[0009] Hereinafter, each embodiment of the present disclosure will be described with reference to the accompanying drawings. Note that, in the description of the specification and drawings relating to each embodiment, components having substantially the same or corresponding functional configurations may be designated by the same reference numerals, and redundant description may be omitted.

[0010] To facilitate understanding, the scale of each part in the drawings may differ from the actual scale. Directions such as parallel, right-angled, orthogonal, horizontal, vertical, up-down, left-right, and the like are permitted to have deviations that do not impair the effects of the embodiments. The shape of corners is not limited to right angles and may be rounded. Parallel, right-angled, orthogonal, horizontal, and vertical may include approximately parallel, approximately right-angled, approximately orthogonal, approximately horizontal, and approximately vertical.

[0011] First Embodiment A beauty system will be described as a first embodiment. Fig. 1 is a diagram showing an overview of a beauty system 1, which is an example of a beauty system according to the first embodiment.

[0012] The beauty system 1 includes a face shape measuring device 10 and a beauty device 20.

[0013] [Facial shape measuring device 10] The face shape measuring device 10 measures the face shape of a user. Even when a beauty device 20 or the like is applied to the face, the face shape often changes only slightly, and the user may not notice any improvement in the face shape. In such cases, the user may stop using the beauty device 20 because they feel that they are not seeing any improvement in the face shape.

[0014] The beauty system 1 uses the face shape measuring device 10 to evaluate the face shape when using the beauty device 20, thereby enabling confirmation of the effect of the beauty device 20.

[0015] The face shape measuring device 10 includes an imaging unit 11, an analysis unit 12, a determination unit 13, and a communication unit 18. The face shape measuring device 10 can use, for example, the device described in International Publication No. 2021 / 241475.

[0016] (Image capture unit 11) The imaging unit 11 generates data of an image (three-dimensional facial image) representing the three-dimensional shape of the user's face. The imaging unit 11 is a device capable of capturing 3D (three-dimensional) images. More specifically, the imaging unit 11 captures one or more images SIG in states where the gravity vector acting on the user's facial tissue is different. In other words, the imaging unit 11 captures images in states where the magnitude or direction of gravity on the facial tissue, or both, are different, preferably in states where the directions of gravity are different. For example, the imaging unit 11 generates data of three-dimensional facial image when the user's face is in a horizontal position (when the midline of the face is stationary at a right angle to the direction of gravity) and when the user's face is in a vertical position (when the midline of the face is stationary parallel to the direction of gravity).

[0017] (Analysis Department 12) The analysis unit 12 is a computer (e.g., a personal computer, tablet, smartphone, etc.) that calculates information used for facial shape evaluation based on the data generated by the imaging unit 11. The analysis unit 12 calculates the amount of change in the three-dimensional shape of the user's face when comparing multiple facial images captured in states where the gravity vector acting on the user's facial tissue is different. For example, the analysis unit 12 calculates the amount of gravity swelling (VC swelling) and the amount of gravity collapsing (VC shrinking) (described in detail below) based on the change in three-dimensional shape between a three-dimensional shape facial image when the user's face is in a horizontal position and a three-dimensional shape facial image when the user's face is in a vertical position.

[0018] (Judgment part 13) When the three-dimensional facial images acquired by the imaging unit 11 are images taken in a horizontal position and a vertical position, and the analysis unit 12 calculates the amount of gravitational swelling (VCswelling) and the amount of gravitational depression (VCshrinking), the determination unit 13 further calculates the amount of intra-facial movement sagging (Sf) and the amount of anterior-posterior cheek sagging (Sc) (described in detail later).The determination unit 13 then evaluates the facial shape using the amount of intra-facial movement sagging (Sf) and the amount of anterior-posterior cheek sagging (Sc) as indicators.The following describes an example in which the imaging unit 11 captures and compares facial images of the user in a horizontal position and a vertical position.

[0019] The determination unit 13 acquires the gravity swelling amount (VCswelling) and gravity collapsing amount (VCshrinking) calculated by the analysis unit 12. Then, the determination unit 13 stores the acquired gravity swelling amount (VCswelling) and gravity collapsing amount (VCshrinking) in the memory unit 15. Note that the memory unit 15 can also store the results calculated by the determination unit 13, as well as information about the user input from outside.

