DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] <First embodiment> Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] [Online test system configuration] First, an online test system SYS according to the first embodiment will be described. FIG. 1 is a system configuration diagram showing an example of the configuration of an online test system SYS according to the first embodiment of the present invention. The online test system SYS includes a content providing apparatus 1, an online test apparatus 2, and a feedback device 3. The content providing device 1, the online test device 2, and the feedback device 3 are communicatively connected via a network NW.

[0016] The online test system SYS according to this embodiment is a tactile feedback system that acquires physical property data of a product, converts the physical property data into sensory data adapted to a device, and feeds back to the device the tactile feel of the product according to the sensory data.

[0017] Specifically, the online test system SYS according to the present embodiment is an online tester system that provides feedback to a user of the feel of a product in a real space in a virtual space, an augmented space, or a composite space. The product is, for example, food, cosmetics, etc. In the present embodiment, a case where the product is cosmetics will be described as an example.

[0018] A virtual space, an augmented space, or a mixed space is a simulated environment (space) created by a computer in virtual reality, augmented reality, or mixed reality, and is also called, for example, a metaverse or a virtual space. Cosmetics include basic cosmetics (skin care items) such as lotion introducers, lotions, milks, serums, and moisturizing creams, as well as make-up cosmetics such as foundations, eyeliners, eyeshadows, lipsticks, and blushes.

[0019] More specifically, the online test system SYS is a system in which a user's avatar can experience the feel of a cosmetic product in the real space by holding a tester capable of trying out the cosmetic product in a drugstore or the like in the virtual space, the augmented space, or the composite space. Here, the cosmetic product in the virtual space, the augmented space, or the composite space corresponds to the cosmetic product in the real space.

[0020] The content providing device 1 is a content server that provides a simulated space such as a virtual space, an extended space, or a composite space.

[0021] The online test device 2 is a server that provides customized content in the simulated space provided by the content providing device 1. Specifically, the online test device 2 is a server that operates, for example, a drugstore that handles cosmetics in the simulated space. The online test device 2 converts physical property data that represents the feel of the cosmetics in the real space into sensory data that represents the feel of the cosmetics in the virtual space, the extended space, or the composite space. The physical property data is, for example, analytical data that represents the properties of the cosmetics, or viscoelasticity data that represents the viscoelasticity of the cosmetics measured by a rheometer. The viscoelasticity data is, for example, flow curves, strain dependency, frequency dependency measurement data, data that represents the relationship between the viscosity and shear rate for each cosmetic product, and the like. The sensory data is, for example, data that represents the feel of the cosmetics, such as the ease of crumbling, freshness, refreshing feeling, good spreadability, slickness, moist feeling, and stickiness.

[0022] The feedback device 3 is a device that feeds back a tactile sensation to the user. For example, the feedback device 3 includes a feedback device that feeds back a tactile sensation to the user, and a control device that controls the feedback device. In this embodiment, an example will be described in which a terminal device serving as a control device and the feedback device are connected to function as one unit. The terminal device is, for example, a smartphone, a tablet terminal, a personal computer, a mobile phone, or other terminal device. The feedback device 3 feeds back the tactile sensation of the cosmetic product in the real space to the user in the virtual space, the augmented space, or the composite space based on sensory data.

[0023] In this way, the online test system SYS according to this embodiment can provide feedback of the texture of the cosmetic product in the real space to the user in the virtual space, the augmented space, or the composite space, thereby enabling the user to try out the texture of the cosmetic product in the real space without going to a store, thereby improving user convenience.

[0024] [Content provider configuration] Next, the configuration of the content providing device 1 will be described. FIG. 2 is a block diagram showing an example of a functional configuration of the content providing device 1 according to the first embodiment. The content providing device 1 includes a communication unit 10 and a control unit 12.

[0025] The communication unit 10 communicates with the online test device 2 via a network. The communication unit 10 is controlled by the control unit 12, and transmits various information output from the control unit 12 to the online test device 2 and the feedback device 3. The communication unit 10 receives various information such as content transmitted from the online test device 2 and the feedback device 3, and outputs the received various information to the control unit 12.

[0026] The control unit 12 controls the processing of each unit of the content providing device 1, and exerts the functions of the content providing device 1. The control unit 12 may be configured with dedicated hardware, or may be configured with a general-purpose computer system. The computer system includes at least an arithmetic processing unit and a storage medium. For example, a processor such as a CPU (Central Processing Unit) may be applied as the arithmetic processing unit. A storage unit (not shown) and a flash memory (not shown) are used as the storage medium. For example, the arithmetic processing unit reads out a program stored in advance in the flash memory, and expands the read program in the storage unit. The arithmetic processing unit executes the program expanded in the storage unit to realize the functions of the control unit 12.

[0027] The control unit 12 includes a content providing unit 122. The content providing unit 122 provides the online test device 2 with the content of a simulated space, such as a virtual space, an extended space, or a composite space, managed by the content providing device 1.

