It operates on a rail line known as the Cape Main Line which is owned by Massachusetts Department of Transportation . The line was previously owned and operated by the Cape Cod Railroad , the Old Colony Railroad , and later the New Haven Railroad , each of which operated passenger trains on
222-583: A "code of practice" for making train and stations accessible: "Accessible Train and Station Design for Disabled People: A Code of Practice". This code of practice was first published in 2002 with the objective of compliance to Section 71B of the Railways Act 1993, and revised after a public consultation period in 2008. Some transport companies have since improved the accessibility of their services, such as incorporating low-floor buses into their stock as standard. In August 2021, South Western Railway announced

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
444-478: 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

However, the accessibility of a low-floor vehicle can also be utilised from slightly raising portions of kerb at bus stops , or through use of level boarding bus rapid transit stations or tram stops. The combination of access from a kerb was the technological development of the 1990s, as step-free interior layouts for buses had existed in some cases for decades, with entrance steps being introduced as chassis designs and overall height regulations changed. Low-floor buses may also be designed with special height adjustment controls that permit

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

India, like much of the world, has large sections of the economy that are without strong regulation or social protections, such as
1221-457: 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
SECTION 10
#17328552846001332-606: 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
1443-456: 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
1554-400: 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
1665-407: 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
1776-458: 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
1887-634: 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
1998-440: A range of tasks, and may be suitable for different kinds of disability. The following impairments are some of the disabilities that affect communications and technology access, as well as many other life activities: Each kind of disability requires a different kind of accommodation, and this may require analysis by a medical specialist, an educational specialist or a job analysis when the impairment requires accommodation. One of
2109-537: 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 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
2220-411: A single general solution that can accommodate people with disabilities as well as the rest of the population. By contrast, accessible design is focused on ensuring that there are no barriers to accessibility for all people, including those with disabilities. The disability rights movement advocates equal access to social, political, and economic life which includes not only physical access but access to
2331-541: A standard color code that enables colorblind individuals to understand the correct signal. Adaptive technology is the modification, or adaptation, of existing devices, methods, or the creation of new uses for existing devices, to enable a person to complete a task. Examples include the use of remote controls, and the autocomplete (word completion) feature in computer word processing programs, which both help individuals with mobility impairments to complete tasks. Adaptations to wheelchair tires are another example; widening

At rapid transit systems, vehicles generally have floors in the same height as the platforms but the stations are often underground or elevated, so accessibility there is not a question of providing low-floor vehicles, but providing a step-free access from street level to
2664-408: 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
2775-510: 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
2886-409: 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
2997-447: A text interface for a speech synthesizer for complete vocal disability. This can be a great improvement for people that have been limited to the use of a throat vibrator to produce speech since the 1960s. Usability Usability can be described as the capacity of a system to provide a condition for its users to perform the tasks safely, effectively, and efficiently while enjoying the experience. In software engineering , usability
3108-405: 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,

More than 400,000 wheelchair users in England were living in homes which are neither adapted nor accessible. Under the Convention on the Rights of Persons with Disabilities , states parties are bound to assure accessible elections , voting , and voting procedures. In 2018,
3330-504: 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

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,
4218-503: 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,
4329-621: 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
4440-431: 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

Accessibility modifications that allow ageing in place are becoming more common. Housing may even be designed to incorporate accessibility modifications that can be made throughout the life cycle of the residents. The English Housing Survey for 2018/19 found only 9% of homes in England have key features, such as
5217-463: Is the extent to which a product (such as a device, service, or environment) can be used by specified users to achieve specified goals with effectiveness, efficiency, and satisfaction in a specified context of use. Accessibility is also strongly related to universal design , the process of creating products that are usable by the widest possible range of people, operating within the widest possible range of situations. Universal design typically provides
5328-446: Is unattainable by traditional company-oriented market research . For example, after observing and interviewing users, 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

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

7659-440: 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
7770-537: 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.

