...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!Be sure to check out our main show at our official website: https://www.humanfactorscast.mediaSupport us on these platforms to get access to the entire Human Factors Minute library:Patreon: https://www.patreon.com/humanfactorscastBuy us a coffee: https://www.buymeacoffee.com/hfactorspodcastJoin us on Discord:https://go.humanfactorscast.media/DiscordFollow us:Human Factors Cast Merchandise Store: https://www.humanfactorscast.media/p/Store/Follow us on Twitch: https://twitch.tv/HumanFactorsCastFollow us on YouTube: https://www.youtube.com/HumanFactorsCastFollow us on LinkedIn: https://www.linkedin.com/company/humanfactorscastFollow us on Twitter: https://www.twitter.com/HFactorsPodcastFollow us on Facebook: https://www.facebook.com/HumanFactorsCastResources:Music by Kevin McLeod: https://incompetech.com/music/royalty-free/Mentioned in this episode:Support us on Patreon for access to the full library of Human Factors Minutehttps://www.patreon.com/humanfactorscast

...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.

...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.

...and now for another Human Factors Minute! Association for Computing Machinery's Special Interest Group on Computer Human Interaction (or ACM SIGCHI) is an international society for professionals, academics and students who are interested in human-technology and human-computer interaction. Through over 20 sponsored and over 40 in-cooperation conferences, publications, web sites, and other services they provide several forums for discussion. SIGCHI also offers workshops and outreach, and promotes informal access to a wide range of individuals and organizations involved in HCI. ACM SIGCHI facilitates an environment where its members can invent and develop novel technologies and tools, explore how technology impacts people’s lives, inform public policy, and design new interaction techniques and interfaces. Overall, the mission of ACM SIGCHI is to support the professional growth of its members who are interested in how people interact with technologies and how technology changes society.

...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. This has been another Human Factors Minute!