[0028] [Online test equipment configuration] Next, the configuration of the online test device 2 will be described. FIG. 3 is a block diagram showing an example of a functional configuration of the online test device 2 according to the first embodiment. The online test device 2 includes a communication unit 20, a control unit 22, and a storage unit . The communication unit 20 communicates with the content providing device 1 and the feedback device 3 via the network. The communication unit 20 is controlled by the control unit 22, and transmits various information output from the control unit 22 to the content providing device 1 and the feedback device 3. The communication unit 20 receives various information transmitted from the content providing device 1 and the feedback device 3, and outputs the received various information to the control unit 22.

[0029] The control unit 22 controls the processing of each unit of the online test device 2, and exerts the functions of the online test device 2. The control unit 22 may be configured with dedicated hardware, or may be configured with a general-purpose computer system. The computer system includes at least an arithmetic processing unit and a storage medium. For example, a processor such as a CPU may be applied as the arithmetic processing unit. A storage unit (not shown) and a flash memory (not shown) are used as the storage medium. For example, the arithmetic processing unit reads out a program stored in advance in the flash memory, and expands the read program in the storage unit. The arithmetic processing unit executes the program expanded in the storage unit to realize the functions of the control unit 22.

[0030] The control unit 22 will now be described in detail. The control unit 22 includes a customized content providing unit 220 , an acquisition unit 221 , a user type confirming unit 222 , a sensory information providing unit 223 , and a learning unit 224 . The customized content providing unit 220 has a function of providing customized content in the virtual space, the extended space, or the composite space to the feedback device 3. The customized content providing unit 220 reads various information and programs related to the customized content from the storage unit 24, and provides the customized content in the virtual space, the extended space, or the composite space to the feedback device 3.

[0031] The acquiring unit 221 includes a user information acquiring unit 2211 and a selection information acquiring unit 2212 . The user information acquisition unit 2211 acquires user information from the feedback device 3. Specifically, the user information acquisition unit 2211 acquires a user ID and information on the type of the feedback device 3 from the feedback device 3. The user information acquisition unit 2211 stores the acquired user ID and information on the type of the feedback device 3 in association with the user type in the storage unit 24. The user type is information indicating whether each user is a paid user or a free user. A paid user is, for example, a user with whom a subscription contract has been concluded. The user information acquisition unit 2211 outputs the acquired user information to the user type confirmation unit 222.

[0032] The selection information acquisition unit 2212 acquires selection information from the feedback device 3. The selection information is information indicating the cosmetic product that the user desires to test for its tactile feel, selected from among the cosmetics available for tactile testing. Specifically, the selection information acquisition unit 2212 refers to the cosmetic product data stored in the storage unit 24 and transmits a list of cosmetics available for tactile testing to the feedback device 3. The selection information acquisition unit 2212 acquires selection information indicating the cosmetic product selected from the list of cosmetics available for tactile testing from the feedback device 3. The selection information acquisition unit 2212 outputs the acquired selection information to the user type confirmation unit 222.

[0033] When the user information is input from the user information acquisition unit 2211, the user type confirmation unit 222 refers to the user information stored in the storage unit 24 and determines whether the user type of the user with the user ID indicated by the user information is a paid user or a free user. When it is determined that the user with the user ID indicated by the user information is a paid user, the user type confirmation unit 222 outputs the user information, information on the type of the feedback device 3 associated with the user information, and the selection information input from the selection information acquisition unit 2212 to the sensory information provision unit 223.

[0034] On the other hand, if it is determined that the user with the user ID indicated in the user information is not a paying user, that is, if it is determined that the user is a free user, the user type confirmation unit 222 outputs the user information and the selection information input from the selection information acquisition unit 2212 to the sensory information provision unit 223.

[0035] The sensory information providing unit 223 refers to the cosmetic data stored in the storage unit 24 based on the user information input from the user type confirmation unit 222 and the selection information, and provides a free sample or a paid sample of the cosmetic indicated in the selection information to the user if available. In addition, the sensory information providing unit 223 causes the feedback device 3 to present a product advertisement for the cosmetic indicated in the selection information.

[0036] Furthermore, when information on the type of the feedback device 3 is input from the user type confirmation unit 222, the sensory information providing unit 223 acquires, based on the information on the type of the feedback device 3 and the selection information, sensory data of the cosmetic product indicated by the selection information, which corresponds to the type of the feedback device 3, from the storage unit 24. The sensory information providing unit 223 transmits the acquired sensory data to the feedback device 3.

[0037] The learning unit 224 performs machine learning using teacher data in which analytical data is input and sensory data is output, and generates a regression model as a learning result. The learning unit 224 has a function of generating a regression model as a trained model. The regression model according to this embodiment is a model in which analytical data and sensory data are associated with each other.

[0038] The learning unit 224 generates a regression model by, for example, statistical analysis. Specifically, the learning unit 224 generates the regression model based on the analysis data and the sensory data stored in the storage unit 24. The learning unit 224 stores the generated regression model in the storage unit 24.