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
9102-480: 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
9213-594: 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
9324-463: The needs of the driver. Ergonomic adaptations, such as a lumbar support cushion, may also be needed. Generally, the more limiting the disability, the more expensive the adaptation needed for the vehicle. Financial assistance is available through some organizations, such as Motability in the United Kingdom, which requires a contribution by the prospective vehicle owner. Motability makes vehicles available for purchase or lease. When an employee with
9435-408: The passenger cabin is unobstructed from one or more entrances by the presence of steps, enabling easier access for the infirm or people with push chairs . A further aspect may be that the entrance and corridors are wide enough to accommodate a wheelchair. Low-floor vehicles have been developed for buses , trolleybuses , trams and trains . A low floor in the vehicular sense is normally combined in
9546-458: The platforms (generally by elevators , which may be restricted to disabled passengers only, so that the step-free access is not obstructed by non-disabled people taking advantage). In the United Kingdom , local transport authorities are responsible for checking that all people who live within their area can access essential opportunities and services, and where gaps in provision are identified
9657-520: 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
9768-585: The public has led to some technological innovations. Public announcement systems using audio induction loop technology can broadcast announcements directly into the hearing aid of anyone with a hearing impairment, making them useful in such public places as auditoriums and train stations. The UN Convention on the Rights of Persons with Disabilities (2006) requires ‘appropriate measures’ to ensure people with disabilities are able to ‘access, on an equal basis with others','the physical environment’, ‘transportation’ and ‘other facilities and services open or provided to
9879-1181: The public sector and a large number of the reserved positions continue to be vacant despite nearly two decades of enactment of the PWD Act". Expenses related to adaptive or assistive technology required to participate in the workforce may be tax deductible expenses for individuals with a medical practitioner's prescription in some jurisdictions. Disability management (DM) is a specialized area of human resources that supports efforts of employers to better integrate and retain workers with disabilities. Some workplaces have policies in place to provide "reasonable accommodation" for employees with disabilities, but many do not. In some jurisdictions, employers may have legal requirements to end discrimination against persons with disabilities . It has been noted by researchers that where accommodations are in place for employees with disabilities, these frequently apply to individuals with "pre-determined or apparent disabilities as determined by national social protection or Equality Authorities", which include persons with pre-existing conditions who receive an official disability designation. One of
9990-409: The public’’. This requirement also applies to ‘roads’ and ‘transportation’ as well as ‘buildings, and other indoor and outdoor facilities’. At the same time, promotion of active travel , or 'shared space' initiatives to pedestrianise city centres can introduce unintended barriers, especially for pedestrians who are visually impaired and who can find these environments confusing or even dangerous. It
10101-418: 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
10212-468: 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
10323-849: The railroad ran dinner service on the Falmouth Line via North Falmouth. This Railroad should not be confused with, although is affiliated with, the Massachusetts Coastal Railroad - the freight railroad that transports trash off of the Cape. Since 2006, the Cape Cod Central Railroad has been a wholly owned subsidiary of Cape Rail Inc. , which also owns and operates the Massachusetts Coastal Railroad. In October 2012, Chicago-based Iowa Pacific Holdings acquired control of Cape Rail Inc. , and its subsidiaries, Massachusetts Coastal Railroad, LLC and Cape Cod Central Railroad. Despite
10434-414: 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
10545-412: The same time 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
10656-490: The same tools, services, organizations and facilities as non-disabled people (e.g., museums ). Article 9 of the United Nations Convention on the Rights of Persons with Disabilities commits signatories to provide for full accessibility in their countries. While it is often used to describe facilities or amenities to assist people with impaired mobility, through the provision of facilities like wheelchair ramps ,
10767-405: 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
10878-508: The streamlining of their accessibility services, allowing passengers requiring assistance to inform the company with as little as 10 minutes' notice at all 189 stations on its network, replacing an older scheme wherein assisted journeys had to be booked six hours to a day in advance. The system will utilise clear signage at stations and QR codes , allowing customers to send details of the assistance they require and their planned journey to staff remotely. Making public services fully accessible to
10989-444: 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
11100-447: 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
11211-481: 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
11322-777: The term can include other types of disability. Accessible facilities therefore extend to areas such as Braille signage, elevators , audio signals at pedestrian crossings , walkway contours, website accessibility and accessible publishing . In the United States, government mandates including Section 508, WCAG, DDA are all enforcing practices to standardize accessibility testing engineering in product development. Accessibility modifications may be required to enable persons with disabilities to gain access to education, employment, transportation, housing, recreation, or even simply to exercise their right to vote. Various countries have legislation requiring physical accessibility which are (in order of enactment): Legislation may also be enacted on
11433-477: 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
11544-516: The tires enables wheelchair users to move over soft surfaces, such as deep snow on ski hills, and sandy beaches. Assistive technology and adaptive technology have a key role in developing the means for people with disabilities to live more independently, and to more fully participate in mainstream society. In order to have access to assistive or adaptive technology, however, educating the public and even legislating requirements to incorporate this technology have been necessary. The UN CRPD, and courts in
11655-542: 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
11766-439: The use of a keyboard and mouse difficult or impossible. Technological improvements such as speech recognition devices and software can improve access. A communication disorder interferes with the ability to produce clearly understandable speech. There can be many different causes, such as nerve degeneration, muscle degeneration, stroke, and vocal cord injury. The modern method to deal with speaking disabilities has been to provide
11877-475: The user-driven or participatory design paradigm, some of the users become actual or de facto members of 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
11988-408: 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
12099-559: The way to Buzzards Bay and sometimes all the way into Rochester, but these trains usually do not stop at any stations after departure. Despite not having formal stations, select trains also stop at the Pairpoint Glass facility in Sagamore, and select dinner trains also depart from Falmouth. 41°42′25″N 70°22′27″W / 41.70694°N 70.37417°W / 41.70694; -70.37417 Accessibility Accessibility
12210-481: 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
12321-522: The workplace, and in school, expanding the ability of the user to participate in various spheres of daily life. Augmentative and alternative communication technology is one such area of IT progress. It includes inventions such as speech-generating devices , teletypewriter devices, adaptive pointing devices to replace computer mouse devices, and many others. Mobile telecommunications devices and computer applications are also equipped with accessibility features. They can be adapted to create accessibility to
