Description

  The present invention relates to a terminal device, a communication system, a determination result recording method for a terminal device, and a program for determining a human action such as dance of a dancer.

  Conventionally, a scoring device for scoring dancers' dances is known. For example, in patent document 1, a dancer is imaged with a camera and the position of a dancer's head, abdomen, and both hands is detected. The movement time of each part of the dancer (the length between the minimum or maximum values of the trajectory curve indicating the movement amount of each part), the rhythm of the accompaniment output from the music playback device (time interval of one beat), , And when these are in a predetermined relationship (1/3, 1/2, 1, 4/3, 3/2, 2, 3, 4,..., Etc.), it is determined that the sense of rhythm is good. .

JP 2002-35191 A

  However, since the technique of Patent Document 1 uses a camera to detect the movement of the dancer, it is necessary to secure the dedicated place and install the camera. When moving the place, the camera must be carried around. I must. For this reason, there exists a subject that it cannot be used easily.

  In addition, in situations such as clubs and music bars where people enjoy dancing to music that is played one after another, there is a desire to keep a record of which music the user danced to. This is synonymous with recording a favorite song on the premise that the diagram “Dancing to a song = I like the song” holds. However, conventionally, the only way to record a favorite song is to manually bookmark the song list by the user. However, it is difficult to operate bookmarks while dancing, and there is no credibility in the method of remembering the danced music and bookmarking it later.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a terminal device, a communication system, a determination result recording method for a terminal device, and a program capable of recording a user's favorite music without performing complicated operations. To do.

  The terminal device of the present invention includes a beat information acquisition unit that acquires beat information of a song, an operation detection unit that detects an operation of a user who owns the device, beat information, and a comparison result between detection values by the operation detection unit. According to the operation determination unit that determines whether or not the user is moving the body according to the music, a recording unit that records the information indicating the music in association with the identification information indicating the determination result of the operation determination unit, It is provided with.

  The determination result recording method of the terminal device according to the present invention includes a step of acquiring beat information of a song, a step of detecting a user's operation of own device, a comparison result of beat information and a user's operation detection value. Accordingly, the step of determining whether or not the user moves the body according to the music and the identification information indicating the determination result of whether or not the user moves the body according to the music are associated with the information indicating the music And a step of recording.

According to the configuration of the present invention, since the user's operation is detected by the terminal device, it is possible to easily perform the operation determination only by the terminal device, other than the dedicated place. Also, by comparing the beat information with the motion detection value, it is determined whether or not the user is moving with the music, and the determination result is recorded in association with the information indicating the music. You can easily record your favorite music without needing it.
Note that “having its own device” is a concept including that the user wears the terminal device or stores it in a pocket.
The “music beat information” refers to information indicating the beat position of the music. Furthermore, “acquisition of beat information” may be obtained by acquiring beat information by collecting music or acquiring beat timing, or by obtaining BPM (Beats Per Minute) or beat position information of the music and the music playback start time. It may be acquired as beat information. Here, “beat position information” refers to information indicating the reproduction timing of each beat position from the beginning of the music.

  In the above terminal device, the beat information acquisition unit acquires beat information indicating each beat position from the outside in accordance with the beat timing of the music.

  According to the configuration of the present invention, since beat information is acquired for each beat timing of a music piece, the beat position of the music piece can be accurately specified even for a music piece whose tempo changes midway. In addition, since there is no possibility of detecting ambient noise as compared with the case where the playback position of the music is collected by a microphone or the like and the beat position is specified, it is possible to perform a more reliable operation determination.

  In the above terminal device, the motion detection unit detects a user's motion with an acceleration sensor built in the device itself, and the motion determination unit includes a beat position based on beat information and an amplitude peak position based on detection data of the acceleration sensor. In accordance with the comparison result on the same time axis, it is determined whether or not the user moves his body according to the music.

  According to the configuration of the present invention, the beat position of the music and the amplitude peak position (peak position of the amplitude value) based on the detection data of the acceleration sensor are compared on the same time axis so that the user can adjust the body to the beat. It is possible to accurately determine whether or not he is moving (whether or not he is dancing). For example, even if the beat position interval matches the peak position interval (the phase is the same), if the positional relationship on the time axis between the beat position and the peak position is far away, it is determined that the song is not dancing, It is possible to prevent erroneous determinations such as when walking at the same speed as the speed of. In addition, since the acceleration sensor is generally built in a general-purpose terminal device such as a smartphone or a mobile phone, the present invention can be applied without cost.

