In addition, the terminal 200 receives the location information of the toothbrush transmitted from the toothbrush 100, the brushing time, identification information of the toothbrush 100, and the like.

In addition, in relation to the tooth brushing guide content being output from the terminal 200, the terminal 200 brushes teeth for a plurality of brushing areas in which the order of configuring the tooth brushing guide sound source included in the tooth brushing guide content is determined (or designated). The location information of the toothbrush transmitted from the toothbrush 100 for each area, brushing time, etc. are stored (or accumulated/mapped/interlocked).

That is, the terminal 200 transmits position information of a plurality of toothbrushes from the toothbrush 100 in relation to a specific brushing area among the plurality of brushing areas, a plurality of brushing times (or a cumulative brushing by accumulating a plurality of brushing times). time), etc. are mapped and stored.

In addition, the terminal 200 performs the stored (or accumulated / Based on the location information of a plurality of toothbrushes related to a specific brushing area (mapped/linked), it is primarily checked (or determined) whether the user who has the toothbrush 100 is brushing using the toothbrush 100 .

That is, the terminal 200 analyzes the location information of a plurality of toothbrushes related to the stored (or accumulated/mapped/interlocked) specific brushing area, and whether there is no change in the location information of the toothbrush (or quietly) whether there is a state), whether the amount of change in the position information of the toothbrush exceeds a preset threshold value (or a threshold range) (or whether the toothbrush is in a state of shaking the toothbrush at random), the change amount of the position information of the toothbrush is the threshold value It is checked whether it is a smaller state (or whether it is a state within a critical range), and the like.

As a result of the confirmation (or the determination result), when the user is not brushing teeth using the toothbrush 100 (or when there is no change in the position information of the toothbrush / when it is in a still state), or the toothbrush 100 When shaking (or moving) more than a preset threshold (or error range) (or when the amount of change in the position information of the toothbrush exceeds a preset threshold / When the change in the position information of the toothbrush is outside the preset threshold range / when the toothbrush is randomly shaken), the terminal 200 outputs guide information indicating that correct tooth brushing should be performed. At this time, the terminal 200 outputs a brushing guide sound source related to the next brushing area corresponding to the order following the specific brushing area among the plurality of brushing areas, and displays a brushing guide screen related to the next brushing area. Also, guide information indicating that the correct tooth brushing should be performed may be displayed on one side of a screen on which a brushing guide screen related to the next brushing area is displayed.

In addition, the terminal 200 sets a value corresponding to a state in which brushing is not performed at a preset normal brushing time based on the accumulated brushing time and the location information of a plurality of toothbrushes stored in relation to the specific brushing area (eg, 0). seconds) are summed (or accumulated). Here, the preset normal brushing time may be a value accumulated by the user normally brushing the brushing area corresponding to the brushing guide content.

In addition, whenever the output of the content for one brushing area in relation to the plurality of brushing areas included in the tooth brushing guide content being output from the terminal 200 is finished, the terminal 200 is expressed in the following [Equation 5] Accordingly, it calculates (or calculates) the degree of brushing achievement (or degree of achievement for each brushing area) related to the specific brushing area according to whether the user is brushing normally.

Herein, the normal brushing time is a normal brushing time accumulated for each individual brushing area among the plurality of brushing areas, and is accumulated from the first brushing area for the plurality of brushing areas in which the order is determined until the content output for the specific brushing area is finished. Normal brushing time, normal brushing time accumulated from the first brushing area for the plurality of brushing areas for which the order is determined to the brushing area before the brushing area corresponding to the currently output brushing guide content, and the plurality of brushing areas for which the order is determined It may be any one of normal brushing time accumulated from the first brushing area to the brushing area corresponding to the currently output brushing guide content. In addition, the total time for brushing is the total time for brushing for each individual brushing area among the plurality of brushing areas, and the total amount of brushing from the first brushing area to the end of content output for the specific brushing area for the plurality of brushing areas in which the order is determined. Time, total time for brushing from the first brushing area for the plurality of brushing areas for which the order is determined to the brushing area before the brushing area corresponding to the currently output brushing guide content, the first time for the plurality of brushing areas for which the order is determined It may be any one of total brushing time accumulated from the brushing area to the brushing area corresponding to the currently output brushing guide content.

