More specifically, the invention relates to AI skin analysis based on facial imaging, body composition analysis based on two-hand insertion and contact, an AI prescription and recommendation engine integrating the results of the two analyses, a vending device that automatically dispenses customized products (cosmetics, nutrition bars, vitamins, etc.) to the user based on the results, a multilingual metahuman avatar consultation function, an alignment bay and condensation suppression device for eliminating interference from water vapor, moisture, and fine particles, a narrow-space type imaging unit for privacy protection, and a convergence platform applicable across all industries in hospital, gym, spa, and hotel environments. Background Technology

[0002] Existing AI skin diagnosis solutions based on cosmetic stores or mobile apps suffer from problems such as significantly varying accuracy depending on lighting and angles, and low reproducibility during repeated measurements due to the lack of an alignment device to maintain a consistent position of the user's face. Additionally, in high-temperature and high-humidity environments such as gyms, saunas, locker rooms, and spas, lens condensation and camera performance degradation occur frequently, leading to reduced accuracy in skin analysis. Furthermore, in diverse climatic environments like Korea and Vietnam, differences in illumination and humidity cause an increase in error rates even with the same equipment.

[0003] Meanwhile, body composition devices used in fitness centers and hospitals are not only large and expensive to install, but they are also generally not integrated with face-based skin analysis systems. Consequently, there are virtually no solutions available that provide customized health and beauty prescriptions by comprehensively analyzing skin and body composition conditions. Furthermore, there is a lack of vending machine structures that seamlessly connect users to the purchase of nutritional supplements, bars, and protein products based on body composition results and lifestyle information.

[0004] In existing systems, the separation of skin analysis results and the product purchasing process leads to high customer churn, and the lack of multilingual consultation capabilities makes it difficult to provide sufficient explanations to foreign users. While privacy protection is critical in actual store and locker room operations, there is also an issue where solutions based on photographing users' bare faces lack structural considerations regarding this.

[0005] Therefore, a new system is required that integrates skin analysis and body composition analysis to operate stably even in high-temperature and high-humidity environments, and can implement multilingual avatar consultation and vending machine functions in a single device. The problem to be solved

[0006] [Purpose of the Invention]

[0007] The main objectives of the present invention are as follows.

[0008] First, it maximizes the accuracy and reproducibility of AI skin analysis by ensuring the fixed posture, distance, and angle of the face through alignment bays.

[0009] Second, by introducing a condensation suppression and thermal circulation structure, the camera lens and internal sensor are designed to operate stably even in high-temperature and high-humidity environments such as saunas, locker rooms, and after exercise.

[0010] Third, it provides a comprehensive AI health and skin scoring model that integrates skin and body composition results by simultaneously performing AI facial analysis and BIA body composition analysis on a single device.

[0011] Fourth, based on the results of the above integrated analysis, a system is implemented to automatically sell cosmetics, nutrition bars, vitamins, functional beverages, etc., according to the user's condition.

[0012] Fifth, by having multilingual metahuman avatars provide real-time shooting guides, result explanations, and product information, it offers the same level of consultation experience to customers using various languages, such as Korean, English, Vietnamese, and Chinese.

[0013] Sixth, the goal is to design a platform usable in various locations such as hospitals, dermatology clinics, gyms, hotels, golf courses, and airports, thereby establishing a convergence service ecosystem encompassing medical, beauty, and tourism.

[0014] Seventh, it integrates personal information protection, filming security, and financial payments (POS, QR, NFC, etc.), and provides a foundation that can be expanded into VR / metaverse, medical tourism, and international marriage counseling booths in the future. means of solving the problem

[0040] Examples

[0041] The invention will be explained in more detail below through embodiments. The following embodiments are merely examples to aid in understanding the invention and do not limit the technical scope of the invention.

[0042] Example 1: Improvement of face imaging precision using an alignment bay

[0043] The alignment bay is designed to ensure that the user's face is always captured from the same distance, angle, and height. The left and right side wall panels secure the user's head position from both sides, and the inner surface is treated with a matte coating to minimize optical reflection. The bottom chin support bar is positioned at a height where the user can lightly rest their chin, ensuring the shooting position is fixed without the need for strong force. The top integrated lighting panel maintains a color temperature in the 5500–6500K range, and the light output is automatically adjusted by an ambient light sensor. When the user positions their face inside the alignment bay, the camera generates a 3D Face Mesh to evaluate alignment accuracy, and if it falls below the standard, it indicates the direction for fine-tuning via LED guide lines. Additionally, an image stabilization algorithm is applied to eliminate minute shake during the moment of capture.