  A communication system of the present invention is a communication system including one or more terminal devices described above and an information processing device capable of communicating with the one or more terminal devices, and the terminal device displays the determination result of the operation determination unit. The information processing device further includes a determination result transmission unit that transmits the information to the information processing device, the information processing device totaling the determination results transmitted from the one or more terminal devices, and a totaling result output unit that outputs the totaling result of the totaling unit. , Provided.

According to the configuration of the present invention, by the information processing device, the operation determination result by the terminal device is totaled, and the totaled result is output, so that how many people are dancing in the floor such as a club or a music bar, That is, it can be used as a material for judging how many people like the music they have played.
In addition, it is possible that the “total result output unit” outputs the total result by display, voice, communication, or the like.

  In the above communication system, when the motion determination unit determines that the user is moving the body according to the music, the motion determination unit further determines the sharpness of the motion, and the determination result is that the user moves the body according to the music. It is an action index value that varies depending on whether or not the action is sharp.

According to the configuration of the present invention, (1). (2) obtaining an action index value according to whether or not the person is dancing; The user's favorite degree can be determined by any method of obtaining the motion index value in consideration of not only whether or not the person is dancing but also the sharpness of movement. In the latter case, it can be determined that the favorite degree of the music is high when the movement is good, for example, and the favorite degree of the music is low when the movement is bad.
In the case of (1) above, it is determined whether or not the dance is performed in units of music, and the motion index value may be expressed as a binary value (“0” or “1”), or for a predetermined time (beat unit, measure). It is also possible to detect whether or not each unit is dancing, and to represent the motion index value by the total value or average value of the binary values.

  In the above communication system, the tabulation unit sums up the motion index values transmitted from each terminal device for each music piece.

  According to the configuration of the present invention, it is possible to determine the popularity of music.

  In the communication system, the information processing apparatus further includes a terminal device detection unit that detects a terminal device that is present in the communication range and can be determined by the operation determination unit, and the counting unit transmits the operation transmitted from each terminal device. A climax index is calculated by dividing the sum of the index values by the number of terminal devices detected by the terminal device detection unit.

  According to the configuration of the present invention, the degree of excitement in the floor can be determined by dividing the total of the operation index values by the number of terminal devices. That is, it is possible to determine the degree of excitement without being influenced by the number of people on the floor, on the assumption that the expression “favorite degree (motion index value) average value is high = excited” is established.

  In the communication system, the information processing apparatus further includes a storage unit that stores a climax index calculated for each song for a predetermined period, and the totaling unit is a sum of the climax indices for each song stored within a predetermined period, or a predetermined index. The ranking for each music piece is calculated based on the average value of the excitement index for each music piece stored within the period.

  According to the configuration of the present invention, it is possible to determine the ranking for each piece of music within a predetermined period (one day, one week, one month, etc.). In other words, on the assumption that the formula of “the sum of the swell index is high (the number of performances is high) or the average value of the swell index is high = the popularity of the song is high” is established, Judgment can be made.

  A program according to the present invention causes a computer to execute each step in the determination result recording method of the terminal device.

  By using this program, it is possible to realize a determination result recording method for a terminal device that can record a user's favorite music piece without performing complicated operations.

  The in-store server 3 receives an operation index value indicating a customer operation determination result from each terminal device 5, and performs aggregation. Further, the totaling result is output to the music reproducing device 1. Further, the in-store server 3 acquires beat information and music playback information from the music playback device 1 and transmits them to each terminal device 5.

  The terminal device 5 is a smartphone, for example, and displays a music log display screen D1 (see FIG. 7) based on the music playback information transferred from the in-store server 3. Further, the user's movement is detected by the built-in acceleration sensor 54 (see FIG. 2B), and it is determined whether or not the user is dancing. Further, the determination result is recorded as a bookmark 62 on the music log display screen D1, and an operation index value indicating the determination result is transmitted to the in-store server 3. In addition, as the terminal device 5, you may apply various tablet terminals other than a smart phone, a mobile phone, a small personal computer, etc.

