There is provided an information processing apparatus including: an acquisition unit that acquires measurement results of a user's skin state; and a presentation unit that displays a chart image configured by arranging a plurality of areas, to which a plurality of items of the measurement results are assigned, having a same shape and a same size in respective directions with a predetermined position used as the center and arranging score images representing scores of the items inside each of the areas so as to have sizes corresponding to the scores and to expand from the predetermined position.

A mobile terminal includes: a wireless communication unit; a display; and a controller configured to receive location information from an auxiliary device via the wireless communication unit, wherein the location information includes curvature information of a part of a face of a user that is in contact with the auxiliary device and movement information of the auxiliary device relative to the user; recognize a part of the face based on the location information; and cause the display to display the recognized part of the face in real time.

A control method for controlling a skin analysis device is a control method for controlling a skin analysis device including a camera for obtaining a face image of a subject, a display for displaying the face image of the subject, and a computer, wherein the control method causes the computer of the skin analysis device to execute: obtaining the face image of the subject; determining a target extraction criterion for each of a plurality of skin areas of the face image based on a position on the face image; and extracting a target that satisfies the determined extraction criterion from the face image; and displaying the extracted target on the display of the skin analysis device.

Disclosed is a polarization sensitive optical coherence tomography apparatus and control method thereof. According to the polarization sensitive optical coherence tomography apparatus and control method thereof of the present invention, the local phase delay value of each layer of a multiple of layers using Jones matrix for a birefringent material having the multiple of layers where each layers optical axis is random based on a polarized signal detected in an optical detector may be calculated. According to the present invention, a skin aging level can be accurately examined by obtaining an accurate accumulated phase delay value for a multiple of layers of birefringent material having a random optical axis.

According to an aspect of some embodiments of the present invention there is provided a method of dynamically adapting a facial treatment based on a current facial skin profile, comprising: using at least one sensor for measuring at least one current value of at least one variable skin characteristic of facial skin of a patient; acquiring at least one personal skin characteristic of facial skin of the patient; calculating a current facial skin status of the patient according to the at least one personal skin characteristic and the at least one current value; determining instructions to operate a treatment applicator according to the current facial skin status; and instructing the treatment applicator according to the instructions.

A non-invasive method for estimation of strain profile and dynamic evolution of the strain at a location interposed inside a block of soft material, includes forming a tracer grid consisting of microscopic lines or regularly spaced microscopic dots on a single plane buried inside the soft block; preparation of a deformable object embedded with the tracer grid in three primary steps: i. preparing a block of crosslinked material by crosslinking a first predetermined quantity of a pre-polymer solution containing a monomer, a crosslinking agent, and an initiator and promoter all mixed in a solvent at a known stoichiometric weight ratio; ii. transferring a grid comprising of lines or dots onto the face by direct writing or transferring from an easy release surface; and iii. crosslinking a second predetermined quantity of the same pre-polymer solution on the gel surface, such that this second crosslinked material gets welded to the first one.
