Because of this, the U.S. Treasury Department sanctioned Blender.io, which marked the first time it has taken action against a mixer, to try to crack down on North Korean hackers. The privacy of cryptocurrency has been debated. Although many customers like

500-408: A software application , website, book , tool , machine , process, vehicle , or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers , technical writers , marketing personnel, and others. It is widely used in consumer electronics , communication , and knowledge transfer objects (such as

Tree testing is a way to evaluate the effectiveness of a website's top-down organization. Participants are given "find it" tasks, then asked to drill down through successive text lists of topics and subtopics to find

750-478: A better design solution only because it would require a novel approach and to stick with boring designs. However, applying familiar features into a new interface has been shown not to result in boring design if designers use creative approaches rather than simple copying. The throwaway remark that "the only intuitive interface is the nipple; everything else is learned." is still occasionally mentioned. Any breastfeeding mother or lactation consultant will tell you this

875-419: A cookbook, a document or online help ) and mechanical objects such as a door handle or a hammer. Usability includes methods of measuring usability, such as needs analysis and the study of the principles behind an object's perceived efficiency or elegance. In human-computer interaction and computer science , usability studies the elegance and clarity with which the interaction with a computer program or

1000-478: A critical role in science , engineering , and everyday life . Technological advancements have led to significant changes in society. The earliest known technology is the stone tool , used during prehistory , followed by the control of fire —which in turn contributed to the growth of the human brain and the development of language during the Ice Age , according to the cooking hypothesis . The invention of

1125-416: A goal. A method is a sequence of operators that accomplish a goal. Selection rules specify which method satisfies a given goal, based on context. Sometimes it is useful to break a task down and analyze each individual aspect separately. This helps the tester locate specific areas for improvement. To do this, it is necessary to understand how the human brain processes information. A model of the human processor

1250-425: A group of 6 to 10 users are gathered to discuss what they desire in a product. An experienced focus group facilitator is hired to guide the discussion to areas of interest for the developers. Focus groups are typically videotaped to help get verbatim quotes, and clips are often used to summarize opinions. The data gathered is not usually quantitative, but can help get an idea of a target group's opinion. Surveys have

1375-448: A low tolerance for difficult designs or slow sites. People don't want to wait. And they don't want to learn how to use a home page. There's no such thing as a training class or a manual for a Web site. People have to be able to grasp the functioning of the site immediately after scanning the home page—for a few seconds at most." Otherwise, most casual users simply leave the site and browse or shop elsewhere. Usability can also include

1500-457: A method used in early stages of development to validate and refine the usability of a system. It can be used to quickly and cheaply evaluate user-interface designs without the need for an expensive working model. This can help remove hesitation to change the design, since it is implemented before any real programming begins. One such method of rapid prototyping is paper prototyping . These usability evaluation methods involve testing of subjects for

1625-606: A method, consider cost, time constraints, and appropriateness. For a brief overview of methods, see Comparison of usability evaluation methods or continue reading below. Usability methods can be further classified into the subcategories below. Cognitive modeling involves creating a computational model to estimate how long it takes people to perform a given task. Models are based on psychological principles and experimental studies to determine times for cognitive processing and motor movements. Cognitive models can be used to improve user interfaces or predict problem errors and pitfalls during

1750-456: A more refined prototype, designers often test effectiveness, efficiency, and subjective satisfaction, by asking the user to complete various tasks. These categories are measured by the percent that complete the task, how long it takes to complete the tasks, ratios of success to failure to complete the task, time spent on errors, the number of errors, rating scale of satisfactions, number of times user seems frustrated, etc. Additional observations of

1875-400: A parts library and a method used for identifying the connection between the parts.  This approach can be used by almost anyone and it is a great asset for designers with repetitive tasks. This approach is a combination of the tool kit approach and the part kit approach. Both the dialogue designers and the programmers are able to interact with this prototyping tool. Rapid prototyping is

2000-407: A product with good usability. Usability is a non-functional requirement . As with other non-functional requirements, usability cannot be directly measured but must be quantified by means of indirect measures or attributes such as, for example, the number of reported problems with ease-of-use of a system. The term intuitive is often listed as a desirable trait in usable interfaces, sometimes used as

