Choosing between competing goals during walking in a virtual environment

Walking Through A Very Large Virtual Environment

Choosing a Selection Technique for a Virtual Environment

Bearing in mind the difficulty required to create virtual environments, a platform for Setting-up Interactive Virtual Environments (pSIVE) was created to help non-specialists benefit from virtual applications involving virtual tours where users may interact with elements of the environment to extract contextual information. The platform allows creating virtual environments and setting up their ...

The Perception of Walking Speed in a Virtual Environment

Studies of locomotion in virtual environments assume that correct geometnc principles define the relationship between walking speed and environmental flow. However, we have observed that geometrically correct optic flow appears to be too slow during simulated locomotion on a treadmill. Experiment I documents the effect in a head-mounted display. Experiment 2 shows that the effect is eliminated ...

Walking Through a Very Large Virtual Environment in Real-time

Users expect high and constant rendering frame rates when they interactively navigate in a Virtual Environment (VE). However, when the VE is too large to t into the main memory, the frame rates can become unacceptable. In this paper, we combine walkthrough semantics and database techniques, such as indexing, caching and prefetching, to improve the performance of walkthrough of a very large VE. ...

Reduced Visual Input Affects Gait Characteristics during Treadmill Walking in a Virtual Environment

INTRODUCTION Vision is one of the most important sensory systems in controlling locomotion [1]. Humans rely on visual information from the environment to mediate the foot-placement during walking [1,2]. It has been shown that temporal and spatial features of gait are altered by reducing visual input [3], resulting in an increase of falls. Furthermore, the reduction of lighting was recognized as...
