  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, embodiment described below is embodiment at the time of applying this invention to the exercise content production | generation system which produces | generates the exercise content for supporting exercise. The exercise content includes video and audio for supporting exercise.

[1. Configuration of Exercise Content Generation System 1]
First, the configuration of the exercise content generation system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a schematic configuration example of an exercise content generation system 1 according to the present embodiment. As shown in FIG. 1, the exercise content generation system 1 includes a distribution server 2 and one or more output terminals 5. The distribution server 2 and the output terminal 5 can be connected via the network 10. The network 10 includes, for example, the Internet. A database 3 is connected to the distribution server 2. Information relating to exercise and information relating to music are registered in the database 3. The distribution server 2 distributes information registered in the database 3 to the output terminal 5 periodically or in response to a request from the output terminal 5.

  The output terminal 5 is a terminal device installed in the facility 4, for example. The output terminal 5 is an example of an information processing apparatus of the present invention. The output terminal 5 is used by a user 41 of the facility 4. The facility 4 may be a sports facility, for example. The user 41 receives an exercise lesson at the sports facility. An exercise lesson is a lesson composed of a plurality of exercises and singing. The output terminal 5 in this case may be a personal computer, for example. The facility 4 may be a karaoke store, for example. In the karaoke store, the user 41 sings karaoke music. The output terminal 5 in this case is a karaoke apparatus, for example. Hereinafter, a case where the facility 4 is a sports facility will be described as an example.

  The output terminal 5 can be connected to the monitor 57. The monitor 57 may be a display device including a plurality of speakers 64 and a display 67. In this case, the output terminal 5 can be connected to the display 67. The output terminal 5 can be connected to a speaker 64. The display 67 is an example of display means of the present invention. The speaker 64 is an example of the output means of the present invention. When the output terminal 5 outputs an audio signal to the monitor 57, music or the like is output from the speaker 64. When the output terminal 5 outputs a video signal to the monitor 57, an exercise video or the like is displayed on the display 67. The motion video is a moving image that shows a figure 83 that performs the motion. The figure 83 is a virtual object in the form of, for example, a person, an animal, a virtual creature, or a robot. The figure 83 is arranged in a three-dimensional virtual space. When the facility 4 is a karaoke store, the display 67 displays, for example, a figure 83 that performs a dance operation corresponding to a karaoke song. An exercise image is an example of an image in the present invention. The output terminal 5 outputs a signal so that the music output from the speaker 64 and the movement of the figure 83 displayed on the display 67 are synchronized. Outputting music and motion video is an example of outputting motion content. The user 41 can sing the music while listening to the music output from the speaker 64. Further, the user 41 can exercise while watching the figure 83 displayed on the display 67 while listening to the music. Thereby, the user 41 can exercise while singing. The operator 42 can operate the output terminal 5 using the remote controller 66 or the like. The user 41 and the operator 42 may be the same person. When the facility 4 is a sports facility, the operator 42 may be an instructor, for example.

  When performing an exercise lesson, the user 41 can wear a plurality of acceleration sensors AS, for example. The acceleration sensor AS detects the acceleration of a predetermined body part of the user 41 when the user 41 is exercising. For example, the user 41 may wear the acceleration sensor AS on the wrist, elbow, shoulder, foot base, knee, ankle, or the like. The output terminal 5 calculates the evaluation value of the exercise of the user 41 and the calorie consumption of the user 41 due to the exercise based on the acceleration detected by the acceleration sensor AS. For example, the output terminal 5 may increase the evaluation value as the exercise motion of the user 41 is closer to the exercise motion of the figure 83 displayed on the display 67. For example, a video camera for photographing the user 41 when the user 41 is exercising may be installed in the facility 4 instead of the user 41 wearing the acceleration sensor AS. In this case, the output terminal 5 may calculate the evaluation value and the calorie consumption based on the video of the user 41 taken by the video camera. Further, when performing an exercise lesson, the user 41 can sing the microphone 68. The output terminal 5 calculates the evaluation value of the user 41 singing and the calorie consumption of the user 41 due to the singing based on the singing voice input to the microphone 68. For example, the output terminal 5 may increase the evaluation value as the pitch of the singing voice of the user 41 is closer to the pitch of the singing voice serving as a reference corresponding to the music output by the speaker 64. When the exercise lesson ends, the output terminal 5 causes the display 67 to display the exercise evaluation value, the calorie consumption by exercise, the evaluation value of singing, and the calorie consumption by singing.

[2. Exercise content]
The exercise content output by the monitor 57 when an exercise lesson is performed includes at least music and an exercise video. The music is composed of a plurality of performance parts. Music is output from the speaker 64 in the order of the parts according to the composition of the music. For example, music may be output in the order of A melody, B melody, rust, interlude, A melody, B melody, rust and the like. A plurality of music pieces may be sequentially output from the speaker 64 in one exercise lesson. An exercise motion is assigned to each performance part constituting the music. When outputting the exercise content, the output terminal 5 causes the display 67 to display an exercise image in which the figure 83 performs the exercise operation assigned to the performance part output by the speaker 64.

