Wet Paint

Wet Paint is a tangible interface based on a touch screen display powered by a Java framework for layered viewing and interaction with multi-spectral scans of artwork, that allows users to scrape through layers of a painting and flip through different spectra. The scans of the paintings with different spectra of light reveal unique information about the artwork that is not visible to the naked eye. For example, while we see the visible light spectrum with our eyes, the infrared scan shows the undersketch of the painting, an ultraviolet scan shows pigment information, and the x-ray scan reveals information about the working medium and mounting surface. I was one of two principal engineers on the project, along with Xiao Xiao, and was responsible for many of the core scraping algorithms and object-oriented framework behind Wet Paint, including integrating the desktop application with the Flickr API to allow dynamic content addition such as notes, audio files, and comments from a local and global community.

Wet Paint

Wet Paint was named the most innovative student research project at the 2008 HKN Project Expo and was presented at MIT Tech Fair 2008 alongside industry leaders in technology. The project was publicly debuted at the New York Italian Cultural Institute in November 2008 and the NYC Metropolitan Museum of Art in June 2009. A conference paper on the project - "Wetpaint: Scraping Through Multi-layered Images" - was published and presented at CHI in April 2009. I worked on Wet Paint with Leonardo Bonanni and Xiao Xiao of the Tangible Media Group. The video accompanying our publication including a demonstration of Wet Paint is shown below:
