95-626: The interface on the Samsung Behold is called TouchWiz which is upgraded from the one that was on the Samsung Omnia . With TouchWiz, the Behold got features like "flashy 3D effects, new gesture controls, better integration of photos and contacts, and more haptic feedback ." Overall, Ginny Mies of PC World concluded that the Samsung Behold "is a well-designed touch-screen phone with an impressive feature set" however many reviewers state that there are

190-403: 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" Prior to World War I , the focus of aviation psychology was on the aviator himself, but

285-426: A decade. Ergonomics Ergonomics , also known as human factors or human factors engineering ( HFE ), is the application of psychological and physiological principles to the engineering and design of products, processes, and systems. Primary goals of human factors engineering are to reduce human error , increase productivity and system availability, and enhance safety , health and comfort with

380-482: A few "flaws" that they notice when using this mobile phone. Contributor Wireless and Mobile News states that the biggest drawback of the Samsung Behold compared to one of its major competitors, the Apple iPhone , is the lack of Wi-Fi on this touch-screen phone. The Samsung Behold's "target [audiences] [are] 21 to 35 year [olds]" who are looking for a mobile phone that could do nearly everything. The browser that comes with

475-745: 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. Obstacles surrounding better ergonomic features to sedentary employees include cost, time, effort and for both companies and employees. The evidence above helps establish

570-678: 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

665-420: A history going back to 1902 and had already become well-established in newsrooms and elsewhere by 1920. In reusing them, economy was certainly a consideration, but psychology and the rule of least surprise mattered as well; teleprinters provided a point of interface with the system that was familiar to many engineers and users. The widespread adoption of video-display terminals (VDTs) in the mid-1970s ushered in

760-408: A job to a batch machine involved first preparing a deck of punched cards that described a program and its dataset. The program cards were not punched on the computer itself but on keypunches , specialized, typewriter-like machines that were notoriously bulky, unforgiving, and prone to mechanical failure. The software interface was similarly unforgiving, with very strict syntaxes designed to be parsed by

855-565: A machine in the way which produces the desired result (i.e. maximum usability ). This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the user. User interfaces are composed of one or more layers, including a human–machine interface ( HMI ) that typically interfaces machines with physical input hardware (such as keyboards, mice, or game pads) and output hardware (such as computer monitors , speakers, and printers ). A device that implements an HMI

1140-400: A predominantly North American term which has been adopted to emphasize the application of the same methods to non-work-related situations. A "human factor" is a physical or cognitive property of an individual or social behavior specific to humans that may influence the functioning of technological systems. The terms "human factors" and "ergonomics" are essentially synonymous. According to

1235-438: A relatively heavy mnemonic load on the user, requiring a serious investment of effort and learning time to master. The earliest command-line systems combined teleprinters with computers, adapting a mature technology that had proven effective for mediating the transfer of information over wires between human beings. Teleprinters had originally been invented as devices for automatic telegraph transmission and reception; they had

1330-573: A result on magnetic tape or generate some data cards to be used in a later computation. The turnaround time for a single job often spanned entire days. If one was very lucky, it might be hours; there was no real-time response. But there were worse fates than the card queue; some computers required an even more tedious and error-prone process of toggling in programs in binary code using console switches. The very earliest machines had to be partly rewired to incorporate program logic into themselves, using devices known as plugboards . Early batch systems gave

1425-416: A safety culture. Organizations with cultures of concealment or lack of empathy have been shown to have poor safety culture. 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

1520-408: A significant number of additional studies have seen no marked improvement in health outcomes. With the emergence of collaborative robots and smart systems in manufacturing environments, the artificial agents can be used to improve physical ergonomics of human co-workers. For example, during human–robot collaboration the robot can use biomechanical models of the human co-worker in order to adjust

1615-550: A single organism and that it was possible to study the behavior of such an organism. It was the climate for a breakthrough." In the initial 20 years after the World War II, most activities were done by the "founding fathers": Alphonse Chapanis , Paul Fitts , and Small. The beginning of the Cold War led to a major expansion of Defense supported research laboratories. Also, many labs established during WWII started expanding. Most of

1710-520: 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

1805-540: A specific focus on the interaction between the human and equipment. The field is a combination of numerous disciplines, such as psychology , sociology , engineering , biomechanics , industrial design , physiology , anthropometry , interaction design , visual design , user experience , and user interface design . Human factors research employs methods and approaches from these and other knowledge disciplines to study human behavior and generate data relevant to previously stated goals. In studying and sharing learning on

1900-962: 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 human–computer interaction design.) Organizational ergonomics is concerned with the optimization of socio-technical systems, including their organizational structures, policies, and processes. Relevant topics include human communication successes or failures in adaptation to other system elements, crew resource management, work design, work systems , design of working times, teamwork, participatory ergonomics , community ergonomics, cooperative work, new work programs, virtual organizations, remote work , and quality management. Safety culture within an organization of engineers and technicians has been linked to engineering safety with cultural dimensions including power distance and ambiguity tolerance. Low power distance has been shown to be more conducive to