  The exercise operation is an operation for training the body, for example. Examples of the exercise operation include a gymnastic operation and a dance operation. The gymnastic exercise is, for example, an exercise performed for promoting health, strengthening physical strength, strengthening muscle strength, and the like. Examples of gymnastic exercises include aerobic exercise, anaerobic exercise, and stretching. Examples of the aerobic exercise include march and front lunge. Examples of the anaerobic exercise include a shoulder press and a chest press. Examples of stretching exercises include upper arm stretching and neck stretching. The dance motion is a motion that is choreographed to the music to dance to the music.

  The output terminal 5 can include narration for instructing the motion of the user 41, song lyrics, sound effects, and the like in the exercise content. The narration explains, for example, an exercise operation or instructs how to move the body. Narration includes narration text and narration audio. The narration text is a text indicating the narration. Narration voice is voice that indicates narration. There are lyrics telop and guide vocal as lyrics. Lyric telop is a character indicating lyrics. The guide vocal is, for example, a voice that a singer or the like sings the lyrics of a song at an exemplary pitch. The sound effect is, for example, a sound for raising the mood of the user 41 performing an exercise lesson. For example, the sound effect may be a clapping sound, a clapping sound, a cheering sound, or the like. There are basic sound effects and additional sound effects as sound effects. When the sound effect is output, at least the basic sound effect is output among the basic sound effect and the additional sound effect. The additional sound effects are sound effects that are output in addition to the basic sound effects. When the mood of the user 41 is further increased, both basic sound effects and additional sound effects are output. The type of sound effect included in the basic sound effect and the type of sound effect included in the additional sound effect may be different. For example, the basic sound effects may include clapping sounds, and the additional sound effects may include clapping sounds and cheers. In addition, all or part of the types of included sound effects may be the same between the basic sound effects and the additional sound effects.

  Elements that determine the content of an exercise lesson include, for example, music sung by the user 41 and a plurality of exercise operations performed by the user 41. The user 41 gets used to the exercise lesson by performing the exercise lesson with the same content many times. By getting used to the user 41 exercise lesson, the user 41 becomes proficient in the exercise operation constituting the exercise lesson. The degree of skill of exercise of the user 41 is referred to as exercise level. If the user 41 gets used to the exercise lesson by performing the exercise lesson with the same content, the user 41 may get bored with the exercise lesson. Therefore, the output terminal 5 produces an effect so that the user can enjoy exercising and singing according to the user's exercise level even if the exercise lesson has the same content. Information used for production includes narration, lyrics, and sound effects.

  First, the output terminal 5 determines the exercise level of the user 41 who performs an exercise lesson. For example, the output terminal 5 may determine the exercise level based on the past exercise evaluation value of the user 41. In this case, the output terminal 5 may increase the exercise level as the evaluation value increases. Further, the output terminal 5 may determine the exercise level based on, for example, the number of times that the user 41 has performed an exercise lesson. In this case, the output terminal 5 may increase the exercise level as the number of times increases. The output terminal 5 may determine the exercise level selected by the user 41 as the exercise level of the user 41, for example. In this embodiment, there are three levels of exercise. For example, the exercise level may be beginner, intermediate and advanced. Intermediate level has higher exercise level than beginner level. Advanced level is higher than intermediate level. The beginner is an example of the first level in the present invention. Intermediate is an example of the second level in the present invention. Advanced is an example of the third level in the present invention. In the present embodiment, the exercise level is three stages, but the exercise level may be two stages or four or more stages.

  When the exercise level is determined, the output terminal 5 sets an exercise lesson according to the exercise level. The exercise lesson setting is to determine at least whether or not to output narration, whether or not to output lyrics, and whether or not to output sound effects. The exercise lesson setting also determines the content of exercise content. When the exercise level is beginner level, the output terminal 5 outputs a narration. Thereby, the output terminal 5 can assist the user 41 in acquiring exercise when the exercise level is low. On the other hand, the output terminal 5 does not output lyrics and sound effects. Since information that is not necessary for learning exercises is not output, the user 41 can concentrate on learning exercises.

  When the exercise level is intermediate, the output terminal 5 outputs lyrics. Thereby, the user 41 who has become accustomed to exercise can learn singing while exercising. On the other hand, the output terminal 5 does not output narration and sound effects. Narration is unnecessary for the user 41 who has become accustomed to the exercise. In addition, since information that is not necessary for learning a song is not output, the user 41 can concentrate on learning a song while exercising.

  When the exercise level is advanced, the output terminal 5 outputs lyrics and sound effects. Thereby, when the user 41 who has become more accustomed to exercise and used to singing exercises while singing, the user 41 can be excited. On the other hand, the output terminal 5 does not output narration. Narration is unnecessary for the user 41 who is used to exercise.