[0039] The learning unit 224 may generate a regression model (trained model) by machine learning. Examples of machine learning techniques include SVR (support vector regression), random forest, and deep learning using a neural network. The learning unit 224 may generate a trained model by, for example, supervised learning. In supervised learning, a learning model is made to learn using a learning dataset. The dataset is a set of explanatory variables that are input during learning, and a target variable that indicates the correct answer of data that is output based on the input data.

[0040] In this embodiment, the explanatory variables are analysis data stored in the storage unit 24. The objective variables are sensory data. The learning unit 224 generates a trained model that has learned the correspondence between the analysis data and the sensory data by using the explanatory variables and the objective variables. The learning unit 224 stores the generated trained model in the storage unit 24.

[0041] The storage unit 24 stores various data and programs executed by the control unit 22. The storage unit 24 will be described in more detail. The content information storage unit 241 stores various information and programs relating to customized content.

[0042] The device information storage unit 242 stores the device information. The device information will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of device information according to the first embodiment. The device information is information in which identification information ("DID") for identifying a feedback device is associated with a "type of feedback device" and a "rank." The "type of feedback device" is information that indicates the device type of the feedback device 3. The "rank" is attribute information that is pre-ranked for each feedback device based on the tactile feedback performance of the feedback device 3, the price of the feedback device, etc.

[0043] In the illustrated example, the device information includes a "DID" that is device identification information, a "feedback device type," and a "rank" that are associated with each other. In the first line of the device information, for example, the "DID" is "D0001", the "feedback device type" is "Glove A", and the "Rank" is "1". In the second line of the device information, for example, the "DID" is "D0002", the "feedback device type" is "Finger B", and the "Rank" is "2". In the third line of the device information, for example, the "DID" is "D0003", the "feedback device type" is "Ultrasound C", and the "Rank" is "1". In the fourth line of the device information, for example, the "DID" is "D0004", the "feedback device type" is "Film D", and the "Rank" is "3".

[0044] The user information storage unit 243 stores user information. The user information will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of user information according to the first embodiment. The user information is information in which an identification number (UID) for identifying a user, the user's name, the user's type, and the type of feedback device owned by the user are associated with each other.

[0045] For example, the data in the first row has a "UID" of "U0001", a "name" of "○○△△", a user "type" of "paid", and a "type of feedback device" of "D0001". For example, the data in the second row has a "UID" of "U0002", a "name" of "□□○○", a user "type" of "free", and a "type of feedback device" of "-". For example, the data in the third row has a "UID" of "U0003", a "name" of "△△○○", a user "type" of "paid", and a "type of feedback device" of "D0002". In the illustrated example, the user indicated by "UID" and "U0002" does not own a feedback device. Furthermore, "type" and "paid" represent a paid user, and "type" and "free" represent a free user.

[0046] Cosmetic data storage unit 244 stores cosmetic data. The cosmetic data will be described with reference to FIG. FIG. 6 is a diagram showing an example of cosmetic data according to the first embodiment. The cosmetic data is information that associates the identification information (SID) for identifying the cosmetic, the analysis data of the cosmetic, the availability of free samples, the availability of paid samples, and product advertisements. The analysis data is data that indicates the relationship between the viscosity and shear rate for each cosmetic.

[0047] For example, the data in the first line has an "SID" of "S0001", a "product type" of "serum A", an "analysis data" of "AAA.dat", a "blank" indicating that there are no "free samples", a "blank" indicating that there are no "paid samples", and an html file "aaa_k.html" as advertising data for "product advertisement". Also, for example, the data in the second line has an "SID" of "S0002", a "product type" of "liquid foundation B", an "analysis data" of "BBB.dat", a "blank" indicating that there are no "free samples", "〇" indicating that there are "paid samples", and an html file "bbb_k.html" as advertising data for "product advertisement". For example, the data in the third row has a "SID" of "S0003", a "product type" of "moisturizing cream C", "analysis data" of "CCC.dat", an "O" indicating that a "free sample" is available, a "blank" indicating that a "paid sample" is not available, and a "blank" indicating that there is no advertising data for "product advertisement".

[0048] The sensory data storage unit 245 stores the sensory data. The sensory data will be described with reference to FIG. FIG. 7 is a diagram illustrating an example of sensory data according to the first embodiment. The sensory data is information in which identification information (SID) for identifying a cosmetic product is associated with sensory data that represents the tactile sensation in the virtual space, the extended space, or the composite space for each feedback device. For example, the data in the first row has an "SID" of "S0001", sensory data for feedback device "D0001" is "sAAA1.dat", sensory data for feedback device "D0002" is "sAAA2.dat", sensory data for feedback device "D0003" is "sAAA3.dat", and sensory data for feedback device "D0004" is "sAAA4.dat". Also, for example, the data in the second row has an "SID" of "S0002", sensory data for feedback device "D0001" is "sBBB1.dat", sensory data for feedback device "D0002" is "sBBB2.dat", sensory data for feedback device "D0003" is "sBBB3.dat", and sensory data for feedback device "D0004" is "sBBB4.dat". For example, the data on the third line has a "SID" of "S0003", sensory data for feedback device "D0001" is "sCCC1.dat", sensory data for feedback device "D0002" is "sCCC2.dat", sensory data for feedback device "D0003" is "sCCC3.dat", and sensory data for feedback device "D0004" is "sCCC4.dat".