  Next, the hardware configuration of the in-store server 3 and the terminal device 5 will be described with reference to FIG. FIG. 2A is a block diagram of the in-store server 3. The in-store server 3 includes a control mechanism 31, a router side interface (hereinafter referred to as “router side I / F”) 32, a hub side interface (hereinafter referred to as “hub side I / F”) 33, a memory 34, A display 35 and operation keys 36 are provided.

  The control mechanism 31 is configured by a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like, and comprehensively controls each unit in the in-store server 3. Also, the router side I / F 32 inputs and outputs information with each terminal device 5 via the wireless LAN router 4. The hub side I / F 33 inputs and outputs information to and from the music playback device 1 via the LAN hub 2. The memory 34 stores various control programs and various data in a nonvolatile manner. In the present embodiment, it is also used for storing the total result of operation index values received from each terminal device 5. In addition, the display 35 displays various information such as a total result display. The operation keys 36 are used for various operations such as setting of total items.

  FIG. 2B is a block diagram of the terminal device 5. The terminal device 5 includes a control mechanism 51, a wireless communication interface (hereinafter referred to as “wireless communication I / F”) 52, a memory 53, an acceleration sensor 54, and a touch panel 55.

  The control mechanism 51 is configured by a CPU, a RAM, and the like, and comprehensively controls each unit in the terminal device 5. The wireless communication I / F 52 inputs and outputs information with the in-store server 3 via the wireless LAN router 4. The memory 53 stores various control programs and various data in a nonvolatile manner. In the present embodiment, the terminal device 5 is also used for storage of an operation determination application for performing operation determination (determination of whether or not dancing), music log display, bookmark recording, and the like. The operation determination application is downloaded from an application server (not shown).

  Further, the acceleration sensor 54 detects a change in acceleration at a predetermined sampling period, and is used for user's motion determination in this embodiment. The user uses the terminal device 5 by storing the terminal device 5 in a pocket or bag of clothes, holding it in a hand, or wearing it on a wrist or the like when performing an operation determination. As the acceleration sensor 54, a gravity acceleration sensor or the like is used, and the number of axes such as one axis, two axes, and three axes is not limited. When the multi-axis acceleration sensor 54 is used, the user's action is determined from the result of integrating the amplitude values in the detection data of each axis. Further, by using a plurality of acceleration sensors 54 or using in combination with a gyro sensor, an angular velocity sensor, a geomagnetic sensor, or the like, the user's operation may be determined more accurately.

  The touch panel 55 displays various information such as a music log display screen D1 (see FIG. 7) and an environment setting screen for an operation determination application. The music log display screen D1 displays a bookmark 62 indicating whether or not the user has danced to each music on the music playback list based on the music playback information.

  Next, the functional configuration of the music playback system SY (music playback device 1, in-store server 3 and terminal device 5) will be described with reference to FIG. The music reproducing device 1 includes a reproducing unit 110 and a display unit 120 as main functional configurations. The reproduction unit 110 reproduces music by the respective DJ players 11 and 13 and outputs music reproduction information to the in-store server 3 at a predetermined timing such as when reproduction of music is started. In addition, the music playback device 1 sends beat information according to the beat timing of the music.

  As shown in FIG. 4, a packet is transmitted in real time from the wireless LAN router 4 in accordance with the beat timing of the music played (flowed to the floor) by the music playback device 1. In this case, the position (time) of each packet indicates the beat position, and the length between adjacent packets on the time axis indicates the beat interval. The beat information uses beat information necessary for beat synchronization processing between the players 11 and 13 (processing for matching beats of two or more pieces of music to be mixed). That is, the terminal device 5 of this embodiment acquires beat information using the synchronization processing function originally installed in the music playback device 1.

  The display unit 120 displays various tabulation results tabulated by the in-store server 3 in a predetermined display area provided in each DJ player 11, 13. As the total result, total items such as “total of operation index values”, “swelling index” and “ranking by music” are displayed (see FIGS. 5B to 5D). As a result, it is possible to provide the DJ with information on how much the floor is currently exciting and what kind of music is popular in the store where the performance is being performed.

  The in-store server 3 includes a beat information transmission unit 310, a terminal device detection unit 320, a totaling unit 330, a storage unit 340, a totaling result output unit 350, and a display unit 360 as main functional configurations.

