The design project reported in this paper examined female pilots’ experiences with how well or poorly cockpit design allowed them to safely accomplish their flying missions. The general aviation aircraft cockpit is not designed for female pilots, often causing them to find ways to adapt to the cockpit in order to operate the aircraft safely. Two primary focal areas for adaptations address issues with accessibility of controls and “viewability” inside and outside the cockpit. The design team used a Situation Awareness-Oriented Interface Design (SAOD) approach in preparing cockpit design recommendations for general aviation aircraft that would accommodate female pilots.
How Does Robotic Surgery Influence Communication, Leadership, And Team Outcomes? A Multimethod Examination., Jordan E. Rogers
How Does Robotic Surgery Influence Communication, Leadership, And Team Outcomes? A Multimethod Examination., Jordan E. Rogers
Doctoral Dissertations and Master's Theses
The practice of delivering surgical care has evolved to be less invasive to the patients undergoing surgery. Minimally-invasive surgery can be practiced through traditional laparoscopic methods as well as with robotic technology that displaces the surgeon from the operating table. Robotic surgery has been cited to be safer and more effective than traditional laparoscopic surgery; however, little research has endeavored to investigate the role of surgical modality upon aspects of teamwork. This dissertation contributes to the human factors and teamwork literature by evaluating how surgical modality may influence communication, shared leadership, and team outcomes. Multiple methods were employed to study …
Identifying Criteria To Predict Army Rifle Marksmanship Proficiency, Katlin Makina Anglin
Identifying Criteria To Predict Army Rifle Marksmanship Proficiency, Katlin Makina Anglin
Doctoral Dissertations and Master's Theses
The United States Army requires each Soldier to develop marksmanship proficiency in an effort to achieve combat readiness. Soldiers currently develop marksmanship proficiency through Basic Rifle Marksmanship (BRM) training, but significant skill deficiencies are apparent at the end of training. These skill deficiencies remain throughout training because instructors rarely assess Soldiers objectively before the final qualification, reducing the opportunity for instructors to diagnose skill deficiencies until it is too late. Therefore, the goal of the current research is to identify individual differences and sensor-based performance measures for inclusion in a formative assessment during BRM training. The results of the current …

Ranking Of Human Senses In Relation To Different In-Flight Activities Contributing To The Comfort Experience Of Airplane Passengers, Joyce Bouwens, Suzanne Hiemstra-Van Mastrigt, Peter Vink
International Journal of Aviation, Aeronautics, and Aerospace
Bubb, Bengler, Grünen, and Vollrath (2015) identified six environmental comfort factors and ordered them from most important to least important (smell, light, vibrations, sound, climate and anthropometry). This paper attempts to verify whether this suggested order of comfort-related factors also applies to the expectations of aircraft passengers. For this purpose, two studies were carried out. First, a survey was conducted among 183 aircraft passengers between 19 and 64 years old. In this survey, respondents were asked to rank six comfort factors by selecting the most important factor from 15 pairs of factors (e.g. light versus smell). The respondents indicated anthropometry …
Effect Of Anthropometric Variability On Middle-Market Aircraft Seating, Tara C. Sriram
Effect Of Anthropometric Variability On Middle-Market Aircraft Seating, Tara C. Sriram
International Journal of Aviation, Aeronautics, and Aerospace
A middle-of-market aircraft, or MoMA, is defined as an aircraft capable of flying 180-250 passengers without refueling for 2,300-5,800 miles(~2,000-5,000 nautical miles). As the name suggests, middle-of-market aircraft are positioned in between the market segments served by narrow body (single-aisle) and wide body (twin-aisle) aircraft. This paper presents the findings of a study on the effect of anthropomorphic variability on economy class seating on middle-market aircraft currently in service. The study found that among 130 middle-market LOPAs, the mean seat pitch was greater for US airlines than for Asian airlines. Furthermore, the sampled Asian airlines had a higher preference …

Our approach is to analyze various scenarios to understand which …
The Effect Of Task Load, Automation Reliability, And Environment Complexity On Uav Supervisory Control Performance, Sarah M. Sherwood
The Effect Of Task Load, Automation Reliability, And Environment Complexity On Uav Supervisory Control Performance, Sarah M. Sherwood
Doctoral Dissertations and Master's Theses
Over the last decade, military unmanned aerial vehicles (UAVs) have experienced exponential growth and now comprise over 40% of military aircraft. However, since most military UAVs require multiple operators (usually an air vehicle operator, payload operator, and mission commander), the proliferation of UAVs has created a manpower burden within the U.S. military. Fortunately, simultaneous advances in UAV automation have enabled a switch from direct control to supervisory control; future UAV operators will no longer directly control a single UAV subsystem but, rather, will control multiple advanced, highly autonomous UAVs. However, research is needed to better understand operator performance in a …

Evaluation Of A Scientifically Developed Anesthesiology Handoff Protocol, Kristen Lise Welsh Webster
Doctoral Dissertations and Master's Theses
Communication failures have been cited as the leading cause of avoidable adverse events in healthcare. Specifically, within handoffs, these communication failures can cause error in the transfer of patient information. A multitude of factors can affect the transmission of patient information between providers including transactive memory, power distance, and conversational noise; however, literature suggests that the use of handoff protocols assist in improving communication and efficiency during handoffs. Studies regarding handoffs have typically centered on the content or delivery of the information during the handoff. To date, none have targeted the underlying mechanisms of the communication and their effects on …

Doctoral Dissertations and Master's Theses
Seat comfort has become increasingly important in today's society as we spend more time at consoles, instrument panels, or just online. However, seat comfort is hard to define and difficult to measure. Several measures both objective and subjective were used to evaluate seat comfort in commercially available average pilot seats. Three pilot seats, which had the same material and similar adjustments but different physical attributes, and a universal classroom seat, with different material and no adjustments, were compared by 20 volunteers using subjective and objective measures in a Latin square controlled repeated measures design.