2125-458: A proposed system. One way to stress the importance of these issues in the designers' minds is to use personas, which are made-up representative users. See below for further discussion of personas. Another more expensive but more insightful method is to have a panel of potential users work closely with the design team from the early stages. Test the system early on, and test the system on real users using behavioral measurements. This includes testing

2250-634: A range of researchers across the world, and intuitive interaction is accepted in the research community as being use of an interface based on past experience with similar interfaces or something else, often not fully conscious, and sometimes involving a feeling of "magic" since the course of the knowledge itself may not be consciously available to the user . Researchers have also investigated intuitive interaction for older people, people living with dementia, and children. Some have argued that aiming for "intuitive" interfaces (based on reusing existing skills with interaction systems) could lead designers to discard

2375-486: A result, philosophical and political debates about the role and use of technology, the ethics of technology , and ways to mitigate its downsides are ongoing. Technology is a term dating back to the early 17th century that meant 'systematic treatment' (from Greek Τεχνολογία , from the Greek : τέχνη , romanized :  tékhnē , lit.   'craft, art' and -λογία , 'study, knowledge'). It

The word technology can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines , and intangible ones such as software . Technology plays

2625-410: A rise in extremism, while others see it as an opportunity to usher in a post-scarcity economy . Some segments of the 1960s hippie counterculture grew to dislike urban living and developed a preference for locally autonomous , sustainable , and decentralized technology, termed appropriate technology . This later influenced hacker culture and technopaganism . Technological utopianism refers to

2750-411: A rise in social media's cultural prominence, with potential repercussions on democracy, and economic and social life. Early on, the internet was seen as a "liberation technology" that would democratize knowledge, improve access to education, and promote democracy. Modern research has turned to investigate the internet's downsides, including disinformation, polarization, hate speech, and propaganda. Since

2875-517: A role. The invention of writing led to the spread of cultural knowledge and became the basis for history, libraries , schools, and scientific research. Continuing improvements led to the furnace and bellows and provided, for the first time, the ability to smelt and forge gold, copper, silver, and lead – native metals found in relatively pure form in nature. The advantages of copper tools over stone, bone and wooden tools were quickly apparent to early humans, and native copper

3000-521: A source of ideas. Futures research methodologies include survey research , modeling, statistical analysis , and computer simulations . Existential risk researchers analyze risks that could lead to human extinction or civilizational collapse, and look for ways to build resilience against them. Relevant research centers include the Cambridge Center for the Study of Existential Risk , and

3125-408: A suitable answer. Tree testing evaluates the findability and labeling of topics in a site, separate from its navigation controls or visual design . Ethnographic analysis is derived from anthropology. Field observations are taken at a site of a possible user, which track the artifacts of work such as Post-It notes, items on desktop, shortcuts, and items in trash bins. These observations also gather

3250-510: A synonym for learnable . In the past, Jef Raskin discouraged using this term in user interface design, claiming that easy to use interfaces are often easy because of the user's exposure to previous similar systems, thus the term 'familiar' should be preferred. As an example: Two vertical lines "||" on media player buttons do not intuitively mean "pause"—they do so by convention. This association between intuitive use and familiarity has since been empirically demonstrated in multiple studies by

3375-409: A task scenario. As more people inspect the scenario for problems, the higher the probability to find problems. In addition, the more interaction in the team, the faster the usability issues are resolved. In consistency inspection, expert designers review products or projects to ensure consistency across multiple products to look if it does things in the same way as their own designs. Activity analysis

3500-405: A third analysis is often used: understanding users' environments (physical, social, cultural, and technological environments). A focus group is a focused discussion where a moderator leads a group of participants through a set of questions on a particular topic. Although typically used as a marketing tool, focus groups are sometimes used to evaluate usability. Used in the product definition stage,

3625-504: A vehicle to easily solicit feedback from users in remote areas. There are two types, quantitative or qualitative. Quantitative use large sample sized and task based surveys. These types of studies are useful for validating suspected usability issues. Qualitative studies are best used as exploratory research, in small sample sizes but frequent, even daily iterations. Qualitative usually allows for observing respondent's screens and verbal think aloud commentary (Screen Recording Video, SRV), and for

3750-408: A web site ( web usability ) is designed. Usability considers user satisfaction and utility as quality components, and aims to improve user experience through iterative design . The primary notion of usability is that an object designed with a generalized users' psychology and physiology in mind is, for example: Complex computer systems find their way into everyday life, and at the same time

