To assess the fit between a person and the used technology, human factors specialists or ergonomists consider the job (activity) being done and the demands on the user; the equipment used (its size, shape, and how appropriate it is for the task), and the information used (how it is presented, accessed, and changed).

Etymology

The term ''ergonomics'' (from the

used the word in his 1857 article (The Outline of Ergonomics; i.e. Science of Work, Based on the Truths Taken from the Natural Science). The French scholar Jean-Gustave Courcelle-Seneuil, apparently without knowledge of Jastrzębowski's article, used the word with a slightly different meaning in 1858. The introduction of the term to the English lexicon is widely attributed to British psychologist
Hywel Murrell Hywel Murrell (1908 – 21 January 1984) was a British psychologist who introduced the term "ergonomics" to the English dictionary, created the first ergonomics department in British industry, and wrote the first British textbook on ergonomics. H ...

Domains of specialization

Ergonomics comprise three main fields of research: physical, cognitive, and organizational ergonomics. There are many specializations within these broad categories. Specializations in the field of physical ergonomics may include visual ergonomics. Specializations within the field of cognitive ergonomics may include usability,
human–computer interaction Human–computer interaction (HCI) is research in the design and the use of computer technology, which focuses on the interfaces between people (users) and computers. HCI researchers observe the ways humans interact with computers and design tec ...
, and user experience engineering. Some specializations may cut across these domains: ''Environmental ergonomics'' is concerned with human interaction with the environment as characterized by climate, temperature, pressure, vibration, light. The emerging field of human factors in highway safety uses human factor principles to understand the actions and capabilities of road users – car and truck drivers, pedestrians, cyclists, etc. – and use this knowledge to design roads and streets to reduce traffic collisions. Driver error is listed as a contributing factor in 44% of fatal collisions in the United States, so a topic of particular interest is how road users gather and process information about the road and its environment, and how to assist them to make the appropriate decision. New terms are being generated all the time. For instance, "user trial engineer" may refer to a human factors engineering professional who specializes in user trials. Although the names change, human factors professionals apply an understanding of human factors to the design of equipment, systems and working methods to improve comfort, health, safety, and productivity.

. One of the most prevalent types of work-related injuries is musculoskeletal disorder. Work-related musculoskeletal disorders (WRMDs) result in persistent pain, loss of functional capacity and work disability, but their initial diagnosis is difficult because they are mainly based on complaints of pain and other symptoms. Every year, 1.8 million U.S. workers experience WRMDs and nearly 600,000 of the injuries are serious enough to cause workers to miss work. Certain jobs or work conditions cause a higher rate of worker complaints of undue strain, localized fatigue, discomfort, or pain that does not go away after overnight rest. These types of jobs are often those involving activities such as repetitive and forceful exertions; frequent, heavy, or overhead lifts; awkward work positions; or use of vibrating equipment. The Occupational Safety and Health Administration (OSHA) has found substantial evidence that ergonomics programs can cut workers' compensation costs, increase productivity and decrease employee turnover. Mitigation solutions can include both short term and long-term solutions. Short and long-term solutions involve awareness training, positioning of the body, furniture and equipment and ergonomic exercises. Sit-stand stations and computer accessories that provide soft surfaces for resting the palm as well as split keyboards are recommended. Additionally, resources within the HR department can be allocated to provide assessments to employees to ensure the above criteria are met. Therefore, it is important to gather data to identify jobs or work conditions that are most problematic, using sources such as injury and illness logs, medical records, and job analyses. Innovative workstations that are being tested include sit-stand desks, height adjustable desk, treadmill desks, pedal devices and cycle ergometers. In multiple studies these new workstations resulted in decreased waist circumference and improved psychological well-being. However a significant number of additional studies have seen no marked improvement in health outcomes. With the emergence of

Cognitive ergonomics

Cognitive ergonomics is concerned with mental processes, such as perception, emotion, memory, reasoning, and motor response, as they affect interactions among humans and other elements of a system. (Relevant topics include mental workload, decision-making, skilled performance, human reliability, work stress and training as these may relate to human–system and

History


Ancient societies

Some have stated that human ergonomics began with ''Australopithecus prometheus'' (also known as “little foot”), a primate who created handheld tools out of different types of stone, clearly distinguishing between tools based on their ability to perform designated tasks. The foundations of the science of ergonomics appear to have been laid within the context of the culture of