  The beat information transmission unit 310 transmits the beat information transmitted along with the reproduction of the music reproduction device 1 (reproduction unit 110) by the router side I / F 32 to each terminal device 5 capable of communication. The terminal device detection unit 320 detects each terminal device 5 that is in a communication range and has an operation determination application activated. Note that the “each communicable terminal device 5” in the present embodiment refers to the terminal device 5 that is in the communication range and in which the operation determination application is activated.

  The totaling unit 330 totals the operation determination results (operation index values) transmitted from the communicable terminal devices 5 by the control mechanism 31. Here, the details of the counting unit 330 will be described with reference to FIG. FIG. 5A shows information acquired by the counting unit 330, that is, “operation index value”. The “motion index value” is information indicating whether or not the user who owns each terminal device 5 is dancing. Also, assuming that the diagram “Dancing to a song = I like the song” holds, the “motion index value” indicates the favorite degree of each user. In the present embodiment, whether or not the dance is performed for each music piece is represented by a binary value (“0” or “1”).

  5B to 5D show the totaling items of the totaling unit 330. As shown in FIG. 5B, the “total of operation index values” indicates the total of operation index values acquired from each terminal device 5 that can communicate, that is, the number of people dancing on the floor.

  Further, as shown in FIG. 5C, the “rising index” is obtained by dividing the “total of operation index values” by the number of terminal devices 5 in which the operation determination application is activated (= communication is possible). It is a value that shows the percentage of people dancing on the floor. In addition, assuming that the expression “favorite degree (motion index value) average value is high = excited” is established, the “exciting index” indicates the degree of excitement in the floor.

  Further, as shown in FIG. 5D, the “music ranking A” indicates a ranking based on the sum of the climax indices for one week (predetermined period), for example. In other words, if it is assumed that the formula “the sum of the climax is high (the number of performances is high) = the popularity of the music is high” is established, “Ranking by song A” indicates the popularity of the music in the week. . Note that the total of the “swelling index” for each song within one week and the number of performances of each song are stored in the storage unit 340 (memory 34). The “music ranking B” indicates a ranking based on the average value of the climax index for one week (predetermined period), for example. The “average value of the climax index” is obtained by dividing the sum of the climax indices during a predetermined period by the number of performances. In other words, if it is assumed that the expression “average value of the climax index is high = music popularity is high” is established, “music ranking B” also indicates the popularity of music in the week.

  In addition, which of the above-mentioned aggregation items (“total of operation index values”, “rising index”, “ranking A by song”, “ranking B by song”) is to be counted, and which is a song Whether to output to the playback device 1 may be selectable by operating the operation key 36 of the in-store server 3.

  The tabulation result output unit 350 displays the tabulation result of the tabulation unit 330 on the display unit 360 (display 35) of the in-store server 3 and transmits it to the music reproducing device 1 (display unit 120). Of the total results, the “total of operation index values” and the “rising index” are totaled in units of several seconds to several minutes, and the total result is output each time. The “ranking by song” is counted when the DJ performs a ranking display operation on the music playback device 1 or when the server administrator performs a ranking display operation on the in-store server 3, and is counted each time. Output the result. The “ranking by song” may also be configured to periodically count without depending on the operation of the DJ or server administrator. In addition, a configuration may be used in which each tabulation item is tabulated at a predetermined timing (at the start / end of playback of music, when a DJ is changed, etc.).

  The terminal device 5 includes a beat information acquisition unit 510, an operation detection unit 520, an operation determination unit 530, a recording unit 540, and a determination result transmission unit 550 as main functional configurations.

  The beat information acquisition unit 510 acquires beat information transferred from the in-store server 3 (beat information transmission unit 310) through the wireless communication I / F 52. The motion detection unit 520 detects the motion of the user holding the terminal device 5 by the acceleration sensor 54.

  The motion determination unit 530 determines whether or not the user moves his body according to the music according to the comparison result between the beat information acquired by the beat information acquisition unit 510 and the detection value by the motion detection unit 520. Here, the principle of operation determination will be described. FIG. 6A is a graph showing a comparison result between beat information when the user is dancing and detection data of the acceleration sensor 54 (hereinafter referred to as “acceleration sensor data”). The horizontal axis in the figure represents time, and the vertical axis represents the amplitude of the user's movement (the amplitude value of the acceleration sensor data). A thin dotted line on the graph indicates acceleration sensor data (amplitude waveform) based on the user's movement, and a thick straight line indicates beat information (beat position) based on the beat of the music.