3875-457: A website's usability review. Participants in a card sorting session are asked to organize the content from a Web site in a way that makes sense to them. Participants review items from a Web site and then group these items into categories. Card sorting helps to learn how users think about the content and how they would organize the information on the Web site. Card sorting helps to build the structure for

4000-540: Is a process for generating and reflecting on tangible ideas by allowing failure to occur early. prototyping helps people to see what could be of communicating a shared vision, and of giving shape to the future. The types of usability prototypes may vary from using paper models, index cards, hand drawn models, or storyboards. Prototypes are able to be modified quickly, often are faster and easier to create with less time invested by designers and are more apt to change design; although sometimes are not an adequate representation of

Emerging technologies are novel technologies whose development or practical applications are still largely unrealized. They include nanotechnology , biotechnology , robotics , 3D printing , blockchains , and artificial intelligence . In 2005, futurist Ray Kurzweil claimed

4375-499: Is an interdisciplinary subfield of ethics that analyzes technology's ethical implications and explores ways to mitigate the potential negative impacts of new technologies. There is a broad range of ethical issues revolving around technology, from specific areas of focus affecting professionals working with technology to broader social, ethical, and legal issues concerning the role of technology in society and everyday life. Prominent debates have surrounded genetically modified organisms ,

With the growing reliance of technology, there have been security and privacy concerns along with it. Billions of people use different online payment methods, such as WeChat Pay , PayPal , Alipay , and much more to help transfer money. Although security measures are placed, some criminals are able to bypass them. In March 2022, North Korea used Blender.io ,

4625-433: Is essentially a less comprehensive version of GOMS that makes simplifying assumptions in order to reduce calculation time and complexity. These usability evaluation methods involve observation of users by an experimenter, or the testing and evaluation of a program by an expert reviewer. They provide more quantitative data as tasks can be timed and recorded. Card sorting is a way to involve users in grouping information for

4750-419: Is inaccurate and the nipple does in fact require learning on both sides. In 1992, Bruce Tognazzini even denied the existence of "intuitive" interfaces, since such interfaces must be able to intuit, i.e., "perceive the patterns of the user's behavior and draw inferences." Instead, he advocated the term "intuitable," i.e., "that users could intuit the workings of an application by seeing it and using it". However,

4875-503: Is needed, or "What do we want to know?" The following usability evaluation methods involve collecting qualitative data from users. Although the data collected is subjective, it provides valuable information on what the user wants. Task analysis means learning about users' goals and users' ways of working. Task analysis can also mean figuring out what more specific tasks users must do to meet those goals and what steps they must take to accomplish those tasks. Along with user and task analysis,

5000-621: Is no set method to determine the correct solution. Rather, there are empirical methods that can be used during system development or after the system is delivered, usually a more inopportune time. Ultimately, iterative design works towards meeting goals such as making the system user friendly, easy to use, easy to operate, simple, etc. There are a variety of usability evaluation methods. Certain methods use data from users, while others rely on usability experts. There are usability evaluation methods for all stages of design and development, from product definition to final design modifications. When choosing

5125-431: Is often very difficult for designers to conduct usability tests with the exact system being designed. Cost constraints, size, and design constraints usually lead the designer to creating a prototype of the system. Instead of creating the complete final system, the designer may test different sections of the system, thus making several small models of each component of the system. Prototyping is an attitude and an output, as it

6500-611: The World Economic Forum 's "The Future of Jobs Report 2020", AI is predicted to replace 85 million jobs worldwide, and create 97 million new jobs by 2025. From 1990 to 2007, a study in the U.S. by MIT economist Daron Acemoglu showed that an addition of one robot for every 1,000 workers decreased the employment-to-population ratio by 0.2%, or about 3.3 workers, and lowered wages by 0.42%. Concerns about technology replacing human labor however are long-lasting. As US president Lyndon Johnson said in 1964, "Technology

Complex manufacturing and construction techniques and organizations are needed to make and maintain more modern technologies, and entire industries have arisen to develop succeeding generations of increasingly more complex tools. Modern technology increasingly relies on training and education – their designers, builders, maintainers, and users often require sophisticated general and specific training. Moreover, these technologies have become so complex that entire fields have developed to support them, including engineering, medicine, and computer science ; and other fields have become more complex, such as construction, transportation, and architecture.

