Augmenting Image Place AR 3D Interactions for Wearable Computers

Hoang, T.N., Porter, S.R. and Thomas, B.H.

This paper presents a set of large object manipulation techniques implemented in a wearable augmented reality computer system that are optimised for the outdoor setting. These techniques supplement the current image plane approach, to provide a comprehensive solution to 3D object manipulation in an augmented reality outdoor environment. The three extended manipulation techniques, Revolve, Xscale, and Ground plane translation, are focused on using what we determined to be the best coordinate system for object rotation, scaling and translation. This paper goes on to present the generalised plane technique for the constrained translation of graphical objects on arbitrary planes to enable more complex translation operations. The paper presents the techniques from both the user interface and software development perspectives.
