ABSTRACT
We demonstrate ChromaNails, a physical nail reprogramming device that enables high-resolution multi-color textures on fingernails using photochromic nail polish for on-body interaction. Our ChromaNails reprogrammer uses a miniature RGB projector and a UV light source to project different wavelengths of light onto our photochromic nail polish. We create this nail polish by mixing cyan, magenta, and yellow (CMY) photochromic dye into a base substrate polish. This enables us to control the saturation and desaturation of the CMY particles inside our nail polish to various colors inside the CMY color space. Our integrated user interface enables laypeople to select their preferred color texture and adapts to various nail shapes. We demonstrate the usefulness of ChromaNails for on-body interaction through four application examples on reprogrammable fingernail QR codes, on-body calendars, security, and fashion.

Photo-Chromeleon: Re-Programmable Multi-Color Textures Using Photochromic Dyes
UIST '19: Proceedings of the 32nd Annual ACM Symposium on User Interface Software and TechnologyIn this paper, we present a method to create re-programmable multi-color textures that are made from a single material only. The key idea builds on the use of photochromic inks that can switch their appearance from transparent to colored when exposed to ...
Photo-Chromeleon: Re-Programmable Multi-Color Textures Using Photochromic Dyes
SIGGRAPH '20: ACM SIGGRAPH 2020 Emerging TechnologiesIn most situations in the real world, once an object is fabricated, the color is permanent and cannot be changed again. For the Emerging Technologies exhibit, we will present a technology to create re-programmable multi-color textures that are made from ...
