Nuance-Oriented Interfaces in Virtual Environments
Virtual Environment (VE) user interfaces do not generally support personalized interaction or the ability to adapt to the user. Our research is developing nuance-oriented interfaces that take advantage of subtle clues that users give in their actions. To that end, we have performed five experiments …

Using formalised floor-plans in the design and creation of virtual environments
Virtual Reality (VR) is an new and exciting medium waiting to be fully explored and capitalised by media experts. The advantages of the 3D graphics andinteractive nature of VR allows unique communication opportunities from a content expert to a target audience. Despite the attractiveness of VR as a …

Computational Methods for Natural Walking in Virtual Reality
Virtual reality (VR) allow users to feel as though they are really present in a computer-generated virtual environment (VE). A key component of an immersive virtual experience is the ability to interact with the VE, which includes the ability to explore the virtual environment. Exploration of VEs …

Migrating Three Dimensional Interaction Techniques
Multiplatform virtual environment (VE) development is fast-becoming a realization for today’s developers. 3D user interfaces (3DUIs) can easily be ported to a variety of VE systems. However, few researchers have addressed the need to intelligently migrate 3DUIs across VE systems. We claim that the …

An Examination of Personality as a Predictor of Guard Behavior in a Virtual Environment
… realistic training tools that can provide a safe environment in which to acquire skills that will generalize to real world tasks. A virtual environment (VE) is one such tool. The focus of the present study was to evaluate a VE as a training tool for military guards. The first goal was to examine …

User-centered Virtual Environment Assessment And Design For Cognitive Rehabilitation Applications
Virtual environment (VE) design for cognitive rehabilitation necessitates a new methodology to ensure the validity of the resulting rehabilitation assessment. We propose that benchmarking the VE system technology utilizing a user-centered approach should precede the VE construction. Further, user …
