| Signal Detection Theory | 30 sept. 2026 | 00:01:39 | |
...and now for another Human Factors Minute!
Signal Detection Theory is a model for understanding decision accuracy in ambiguous circumstances developed in the 1950s as a response to WWII radar research and is used in domains ranging from psychology, medical diagnostics, and statistical decisions.
Detection theory explains an observer's ability to determine the presence or absence of a stimulus, based on how well they can differentiate the target from random input, referred to as noise. What qualifies as a signal and noise is context dependent.
Noise is anything that interferes with detection. For humans, noise is everywhere. Personal experience, expectations, physiological state among other factors affect the decision maker’s threshold to filter through internal and external sources of noise. In a life or death scenario someone may be more likely to detect faint stimuli than they would in a moment of safety, but they might also be more likely to over identify harmless stimuli as a threat.
A well adapted system demonstrates a strong ability to discern such information. A subject’s identification of the stimuli’s status falls into one of four categories:
-True positive
-False negative
-False alarm
-Correct rejection
In a real world scenario, a radar operator would be responsible for deciding if the radar screen is displaying electronic signals that represent a plane or random inputs.
Detection theory can be observed in memory recognition experiments or eyewitness identification. Witnesses tend to base their decisions on a perceived level of familiarity with the suspect. In this example, the signal is the familiar feeling generated by the known input, and the noise corresponds to a false feeling of familiarity from the new stimulus.

| A/B Testing | 20 sept. 2026 | 00:01:29 | |
...and now for another Human Factors Minute!
A/B testing is a randomized experimentation process in which two or more versions of a single variable, be that a web page or page feature, are shown to users to figure out which performs better. The “A” refers to the “control”—the original format and the “B” is a variation of that. It is also known as split testing because you split the sample of users where one half uses one version A, and the other half uses the “B” version. Say for example, you wanted to test out the effect of the location of a subscribe button on a website for new visitors. The current subscribe button is at the bottom of the webpage is “A” while the challenger B would be a button placed at the top of the webpage. You would then test these two versions of button webpage placement with a predetermined percentage of first-time site visitors. The metric would be the number of clicks the button gets.
A/B testing is useful because it eliminates all the guesswork out when designing a product and helps designers make data-informed decisions that can potentially increase user engagement, reduce bounce rates, minimize risk, and create engaging content.
Some fun facts: While A/B testing are most associated with websites and apps, the method is nearly 100 years old. Google first used A/B testing in the year 2000 and now they and other companies conducts over 10,000 A/B tests a year!

| HFETAG - HFE/HSI | 31 août 2026 | 00:02:01 | |
Did you know the The Department of Defense Human Factors Engineering Technical Advisory Group is composed of 19 sub Technical Advisory Groups? One of those is the HFE/HSI SubTAG. This SubTAG's area of interest includes DoD and service HSI policy, HSI initiatives (Army MANPRINT, Air Force IMPACTS, Navy HSI), interservice inconsistencies in the acquisition process, feedback of lessons learned from test results and field operations to human factors engineers, and the identification of problems during application of HSI tools, technologies, standards, or guidance. Industry/government, higher/lower staff echelon, and support relations are of prime interest. According to DOD Directive 5000.2, Human System Integration (HSI) is concerned with both the application of Human Factors Engineering (HFE) during weapon system acquisition and modification, and the prediction of HFE consequences on manpower, personnel, training, safety, and health/biomedical requirements. The purpose of this subgroup is to explore how policies, procedures, and practice can best facilitate HSI. The directive's emphasis is more on management and communication than on technology, more on acquisition than research and development, and more on the application of HSI tools than on the tools themselves. Typical topics of interest would include RFP preparation, source selection, design analysis, design reviews, interaction between staffs of different services/represented organizations, interaction between human factors engineers and other system engineers, review of contractor data submissions, test planning, evaluation or research products in the application environment, and coordinated research and development request activity.

