Location and head orientation tracking in GPS-denied environments
Abstract
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.