1995-562: A variety of backgrounds, though predominantly they are psychologists (from the various subfields of industrial and organizational psychology , engineering psychology , cognitive psychology , perceptual psychology , applied psychology , and experimental psychology ) and physiologists. Designers (industrial, interaction, and graphic), anthropologists, technical communication scholars and computer scientists also contribute. Typically, an ergonomist will have an undergraduate degree in psychology, engineering, design or health sciences , and usually

2090-418: Is a general principle in the design of all kinds of interfaces. It is based on the idea that human beings can only pay full attention to one thing at one time, leading to the conclusion that novelty should be minimized. If an interface is used persistently, the user will unavoidably develop habits for using the interface. The designer's role can thus be characterized as ensuring the user forms good habits. If

2185-751: 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. 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

2280-400: Is better described as a direct neural interface . However, this latter usage is seeing increasing application in the real-life use of (medical) prostheses —the artificial extension that replaces a missing body part (e.g., cochlear implants ). In some circumstances, computers might observe the user and react according to their actions without specific commands. A means of tracking parts of

2375-406: Is called a human interface device (HID). User interfaces that dispense with the physical movement of body parts as an intermediary step between the brain and the machine use no input or output devices except electrodes alone; they are called brain–computer interfaces (BCIs) or brain–machine interfaces (BMIs). Other terms for human–machine interfaces are man–machine interface ( MMI ) and, when

2470-446: Is composed of a tactile UI and a visual UI capable of displaying graphics . When sound is added to a GUI, it becomes a multimedia user interface (MUI). There are three broad categories of CUI: standard , virtual and augmented . Standard CUI use standard human interface devices like keyboards, mice, and computer monitors. When the CUI blocks out the real world to create a virtual reality ,

2565-420: 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

2660-464: Is important to those diagnosed with physiological ailments or disorders such as arthritis (both chronic and temporary) or carpal tunnel syndrome . Pressure that is insignificant or imperceptible to those unaffected by these disorders may be very painful, or render a device unusable, for those who are. Many ergonomically designed products are also used or recommended to treat or prevent such disorders, and to treat pressure-related chronic pain . One of

2755-494: 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

2850-449: Is the number of senses interfaced with. For example, a Smell-O-Vision is a 3-sense (3S) Standard CUI with visual display, sound and smells; when virtual reality interfaces interface with smells and touch it is said to be a 4-sense (4S) virtual reality interface; and when augmented reality interfaces interface with smells and touch it is said to be a 4-sense (4S) augmented reality interface. The user interface or human–machine interface

2945-492: Is the part of the machine that handles the human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples of the physical part of the Human Machine Interface which we can see and touch. In complex systems, the human–machine interface is typically computerized. The term human–computer interface refers to this kind of system. In the context of computing, the term typically extends as well to

3325-429: The industrial design field of human–computer interaction , a user interface ( UI ) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include

3420-416: The "fit" between the user, equipment, and environment or "fitting a job to a person" or "fitting the task to the man". It accounts for the user's capabilities and limitations in seeking to ensure that tasks, functions, information, and the environment suit that user. To assess the fit between a person and the used technology, human factors specialists or ergonomists consider the job (activity) being done and

The Human Factors and Ergonomics Society (HFES) was founded in 1957. The Society's mission is to promote the discovery and exchange of knowledge concerning

4370-504: 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. In 1943 Alphonse Chapanis , a lieutenant in the U.S. Army, showed that this so-called " pilot error " could be greatly reduced when more logical and differentiable controls replaced confusing designs in airplane cockpits.

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

Additional UI layers may interact with one or more human senses, including: tactile UI ( touch ), visual UI ( sight ), auditory UI ( sound ), olfactory UI ( smell ), equilibria UI ( balance ), and gustatory UI ( taste ). Composite user interfaces ( CUIs ) are UIs that interact with two or more senses. The most common CUI is a graphical user interface (GUI), which

6555-507: 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

Another function of the monitor was to do better error checking on submitted jobs, catching errors earlier and more intelligently and generating more useful feedback to the users. Thus, monitors represented the first step towards both operating systems and explicitly designed user interfaces. Command-line interfaces ( CLIs ) evolved from batch monitors connected to the system console. Their interaction model

6745-417: The more common human factors methods are listed below: 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 input side of the user interfaces for batch machines was mainly punched cards or equivalent media like paper tape . The output side added line printers to these media. With the limited exception of the system operator's console , human beings did not interact with batch machines in real time at all. Submitting

7505-511: The period saw a maturation of the discipline. The field has expanded with the development of the computer and computer applications. The Space Age created new human factors issues such as weightlessness and extreme g-forces . Tolerance of the harsh environment of space and its effects on the mind and body were widely studied. The dawn of the Information Age has resulted in the related field of human–computer interaction (HCI). Likewise,