  As shown in the figure, control is performed when the positional relationship with time of the peak position (peak time t1) of the acceleration sensor data and the beat position (beat time t2) is close (when the synchronization ratio between the peak position and the beat position is high). The mechanism 51 determines that the user is moving (dancing) in time with the beat. Further, as shown in FIG. 6B, when the positional relationship between the peak position (peak time t1) and the beat position (beat time t2) of the acceleration sensor data is distant, the control mechanism 51 performs the beat. Also, determine that you are not moving (doing not dance). In the present embodiment, the beat interval and the interval between adjacent peak positions on the time axis (hereinafter referred to as “peak interval”) are the same or have a predetermined relationship (the phase of beat information and acceleration sensor data). Or even if the relationship between the peak position (peak time t1) and the beat position (beat time t2) is distant, Determine that you are not dancing. As a result, when the user happens to walk at the same speed as the music, the operation is not erroneously determined as “dancing”.

  The recording unit 540 records the identification information indicating the determination result of the operation determination unit 530 in association with the information indicating the music by the control mechanism 51. FIG. 7 shows a display example of the music log display screen D1 when the bookmark 62 is recorded as the identification information. The music log display screen D1 includes a currently reproduced music display area E1 and a past reproduced music display area E2. In the currently reproduced music display area E1, the cover art 61, title, artist, DJ name, etc. of the music album are displayed for the currently reproduced music. In addition, when the motion determination unit 530 determines “dancing” during the reproduction of the music, the bookmark 62 recorded by the recording unit 540 is displayed. On the other hand, the past reproduction music display area E2 displays the music album cover art 61, title, artist, DJ name, date (reproduction date and time), etc., for each music reproduced in the past. In addition, a bookmark 62 is displayed for a song that is determined to be “dancing” by the motion determination unit 530 during playback of each song.

  Although not particularly illustrated, the user performs a selection operation of the bookmark 62 displayed in the currently played music display area E1 and the past played music display area E2, so that the music purchase page for the corresponding music on the music sales website is displayed. , And detailed music information (album name, release date, music recommendation, etc.) can be displayed as a pop-up screen from the music information site.

  Note that the bookmark 62 may not be recorded on the music log display screen D1, but a flag indicating dancing may be stored in the music reproduction log in association with the music log display screen D1. In this case, when the music reproduction log is read by another device (home PC) or the like, it is displayed so as to be identifiable as to whether or not it is a favorite music.

  The determination result transmission unit 550 transmits the determination result (operation index value) of the operation determination unit 530 to the in-store server 3 (aggregation unit 330) through the wireless communication I / F 52. In the present embodiment, the determination result transmission unit 550 transmits the determination result (motion index value = “1”) when the motion determination unit 530 determines “dancing”.

  Next, the operation determination process of the terminal device 5 will be described with reference to the flowchart of FIG. As shown in the figure, the motion determination process includes an acceleration sensor data processing thread, a beat information processing thread, an evaluation thread, and a determination result processing thread.

  First, the acceleration sensor data processing thread will be described. The terminal device 5 (control mechanism 51) acquires acceleration sensor data, which is a detection result of the acceleration sensor 54 (S01), and buffers the acceleration sensor data for a certain time (S02). Subsequently, noise is removed by performing a filtering process on the acceleration sensor data for a certain time using a low-pass filter (S03). Further, the peak position (peak time t1) and peak interval (frequency) of the acceleration sensor data from which noise has been removed are detected (S04), and the phase shifted by the time required for buffering and the filtering process is corrected (peak). The time t1 is corrected, S05). In addition, after S05, it becomes an infinite loop and returns to S01.

  On the other hand, in the beat information processing thread, when beat information is acquired via the wireless LAN router 4 (S11), the acquisition time is acquired as a beat position (beat time t2) (S12), and beat information indicating the beat position is acquired. Buffering is performed for a certain time (S13). In addition, after S13, it becomes an infinite loop and returns to S11.