  FIG. 2A is a diagram illustrating a setting example of an exercise lesson. FIG. 2A shows an example in which an exercise lesson is set according to a combination of exercise load and exercise level. A combination of exercise load and exercise level is called a content type. The content type indicates, for example, the type or type of exercise content. The exercise load is, for example, a load applied to the body of the user 41 due to an exercise operation. For example, it is assumed that a step motion is assigned to a certain performance part. For example, the output terminal 5 may display the motion image on the display 67 so that the motion of the figure 83 performing the step motion increases as the exercise load increases. The greater the movement, the greater the load on the body. The exercise load may be selected by the user 41, for example. In the example of FIG. 2A, there are load 1, load 2, and load 3 as exercise loads. The load 2 has a greater exercise load than the load 1, and the load 3 has a greater exercise load than the load 2. Between the load 1, the load 2 and the load 3, the types of exercise motions assigned to the performance part are the same. For example, it is assumed that a step motion is assigned to a certain performance part. In this case, a step motion of load 1, a step motion of load 2, or a step motion of load 3 is assigned. In this manner, step motions having the same motion motion but step motions having different loads are assigned. Moreover, although the kind of step exercise | movement is the same, the step exercise | movement from which an exercise | movement action differs with load may be allocated.

  The output terminal 5 sets exercise lessons according to the content type. Specifically, as shown in FIG. 2 (A), the output terminal 5 displays the exercise load, whether or not narration text is displayed, whether or not narration voice is output, whether or not lyric telop is displayed, and whether or not guide vocal is output. Whether to output basic sound effects and whether to output additional sound effects is determined. In FIG. 2A, “◯” indicates that there is output or display, and “X” indicates that there is no output or display. As an exercise type, for example, as shown in FIG. 2 (A), Load 1 beginner, Load 1 intermediate, Load 1 advanced, Load 2 intermediate, Load 2 intermediate, Load 2 advanced, Load 3 intermediate, Load 3 intermediate, Load 3 There is a senior. A plurality of exercise types having the same exercise level differ only in exercise load, and other contents are the same. As an example, the load 1 elementary class, the load 2 elementary class, and the load 3 elementary class differ only in the exercise load. Therefore, only beginner, intermediate, and advanced levels will be explained.

  In the beginner's class, the display of the narration text and the output of the narration voice are set to “present”. The display of lyrics telop, the output of guide vocals, the output of basic sound effects and the output of additional sound effects are set to “none”. In the intermediate level, the display of the lyrics telop and the output of the guide vocal are set to “Yes”. The display of the narration text, the output of the narration sound, the output of the basic sound effect, and the output of the additional sound effect are set to “none”. In the advanced case, the display of lyrics telop, the output of basic sound effects, and the output of additional sound effects are set to “Yes”. The display of the narration text, the output of the narration voice, and the output of the guide vocal are set to “none”. There is a probability that the user 41 with an advanced exercise level has mastered singing to some extent. Therefore, even if the guide vocal is not output, the user 41 can sing if he / she sees the lyrics. Moreover, the user 41 who is used to singing can sing while exercising without worrying about guide vocals.

  FIG. 2B is a diagram illustrating another setting example of an exercise lesson. FIG. 2B shows an example in which each exercise level is further divided into two exercise levels. In the example of FIG. 2B as well, the plurality of exercise types having the same exercise level are the same except for the exercise load. The exercise level includes, for example, beginner A, beginner B, intermediate A, intermediate B, advanced A, and advanced B. Beginner B has a higher level of exercise than Beginner A. Intermediate B has a higher exercise level than Intermediate A. Advanced B has a higher exercise level than Advanced A. Beginner A is an example of the sixth level in the present invention. Beginner B is an example of the seventh level in the present invention. Intermediate A is an example of the fourth level in the present invention. Intermediate B is an example of the fifth level in the present invention. In addition, beginner, intermediate and advanced may be divided into three or more exercise levels.

  In the case of beginner A, the display of narration text and the output of narration voice are set to “present”. The display of lyrics telop, the output of guide vocals, the output of basic sound effects and the output of additional sound effects are set to “none”. In the case of Beginner B, the narration voice output is set to “Yes”. Also, the display of narration text, the display of lyrics telop, the output of guide vocals, the output of basic sound effects and the output of additional sound effects are set to “none”. When the exercise level rises from beginner A to beginner B and the user 41 gets used to the exercise to some extent, it is enough to output either narration text or narration voice. Here, it is possible to increase the amount of narration information transmitted to the user 41 in the voice rather than in the text. Therefore, narration text is not displayed and narration voice is output. Thereby, the user 41 can concentrate on an exercise | movement, listening to a narration audio | voice by not seeing a narration sentence.

  In the case of Intermediate A, the display of the lyrics telop and the output of the guide vocal are set to “Yes”. The display of the narration text, the output of the narration sound, the output of the basic sound effect, and the output of the additional sound effect are set to “none”. In the case of Intermediate B, the display of the lyrics telop is set to “Yes”. The display of narration text, the output of narration voice, the output of guide vocals, the output of basic sound effects, and the output of additional sound effects are set to “none”. The exercise level rises from intermediate A to intermediate B, and the user 41 learns to sing. Then, even if there is no guide vocal, the user 41 can sing with a certain correct pitch while watching the lyrics. Moreover, the user 41 who has become accustomed to singing can sing while exercising without worrying about guide vocals.