Philosophy of technology is a branch of philosophy that studies the "practice of designing and creating artifacts", and the "nature of the things so created." It emerged as a discipline over the past two centuries, and has grown "considerably" since

7000-595: The wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press , telephone, and the Internet , have lowered barriers to communication and ushered in the knowledge economy . While technology contributes to economic development and improves human prosperity , it can also have negative impacts like pollution and resource depletion , and can cause social harms like technological unemployment resulting from automation . As

Since the invention of the wheel, technologies have helped increase humans' economic output. Past automation has both substituted and complemented labor; machines replaced humans at some lower-paying jobs (for example in agriculture), but this

7250-429: The 1970s. The humanities philosophy of technology is concerned with the "meaning of technology for, and its impact on, society and culture". Initially, technology was seen as an extension of the human organism that replicated or amplified bodily and mental faculties. Marx framed it as a tool used by capitalists to oppress the proletariat, but believed that technology would be a fundamentally liberating force once it

In the 20th century, as a result of scientific progress and the Second Industrial Revolution , technology stopped being considered a distinct academic discipline and took on the meaning: the systemic use of knowledge to practical ends. Tools were initially developed by hominids through observation and trial and error . Around 2 Mya (million years ago), they learned to make

8250-411: The advantages of being inexpensive, require no testing equipment, and results reflect the users' opinions. When written carefully and given to actual users who have experience with the product and knowledge of design, surveys provide useful feedback on the strong and weak areas of the usability of a design. This is a very common method and often does not appear to be a survey, but just a warranty card. It

Measures of technological innovation correlates with a rise in greenhouse gas emissions. Pollution, the presence of contaminants in an environment that causes adverse effects, could have been present as early as the Inca Empire . They used a lead sulfide flux in

8875-490: The belief that technological development is a moral good , which can and should bring about a utopia , that is, a society in which laws, governments, and social conditions serve the needs of all its citizens. Examples of techno-utopian goals include post-scarcity economics , life extension , mind uploading , cryonics , and the creation of artificial superintelligence . Major techno-utopian movements include transhumanism and singularitarianism . The transhumanism movement

9000-412: The best ideas from each design are integrated into the final concept. This process can be repeated several times until the team is satisfied with the final concept. GOMS stands for goals, operators, methods, and selection rules . It is a family of techniques that analyzes the user complexity of interactive systems. Goals are what the user must accomplish. An operator is an action performed in pursuit of

In software engineering , usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use. The object of use can be

9250-557: The city-state of Ur dates to around 3,429 BCE, and even older fragments of wheel-thrown pottery have been found in the same area. Fast (rotary) potters' wheels enabled early mass production of pottery, but it was the use of the wheel as a transformer of energy (through water wheels , windmills, and even treadmills) that revolutionized the application of nonhuman power sources. The first two-wheeled carts were derived from travois and were first used in Mesopotamia and Iran in around 3,000 BCE. The oldest known constructed roadways are

9375-535: The communication of knowledge. Technology became increasingly influenced by science, beginning a cycle of mutual advancement. Starting in the United Kingdom in the 18th century, the discovery of steam power set off the Industrial Revolution , which saw wide-ranging technological discoveries, particularly in the areas of agriculture , manufacturing, mining, metallurgy , and transport, and

9500-476: The concept of prototypicality, which is how much a particular thing conforms to the expected shared norm, for instance, in website design, users prefer sites that conform to recognised design norms. ISO defines usability as "The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use." The word "usability" also refers to methods for improving ease-of-use during

9625-400: The context of mainstream consumer products, an automobile lacking a reverse gear could be considered unusable according to the former view, and lacking in utility according to the latter view. When evaluating user interfaces for usability, the definition can be as simple as "the perception of a target user of the effectiveness (fit for purpose) and efficiency (work or time required to use) of

9750-440: The design process. A few examples of cognitive models include: With parallel design, several people create an initial design from the same set of requirements. Each person works independently, and when finished, shares concepts with the group. The design team considers each solution, and each designer uses the best ideas to further improve their own solution. This process helps generate many different, diverse ideas, and ensures that

