An integrated approach to rotorcraft human factors research

As the potential of civil and military helicopters has increased, more complex and demanding missions in increasingly hostile environments have been required. Users, designers, and manufacturers have an urgent need for information about human behavior and function to create systems that take advantage of human capabilities, without overloading them. Because there is a large gap between what is known about human behavior and the information needed to predict pilot workload and performance in the complex missions projected for pilots of advanced helicopters, Army and NASA scientists are actively engaged in Human Factors Research at Ames. The research ranges from laboratory experiments to computational modeling, simulation evaluation, and inflight testing. Information obtained in highly controlled but simpler environments generates predictions which can be tested in more realistic situations. These results are used, in turn, to refine theoretical models, provide the focus for subsequent research, and ensure operational relevance, while maintaining predictive advantages. The advantages and disadvantages of each type of research are described along with examples of experimental results

The role of the research simulator in the systems development of rotorcraft

The potential application of the research simulator to future rotorcraft systems design, development, product improvement evaluations, and safety analysis is examined. Current simulation capabilities for fixed-wing aircraft are reviewed and the requirements of a rotorcraft simulator are defined. The visual system components, vertical motion simulator, cab, and computation system for a research simulator under development are described

AN ANALYSIS OF THE MARINE CORPS AVIATION TRAINING SYSTEM REQUIREMENTS LIFE CYCLE

This capstone applied project examines the suitability of the current requirements life cycle for Marine Corps aviation training systems, including new programs and upgrades. Methodology includes a comprehensive review of existing policies and processes as well as interviews with key stakeholders. Analysis has identified weaknesses in the areas of training-focused requirements generation as well as portfolio management across Marine Corps training system programs. Recommendations include integrating modeling and simulation (M&S) expertise into the Training Management Process (TMP) and full implementation of Training Systems Certification (TSC) and Systematic Team Assessment of Readiness Training (START) tools to improve requirement relevancy to training needs as well as improved portfolio management for Marine Corps training systems led by Marine Corps Training and Education Command (TECOM). This capstone applied project concludes with recommendations for further study related to these matters.Major, United States Marine CorpsMajor, United States Marine CorpsApproved for public release.

Trends in virtual reality technologies for the learning patient

NextMed convened the Medicine Meets Virtual Reality 22 (MMVR 22) conference in 2016. Since 1992, the conference has brought together a diverse group of researchers to share creative solutions for the evolving challenge of integrating virtual reality tools into medical education. Virtual reality (VR) and its enabling technologies utilize hardware and software to simulate environments and encounters where users can interact and learn. The MMVR 22 symposium proceedings contain projects that support a variety of learners: medical students, practitioners, soldiers, and patients. This report will contemplate the trends in virtual reality technologies for patients navigating their medical and healthcare learning. The learning patient seeks more than intervention; they seek prevention. From virtual humans and environments to motion sensors and haptic devices, patients are surrounded by increasingly rich and transformative data-driven tools. Applied data enables VR applications to simulate experience, predict health outcomes, and motivate new behavior. The MMVR 22 presents investigations into the usability of wearable devices, the efficacy of avatar inclusion, and the viability of multi-player gaming. With increasing need for individualized and scalable programming, only committed open source efforts will align instructional designers, technology integrators, trainers, and clinicians. Curriculum and InstructionCurriculum and Instructio

VIRTUAL REALITY GROUND FORCE COMMANDER TRAINER

The complexity of battlespace is guaranteed to increase over time. The problem arising is that with today’s innovative battlefield and the ever-connected environment, our junior officers are receiving more information, data, and feedback than ever before. With this increased amount of information at their fingertips, we expect them to process this information and make these real-world decisions faster and more precisely than before. Suppose we do not train our leaders to properly handle this information and prioritize tasks, and help them to avoid becoming overwhelmed by the multiple tasks they address. In that case, we run the risk of them becoming cognitively overloaded and making bad decisions based on poor judgment or emotions. These impulsive decisions highly increase the chance of mission failure. Today, we are expecting more out of our ground force commanders (GFCs) in their doctrinal skill set, decision making abilities under pressure, and cognitive performance; however, we are failing to adapt and advance our training at the same pace and level that we expect them to perform. If we cannot teach it, how can we expect our operators to perform at this new level in a new environment? The question: How can Special Operations Forces improve cognitive decision processing under stress and prepare GFCs for future conflicts? Our conclusion is that the adoption of advanced training and technology will help to keep SOF GFCs at the leading edge of combat proficiency.Lieutenant Junior Grade, United States NavyLieutenant, United States NavyApproved for public release.

The evaluation of pilots performance and mental workload by eye movement

Pilots make important decisions often using ambiguous information, while under stresses and with very little time. During flight operations detecting the warning light of system failure is a task with real-world application relates to measurement of pilot's performance and eye movement. The demand for a pilot’s visual and situational awareness in multiple tasks can be detrimental during pilots’ mental overload conditions. The purpose of this research is to evaluate the relationship between pilot’s mental workload and operational performance by eye tracking. Collecting eye movement data during flight operations in a virtual reality of flight simulator provided useful information to analysis participants’ cognitive processes. There were 36 pilots participated in this research, the experience of flight hours between 320 and 2,920, the range of age between 26 and 51 years old. The apparatus included Applied Science Laboratories (ASL) eye tracking, IDF flight simulator and NASA_TLX for data collection. The results show that pilots with high SA detecting hydraulic malfunction have shorter total fixation duration on Air Speed Indicator and longer total fixation duration on Altitude Indicator, Vertical Speed Indicator, Right multi-display and Left multi-display compared with pilots without detecting the signal of hydraulic malfunction. Pilots’ total fixation time on Integration Control Panel, Altitude Indicator, Attitude Indicator and Right Multi-display, and pilots’ subjective rating on NASA-TLX effort dimension for the mission of close pattern have significant relationship with pilots’ performance on the operational time for completing the tactic mission. Experienced pilots operate aircraft familiar with monitoring Airspeed Indicator and kinetic maneuvering result in less fuel consumption. This study could provide guidelines for future training design to reduce pilots mental workload and improve situational awareness for enhancing flight safety

Artificial Reversible Skin

This project aims to improve the realism of medical simulation mannequins by developing an adaptable system for the skin that is capable of displaying physiological changes in the skin caused by conscious and unconscious perturbations. A design of an artificial skin is developed, which uses organic light emitting diode (OLED) displays implanted underneath the skin of a medical simulation mannequin. After performing fatigue analysis and constructing a proof of concept, it is shown that the use of strategically placed displays can realistically simulate color changes similar to the human physiology
