Increasing agent physicality to raise social presence and elicit realistic behavior
Found in: Virtual Reality Conference, IEEE
By Joon Hao Chuah,Andrew Robb,Casey White,Adam Wendling,Samsun Lampotang,Regis Kopper,Benjamin Lok
Issue Date:March 2012
pp. 19-22
The concepts of immersion and presence focus on the environment in a virtual environment. We instead focus on embodied conversational agents (ECAs). ECAs occupy the virtual environment as interactive partners. We propose that the ECA analogues of immersion...
 
Rapid and accurate 3D selection by progressive refinement
Found in: 3D User Interfaces
By Regis Kopper, Felipe Bacim, Doug A. Bowman
Issue Date:March 2011
pp. 67-74
Issues such as hand and tracker jitter negatively affect user performance with the ray-casting selection technique in 3D environments. This makes it difficult for users to perform tasks that require them to select objects that have a small visible area, si...
 
3DUI 2010 Contest Grand Prize Winners
Found in: IEEE Computer Graphics and Applications
By Pablo Figueroa, Yoshifumi Kitamura, S├ębastien Kuntz, Lode Vanacken, Steven Maesen, Tom De Weyer, Sofie Notelaers, Johanna Renny Octavia, Anastasiia Beznosyk, Karin Coninx, Felipe Bacim, Regis Kopper, Anamary Leal, Tao Ni, Doug A. Bowman
Issue Date:November 2010
pp. 86-96, c3
The 2010 IEEE Symposium on 3D User Interfaces ran the symposium's first 3DUI Grand Prize, a contest for innovative, practical solutions to classic 3DUI problems. The authors describe the rationale for the first contest and give an analysis of all submissio...
 
Design and Evaluation of Navigation Techniques for Multiscale Virtual Environments
Found in: Virtual Reality Conference, IEEE
By Regis Kopper, Tao Ni, Doug A. Bowman, Marcio Pinho
Issue Date:March 2006
pp. 175-182
The design of virtual environments for applications that have several levels of scale has not been deeply addressed. In particular, navigation in such environments is a significant problem. This paper describes the design and evaluation of two navigation t...
   
Intercept tags: enhancing intercept-based systems
Found in: Proceedings of the 19th ACM Symposium on Virtual Reality Software and Technology (VRST '13)
By David J. Zielinski, Regis Kopper, Ryan P. McMahan, Silvia Ferrari, Wenjie Lu
Issue Date:October 2013
pp. 263-266
In some virtual reality (VR) systems, OpenGL intercept methods are used to capture and render a desktop application's OpenGL calls within an immersive display. These systems often suffer from lower frame rates due to network bandwidth limitations, implemen...