9875-537: The design process. Usability consultant Jakob Nielsen and computer science professor Ben Shneiderman have written (separately) about a framework of system acceptability, where usability is a part of "usefulness" and is composed of: Usability is often associated with the functionalities of the product (cf. ISO definition, below), in addition to being solely a characteristic of the user interface (cf. framework of system acceptability, also below, which separates usefulness into usability and utility ). For example, in

10000-399: The design team. The term user friendly is often used as a synonym for usable , though it may also refer to accessibility . Usability describes the quality of user experience across websites, software, products, and environments. There is no consensus about the relation of the terms ergonomics (or human factors ) and usability. Some think of usability as the software specialization of

10125-444: The design, construction, use, and treatment of robots, as well as machine ethics , which is concerned with ensuring the ethical behavior of artificially intelligent agents . Within the field of AI ethics, significant yet-unsolved research problems include AI alignment (ensuring that AI behaviors are aligned with their creators' intended goals and interests) and the reduction of algorithmic bias . Some researchers have warned against

10250-468: The extent necessary to allow managers to understand their relevance and importance in the design process as a whole. The guidance in ISO/TR 16982:2002 can be tailored for specific design situations by using the lists of issues characterizing the context of use of the product to be delivered. Selection of appropriate usability methods should also take account of the relevant life-cycle process. ISO/TR 16982:2002

10375-553: The first stone tools by hammering flakes off a pebble, forming a sharp hand axe . This practice was refined 75 kya (thousand years ago) into pressure flaking , enabling much finer work. The discovery of fire was described by Charles Darwin as "possibly the greatest ever made by man". Archaeological, dietary, and social evidence point to "continuous [human] fire-use" at least 1.5 Mya. Fire, fueled with wood and charcoal , allowed early humans to cook their food to increase its digestibility, improving its nutrient value and broadening

10500-517: The fur and hides of hunted animals, helped humanity expand into colder regions; humans began to migrate out of Africa around 200 kya, initially moving to Eurasia . The Neolithic Revolution (or First Agricultural Revolution ) brought about an acceleration of technological innovation, and a consequent increase in social complexity. The invention of the polished stone axe was a major advance that allowed large-scale forest clearance and farming. This use of polished stone axes increased greatly in

10625-441: The hypothetical risk of an AI takeover , and have advocated for the use of AI capability control in addition to AI alignment methods. Other fields of ethics have had to contend with technology-related issues, including military ethics , media ethics , and educational ethics . Futures studies is the systematic and interdisciplinary study of social and technological progress. It aims to quantitatively and qualitatively explore

10750-488: The introduction of skyscrapers accompanied by rapid urbanization. Communication improved with the invention of the telegraph , the telephone, the radio, and television. The 20th century brought a host of innovations. In physics, the discovery of nuclear fission in the Atomic Age led to both nuclear weapons and nuclear power . Analog computers were invented and asserted dominance in processing complex data. While

10875-508: The invention of vacuum tubes allowed for digital computing with computers like the ENIAC , their sheer size precluded widespread use until innovations in quantum physics allowed for the invention of the transistor in 1947, which significantly compacted computers and led the digital transition. Information technology, particularly optical fiber and optical amplifiers , allowed for simple and fast long-distance communication, which ushered in

11000-404: The issue more thoroughly; others fear that directed evolution could lead to eugenics or extreme social inequality. Nanotechnology will grant us the ability to manipulate matter "at the molecular and atomic scale", which could allow us to reshape ourselves and our environment in fundamental ways. Nanobots could be used within the human body to destroy cancer cells or form new body parts, blurring

11125-410: The larger topic of ergonomics. Others view these topics as tangential, with ergonomics focusing on physiological matters (e.g., turning a door handle) and usability focusing on psychological matters (e.g., recognizing that a door can be opened by turning its handle). Usability is also important in website development ( web usability ). According to Jakob Nielsen , "Studies of user behavior on the Web find

11250-690: The line between biology and technology. Autonomous robots have undergone rapid progress, and are expected to replace humans at many dangerous tasks, including search and rescue , bomb disposal , firefighting , and war. Estimates on the advent of artificial general intelligence vary, but half of machine learning experts surveyed in 2018 believe that AI will "accomplish every task better and more cheaply" than humans by 2063, and automate all human jobs by 2140. This expected technological unemployment has led to calls for increased emphasis on computer science education and debates about universal basic income . Political science experts predict that this could lead to

