Description: In this thesis, we explore the design space of using direct finger input in conjunction with a deformable physical prop for the creation and manipulation of 3D models. The user manipulates virtual models by manipulating the space on, in, and around the physical prop, in an extension of the types of manipulations which one would perform on traditional modeling media such as clay or foam. The prop acts as a proxy to the virtual model and hence as a frame of reference to the user's fingers. A prototype implementation is presented which uses camera based motion tracking technology to track passive markers on the fingers and prop. The interface supports a variety of 3D modeling operations including deforming, smoothing, and grouping of meshes. All operations are performed using the unconstrained fingers, with command input enabled by a small set of finger gestures coupled with on-screen widgets.