[0020] The determination unit 13 calculates the amount of intra-facial movement sagging (Sf) and the amount of front-to-back cheek sagging (Sc) from the amount of gravitational swelling (VCswelling) and the amount of gravitational depression (VCshrinking). The calculated amount of intra-facial movement sagging (Sf) and the amount of front-to-back cheek sagging (Sc) are stored in the storage unit 15.

[0021] Here, the amount of gravitational swelling (VCswelling), the amount of gravitational depression (VCshrinking), the amount of intra-facial sagging (Sf), and the amount of front-to-back cheek sagging (Sc) will be described in more detail. Figures 2 and 3 are diagrams illustrating the processing in a beauty system 1, which is an example of a beauty system according to this embodiment.

[0022] A three-dimensional face image (first three-dimensional face image) of the user's face when it is in a horizontal position and a three-dimensional face image (second three-dimensional face image) of the user's face when it is in a vertical position are acquired, and the three-dimensional shape when it is in a horizontal position is compared with the three-dimensional shape when it is in a vertical position. Comparing the three-dimensional shape when it is in a horizontal position with the three-dimensional shape when it is in a vertical position, gravitational swelling can be seen in the area within the dashed line in the face image shown in Figure 2. That is, the volume of the area within the dashed line in Figure 2 is larger when it is in a vertical position than when it is in a horizontal position. The difference in volume between the two areas (i.e., horizontal and vertical positions) of the area that has a larger volume when it is in a vertical position is defined as the gravitational swelling amount (VCswelling).

[0023] Furthermore, a three-dimensional facial image of the user's face when it is in a horizontal position and a three-dimensional facial image of the user's face when it is in a vertical position are acquired, and the three-dimensional shape when it is in a horizontal position is compared with the three-dimensional shape when it is in a vertical position. When the three-dimensional shape when it is in a horizontal position is compared with the three-dimensional shape when it is in a vertical position, gravity depression can be seen in the area within the dashed line in Figure 3. That is, the volume of the area within the dashed line in Figure 3 is smaller when it is in a vertical position than when it is in a horizontal position. The difference in volume between the two areas (i.e., the horizontal and vertical positions) where the volume is smaller when it is in a vertical position is defined as the amount of gravity depression (VCshrinking).

[0024] Furthermore, two types of sagging (the "amount of intrafacial sagging (Sf)" and the "amount of anterior-posterior cheek sagging (Sc)") can be calculated from the amount of gravitational bulge (Figure 2) (VCswelling) and the amount of gravitational depression (Figure 3) (VCshrinking) using the following formula (1). Formula (1) below shows that, with the amount of gravitational depression (VCshrinking) on ​​the x-axis and the amount of gravitational bulge (VCswelling) on ​​the y-axis, the two types of sagging (the "amount of intrafacial sagging (Sf)" and the "amount of anterior-posterior cheek sagging (Sc)") can be quantified by converting the coordinates 45 degrees counterclockwise. The relationship between gravitational bulge and gravitational depression and the "amount of intrafacial sagging (Sf)" and the "amount of anterior-posterior cheek sagging (Sc)" is also shown in Figure 4.

[0025]

number

[0026] Intra-facial shift sagging is sagging that occurs from the upper to the lower cheek, while anterior-posterior cheek sagging is sagging other than that that occurs from the upper to the lower cheek (for example, sagging that occurs when the cheek around the mouth deforms, causing the cheek to shift back and forth from the oral cavity side). Figure 5 shows the location where typical intra-facial shift sagging occurs, and Figure 6 shows the location where typical anterior-posterior cheek sagging occurs, each indicated by an arrow.

[0027] Referring again to Fig. 1, the determining unit 13 evaluates the type and degree of sagging using the amount of intra-facial sagging (Sf) and the amount of front-to-back cheek sagging (Sc) as indicators.

