Wayfinding has been investigated by multiple researchers in the context of a Landmark-to-Route-to-Survey learning construct that relies on multiple and – across the population – varying cognitive mechanisms. The development of GPS-based cellphone navigation aids has made wayfinding easier for most situations, though for First Responders and Ground Warfighters, the need to navigate in GPS-denied environments without such assistance may compromise their ability to get their job done as well as their safety. We will discuss wayfinding research and look at bio-inspired navigation methods because they may point us to navigation solutions that do not rely on GPS. Finally, we will discuss a hybrid inertial and visual navigation and tracking system that we have integrated into an augmented reality ensemble for high stress, GPS-denied applications with some recommendations for future growth.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
