A cosmetic device according to an embodiment of the present disclosure comprises: a main body; a head module that is detachable from the main body; a control unit for recognizing the head module mounted to the main body; and a communication unit for transmitting information about the recognized head module to a mobile terminal. The control unit can control the operation of the head module mounted to the main body differently according to the information received from the mobile terminal.

A method, performed by a wearable device, of providing haptic feedback to a user is provided. The method includes obtaining profile data of the user, obtaining biometric data of the user by using one or more biosensors, calculating, based on the profile data and the biometric data of the user, a target contact pressure to be applied to a body of the user by one or more haptic actuators, measuring a current contact pressure applied to the body of the user by the one or more haptic actuators by using one or more pressure sensors, and adjusting the current contact pressure of the one or more haptic actuators based on the current contact pressure and the target contact pressure.

The following disclosure discusses systems and methods of detecting and analyzing cutaneous conditions. According to one embodiment, a 2D image of the cutaneous condition and a set of 3D point clouds associated with the 2D image are captured using an image capturing device. The 2D image and the set of 3D point clouds are sent to a computing device. The computing device generates a 3D surface according to the set of 3D point clouds. Subsequently, the computing device receives a depth map for the 2D image based upon the 3D surface from another computing device such that the depth map comprises depth data for each pixel of the 2D image. The cutaneous condition may then be measured and analyzed based upon the depth map using the computing device.

Facial skin analysis methods and systems for improving facial skin conditions using vehicle cameras of vehicles having onboard communication modules. Each vehicle is equipped to analyze the facial skin images over time periods and compare the images to determine skin conditions. Based on the facial skin conditions, a treatment recommendation can be transmitted to a seat occupant. Each vehicle is operatively connected to a facial skin analysis application in a data center. The facial skin analysis application includes a registration module which registers each vehicle. Additionally, a vehicle user may register with the facial skin analysis application to have his/her facial skin analyzed when travelling in any of the plurality of vehicles. The facial skin analysis application is operatively connected to a skin data AI analytics module and data lake and searches a plurality of databases for information related to the facial skin conditions to improve the treatment recommendation.

Optical property measurement using a sensor behind a display screen Examples of this application disclose a method for measuring optical properties of a target. The method comprises illuminating the target with an illumination area with a display screen in contact with the target, and analysing signals reflected from the target and transmitted back through the display screen to a sensor positioned behind the display screen, to determine the optical properties of the target.

A facial skin disorder (FSD) identification system is provided and includes a sliding rail arranged around a human facial epidermis, a carrier arranged on the sliding rail, at least one image capturing device arranged on the carrier, and a control circuit unit arranged on the carrier for the carrier to move on the sliding rail and the image capturing device to capture images of the human facial epidermis.

An arrangement and a computer program product are provided for determining body surface characteristics. An arrangement includes an acquisition unit configured to detect body surface features by Multiple Spatially Resolved Reflection Spectroscopy (MSRRS) in a wavelength range between about 300 nm and about 1500 nm; a data storage unit to interrogate data using the characteristics; and a user interface comprising an output unit, wherein the user interface is configured to interact with a user. Further, the arrangement includes a portable computing unit configured for: interacting with a user and for evaluating the features and for determining the characteristics based on the features; obtaining from the data storage unit features of treatment products and/or application instructions for non-therapeutic treatment of a body surface according to the characteristics; and instructing the output unit to output information on the treatment products and/or application instructions to a user.

Systems, methods, apparatuses, and computer program products for contact-free heart rate monitoring and/or measurement are provided. One method may include receiving video(s) that include visual frame(s) of individual s) performing exercises, detecting some exposed skin from the video(s), and performing motion compensation to generate color signals for the exposed skin to precisely align frames of the exposed skin. The method may also include generating the color signals by estimating a skin color for each frame by taking a spatial average over pixels of a cheek of the face(s) for R, G, and B channels, respectively, applying an operation to remove remaining motion traces from the frames such that the heart rate traces dominate, and extracting and/or outputting the heart rate of the individuals using a frequency estimator of the skin color signals.

A volumetric sampling apparatus for volatile compounds comprises a structure, such as a channel structure that forms a continuous curve between the inlet port and the outlet port. A gas flow induced in the structure urges volatile compounds collected via transdermal diffusion toward the outlet port, where the volatile compounds may be collected and analyzed by a gas composition analyzer coupled to the outlet port.

Embodiments relate to a non-invasive electronic device including at least one sensing unit capable of accurately monitoring a user's health condition for a long time such as a few weeks without malfunction while it is worn on the wearer's skin in a non-invasive manner and a method for fabricating the non-invasive electronic device. The non-invasive electronic device includes for example, a skin sensor device.
