Abstract

Devices, systems, and methods for autonomous, semi-autonomous, and assisted manual application of a cosmetic style to a portion of skin (e.g., skin, hair, eyebrow) of an individual. A cosmetic deposition device includes an applicator component, a position sensor, and a reservoir for compositions for the cosmetic style. A display of the cosmetic deposition device represents the portion of skin as a guide segment, and represents the applicator component as a visual indicator relative to the guide segment based on the position sensor. The depiction of the visual indicator responds to changes in the position of the applicator component relative to the portion of the biological surface 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 biological surface. These approaches enable the individual to correct application of the composition in real time.
