This paper presents a first person outdoor/indoor augmented reality application ARQuake that we have developed. ARQuake is an extension of the desktop game Quake, and as such we are investigating how to convert a desktop first person application into an outdoor/indoor mobile augmented reality application. We present an architecture for a low cost,(More)
This paper presents new techniques for capturing and viewing on site 3D graphical models for large outdoor objects. Using an augmented reality wearable computer, we have developed a software system, known as Tinmith-Metro. Tinmith-Metro allows users to control a 3D constructive solid geometry modeller for building graphical objects of large physical(More)
Touch is the most intimate and inherently private human sense and provides the potential for discrete, low social weight human computer interaction. This paper presents initial research findings on issues of integrating a vibrotatcitle display and support electronics into a standard clothing insert, the shoulder pad. Research on construction methods is(More)
This paper presents the development of the Tourist Guide, a location based tourist guide application for the outdoor environment. Our focus for this project is on software support for location based applications; we are not just interested in the location but also other elements of the user's context, such as buildings in view, attractions and equipment(More)
This paper presents user interface technology, using a glove based menuing system and 3D interaction techniques. It is designed to support applications that allow users to construct simple models of outdoor structures. The construction of models is performed using various 3D virtual reality interaction techniques, as well as using real time constructive(More)
If judiciously applied, animation techniques can enhance the look and feel of computer applications that present a graphical human interface. Such techniques can smooth the rough edges and abrupt transitions common in many current graphical interfaces, and strengthen the illusion of direct manipulation that many interfaces strive to present. To date, few(More)
This paper presents the use of a wearable computer system to visualise outdoor architectural features using augmented reality. The paper examines the question-How does one visualise a design for a building, modification to a building, or extension to an existing building relative to its physical surroundings? The solution presented to this problem is to use(More)
BACKGROUND Recurrence of child maltreatment is a major problem, yet little is known about approaches to reduce this risk in families referred to child protection agencies. Since home visitation by nurses for disadvantaged first-time mothers has proven effective in prevention of child abuse and neglect, we aimed to investigate whether this approach might(More)