[0049] The sensory data storage unit 245 may store a conversion rule from analysis data to sensory data for each feedback device, instead of storing sensory data for each feedback device. In this case, the sensory information providing unit 223 may refer to the conversion rule for each feedback device stored in the sensory data storage unit 245, and generate sensory data by converting the analysis data for each cosmetic product.

[0050] The statistical information storage unit 246 stores the trained model and the regression model.

[0051] [Feedback device functional configuration] Next, the functional configuration of the feedback device 3 will be described. FIG. 8 is a diagram illustrating an example of a functional configuration of the feedback device 3 according to the first embodiment. The feedback device 3 includes a communication section 30, a control section 32, and a feedback section .

[0052] The communication unit 30 communicates with the online test device 2 via the network. The communication unit 30 is controlled by the control unit 32, and transmits various information output from the control unit 32 to the online test device 2. The communication unit 30 receives various information such as content transmitted from the online test device 2, and outputs the received various information to the control unit 32.

[0053] The feedback unit 34 is a feedback device that provides the user with feedback of the feel of the cosmetic product in real space in a simulated space such as a virtual space, an extended space, or a composite space. The feedback section 34 includes a detection section 35 and a drive section 36 . The detection unit 35 detects the proximity or approach of the user's fingers. For example, the detection unit 35 is a sensor such as a pressure sensor, a contact sensor, an infrared sensor, or a proximity sensor. The detection unit 35 detects, for example, the contact or approach of the user's fingers with an object such as a desk. When the detection unit 35 detects the user's fingers, it outputs a detection signal indicating that the contact or approach has been detected to the control unit 32.

[0054] The driving unit 36 ​​is a driving device that is driven under the control of the control unit 32. The driving unit 36 ​​is, for example, an actuator, an ultrasonic generator, etc. The driving unit 36 ​​is driven under the control of the control unit 32, and provides feedback to the user's fingers in the real space of the feel of the cosmetic product in a simulated space such as a virtual space, an extended space, or a composite space.

[0055] The control unit 32 controls the processing of each part of the feedback device 3 and performs the functions of the feedback device 3. The control unit 32 may be configured with dedicated hardware, or may be configured with a general-purpose computer system. The computer system includes at least an arithmetic processing unit and a storage medium. For example, a processor such as a CPU may be applied as the arithmetic processing unit. A storage unit (not shown) and a flash memory (not shown) are used as the storage medium. For example, the arithmetic processing unit reads out a program stored in advance in the flash memory and expands the read program in the storage unit. The arithmetic processing unit executes the program expanded in the storage unit to realize the functions of the control unit 32.

[0056] The control unit 32 includes a user information providing unit 321, a selection information selecting unit 322, a sensory information acquiring unit 323, and a drive control unit 324. The user information providing section 321 transmits information of the feedback device including the feedback section 34 and the user information to the online test device 2 .

[0057] The selection information selection unit 322 acquires a list of cosmetics that can be tested for their tactile sensation in a simulated space such as a virtual space, an extended space, or a composite space from the online test device 2. The selection information selection unit 322 presents the acquired list of cosmetics that can be tested for their tactile sensation to the user, and allows the user to select a cosmetic included in the list. Based on the user's selection of a cosmetic for which a tactile sensation is to be tested from the list of cosmetics that can be tested for their tactile sensation, the selection information selection unit 322 transmits selection information indicating the cosmetic selected from the list of cosmetics that can be tested for their tactile sensation to the online test device 2.

[0058] The sensory information acquisition unit 323 acquires the sensory data of the cosmetic product indicated by the selection information from the online test device 2. The sensory information acquisition unit 323 outputs the acquired sensory data to the drive control unit 324.

[0059] The drive control unit 324 drives the drive unit 36 ​​based on the detection signal of the detection unit 35. Specifically, the drive control unit 324 drives the drive unit 36 ​​in accordance with the sensory data input from the sensory information acquisition unit 323 based on the detection signal input from the detection unit 35.

Note that since the hardware configurations of the content providing device 1 and the feedback device are similar, illustrations and descriptions thereof will be omitted. FIG. 9 is a block diagram showing an example of a hardware configuration of the online test device 2 according to the first embodiment. The online test device 2 is configured to include a CPU 201, a drive unit 202, a storage medium 203, an input unit 204, an output unit 205, a ROM 206 (Read Only Memory), a RAM 207 (Random Access Memory), an auxiliary storage unit 208, and an interface unit 209.

