CSCW; in this setting computers can provide the same type of collaborative information that people have in face-to-face interactions, such as communication by object manipulation, voice and gesture [1]. Work on the DIVE project [2], GreenSpace [3] and other fully immersive multi-participant virtual environments has shown that collaborative work is indeed(More)
In this paper we address the problems of virtual object interaction and user tracking in a table-top Augmented Reality (AR) interface. In this setting there is a need for very accurate tracking and registration techniques and an intuitive and useful interface. This is especially true in AR interfaces for supporting face to face collaboration where users(More)
The Go-Go immersive interaction technique uses the metaphor of interactively growing the user’s arm and non-linear mapping for reaching and manipulating distant objects. Unlike others, our technique allows for seamless direct manipulation of both nearby objects and those at a distance.
ate intuitive computer interfaces by blending reality and virtual reality. The goal is for people to interact with the digital domain as easily as the real world. Various approaches help us achieve this—in the area of tangible interfaces, we use real objects as interface widgets; in augmented reality, researchers overlay 3D virtual imagery onto the real(More)
Although Augmented Reality technology was first developed over forty years ago, there has been little survey work giving an overview of recent research in the field. This paper reviews the tenyear development of the work presented at the ISMAR conference and its predecessors with a particular focus on tracking, interaction and display research. It provides(More)
Virtual Reality (VR) appears a natural medium for computer supported collaborative work (CSCW). However immersive Virtual Reality separates the user from the real world and their traditional tools. An alternative approach is through Mixed Reality (MR), the overlaying of virtual objects on the real world. This allows users to see each other and the real(More)
The MagicBook is a Mixed Reality interface that uses a real book to seamlessly transport users between Reality and Virtuality. A vision-based tracking method is used to overlay virtual models on real book pages, creating an Augmented Reality (AR) scene. When users see an AR scene they are interested in they can fly inside it and experience it as an(More)
Mobile phones are an ideal platform for augmented reality. In this paper we describe how they can also be used to support face to face collaborative AR gaming. We have created a custom port of the ARToolKit library to the Symbian mobile phone operating system and then developed a sample collaborative AR game based on this. We describe the game in detail and(More)
