Accessibility: Human-Machine Interfaces

In course

Description

This lecture by the instructor covers the topic of accessibility in human-machine interfaces, focusing on alternative interfaces, the concept of disability, assistive technologies, and the principles of software accessibility. It also delves into the accessibility of documents, including basic rules and recommendations. The presentation emphasizes the importance of making digital content accessible to all users, regardless of their abilities, and provides insights into the dimensions of digital accessibility, the role of operating systems, applications, and document structuring. Practical guidelines for software accessibility and document creation are discussed, along with the significance of keyboard accessibility, providing feedback, and offering alternatives to non-text elements. The lecture concludes with a reflection on the societal impact of accessibility and challenges stereotypes related to age and technology use.

Accessibility

Accessibility is the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers). Accessibility can be viewed as the "ability to access" and benefit from some system or entity.

Web accessibility

Web accessibility, or eAccessibility, is the inclusive practice of ensuring there are no barriers that prevent interaction with, or access to, websites on the World Wide Web by people with physical disabilities, situational disabilities, and socio-economic restrictions on bandwidth and speed. When sites are correctly designed, developed and edited, more users have equal access to information and functionality.

Computer accessibility

Computer accessibility (also known as accessible computing) refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment. Computer accessibility often has direct positive effects on people with disabilities.

User experience

The user experience (UX) is how a user interacts with and experiences a product, system or service. It includes a person's perceptions of utility, ease of use, and efficiency. Improving user experience is important to most companies, designers, and creators when creating and refining products because negative user experience can diminish the use of the product and, therefore, any desired positive impacts; conversely, designing toward profitability often conflicts with ethical user experience objectives and even causes harm.

User experience design

User experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