11375-518: The market is saturated with competing brands . This has made usability more popular and widely recognized in recent years, as companies see the benefits of researching and developing their products with user-oriented methods instead of technology -oriented methods. By understanding and researching the interaction between product and user, the usability expert can also provide insight that is unattainable by traditional company-oriented market research . For example, after observing and interviewing users,

11500-967: The more generic Ergonomics of Human System Interaction . As part of this change, ISO is renumbering some parts of the standard so that it can cover more topics, e.g. tactile and haptic interaction. The first part to be renumbered was part 10 in 2006, now part 110. IEC 62366 -1:2015 + COR1:2016 & IEC/TR 62366-2 provide guidance on usability engineering specific to a medical device . Any system or device designed for use by people should be easy to use, easy to learn, easy to remember (the instructions), and helpful to users. John Gould and Clayton Lewis recommend that designers striving for usability follow these three design principles The design team should be user-driven and it should be in direct contact with potential users. Several evaluation methods , including personas , cognitive modeling , inspection, inquiry, prototyping , and testing methods may contribute to understanding potential users and their perceptions of how well

11625-480: The most quantitative data. Usually recorded on video, they provide task completion time and allow for observation of attitude. Regardless to how carefully a system is designed, all theories must be tested using usability tests. Usability tests involve typical users using the system (or product) in a realistic environment [see simulation ]. Observation of the user's behavior, emotions, and difficulties while performing different tasks, often identify areas of improvement for

11750-594: The nature of rules of thumb than specific usability guidelines. Thus, by determining which guidelines are violated, the usability of a device can be determined. Usability inspection is a review of a system based on a set of guidelines. The review is conducted by a group of experts who are deeply familiar with the concepts of usability in design. The experts focus on a list of areas in design that have been shown to be troublesome for users. Pluralistic Inspections are meetings where users, developers, and human factors people meet together to discuss and evaluate step by step of

11875-417: The next technological revolution would rest upon advances in genetics , nanotechnology , and robotics , with robotics being the most impactful of the three technologies. Genetic engineering will allow far greater control over human biological nature through a process called directed evolution . Some thinkers believe that this may shatter our sense of self, and have urged for renewed public debate exploring

12000-419: The notion of a vulnerable world , "one in which there is some level of technological development at which civilization almost certainly gets devastated by default", citing the risks of a pandemic caused by bioterrorists , or an arms race triggered by the development of novel armaments and the loss of mutual assured destruction . He invites policymakers to question the assumptions that technological progress

12125-443: The number of foods that could be eaten. The cooking hypothesis proposes that the ability to cook promoted an increase in hominid brain size , though some researchers find the evidence inconclusive. Archaeological evidence of hearths was dated to 790 kya; researchers believe this is likely to have intensified human socialization and may have contributed to the emergence of language . Other technological advances made during

12250-507: The oldest-known wooden wheel in the world as of 2024 was found in the Ljubljana Marsh of Slovenia ; Austrian experts have established that the wheel is between 5,100 and 5,350 years old. The invention of the wheel revolutionized trade and war. It did not take long to discover that wheeled wagons could be used to carry heavy loads. The ancient Sumerians used a potter's wheel and may have invented it. A stone pottery wheel found in

12375-553: The privacy of cryptocurrency, many also argue that it needs more transparency and stability. Technology can have both positive and negative effects on the environment. Environmental technology , describes an array of technologies which seek to reverse, mitigate or halt environmental damage to the environment. This can include measures to halt pollution through environmental regulations, capture and storage of pollution, or using pollutant byproducts in other industries. Other examples of environmental technology include deforestation and

12500-520: The product or process works. Usability considerations, such as who the users are and their experience with similar systems must be examined. As part of understanding users, this knowledge must "...be played against the tasks that the users will be expected to perform." This includes the analysis of what tasks the users will perform, which are most important, and what decisions the users will make while using your system. Designers must understand how cognitive and emotional characteristics of users will relate to

12625-417: The progression from early Neolithic villages to the first cities, such as Uruk , and the first civilizations, such as Sumer , is not specifically known; however, the emergence of increasingly hierarchical social structures and specialized labor, of trade and war among adjacent cultures, and the need for collective action to overcome environmental challenges such as irrigation , are all thought to have played

