abstract = {The training objective for urban warfare includes acquisition and perfection of a set of diverse skills in support of kinetic and non-kinetic operations. The US Marines (USMC) employ long-duration acted scenarios with verbal training feedback provided sporadically throughout the training session and at the end in a form of an after-action review (AAR). The inherent characteristic of training ranges for urban warfare is that they are the environments with a high level of physical occlusion, which causes many performances not to be seen by a group of instructors who oversee the training. We describe BASE-IT (Behavioral Analysis and Synthesis for Intelligent Training), a system in development that aims to automate capture of training data and their analysis, performance evaluation, and AAR report generation. The goal of this effort is to greatly increase the amount of observed behavior and improve the quality of the AAR. The system observes training with stationary cameras and personal tracking devices. It then analyzes movement and body postures, measures individual and squad-level performance, and compares it to standards and levels of performance expected in given situations. An interactive visualization component delivers live views augmented with real-time analytics and alerts; it also generates a personalized AAR review in a three-dimensional virtual or mixed reality environment, indexed by automatically extracted salient events and accompanied by summary statistics of unit performance. The approaches presented in the system have the potential to radically change the analysis and performance assessment on physical training ranges and ultimately this type of training itself.},

abstract = {This paper describes performance evaluation of a wearable augmented reality system for natural outdoor environments. 

Applied Research Associates (ARA), as prime integrator on the DARPA ULTRA-Vis (Urban Leader Tactical, 

Response, Awareness, and Visualization) program, is developing a soldier-worn system to provide intuitive ‘heads-up’ 

visualization of tactically-relevant geo-registered icons. Our system combines a novel pose estimation capability, a 

helmet-mounted see-through display, and a wearable processing unit to accurately overlay geo-registered iconography 

(e.g., navigation waypoints, sensor points of interest, blue forces, aircraft) on the soldier’s view of reality. We achieve 

accurate pose estimation through fusion of inertial, magnetic, GPS, terrain data, and computer-vision inputs. We 

leverage a helmet-mounted camera and custom computer vision algorithms to provide terrain-based measurements of 

absolute orientation (i.e., orientation of the helmet with respect to the earth). These orientation measurements, which 

leverage mountainous terrain horizon geometry and mission planning landmarks, enable our system to operate robustly 

in the presence of external and body-worn magnetic disturbances. Current field testing activities across a variety of 

mountainous environments indicate that we can achieve high icon geo-registration accuracy (<10mrad) using these 

vision-based methods.},