[0028] Based on the knowledge that there are two factors that make up sagging, namely, "intra-facial sagging" and "front-rear cheek sagging," the facial shape measuring device 10 can evaluate facial shape according to the change in facial volume between when a person's face is in a horizontal position and when it is in a vertical position.

[0029] In facial shape evaluation using the facial shape measuring device 10, in addition to "intra-facial sagging" and "front-rear cheek sagging," a third factor that contributes to the appearance of sagging, the sagging skin coefficient, can also be used. The sagging skin coefficient (Cs) can be defined using the following formula (2) from the relationship between the amount of gravitational swelling (VCswelling) and the visual score (visual evaluation, also called Sss).

[0030]

number

[0031] The visual score (Sss) is a numerical representation of the visual assessment of sagging. The visual score (Sss) is calculated by an evaluator's judgment of which of the reference photographs 1 to 5 a person's face most closely resembles, as described, for example, in T. Ezure, J. Hosoi, S. Amano, and T. Tsuchiya, Skin Research and Technology 2009; 15: 299-305. For example, the visual score (Sss) is calculated from an oblique profile image (an image of the face taken from a 45-degree angle to the left and right from the front) of the subject's face in a vertical position (i.e., a state in which the midline of the face is held stationary parallel to the direction of gravity). The visual score (Sss) may be calculated using a trained model generated by machine learning using the oblique profile image for which the visual score was determined as training data. The visual score is determined for each of the upper cheek, lower cheek, and posterior cheek regions, but may also be newly generated by averaging any of these. The visual score (Sss) is calculated by averaging the visual scores, particularly in the upper and lower cheeks, and indicates the apparent sagging of the upper and lower cheeks.

[0032] Furthermore, the following formula (3) has been found from the relationship between the amount of gravitational swelling (VCswelling), the amount of intra-facial movement sagging (Sf), and the amount of front-to-back cheek sagging (Sc).

[0033]

number

[0034] From the above equations (2) and (3), the relationship between the apparent sagging (i.e., the visual score (Sss)), the sagging skin coefficient (Cs), the amount of intra-facial sagging (Sf), and the amount of anterior-posterior cheek sagging (Sc) can be expressed by the following equation (4).

[0035]

number

[0036] Furthermore, it is known that the sagging skin coefficient (Cs) correlates with the skin viscoelasticity parameters acquired by the viscoelasticity acquisition device. Therefore, the sagging skin coefficient can be calculated using one or more of the skin viscoelasticity parameters acquired by the viscoelasticity acquisition device.

[0037] (Communications Department 18) The communication unit 18 communicates with the beauty device 20. By communicating with the beauty device 20 via the communication unit 18, the face shape measuring device 10 can change the settings of the beauty device 20, for example.

[0038] The results of measurements using the face shape measuring device 10 are shown in FIG. 15. FIG. 15 is a diagram showing the results of measurements using the face shape measuring device 10 according to this embodiment. FIG. 15 shows the results of evaluating facial sagging using the face shape measuring device 10 for about one month (30 days). The horizontal axis represents the number of days elapsed, and the vertical axis represents an index showing sagging. As shown in FIG. 15, the face shape measuring device 10 according to this embodiment can perform measurements with such high precision that changes in sagging over time can be measured.

[0039] Therefore, by reflecting the highly accurate measurement results obtained by the facial shape measuring device 10 in the settings of the beauty device 20, the beauty system 1 is able to further improve the facial shape by eliminating facial sagging, tightening the face, etc. when the beauty device 20 is applied.

[0040] The processes of the analysis unit 12 and the determination unit 13 in the face shape measuring device 10 may be performed by, for example, a server connected to a network. For example, the three-dimensional face image acquired by the imaging unit 11 of the face shape measuring device 10 in the beauty system 1 may be transmitted to the server, where the analysis may be performed, and the result of the analysis may be transmitted to the face shape measuring device 10.

[0041] [Beauty equipment 20] The beauty device 20 is applied to the skin of a subject. The beauty device 20 applies electrical or physical stimuli to the skin of the subject. For example, the beauty device 20 applies stimuli such as heat, radio waves, light, electricity, electric pulses, ultrasonic vibrations, and motor vibrations to the skin of the subject. The beauty device 20 also supplies a cosmetic agent such as a lotion. While the following describes a case where all of the above are included, the beauty device 20 may be provided with at least one of the above.