12750-418: The quality and functionality of a design. In iterative design, interaction with the designed system is used as a form of research for informing and evolving a project, as successive versions, or iterations of a design are implemented. The key requirements for Iterative Design are: identification of required changes, an ability to make changes, and a willingness to make changes. When a problem is encountered, there

12875-468: The quantification of user testing studies by providing the ability to generate large sample sizes, or a deep qualitative analysis without the need for dedicated facilities. Additionally, this style of user testing also provides an opportunity to segment feedback by demographic, attitudinal and behavioral type. The tests are carried out in the user's own environment (rather than labs) helping further simulate real-life scenario testing. This approach also provides

13000-409: The range of plausible futures and to incorporate human values in the development of new technologies. More generally, futures researchers are interested in improving "the freedom and welfare of humankind". It relies on a thorough quantitative and qualitative analysis of past and present technological trends, and attempts to rigorously extrapolate them into the future. Science fiction is often used as

13125-414: The results. Often it is quite difficult to distinguish the source of the design errors, and what the user did wrong. However, effective usability tests will not generate a solution to the problems, but provide modified design guidelines for continued testing. Remote usability testing (also known as unmoderated or asynchronous usability testing) involves the use of a specially modified online survey, allowing

13250-401: The reversing of deforestation. Emerging technologies in the fields of climate engineering may be able to halt or reverse global warming and its environmental impacts, although this remains highly controversial. As technology has advanced, so too has the negative environmental impact, with increased release of greenhouse gases , including methane , nitrous oxide and carbon dioxide , into

13375-405: The sequence of work and interruptions that determine the user's typical day. Heuristic evaluation is a usability engineering method for finding and assessing usability problems in a user interface design as part of an iterative design process. It involves having a small set of evaluators examining the interface and using recognized usability principles (the "heuristics"). It is the most popular of

13500-537: The stone-paved streets of the city-state of Ur, dating to c.  4,000 BCE , and timber roads leading through the swamps of Glastonbury , England, dating to around the same period. The first long-distance road, which came into use around 3,500 BCE, spanned 2,400 km from the Persian Gulf to the Mediterranean Sea , but was not paved and was only partially maintained. In around 2,000 BCE,

13625-444: The system for both learnability and usability. (See Evaluation Methods ). It is important in this stage to use quantitative usability specifications such as time and errors to complete tasks and number of users to test, as well as examine performance and attitudes of the users testing the system. Finally, "reviewing or demonstrating" a system before the user tests it can result in misleading results. The emphasis of empirical measurement

13750-447: The system. While conducting usability tests, designers must use usability metrics to identify what it is they are going to measure, or the usability metrics. These metrics are often variable, and change in conjunction with the scope and goals of the project. The number of subjects being tested can also affect usability metrics, as it is often easier to focus on specific demographics. Qualitative design phases, such as general usability (can

13875-481: The task be accomplished?), and user satisfaction are also typically done with smaller groups of subjects. Using inexpensive prototypes on small user groups provides more detailed information, because of the more interactive atmosphere, and the designer's ability to focus more on the individual user. As the designs become more complex, the testing must become more formalized. Testing equipment will become more sophisticated and testing metrics become more quantitative. With

14000-477: The term intuitive interaction has become well accepted in the research community over the past 20 or so years and, although not perfect, it should probably be accepted and used. ISO/TR 16982:2002 (" Ergonomics of human-system interaction—Usability methods supporting human-centered design") is an International Standards Organization (ISO) standard that provides information on human-centered usability methods that can be used for design and evaluation. It details

14125-476: The time, Technologie (German and French) referred either to the academic discipline studying the "methods of arts and crafts", or to the political discipline "intended to legislate on the functions of the arts and crafts." The distinction between Technik and Technologie is absent in English, and so both were translated as technology . The term was previously uncommon in English and mostly referred to

14250-435: The usability expert may identify needed functionality or design flaws that were not anticipated. A method called contextual inquiry does this in the naturally occurring context of the users own environment. In the user-centered design paradigm , the product is designed with its intended users in mind at all times. In the user-driven or participatory design paradigm, some of the users become actual or de facto members of

