Directional Interfaces for Wearable Augmented Reality

Abstract

Wearable Augmented Reality can be used to overlay information onto the real world. Directional interfaces in W.A.R. aid users to orient themselves so that previously invusible targets are now inside their field of view. This is relevant when the user tries to find the next waypoint during a navagational task. We surveyed directuinal interfaces that have been used in augmented reality previously and compared their efficiency. We have found that a circular compass is the most efficient way to provide orientation cues.