[0061] The CPU 201, the drive unit 202, the input unit 204, the output unit 205, the ROM 206, the RAM 207, the auxiliary storage unit 208, and the interface unit 209 are connected to each other via a bus. The CPU 201 referred to here refers to a processor in general, and includes not only a device called a CPU in the narrow sense, but also, for example, a GPU, a DSP, etc. The CPU 201 referred to here is not limited to being realized by one processor, and may be realized by combining multiple processors of the same or different types.

[0062] The CPU 201 reads and executes programs stored in the auxiliary storage unit 208, ROM 206, and RAM 207, and also reads various data stored in the auxiliary storage unit 208, ROM 206, and RAM 207, and writes the various data to the auxiliary storage unit 208 and RAM 207, thereby controlling the online test device 2. The CPU 201 also reads various data stored in the storage medium 203 via the drive unit 202, and writes the various data to the storage medium 203. The storage medium 203 is a portable storage medium such as a magneto-optical disk, a flexible disk, or a flash memory, and stores various data. The drive unit 202 is a device that reads and writes data from and to a storage medium 203 such as an optical disk drive, a flexible disk drive, or a flash memory.

[0063] The input unit 204 is an input device such as a mouse, a keyboard, a touch panel, a channel button, a power button, a setting button, and an infrared receiving unit. The output unit 205 is an output device such as a display unit, a speaker, or a head mounted display (HMD). The ROM 206 and the RAM 207 store programs for operating each functional unit of the online test device 2 and various data.

[0064] The auxiliary storage unit 208 is a hard disk drive, a flash memory, or the like, and stores programs for operating each functional unit of the online test device 2 and various data. The interface unit 209 has a communication interface, and is connected to the network NW, the content providing device 1, and the feedback device 3 by wire or wirelessly.

[0065] For example, the control unit 22 in the functional configuration of the online test device 2 in FIG. 3 described above corresponds to the CPU 201 in FIG. 9, the communication unit 20 in FIG. 3 corresponds to the interface unit 209 in FIG. 9, and the memory unit 24 in FIG. 3 corresponds to the storage medium 203, ROM 206, RAM 207, auxiliary memory unit 208, etc. in FIG. 9.

[0066] Next, the analytical data and sensory data of the cosmetics will be described. FIG. 10 is a diagram illustrating an example of the relationship between viscosity and shear rate according to the first embodiment. The example shown in FIG. 10 is an example of analytical data on the texture of cosmetics such as lotions, milky lotions, serums, and creams, and shows the flow curve measurement results for four samples, Sample A, Sample B, Sample C, and Sample D, which have different water-soluble polymers. Here, Sample A, Sample B, Sample C, and Sample D were subjected to a shear rate of 10 1 s -1 The samples have similar viscosities in the vicinity.

[0067] In the illustrated example, the difference in shear-thinning property is shown depending on the type of sample. The shear-thinning property of each sample is highest in the order of sample A, followed by sample B, sample C, and sample D. Here, shear thinning property refers to the property that the viscosity decreases as the shear rate increases when shear fluidity is applied. Figure 11 shows the results of sensory evaluation of Sample A, Sample B, Sample C, and Sample D.

[0068] FIG. 11 is a diagram showing an example of the relationship between the sensory information and the sensory evaluation score according to the first embodiment. A water-soluble polymer with high shear-thinning properties, for example, sample A, exhibits high sensory evaluation scores in the sensory evaluation items of ease of crumbling, freshness, and lightness.

[0069] FIG. 12 is a diagram showing an example of the sensory evaluation score and viscosity according to the first embodiment. The illustrated example shows a shear rate of 10 -2 s -1 And, 10 3 s -1 1 shows an example of the correlation between the ratio of shear viscosities in the test piece and the evaluation scores of these sensations. The cosmetic samples used in the evaluation were subjected to a shear rate of 10 -2 s -1And, 10 3 s -1 This shows that there is a very high correlation between the ratio of shear viscosity in the sample and the sensory evaluation items of ease of crumbliness, freshness, and lightness.

[0070] Next, the external configuration of the feedback section 34 of the feedback device 3 will be described. FIG. 13 is a diagram showing an example of the external configuration of the feedback section 34 of the feedback device 3 according to the first embodiment. The feedback device 3 includes a terminal device as a control device and a feedback device. The feedback device corresponds to the feedback unit 34 described above. In the illustrated example, the feedback unit 34 is in the form of a film that is attached onto the display of the terminal device and is laminated on the display of the terminal device. In the feedback unit 34, a pressure sensor detects contact of a user's finger based on the contact of the user's finger with the film. In the feedback unit 34, an actuator built into the film is driven based on the detection signal, and the feedback unit 34 feeds back the texture of the cosmetic to the user's finger that is in contact with the film.

