In some embodiments, the skin care formula is a moistunzer, a toner, an acne treatment formula, a wrinkle or fine line treatment formula, or a cosmetic. As the applicator surface, illustrated here as a roller ball 110, moves or rolls, formula F from the reservoir 130 is applied to a surface. In some embodiments, the applicator 100 includes any number of formula reservoirs.

In some embodiments, the applicator 100 further includes a piston 145 configured to push the formula F towards the roller ball 110 as the formula is applied. In some embodiments, the piston 145 is directed or controlled by circuitry on a dispensing device or on the applicator 100 itself to push the formula F towards the applicator surface at a defined rate to control the flow rate of the formula F onto the surface of the roller ball 110.

In some embodiments, the applicator 100 includes an applicator processor 140. In some embodiments, applicator processor 140 performs functions relating to application of treatments. In some embodiments, the applicator processor 140 also performs functions relating to obtaining and storing information relating to skin conditions and treatments, and tracking progress of treatments over time.

Regarding functions relating to treatments, in some embodiments the applicator processor 140 is configured to direct or control the piston 145 to push the formula F towards the applicator surface 110 to the formula to the skin, to apply other treatments such as light treatments, or to control other aspects of the applicator 100.

In some embodiments, the skin condition sensor module includes a skin hydration sensor, a skin elasticity sensor, or a combination thereof. A skin elasticity sensor may take the form of a probe device configured to measure mechanical and viscoelastic properties of skin, such as by applying suction to the skin and measuring resistance of the skin to that suction, or through the use of tonometry. A skin hydration sensor may include, e.g., a capacitance sensor or conductance sensor. In some embodiments, the sensor module 135 includes a position sensor module configured to obtain position sensor data for calculating a position of the applicator 100 on the skin. In some embodiments, the position sensor module includes a two-dimensional (2D) or three-dimensional (3D) camera module, a proximity' sensor, a gyroscope, an accelerometer, or a combination thereof. In some embodiments, the camera module includes one or more cameras configured to take one or more 2D or 3D images (i.e., still images or video) of the skin as the user moves the applicator over the skin. In some embodiments, the camera module includes a microscope camera to capture magnified images of the skin area of interest. Capture of images may be aided by illumination provided by one or more light sources, such as light sources positioned on the applicator. Such images may be captured by the camera in, e.g., the visible, infrared, or ultraviolet spectrum, or a combination thereof. Images captured by the camera may be used to calculate the position of the applicator on the skin, such as by comparing captured images with known skin landmarks. Alternatively, position can be calculated based on images captured by one or more cameras positioned at a distance from the applicator, such that the images capture both the applicator itself and the part of the body on which the applicator is located. Other sensors such as accelerometers also may be used to calculate velocity of the applicator across the surface of the skin, orientation of the applicator relative to the skin surface, or other information.

In some embodiments, the applicator 100 is configured to administer radiation treatment via one or more radiating elements 125A, 125B, 125C.

In some examples, the connected device 300 is assumed to be a smartphone, such as an Apple iPhone.

The communication device 300 is capable of performing wireless communication with the base device 300 by way of a wireless communication interface circuitry on the base device 200 or the applicator 100. However, communication device 300 is also capable of having a wired connection to the base device 200 by way of a USB interface. Additionally, the applicator 100 and the base device 200 may communicate with each other and the communication device 300 through an internet connection via an 802. 1 1 wireless connection to a wireless internet access point, or a physical connection to the internet access point, such as through an Ethernet interface. Each connected communication device 300 is capable of performing wireless communication with other devices, such as through a Bluetooth connection or other wireless means as well.

The connected communication device 300 is configured to receive information from a user for use in generating a treatment plan, including one or more treatments, that may be used by the base device 200 to dispense one or more formulas, one or more light treatments, one or more radiation treatments, or a combination thereof.

In some embodiments, the communication device 300 has a related application on it, configured to aid a user in dispensing a formula and/or cleaning an applicator 100.

In some embodiments, communication device 300 includes one or more cameras and a user interface such as a touchscreen display, which may present to interactive functionality such as depictions of changes in skin conditions over time, tutorial videos or animations, or other elements.

In some embodiments, communication device 300 executes a client application and an image capture/scanning engine configured to capture and process digital images (e.g., color images, infrared images, depth images, etc.) or other data obtain from, e.g.. one or more cameras on the applicator 100. In some embodiments, the digital images or scans are processed by communication device 300 and/or transmitted to a remote computer system for processing, e.g., in a 2D or 3D skin surface model engine that maps skin features, skin condition information, or other information in the model. In some embodiments, captured image data is transmitted to a position tracking engine for determining the position of the applicator 100 relative to a body surface. In some embodiments, the position tracking engine maintains awareness of where the target body surface is and where the applicator is in a 3D space.

In some embodiments, digital 3D models described herein are generated based on sensor data obtained from sensor modules 135. In such embodiments, the digital 3D models are generated by the communication device 300 or some other computing device, such as a remote cloud computing system, or a combination thereof. In some embodiments, the digital 3D models include 3D topology and texture information, which can be used for reproducing an accurate representation of a body surface, such as facial structure and skin features. In some embodiments, communication device 300 prepares information for transmission to, or receives and interprets information from other devices or systems, such as a remote computer system or base device 200. Such information may include captured digital images, scans, or video; device settings; custom care routines specifying, e.g., formula application information or light treatment information; user preferences; usage data, user identifiers, device identifiers, or the like.