In addition, the terminal 200 displays the calculated degree of achievement of brushing on the other side of the screen on which the brushing guide content is displayed. Here, the terminal 200 calculates the overall brushing achievement for at least one brushing area in which brushing has been performed so far, in addition to the brushing achievement for each brushing area, and uses the calculated overall brushing achievement on the screen on which the brushing guide content is displayed. It can also be displayed on the other side.

In this case, in order to calculate the degree of achievement of brushing for each brushing area, the terminal 200 does not manage (or accumulate) the normal brushing time, which is the time the user normally brushes teeth, but instead of managing (or accumulating) the plurality of brushing areas in advance. A value (for example, 0) corresponding to a state of not brushing teeth may be accumulated (or summed) in the set flag.

In addition, the terminal 200 calculates the brushing achievement according to the flag according to the following [Equation 6].

In addition, the terminal 200 displays the degree of brushing achievement according to the calculated corresponding flag on the other side of the screen on which the brushing guide content is displayed.

Here, the flag is a value that is accumulated according to whether a user is normally brushing teeth with respect to the plurality of preset brushing areas, and the number of accumulated brushing areas is a value that is currently being output among the plurality of preset brushing areas. The number of brushing areas accumulated in response to the guide content (or the number of accumulated brushing areas from the first brushing area of the tooth brushing guide content to the brushing area one step before the brushing area of the currently output brushing guide content) have.

For example, when brushing guide content including a song and an image related to the 7th brushing area is currently being output according to the output of the brushing guide content from among 13 brushing areas, the terminal 200 determines which information the user selects until the 6th brushing area. In order to provide whether or not you have properly brushed your teeth, check the accumulated flags up to the 6th brushing area (eg 5) and the number of accumulated brushing areas up to the 6th brushing area (eg 6) .

In addition, the terminal 200 divides the accumulated flag (eg, 5) by the number (eg, 6) of the accumulated brushing areas up to the identified 6th brushing area and multiplies it by a preset value of 100, 6 Calculate the real-time brushing achievement up to the 6th brushing area (eg 5/6*100 = 83.3%), and calculate the real-time brushing achievement up to the 6th brushing area (eg 83.3%) in the 7th brushing area It is displayed on the other side of the screen on which the related brushing guide content is displayed.

In an embodiment of the present invention, whenever brushing for one brushing area is finished according to the toothbrush location information and brushing time transmitted in real time from the toothbrush 100, the degree of brushing achievement is calculated according to whether the user is brushing normally. and display, but is not limited thereto, and the terminal 200 provides real-time brushing according to whether the user is normally brushing teeth according to the toothbrush location information and brushing time transmitted in real time from the toothbrush 100 . The degree of achievement may be calculated, and the calculated degree of achievement of brushing may be displayed on the other side of the screen on which the brushing guide content is displayed.

For example, when brushing guide content including a song and an image related to the 7th brushing area is currently being output according to the output of the brushing guide content among 13 brushing areas, the terminal 200 may In order to provide information on whether or not the user has properly brushed teeth, location information and brushing time of the toothbrush 100 provided in real time from the toothbrush 100 are reflected (or applied) to reflect (or apply) the current brushing guide content. The accumulated flags up to the 7th brushing area (eg, 5) and the number of accumulated brushing areas up to the 7th brushing area (eg, 7) are checked.

In addition, the terminal 200 divides the accumulated flag (eg, 5) by the number (eg, 7) of the accumulated brushing areas up to the identified 7th brushing area and multiplies it by a preset value of 100, 7 Calculate the real-time brushing achievement up to the 7th brushing area (eg 5/7*100 = 71.4%), and calculate the real-time brushing achievement up to the 7th brushing area (eg 71.4%) in the 7th brushing area It is displayed on the other side of the screen on which the related brushing guide content is displayed.

As such, the calculated brushing achievement is a value calculated in consideration of the brushing area corresponding to the currently output brushing guide content (or the brushing area currently being brushed), or the brushing area corresponding to the currently output brushing guide content ( Alternatively, the current brushing area) may be a calculated value in consideration of the previous brushing area.

In addition, as a result of the confirmation (or the determination result), when the user is brushing teeth using the toothbrush 100 (or when the amount of change of the location information of the toothbrush is smaller than the threshold value / The amount of change of the location information of the toothbrush If it exists within the threshold range), the terminal 200 determines the user based on the stored (or accumulated) location information of a plurality of toothbrushes related to the specific brushing area and a specific brushing area corresponding to the corresponding brushing guide content. Determines (or confirms) whether a specific brushing area has been brushed.