[0071] FIG. 14 is a diagram showing another example of the external configuration of the feedback section 34 of the feedback device 3 according to the first embodiment. The feedback unit 34 may be a wearable feedback device such as a ring-type feedback device worn on the user's finger or a feedback device worn on the tip of the user's finger, for example, on the top of a nail. In this case, the feedback unit 34 detects the contact of the user's finger with an object such as a desk. The feedback unit 34 drives an actuator built into the wearable feedback device based on the detection signal, and feeds back the tactile sensation of the cosmetic product to the user's finger wearing the wearable feedback device.

[0072] FIG. 15 is a diagram showing another example of the external configuration of the feedback section 34 of the feedback device 3 according to the first embodiment. The feedback unit 34 may be a glove-type wearable feedback device worn on the hand of the user. In this case, the feedback unit 34 detects the contact of the user's finger with an object such as a desk by a detection unit arranged on the pad side of the finger. Based on the detection signal, the feedback unit 34 drives a nail-side actuator that faces the detection unit on the pad side of the finger, and feeds back the tactile sensation of the cosmetic product to the user's finger wearing the wearable feedback device.

[0073] In addition, the feedback unit 34 may be a non-contact feedback device that includes a detection device that detects the movement of the user's fingers using an infrared sensor and generates ultrasonic waves based on the detection signal to provide tactile feedback to the user's fingers.

[0074] [Haptic feedback processing] Next, the tactile feedback process in the online test system will be described. FIG. 16 is a flowchart showing an example of a haptic feedback process in the online test system according to the first embodiment.

[0075] (Step S102) The online test device 2 acquires user information including at least the type of the feedback device 3 and the user ID from the feedback device 3. After that, the online test device 2 executes the process of step S104.

[0076] (Step S104) The online test device 2 judges whether the user is a paying user based on the user information stored in the user information storage unit 243 and the user information acquired from the feedback device 3. If the user is a paying user (YES in step S104), the online test device 2 executes the process of step S106. On the other hand, if the user is not a paying user, that is, if the user is a non-paying user (NO in step S104), the online test device 2 executes the process of step S120.

[0077] (Step S106) The online test device 2 identifies the type of feedback device 3 owned by the user based on the type of the feedback device 3 acquired from the feedback device 3. The online test device 2 also identifies the rank of the feedback device 3 owned by the user by referring to the device information stored in the device information storage unit 242. After that, the online test device 2 executes the process of step S108.

[0078] In step S106, when the type of the feedback device 3 is known, the online test device 2 does not need to identify the type of the feedback device 3. In this case, the online test device 2 may execute the process of step S108 after the process of step S104.

[0079] (Step S108) The online testing device 2 refers to the cosmetic data stored in the cosmetic data storage unit 244 and transmits a list of cosmetics available for tactile testing to the feedback device 3. The online testing device 2 acquires selection information indicating a cosmetic selected from the list of cosmetics available for tactile testing from the feedback device 3. After that, the online testing device 2 executes the process of step S110.

[0080] (Step S110) The online test apparatus 2 transmits sensory data corresponding to the feedback device 3 owned by the user, that is, sensory data of the cosmetic product indicated by the selection information, to the feedback device 3. After that, the feedback device 3 executes the process of step S112.

[0081] (Step S112) The feedback device 3 determines whether or not a detection signal is being output by the detection unit 35. If a detection signal is being output by the detection unit 35 (YES in step S112), the feedback device 3 executes the process of step S114. On the other hand, if a detection signal is not being output by the detection unit 35 (NO in step S112), the feedback device 3 executes the process of step S116.

[0082] (Step S114) The feedback device 3 drives the drive unit in accordance with the sensory data based on the output of the detection signal, and provides feedback of the tactile sensation of the cosmetic product to the user. After that, the feedback device 3 executes the process of step S112.

[0083] In step S114, the feedback device 3 may feed back the tactile sensation by combining video, audio, etc. For example, the feedback device 3 may play back, on a head-mounted display or the like, video and audio corresponding to an operation in which the user picks up a cosmetic product in a virtual space, opens a lid on the cosmetic product, touches the cosmetic product with a finger, or the like, and feed back to the user the tactile sensation of the cosmetic product corresponding to the operation.

[0084] (Step S116) The feedback device 3 determines whether or not there is a model of a higher rank than the feedback device 3 owned by the user based on the fact that the detection unit 35 has stopped outputting a detection signal. If there is a model of a higher rank than the feedback device 3 owned by the user (YES in step S116), the feedback device 3 executes the process of step S118. On the other hand, if there is no model of a higher rank than the feedback device 3 owned by the user, that is, if the feedback device 3 owned by the user is the feedback device with the highest rank (NO in step S116), the feedback device 3 ends the tactile feedback process in FIG.

[0085] (Step S118) The feedback device 3 generates and presents to the user a presentation image encouraging the user to purchase the higher-ranked feedback device 3. After that, the feedback device 3 ends the haptic feedback process in FIG.

