    An Introduction to 3D User Interface Design

    3D user interface design is a critical component of any virtual environment (VE) application. In this paper, we present a broad overview of three-dimensional (3D) interaction and user interfaces. We discuss the effect of common VE hardware devices on user interaction, as well as interaction techniques for generic 3D tasks and the use of traditional two-dimensional interaction styles in 3D environments. We divide most user interaction tasks into three categories: navigation, selection/manipulation, and system control. Throughout the paper, our focus is on presenting not only the available techniques, but also practical guidelines for 3D interaction design and widely held myths. Finally, we briefly discuss two approaches to 3D interaction design, and some example applications with complex 3D interaction requirements. We also present an annotated online bibliography as a reference companion to this article

    Haptic-GeoZui3D: Exploring the Use of Haptics in AUV Path Planning

    Get PDF
    We have developed a desktop virtual reality system that we call Haptic-GeoZui3D, which brings together 3D user interaction and visualization to provide a compelling environment for AUV path planning. A key component in our system is the PHANTOM haptic device (SensAble Technologies, Inc.), which affords a sense of touch and force feedback – haptics – to provide cues and constraints to guide the user’s interaction. This paper describes our system, and how we use haptics to significantly augment our ability to lay out a vehicle path. We show how our system works well for quickly defining simple waypoint-towaypoint (e.g. transit) path segments, and illustrate how it could be used in specifying more complex, highly segmented (e.g. lawnmower survey) paths

    Cross-Dimensional Gestural Interaction Techniques for Hybrid Immersive Environments

    Get PDF
    We present a set of interaction techniques for a hybrid user interface that integrates existing 2D and 3D visualization and interaction devices. Our approach is built around one- and two-handed gestures that support the seamless transition of data between co-located 2D and 3D contexts. Our testbed environment combines a 2D multi-user, multi-touch, projection surface with 3D head-tracked, see-through, head-worn displays and 3D tracked gloves to form a multi-display augmented reality. We also address some of the ways in which we can interact with private data in a collaborative, heterogeneous workspace

    Analysis domain model for shared virtual environments

    Get PDF
    The field of shared virtual environments, which also encompasses online games and social 3D environments, has a system landscape consisting of multiple solutions that share great functional overlap. However, there is little system interoperability between the different solutions. A shared virtual environment has an associated problem domain that is highly complex raising difficult challenges to the development process, starting with the architectural design of the underlying system. This paper has two main contributions. The first contribution is a broad domain analysis of shared virtual environments, which enables developers to have a better understanding of the whole rather than the part(s). The second contribution is a reference domain model for discussing and describing solutions - the Analysis Domain Model