Bernardino Ramazzini was one of the first people to systematically study the illness that resulted from work earning himself the nickname “father of occupational medicine”. In the late 1600s and early 1700s Ramazzini visited many worksites where he documented the movements of laborers and spoke to them about their ailments. He then published “De Morbis Artificum Diatriba” (Latin for Diseases of Workers) which detailed occupations, common illnesses, remedies. In the 19th century,

and Vladimir Nikolayevich Myasishchev criticised Taylorism. Bekhterev argued that "The ultimate ideal of the labour problem is not in it aylorism but is in such organisation of the labour process that would yield a maximum of efficiency coupled with a minimum of health hazards, absence of fatigue and a guarantee of the sound health and all round personal development of the working people." Myasishchev rejected Frederick Taylor's proposal to turn man into a machine. Dull monotonous work was a temporary necessity until a corresponding machine can be developed. He also went on to suggest a new discipline of "ergology" to study work as an integral part of the re-organisation of work. The concept was taken up by Myasishchev's mentor, Bekhterev, in his final report on the conference, merely changing the name to "ergonology"

. It was no longer possible to adopt the Tayloristic principle of matching individuals to preexisting jobs. Now the design of equipment had to take into account human limitations and take advantage of human capabilities. The decision-making, attention, situational awareness and hand-eye coordination of the machine's operator became key in the success or failure of a task. There was substantial research conducted to determine the human capabilities and limitations that had to be accomplished. A lot of this research took off where the aeromedical research between the wars had left off. An example of this is the study done by Fitts and Jones (1947), who studied the most effective configuration of control knobs to be used in aircraft cockpits. Much of this research transcended into other equipment with the aim of making the controls and displays easier for the operators to use. The entry of the terms "human factors" and "ergonomics" into the modern lexicon date from this period. It was observed that fully functional aircraft flown by the best-trained pilots, still crashed.

Concurrently, a lot of opportunities started opening up in the civilian industry. The focus shifted from research to participation through advice to engineers in the design of equipment. After 1965, the period saw a maturation of the discipline. The field has expanded with the development of the computer and computer applications. The

Sedentary workplace

Contemporary offices did not exist until the 1830s, with Wojciech Jastrzębowsk's seminal book on MSDergonomics following in 1857 and the first published study of posture appearing in 1955. As the American workforce began to shift towards sedentary employment, the prevalence of MSD/cognitive issues/ etc..began to rise. In 1900, 41% of the US workforce was employed in agriculture but by 2000 that had dropped to 1.9% This coincides with an increase in growth in desk-based employment (25% of all employment in 2000) and the surveillance of non-fatal workplace injuries by OSHA and Bureau of Labor Statistics in 1971. 0–1.5 and occurs in a sitting or reclining position. Adults older than 50 years report spending more time sedentary and for adults older than 65 years this is often 80% of their awake time. Multiple studies show a dose-response relationship between sedentary time and all-cause mortality with an increase of 3% mortality per additional sedentary hour each day. High quantities of sedentary time without breaks is correlated to higher risk of chronic disease, obesity, cardiovascular disease, type 2 diabetes and cancer. Currently, there is a large proportion of the overall workforce who is employed in low physical activity occupations. Sedentary behavior, such as spending long periods of time in seated positions poses a serious threat for injuries and additional health risks.Canadian Centre for Occupational Health. (2019, March 15). (none). Retrieved February, 2019, from https://www.ccohs.ca/oshanswers/ergonomics/sitting/sitting_overview.html Unfortunately, even though some workplaces make an effort to provide a well designed environment for sedentary employees, any employee who is performing large amounts of sitting will likely experience discomfort. There are existing conditions that would predispose both individuals and populations to an increase in prevalence of living sedentary lifestyles, including: socioeconomic determinants, education levels, occupation, living environment, age (as mentioned above) and more. A study published by the Iranian Journal of Public Health examined socioeconomic factors and sedentary lifestyle effects for individuals in a working community. The study concluded that individuals who reported living in low income environments were more inclined to living sedentary behavior compared to those who reported being of high socioeconomic status. Individuals who achieve less education are also considered to be a high risk group to partake in sedentary lifestyles, however, each community is different and has different resources available that may vary this risk. Oftentimes, larger worksites are associated with increased occupational sitting. Those who work in environments that are classified as business and office jobs are typically more exposed to sitting and sedentary behavior while in the workplace. Additionally, occupations that are full-time, have schedule flexibility, are also included in that demographic, and are more likely to sit often throughout their workday.