  In the case of Advanced A, the display of lyrics telop and the output of basic sound effects are set to “Yes”. The display of the narration text, the output of the narration voice, the output of the guide vocal and the output of the additional sound effect are set to “none”. In the case of Advanced B, the display of lyrics telop, the output of basic sound effects, and the output of additional sound effects are set to “Yes”. The display of the narration text, the output of the narration voice, and the output of the guide vocal are set to “none”. In the advanced level, sound effects increase as the exercise level increases. Thereby, the user's 41 mood can be raised in steps.

  Next, an example of determining the actual content of exercise content according to the exercise level will be described with reference to FIG. In this embodiment, the output terminal 5 calculates the exercise evaluation value of the user 41 every time the output of one performance part is completed when music is being output in the exercise lesson. The output terminal 5 determines the exercise level based on the evaluation value. Then, the output terminal 5 determines the content of the exercise content while the next performance part is output based on the exercise level. For example, it is assumed that the content of exercise content is determined according to the setting example illustrated in FIG. The output terminal 5 may determine the exercise level at a timing different from the timing at which the performance part output ends, for example. The output terminal 5 may determine the exercise level only when an exercise lesson is started, for example. Then, the CPU 51 may determine the content of the exercise content while all performance parts constituting the music are sequentially output based on the exercise level determined first.

  For a certain music X, for example, it is assumed that performance parts are output in the order of A melody 1, B melody 1, chorus 1, interlude 1, A melody 2, B melody 2, chorus 2. In the present embodiment, an exercise operation corresponding to a combination of a music piece and a performance part type is predetermined. In the example of FIG. 3, the exercise action 1 is assigned to the A melody 1 and the A melody 2 of the music piece X. The motion motion 2 is assigned to B melody 1 and B melody 2 of the music piece X. A movement motion 3 is assigned to the chorus 1 of the music piece X. The movement 1 is assigned to the interlude 1 of the music piece X. The movement 2 is assigned to the chorus 2 of the music piece X. The movement movement of the last chorus part in the music order in the music may be partially different from the movement movement of other chorus parts. In the present embodiment, for each combination of exercise motion and exercise load, there are narration text, narration sound, basic sound effect, and additional sound effect corresponding to the combination. For each performance part, there is a lyrics telop and a guide vocal corresponding to the performance part.

  FIG. 3A shows the content of the exercise content at the time when A melody 1 is output. When starting an exercise lesson, it is assumed that the operator 42 specifies, for example, the music piece X and the load 1 as the exercise load. When starting an exercise lesson, for example, it is assumed that the output terminal 5 determines a preset exercise level as the exercise level of the user 41 performing the exercise lesson. For example, the output terminal 5 determines Intermediate B as the exercise level. When A melody 1 is output and an exercise image of exercise operation 1 with an exercise load of load 1 is displayed, the output terminal 5 displays a telop of lyrics corresponding to the A melody 1. On the other hand, the output terminal 5 does not output narration text, narration voice, guide vocal, basic sound effects, and additional sound effects.

  FIG. 3B shows the content of the exercise content at the time when the B melody 1 is output. When the output of the A melody 1 is completed, the output terminal 5 calculates an evaluation value of the exercise action 1 performed by the user 41. Then, it is assumed that the output terminal 5 determines the beginner level B as the exercise level based on the evaluation value. In this case, when the B melody 1 is output and the motion image of the motion motion 2 in which the motion load is the load 1 is displayed, the output terminal 5 outputs the narration sound corresponding to the motion motion 2 of the load 1. On the other hand, the output terminal 5 does not output narration sentences, lyrics telops, guide vocals, basic sound effects, and additional sound effects.

  The HDD 7 further stores various programs such as an OS, an exercise support program, a 3D engine, and a music sequencer. The exercise support program is a program for supporting the exercise of the user 41. The exercise support program causes the CPU 51 as a computer to execute at least a determination step, a first control step, a second control step, a third control step, a fourth control step, and a fifth control step.

As shown in FIG. 4B, the CPU 51 acquires the song ID of the song used for the exercise lesson (step S11). Specifically, the CPU 51 displays a list of music pieces on the display 67. For example, the operator 42 operates the remote controller 66 to select music from the list. The CPU 51 specifies the music ID of the music selected by the operator 42 based on the signal received from the remote controller 66 via the sensor information receiving unit 69.

  Next, the CPU 51 acquires an exercise load (step S12). Specifically, the CPU 51 displays a screen for selecting an exercise load. The operator 42 performs selection by operating the remote controller 66, for example. Then, the remote controller 66 transmits a signal corresponding to the operation. CPU 51 specifies an exercise load based on a signal received from remote controller 66.

  Next, the CPU 51 determines the exercise level of the user 41 performing the exercise lesson (step S13). For example, the CPU 51 determines the exercise level stored in the HDD 7 in advance for the user 41 who performs an exercise lesson.

