Exploring the Design Space of Multiscale 3D Orientation (4:25 min.)
Video title (x:xx min.)
Recently, research in 3D computer graphics and interaction has started to move beyond the narrow domain of single object authoring and inspection, and has begun to consider complex multiscale objects and environments. This generalization of problem scope calls for more general solutions, which are more akin to information visualization techniques than traditional computer graphics approaches.We consider the general problem of the users understanding of their position and orientation within a multiscale 3D scene and propose a classification of the design space. To ground this theoretical discussion, we present initial explorations into grouping techniques, visualizations, and interactions to facilitate multiscale 3D orientation.
While advances in computing have empowered users to design and interact with objects in virtual three-dimensional space, little effort has been made to improve or facilitate interaction with the viewpoint. Once we begin to consider this problem, we find that it effectively spans a huge problem domain with many special cases. It touches on many of the fundamental difficulties in 3D interaction: being inside an object vs. being outside, how close is the viewpoint to the object, what is the user looking at and/or is interested in, egocentric vs. exocentric thinking, parallel vs. perspective viewing projections, multiscale and level-of-detail issues, what kind of data is being examined (abstract, incomplete, photoreal, engineering, CAD, entertainment, medical, simulation, etc.), and what is the user task (authoring, inspecting, etc.). Additional technical issues include correct handling of the clipping planes and floating-point precision problems. To help understand and address some of these issues, we have an ongoing research program to improve the state-of-the-art in 3D navigation.
Designing user interfaces for interacting with 3D data involves a number of factors that are not found in traditional 2D interfaces. In this project, we explore subtle yet critical aspects of 3D control and feedback. A number of research outcomes have been integrated into several Autodesk products and we continue to explore this complex area.
This project investigates the properties and qualities of multiscale datasets in an effort to gain critical insights needed, in user experience and understanding, to make progress in increasingly complex contexts.