| Affordances | 20 août 2026 | 00:01:32 | |
Affordances, coined by psychologist James Gibson in 1966, are detailed as what an environment offers to an individual. Further detailed later by computer interaction researcher Don Norman as, “A relationship between the properties of an object and the capabilities of the agent that determine just how the object could possibly be used” or, “action possibilities.” Affordances imply what interactions for users are possible in our everyday life, physically and digitally. Affordances generally exist within the following categories: False – Where the environment/object characteristics suggests and action may be taken where one does not exist, such as a button on an interface that does not work. Hidden – Where there is no obvious explanation on interaction so the individual must rely on previous experience or knowledge to engage with the interface, such as hovering over an icon on a webpage to see if it is an active link. Perceptible – Where the object/interface itself indicates what action possibilities are available and achievable, like a digital ordering menu at a restaurant that says “Place Order Here.” For User Interface design, here are some examples of how affordances are used in design: - Floppy disk icon affords saving data - Magnifying glass affords searching - Home icon affords returning to the home page - Plus icon affords being able to add an element This has been another Human Factors Minute Be sure to check out our main show at our official website: https://www.humanfactorscast.media Support us on these platforms to get access to the entire Human Factors Minute library:

| Galvanic Skin Response | 10 août 2026 | 00:01:47 | |
...And now for another Human Factors Minute.
Galvanic skin response, or GSR, is the measurement of change in the skin's electrical conductivity. This change comes as a result of increased sweat gland activity. When someone experiences emotional arousal, such as sadness, joy, or fear, there is also a change in sweat gland activity. The GSR measurement can be reflectivity of the intensity of an emotional state. To measure this, GSR electrodes are usually attached to the hand, which has the highest density of sweat glands in the body. A device is then used to record this data.
GSR data is often used by human-computer interaction researchers to measure cognitive load when users interact with interfaces. When a research participant becomes frustrated or stressed with a complex interface, their galvanic skin response increases. Researchers can use GSR to support surveys and interviews with participants, as it proves that the body had an emotional response. A researcher can then use the physiological data to quantitatively measure how intuitive and satisfying a user’s experience is. Researchers may also find GSR useful when paired with data reflecting other physiological changes, such as heart rate, respiration, or eye pupil dilation.
Besides HCI, GSR can be used in many other fields. It is well-known as being part of the controversial polygraph test, which assumes GSR response can determine whether someone is telling the truth. It can also be used to measure engagement, agitation, emotional arousal to entertainment and other forms of content. Overall, GSR reveals a part of an individual’s subconscious, as skin conductivity cannot be consciously regulated.

| The Multiple Oscillator model | 31 juil. 2026 | 00:01:06 | |
The Multiple Oscillator Model is a connectionist model that describes how we perceive time. An oscillator can be described as a pacemaker with a repetitive rhythm - like a swinging pendulum. The perception of an oscillator can provide the linear metric of time without one having to read a clock. This particular model describes time as being perceived through the feedback of multiple oscillators, each with a different frequency once they are triggered. It is believed that intervals in seconds can accurately be perceived when a set of oscillators coincide with one another. This model works as long as each sensory event triggers the oscillators to reset. However, it is unlikely that one could account for shorter intervals, like a few hundred milliseconds. The multiple oscillator model and other proposed time-perception theories are part of the larger picture in researching why we sometimes have an altered perception of time in different situations. There are a variety of human factors that go into time perception, and there is still much to learn.