  Next, the CPU 51 acquires a set value for an exercise lesson (step S14). Specifically, the CPU 51 generates a content type from the exercise load and the exercise level. Then, the CPU 51 acquires from the lesson setting table the exercise load corresponding to the content type, narration sentence presence / absence, narration voice presence / absence, lyrics presence / absence, guide vocal presence / absence, basic sound effect presence / absence, and additional sound effect presence / absence.

  Next, the CPU 51 generates lesson information (step S15). Specifically, the CPU 51 causes the HDD 7 to store lesson information including the music ID acquired in step S11. Next, the CPU 51 reads the performance part start event having the first performance order from the music data corresponding to the acquired music ID. Next, the CPU 51 acquires a part ID and a part type from the acquired performance part start event. Next, the CPU 51 generates part information including the acquired part ID and part type. Next, the CPU 51 generates a motion ID from the exercise load, the music ID, and the part type. Next, the CPU 51 adds the generated motion ID to the part information. Next, the CPU 51 adds the acquired narration text presence / absence, narration voice presence / absence, lyrics presence / absence, guide vocal presence / absence, basic sound effect presence / absence, and additional sound effect presence / absence to the part information.

  When the narration text presence / absence is set to “present”, the CPU 51 acquires the narration text ID corresponding to the motion ID from the HDD 7 and adds it to the part information. When the narration voice presence / absence is set to “present”, the CPU 51 acquires the narration voice ID corresponding to the motion ID from the HDD 7 and adds it to the part information. When the presence / absence of lyrics is set to “Yes”, the CPU 51 acquires the lyrics ID corresponding to the music ID and the part ID from the HDD 7 and adds them to the part information. When the presence / absence of the guide vocal is set to “Yes”, the CPU 51 acquires the guide vocal ID corresponding to the music ID and the part ID from the HDD 7 and adds them to the part information. When the presence / absence of the basic sound effect is set to “present”, the CPU 51 acquires the basic sound effect ID corresponding to the motion ID from the HDD 7 and adds it to the part information. When the presence / absence of the additional sound effect is set to “present”, the CPU 51 acquires the additional sound effect ID corresponding to the motion ID from the HDD 7 and adds it to the part information. CPU51 adds the part information which added the required information to lesson information. When finishing the process of step S15, the CPU 51 ends the lesson generation process.

  FIG. 5A is a flowchart illustrating an example of a lesson execution process performed by the CPU 51 of the output terminal 5. As shown in FIG. 5A, the CPU 51 performs initial setting (step S21). Specifically, the CPU 51 causes the display 67 to display a message instructing the user 41 to wear the sensor AS and stand still in a specified posture. The specified posture may be a careful posture, for example. For example, the HDD 7 stores in advance the coordinates in the three-dimensional space of each body part of the user 41 in a prescribed posture. After a predetermined time has elapsed since the message was displayed, the CPU 51 stores the coordinates stored in the HDD 7 in the RAM 53 as the initial values of the coordinates of the body part of the user 41. Next, the CPU 51 acquires the current time from the clock function. Then, the CPU 51 stores the current time in the RAM 53 as the music reproduction start time. Further, the CPU 51 stores the current time in the RAM 53 as the reproduction start time of the performance part having the first performance order. Further, the CPU 51 acquires part information of the performance part having the first performance order from the generated lesson information. Further, the CPU 51 acquires the tempo of the music from the music data corresponding to the music ID included in the lesson information.

  CPU51 reproduces | regenerates exercise | movement content after finishing the process of step S21. First, the CPU 51 executes a motion video display process by the 3D engine (step S22). Specifically, the CPU 51 generates a still image of the motion video based on the motion data corresponding to the motion ID included in the acquired part information. At this time, the CPU 51 determines a still image to be generated based on the tempo of the music and the elapsed time from the playback start time of the performance part to the current time. The CPU 51 outputs the generated still image to the display control unit 56. The display control unit 56 outputs a video signal corresponding to the still image to the display 67. As a result, an exercise image in which the figure 83 operates is displayed on the display 67.

  Next, the CPU 51 executes a lyrics display process (step S23). Specifically, the CPU 51 determines whether or not the presence / absence of lyrics included in the acquired part information is set to “Yes”. At this time, when the presence / absence of the lyrics is set to “none”, the CPU 51 ends the lyrics display process without displaying the lyrics. On the other hand, when the presence / absence of the lyrics is set to “Yes”, the CPU 51 displays the lyrics telop based on the lyrics data corresponding to the lyrics ID included in the part information. At this time, the CPU 51 determines the text to be displayed from the text included in the lyrics data based on the elapsed time from the playback start time of the performance part to the current time. Then, the CPU 51 outputs the determined text to the display control unit 56. In this case, the display control unit 56 combines the character indicated by the text and the still image of the motion video. Then, the CPU 51 outputs a video signal corresponding to the synthesized image to the display 67. As a result, the figure 83 and the lyrics that move are displayed on the display 67.

