Virtual environments (VEs) allow users to experience and interact with a rich sensory environment, but most virtual worlds contain only sensory information similar to that which we experience in the physical world. <i>Information-rich</i> virtual environments (IRVEs) combine the power of VEs and information visualization, augmenting VEs with additional(More)
! Abstract— Three-dimensional user interfaces (3D UIs) support user tasks in many non-traditional interactive systems such as virtual environments and augmented reality. Although 3D UI researchers have been successful in identifying basic user tasks and interaction metaphors, evaluating the usability of 3D interaction techniques, and improving the usability(More)
In recent years, consumers have witnessed a technological revolution that has delivered more-realistic experiences in their own homes. Expanding technologies have provided larger displays with higher resolutions, faster refresh rates, and stereoscopic capabilities. These advances have increased the level of display fidelity—the objective degree of exactness(More)
Recent Standards specifications offer important but underemployed techniques to maximize access-to and distribution-of information for real-time 3D visualization over the web. This paper describes and evaluates such techniques to transform structured data such as Chemical Markup Language (CML) to different forms and contexts for Web3D delivery using(More)
Design patterns capture reusable solutions to common problems, and have been used as an approach to simplifying the development and maintenance of software systems. This paper extracts several design patterns from the implementations of recent popular 3D Visualization toolkits. While these toolkits follow the same X3D standard, their respective realizations(More)
This paper describes our recent experimental evaluation of Information-Rich Virtual Environment (IRVE) interfaces. To explore the depth cue/visibility tradeoff between annotation schemes, we design and evaluate two information layout techniques to support search and comparison tasks. The techniques provide different depth and association cues between(More)
Increasingly, biology researchers and medical practitioners are using computational tools to model and analyze dynamic systems across scales from the macro to the cellular to the biochemical level. We are using Information-Rich Virtual Environments (IRVEs) to display the results of biological simulations, and to allow users to interact with those(More)
The future standards for immersive VR workshop at the IEEE Virtual Reality 2007 Conference aimed to foster an understanding between the VR and Web3D communities. Although the fields of VR and Web-based 3D graphics tend to view their technologies as different beasts, the technologies share many requirements regarding virtual world content: modeling,(More)