| HFETAG - Controls & Displays | 20 juil. 2026 | 00:01:51 | |
Did you know the The Department of Defense Human Factors Engineering Technical Advisory Group is composed of 19 sub Technical Advisory Groups? One of those is the Controls and Displays SubTAG. This SubTAG aims to ensure that the development of advanced display and control systems for use by human operators is done consistent with the principles of human factors, with the intent of providing a means by which all DOD, NASA, and FAA personnel who are working in the area of displays and controls can maintain a high level of awareness of developments being made in controls and displays. This SubTAG defines displays as visual, audio, tactile, and other devices, which can be used to provide information to a human operator. Whereas controls include anything that allows for direct manipulation, neurological interfaces, ocular metrics, and voice. While there may be some overlap between areas of interest of this SubTAG and other organizations, the Controls and Displays SubTAG freely exchanges information with other organizations and attempts to cooperate in every way possible to mitigate overalap. The Controls and Displays subtag serves as a forum for the exchange of ideas and information about the latest work in displays and controls and provides support of research or development efforts which would be beyond the capacity of any individual sponsor. Additionally, this group will assist with the standardization of display and control characteristics where needed.

| Behavioral Theory of Timing and Poisson Processes | 30 juin 2026 | 00:01:18 | |
The Behavioral Theory of Timing comes to us from Peter Killeen and Gregor Fetterman in 1988. The general idea is that the reinforcement of behaviors generates knowledge of the average amount of time between reinforcement. This knowledge is what sets our internal clock, which then tells us when to perform the behavior. The transitions between behaviors are considered a Poisson Process. A Poisson Process is a probability concept that can be applied to many real-world situations. For something to qualify as a Poisson Process, events must be independent of each other, the average rate of events is constant, and two events cannot occur at the same time. For example, we can think of how often a website will go down in a given time period or how often customers will call a help center. Back to our Behavioral Theory of Timing! This model of timing is a formalization of the concept that behavior is the mediator of temporal control, linking it to the behaviorist movement in psychology that began in the early 1900s. Like other theories of timing, the Behavioral Theory of Timing posits that we have a pacemaker-accumulator system, or that an oscillator of some type generates pulses that are summed by a hypothetical "accumulator." Variations in timing accuracy are explained as errors from the pacemaker or accumulator.

| Virtual Fit Multivariate Anthropometric Tool | 20 juin 2026 | 00:01:35 | |
...and now for another Human Factors Minute! The Virtual Fit Multivariate Anthropometric Tool was developed by HFES in collaboration with Penn State University to make multivariate accommodation estimates for North American users. The tool works by calculating the percent of the population that would be able to be accommodated by a specific design, and it also allows specification based on gender proportion. It uses a multivariate analysis approach, which is based on the idea that designs can fail to fit users in multiple ways. A product may be designed too short for one person, or too narrow, but this failure to fit in both situations may not always be shared by the same person. Designs may use multiple anthropometric measures. For example, a chair can be measured in several ways such as seat depth, seat width, and seat height. This tool allows designers and ergonomists to check their measurements for the highest percent accommodation that they intend. When considering a real world use case of a standing workstation desk, the tool can be used by entering the dimensions for the product into The Virtual Fit spreadsheet. First, the estimated gender proportion of users is populated into the tool. Then, when the height of the surface desk is entered into the tool, the designer or ergonomist will be given a percent of the population that will be appropriately accommodated by this dimension. You can use the Virtual Fit Tool for free via the Penn State website (https://www.openlab.psu.edu/tools/vft/). This has been another Human Factors Minute!

| Heart Rate Monitoring | 20 mai 2026 | 00:01:43 | |
Heart rate monitoring is often used to gather real-time data from a user’s physiological response while they are performing tasks on a product or system. This is an important biometric & neuro-measurement tool because it senses unconscious changes in a user’s stress, workload, and drowsiness. Since mental processing like emotional reactions and decision-making happen unconsciously, it offers more insight to how a user’s body is responding to a given situation. In user studies, if a participant is having trouble completing a task, they might become more emotionally aroused and stressed. Even if they verbally express that they aren’t having much difficulty, heart rate monitoring can provide insight into the actual physiological response during various tasks. There are a few main methods of gathering data from heart rate monitoring: A PPG, or photoplethysmogram, has an optical sensor which measures discoloration of a user’s skin as blood runs through capillaries and arteries with each heartbeat. The most common PPGs are usually fingertip sensors or wrist bracelets and they are low-cost, not very intrusive, and easy to set up. However, they have more “noise” and “waveform morphology” variation than the other method, electrocardiogram. Both ECG and EKG reference an electrocardiogram, which directly measures the heart’s electrical activation. It creates different waveform data than a PPG, but it’s the most accurate for real-time heart monitoring. A wearable EKG chest monitor is the most accurate way outside of a hospital setting to gather a user’s heart rate data. The downside to these devices is that they’re typically expensive and more intrusive than a PPG.

