound as a clue, it is possible to grasp the direction thereof.
(7) In the first embodiment and the second embodiment described above, sounds having sound generation intervals corresponding to the distance between the through-pass recipient player 10b and the offside line 14 are attached to the left and right ears of the through-pass player 10a. The earphones 36L and 36R that were used were pronounced. On the other hand, the sound generation interval of the sound generated from the speakers provided around the pitch may be changed according to the distance. Thereby, all the players 10 including the player 10a who is the through-passer can sense the distance between the player 10b and the offside line 14. Further, the first mode in which sound is generated from the earphones 36L and 36R of the player 10a of the through-pass player and the second mode in which sound is generated from the speaker may be selected. When the second embodiment is configured by this modification, the sound image localization of the sound generated from the speaker may be controlled by adjusting the delay amount and gain of the audio signal supplied from the sound source 51 to the speaker.

(8) In the first embodiment, until the through-pass recipient player 10b reaches the offside line 14, an intermittent sound is generated from the mounting unit 30 of the outgoing player 10a, and at the moment the off-side line 14 is exceeded. The intermittent sound was switched to a continuous sound. On the other hand, the sound may be silenced at the moment when the offside line 14 is exceeded.
(9) In the second embodiment, the player 10 whose face is facing the end line direction is set as one condition for becoming a recipient of the through pass. However, instead of this condition, the player 10 moving in the end line direction may be a condition for becoming a recipient of the through pass. Alternatively, the condition that the face is facing the end line and the player 10 is moving in the end line direction may be a condition for receiving the through-pass.

(10) In each of the first to fourth embodiments, each state of the position, orientation, acceleration, handling amount of the driver 18 and its direction, the amount of movement of the center of gravity of the passenger 19 and its direction, etc. Detection was performed using the radio circuit 32, the geomagnetic sensor 38, the acceleration sensor 39, the handling detection sensor 61, the gravity center movement detection sensor 81, and the like, and the sounding mode of the guidance sound was controlled according to the state. However, the state that determines the sound generation mode of the guidance sound is not limited to that of the first to fourth embodiments, and may be either a static state or a dynamic state that is visible from the outside. Here, the static state is a state that can be quantified as the position and orientation of representative points of the body such as the waist, torso, hand, foot, and head of the player 10. The dynamic state includes acceleration, velocity, angular velocity (rotational moment), inclination, distortion (for example, muscle expansion / contraction), pressure (for example, compression such as kicking of the foot or grip of the palm), It is a state that can be quantified as (tensile). The scale of state quantification may be uniaxial, biaxial or triaxial. If the scale is 1 axis, the state of the player 10 is quantified as a scalar quantity, and if it is 2 axes or 3 axes, the state is quantified as a vector quantity.
Also, the means for detecting these states is not limited to those in the first to fourth embodiments. A biaxial acceleration sensor that detects acceleration in the biaxial direction (x, y) on a plane parallel to the ground, a triaxial acceleration sensor that also detects acceleration in the height direction (z), and a velocity detection. A speed sensor, an angular velocity sensor that detects angular velocity (rotational moment), an inclination sensor, a pressure sensor, and the like may be mounted instead of the geomagnetic sensor 38, the acceleration sensor 39, the handling detection sensor 61, and the gravity center movement detection sensor 81. Further, the position of the player 10 may be calculated using GPS (global positioning system) positioning information.
Further, when the acceleration sensor 39 of each mounting unit 30 is replaced with a multi-axis acceleration sensor, the direction of the acceleration is obtained in addition to the magnitude of the acceleration, the movement is in the end line direction, and the acceleration direction is the end line. The direction may be one condition for becoming a recipient of the through path. The moving direction of each player 10 can be obtained based on a time-series change in the position of each player 10 detected periodically.

(11) In the third embodiment, in addition to the position of each player 10, athletic ability, and the position of the ball 13, the player's own face (head) direction, line of sight, and posture (receivable area as the posture leans forward) The sensor determines other variables that correlate with the shape and size of the receivable area, such as the position of the center of gravity and the position of the center of gravity (the lower the center of gravity is, the wider the receivable area is). It may be. Specifically, the mounting unit 30B of the third embodiment has a geomagnetic sensor 38 and an acceleration sensor 39, as in the second embodiment, and uses the detection values of these sensors to determine the receivable region. You may calculate in more detail.
(12) In the fourth embodiment, the volume balance between the first sound and the second sound may be changed according to the ratio of the handling amount of the driver 18 of the motorcycle with a side vehicle and the center of gravity movement amount of the passenger 19. Good. This modification can be realized by the following configuration, for example. First, audio signals of the same volume with different timbres are generated from the first sound source 71 and the second sound source 72, the audio signals are amplified by each of the two amplifiers, mixed by the mixer, and the earphones 67L, 67R, Output from 87L and 87R. Then, the gain of one amplifier is changed according to the handling amount of the driver 18, and the gain of the other amplifier is changed according to the amount of movement of the center of gravity of the passenger 19. According to this modification, every time the handling amount of the driver 18 and the center-of-gravity movement amount of the passenger 19 are changed by turning, the volume of the sound heard by both changes. Furthermore, if the amount of handling and the amount of movement of the center of gravity do not match, only the volume of one of the two sounds will be noticeably loud, so the driver 18 and passenger 19 have a poor balance between the amount of handling and the amount of weight movement. I can confirm that.

