This research discusses the implementation of the interactive installation, "The Ink Pool". It consists of three sections: human-machine interaction, Chinese painting simulation, and behavioral model. We integrated them to establish an interactive installation system, and then applied it in the field of digital art.

　The concept of "The Ink Pool" is attempting to combine Chinese painting with interactive technology, for the sake of continuing the spirit of traditonal art with modern digital media. The intallation is made up of virtual scenes and real objects. The virtual scenes include virtual water and swimming fishes in Chinese painting style. And the real objects contain a water vat and a ladle. Users can interact with the virtual water and fishes, which projected on the water vat, by operating the ladle directly.

　Consider the implementation of this work. In human-machine interacion, the virtual scenes and the real objects are merged seamlessly and associated dynamically, by a projector and a 3D tracker. In Chinese painting simulation, we focused on the feature of ink diffusion and the movement of strokes. We materialize both above two effects in a single stroke model, and then assembled several strokes as a fish in Chinese painting style. In behavior model, the fishes have automatic behaviors and reactions. We made them represent various behaviors, such as swimming, flocking, flee and so on, according to the control models of perception, behavior, and motor.
