The present invention relates to a device for skin parameter measurement, comprising a housing structure () defining an interior cavity () and a first opening () at a skin contact end () of the interior cavity (), a movable part () connected to the housing structure () via an elastic connecting arrangement (), the movable part () being movable with respect to the housing structure () and configured to protrude the skin contact end () through the first opening () of the housing structure when no external force is applied to move the movable part () with respect to the housing structure, the movable part () further comprising a second opening (), an optical sensing unit () for performing measurement of a first skin parameter when the device is in contact with a skin surface, the optical sensing unit being provided within the interior cavity of the housing structure and comprising an illuminating unit (A) for illuminating the skin surface by emitting light through the second opening () of the movable part and an imaging unit (B) for receiving light reflected by the illuminated skin surface, and an electrical sensing unit () for measuring a second skin parameter, wherein the electrical sensing unit () is arranged at a front end section of the movable part () defining the second opening ().

Device, system and method for measurement of a skin parameter

The present invention relates to an accessory device () for an image-capturing device () for capturing a skin image of a subject's skin comprising a tubular member () having a first opening () at its first end () configured to surround a light source () and an image sensor () included in the image-capturing device () and a second opening () at its second end () configured to surround a skin portion () and two mirrors () arranged within the tubular number () at its second end (), wherein a first mirror () is arranged to retied light () emitted by the light source () towards the skin portion () and a second mirror () is arranged to reflect light () reflected from the skin portion () towards the image sensor (). The accessory device can be coupled to an image-capturing device to acquire an image of a skin portion, which is evaluated to determine a skin parameter, such as skin gloss.

Accessory device and imaging device

There is provided a method of providing feedback regarding motion of a rotary shaver performed by a user, the method comprising the steps of receiving, during at least one time interval, at least one motion type determined for the motion of the rotary shaver performed by the user, wherein the motion type is selected from a set of predefined motion types that comprises small rotational motion and one or more other predefined motion types; determining a degree of occurrence in the time interval of each of the motion types in the set of time interval; determining from the determined degree of occurrence of each of the motion types in the set of predefined motion types which motion type has a highest degree of occurrence in the time interval; and providing feedback to the user to increase a degree of occurrence of small rotational motion of the rotary shaver if the determined motion type having the highest degree of occurrence is one of the other predefined motion types.
