    Java Mirrors: Building Blocks for Interacting with High Performance Applications
    (Georgia Institute of Technology, 2005) Chen, Yuan ; Schwan, Karsten ; Rosen, David W.
    Mirror objects are the key building blocks in the virtual 'workbenches' and 'portals' for scientific and engineering applications constructed by our group. This paper uses mirror objects in the implementation of the RTTB design workbench, which controls components of the RTTB rapid tooling and prototyping testbed. Mirror objects continuously mirror the states of remote software or even hardware entities, and the operations performed on mirrors are automatically propagated to these entities. Thus, end users perceive mirrors as virtualizations of remote entities. This paper presents the concept of mirror objects, their JMOSS Java-based implementation, the interoperation of JMOSS Java mirrors with the CORBA-based MOSS mirror object implementation, demonstrations of mirror functionality and utility with a virtual `design workbench' used by engineers for rapid tooling and prototyping processes, and performance evaluations of mirror objects. We also present initial evaluations of JMOSS mirrors in mobile environments, where workbench users can continue their PC-based online interactions via handheld devices carried to the shopfloor.

    Finger Sculpting with Digital Clay: 3D Shape Input and Output through a Computer-Controlled Real Surface
    (Georgia Institute of Technology, 2003) Book, Wayne J. ; Glezer, Ari ; Ebert-Uphoff, Imme ; Shaw, Christopher D. ; Rossignac, Jarek ; Allen, Mark G. ; Rosen, David W. ; Askins, Stephen Alexander ; Bai, Jing ; Bosscher, Paul Michael ; Gargus, Joshua ; Kim, Byungmoon ; Llamas, Ignacio ; Nguyen, Austina Nga ; Yuan, Guang ; Zhu, Haihong
    The NSF Digital Clay project is focused on the design, prototyping, integration, and validation of a computer-controlled physical device capable of taking any of a wide range of possible shapes in response to changes in a digital 3D model or to changes in the pressure exercised upon it by human hands. Although it clearly is a natural and unavoidable evolution of 3D graphical user interfaces, its unprecedented capabilities constitute a major leap in technologies and paradigms for 3D display, for 3D input, and for collaborative 3D design. In this paper, we provide an overview of the Digital Clay project and discuss the challenges, design choices, and initial solutions for a new Finger Sculpting interface designed for the Digital Clay and prototyped using conventional 3D I/O hardware.