  Next, the CPU 51 executes a narration text display process (step S24). Specifically, the CPU 51 determines whether or not the presence of narration text included in the acquired part information is set to “Yes”. At this time, if the narration text presence / absence is set to “none”, the CPU 51 ends the narration text display process without displaying the narration text. On the other hand, when the presence / absence of the narration text is set to “present”, the CPU 51 displays the narration text based on the narration text data corresponding to the narration text ID included in the part information. At this time, the CPU 51 determines the text to be displayed from the text included in the narration text data based on the elapsed time from the playback start time of the performance part to the current time. Then, the CPU 51 outputs the determined text to the display control unit 56. In this case, the display control unit 56 combines the character indicated by the text and the still image of the motion video. Then, the CPU 51 outputs a video signal corresponding to the synthesized image to the display 67. As a result, the figure 83 and the narration text are displayed on the display 67.

  Next, the CPU 51 executes a music reproduction process by the music sequencer (step S25). Specifically, the CPU 51 outputs music based on music data corresponding to the music ID included in the generated lesson information. At this time, the CPU 51 reads an event corresponding to the elapsed time from the music reproduction start time to the current time from the music data. And CPU51 controls the output of the audio | voice signal by the audio | voice output part 63 based on the read event. Thereby, the CPU 51 causes the audio output unit 63 to output the audio signal of the music from the speaker 64. Then, music is output from the speaker 64. In the music data, for example, a set of delta time and event is described. The delta time indicates the time from when a certain event is output until the next event is output. Therefore, for example, the CPU 51 determines the timing for reading an event from music data according to the delta time and the music tempo.

  Next, the CPU 51 executes a guide vocal reproduction process (step S26). Specifically, the CPU 51 determines whether or not the guide vocal presence / absence included in the acquired part information is set to “present”. At this time, when the presence / absence of the guide vocal is set to “none”, the CPU 51 ends the guide vocal reproduction process without outputting the guide vocal. On the other hand, when the presence / absence of the guide vocal is set to “Yes”, the CPU 51 outputs the guide vocal based on the guide vocal data corresponding to the guide vocal ID included in the part information. At this time, the CPU 51 reads from the guide vocal data the data portion corresponding to the elapsed time from the playback start time of the performance part to the current time. And CPU51 controls the output of the audio | voice signal by the audio | voice output part 63 based on the read data part. In this case, the audio output unit 63 combines the audio signal of the guide vocal and the audio signal of the music. Then, the audio output unit 63 outputs the synthesized audio signal to the speaker 64. As a result, the music piece and the guide vocal are output from the speaker 64.

  Next, the CPU 51 executes a narration voice reproduction process (step S27). Specifically, the CPU 51 determines whether or not the narration voice presence / absence included in the acquired part information is set to “present”. At this time, if the presence / absence of the narration sound is set to “none”, the CPU 51 ends the narration sound reproduction process without outputting the narration sound. On the other hand, when the presence / absence of the narration voice is set to “present”, the CPU 51 outputs the narration voice based on the narration voice data corresponding to the narration voice ID included in the part information. At this time, the CPU 51 reads from the narration audio data the data portion corresponding to the elapsed time from the playback start time of the performance part to the current time. And CPU51 controls the output of the audio | voice signal by the audio | voice output part 63 based on the read data part. In this case, the audio output unit 63 synthesizes the audio signal of the narration audio and the audio signal of the music. Then, the audio output unit 63 outputs the synthesized audio signal to the speaker 64. Thereby, music and narration sound are output from the speaker 64.

  Next, the CPU 51 executes sound effect reproduction processing (step S28). Specifically, the CPU 51 determines whether or not the presence of the basic sound effect included in the acquired part information is set to “present”. At this time, if the presence / absence of the basic sound effect is set to “none”, the CPU 51 ends the sound effect reproduction process without outputting the basic sound effect. On the other hand, when the presence / absence of the basic sound effect is set to “present”, the CPU 51 outputs the basic sound effect based on the basic sound effect data corresponding to the basic sound effect ID included in the part information. At this time, the CPU 51 reads from the basic sound effect data a data portion corresponding to the elapsed time from the playback start time of the performance part to the current time. And CPU51 controls the output of the audio | voice signal by the audio | voice output part 63 based on the read data part. In this case, the audio output unit 63 combines the audio signal of the basic sound effect and the audio signal of the music. Then, the audio output unit 63 outputs the synthesized audio signal to the speaker 64. As a result, music and basic sound effects are output from the speaker 64. Further, the CPU 51 processes the additional sound effects in the same manner as the basic sound effects. Thereby, when the presence / absence of the additional sound effect is set to “present”, the music piece and the additional sound effect are output from the speaker 64.

  Next, the CPU 51 determines whether or not it is the acquisition timing of the song data and exercise data of the user 41 (step S29). Singing data is the pitch value and volume of the singing voice of the user 41. The exercise data is the coordinates of each body part of the user 41 in the three-dimensional space and the movement amount of each body part. For example, the user 41 acquires song data and exercise data every time a preset time interval elapses. At this time, if the CPU 51 determines that it is not the acquisition timing (step S29: NO), the process proceeds to step S32. On the other hand, when the CPU 51 determines that it is the acquisition timing (step S29: YES), the CPU 51 proceeds to step S30.