That is, as a result of the confirmation (or the determination result), when the user is brushing teeth using the toothbrush 100 , the terminal 200 displays the brushing currently being output through the terminal 200 among the plurality of preset brushing areas. The specific brushing area that is the previous brushing area than the brushing area corresponding to the guide content is identified.

In addition, in order to determine whether the user has normally brushed the specific brushing area with respect to the identified specific brushing area, the terminal 200 may be within a preset toothbrush angle range with respect to the identified specific brushing area. It is determined whether the location information of the plurality of toothbrushes stored in relation to the specific brushing area is included.

At this time, the terminal 200 determines the amount of change in the position information of the toothbrush according to the position information of the plurality of toothbrushes stored in relation to the specific brushing area and the amount of change in reference according to the brushing method preset (or stored) in relation to the specific brushing area. Based on the , it may be determined whether the user has normally brushed a specific brushing area. Here, the brushing method preset in relation to the specific brushing area may be a brushing method related to song lyrics stored in advance in response to the specific brushing area (for example, including round, squash, etc.).

That is, the terminal 200 determines that the change amount of the position information of the toothbrush according to the position information of the plurality of toothbrushes related to the specific brushing area is identical to (or the same as) the standard change amount corresponding to the brushing method according to the song lyrics of the specific brushing area. / It is determined whether it exists within the preset error range).

In this way, the terminal 200 determines whether the position information of the plurality of toothbrushes is included within the preset toothbrush angle range for the specific brushing area, and the amount of change in the location information of the plurality of toothbrushes is the specific brushing area. It is possible to determine whether the user has normally brushed the specific brushing area by determining whether the area coincides with a preset reference change amount (or exists within an error range), and the like.

As a result of the determination (or the confirmation result), when it is determined that the user is not in a state of brushing a specific brushing area, the terminal 200 provides a guide indicating that the user has brushed a different area (or other brushing area) than the instruction print information At this time, the terminal 200 outputs a brushing guide sound source related to the next brushing area corresponding to the next order of the specific brushing area among the plurality of brushing areas, and displays a brushing guide screen related to the next brushing area. In addition, guide information indicating that the toothbrushing guide screen related to the next brushing area is displayed may be displayed on one side of the screen indicating that the area different from the instruction is brushed. Here, the guide information indicating that the area different from the instruction is brushed includes voice information on the correct position, text information on the correct position, and a preset color (for example, It includes information such as displaying a red or hatched line to indicate that you are not brushing at the correct brushing position.

Hereinafter, the toothbrushing training method according to the present invention will be described in detail with reference to FIGS. 1 to 7 .

3 is a flowchart illustrating a toothbrushing training method according to an embodiment of the present invention.

First, when a preset event occurs, the toothbrush 100 performs a short-range communication connection function (or communication function/connection function) between the toothbrush 100, which is a preset function in response to the event, and the terminal 200 located in a short distance. carry out At this time, the event is when a touch (or click/selection) on a button (eg, power button/menu) provided on one side of the toothbrush 100 is sensed, the touch on the button is preset time (eg, For example, if it is maintained for more than 2 seconds), when an inclination of more than a preset threshold value in the up/down/left/right direction of the toothbrush 100 is detected, the inclination state of the toothbrush 100 or more of the threshold value is the When it is maintained for more than a preset time, when movement (or shaking/vibration) of the toothbrush 100 in the up/down (or up/down) direction, left/right direction, or diagonal direction more than a certain number of times is detected, the Including cases in which rotation (or movement) of the toothbrush 100 in the clockwise/counterclockwise direction is sensed more than a certain number of times. Here, the short-range communication connection may include Bluetooth, RFID, infrared communication (IrDA), UWB, Zigbee, adjacent magnetic field communication (NFC), ultrasonic communication (USC), visible light communication (VLC), Wi-Fi, Wi-Fi Direct, etc. have.

For example, when the power button provided on one side of the first toothbrush 100 is touched, the first toothbrush searches for one or more terminals located around the first toothbrush using a preset Bluetooth communication method.

In addition, when the second terminal 200 is searched for by the search process, the first toothbrush performs a pairing process with the found second terminal, and then establishes a Bluetooth method between the first toothbrush and the second terminal. connected through (S310).