In some embodiments, the system 2000 is configured to apply one or more algorithms to a photo or video of a user to detect one or more skin conditions. In some embodiments, the system 2000 uses deep learning algorithms that employ artificial neural networks to identify combinations of image features in input images of skin and classify those input images as including skin conditions such as acne, hyperpigmentation, rosacea, wrinkles, fine lines, wounds, dark circles, or other conditions. Such algorithms may further take into account other information besides images to identify a condition, such as user questionnaire information. In some embodiments, the deep learning algorithms are trained using a supervised learning approach. In some embodiments, the communication device 300 communicates the detected condition to a user of the system and proposes one or more treatments to be applied by the applicator 100.

In some embodiments, the system 2000 may further obtain environmental condition information with one or more environmental sensors or from some other source, such as a server computer. In some embodiments, the environmental conditions may include temperature, humidity, ultraviolet (UV) radiation levels, pollution levels, and the like. In some embodiments, the application can gather environmental data from other sources such as weather sendees. In some embodiments, the application can further recommend a formula, comprised of one or more skin ingredients, to the user based on the detected skin feature and/or environmental conditions.

In some embodiments, the user can set up a user profde on the application of the communication device 300. In some embodiments, setting up the user profile includes answering a user questionnaire. In some embodiments, the user questionnaire gives the user a senes of inputs including past skin treatment, past use of the applicator, desired skin quality, or skin concern. In some embodiments, a client application running on the communication device 300 can solicit feedback from the user regarding their favorite or most effective formulation to help improve the algorithm.

In an embodiment, a care routine engine performs processing of data such as identifying changes in skin condition or generating or adjusting a care routine, such as making adjustments to treatment parameters or recommending new products. The care routine engine may be implemented on the communication device 300 or on some other device or system, such as a server in a cloud computing environment. A care routine may include, for example, programmatic care routine instructions for applying treatments, collecting data (e.g., image data, depth data, usage data, or other data), or performing other functions according to techniques described herein. In an embodiment, the care routine engine generates care routine information based on user information from a user profile data store, a product data store, or some other source or combination of sources. The care routine engine may employ machine learning or artificial intelligence techniques (e.g., template matching, feature extraction and matching, classification, artificial neural networks, deep learning architectures, genetic algorithms, or the like). For example, to identify changes in skin condition or generate or update treatment parameters, in the care routine engine may analyze (e.g., using computer vision and/or machine learning techniques described herein) digital scans to measure or map wrinkles, pigmentation, skin texture, etc., of the user’s skin in a single image or a series of images captured over time. In such a scenario, the care routine engine may use such information to recommend, generate or modify a particular care routine that suits the particular features of the user’s skin.

In addition to the technical benefits of described embodiments that are described elsewhere herein, numerous other technical benefits are achieved in some embodiments. For example, the system allows some aspects of the process to be conducted independently by personal care devices or client computing devices, while moving other processing burdens to a remote computer system (which may be a relatively high-powered and reliable computing system), thus improving performance and preserving battery life for functionality provided by personal care devices or client computing devices. In general, the word "engine." as used herein, refers to logic embodied in hardware or software instructions written in a programming language, such as C, C++, COBOL, JAVA™, PHP, Perl, HTML, CSS, JavaScript, VBScript, ASPX, Microsoft .NET™, and/or the like. An engine may be compiled into executable programs or written in interpreted programming languages. Software engines may be callable from other engines or from themselves. Generally, the engines described herein refer to logical modules that can be merged with other engines or divided into sub-engines. The engines can be stored in any type of computer-readable medium or computer storage device and be stored on and executed by one or more general purpose computers, thus creating a special purpose computer configured to provide the engine or the functionality thereof.

In block 910, the system obtains stored information including treatment characteristics and skin condition information cross-referenced with the calculated position of an applicator that applies the treatment(s) at that position.

In block 920, the system generates a visualization, such as a time lapse animation, of changes in skin condition based on the stored information. This can help show users the progress of skin treatments and suggest ways that treatments may be adjusted to achieve better results. Optionally, the skin condition information is compared with a baseline condition of the skin, such as a past condition of the skin, and an average condition over time, or a desired skin condition. In some embodiments, the baseline condition is stored and/or communicated to the user with the base device or the communication device. In some embodiments, the communication device stores each time the user applies one or more treatments, creating a user history of position information, treatment characteristics, and skin condition information. Optionally, baseline conditions are updated over time based on such information. The visualization may include an image or 3D model of a skin area being treated, such as a 3D mesh object with skin condition features, treatment characteristics, or other information mapped onto the object. In some embodiments, one or more portions of the skin are highlighted. In some embodiments, the one or more portions are highlighted on the communication device, either graphically, or overlaid on a model or an image taken with the one or more sensor modules. In some embodiments, the one or more portions are areas where a treatment has been or not applied, a condition has been detected, a change in condition has been detected, or a combination thereof. In some embodiments, different colors, symbols, patterns, or the like may be used to distinguish areas of interest, such as highlighting areas where treatment has been successful in green, and areas where more treatment is needed in red. An animation of progress of the treatment overtime may include gradual changes in color (e.g., from red to green to show areas responding well to treatment) or other visual characteristics in corresponding skin areas.

In block 930, the system obtains a recommendation from a recommendation engine or adjusts treatments based on the stored information. In some embodiments, the system determines whether to adjust the one or more treatments periodically.
