Abstract

Devices, systems, and methods for autonomous, semi-autonomous, and assisted manual application of a cosmetic style to a portion of skin of an individual. A printer device includes a printer applicator, a position sensor, and a reservoir for compositions for the cosmetic style. A display of the printer device represents the portion of skin as a plurality of guide segments, and represents the printer applicator as a visual indicator relative to the plurality of guide segments based on the position sensor. The depiction of the visual indicator responds to changes in the position of the printer applicator relative to the portion of the skin to visually guide the individual to accurately apply the cosmetic style, and a feedback device alerts the individual if the application deviates from the portion of the skin. These approaches enable the individual to correct application of the composition in real time.
