Visualization Methods For Communicating Unmanned Vehicle Plan Status, Kyle J. Behymer, Heath A. Ruff, Elizabeth M. Mersch, Gloria L. Calhoun, Sarah E. Spriggs

International Symposium on Aviation Psychology - 2015

In order to facilitate a single operator controlling multiple unmanned vehicles, numerous autonomous support tools are being considered. One such candidate tool monitors the situation and alerts the operator when a deviation from the vehicle’s plan has occurred. The goal of this research was to develop an effective visualization method for conveying plan deviations. Two interface formats were developed based on a review of the literature: a pie chart and a bar chart. Each format allows an operator to compare values for parameters that have different units, value ranges, and relative priority. Twelve participants were tested using a 2 (chart …

Design And Evaluation Of A Haptic Display For Flight Envelope Protection Systems, J. Ellerbroek, M.J.M. Rodriguez Y Martin, M.M. Van Paassen, M. Mulder

International Symposium on Aviation Psychology - 2015

This paper describes the design and initial evaluation of a haptic display that is aimed to complement a `hard’ flight envelope protection system. The evaluation mainly focused on usability of the presented haptic cues, and on the handling qualities of the stick with active feedback. Results are presented for two evaluations, concerning stall protection feedback and load factor protection feedback respectively. They show that while subjects are positive about the added information cue, and are able to correctly identify limiting actions, they are not consistently able to identify changes in the aircraft’s condition.

Detecting Structure In Activity Sequences: Exploring The Hot Hand Phenomenon, Taleri Hammack, John Flach, Joseph Houpt

International Symposium on Aviation Psychology - 2015

Can humans discriminate whether strings of events (e.g., shooting success in basketball) were generated by a random or constrained process (e.g., hot and cold streaks)? Conventional wisdom suggests that humans are not good at this discrimination. For example, Kahneman (2011) writes that “the hot hand is entirely in the eye of the beholders, who are consistently too quick to perceive order and causality in randomness. The hot hand is a massive and widespread cognitive illusion” (p. 117). Following from Cooper, Hammack, Lemasters, and Flach (2014), a series of Monte Carlo simulations and empirical experiments examined the abilities of both humans …

Airframe Parachute Knowledge And Deployment Scenarios: A Collegiate Perspective, Scott R. Winter, Robert C. Geske, Stephen Rice, Richard O. Fanjoy, Lauren Sperlak

International Symposium on Aviation Psychology - 2015

As airframe parachutes in general aviation aircraft become more popular, training is essential in fostering a willingness to use the system in the appropriate situation. Aviation decision-making literature suggests that individuals make choices based on experience and pattern matching, such as emergency situations and airframe parachute deployment scenarios. This led the researchers to investigate the knowledge and perspectives of collegiate pilots who train in aircraft equipped with airframe parachutes. Participants completed a surveyfocused on airframe parachute knowledge and scenario-based examples. Training experts were used to validate the parachute deployment scenarios used in the instrument. Responses indicate that pilots find aircraft …

The Federal Aviation Administration’s Human Factors Research and Engineering Division has strengthened the presence of human factors activities in NextGen products in the Human Systems Integration (HSI) and other Roadmaps. This paper will present the HSI Roadmap and explore NextGen human factors integration opportunities in tower operations. Opportunities have …

Consumer Trust Ratings After An Airline Accident: An Affective Perspective, Scott R. Winter, Stephen Rice, Ismael Cremer, Rian Mehta

International Symposium on Aviation Psychology - 2015

Fortunately airline accidents are rare; however when one occurs it usually results in widespread media attention. The purpose of this study was to examine how consumers’ trust ratings were impacted when one airline suffered an accident. The findings indicate that System Wide Trust (SWT) theory applies resulting in a trust reduction for all airlines, not just the accident airline. Affect was shown to act as a mediator in only three of the cases, which suggest that consumer’s responses may not be strongly influenced by emotions. Practical implications and limitations of this study are provided.

Anticipatorily Controlled Top-Down Processes Influence The Impact Of Coriolis Effects, Christine M. Talker, K. Wolfgang Kallus

International Symposium on Aviation Psychology - 2015

The impact of the vestibular-induced Coriolis illusion becomes apparent in spatial disorientation and symptoms of motion sickness. Empirical data indicated that anticipatory processes, evolved by experience, influence the sensation of Coriolis illusion. We measured subjective well-being and stress responses of 13 experienced pilots and 13 non-pilots in order to study the influence of anticipatorily controlled top-down attention on the impact of Coriolis effects and to examine the role of experience. Subjective data and psychophysiological data (EDA, ECG) were recorded, reflecting the underlying psychological processes involved. Participants distracted by doing a reaction test (experimental group) gave higher drowsiness ratings and higher …

Visual Search And Target Selection Using A Bounded Optimal Model Of State Estimation & Control, Brandon S. Perelman, Christopher W. Myers

