Abstract: According to an aspect, there is provided a computer-implemented method for providing visual feedback to a user of a rotary shaver. The method comprises (i) receiving movement measurements representing movement of the rotary shaver during a shaving operation; (ii) processing the received movement measurements to determine a representation of a trajectory of movement of the rotary shaver during the shaving operation; (iii) processing the determined representation to project the representation onto a two-dimensional plane; (iv) generating a graphical user interface, GUI, the GUI including the projected representation and a graphical template comprising an annular target zone for a correct circular motion of the rotary shaver during the shaving operation; and (v) displaying the generated GUI using a display unit.

Abstract: According to an aspect, there is provided an apparatus for use with a treatment device for providing feedback to a user on a treatment operation performed on a body part of a subject, wherein the treatment device is configured to apply light pulses to skin of the body part to perform the treatment operation, wherein a light pulse applied to the skin treats an area of the skin.

Abstract: A computer-implemented method for estimating surface area and/or volume of a subject's body or body part. First, at least one image, including the subject's face, is obtained. The image is processed to determine facial image parameter(s) of the subject's face. The subject's characteristic(s) including age, weight, height, and/or gender—is/are also determined. A facial parametric model and the facial image parameters are used to determine facial shape parameters of the subject's face, where the facial parametric model relates specific values for facial image parameters to a respective 3D representation of a face having respective values for the facial shape parameters. A prediction model with the characteristic(s) and the facial shape parameters are used to predict a 3D representation of the subject's full body. The predicted 3D representation of the subject's full body is analyzed to estimate the surface area and/or volume of the subject's body or body part.

Abstract: A skin treatment system including a treatment device to treat a treatment region of a body. The skin treatment system includes a camera to capture at least one image of skin, the image having an imaging region, and to provide captured image data representing the captured image. The imaging region has a predefined spatial relationship with the treatment region. The skin treatment system further includes a storage facility for storing reference image data indicative of a reference image of the skin. The skin treatment system further includes an orientation estimation facility to determine which part of the reference image corresponds to the at least one captured image, using the captured image data and the reference image data, and to derive from a predetermined orientation of said corresponding part with respect to the reference image, an orientation indication indicative of an orientation of the treatment device with respect to the body.

Abstract: A skin treatment system (1) is provided comprising a treatment device (10) to treat a treatment region (TR) of a mammal body (B) by physically acting upon the body in said treatment region. The skin treatment system further comprises a camera (20) to capture at least one image of skin of the mammal body, said image having an imaging region (IR), and to provide captured image data (Id) representative of the at least one captured image. The imaging region (IR) has a predefined spatial relationship with the treatment region. The skin treatment system (1) further comprises a storage facility (30) for storing reference image data (Ir) indicative of a reference image of the skin of the mammal body (B).

Abstract: The invention relates generally to the treatment of skin using laser light, and more particularly to a non-invasive device and method for such treatment. During skin treatments, heating of the epidermis is undesired because it may cause discomfort for the person being treated, adverse skin reactions and unwanted changes in skin pigment. The invention provides a laser treatment beam having a first 22a and a second 22b beam region of non-zero light intensity disposed at a periphery of a transverse cross-section of the beam, and a third beam region 22c, arranged between the first 22a and the second 22b beam region, of lower light intensity than said non-zero light intensity. The treatment beam 22 exits the device 10 along its optical treatment axis 13.
