Book Description
The Mission Awareness Rating Scale (MARS), a subjective situation awareness (SA) rating scale designed to assess SA content and SA workload, was tested in a series of virtual environment exercises. Sixteen enlisted soldiers, working in teams of four soldiers each, completed four urban combat missions in a virtual night environment designed to simulate the experience of working with night vision goggles - NVG (PVS-7Bs) and aiming lights. In each scenario, a different approach for simulating this NVG environment was used. After each scenario was completed, each soldier completed the MARS instrument. This yielded estimates of the SA level and workload involved in four dimensions of SA - perception, understanding, projection, and knowing what decision to make. The results indicated that MARS significantly and rebustly discriminated among the different approaches, and these SA estimates were congruent with general estimates of SA content and workload while operating at night in the real world, and with the soldier's subjective rankings of the four simulated NVG environments. While promising, MARS must be validated against objective SA measures, both in the virtual environment and in the field environment. However, MARS seems to hold premise as a relatively unobtrusive and effective SA measure.

Book Description
Members of small dismounted units face growing responsibilities and challenges in both combined arms combat and in contingency operations. Field training for these diverse missions is limited by cost and environmental factors. Virtual environment (VE) technology offers a potential complement to other training methods to meet the rapidly changing requirements for military training. This report provides an assessment based on a review of the relevant research literature of the capability of VE technologies, and strategies for their use for training members of small dismounted units to acquire and maintain situational awareness. It summarizes the state of the art of research in the areas of situational awareness, team training VE technology, and instructional strategies for simulation based training. It identifies current and future challenges for providing situational awareness training to members of small dismounted units and makes recommendations for future research.

Book Description
This report documents the work conducted by the HIT Lab during a four year project titled Communicating Situation Awareness in Virtual Environments. The project was funded under the MURI (Multi-disciplinary University Research Initiative), and was intended as spin up funding to allow the Lab to achieve critical mass and momentum. As such, the goals of both the fund providers and fund recipients were successfully achieved. Over the course of the project over 30 experiments were conducted resulting in 76 publications. Support was provided for approximately 20 students, resulting in 9 theses and dissertations. A multi-disciplinary workshop was conducted, and there were active collaborations between researchers in this lab, with other labs, with government agencies and with commercial companies. The benefits of this collaboration are beginning to take effect. The focus of the research effort was tightened during the last year of the project to address five key areas. The results from experiments investigating four of these five areas are presented in this report, along with a cumulative list of all of the publications.

Book Description
Our paper describes the development and preliminary testing of three systems for unobtrusively measuring situation awareness (SA) during dismounted infantry squad-level exercises conducted with immersive Virtual Environment (VE) simulations. The SA measurement systems employ probes administered in the guise of normal radio communications, and systematic subjective ratings of squad leader behaviors and communications. Trials of the systems were conducted with three squads that differed in the experience level of the squad members and whether they had previously functioned together as intact squads. Results indicated that the measurement systems were unobtrusive and measured what they were designed to measure: squad leader SA. Ongoing modifications to the systems are described. Planned applications to other training domains are outlined.

Book Description
"This report describes a preliminary research effort to: (1) determine the effectiveness of using a virtual environment to train real world decision- making skills; (2) examine the feasibility of using a virtual environment as a test bed for developing situation awareness (SA) measurement instruments and; (3) empirically assess the role of SA in decision-making in simulated dismounted infantry environments. Seven experienced and seven inexperienced officers, role- playing a dismounted infantry platoon leader, individually conducted four urban operation scenarios (missions) in a virtual environment setting. Decision-making capability and SA were assessed for each mission. Objective decision-point accuracy improved significantly over missions. Level of experience did not impact the rate of learning. Experience did play a significant role in SA assessments. Selected SA measures also predicted a significant portion of the variance in objective decision-point scores. The research showed that real world decision-making skills could be trained using virtual environment technologies. To insure maximum benefit, virtual training must be combined with the appropriate field experience and mentoring. Conducting research in a controlled virtual environment setting permitted closer empirical scrutiny of the linkage between decision-making and SA in dismounted infantry operations and suggested new directions for further work in these areas."--DTIC.

Book Description
This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

Book Description
The Final Report describes the work performed by Quality Research under the Virtual Reality Battle Management Tool for Command, Control, and Communications Networks contract (Contract Number DAAL01-96-R-9516) with the Army Research Laboratory. The end product of this contractual effort is a software prototype to aid battlefield commanders in managing command and control networks. This prototype is known as the Situation Awareness Virtual Environment for Networks (SAVENet). The initial release of SAVENet is given the version number of SAVENet 1.0.