Level Of Agreement In The Mental Models Of Human Factors Practitioners And Systems Engineers Working In Collaborative Teams, Jerry A. Gordon
Doctoral Dissertations and Master's Theses
Emerging research in complexity science recognizes traditional techniques for engineering systems do not always work for complex systems. Designing complex systems requires individuals to have knowledge of engineering as well as human performance. To this end, design efforts rely often on multi-disciplinary teams. While any two members of a design team may view the system design problem in vastly different manners, this study sought to identify a possible systemic effect on approach by the differing education and experience obtained by social practitioners, represented by human factors, and technical practitioners, represented by systems engineers. It further examined the impact of the …

Nurturing Systems Thinking: Developing A Framework Based On The Human Factors Analysis And Classification System (Hfacs) To Improve Systems Development Processes, Arjun Vijayanarayanan
Doctoral Dissertations and Master's Theses
Large systems engineering projects have an astonishingly high failure rate. The reasons hypothesized for such a high failure rate include the neglect of nonsalient system elements such as social and human or organizational aspects of systems. Social and human factors have long been known to be critical elements of systems that are frequently ignored (e.g., Goguen, 1994). Systems engineering processes can benefit and be improved by effective utilization of a framework that helps developers expand their attention and efforts beyond the salient aspects of the system and the development process. In the aviation field, the Human Factors Analysis and Classification …

Effect Of Sound Cue Frequency Filters On Front/Back Localization Performance For Three-Dimensional Verbal And Non-Verbal Warnings, Angelica A. Hernandez
Master's Theses - Daytona Beach
In aviation, as technology becomes more advanced and more demands are placed on the human operator, warnings have become an important part of display design. Although warnings have made a significant contribution to safety, problems still plague their design. Recent technological advances have been able to give sounds and warnings a three-dimensional quality (3D). This technology enables a person to perceive sound from any direction around the listener without having the sound physically come from that direction. Three-dimensional sounds have been shown to improve target acquisition and collision avoidance in flight (Oving & Bronkhorst, 1999), and may have other future …

The Effect Of Level Of Automation And Operator-To-Vehicle Ratio On Operator Workload And Performance In Future Uav Systems, Ryan J. Wasson
Master's Theses - Daytona Beach
The military intends to increase the number of UAVs in service while at the same time reducing the number of operators (Dixon, Wickens & Chang; 2004). To meet this demand, many of the current UAV operator functions will need to be automated. How automation is applied to modern systems is not fixed. Levels of automation exist along a continuum from fully manual to fully automatic. Two proposed levels of automation for future UAV systems are Management by Consent (MBC), where the operator selects the task to be executed, and Management by Exception (MBE), where the computer selects the task to …

A Study Of Fidelity Level And Task/Non-Task Based Testing Scenarios On The Effectiveness Of Usability Testing, Joshua R. Dolecal
Master's Theses - Daytona Beach
Advances in usability are directing developers towards creating a better and all around friendlier environment for users. Unlike when buying a physical product where you purchase it first and then experience its usability, web site usability is immediately present. So, if a site doesn't meet our needs, we as users, are quick to look elsewhere. Some research has suggested that fidelity makes no significant impact on users' ability to locate errors or problems in a web site. This paper is intends to investigate the interaction between fidelity and task vs. non-task user testing with regards to the types of problems …

An Analysis Of The Effects That Several Design Variables Have On The Accuracy And Precision Of Glass’ Delta And Hedges’ G, Joshua N. Dryer
Master's Theses - Daytona Beach
Effect size is the standardized effect that some treatment has on a sample of a population. In particular, Hedges' g and Glass delta are mean difference effect size estimators that are used to compute the effect sizes found in an experimental situation. A confidence interval is an interval placed around a point estimate that indicates the precision with which the point estimate can be made. This paper provides an explanation of the concept of effect size estimation and confidence interval calculation, the different methods that can be used to calculate effect sizes and confidence intervals, and applies these methods in …
The Search For The Opto-Kinetic Cervical Reflex And Reduced Roll Reversals In Pilots Viewing A 3-D Perspective Display, John Carl Faust
The Search For The Opto-Kinetic Cervical Reflex And Reduced Roll Reversals In Pilots Viewing A 3-D Perspective Display, John Carl Faust
Master's Theses - Daytona Beach
Pilots using conventional instrumentation can suffer spatial disorientation (SD) when unexpectedly forced to transition from visual flight to instrument flight during roll maneuvers. This simulator study was conducted to see if a 3-D perspective display could prevent this form of spatial disorientation by eliciting the opto-kinetic cervical reflex (OKCR), an instinctive postural response that humans use to maintain awareness of their spatial orientation. The current research found evidence of the OKCR in pilots viewing both a 3-D perspective display and an electronic attitude indicator. Pilots viewing a standard moving-horizon attitude indicator produced little or no OKCR response. However, pilots still …

Variations In Control And Display Gain In A First Control Order Compensatory Manual Tracking Task, Micah N. Morris
Variations In Control And Display Gain In A First Control Order Compensatory Manual Tracking Task, Micah N. Morris
Master's Theses - Daytona Beach
There exist many factors that contribute to the optimal manual control of a system by a human operator (HO). Two such variables include control gain and display gain. Of particular interest to the following experiment is the contribution of these two variables to the manual tracking performance of any HO conducting a compensatory tracking task while using a first control-order tracking system. Since the optimal level of control gain required for maximal manual control of a tracking device is system dependent, it may be expected that the same holds true of display gain. Regardless, it is the purpose of the …
