An application control device according to an embodiment of the present invention has an acquisition unit that acquires image data of a skin; a division unit that divides the image data into a plurality of segments each smaller than or equal to 200 μm; and a calculation unit that calculates, from a value of one or a plurality of segments of the image data, an application amount of a cosmetic material to be applied to each portion of the skin.

The present invention relates to a cosmetic ink application device which functions by producing a region as an alignment marker on human skin and detecting the region to align an applicator with the skin, and a method thereof. A cosmetic ink application device according to the present invention comprises: a light source for irradiating human skin with ultraviolet light; an optical sensor for detecting intensities of fluorescence in a ultraviolet range and/or a visible light range emitted from the skin in response to the irradiation of the ultraviolet light; an applicator for applying a cosmetic ink to the skin; a head portion for holding the light source, the optical sensor, and the applicator; and a controller, wherein the controller defines a region on the skin, which emits fluorescence having an intensity different from fluorescence emitted from other regions of the skin when irradiated with the ultraviolet light, as a marker region, wherein the controller determines a position of the ink application based on the marker region, and wherein the controller causes the applicator to apply the ink on a predetermined portion of the skin.

A voice recognition based smart mirror device includes: a plurality of arms rotatably connected to each other; and a mirror unit rotatably mounted to one of the plurality of arms. The mirror unit includes: a body part; a joint part through which the body part is pivotably connected to the one of the plurality of arms; a mirror part rotatably mounted to the body part; a display module part mounted on a front surface of the body part to output an image, the display module part serving to sense a touch signal of a user; a recognition part for detecting a voice signal of the user; and a controller configured to control the display module part in accordance with the voice signal or the touch signal.

A beauty product device is disclosed which includes a variety of sensors for sensing the way in which a user is operating the device. The sensor data can be processed and compared with pre-stored data representative of a desired style and feedback messages generated and provided back to the user to help them achieve the style they wish to achieve based on the comparison.

Systems and methods for formulating a personalized skincare product for a user. Data inputs reflecting dermal information of the user (e.g., hydration level measurements, oil level measurements, and a photograph of the user's skin reflecting a set of skin concerns) are collected by a computing device and used to determine a set of normalized scores. A skin health data set is generated based on the normalized scores and stored in memory. A skin health metric is determined based on the skin health data set and is stored in memory. The computing device determines, using a machine learning framework, one or more first skincare product formulations based on the user skin health data set. The formulation(s) can be used to manufacture one or more customized skincare products for the user and can be iteratively refined over time, e.g., by collecting additional data from the user over time.

Systems, devices, and methods for in situ diagnostic assessment and formula dispensing are described. A diagnostic formula applicator can include a fluid dispensing assembly coupled with a comb having a plurality of tines. A tine of the plurality of tines can be configured to dispense a fluid formula to a region of a biological surface via at least one fluid conduit. The diagnostic formula applicator can include hair diagnostic circuitry operably coupled to the fluid dispensing assembly. The diagnostic circuitry can be configured to actuate the fluid dispensing assembly to deliver the fluid formula via the at least one fluid conduit, responsive to determining a user-specific hair cosmetic aspect from hair and scalp sensor information.

Provided are a nail measuring device, system, and method for customized nail products. The device comprises a nail gauge attached to a nail of a user to measure a three-dimensional (3D) shape data figure including a width and curvature value of the nail through photography. The device may take the form of measuring stickers which are attached to fingernails. An image is taken of fingernail having the sticker and the image is processed by the system to determine a size and shape of the nail.

Systems, devices, and methods for generating, sharing, and presenting augmented reality cosmetic design filters. One or more non-transitory computer memory devices can store computer-readable instructions that, when executed by computing circuitry, cause the computing circuitry to perform operations for generating augmented reality cosmetic design filters. The operations can include defining a baseline description of a biological surface using one or more radiation sensors, the radiation sensors being electronically coupled with the computing circuitry. The operations can include identifying an application of a cosmetic formulation to the biological surface using one or more of the radiation sensors. The operations can include generating a trace describing the application in reference to the baseline description. The operations can also include outputting the trace.

Glasses are used to determine a color of each position of a face of a user by a computer system based on first image data (with-glasses face image) obtained by capturing an image of the user wearing the glasses, and second image data (no-glasses face image) obtained by capturing an image of the user without the glasses. The glasses include a position determination marker at a predetermined position and has a predetermined color (color pattern) at a predetermined position. The computer system determines the color of each position of the face of the user based on the first image data and the second image data using the marker and the color.

A user-customized skin diagnosis system includes: a portable skin condition measurement device for photographing a face of a user in a contactless manner; and a skin analysis device that receives an image of the user's face photographed from the portable skin condition measurement device, analyzes the received image for at least one skin analysis item based on preset image processing and deep learning, and generates and displays skin diagnosis information and customized recommendation information according to the analyzed result.
