Projector-Guided Painting

Project Description:
This paper presents a novel interactive system for guiding artists to paint using traditional media and tools. The enabling technology is a multi-projector display capable of controlling the appearance of an artist.s canvas. Artists are guided by this display-on-canvas to paint according to a process model we designed to solve 3 common problems with novice painters. The artist paints according to a linear process of painting in layers and, within each layer, a set of colors. Each component of our model of the painting process has an associated interaction mode. Preview mode shows the entire layer as the current painting goal. Blank mode reveals the state of the painting. Color selection mode displays where to paint a target color. Color mixing mode shows how to mix it and orientation mode shows how to paint it. These interaction modes enable the novice to focus on painting sub-tasks in order to simplify the painting process while providing technical guidance ranging from high-level composition to detailed brushwork. We present results of a user study that quantify the benefit that our system can provide to a novice painter.