Policy implementation

Obstacles surrounding better ergonomic features to sedentary employees include cost, time, effort and for both companies and employees. The evidence above helps establish the importance of ergonomics in a sedentary workplace, yet missing information from this problem is enforcement and policy implementation. As a modernized workplace becomes more and more technology based more jobs are becoming primarily seated, therefore leading to a need to prevent chronic injuries and pain. This is becoming easier with the amount of research around ergonomic tools saving money companies by limiting the number of days missed from work and workers comp cases. The way to ensure that corporations prioritize these health outcomes for their employees is through policy and implementation. Nationwide there are no policies that are currently in place, however a handful of big companies and states have taken on cultural policies to insure the safety of all workers. For example, the state of Nevada risk management department has established a set of ground rules for both agencies responsibilities and employees responsibilities. The agency responsibilities include evaluating workstations, using risk management resources when necessary and keeping OSHA records.

Methods

Until recently, methods used to evaluate human factors and ergonomics ranged from simple questionnaires to more complex and expensive usability labs. Some of the more common human factors methods are listed below: *Ethnographic analysis: Using methods derived from
ethnography Ethnography (from Greek ''ethnos'' "folk, people, nation" and ''grapho'' "I write") is a branch of anthropology and the systematic study of individual cultures. Ethnography explores cultural phenomena from the point of view of the subject o ...
, this process focuses on observing the uses of technology in a practical environment. It is a qualitative and observational method that focuses on "real-world" experience and pressures, and the usage of technology or environments in the workplace. The process is best used early in the design process. *
Focus Groups A focus group is a group interview involving a small number of demographically similar people or participants who have other common traits/experiences. Their reactions to specific researcher/evaluator-posed questions are studied. Focus groups are ...
are another form of qualitative research in which one individual will facilitate discussion and elicit opinions about the technology or process under investigation. This can be on a one-to-one interview basis, or in a group session. Can be used to gain a large quantity of deep qualitative data, though due to the small sample size, can be subject to a higher degree of individual bias.Wickens, C.D.; Lee J.D.; Liu Y.; Gorden Becker S.E. (1997). An Introduction to Human Factors Engineering, 2nd Edition. Prentice Hall. . Can be used at any point in the design process, as it is largely dependent on the exact questions to be pursued, and the structure of the group. Can be extremely costly. *
Iterative design Iterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Based on the results of testing the most recent iteration of a design, changes and refinements are made. T ...
: Also known as prototyping, the iterative design process seeks to involve users at several stages of design, to correct problems as they emerge. As prototypes emerge from the design process, these are subjected to other forms of analysis as outlined in this article, and the results are then taken and incorporated into the new design. Trends among users are analyzed, and products redesigned. This can become a costly process, and needs to be done as soon as possible in the design process before designs become too concrete. *
Meta-analysis A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting me ...
: A supplementary technique used to examine a wide body of already existing data or literature to derive trends or form hypotheses to aid design decisions. As part of a literature survey, a meta-analysis can be performed to discern a collective trend from individual variables. *Subjects-in-tandem: Two subjects are asked to work concurrently on a series of tasks while vocalizing their analytical observations. The technique is also known as "Co-Discovery" as participants tend to feed off of each other's comments to generate a richer set of observations than is often possible with the participants separately. This is observed by the researcher, and can be used to discover usability difficulties. This process is usually recorded. *Surveys and questionnaires: A commonly used technique outside of human factors as well, surveys and questionnaires have an advantage in that they can be administered to a large group of people for relatively low cost, enabling the researcher to gain a large amount of data. The validity of the data obtained is, however, always in question, as the questions must be written and interpreted correctly, and are, by definition, subjective. Those who actually respond are in effect self-selecting as well, widening the gap between the sample and the population further. *
Task analysis Task analysis is the analysis of how a task is accomplished, including a detailed description of both manual and mental activities, task and element durations, task frequency, task allocation, task complexity, environmental conditions, necessary cl ...

, task analysis is a way of systematically describing human interaction with a system or process to understand how to match the demands of the system or process to human capabilities. The complexity of this process is generally proportional to the complexity of the task being analyzed, and so can vary in cost and time involvement. It is a qualitative and observational process. Best used early in the design process. *
Human performance modeling Human performance modeling (HPM) is a method of quantifying human behavior, cognition, and processes. It is a tool used by human factors researchers and practitioners for both the analysis of human function and for the development of systems designe ...

