An Experiment Comparing Double Exponential Smoothing and Kalman Filter-Based Predictive Tracking Algorithms
We present an experiment comparing double exponential smoothing and Kalman filter-based predictive tracking algorithms with derivative free measurement models. Our results show t...

Navigation control for mobile virtual environments
In this paper, we describe a project which uses PDAs to provide an interactive experience with a virtual environment. In particular, we focus on the navigational aspects of allowi...

Updating orientation in large virtual environments using scaled translational gain
Navigating through large virtual environments using a headmounted display (HMD) is difficult due to the spatial limitations of the tracking system. We conducted two experiments t...

Psychophysically based artistic techniques for increased perceived realism of virtual environments
The perceived realism of a computer generated image depends on the accuracy of the modeling and illumination calculations, the limitations of the display device, and the way in wh...

The effects of head-mounted display mechanics on distance judgments in virtual environments
In virtual environments that use head-mounted displays (HMD), distance judgments to targets on the ground are compressed, at least when indicated through visually-directed walking...
