    Exploring Bimanual Tool-Based Interaction in a Drawing Environment
    (2004-05-28) Butler, Colin Grant; Robert A. St. Amant, Committee Chair; Dennis Bahler, Committee Member; R. Michael Young, Committee Member
    In this document, I will present HabilisDraw DT, a drawing environment in which bimanual direct manipulation and a strong tool-use metaphor are supported via the DiamondTouch input device from Mitsubishi Electronics Research Lab. The goal of this research is to explore the viability of the various contributions of HabilisDraw DT in the development of future interfaces. The principles upon which HabilisDraw DT have been built include persistent tools that embody intuitive aspects of their physical counterparts and an approach to interface learnability that capitalizes on the user's inherent ability to use tools both separately and in conjunction with other tools. In addition to these principles, HabilisDraw DT extends the physical-virtual tool correlation with bimanual input via the MERL DiamondTouch input device and a close adherence to the direct manipulation interaction model. This paper presents background work in novel interaction and an overview of the HabilisDraw interface, then explores the benefits of a desktop metaphor that closely mimics the behavior of tools and objects in a two-dimensional drawing environment and argues for the applicability of the system's fundamental principles for improving interface usability in the future.