Thereafter, the terminal 200 outputs a preset brushing guide content when a preset time (for example, 3 seconds) elapses after being connected to the toothbrush 100 in communication. Here, the tooth brushing guide content includes a tooth brushing guide sound source, a tooth brushing guide screen corresponding to the tooth brushing guide sound source, and the like. In addition, the brushing guide sound source includes a song including a brushing method for brushing (or brushing) for each brushing area for a plurality of preset brushing areas, a narration corresponding to explanatory information for brushing for the plurality of brushing areas, etc. includes In addition, the brushing guide screen includes information (or screen/data) including a tooth image, a specific brushing area according to the tooth brushing guide sound source, song lyrics included in the tooth brushing guide sound source, for the plurality of preset brushing areas, It is composed (or included) with information (or screen/data) including narration, etc. At this time, the plurality of tooth brushing areas (or tooth areas) is a left molar outer surface (or left molar outer surface), an incisor outer surface, a right molar outer surface (or right molar outer surface), lower left chewing surface (or lower left molar teeth) chewing surface), lower right chewing surface (or mandibular right molar chewing surface), right molar chewing surface (or maxillary right molar chewing surface), left molar chewing surface (or maxillary left molar chewing surface), lower left molar inner surface (or Lower left molar inner surface), lower inner surface of lower incisor (or inner surface of lower incisor), inner surface of lower right molar (or inner surface of lower right molar), inner surface of upper right molar (or inner surface of right roof of mouth / inner surface of upper right molar) ), upper medial surface of upper incisors (or medial surface of upper incisors/medial surface of maxillary incisors), medial surface of upper left molars (or medial surface of left roof of mouth/medial surface of maxillary left molars).

For example, when a preset 3 seconds have elapsed after a wireless connection between the first toothbrush and the second terminal in a Bluetooth manner, the second terminal outputs the Lala Chika song, which is the brushing guide content stored in advance in the second terminal. In this case, the Lala Chika Song includes a first brushing guide sound source composed of a song including a brushing method for each brushing area for 13 brushing areas preset by the user, and a narration including a description of additional actions in the brushing process; Information for each brushing area according to the output of the first brushing guide sound source, text (eg, including song lyrics, narration, etc.) included in the first brushing guide sound source, and a first brushing guide screen composed of a first tooth image .

In addition, as shown in FIG. 4 , the second terminal displays the first brushing guide screen 400 included in the Lala Chikasong ( S320 ).

Then, when the user holding the toothbrush 100 brushes teeth using the toothbrush 100 while checking (or watching/listening) the brushing guide content output to the terminal 200, the toothbrush 100 ) operates according to the electric toothbrush function, and measures (or collects) location information of the toothbrush according to the user's brushing using the toothbrush 100, brushing time, etc.

In addition, the toothbrush 100 transmits the measured (or collected) position information of the toothbrush, brushing time, identification information of the toothbrush 100, and the like to the terminal 200 . Here, the identification information of the toothbrush 100 includes preset unique information (or unique number/unique code), serial number, and the like.

For example, when the first user holding the first toothbrush brushes teeth according to the Lala Chikasong output from the second terminal, the first toothbrush sets the first toothbrush while the first user of the first toothbrush is brushing teeth. The location information of the first toothbrush in relation to the area, the first brushing time corresponding to the location information of the first toothbrush, and the like are measured.

In addition, the first toothbrush transmits the measured location information of the first toothbrush, the first brushing time, identification information of the first toothbrush, etc. to the second terminal (S330).

Thereafter, the terminal 200 receives the position information of the toothbrush, the brushing time, and identification information of the toothbrush 100 transmitted from the toothbrush 100 .

In addition, in relation to the tooth brushing guide content being output from the terminal 200, the terminal 200 brushes teeth for a plurality of brushing areas in which the order of configuring the tooth brushing guide sound source included in the tooth brushing guide content is determined (or designated). The location information of the toothbrush transmitted from the toothbrush 100 for each area, brushing time, etc. are stored (or accumulated/mapped/interlocked).

That is, the terminal 200 transmits position information of a plurality of toothbrushes from the toothbrush 100 in relation to a specific brushing area among the plurality of brushing areas, a plurality of brushing times (or a cumulative brushing by accumulating a plurality of brushing times). time), etc. are mapped and stored.