14375-542: The usability inspection methods, as it is quick, cheap, and easy. Heuristic evaluation was developed to aid in the design of computer user-interface design. It relies on expert reviewers to discover usability problems and then categorize and rate them by a set of principles (heuristics.) It is widely used based on its speed and cost-effectiveness. Jakob Nielsen's list of ten heuristics is the most commonly used in industry. These are ten general principles for user interface design. They are called "heuristics" because they are more in

14500-527: The use of robotic soldiers, algorithmic bias , and the issue of aligning AI behavior with human values. Technology ethics encompasses several key fields. Bioethics looks at ethical issues surrounding biotechnologies and modern medicine, including cloning, human genetic engineering, and stem cell research. Computer ethics focuses on issues related to computing. Cyberethics explores internet-related issues like intellectual property rights , privacy , and censorship . Nanoethics examines issues surrounding

14625-408: The users give designers insight on navigation difficulties, controls, conceptual models, etc. The ultimate goal of analyzing these metrics is to find/create a prototype design that users like and use to successfully perform given tasks. After conducting usability tests, it is important for a designer to record what was observed, in addition to why such behavior occurred and modify the model according to

14750-506: The value judgments that shape technology. Cultural critic Neil Postman distinguished tool-using societies from technological societies and from what he called "technopolies", societies that are dominated by an ideology of technological and scientific progress to the detriment of other cultural practices, values, and world views. Herbert Marcuse and John Zerzan suggest that technological society will inevitably deprive us of our freedom and psychological health. The ethics of technology

14875-481: The whole system, are often not durable and testing results may not be parallel to those of the actual system. This tool kit is a wide library of methods that used the traditional programming language and it is primarily developed for computer programmers. The code created for testing in the tool kit approach can be used in the final product. However, to get the highest benefit from the tool, the user must be an expert programmer. The two elements of this approach include

15000-527: The widespread application of the factory system . This was followed a century later by the Second Industrial Revolution which led to rapid scientific discovery, standardization, and mass production. New technologies were developed, including sewage systems , electricity, light bulbs , electric motors , railroads, automobiles , and airplanes. These technological advances led to significant developments in medicine, chemistry , physics , and engineering. They were accompanied by consequential social change, with

15125-529: Was "freed from societal deformations". Second-wave philosophers like Ortega later shifted their focus from economics and politics to "daily life and living in a techno-material culture", arguing that technology could oppress "even the members of the bourgeoisie who were its ostensible masters and possessors." Third-stage philosophers like Don Ihde and Albert Borgmann represent a turn toward de-generalization and empiricism, and considered how humans can learn to live with technology. Early scholarship on technology

15250-574: Was built in 312 BCE. The eleventh and final ancient Roman aqueduct was built in 226 CE. Put together, the Roman aqueducts extended over 450 km, but less than 70 km of this was above ground and supported by arches. Innovations continued through the Middle Ages with the introduction of silk production (in Asia and later Europe), the horse collar , and horseshoes . Simple machines (such as

15375-513: Was compensated by the creation of new, higher-paying jobs. Studies have found that computers did not create significant net technological unemployment . Due to artificial intelligence being far more capable than computers, and still being in its infancy, it is not known whether it will follow the same trend; the question has been debated at length among economists and policymakers. A 2017 survey found no clear consensus among economists on whether AI would increase long-term unemployment. According to

15500-536: Was probably used from near the beginning of Neolithic times (about 10 kya). Native copper does not naturally occur in large amounts, but copper ores are quite common and some of them produce metal easily when burned in wood or charcoal fires. Eventually, the working of metals led to the discovery of alloys such as bronze and brass (about 4,000 BCE). The first use of iron alloys such as steel dates to around 1,800 BCE. After harnessing fire, humans discovered other forms of energy. The earliest known use of wind power

15625-649: Was split between two arguments: technological determinism , and social construction . Technological determinism is the idea that technologies cause unavoidable social changes. It usually encompasses a related argument, technological autonomy, which asserts that technological progress follows a natural progression and cannot be prevented. Social constructivists argue that technologies follow no natural progression, and are shaped by cultural values, laws, politics, and economic incentives. Modern scholarship has shifted towards an analysis of sociotechnical systems , "assemblages of things, people, practices, and meanings", looking at