| The Diffusion Model | 10 mai 2026 | 00:01:31 | |
The diffusion model is a psychological model of how we process a single-stage decision when there is a simple choice between two options. This is beneficial both in human decision making as it allows for a conclusion to potentially be reached earlier than in complex decision making. One of the key distinctions of diffusion models is that they are dynamic - able to describe the evolution of a person’s preferences over time. When discussed in terms of cognition, diffusion modeling is the mathematical representation of decision field theory, an approach to human decision making, which aims to describe how people make decisions rather than prescribe what decisions people should or ought to make. Cognitive scientists have been using this model to measure performance in tasks ranging from sensory detection and perceptual discrimination to memory recognition and categorization. In neuroscience, these models have demonstrated an ability to account for behavioral decision making for which traditional models used in economics and psychology cannot. Successful implementation of diffusion models in cognition and neuroscience, demonstrate that they may be a key in providing a bridge between neural models of sensory-motor tasks and behavioral models of complex-cognitive tasks.

| HFETAG - Standardization | 30 avr. 2026 | 00:01:27 | |
Did you know the The Department of Defense Human Factors Engineering Technical Advisory Group is composed of 19 sub Technical Advisory Groups? One of those is the Human Factors Standardization (HFS) SubTAG. This SubTAG aims to identify programs and initiatives that are needed within the Department of Defense, specifically within Human Factors Standardization Area of Consideration (HFAC), other government lead standardization activities, and offices of primary record. The group's goal is also to provide advisory support to ensure successful coordinated efforts in implementing planned Human Factors Standardization. Avoiding duplication among DoD standardization is a critical function of this group as duplicated standards may lead to conflicting guidance. Lastly, this group aims to maximize and enhance the exchange of standardization information between the DoD human factors community and other government, non-government standards bodies, and other technical societies and industry groups. Much of this group's work includes identifying problems and opportunities on standardization activities, suggesting proposed actions to address the problems and exploiting opportunities for government-industry cooperation in resolving them. They also work to identifiy effective and efficient means of using standards in acquisition programs.

| OSHA Standard 1910 | 20 avr. 2026 | 00:01:17 | |
The Occupational Safety and Health Administration protects millions of workers through a labor code of federal regulations. OSHA 1910 ensures the adoption and extension of legal standards, creating general workplace safety requirements that apply to all industries. OSHA 1910 establishes compliance duties, air contaminant provisions, rules for walking and working surfaces, hazardous materials, personal protective equipment, first aid, emergency planning, and fire protection. Combined, these measures can increase workplace safety with dramatic effect. Since its implementation, OSHA has reduced workplace injuries and deaths by 50%. Human factors and ergonomics are at the heart of these life saving safety regulations. For instance they play a key role in a company’s policies, programs, and procedures, along with the physical design of the workplace environments. Additionally, Human Factors plays an important part in establishing training programs for worker competency and skill. Ergonomics can also contribute to the processes and procedures used to evaluate work practices that may cause long-term harm to a worker’s body. To discover more ways that human factors and ergonomics shape occupational safety policy, go to www.osha.gov.

