The Tinmith System - Demonstrating New Techniques for Mobile Augmented Reality Modelling

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 solid geometry, to allow users to build up shapes with no prior knowledge of the environment. Previous work in virtual environments has tended to focus mostly on selection and manipulation, but not starting from an empty world. We demonstrate our user interface with the Tinmith-Metro application, designed to capture in city models and street furniture.