For example, the second terminal transmits the location information of the first toothbrush in relation to the first brushing area in which the first user is brushing, transmitted from the first toothbrush, the first brushing time, identification information of the first toothbrush, etc. receive

In addition, the second terminal in relation to the first brushing area (eg, the outer surface of the left molar) in the first brushing guide sound source in the Lala Chikasong output from the second terminal, at an interval of 1 msec from the first toothbrush The transmitted location information of the first toothbrush to the location information of the 5000th toothbrush, the first accumulated brushing time (for example, 5 seconds) related to the first brushing area, etc. are mapped and stored (managed) with the corresponding first brushing area (S340).

Thereafter, the terminal 200 performs the stored (or accumulated / Based on the location information of a plurality of toothbrushes related to a specific brushing area (mapped/linked), it is primarily checked (or determined) whether the user who has the toothbrush 100 is brushing using the toothbrush 100 .

That is, the terminal 200 analyzes the location information of a plurality of toothbrushes related to the stored (or accumulated/mapped/interlocked) specific brushing area, and whether there is no change in the location information of the toothbrush (or quietly) whether there is a state), whether the amount of change in the position information of the toothbrush exceeds a preset threshold value (or a threshold range) (or whether the toothbrush is in a state of shaking the toothbrush at random), the change amount of the position information of the toothbrush is the threshold value It is checked whether it is a smaller state (or whether it is a state within a critical range), and the like.

For example, the output of the first brushing area (for example, the outer surface of the left molar) in the first brushing guide sound source in the Lala Chikasong output from the second terminal is terminated, and the second brushing area ( When the first brushing guide sound source for (for example, the outer surface of the front teeth) is output, the second terminal maps the first brushing area and stores the amount of change between the location information of the first toothbrush and the location information of the 5000th toothbrush. By analyzing, it is checked whether the first user is in a still state, whether the first user is in a state of arbitrarily shaking the toothbrush, or whether the first user is normally brushing teeth (S350).

As a result of the confirmation (or the determination result), when the user is not brushing teeth using the toothbrush 100 (or when there is no change in the position information of the toothbrush / when it is in a still state), or the toothbrush 100 When shaking (or moving) more than a preset threshold (or error range) (or when the amount of change in the position information of the toothbrush exceeds a preset threshold / When the change in the position information of the toothbrush is outside the preset threshold range / when the toothbrush is randomly shaken), the terminal 200 outputs guide information indicating that correct tooth brushing should be performed. At this time, the terminal 200 outputs a brushing guide sound source related to the next brushing area corresponding to the next order of the specific brushing area among the plurality of brushing areas, and displays a brushing guide screen related to the next brushing area. Also, guide information indicating that the correct tooth brushing should be performed may be displayed on one side of a screen on which a brushing guide screen related to the next brushing area is displayed.

In addition, the terminal 200 sets a value corresponding to a state in which brushing is not performed at a preset normal brushing time based on the accumulated brushing time and the location information of a plurality of toothbrushes stored in relation to the specific brushing area (eg, 0). seconds) are summed (or accumulated). Here, the preset normal brushing time may be a value accumulated by the user normally brushing the brushing area corresponding to the brushing guide content.

In addition, whenever the output of the content for one brushing area in relation to the plurality of brushing areas included in the brushing guide content being output from the terminal 200 is finished, the terminal 200 according to the above [Equation 5] It calculates (or calculates) the degree of brushing achievement (or degree of achievement for each brushing area) related to the specific brushing area according to whether the user is brushing normally.

In addition, the terminal 200 displays the calculated degree of achievement of brushing on the other side of the screen on which the brushing guide content is displayed. Here, the terminal 200 calculates the overall brushing achievement for at least one brushing area in which brushing has been performed so far, in addition to the degree of achievement for each brushing area, and displays the calculated overall brushing achievement on the screen on which the brushing guide content is displayed. It can also be displayed on the other side.

As an example, when it is confirmed that the first user is not brushing teeth using the first toothbrush as a result of the confirmation (or when there is no change in the location information of the first toothbrush), the second terminal Based on the location information of the first toothbrush stored in relation to the first brushing area to the location information of the 5000th toothbrush and the first accumulated brushing time (for example, 5 seconds), a preset first normal brushing time (eg, 5 seconds) For example, a value (for example, 0 second) obtained by adding a value (for example, 0 second) corresponding to the non-brushing state to the previous value of 0 second) is calculated.

In addition, the second terminal checks (or calculates/calculates) the first total brushing time (eg, 5 seconds) related to the first brushing area of the Lala Chikasong being output.