[0042] The beauty device 20 includes a control unit 21, a radio wave irradiation unit 22R, a light irradiation unit 22L, an electricity application unit 22E, an electric pulse application unit 22P, an ultrasonic vibration unit 22U, a motor vibration unit 22V, a cosmetic supply unit 22D, and a communication unit 28.

[0043] (Control unit 21) The control unit 21 controls the entire beauty device 20.

[0044] (Radio wave irradiation section 22R) The radio wave irradiator 22R irradiates the skin of the subject with radio waves STR. The radio wave irradiator 22R irradiates the skin of the subject with radio waves of, for example, about 200 kHz to 300 MHz. By irradiating the skin of the subject with radio waves, for example, the skin of the subject is heated. The radio wave irradiator 22R includes an antenna for irradiating the radio waves and a power source for supplying power to the antenna.

[0045] The radio wave radiating section 22R is controlled by the control section 21, and is thereby able to change, for example, the intensity or frequency of the radio waves it radiates.

[0046] (Light irradiation part 22L) The light irradiator 22L irradiates the skin of the subject with light STL. The light irradiator 22L irradiates, for example, infrared light onto the skin of the subject. By irradiating the skin of the subject with light, for example, the skin of the subject is heated. The light irradiator 22L includes a light emitting element, for example, an LED (Light Emitting Diode). The light irradiator 22L irradiates, for example, light in the infrared region.

[0047] The light irradiating unit 22L is controlled by the control unit 21, and is thereby able to change, for example, the intensity or wavelength (color) of the irradiated light.

[0048] (Electrical application unit 22E) The electric applicator 22E applies an electric stimulus STE to the skin of the subject. The electric applicator 22E includes, for example, at least two electrodes that contact the skin. The electric applicator 22E applies a constant voltage between one electrode and the other electrode. By applying a constant voltage between the one electrode and the other electrode, the electric applicator 22E can promote the penetration of a liquid such as a cosmetic into the skin.

[0049] The electric applying unit 22E is controlled by the control unit 21, and can change the voltage between the electrodes, for example.

[0050] (Electric pulse application unit 22P) The electric pulse application unit 22P applies an electric stimulus STP to the skin of the subject. The electric pulse application unit 22P includes, for example, at least two electrodes that contact the skin. The electric pulse application unit 22P applies an electric pulse between one electrode and the other electrode. By applying an electric pulse between the one electrode and the other electrode, the electric pulse application unit 22P can stimulate a muscle, for example, and forcibly move the muscle to which the electric pulse is applied.

[0051] The electric pulse applying section 22P is controlled by the control section 21, and is thereby able to change, for example, the pulse voltage, the pulse frequency, or the duty ratio.

[0052] (Ultrasonic vibration section 22U) The ultrasonic vibration unit 22U applies ultrasonic vibrations STU to the skin of the subject. The ultrasonic vibration unit 22U includes a piezoelectric element that generates ultrasonic vibrations and a power source that supplies power to the piezoelectric element. The ultrasonic vibration unit 22U vibrates the piezoelectric element, thereby vibrating, for example, the skin.

[0053] The ultrasonic vibration unit 22U is controlled by the control unit 21, so that, for example, the amplitude or frequency of the ultrasonic vibration can be changed.

[0054] (Motor vibration part 22V) The motor vibration unit 22V applies vibration STV to the skin of the subject. The motor vibration unit 22V includes a motor that generates vibrations and a power supply that supplies power to the motor. The motor vibration unit 22V generates vibrations by rotating the motor, and vibrates the skin, for example.

[0055] Motor vibration section 22V is controlled by control section 21, so that, for example, the amplitude or frequency of vibration can be changed.

[0056] In the above example, vibration is generated by a motor, but a component other than a motor may be used to generate vibration.