[0044] Example 2: High temperature and high humidity performance of the condensation suppression device

[0045] The heating film is positioned within a 2–3 cm area around the camera lens to maintain a temperature in the 35–40°C range, thereby preventing moisture condensation on the lens surface. A triple-sealing structure is formed on the top and sides to block external water vapor from entering directly, and internal heat and moisture are forcibly expelled through air circulation ducts. A condensation detection sensor detects minute moisture concentrations, and if the threshold is exceeded, the AI ​​automatically adjusts the heating intensity and fan speed. This allows the device to operate normally even in environments with relative humidity exceeding 90%.

[0046] Example 3: AI-based face analysis function

[0047] When a user's face is captured, skin tone deviation, wrinkle depth and direction, pore size and density, keratin distribution, sebum volume estimation, moisture volume estimation, erythema, pigmentation, skin elasticity, and sagging indices are extracted. Additionally, estimated indices for basal metabolism and skin regeneration capacity can be calculated based on the facial image.

[0048] Example 4: Body Composition (BIA) Measurement Function

[0049] When the user inserts both hands into the lower insertion port, a low-voltage alternating current is injected through the palm contact electrodes and finger electrodes, and electrical impedance is measured. Through this, body water content (TBW), upper body core muscle mass, body fat percentage, estimation of basal metabolic rate, stress index based on electrodermal analysis (EDA), and estimated peripheral temperature and blood flow indices are calculated. As health indicators closely related to skin condition, these provide meaningful information during integrated analysis.

[0050] Example 5: Calculation of Integrated Skin and Body Composition AI Index

[0051] In this invention, skin and body composition data are integrated into a single AI model to calculate a Health-Derma Score. For example, if skin condition is good but the body fat percentage is 30% or higher, low water retention capacity is assessed as having a high risk of increased sensitivity in the future; if muscle mass is insufficient, the risk of skin tone deterioration due to reduced facial blood flow is reflected. Additionally, if dehydration and a deficiency in specific vitamins are estimated, a high recommendation index for nutrition bars or supplements is calculated.

[0052] Example 6: Multilingual Avatar Consultation Function

[0053] The present invention provides a metahuman-based multilingual avatar to enhance user trust. The avatar performs functions such as providing guidance on posture, facial expressions, and lighting before shooting, guiding stability during shooting, summarizing results after shooting, explaining recommended cosmetics and nutritional bars, and providing information on nearby hospitals, dermatology clinics, gyms, and hotels. Languages ​​such as Korean, English, Vietnamese, Thai, and Chinese are supported, and reinforcement learning can be applied to perform highly reliable communication by learning user purchasing patterns and response data.

[0054] Example 7: Cosmetics automatic vending function

[0055] The recommendation algorithm combines and recommends products such as Vitamin C ampoules when skin tone deteriorates, moisturizing creams when dead skin cells increase, oil-control serums when sebum and body fat increase, and hypoallergenic soothing lines when sensitivity increases. The control unit checks the inventory of the selected product and drives the motor of the corresponding cell to move the product to the dispensing port. During the dispensing process, a sensor detects whether the product has passed through; if the product fails to be dispensed, it records an error and guides the user to the retry or refund procedure.

[0056] Example 8: Nutrition Bar / Protein Bar Automatic Vending Function

[0057] The nutrition bar storage unit includes a temperature control function in the range of 18–25°C or 5–15°C to maintain the quality of products such as protein bars and collagen jellies. By comprehensively analyzing skin and health risks resulting from protein deficiency, vitamin B deficiency, excessive carbohydrate intake, and excessive fat intake, different recommended ratios for energy bars, protein bars, and vitamin bars can be set.

[0058] Example 9: Installation Case in a High Temperature and High Humidity Region

[0059] The device of the present invention can be installed in areas without specialized dermatology clinics, such as rural Vietnam, rural regions of Korea, and mountainous areas. In such cases, it can identify early signs of abnormalities, such as seborrheic dermatitis, psoriasis, or the risk of acne exacerbation, through basic skin condition checks and body composition analysis, and output a message recommending a visit to a nearby public health center or hospital if necessary. Such operation contributes to the improvement of public health and access to medical care.

[0060] Example 10: Linkage of Tourism, Medical Tourism, and International Marriage Services

[0061] The device can be integrated with medical tourism platforms (such as VR MEDI TOUR & HOME) via the cloud. Analysis results and purchase history are automatically transmitted to the company's AI account, enabling integrated customer management between Korea and Vietnam, and allowing health and skin condition information to be used as reference material at medical tourism or international marriage consultation booths.
