Retrieving information presented visually is difficult for visually disabled users. Current accessibility technologies, such as screen readers, fail to convey presentational layout or structure. Information presented in graphs or images is almost imp

We present a novel approach for visual tracking of structured behaviour as observed in human-computer interaction. An automatically acquired variable-length Markov model is used to represent the high-level structure and temporal ordering of gestures.

The head-mounted display (HMD) is a popular form of virtual display due to its ability to immerse users visually in virtual environments (VEs). Unfortunately, the user's virtual experience is compromised by the narrow field of view (FOV) it affords,

There are many real-world applications of Virtual Reality requiring the construction of complex and accurate three-dimensional models that represent real environments. In this paper, we describe a rapid and robust semi-automatic system that allows su

We present a Hybrid Geometric-Image Based Rendering (HGIBR) system for displaying very complex geometrical models at interactive frame rates. Our approach replaces distant geometry with a combination of image-based representations and geometry, while

Photometric reconstruction is the process of estimating the illumination and surface reflectance properties of an environment, given a geometric model of the scene and a set of photographs of its surfaces. For mixed-reality applications, such data is

This paper describes a publicly available virtual reality (VR) system, GNU/MAVERIK, which forms one component of a complete VR operating system. We give an overview of the architecture of MAVERIK, and show how it is designed to use application data i

This paper presents a case study of navigation and manipulation in a large, geometrically complex, virtual environment representing an off-shore gas platform. Our approach is based on a combined force-field navigation and collision detection algorith

The authors describe a novel algorithm for computing view-independent finite element radiosity solutions on distributed shared memory parallel architectures. Our approach is based on the notion of a subiteration being the transfer of energy from a si

In this paper we present a general technique for real-time display of very large models. We combine methods for culling and level-of-detail management with wire-frame representations, generated dynamically from a hierarchy of bounding volumes. Smooth