[0057] (Cosmetic supply unit 22D) The cosmetic supply unit 22D supplies a cosmetic STD such as a beauty serum to the skin of the subject. The cosmetic supply unit 22D includes a storage unit that stores the cosmetic to be applied to the skin of the subject, and a supply unit that supplies the cosmetic from the storage unit.

[0058] The cosmetic supply unit 22D is controlled by the control unit 21, so that, for example, the type or amount of cosmetic to be supplied can be changed.

[0059] The beauty device 20 may apply heat to the skin of the subject as a stimulus. For example, the beauty device 20 may include a heater such as an electric heating wire that generates heat and a power source that supplies power to the heater. The control unit 21 may change, for example, the amount of heat of the heater or the temperature of a substrate that comes into contact with the skin.

[0060] (Communications Department 28) The communication unit 28 communicates with the face shape measuring device 10. By communicating with the face shape measuring device 10 via the communication unit 28, the beauty device 20 can receive measurement results from the face shape measuring device 10, for example.

[0061] <Beauty System 1 Treatment> A description will be given of the processing of the beauty system 1. By describing the processing of the beauty system 1, steps included in the beauty method using the beauty system 1 will be described.

[0062] First, the imaging unit 11 of the face shape measuring device 10 in the beauty system 1 acquires multiple face images captured under different gravity vectors acting on the subject's facial tissues. The analysis unit 12 and determination unit 13 of the face shape measuring device 10 in the beauty system 1 then measure the face shape of the subject using the acquired multiple face images. Based on the measurement results, the face shape measuring device 10 in the beauty system 1 then changes settings related to stimuli to be applied to the subject's face in the beauty device 20, and applies the stimuli to the subject's face. Based on the measurement results, the face shape measuring device 10 also supplies cosmetics from the beauty device 20 and applies them to the subject's face.

[0063] <Summary> According to the beauty system of the first embodiment, by using the measurement results of the face shape by the face shape measurement device, it is possible to further improve the face shape by eliminating sagging of the face, tightening the face, and so on.

[0064] The imaging unit 11 is an example of an acquisition unit, and the analysis unit 12 and determination unit 13 are examples of a measurement unit.

[0065] Second Embodiment A system using a face shape measuring device and a server will be described as the second embodiment. Fig. 7 is a diagram showing an overview of a system 2 which is an example of a system according to the second embodiment.

[0066] As explained in the first embodiment, the face shape measuring device according to this embodiment can measure face shape with higher accuracy. Therefore, in the system according to the second embodiment, the measurement results by the face shape measuring device are used to encourage the user to use the beauty device or beauty product repeatedly for a long period of time.

[0067] When a user uses a beauty device or beauty product, they are required to use it continuously for a certain period of time in order to realize the effects. However, if the user does not realize the effects of the beauty device or beauty product, the user may stop using the beauty device or beauty product. Therefore, the system according to the second embodiment encourages the user to realize the effects by using the face shape measuring device according to the present embodiment, which is capable of measuring face shape with high accuracy.

[0068] The system according to the second embodiment provides a reward to a user (subject) who uses an evaluation target (beauty equipment or beauty product (e.g., cosmetics)) that is applied to the face and who continuously uses the face shape measuring device to evaluate the evaluation target. By providing a reward to a user (subject) who continuously uses the face shape measuring device and evaluates the evaluation target, the system according to the second embodiment encourages the user (subject) to continue using the system and can obtain long-term data about the evaluation target.

[0069] The system 2 includes a face shape measuring device 10, a beauty device 20, a server 110, a server 120, and a server 130.

[0070] The face shape measuring device 10, the server 110, the server 120, and the server 130 are connected to each other via a network NW. The network NW is, for example, a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, etc.

[0071] It should be noted that the devices connected to the network NW are not limited to those mentioned above, and for example, a PC (Personal Computer) or a mobile terminal (for example, a mobile phone or a smartphone) used by a user may also be connected.

[0072] [Server 110] The server 110 is a server that manages the measurement results of the face shape measuring device 10. The server 110 acquires the measurement results measured by the face shape measuring device 10. The server 110 performs processing based on the measurement results measured by the face shape measuring device 10. For example, the server 110 grants a benefit to a user determined to be continuously using the face shape measuring device 10. The server 110 issues instructions to the server 120 or the server 130 based on the acquired measurement results.