7600-422: The research following the war was military-sponsored. Large sums of money were granted to universities to conduct research. The scope of the research also broadened from small equipments to entire workstations and systems. 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,

7695-402: The science of ergonomics appear to have been laid within the context of the culture of Ancient Greece . A good deal of evidence indicates that Greek civilization in the 5th century BC used ergonomic principles in the design of their tools, jobs, and workplaces. One outstanding example of this can be found in the description Hippocrates gave of how a surgeon's workplace should be designed and how

7790-447: The second phase of command-line systems. These cut latency further, because characters could be thrown on the phosphor dots of a screen more quickly than a printer head or carriage can move. They helped quell conservative resistance to interactive programming by cutting ink and paper consumables out of the cost picture, and were to the first TV generation of the late 1950s and 60s even more iconic and comfortable than teleprinters had been to

7885-569: The simple design of the music player, for users who wish to use the Samsung Behold as a business handy phone, it does not allow for Microsoft Office documents to be opened but it allows PDF files to load, lacking a standard headphone jack. The Samsung Behold features the music video "Somewhere Else" by YouTube celebrity, Jodie Rivera a.k.a. VenetianPrincess . Samsung claimed "to have represented exactly one quarter of all touchscreen phones shipped in 2008", estimating "that it produced about 10 million models of various kinds". Five million of these were

7980-404: The smallest possible compilers and interpreters. Once the cards were punched, one would drop them in a job queue and wait. Eventually, operators would feed the deck to the computer, perhaps mounting magnetic tapes to supply another dataset or helper software. The job would generate a printout, containing final results or an abort notice with an attached error log. Successful runs might also write

8075-557: The software dedicated to control the physical elements used for human–computer interaction . The engineering of human–machine interfaces is enhanced by considering ergonomics ( human factors ). The corresponding disciplines are human factors engineering (HFE) and usability engineering (UE) which is part of systems engineering . Tools used for incorporating human factors in the interface design are developed based on knowledge of computer science , such as computer graphics , operating systems , programming languages . Nowadays, we use

8170-539: 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. To see specific workstation ergonomic policies and responsibilities click here. Until recently, methods used to evaluate human factors and ergonomics ranged from simple questionnaires to more complex and expensive usability labs. Some of

8265-447: The tools he uses should be arranged. The archaeological record also shows that the early Egyptian dynasties made tools and household equipment that illustrated ergonomic principles. 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

8360-588: The understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design to optimize human well-being and overall system performance. Human factors engineering is relevant in the design of such things as safe furniture and easy-to-use interfaces to machines and equipment. Proper ergonomic design is necessary to prevent repetitive strain injuries and other musculoskeletal disorders , which can develop over time and can lead to long-term disability. Human factors and ergonomics are concerned with

8455-455: The war shifted the focus onto the aircraft, in particular, the design of controls and displays, and the effects of altitude and environmental factors on the pilot. The war saw the emergence of aeromedical research and the need for testing and measurement methods. Studies on driver behavior started gaining momentum during this period, as Henry Ford started providing millions of Americans with automobiles. Another major development during this period

8550-590: The war, the Army Air Force published 19 volumes summarizing what had been established from research during the war. In the decades since World War II, human factors has continued to flourish and diversify. Work by Elias Porter and others within the RAND Corporation after WWII extended the conception of human factors. "As the thinking progressed, a new concept developed—that it was possible to view an organization such as an air-defense, man-machine system as

8645-450: 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 , at the 1949 meeting at the UK's Admiralty , which led to the foundation of The Ergonomics Society . He used it to encompass the studies in which he had been engaged during and after World War II. The expression human factors is

8740-502: The working configuration and account for various ergonomic metrics, such as human posture, joint torques, arm manipulability and muscle fatigue . The ergonomic suitability of the shared workspace with respect to these metrics can also be displayed to the human with workspace maps through visual interfaces. 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

8835-496: Was a series of request-response transactions, with requests expressed as textual commands in a specialized vocabulary. Latency was far lower than for batch systems, dropping from days or hours to seconds. Accordingly, command-line systems allowed the user to change their mind about later stages of the transaction in response to real-time or near-real-time feedback on earlier results. Software could be exploratory and interactive in ways not possible before. But these interfaces still placed

8930-445: Was founded by the coal industry in 1969. From the outset the IOM employed an ergonomics staff to apply ergonomics principles to the design of mining machinery and environments. To this day, the IOM continues ergonomics activities, especially in the fields of musculoskeletal disorders ; heat stress and the ergonomics of personal protective equipment (PPE). Like many in occupational ergonomics,

9025-451: Was the performance of aeromedical research. By the end of World War I, two aeronautical labs were established, one at Brooks Air Force Base , Texas and the other at Wright-Patterson Air Force Base outside of Dayton, Ohio . Many tests were conducted to determine which characteristic differentiated the successful pilots from the unsuccessful ones. During the early 1930s, Edwin Link developed
