| Short abstract "Optical Trajectory" is an artistic installation to experience dynamic color space by a simple luminescent ball and its trajectory projected on the floor.By playing with the ball which is pending from the ceiling so that you can swing it around freely, you will be able to perceive the color space model andrecognize dynamic color concept by direct experience without any interpretation. Description of the ideas and intent of this work The traditional approaches to color in art and design are based on metaphorssuch as paint and ink, and are mostly focused on its physical and static aspects. While as various digital media prevailed and color visuals are more displayed on RGB monitors in additive mixture colormethod, the knowledge and functionalities of color have been limited within those for static painting or printing media. New color model must be explored for the computational media. Following an idea of color as dynamic phenomena instead of a characteristic of physical object, I have developed an algorithm that defines dynamic color by a point in two dimensional color plane and its motionparameters (move from "where" and "which way and howfast"). The algorithm has been applied for digital RGB displayand interactive input device systems to explore dynamic color phenomena and expressions. For the installation at the SIGGRAPH 2006, I have developed a luminescent ball by full color LED devices, which is pending from the ceiling so that you can grab and move or throw it around freely. The color ofthe ball, its brightness, hue, is defined and changed by the position, and the shadow will be projected on the floor in the same colorso that the trajectory of the ball will present color dynamics in space. By playing with the ball, you will be able to perceive the color space model and recognize dynamic color concept by direct experience without any interpretation. |