[0073] The server 110 is configured by, for example, a microprocessing unit including a CPU (Central Processing Unit), RAM (Random Access Memory), and ROM (Read Only Memory). The server 110 performs processing by the CPU expanding a program recorded in the ROM into the RAM and executing it. The same applies to the servers 120 and 130.

[0074] [Server 120] Server 120 is a server that manages the delivery of prizes. When server 120 receives an instruction to deliver a prize from server 110, server 120 performs processing to deliver the prize. For example, server 120 instructs the creation of documents, delivery labels, etc. required to deliver the prize. Server 120 also instructs the packaging of the prize, etc. Then, server 120 instructs the delivery of the prize.

[0075] [Server 130] The server 130 is a server that manages the shipping of the evaluation target (beauty device or beauty product). When the server 130 receives an instruction to ship the evaluation target from the server 110, the server 130 performs processing to ship the evaluation target. For example, the server 130 instructs the creation of documents, shipping labels, etc. required to ship the evaluation target. Furthermore, the server 120 instructs the server 120 which evaluation target to package.

[0076] <Processing in System 2> [Example 1] The following describes a first example of processing in the system 2. Fig. 8 is a flow diagram illustrating a first example of processing in the system 2, which is an example of a system according to the second embodiment.

[0077] (Step S10) The server 110 in the system 2 acquires the measurement results from the face shape measuring device 10. For example, when the face shape measuring device 10 measures the skin of a subject, the face shape measuring device 10 notifies the server 110 that the measurement results are available. Then, upon receiving the notification, the server 110 acquires the measurement results from the face shape measuring device 10.

[0078] When the server 110 acquires the measurement results from the face shape measuring device 10, the measurement results may be transmitted from the face shape measuring device 10 to the server 110 using, for example, a non-fungible token (NFT). By using a non-fungible token (NFT), it is possible to prevent data tampering and increase the reliability of the data.

[0079] For example, the server 110 acquires the measurement results from the face shape measuring device 10 once a day or once every few days.

[0080] (Step S20) Next, server 110 in system 2 determines whether measurement results have been acquired a predetermined number of times. If measurement results have been acquired a predetermined number of times (YES in step S20), server 110 proceeds to step S30. If measurement results have not been acquired a predetermined number of times (NO in step S20), server 110 returns to step S10 and repeats the process.

[0081] By repeating steps S10 and S20, server 110 can obtain measurement results a predetermined number of times or more.

[0082] (Step S30) The server 110 performs processing to grant a reward to the subject. Examples of rewards granted to the subject are shown below.

[0083] (1) Full or partial refund of expenses For example, if the evaluation target is cosmetics, beauty equipment, etc., the cost incurred in purchasing the evaluation target may be refunded in full or in part. Also, if the evaluation target is beauty services, etc., the cost of the beauty services may be refunded in full or in part.

[0084] (2) Gift of an item bundled with the subject of evaluation or a discount coupon for that item For example, if a beauty device is being used as the evaluation target, a consumable product (e.g., a beauty serum) that is used as a set with the beauty device may be given as a gift. Also, if a beauty device is being used as the evaluation target, a discount coupon for a consumable product (e.g., a beauty serum) that is used as a set with the beauty device may be given as a gift.

[0085] (3) Certified as a Preferred Customer For example, the subject may be certified as a preferred customer and may be eligible for preferential sales, etc.

[0086] (4) Preferential purchase of new products For example, subjects may be given the right to purchase before the release date.

[0087] For example, when shipping an item, the server 110 may instruct the server 120 to ship the item. The server 120 performs processing to ship (send) the item based on the instruction from the server 110.

[0088] By performing the process as in the first example, the system 2 can encourage the user (subject) to continue using the evaluation object (face shape measuring device).

[0089] [Example 2] The following describes a second example of the processing in the system 2. Fig. 9 is a flow diagram illustrating a second example of the processing in the system 2, which is an example of a system according to the second embodiment.