  Subsequently, in the evaluation thread, an integrated value of a difference between the peak position obtained by the acceleration sensor data processing thread (peak time t1) and the beat position obtained by the beat information processing thread (beat time t2) within a certain time is calculated. Then, it is determined whether or not the integrated value is equal to or less than a predetermined value (S21). And when an integrated value is below a predetermined value (S21: Yes), it determines with a user dancing (S22). When the integrated value exceeds the predetermined value (S21: No), it is determined that the user is not dancing (for example, the user is stationary or walking) (S23).

  Although not shown in particular, the determination as to whether or not the dance is performed by the evaluation thread is a determination for a user's movement for a certain period of time. Therefore, the determination of whether or not the dance is performed according to the music is performed by repeating the evaluation thread a plurality of times during the music reproduction. For example, when it is determined that a song is “dancing” more than a predetermined number of times by the evaluation thread, or the number of times determined to be “dancing” is greater than the number of times determined to be “not dancing” In many cases, a determination method such as determining “dance” according to the music may be considered.

  Subsequently, in the determination result processing thread, the evaluation (determination result) by the evaluation thread is recorded as the bookmark 62 on the music log display screen D1 (see S24, FIG. 7). Further, the operation index value as the determination result is transmitted to the in-store server 3 (S25).

  As described above, according to the present embodiment, the determination result as to whether or not the user is dancing is recorded as the bookmark 62, so that favorite music can be recorded without requiring a complicated operation. it can. In addition, the in-store server 3 totals the operation determination results by the terminal devices 5 and outputs the total results, so that how many people are dancing in the floor of a club, a music bar or the like, that is, the music played Can be used as a basis for judging how many people like the item. In addition, since the “swell index” is calculated by dividing the total of the operation index values by the number of terminal devices as the totaling result, it is possible to determine an objective swell level without being influenced by the number of people on the floor. . Moreover, since the “ranking by song” within a predetermined period is calculated as the total result, the popularity by song in the predetermined period can be determined.

  Further, since the user's motion is detected using the acceleration sensor 54 built in the terminal device 5, it is possible to easily perform motion determination even in an environment where the user can freely change the place where the user dances. Further, since the acceleration sensor 54 is generally built in the general-purpose terminal device 5, the operation determination process can be executed without cost. Further, by comparing the beat position of the music and the peak position of the amplitude value based on the detection data of the acceleration sensor 54 on the same time axis, it can be accurately determined whether or not the user is dancing.

  In addition, since beat information indicating each beat position is acquired for each beat timing of the music, even the music whose tempo changes midway, the beat position of the music can be accurately determined. In addition, compared to the case where the playback position of a music piece is collected by a microphone or the like and the beat position is detected, saturation by collecting in a loud volume environment such as a club, or detection of noise caused by intense user movement, etc. Since there is no worry, a more reliable determination can be made.

  Further, in the evaluation thread, it is possible to determine whether or not the user is dancing by simply determining whether or not the integrated value of the difference between the beat position and the peak position within a predetermined time is equal to or less than a predetermined value, so that the control load is small. Furthermore, since the acceleration sensor data processing thread corrects the time lag required for buffering and filtering processing of the acceleration sensor data, the operation determination can be performed more accurately.

[Modification 1]
In the embodiment described above, it is determined whether or not the user is dancing in the evaluation thread. However, it is also possible to determine how to dance. Hereinafter, a modified example of the dance evaluation method will be described with reference to FIGS. 9 and 10. FIGS. 9A to 9C show three types of acceleration sensor data (thin dotted lines) based on different user movements. Note that the beat information (thick straight lines) shown in FIGS. 9A to 9C are the same and indicate that they are synchronized with the acceleration sensor data. Thus, it is preferable to perform the evaluation of how to dance only when it is determined that the user is dancing (after S22).

  For example, as shown in FIG. 9A, when the amplitude of the peak position of the acceleration sensor data is small (for example, when the integrated value or average value of the amplitude of the peak position within a certain time is equal to or less than a predetermined value, or constant The control mechanism 51 evaluates that the user is dancing gently when the amplitude of the peak position exceeds the predetermined value within the time is less than the predetermined number). Conversely, as shown in FIG. 9B, when the amplitude of the peak position of the acceleration sensor data is large (for example, when the integrated value of the amplitude of the peak position within a certain time exceeds a predetermined value, or within a certain time) When the number of times that the amplitude of the peak position exceeds a predetermined value exceeds the predetermined number), the control mechanism 51 evaluates that the user is dancing violently.