In addition, the second terminal precedes the summed (or accumulated) first normal brushing time (for example, 0 seconds) and the confirmed first total brushing time (for example, 5 seconds) [Equation 5] is applied to calculate a first degree of brushing achievement (eg 0/5*100 = 0%) in relation to the first brushing area.

In addition, the second terminal calculates the total brushing achievement (eg, 0/5*100 = 0%) up to the first brushing area, which is the first brushing order among the 13 ordered brushing areas.

In addition, as shown in FIG. 5 , the second terminal provides guide information 510 indicating that correct brushing should be performed on one side of the first brushing guide screen related to the output Lala chicasong, the first brushing guide The calculated first brushing achievement (eg 0%) 520 on the other side of the screen, the calculated total brushing achievement (eg 0%) 530 on the other side of the first brushing guide screen is displayed (S360).

In addition, as a result of the confirmation (or the determination result), when the user is brushing teeth using the toothbrush 100 (or when the amount of change of the location information of the toothbrush is smaller than the threshold value / The amount of change of the location information of the toothbrush If it exists within the threshold range), the terminal 200 determines the user based on the stored (or accumulated) location information of a plurality of toothbrushes related to the specific brushing area and a specific brushing area corresponding to the corresponding brushing guide content. Determines (or confirms) whether a specific brushing area has been brushed.

That is, as a result of the confirmation (or the determination result), when the user is brushing teeth using the toothbrush 100 , the terminal 200 displays the brushing currently being output through the terminal 200 among the plurality of preset brushing areas. The specific brushing area that is the previous brushing area than the brushing area corresponding to the guide content is identified.

In addition, in order to determine whether the user has normally brushed the specific brushing area with respect to the identified specific brushing area, the terminal 200 may be within a preset toothbrush angle range with respect to the identified specific brushing area. It is determined whether the location information of the plurality of toothbrushes stored in relation to the specific brushing area is included. At this time, the terminal 200 manages (or stores) a toothbrush angle range (eg, including an x-axis range, a y-axis range, etc.) preset for each of the plurality of brushing areas. Here, the preset toothbrush angle range is a result value according to an experiment, as shown in Table 1 above, and the average range ( or average value).

At this time, the terminal 200 determines the amount of change in the position information of the toothbrush according to the position information of the plurality of toothbrushes stored in relation to the specific brushing area and the amount of change in reference according to the brushing method preset (or stored) in relation to the specific brushing area. Based on the , it may be determined whether the user has normally brushed a specific brushing area. Here, the brushing method preset in relation to the specific brushing area may be a brushing method related to song lyrics stored in advance in response to the specific brushing area (for example, including round, squash, etc.).

That is, the terminal 200 determines that the change amount of the position information of the toothbrush according to the position information of the plurality of toothbrushes related to the specific brushing area is identical to (or the same as) the standard change amount corresponding to the brushing method according to the song lyrics of the specific brushing area. / It is determined whether it exists within the preset error range).

In this way, the terminal 200 determines whether the position information of the plurality of toothbrushes is included within the preset toothbrush angle range for the specific brushing area, and the amount of change in the location information of the plurality of toothbrushes is the specific brushing area. It is possible to determine whether the user has normally brushed the specific brushing area by determining whether the area coincides with a preset reference change amount (or exists within an error range), and the like.

As an example, when it is confirmed that the first user is brushing using the first toothbrush as a result of the confirmation (or the change amount of the location information of the plurality of first toothbrushes is confirmed as being within the threshold range) When), the second terminal is a brushing area one step before the second brushing area (eg, the outer surface of the front teeth) related to the Lala chicas song currently being output through the second terminal among the 13 preset brushing areas. 1 Check the brushing area (eg the outside of the left molar).

In addition, the second terminal is a preset first toothbrush angle range (for example, the x-axis range -60 degrees to 80 degrees, the y-axis range - 60 degrees to 0 degrees) in relation to the first brushing area, the location information of the first toothbrush to the location information of the 5000 toothbrushes are each included, and the location information of the first toothbrush to the location information of the 5000 toothbrushes. It is determined whether a plurality of variations between the location information is in a state consistent with a first reference variation related to the first brushing area. Here, the first reference change amount may be a change amount in a rotational form for confirming whether brushing is performed in a round manner in relation to song lyrics in the first brushing area ( S370 ).