[0090] In the second example, in addition to the number of times that the evaluation results are obtained in the first example, the content of the evaluation results is also subject to judgment.

[0091] For steps S10 and S20, the explanation for the first example is to be referred to and will be omitted here.

[0092] (Step S130) When the measurement results have been acquired a predetermined number of times (YES in step S20), the server 110 determines whether the measurement results have improved over time. For example, the server 110 determines whether the evaluation index calculated from the measurement results has improved over time. If the evaluation results have improved over time (YES in step S130), the server 110 proceeds to step S140. If the evaluation results have not improved over time (NO in step S130), the server 110 proceeds to step S150.

[0093] (Step S140) The server 110 performs processing to grant the benefit to the subject. For specific processing, refer to the description of step S30, and the description will be omitted here.

[0094] (Step S150) The server 110 resets the number of repetitions, and then returns to step S10 to repeat the process.

[0095] By performing the process as in the second example, the system 2 can encourage the user (subject) to continue using the evaluation object (face shape measuring device). Also, by performing the process as in the second example, the system 2 can encourage the user (subject) to use the evaluation object (face shape measuring device) appropriately.

[0096] [Example 3] The following describes a third example of the processing in the system 2. Fig. 10 is a flow diagram illustrating a third example of the processing in the system 2, which is an example of the system according to the second embodiment.

[0097] In the third example, a beauty device is used as the evaluation target. In the third example, the settings of the beauty device are changed, whereas in the first example, a special benefit is given.

[0098] For steps S10 and S20, the description of the first example should be referred to and will not be repeated here.

[0099] (Step S230) When the measurement results have been acquired the predetermined number of times (YES in step S20), the server 110 instructs the beauty device 20 to change the settings via the face shape measuring device 10. Note that the server 110 may also instruct the beauty device 20 directly to change the settings.

[0100] For example, the server 110 may instruct the beauty device 20 to change the settings regarding the stimulation applied to the skin. Furthermore, the server 110 may, for example, change the upper limit value of the stimulation applied by the beauty device 20. By changing the upper limit value of the stimulation applied by the beauty device 20, for example, the beauty device 20 may be able to apply a stronger stimulation.

[0101] Furthermore, for example, the server 110 may evaluate the content of the measurement results and customize the settings of the beauty device 20 to be more effective.

[0102] By performing processing as in the third example, the system 2 can improve the function or action of the beauty device so that the user (subject) can realize the effect of the evaluation object. By improving the function or action of the beauty device, the system 2 can make the user (subject) realize the effect and encourage continued use of the evaluation object (face shape measuring device).

[0103] [Example 4] The following describes a fourth example of processing in the system 2. Fig. 11 is a flow diagram illustrating a fourth example of processing in the system 2, which is an example of a system according to the second embodiment.

[0104] In the fourth example, whereas in the first example a benefit was given, the evaluation object itself is exchanged.

[0105] For steps S10 and S20, the explanation for the first example is to be referred to and will be omitted here.

[0106] (Step S340) When the measurement results have been acquired a predetermined number of times (YES in step S20), the server 110 may replace the currently used evaluation target with a new evaluation target or a different evaluation target.

[0107] The server 110 may, for example, perform processing to send a new evaluation target of the same model to the test subject. Specifically, the server 110 instructs the server 130 that manages the evaluation targets to send a new evaluation target to the test subject. The server 130 performs processing to send the new evaluation target to the test subject.

[0108] Furthermore, the server 110 may perform processing to send, for example, a more sophisticated evaluation target to the subject. Specifically, the server 110 instructs the server 130 that manages the evaluation targets to send another evaluation target to the subject. The server 130 performs processing to send to the subject another evaluation target that is different from the evaluation target currently being used.

[0109] By performing processing as in the fourth example, the user (subject) can obtain a new or different evaluation object, and therefore, system 2 can give the user (subject) a sense of value and encourage continued use of the evaluation object (face shape measurement device).