[0086] (Step S120) The online test apparatus 2 refers to the cosmetic data stored in the cosmetic data storage unit 244 and transmits the product advertisement to the feedback device 3. After that, the feedback device 3 executes the process of step S122.

[0087] (Step S122) The feedback device 3 generates and presents to the user a presentation image encouraging the user to purchase the feedback device 3. After that, the feedback device 3 ends the haptic feedback process in FIG.

[0088] Thus, the online test system SYS (tactile feedback system) according to this embodiment comprises an acquisition unit (selection information acquisition unit 2212) that acquires physical property data of a product, a conversion unit (sensory information provision unit 223) that converts the physical property data into sensory data adapted to a device, and a feedback unit 34 that feeds back to the device the tactile feel of the product according to the sensory data.

[0089] In this way, the online test system SYS according to the present embodiment can provide feedback of the feel of the product to the user, which allows the user to try the feel of the product at any location without going to a store, thereby improving user convenience.

[0090] In addition, the online test system SYS according to this embodiment includes an acquisition unit (selection information acquisition unit 2212) that acquires analytical data of the viscosity shear rate of the cosmetic in real space, an identification unit (user type confirmation unit 222) that identifies the type of device owned by the user, a conversion unit (sensory information provision unit 223) that converts the analytical data into sensory data that represents the feel of the cosmetic in the virtual space, the augmented space, or the composite space and is adapted to the device identified by the identification unit (user type confirmation unit 222), and a feedback unit 34 that feeds back to the device the feel of the cosmetic according to the sensory data.

[0091] In this way, the online test system SYS according to this embodiment can provide feedback of the texture of the cosmetic product in the real space to the user in the virtual space, the augmented space, or the composite space, thereby enabling the user to try out the texture of the cosmetic product in the real space without going to a store, thereby improving user convenience.

[0092] The online test system SYS further includes a presentation unit (selection information acquisition unit 2212) that presents a device purchase guide to a user who does not own a device.

[0093] In this way, it is possible to inform users who do not own a feedback device that there is an opportunity to experience the tactile sensation of a cosmetic product.

[0094] Moreover, the online test system SYS further includes a presentation unit that presents the user with a purchase guide for a higher-level device when a higher-level device exists than the device owned by the user identified by the identification unit (user type confirmation unit 222).

[0095] In this way, the user can be informed that there is a feedback device that allows the user to feel the texture of the cosmetic product more specifically.

[0096] [Variations] A modification of the first embodiment will be described. FIG. 17 is a diagram showing an example of a functional configuration of an online test device 2 according to a modification of the first embodiment. Comparing the configuration of the online test device 2 according to the first embodiment with the configuration of the online test device 2 according to the modified example, the difference is that the control unit 32 of the online test device 2 according to the modified example is equipped with a recommendation unit 225. In the modified example, the differences from the first embodiment will be mainly described, and a description of the similar configuration will be omitted.

[0097] The online test device 2 according to the modified example includes a communication unit 20, a control unit 32, and a storage unit . The control unit 32 includes a customized content providing unit 220, an acquisition unit 221, a user type confirmation unit 222, a sensory information providing unit 223, a learning unit 224, and a recommendation unit 225. The acquisition unit 221 includes a user information acquisition unit 2211 and a selection information acquisition unit 2212.

[0098] The recommendation unit 225 extracts a texture similar to the cosmetic product having a texture preferred by the user. Specifically, the recommendation unit 225 refers to statistical information based on at least one of the selection information and the user's purchase history, and extracts the user's preferred texture. The recommendation unit 225 extracts cosmetics having a texture similar to the user's preferred texture from the cosmetic product data. The recommendation unit 225 transmits a product advertisement for the cosmetic product having the extracted texture similar to the feedback device 3, and causes it to be presented to the user.

[0099] The recommendation unit 225 may provide sensory data or analysis data of cosmetics that the user likes as preference information to a service company that provides cosmetic samples.

[0100] [Haptic feedback processing] Next, the tactile feedback process in the online test system will be described. FIG. 18 is a flowchart showing an example of a tactile feedback process in the online test system according to the modified example of the first embodiment.

[0101] (Step S202) The online test device 2 acquires user information including at least the type of the feedback device 3 and the user ID from the feedback device 3. After that, the online test device 2 executes the process of step S204.

[0102] (Step S204) The online test device 2 judges whether the user is a paying user based on the user information stored in the user information storage unit 243 and the user information acquired from the feedback device 3. If the user is a paying user (YES in step S204), the online test device 2 executes the process of step S206. On the other hand, if the user is not a paying user, that is, if the user is a non-paying user (NO in step S204), the online test device 2 executes the process of step S220.

[0103] (Step S206) The online test device 2 identifies the type of feedback device 3 owned by the user based on the type of the feedback device 3 acquired from the feedback device 3. The online test device 2 also identifies the rank of the feedback device 3 owned by the user by referring to the device information stored in the device information storage unit 242. After that, the online test device 2 executes the process of step S208.