International Symposium on Aviation Psychology - 2015

Visual attention and motor control are tightly coupled in domains requiring a human operator to interact with a visual interface. Here, we integrate a boundedly optimal visual attention model with two separate motor control models and compare the predictions made by these models against perceptual and motor data collected from human subjects engaged in a parafoveal detection task. The results indicate that humans use an optimal motor control policy limited by precision constraints – humans executed ballistic movements using near-optimal velocity (i.e., bang-bang control), but imprecision in those movements often caused participants to overshoot their targets, necessitating corrective action. Motor …

An Ecological Approach To The Supervisory Control Of Uav Swarms, Christian Fuchs, Clark Borst, Guido De Croon, Rene Van Paassen, Max Mulder

International Symposium on Aviation Psychology - 2015

Advances in miniaturized computer technology have made it possible for a single Unmanned Aerial Vehicle (UAV) to complete its mission autonomously. This also sparked interest in having swarms of UAVs that are cooperating as a team on a single mission. The level of automation involved in the control of UAVswarms will also change the role of the human operator. That is, instead of manually controlling the movements of the individual UAVs, the system operator will need to perform higher-level mission management tasks. However, most ground control stations are still tailored to the control of single UAVs by portraying raw flight …

Developing Quantitative Air Traffic Risk-Benefit Pathways For Class Delta Airports: Improving Small Tower Operations, Katherine A. Berry, Michael W. Sawyer, Jordan Hinson

International Symposium on Aviation Psychology - 2015

The primary responsibility of an Airport Traffic Control Tower (ATCT) controller is to prevent collisions between aircraft and other hazards on the surface and in the immediate vicinity. The safety service provided by controllers at towers with larger operations greatly exceeds the costs of establishing those towers. As the number of operations decreases, the costs of operating the tower may begin to outweigh the benefits of staffing the tower. Safety event reports describing instances where an ATCT controller provided a service that reduced the consequences of the event were collected. The reports were classified to identify latent factors, causal factors, …

Tactile Cueing Strategies To Convey Aircraft Motion Or Warn Of Collision, Ben D. Lawson, Roger C. Cholewiak, J. Christopher Brill, Angus H. Rupert, Linda-Brooke I. Thompson

International Symposium on Aviation Psychology - 2015

This report highlights five current vibrotactile display technologies for conveying aircraft motion or approach to obstacles or waypoints, including: 1) a simple on/off vibration cue that activates when a designated position is reached; 2) vibrations whose on-off pulse rate increases as the vehicle moves faster; 3) vibrations whose fundamental frequency rises to cue the approach of an object; 4) vibrations whose body site of spatial cueing signals self-motion in a manner analogous to tactile cues during sliding along the ground; 5) vibrations whose body site of cueing expands in a manner analogous to visual looming cues. The advantages and limitations …

Audiotactile Aids For Improving Pilot Situation Awareness, J. Christopher Brill, Ben D. Lawson, Angus H. Rupert

International Symposium on Aviation Psychology - 2015

Up to one-third of all aircraft mishaps are attributable to spatial disorientation (SD), costing lives and millions of dollars. One potential solution is to provide supplementary sensory cues to help improve pilots’ situation awareness (SA). Given existing demands on the pilot’s visual system, audition and touch present the greatest potential for success. However, accurate 3D audio perception may be problematic in noisy operational environments. To determine the effects, participants performed an azimuth cue localization task while listening to 90 dB helicopter noise. Cue modalities conditions included 3D audio, vibrotactile, and audiotactile. Accuracy was better and response times were significantly faster …

Expression Of The Nkcc2a Cotransporter In Mouse Central Nervous System, Katherine E. Fahy, James B. Lucot, Hayo Castrop, Mauricio Di Fulvio

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

Na-K-2Cl cotransporter 2A (NKCC2A), also known as the bumetanide-sensitive cotransporter 1 (BSC1), transports Na+, K+ and Cl- with a stoichiometry of 1:1:2. NKCC2A is considered a kidney specific cotransporter. It is abundantly expressed in apical membrane of the tubular cells in the thick ascending limb of the loop of Henle (TALH) and in the macula densa. However, NKCC2 has also been found at low levels in different cells, including insulin-secreting ones. This secondary active transporter uses the energy stored in the electrochemical gradients of Na and K maintained by the Na/K-ATPase located on the basolateral membrane of the TALH. The …

Assessment Of Knowledge And Attitudes On Latent Tuberculosis Treatment Acceptance In A Southwest Ohio Public Health Clinic, Ann M. Biedenharn

Master of Public Health Program Student Publications

Latent tuberculosis infection (LTBI), like active tuberculosis (TB) disease, disproportionately affects foreign-born persons living in the United States. Without treatment, those diagnosed with LTBI risk going into active disease and potentially becoming infectious. Determining any knowledge, attitudes, or social characteristics associated with a person’s decision to initiate LTBI treatment is significant for TB control. A logic model based on the Theory of Reasoned Action functioned as a guide to understanding the antecedents related to LTBI treatment acceptance. Participants enrolled in the study at the time of LTBI treatment offer in a Southwest Ohio public health TB clinic. An examination of …