| Scalar Expectancy Theory | 10 avr. 2026 | 00:01:45 | |
...and now for another Human Factors Minute!
Scalar Expectancy Theory, or SET, is an important model of animal timing behavior credited to John Gibbon in the late 1900s. The idea of SET is that animals have an internal clock and particular memory and decision-making processes, which explains why their behavior can be temporally controlled using fixed-interval reinforcement. The scalar part of SET comes from how animals compare the current time (held in their working memory) to the expected time (held in their reference memory). When the ratio is small enough, the animal performs the behavior. When the ratio is big enough, the animal stops doing the behavior. This ratio allows for the observation that animal timing accuracy is relative to the size of the interval being timed.
Although Gibbon’s theory was intended to apply only to animals, John Wearden claimed that SET could also be applied to humans. However, human behavior has much more variability than animal behavior does, mostly due to our attentional allocation, so this application is somewhat debated.
While SET was one of the first models of timing, it is not the only one: there are many alternative models of timing, some based on SET and some completely different. When using SET, it is important to keep in mind that it might not work for all durations, and some psychologists argue that it is inconsistent when it comes to explaining the location of temporal indifference point in temporal bisection procedure.

| Neuroergonomics | 28 févr. 2026 | 00:01:23 | |
...and now for another Human Factors Minute!
Neuroergonomics is the study of effectively apply state-of-the-art methods and theories from neuroscience to understand how the brain works in everyday life.
Traditional ergonomic studies rely predominantly on psychological explanations to address human factors issues such as: work performance, operational safety, and workplace-related risks .
Neuroergonomics, in contrast, addresses the biological substrates of ergonomic concerns, with an emphasis on the role of the human nervous system.
The goal of combining neuroscience with Human Factors (and Ergonomics) is to use the discoveries of the human brain and physiological functioning both to inform the design of technologies in the workplace and home, and to provide new training methods that enhance performance, expand capabilities, and optimize the fit between people and technology.
Findings obtained in work-defined settings often inform and challenge our understanding of what work means in terms of neural mechanisms.
Research in the neuroergonomics field has become more prevalent with the emergence of noninvasive techniques for monitoring human brain function that can be used to study various aspects of human behavior in relation to technology and work, including mental workload, visual attention, working memory, motor control, human-automation interaction, and adaptive automation.

| Electroencephlogram | 20 févr. 2026 | 00:01:14 | |
...and now for another Human Factors Minute!
An electroencephlogram, or EEG, is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. The device works by placing electrodes consisting of small metal discs with thin wires are pasted onto the participant's scalp. The electrodes detect tiny electrical charges that result from the activity in brain cells. The charges are amplified and appear as a graph on a computer screen, or as a recording that may be printed out on paper.
In Human Factors, EEGs are used typically to measure performance with respect to mental fatigue, mental workload, mental effort, visual fatigue, emotion, and stress.Many studies in human factors focus on evaluating an individual’s mental states while operating a vehicle, however there are plenty of other practical applications for using an EEG.
Outside of Human Factors, The EEG can be used used to evaluate several types of brain disorders, diagnose other disorders that influence brain activity, determine the overall electrical activity of the brain, and to monitor blood flow in the brain during surgical procedures.

| The Spectral Model | 31 janv. 2026 | 00:01:03 | |
...and now for another Human Factors Minute!
The Spectral Model is a model of one type of circuit within an animal or robot’s larger temporal organization.
It describes a mechanism for inhibiting the urge to move on too soon from an expected outcome by learning to wait for something that is expected by discounting expected nonoccurrences until the expected arrival of the goal object.
If the goal object does not appear after a certain amount of time, then the unexpected nonoccurrence of the goal can be processed and responded to appropriately.
This timing mechanism is important for the survival of animals and humans, especially those who seek out novel experiences, and for robots who will need to move and operate in environments that may have unexpected events.
We can think about when we are waiting for a friend to show up to lunch: after a certain amount of waiting past the designated meeting time, we might text or call our friend to get a status update.
The Spectral Model helps us to know when to continue waiting and when to take action.

