Traditionally paint work is always done on a piece of paper, canvas, on a wall or on the surface of some material. Augmenting it into 3D virtual reality space is a breakthrough. By the inspiration of Jackson Pollock's “action painting”, human body could act as a paintbrush to drive the paintings by his/her body motion. Fusing the concepts of action painting and virtual reality together not only introduces new aesthetic perspectives on paint art, but also raises potential multi-disciplinary researches over the end product. In this paper, a framework is presented for building an action studio to experiment a new form of paint art that utilizes human body as paintbrushes to drive the painting process and then visualizes the paint work in a 3D canvas in real-time. Further, based on its inherent correlation characteristic of human behavior and cognition, the system could be extended for a joint research with other potential disciplines such as music and psychotherapy.