Think aloud protocol A think-aloud (or thinking aloud) protocol is a method used to gather data in usability testing in product design and development, in psychology and a range of social sciences (e.g., reading, writing, translation research, decision making, and pro ...
: Also known as "concurrent verbal protocol", this is the process of asking a user to execute a series of tasks or use technology, while continuously verbalizing their thoughts so that a researcher can gain insights as to the users' analytical process. Can be useful for finding design flaws that do not affect task performance, but may have a negative cognitive effect on the user. Also useful for utilizing experts to better understand procedural knowledge of the task in question. Less expensive than focus groups, but tends to be more specific and subjective. *
User analysis In systems design, user analysis is the means by which scientists, engineers and technical writers determine the characteristics of users which will influence the development of software systems or other technological products. During the process, ...
: This process is based around designing for the attributes of the intended user or operator, establishing the characteristics that define them, creating a
persona A persona (plural personae or personas), depending on the context, is the public image of one's personality, the social role that one adopts, or simply a fictional Character (arts), character. The word derives from Latin, where it originally ref ...
for the user. Best done at the outset of the design process, a user analysis will attempt to predict the most common users, and the characteristics that they would be assumed to have in common. This can be problematic if the design concept does not match the actual user, or if the identified are too vague to make clear design decisions from. This process is, however, usually quite inexpensive, and commonly used. *"Wizard of Oz": This is a comparatively uncommon technique but has seen some use in mobile devices. Based upon the
Wizard of Oz experiment In the field of human–computer interaction, a Wizard of Oz experiment is a research experiment in which subjects interact with a computer system that subjects believe to be autonomous, but which is actually being operated or partially operate ...
, this technique involves an operator who remotely controls the operation of a device to imitate the response of an actual computer program. It has the advantage of producing a highly changeable set of reactions, but can be quite costly and difficult to undertake. *Methods analysis is the process of studying the tasks a worker completes using a step-by-step investigation. Each task in broken down into smaller steps until each motion the worker performs is described. Doing so enables you to see exactly where repetitive or straining tasks occur. *Time studies determine the time required for a worker to complete each task. Time studies are often used to analyze cyclical jobs. They are considered "event based" studies because time measurements are triggered by the occurrence of predetermined events. *
Work sampling Work sampling is the statistical technique used for determining the proportion of time spent by workers in various defined categories of activity (e.g. setting up a machine, assembling two parts, idle…etc.). It is as important as all other statis ...
is a method in which the job is sampled at random intervals to determine the proportion of total time spent on a particular task. It provides insight into how often workers are performing tasks which might cause strain on their bodies. * Predetermined time systems are methods for analyzing the time spent by workers on a particular task. One of the most widely used predetermined time system is called Methods-Time-Measurement. Other common work measurement systems include MODAPTS and MOST. Industry specific applications based on PTS are Seweasy, MODAPTS and GSD as seen in paper: . *

method in which the evaluators can apply user perspective to task scenarios to identify design problems. As applied to macroergonomics, evaluators are able to analyze the usability of work system designs to identify how well a work system is organized and how well the workflow is integrated.Brookhuis, K., Hedge, A., Hendrick, H., Salas, E., and Stanton, N. (2005). Handbook of Human Factors and Ergonomics Models. Florida: CRC Press. * Kansei method: This is a method that transforms consumer's responses to new products into design specifications. As applied to macroergonomics, this method can translate employee's responses to changes to a work system into design specifications. *High Integration of Technology, Organization, and People: This is a manual procedure done step-by-step to apply technological change to the workplace. It allows managers to be more aware of the human and organizational aspects of their technology plans, allowing them to efficiently integrate technology in these contexts. *Top modeler: This model helps manufacturing companies identify the organizational changes needed when new technologies are being considered for their process. *Computer-integrated Manufacturing, Organization, and People System Design: This model allows for evaluating computer-integrated manufacturing, organization, and people system design based on knowledge of the system. *Anthropotechnology: This method considers analysis and design modification of systems for the efficient transfer of technology from one culture to another. *

Weaknesses

Problems related to measures of usability include the fact that measures of learning and retention of how to use an interface are rarely employed and some studies treat measures of how users interact with interfaces as synonymous with quality-in-use, despite an unclear relation. Although field methods can be extremely useful because they are conducted in the users' natural environment, they have some major limitations to consider. The limitations include: # Usually take more time and resources than other methods # Very high effort in planning, recruiting, and executing compared with other methods # Much longer study periods and therefore requires much goodwill among the participants # Studies are longitudinal in nature, therefore, attrition can become a problem.