| Vigilance | 10 janv. 2026 | 00:01:39 | |
...and now for another Human Factors Minute!
Vigilance is the action or state of keeping careful watch for possible danger or difficulties. The issue with this is that as automation is becoming increasingly more prevalent within our society humans are having to switch from the active role of operator to the passive role of monitor.
Human Factors research has identified many issues with requiring humans to do vigilance tasks as they are highly stressful on individuals because of their substantial demand on information processing resources. One reason for this is individuals need to constantly use working memory to distinguish what a threating detection is compared to a non-threatening detection.
Additionally, many experiments have measured workload during vigilance tasks. The results show that vigilance tasks carry high workload and are cognitively demanding. It is also found that vigilance decrement steadily increases as workload increases over time. Other studies show that there is a reduction in cerebral flow during vigilance tasks which provides physiological evidence that performance capabilities decrease during vigilance tasks.
Research has investigated the high stress that results from vigilance tasks. Data indicates that increases in epinephrine and norepinephrine, as well as self-reports of various experiments showing vigilance tasks cause individuals to disengage from the task and experience distress and worry.

| Perception of Time | 20 déc. 2025 | 00:01:42 | |
...and now for another Human Factors Minute!
With so many theoretical models for how we perceive time, researchers have started comparing the different models. This emphasizes that we still have much to learn about how we perceive time in the real world and use that perception to interact with our environment.
Recent research tells us that time perception involves a large neural network throughout the brain; there is no specific structure that controls it.
In general, our understanding is that our perception of time is a combination of a variety of factors such as attention, arousal, emotions, and environmental cues.
Time can appear to move faster if we are in a positive state and have a high approach motivation (the desire and drive to do something) or find activities so enjoyable and immersive that time seems to pass by faster than usual (sometimes referred to as a “flow” state)
Conversely, focusing our attention on something can also make time seem to move slower. When the possibility of a reward is present, stimuli are perceived as lasting longer than when there is little or no prospective reward. These results seemed to indicate that if a stimulus is associated with a reward, it becomes more salient, grabbing more of our attention and thus distorting how long we perceive it to last.
Time can also seem to move slower if we experience awe (likely from feeling more present and “in the moment”) or fear (possibly so that we have more time to prepare to react to fear-inducing stimuli).
Our experience of time is also influenced by cues from our bodies. Visual input, body movements, and information we receive from our tissues are connected to time perception, leading to what is called the embodied perspective of time perception in humans, which tells us that our brain’s interpretation of signals throughout our body is a crucial element of how we perceive time.

| Universal Design Heuristics | 10 nov. 2025 | 00:01:39 | |
...and now for another Human Factors Minute!
The probability of developing products and environments that are accessible for everyone lies within the concept of universal design. There are seven principles of universal design that serve as a foundation for designers and Human Factors practitioners that help make usable interfaces for all people no matter what age, technical expertise, or physical ability.
Equitable use, states that usable and accessible design is provided for people with a wide range of abilities.
Flexibility in use, aims to accommodate to user’s preferences and abilities.
Simple and intuitive use, seeks to create easy-to-understand design solutions for a variety of users who all possess different knowledge, experience, language abilities, and more.
Perceptible information, states that design solutions portray information clearly and effectively to the user.
Tolerance for error, promotes design that minimizes hazards resulting from user error.
Low physical effort, asks designers to develop designs that maximize comfort and minimize the discomfort that can result from too much physical exertion or unnatural body positioning.
Lastly, size and space for approach and use, states that users are provided with appropriate size and space for approach when interacting with a design.
Following the set of principles listed above can aid in promoting inclusive design to all users.