  In step S <b> 30, the CPU 51 acquires the song data of the user 41. Specifically, the CPU 51 analyzes the voice signal input from the microphone 68 and acquires the pitch value and volume of the singing voice. Then, the CPU 51 stores the acquired pitch value and volume in the RAM 53 in association with the elapsed time from the music playback start time. Next, the CPU 51 acquires exercise data of the user 41 (step S31). Specifically, the CPU 51 acquires acceleration information transmitted from each acceleration sensor AS via the sensor information receiving unit 69. Next, the CPU 51 calculates the coordinates and movement amount of each body part of the current user 41 based on the acquired acceleration information and the coordinates of each body part of the user 41 acquired before the set time interval. Then, the CPU 51 stores the calculated coordinates and movement amount in the RAM 53 in association with the motion ID included in the part information and the elapsed time from the playback start time of the performance part. The coordinates of each body part of the user 41 are an example of second motion information in the present invention.

  Next, the CPU 51 executes a lesson update process (step S32). In the lesson update process, the CPU 51 again determines the exercise level of the user 41 when it is time to update the lesson information. Then, the CPU 51 updates the lesson information based on the new exercise level. The timing at which the lesson information is updated is, for example, the timing at which the performance part is switched. Details of the lesson update process will be described later.

  Next, the CPU 51 determines whether or not the reproduction of the exercise content has ended (step S33). For example, if an event indicating that the end of music data has been detected is output from the music sequencer, the CPU 51 determines that the reproduction of the exercise content has ended. At this time, if the CPU 51 determines that the reproduction of the exercise content has not ended (step S33: NO), the CPU 51 proceeds to step S22. On the other hand, when the CPU 51 determines that the reproduction of the exercise content has ended (step S33: YES), the lesson execution process ends.

  FIG. 5B is a flowchart illustrating an example of a lesson update process performed by the CPU 51 of the output terminal 5. As shown in FIG. 5B, the CPU 51 determines whether it is the update timing of the lesson information (step S41). For example, the CPU 51 may determine that it is the update timing of lesson information when a performance part start event is output from the music sequencer. At this time, if the CPU 51 determines that it is not the update timing (step S41: NO), it ends the lesson update process. On the other hand, if the CPU 51 determines that it is the update timing (step S41: YES), it proceeds to step S42.

  In step S <b> 42, the CPU 51 calculates an evaluation value of the fate motion assigned to the performance part whose output has been terminated by switching the performance part. Specifically, the CPU 51 acquires the motion ID from the part information of the performance part that has been output. Next, the CPU 51 calculates the difference between the coordinates of each body part of the user 41 corresponding to the motion ID and the coordinates of each body part registered in the teacher coordinate data corresponding to the motion ID for each elapsed time. . Thus, the CPU 51 compares the coordinates of each body part of the user 41 with the coordinates of each body part registered in the teacher coordinate data. Next, the CPU 51 determines whether or not the coordinate difference is equal to or less than the exercise threshold stored in the HDD 7 in advance. And CPU51 counts the number of the coordinates of the body part of the user 41 whose difference is below an exercise | movement threshold value. Next, the CPU 51 calculates the ratio of coordinates whose difference is equal to or less than the exercise threshold by dividing the number of coordinates whose difference is equal to or less than the exercise threshold by the total number of coordinates of the body part of the user 41. Then, the CPU 51 calculates an evaluation value by multiplying the calculated ratio by 100. Next, the CPU 51 determines an exercise level based on the calculated evaluation value (step S43). For example, the CPU 51 increases the exercise level as the evaluation value increases.

  Next, the CPU 51 reacquires the exercise lesson setting value (step S44). Specifically, the CPU 51 generates a content type from the lesson setting table based on the exercise load acquired in the lesson generation process and the exercise level determined in step S43. Then, the CPU 51 acquires from the lesson setting table the exercise load corresponding to the content type, narration sentence presence / absence, narration voice presence / absence, lyrics presence / absence, guide vocal presence / absence, basic sound effect presence / absence, and additional sound effect presence / absence.

  Next, the CPU 51 updates lesson information (step S45). Specifically, the CPU 51 acquires the part ID and the part type from the performance part start event output from the music sequencer. Next, the CPU 51 generates part information and adds it to the lesson information. The part information generation method is the same as that in step S15 of the lesson generation process. Next, the CPU 51 stores it in the RAM 53 as the playback start time of the next performance part. When finishing the process of step S45, the CPU 51 ends the lesson update process. In the lesson execution process, the CPU 51 executes steps S22 to S31 based on the newly added part information and the playback start time of the next performance part.

