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...

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 th...

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...

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...

...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...

...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...

...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...

...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. ...

...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...

...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 miss...