| INCOSE Systems Engineering Certifications | 31 oct. 2025 | 00:01:58 | |
...and now for another Human Factors Minute!
The International Council on Systems Engineering (INCOSE) is designed to connect systems engineering professionals with professional development opportunities in the interest of developing the global community of systems engineers and systems approaches to problems. They offer three types of certification for systems engineers: Associate, Certified, and Expert Systems Engineering Professional certification.
The associate (or ASEP) certification is meant for systems engineers just beginning to practice, such as junior systems engineers. Applicants will have “book knowledge” but no significant field experience yet.
For practicing systems engineers with more than 5 years of professional systems engineering experience, there is the certified level or CSEP. Applicants are self-sufficient, capable of carrying out systems engineering tasks in a variety of work situations, and capable of practicing in a broad range of domains including military systems acquisition and development, commercial product engineering, and public infrastructure engineering.
Finally, the expert certification or ESEP is for systems engineering professionals with recognized accomplishments in the field and at least 20 years of systems engineering experience. Applicants should have substantial experience in performing and leading systems engineering, such as program managers or chief systems engineers. Individuals should be experts in some aspects of systems engineering and able to perform adequately in many. This is the person others seek with specific, challenging, technical questions.
To obtain certification, ASEPs and CSEPs must complete a knowledge examination. CSEPs and ESEPs must provide references, with ESEPs completing a phone interview instead of an exam.
INCOSE certifications are valuable at any level and help set you apart from other job applicants by demonstrating your proficiency, dedication to your work, interest in ongoing professional development, and contributions to the systems engineering community.

| Human Factors of the Titanic | 30 sept. 2025 | 00:01:14 | |
...and now for another Human Factors Minute!
According to the granddaughter of the second officer aboard the Titanic, Charles Lightoller, The Titanic sank from human error. A new steering system led to a mistake by the steersman, into going "hard a port" instead of "hard a starboard" and straight into the iceberg instead of away from it.
According to the second officer's ancestor, a Charles Lightoller was the most senior officer to survive. He kept the secret from two separate inquiries because, according to his granddaughter, he saw it as his duty to protect the White Star Line from bankruptcy. He only told his wife the truth. His family kept it secret after his death to protect his reputation. He was a twice decorated war hero.
To make matter's worse, the chairman of the White Star Line, owner of the Titanic, ordered the ship to keep sailing. If they had stayed still as the captain had wanted, the ship would have taken hours to sink. Long enough to rescue everyone aboard. Instead, 1500 people died.

| Visibility and Lighting | 20 août 2025 | 00:01:16 | |
...and now for another Human Factors Minute!
In order for people to recognize and avoid dangerous conditions, they must be see the hazard.
Adequate illumination is critical for people to detect and identify hazards in time to avoid them. We measure the illumination and reflectivity of objects to determine their relative contrast, and the resulting visibility.
Our eyes handle a huge range of light visibility, in part by using two types of receptors: rods, which work well under low light conditions, and cones that work best under bright conditions.
In low light conditions, such as the outer edges of a headlight or work light beam, brightness contrast is what matters most.
This is because the rods, which detect very low levels of light, only come in one model, whereas cones come in three models. Having three different types of cones allows us to differentiate colors, and having only one type of rods leaves us in a black and white world.
In the case of safety and forensics, establishing visibility is only the first step. The follow up question is always, “when was this object noticeable”.

| Virtual Manufacturing and Response Surface Methodology | 31 juil. 2025 | 00:01:06 | |
...and now for another Human Factors Minute!
Virtual manufacturing and response surface methodology (VMRSM) is a method in ergonomics to use computerized tools and statistical analysis for workstation design.
Computerized tools help assist and enable an individual to simulate an evaluate a large mnumber of design configurations with respect to multiple performance measures.
Many of the tools available have the capability to model a workstation, but fail to model the interaction a user may have with a given workspace.
By combining the virtual modeling tools with an analysis by the ergonomist, human performance and ergonomic needs can be assessed to design these workstations.
The advantage of this method is that many computer tools are defined by metrics (like height, length, depth) and this frees up the analyst to focus on workflow, rather than specific parameters.

