Download or read book Situation Awareness in a Virtual Environment written by Michael D. Matthews and published by . This book was released on 2002 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Tactical Display for Soldiers written by National Research Council and published by National Academies Press. This book was released on 1997-01-17 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Pictorial Communication In Real And Virtual Environments written by Stephen Ellis and published by CRC Press. This book was released on 2003-09-02 with total page 651 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in the quality and accessibility of computer graphics has provided new pictorial displays and the tools with which to control them. These new display technologies have focused interest on how to design the static and dynamic images they produce to ensure effective communication. This book, based on the conference on Spatial Displays and Spatial instruments held at the Asilomar Conference Centre in 1987, focuses on the geometry of this communication. It is intended to be a source book of theoretical analysis, experimental demonstrations and practical examples from a range of contributors interested in pictorial communication, from medical artists to astronauts. The book offers the theoretical background and practical guidance needed by designers of contemporary 2D and 3D graphical computer interfaces. Its major contribution lies in its outlining of the elements of human perception and motor control which underlie the geometric design of head-mounted graphics for virtual reality displays.
Download or read book Use of Immersive Virtual Environments for Measuring and Training Situation Awareness written by and published by . This book was released on 2006 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Development and Evaluation of Communication based Measures of Situation Awareness written by Kenneth Lamar Evans and published by . This book was released on 2003 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present investigation sought to develop and field test two new behavioral measures of situation awareness (SA) that rated the content of small unit radio transmissions. Initially, a four-person team generated an item pool of 318 critical incidents of communication behavior, each intended to represent either an outstanding, typical, or poor level of SA on the part of small unit leaders. A group of 24 independent evaluators then rated the degree to which they thought each of the 318 items was related to the concept of SA. The 20 items having the highest levels of agreement among the independent evaluators within each SA level were chosen to comprise the Radio Communications Checklist of Leader Awareness (RCCOLA) and the Future Expectations of Likely Leader Awareness (FELLA) scale. Six field trials were then conducted with each of seven squad leaders and their respective squads. Based on their monitoring of squad and platoon radios, two independent raters completed separate RCCOLA checklists during each of the 42 total trials, as well as separate FELLA scales after the completion of each trial. Interrater agreement was generally high for both measures. Based on their methods of construction, we can also assume they possess some content-related validity.