[0110] In step S20, it is determined whether the measurement results have been obtained a predetermined number of times, but the criteria for determination are not limited to the number of times. For example, in step S20, the criteria for determining whether to grant a special benefit may be the usage (e.g., whether the recommended usage is followed faithfully, whether the usage is correct, etc.) or the frequency of use (e.g., whether the device is used in the morning and evening, etc.).

[0111] <Summary> According to the system of the second embodiment, it is possible to encourage subjects to continue using the evaluation target.

[0112] The server 120 is an example of a second server, and the server 130 is an example of a third server.

[0113] Third Embodiment A system according to the third embodiment will now be described. As explained in the first embodiment, the face shape measuring device according to this embodiment enables more accurate measurement of face shape. Therefore, the system according to the third embodiment presents a highly reliable review of the cosmetic effect of the evaluation target. Below, the system according to the third embodiment will be described based on System 2.

[0114] The system of the third embodiment publishes reviews written by users (subjects) who use the evaluation target (beauty equipment or beauty product (e.g., cosmetics)) applied to the face, along with the measurement results measured using a face shape measurement device.

[0115] A description will be given of processing according to the third embodiment in the system 2. Fig. 12 is a flow diagram illustrating processing in the system 2, which is an example of a system according to the third embodiment.

[0116] For steps S10 and S20, the description of the first example in the second embodiment is to be referred to, and the description will be omitted here. By steps S10 and S20, a plurality of measurement results are acquired during a predetermined period. In other words, by steps S10 and S20, the results of a plurality of measurements performed during a certain period are acquired.

[0117] (Step S430) When the measurement results have been acquired the predetermined number of times (YES in step S20), the server 110 creates a review for the evaluation target.

[0118] The server 110 has a function of displaying reviews of the evaluation target as a web page. The server 110 transmits the created web page to another terminal connected to the network NW. The server 110 also has a function of receiving the review content of the evaluation target from the terminal owned by the subject via the network NW.

[0119] An example of a web page displayed by the server 110 will be described below. Fig. 13 is a diagram illustrating page P1, which is an example of an evaluation page created by the server 110. Page P1 has a display R1 that displays the measurement results and a display T1 that displays reviews from the subjects.

[0120] Display R1 displays, for example, the measurement results in a graph, and display T1 displays the review in text.

[0121] The server 110 may also display multiple evaluation targets. FIG. 14 is a diagram illustrating page P2, which is an example of an evaluation page created by the server 110. Page P2 has a view V21 (first view) showing a review (first review) of a first evaluation target, and a view V22 (second view) showing a review (first review) of a second evaluation target different from the first evaluation target. View V21 has a display R21 displaying the measurement results of a subject who applied the first evaluation target, and a display T21 displaying the review from the subject. View V22 has a display R22 displaying the measurement results of a subject who applied the second evaluation target, and a display T22 displaying the review from the subject.

[0122] A view V21 (first view) showing a review (first review) of a first evaluation target and a view V22 (second view) showing a review (first review) of a second evaluation target different from the first evaluation target are displayed side by side.

[0123] For example, the server 110 may change the subject and generate an evaluation page including a first review based on multiple first measurement results by a first subject and a second review based on multiple second measurement results by a second subject.

[0124] Also, for example, the server 110 may change the evaluation object and generate an evaluation page that includes a first review based on multiple first measurement results by a subject who applied a first evaluation object, and a second review based on multiple second measurement results by a subject who applied a second evaluation object.

[0125] The server 110 may, for example, create an evaluation page that lists and displays a list of measurement results collected from various evaluation subjects or evaluators. The server 110 may also make the evaluation page that lists and displays the measurement results available for public viewing. If the evaluation page is made available for public viewing, the evaluation page is created in such a way that personal information cannot be identified from the evaluation data.

[0126] <Summary> According to the system of the third embodiment, highly reliable reviews can be presented by displaying highly accurate measurement results together.

[0127] The embodiments disclosed herein should be considered in all respects as illustrative and not restrictive. The above-described embodiments can be modified and improved in various ways without departing from the scope and spirit of the appended claims. The features described in the above-described embodiments can be configured in other ways within a consistent range, and can be combined within a consistent range. [Explanation of symbols]