| Hearing and Sound in Aviation | 10 juil. 2025 | 00:01:19 | |
...and now for another Human Factors Minute!
Hearing has a much greater impact on performance than most people realize.
Modern aircraft designs put high demands on vision as the primary sense for information gathering, but such designs can lead to increased attentional demands that have the potential to decrease situational awareness.
To compensate, sound has become more important for delivering information or to divert a pilot’s attention to an area that needs monitoring.
At a very basic level, the ability to hear a signal will affect a pilot’s ability to respond to that signal. A signal could be missed because of physical problems related to the ear or because of environmental issues such as noise.
In addition to signal interference, noise associated with flight can cause physiological and/or psychological problems that can degrade performance.
The effects of noise on performance are complex. However, from an operational point of view, one of the most important issues is how noise affects attention. A number of studies have explored this issue.
Findings demonstrated that noise tends to decrease the ability to share attention between several concurrent tasks, especially when the tasks must be performed for extended periods of time.

| HFESTG - Surface Transportation | 10 juin 2025 | 00:02:06 | |
...and now for another Human Factors Minute! Did you know that the Human Factors and Ergonomics Society has 24 technical groups that are concerned with the human factors aspects of specific application areas?
One of those is the The Surface Transportation Technical Group (STTG)
This technical group provides a forum for people involved or interested in human factors to exchange information, methodologies, and ideas that are being developed and/or applied in the international surface transportation field.
The TG’s interest encompasses numerous modes for transporting humans and resources: passenger, commercial, and military vehicles, both on- and off-road; mass transit; maritime transportation; rail transit, including
Vessel Traffic Services (VTS); pedestrian and bicycle traffic; and highway and infrastructure systems. In essence, surface transportation refers to all forms of transit outside the aerospace sector.
Members of the Surface Transportation Technical Group recognize that the human operator is an integral component of a system (comprised of the operator, the surface vehicle, and the environment), just as the pilot is an integral component of the aircraft system. Therefore, the same effort that goes into designing and developing the vehicle and its infrastructure must be put into optimizing the behavior and performance of the operator.
As the performance capabilities of ground, rail, and waterbased vehicles become more advanced, accompanied by equal advances in the complexity of the operating environments, action must be take to ensure that vehicle handlers are able to perform their tasks with minimal errors and maximum comfort.
In addition to focusing upon the relationship between operators and their vehicles, members of the STTG are concerned with the behavior and performance of others who interact with these vehicles, including passengers, pedestrians, service personnel, etc. Furthermore, as the Information Age leads to technological developments that can enhance the safety and efficiency of transportation systems, STTG members are becoming more and more interested in the effects of infrastructure development (e.g., highways, traffic control devices, traffic management centers, etc.) on vehicle operators.

| Federation of European Ergonomics Societies Ergonomics in and for Europe | 20 mai 2025 | 00:01:39 | |
...and now for another Human Factors Minute!
The Federation of the European Ergonomics Societies also known as FEES mission is to enhance the recognition of ergonomics contributing to economic development, to quality of life, to health and safety at work, and to social progress in European Countries.
FEES is a network of the ergonomics societies in the various countries in Europe according to the description by the International Ergonomics Association (IEA) of IEA Networks. Members are ergonomics societies, not individuals. All ergonomics societies in Europe can be a member of FEES - inside the European Union landscape, but also beyond.
Objectives
Benefits to be FEES member:
to support the development of ergonomics in Europe
to influence the European Union (programs, legislation, etc.)
to develop interesting issues of mutual usage
and more
FEES supports - under the umbrella of the IEA - the development of ergonomics issues specifically related with the European region by:
enhancing mutual communication between various European ergonomics societies,
encouraging and facilitating contact and exchanges between ergonomists (educators, researchers and/or practitioners),
assisting in the organisation of European conferences about evolving ergonomics, in cooperation with the national societies.
