The reason why under-eye sagging has changed is determined. A method according to an embodiment of the present invention includes acquiring information on a three-dimensional shape of an under-eye area of a subject when the subject is in a vertical position before a change in under-eye sagging of the subject and information on a three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position after the change in the under-eye sagging; and determining a reason for the change in the under-eye sagging, based on a volume difference between the three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position before the change in the under-eye sagging and the three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position after the change in the under-eye sagging.

The present invention provides a novel system of hardware designed to capture and process in real time clinical observations of patient responses and reactions in different clinical and patient settings and situations, comprising: a patient biometric data recording system in a clinical office, a mobile real time episode or event data recording device system or a wearable device recording system.

A sensor is provided for sensing layer removal from a surface. A head has an abrasive portion for contacting the surface and a conducting portion inside the head. This device has a sensor design which provides self-generation of a sensor signal with no power supply to the device head. This simplifies the design of the sensor head, and means it can have a design which is easy to clean with no parts which are easily damaged. In one set of examples, the device is a skin treatment device.

A plurality of user actions corresponding to the image information is analyzed, where a plurality of consecutive image information of the image information corresponds to one of the user actions. The image information is classified to the skin care behaviours according to the user action corresponding to each of the image information. Each of the skin care behaviours corresponds to a plurality of the user actions. A duration of each of the skin care behaviours is calculated according to the image capturing time of the image information classified to each of the skin care behaviours. An electronic device using the skin care evaluation method is also provided.

Disclosed is a wearable device comprising: an impedance sensor for measuring an impedance signal inside a user's body; and a controller for determining the number of meals for a predetermined period and the glycemic index corresponding to each meal using the measured impedance signal and providing the user's eating habit information on the basis of the number of meals and the glycemic index.

Apparatus and methods are disclosed for multi-spectral imaging of tissue to obtain information about the distribution of fluorophores and chromophores in the tissue. Using specific spectral bands for illumination and specific spectral bands for detection, the signal-to-noise ratio and information related to the distribution of specific fluorophores is enhanced as compared to UV photography, which uses a single RGB image. Furthermore, the chromophore distribution information derived from the multi-spectral absorption images can be used to correct the fluorescence measurements. The combined fluorescence, absorption, and broadband reflectance data can be analyzed for disease diagnosis and skin feature detection.

A tactile sensor, computer readable medium, methods of using and manufacturing the tactile sensor, and methods and apparatuses for processing the information generated by the tactile sensor. The tactile sensor includes a planar optical waveguide comprised of a flexible and transparent layer, a light configured to direct light into the optical waveguide; a light sensor or an imager facing the optical waveguide and configured to generate signals from light scattered out of the optical waveguide; and a controller which may be configured to generate an image of the object and characteristics of the object. The waveguide may be configured so that some of the light directed into the optical waveguide is scattered out of the waveguide if the waveguide is deformed by being pressed against the object. A finite element and a neural network are used to estimate mechanical characteristics of the objects.

An example system, for analyzing biometric data, is disclosed. The system includes a sensor unit to measure biometric data of a user.
