Figure 1: Luxomatic is a performance animation system that uses information derived from computer vision processes to drive the animation of a graphical character (a Luxo lamp). In this tech note we describe the Luxomatic performance animation system, a computer vision system that tracks a puppeteer’s hand to map hand position and shape to an animated graphical model. An eigenvector decomposition of typical hand images are used to both track the hand and extract two-dimensional pose information in real time. Luxomatic was constructed as a class project in 1997.