Relactation In Emergencies, Ashley N. Franz

Master of Public Health Program Student Publications

Disaster situations in the United States are unique entities that require solutions which are well thought out, appropriate for the population and planned well in advance. Infant and young child feeding in emergencies is no exception. While in peacetime infants may be safely nourished with both breastmilk and infant formula, disaster situations often add a level of complexity to feeding with infant formula, including lack of access to potable water and ability to effectively sterilize feeding items. Such complexities, along with the important and undeniable fact that breastmilk is the ideal form of food for all babies (and especially in …

Decompression Illness In United States Air Force: High Risk Occupations, Jaime Rojas

Master of Public Health Program Student Publications

Introduction: Although the physics of decompression sickness (DCS) is well understood, an individual’s unique response to the bubble formation places the United States Air Force’s (USAF) Airmen and missions at risk. We identified 123 decompression sickness diagnoses in the USAF between the years 2005-2010. From these cases we attempted to identify an association between the disease and the two occupations that are routinely performing high-altitude duties, the U2 pilot and the hypobaric chamber technician. Methods: A Chi-squared analysis was performed to identify if DCS was associated with the high-altitude occupations, tobacco, or alcohol. Results: There association between DCS and U2 …

International Symposium on Aviation Psychology - 2015

N=60 commercial airline pilots holding valid ATPLs flew a manual ILS approach following a weather induced missed approach during a night mission in full flight simulators. Measures of subjective fatigue, sustained attention, and the NASA Taskload Index were collected before and after the mission. In addition, sleep history data were available covering three days prior to the simulator. Both subjective and objective measures of fatigue showed significant ascent over the three hours of the experimental procedure. While sleep history data and roster information were related to both the overall level of fatigue and to reaction times, pilots who experienced a …

Army Aviation Manned-Unmanned Teaming (Mum-T): Past, Present, And Future, Grant Taylor, Terry Turpin

International Symposium on Aviation Psychology - 2015

As the use of unmanned aircraft systems (UAS) in military operations has increased, so too have their capabilities. One recently developed capability is the ability to operate in conjunction with traditional manned aircraft through a process called manned-unmanned teaming (MUM-T), allowing manned aviators to benefit from the unique capabilities of UAS. This paper provides an introduction to the concept of MUM-T, describing the early stages of research and development, current MUM-T capabilities in fielded Army systems, and planned future development efforts to continue to advance the capability.

Optimizing Performance Of Trainees For Uas Manpower, Interface And Selection (Optumis): A Human Systems Integration (Hsi) Approach, Jennifer Pagan, Dr. Randy Astwood, Cdr Henry Phillips

International Symposium on Aviation Psychology - 2015

Unmanned Aerial System (UAS) operations research by Williams (2004) found that platforms which employ winged aviators (e.g., Predator) have shown higher mishaps than those that select operators that are nonpilots (e.g., Shadow). One explanation may be negative training transfer from manned to unmanned platforms as operators are separated from the aircraft, thus depriving them of a range of sensory cues (McCarley & Wickens, 2007). Another explanation for higher Predator mishaps may be associated with poor Ground Control Station (GCS) design. These varying explanations for differences in mishap rates across platforms indicate the need to address a number of Human System …

Follow-Up Examination Of Simulator-Based Training Effectiveness, Maxine Lubner, Andrew R. Dattel, Deb Henneberry, Sharon Devivo

International Symposium on Aviation Psychology - 2015

A descriptive examination of the effectiveness of a simulator-based training program for pilots was conducted. Of 55 students of varying backgrounds, but mostly with limited flight experience, 13 enrolled in an intensive, simulator-based flight training program. Within two years the remainder had enrolled in conventional collegiate flight training, supplemented with some simulator training. The students in the intensive program completed their FAA Private Pilot certificates in an average of 5 weeks (not including simulator time). Moreover, the intensive program group earned their private pilot’s certificate in statistically significantly fewer hours (M=46.03) than the conventional collegiate flight training group (M=76.06). The …

The Electrooculogram And A New Blink Detection Algorithm, Samantha L. Epling, Matt Middendorf, Michael Hoepf, Christina Gruenwald, Lucas Stork, Scott Galster

International Symposium on Aviation Psychology - 2015

Accurate and efficient real-time cognitive workload assessment has many important applications, and physiological monitoring has proven quite helpful with this assessment. One such physiological signal, the electrooculogram (EOG), can provide blink rate and blink duration measures. In a recent study, we developed and validated a robust blink detection algorithm based on the vertical EOG (VEOG). This algorithm does not require baseline data and is adaptive in the sense that it works for a wide variety of individuals without any experimenter adjustments. The performance of the algorithm is quantified using truth data based on video recordings. The algorithm produced blink rate …