  Furthermore, as shown in FIG. 9C, when the rising and / or falling of the convex waveform indicating the peak position of the acceleration sensor data (detection waveform) becomes steep, the control mechanism 51 is sharp to the user. Evaluate that it is moving (having a sharp movement). Note that whether or not the user's movement is sharp can be more accurately evaluated by frequency analysis (FFT analysis) of the acceleration sensor data. FIG. 10 is a diagram illustrating a frequency analysis result (frequency distribution) of acceleration sensor data based on an actual experimental result.

  In FIG. 10, the horizontal axis indicates frequency [Hz], and the vertical axis indicates amplitude energy. Moreover, the same figure (a) shows the frequency analysis result when the user is dancing with a sharp movement, and the same figure (b) is the frequency analysis result when the user is dancing with a sharp movement. Show. As shown in FIG. 5A, when the dance is not sharp, the movement is smooth (close to a sine wave), so that only the basic period of the movement and the doubled period appear as peaks. On the other hand, as shown in FIG. 5B, when performing a sharp dance, the movement becomes sharp, and a peak appears up to about 5 times the basic period. In this way, it is possible to evaluate whether or not there is a sharpness, depending on how many times the peak appears with reference to the basic period. For example, when a peak appears up to a five-fold cycle of the basic period, it is a sharp operation, and when it is not a phase, it may be determined that there is no sharpness. Also, if the peak appears up to a double frequency, it is “level 1”. If it appears up to a triple frequency, it is “level 2”. If it appears up to a quadruple frequency, it is “level 3”.・ The level may be judged as such.

  In the present modification, the motion determination unit 530 may vary the motion index value according to how to dance (for example, whether the motion is intense or whether the user's motion is sharp). In other words, the motion index value is not simply represented by “0” or “1” depending on whether or not it is dancing, but for example, “1” when there is sharpness, “0.5” when there is no sharpness. When not dancing, the motion index value may be varied according to the presence or absence of sharpness, such as “0”. Further, as described above, the operation index value may be varied more finely according to the level of sharpness (how many times the peak appears). According to this configuration, it is possible to determine the user's favorite degree in consideration of not only whether or not the dance is performed but also how to dance.

  Further, the evaluation of the evaluation thread may be presented to the user by displaying the operation index value on the music log display screen D1. According to this configuration, it is possible to indicate to the user whether or not the dance is good, and it is possible to stimulate the user's improvement.

[Modification 2]
In the evaluation thread of the above embodiment, the user's motion determination is performed using the acceleration sensor 54, but other sensors may be used. For example, using the azimuth sensor, the direction in which the terminal device 5 faces is detected at 0 to 360 °, and when the detection data of the azimuth sensor changes periodically, it may be determined that the user is dancing.

  Further, in combination with the detection result of the acceleration sensor 54, when the detection data of the direction sensor changes periodically and the amplitude peak value of the acceleration sensor 54 exceeds a certain value in accordance with the cycle, the user dances It may be determined that Furthermore, the period may be compared with the period of the beat information, and if the period is multiplied or multiplied by an integer, it may be determined that the user is dancing. Furthermore, when it is determined that the evaluation thread shown in the first embodiment is dancing and it is determined that the evaluation thread according to the second modification is also dancing (when the and condition is satisfied), the user is dancing You may judge. In this way, by using the azimuth sensor, it is possible to clearly distinguish the motion when walking and the motion when dancing.

[Modification 3]
In the above embodiment, the beat information is acquired by acquiring a packet indicating the beat timing (see FIG. 4). However, the reproduction sound of the music is collected by the microphone, and the analysis result of the reproduction sound is acquired as the beat information. May be. According to this configuration, since a microphone generally incorporated in the general-purpose terminal device 5 can be used, beat information can be acquired without incurring costs.

  In addition, as the beat information, BPM (Beats Per Minute) or beat position information of the music may be acquired at the start of music playback. Further, the music playback start time and the BPM or beat position information may be acquired before the music playback starts.