  FIG. 5C is a flowchart illustrating an example of a lesson evaluation process performed by the CPU 51 of the output terminal 5. As shown in FIG.5 (C), CPU51 calculates the evaluation value of a song (step S51). Specifically, the CPU 51 calculates the difference between the pitch value of the singing voice of the user 41 stored in the RAM 53 and the pitch value registered in the teacher pitch data corresponding to the music ID included in the lesson information. Calculate every hour. Next, the CPU 51 determines whether or not the pitch value difference is equal to or less than the singing threshold value stored in advance in the HDD 7. And CPU51 counts the number of the pitch values of the user 41 whose difference is below a song threshold value. Next, the CPU 51 calculates the ratio of the pitch values whose difference is equal to or less than the singing threshold value by dividing the number of pitch values whose difference is equal to or less than the singing threshold value by the total number of pitch values of the user 41. Then, the CPU 51 calculates an evaluation value by multiplying the calculated ratio by 100.

  Next, the CPU 51 calculates an exercise evaluation value (step S52). Specifically, the CPU 51 calculates the difference between the coordinates of each body part of the user 41 stored in the RAM 53 and the coordinates of each body part registered in the teacher coordinate data for each elapsed time. At this time, the CPU 51 uses teacher pitch data corresponding to the same motion ID as the motion ID associated with the coordinates of the body part of the user 41. Next, the CPU 51 determines whether or not the coordinate difference is equal to or less than the exercise threshold stored in the HDD 7 in advance. And CPU51 counts the number of the coordinates of the body part of the user 41 whose difference is below an exercise | movement threshold value. Next, the CPU 51 calculates the ratio of coordinates whose difference is equal to or less than the exercise threshold by dividing the number of coordinates whose difference is equal to or less than the exercise threshold by the total number of coordinates of the body part of the user 41. Then, the CPU 51 calculates an evaluation value by multiplying the calculated ratio by 100.

  Next, the CPU 51 calculates calories burned by singing (step S53). Specifically, the CPU 51 determines the calorie corresponding to the volume for each volume of the singing voice of the user 41 stored in the RAM 53. At this time, the CPU 51 increases the calorie as the volume increases. And CPU51 calculates the calculated total value of calories as calorie consumption by singing.

  Next, the CPU 51 calculates calorie consumption due to exercise (step S54). Specifically, the CPU 51 determines a calorie corresponding to the movement amount for each movement amount of each body part of the user 41 stored in the RAM 53. At this time, the CPU 51 increases the calorie as the movement amount increases. And CPU51 calculates the total value of the calculated calorie as calorie consumption by exercise.

  Next, the CPU 51 causes the display 67 to display the evaluation value and the calorie consumption calculated in steps S51 to S54 (step S55). When finishing the process of step S55, the CPU 51 ends the lesson evaluation process.

  As described above, according to the present embodiment, the CPU 51 determines the exercise level of the user 41. Next, when the exercise level is an elementary level, the CPU 51 performs at least one of displaying a narration sentence and outputting a narration voice. Further, when the exercise level is intermediate, the CPU 51 performs at least one of displaying a lyrics telop and outputting a guide vocal. Further, when the exercise level is advanced, the CPU 51 performs at least one of displaying a telop of lyrics and outputting a guide vocal, and outputs a sound effect. Therefore, according to the exercise level of the user 41, it can produce so that the user 41 can perform exercise and singing while having fun.

  In the present embodiment, the output terminal 5 determines the exercise level every time the output of one performance part is completed in the exercise lesson. That is, the output terminal 5 dynamically changes the exercise level during the exercise lesson. However, the output terminal 5 does not have to change the exercise level during an exercise lesson, for example. Specifically, in step S13 of the lesson generation process shown in FIG. 4B, the output terminal 5 determines an exercise level to be applied throughout the exercise lesson. For example, the output terminal 5 may determine the exercise level based on the past exercise evaluation value of the user 41. The output terminal 5 may cause the user 41 to select an exercise level, for example. Next, the output terminal 5 acquires a setting value corresponding to the determined exercise level (step S14), and generates lesson information based on the acquired setting value (step S15). At this time, the output terminal 5 generates lesson information including part information of all performance parts constituting the music. That is, the output terminal 5 determines the content of the exercise content for all performance parts constituting the music according to the exercise level determined in step S13. In the lesson execution process shown in FIG. 5A, the output terminal 5 does not execute the lesson update process in step S32. In the lesson execution process, the output terminal 5 acquires part information of the performance part in the next performance order from the lesson information every time the performance part is switched. Then, the output terminal 5 controls the output of the exercise content based on the acquired part information.

  In the above embodiment, the information processing apparatus of the present invention is applied to the output terminal 5. However, the information processing apparatus of the present invention may be applied to the distribution server 2. For example, the distribution server 2 may determine the exercise level of the user 41 and generate lesson information. Then, the distribution server 2 may generate audio data and moving image data based on the lesson information. The audio data in this case is data for outputting music, guide vocals, narration audio, and sound effects. The moving image data is data for displaying exercise video, lyrics, and narration text. When the exercise lesson is performed, the distribution server 2 transmits the audio data and the moving image data to the output terminal 5 by, for example, a streaming method. As a result, the distribution server 2 causes the output terminal 5 to output the music and display the motion video. Further, the information processing apparatus of the present invention may be applied to the output terminal 5 and the distribution server 2. The output terminal 5 and the distribution server 2 may perform processing in cooperation.