[0104] (Step S208) The online testing device 2 refers to the cosmetic data stored in the cosmetic data storage unit 244 and transmits a list of cosmetics available for tactile testing to the feedback device 3. The online testing device 2 acquires selection information indicating a cosmetic selected from the list of cosmetics available for tactile testing from the feedback device 3. After that, the online testing device 2 executes the process of step S210.

[0105] (Step S210) The online test apparatus 2 transmits sensory data corresponding to the feedback device 3 owned by the user, that is, sensory data of the cosmetic product indicated by the selection information, to the feedback device 3. After that, the feedback device 3 executes the process of step S212.

[0106] (Step S212) The feedback device 3 determines whether or not a detection signal is being output by the detection unit 35. If a detection signal is being output by the detection unit 35 (YES in step S212), the feedback device 3 executes the process of step S214. On the other hand, if a detection signal is not being output by the detection unit 35 (NO in step S212), the feedback device 3 executes the process of step S216.

[0107] (Step S214) The feedback device 3 drives the drive unit in accordance with the sensory data based on the output of the detection signal, and provides feedback of the tactile sensation of the cosmetic product to the user. After that, the feedback device 3 executes the process of step S212.

[0108] (Step S216) The online test device 2 refers to statistical information based on at least one of the selection information and the user's purchase history to extract the user's preferred tactile sensation. After that, the online test device 2 executes the process of step S218.

[0109] (Step S218) The online test device 2 extracts cosmetics having a texture similar to the one preferred by the user from the cosmetics data. After that, the online test device 2 executes the process of step S219.

[0110] (Step S219) The online test device 2 transmits the extracted product advertisements for cosmetics having a similar texture to the feedback device 3, and causes the product advertisements to be presented to the user. The feedback device 3 presents to the user product advertisements for cosmetics that have a similar feel to the cosmetics that the user likes, and then ends the process in FIG.

[0111] (Step S220) The online test apparatus 2 refers to the cosmetic data stored in the cosmetic data storage unit 244 and transmits the product advertisement to the feedback device 3. After that, the feedback device 3 executes the process of step S222.

[0112] (Step S222) The feedback device 3 generates and presents to the user a presentation image encouraging the user to purchase the feedback device 3. After that, the feedback device 3 ends the haptic feedback process in FIG.

[0113] Thus, the online test system SYS (tactile feedback system) according to this embodiment comprises an acquisition unit (selection information acquisition unit 2212) that acquires physical property data of a product, a conversion unit (sensory information provision unit 223) that converts the physical property data into sensory data adapted to a device, and a feedback unit 34 that feeds back to the device the tactile feel of the product according to the sensory data.

[0114] In this way, the online test system SYS according to the present embodiment can provide feedback on the feel of the product to the user. Therefore, for example, the user can try the feel of the product at any place without going to a store, improving the convenience for the user. In addition, the user can try the feel of a product similar to the feel of the user's preference information, so that new products can be suggested to the user.

[0115] As described above, the online test system SYS according to this embodiment includes an acquisition unit (selection information acquisition unit 2212) that acquires analytical data of the viscosity shear rate of the cosmetic in real space, an identification unit (user type confirmation unit 222) that identifies the type of device owned by the user, a conversion unit (sensory information provision unit 223) that converts the analytical data into sensory data that represents the feel of the cosmetic in the virtual space, the augmented space, or the composite space and is adapted to the device identified by the identification unit (user type confirmation unit 222), and a feedback unit 34 that feeds back to the device the feel of the cosmetic according to the sensory data.

[0116] In this way, the online test system SYS according to this embodiment can provide feedback of the texture of the cosmetic product in the real space to the user in the virtual space, the augmented space, or the composite space, thereby enabling the user to try out the texture of the cosmetic product in the real space without going to a store, thereby improving user convenience.

[0117] The online test system SYS further includes a presentation unit (selection information acquisition unit 2212) that presents a device purchase guide to a user who does not own a device.

[0118] In this way, it is possible to inform users who do not own a feedback device that there is an opportunity to experience the tactile sensation of a cosmetic product.

[0119] Moreover, the online test system SYS further includes a presentation unit that presents the user with a purchase guide for a higher-level device when a higher-level device exists than the device owned by the user identified by the identification unit (user type confirmation unit 222).

[0120] In this way, the user can be informed that there is a feedback device that allows the user to feel the texture of the cosmetic product more specifically.

[0121] In addition, the online test system SYS further includes a presentation unit (recommendation unit 225) that presents to the user advertisements for cosmetics having a texture similar to the cosmetic having the user's preferred texture.

[0122] This makes it possible to present cosmetics that meet the user's preferences.

[0123] In addition, the online test system SYS further includes an output unit (recommendation unit 225) that outputs sensory data of a cosmetic product having a texture preferred by the user.

[0124] This makes it possible to provide preference information to companies that provide cosmetic samples.
