This paper presents a new software architecture for 3D mixed reality applications, named Tinmith-evo5. Currently there are a limited number of existing toolkits for the development of 3D mixed reality applications, each optimised for a particular feature but at the detriment of others. Complex interactive user interfaces and applications require extensive(More)
This paper describes the combination of two technologies , augmented reality and GIS, to provide a new way to visualise viticulture GIS data using outdoor mobile computers. Viticulturists use GIS to assist with accurately understanding the parameters that affect their yields and quality of the grapes from different vineyards. The ability to view this data(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)
This paper describes how we have used the ARToolKit to perform three degree of freedom tracking of the hands, in world coordinates, which is used to interact with a mobile outdoor augmented reality computer. Since ARToolKit generates matrices in camera coordinates, if errors occur during the calibration process, it is difficult to extract out real world(More)
This paper presents a new user interface technology known as ThumbsUp, which we have designed and developed for use with mobile outdoor augmented reality systems. Using a simple pair of vision tracked pinch gloves and a new menuing system, a user is able to control an augmented reality system in outdoor environments under poor tracking conditions with a(More)
ith the advent of commercially available affordable wearable computers and head-mounted displays (HMDs), it is possible to develop augmented reality entertainment applications suitable for an outdoor environment. We extended an existing desktop game and developed it into the ARQuake system [4], one of the first systems that allows users to play augmented(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)
To date augmented realities are typically operated in only a small deened area, in the order of a large room. This paper reports on our investigation into expanding augmented realities to outdoor environments. The project entails providing visual navigation aids to users. A w earable computer system with a see-through display, digital compass, and a(More)
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)
