Precise Manipulation at a Distance in Wearable Outdoor Augmented Reality

In this paper we present our research directions on the issue of precise manipulation and modeling interactions for outdoor augmented reality. We also discuss the related issues of action at a distance techniques and the relationship between virtual and physical objects. Techniques for action at a distance are limited by the accuracy of the sensors, as well as the efficiency of tracking solution. We examine possible solutions for precise interactions including symbolic entry of data, grid snapping, and alignment operations. Grid snapping and relative snapping are also discussed as ways to improve precision.
