Abstract

This paper proposes a real-time dynamic interface DO-IT (deformable object as input tool) for intuitive 3-D plastic geometric operation. When a user bends, presses and twists a real deformable object as an input tool, its 3-D deformation is electrically measure and applied to a virtual control volume on a computer display. Then the deformation of the control volume is mapped to an objective shape model on the display using free-form deformation algorithm. With this interface, a user can three-dimensionally deform a shape model on a display intuitively with passive hap tic feedback of the reaction of the input tool. The authors previously implemented this interface concept with an elastic input tool made of electrically conductive foam rubber. Although our software can maintain the deformed shape on the model in a display, the elastic input tool itself-returns to the original shape when a user releases it. The difference between the shape of the model and that of the tool sometimes spoils intuitiveness. To solve such problems, a plastic input tool made of electrically conductive clay is designed and fabricated. Its efficacy and feasibility are examined through basic experiments and prototype system performance.