(13) In each of the first to fourth embodiments, the present invention is applied to training of soccer, volleyball, and side motorcycle. However, the present invention may be applied to training for other sports. For example, the situation determination ability necessary for tennis and table tennis performed by a one-to-one player can be cultivated through training performed by attaching the mounting unit 30 to each of the players 10. Also, baseball, rugby, and American football are played by two teams that stand against each other, including stealing and bunt processing, which is a baseball game involving a single standing player and a plurality of defensive players. The ability to judge the situation required for yacht races, gymnastics, cutter boats, circus, etc., performed by a plurality of players working together, is also provided through training performed by attaching the mounting unit 30 to each of those players 10 Can be nourished.
(14) In the first embodiment, the length of the intermittent sound generation interval is controlled according to the distance between the player 10 f of the through-pass receiver and the offside line 14. However, the length of the silence interval may be controlled according to the distance between the two. In short, it is only necessary to control the number of times of sound generation per unit time in accordance with the distance between the player 10 of the through-pass and the offside line 14. Alternatively, the distance between the two may be converted into a pitch (frequency) instead of being converted into an intermittent sound time interval. In this modification, as the distance between the player 10f of the through-pass recipient and the offside line 14 is smaller (larger), the pitch of the guidance sound to be heard by the player 10a is made higher (lower). If it does in this way, the change of the distance which approaches and leaves | separates can be alert | reported easily.

(15) In the fourth embodiment, a mixed sound of the first sound and the second sound that has undergone a change in the distribution of the fundamental frequency and the volume level of the left and right channels is used as a guide sound indicating the state of the driver 18 and the passenger 19. As output from both earphones 67L, 67R, 87L, 87R. However, separate guidance sounds may be sent to the driver 18 and the passenger 19. In this modified example, the operation amount and direction of the handling of the driver 18 and the weight movement of the passenger 19 are obtained based on the sum of the handling amount and the weight movement amount, and the obtained operation amount and direction are indicated. A guide sound is output from each of the earphones 67L, 67R, 87L, 87R.
For example, if the weight shift amount to the right of the passenger 19 is insufficient compared to the right handle amount of the driver 18 of the motorcycle with a side car turning to the right, the audio signal of one sound source (for example, having a certain period) Two kinds of guide sounds obtained by individually processing pure audio signals are output from the earphones 67L and 67R of the driver 18 and the earphones 87L and 87R of the passenger 19, respectively.
More specifically, the earphones 87L and 87R of the passenger 19 output a guidance sound that prompts further weight shift in the right direction. More specifically, while the weight transfer amount is insufficient with respect to the handling amount, an intermittent sound (pit, beep, beep) with the sound image localized to the left is output, and the number of pronunciations per unit time is It becomes shorter as the deficient amount of weight shift becomes smaller. Then, when the passenger 19 increases the weight shift amount in the right direction using the intermittent sound as a clue, and the weight shift amount becomes equal to the handling amount of the driver 18, the intermittent sounds output from the earphones 87L and 87R are continuous. It changes to sound (pea).
On the other hand, a guide sound that promotes relaxation of excessive handling in the right direction is output from the earphones 67L and 67R of the driver 18. More specifically, while the amount of handling is excessive relative to the amount of weight transfer, an intermittent sound (pit, beep, beep) with the sound image localized to the right is output, and the number of pronunciations per unit time is The shorter the excess amount, the shorter. Then, using the intermittent sound as a clue, the driver 18 loosens the rightward handling, and when the handling amount and the weight shift amount of the passenger 19 become equal, the intermittent sound output from the earphones 67L and 67R is a continuous sound (pee). ).
An overview of the above-described modified exercise support apparatus is as follows. “State detection means for detecting the state of each of the plurality of players, and an optimal exercise for the support target player that is at least a part of the plurality of players based on the states of the plurality of players detected by the state detection means. Guidance sound providing means for generating and providing the support target player with a guidance sound, wherein the state detection means is a first support target that is one of the two support target players. The amount and direction of handling of the player is detected as the state of the player, and the amount and direction of weight shift of the second support target player, which is the other player, are detected as the state of the player, and the guidance sound is provided. The means outputs a sound image in an operation direction that compensates for an excess or deficiency of the amount of handling relative to the amount of weight shift, or in a direction opposite to the operation direction. And providing the first support target player with a guide sound in which the number of pronunciations per unit time corresponds to the difference between the amount of weight shift and the amount of handling. An operation direction that compensates for the excess or deficiency of the amount of weight shift with respect to the amount of weight, or a guide sound in which a sound image is localized in a direction opposite to the operation direction, wherein the number of pronunciations per unit time and the amount of handling An exercise support apparatus that provides the second support target player with a guide sound corresponding to a difference from the amount of weight shift.
Further, in this modified example, a master-slave relationship is set between the driver 18 and the passenger 19, and for example, the only guidance sound processed so as to match the movement of the center of gravity of the passenger 19 with the handling of the driver 18 is notified to both of them. It may be. According to this, it becomes possible to simply and easily notify whether or not the handling of the driver 18 and the weight shift of the passenger 19 are in harmony.

(16) In the fourth embodiment, a guidance sound is output if the handling of the driver 18 and the weight movement direction of the passenger 19 match, and if not, the guidance sound is not output. May be switched in a binary manner.
(17) In the fourth embodiment, only the amounts are detected without detecting the direction of handling of the driver 18 and the weight shift of the passenger 19, and according to the difference between the handling amount of the driver 18 and the weight shift of the passenger 19. The number of pronunciations per unit time of the guidance sound to be heard by both may be changed. Even though the motorcycle with a side car is turning to the left (right), it is normal for the passenger 19 to move in the opposite direction, that is, the direction of movement of the two is completely reversed. Therefore, it is possible to support the turning training by presenting only the difference between the handling amount and the weight shift amount with the guidance sound.
(18) In the third embodiment, instead of the ball position detection unit 50, a ball position image analysis unit 50 ′ for analyzing a video (moving image) obtained by shooting the ball 13 from a plurality of directions and specifying the position of the ball 13 is provided. May be.
