Widget Manipulation Revisited: a Case Study in Modeling Interactions Between Experimental Conditions
(The Eurographics Association, 2007)
Widgets are often used to perform control tasks in three-dimensional (3D) virtual environments (VEs). Spatial interactions through widgets require precise 3D manipulations, and several design aspects of VEs contribute to ...
Three Extensions to Subtractive Crosstalk Reduction
(The Eurographics Association, 2007)
Stereo displays suffer from crosstalk, an effect that reduces or even inhibits the viewer s ability to correctly fuse stereoscopic images. In this paper, three extensions for improved software crosstalk reduction are ...
Search Space Reduction in Optical Tracking
(The Eurographics Association, 2003)
In this paper we present a practical method for reducing the space when searching for point patterns in optically tracked virtual reality applications. The method uses a predictor to estimate the future position of a point. ...
Tangible Interaction for 3D Widget Manipulation in Virtual Environments
(The Eurographics Association, 2008)
In this paper we explore the usage of tangible controllers for the manipulation of 3D widgets in scientific visualization applications. Tangible controllers can be more efficient than unrestricted 6-DOF devices, since many ...
Modeling the Effect of Force Feedback for 3D Steering Tasks
(The Eurographics Association, 2011)
Path steering is an interaction task of how quickly one may navigate through a path. The steering law, proposed by Accot and Zhai [AZ97], is a predictive model which describes the time to accomplish a 2D steering task as ...
The Effect of Varying Path Properties in Path Steering Tasks
(The Eurographics Association, 2010)
Path steering is a primitive 3D interaction task that requires the user to navigate through a path of a given length and width. In a previous paper, we have conducted controlled experiments in which users operated a pen ...
A Framework for Performance Evaluation of Model-Based Optical Trackers
(The Eurographics Association, 2008)
We describe a software framework to evaluate the performance of model-based optical trackers in virtual environments. The framework can be used to evaluate and compare the performance of different trackers under various ...
Designing 3D Selection Techniques Using Ballistic and Corrective Movements
(The Eurographics Association, 2009)
The two-component model is a human movement model in which an aimed movement is broken into a voluntary ballistic movement followed by a corrective movement. Recently, experimental evidence has shown that 3D aimed movements ...
Time Critical Computing and Rendering of Molecular Surfaces Using a Zonal Map
(The Eurographics Association, 2000)
We describe the zonal map, a data structure used for the visualization of large, time dependent molecular configurations in virtual environments. The governing idea of the zonal map is to use the user s line of sight to ...
