AI Verification(also: Accessible AI Verification, AI Output Verification)

The process of checking and confirming the accuracy of AI-generated output, particularly by end users who may not have visual access to the original content. For blind users, AI verification is challenging because they cannot visually compare AI output against source material.…

Access to Information(also: Information Access)

In the context of web accessibility, the concept that certain accessibility criteria are fundamentally about whether users can reach and perceive content at all, as distinct from criteria that improve the quality or experience of that access. Access to information serves as a…

Accessibility(also: A11y)

The design of products, devices, services, environments, and systems so that they can be used by people with the widest range of abilities, including those with disabilities. In digital contexts, accessibility means ensuring websites, applications, and content are perceivable,…

Accessibility Allyship(also: Disability Allyship, A11y Allyship)

The practice of non-disabled individuals actively supporting and advocating for people with disabilities by learning about accessibility barriers, amplifying disabled voices, and taking concrete actions to create more inclusive environments. In technology and computer science…

Accessibility Chain(also: Accessibility Chain of Custody, Chain of Accessibility)

The concept that accessibility must be maintained throughout every link in a sequence of interactions, documents, or systems that a user must navigate to complete a task. If any single link in the chain is inaccessible, the entire process becomes inaccessible regardless of how…

Accessibility First(also: Shift Left Accessibility, Built-In Accessibility)

A design and pedagogical philosophy that treats accessibility as a foundational requirement from the very beginning of a project or course of study, rather than addressing it as an advanced topic or retrofit at the end. The term draws an analogy to building construction:…

Accessibility Retrofitting(also: Retrofitting, Accessibility Remediation)

The process of modifying existing products, websites, buildings, or systems after the fact to make them accessible to people with disabilities. Retrofitting is typically more expensive, time-consuming, and less elegant than designing for accessibility from the start, often…

Accessibility Workaround(also: A11y Workaround, Assistive Workaround)

An alternative method, process, or tool that people with disabilities develop or adopt to accomplish tasks that are blocked by inaccessible design. Workarounds represent the hidden labor that disabled people must invest to navigate inaccessible systems — creating parallel…

Age-Related Capability Decline(also: Age-Related Impairment, Dynamic Diversity)

The gradual reduction in sensory, motor, and cognitive capabilities that typically accompanies ageing, including declining visual acuity, hearing loss, reduced dexterity and fine motor control, and changes in memory and processing speed. Unlike many disabilities that are stable…

Age-Related Functional Limitations(also: Ageing-Related Accessibility Needs, Age-Related Impairments)

The gradual changes in sensory, motor, and cognitive abilities that commonly occur with ageing, including declining vision, hearing loss, reduced dexterity and fine motor control, and changes in memory and processing speed. These functional limitations often overlap…

Age-Sensitive Design(also: Age-Sensitive Creative AI Mediation)

A design stance that treats age-related physical, cognitive, and digital-literacy characteristics as first-class inputs to the system design process rather than as edge cases to be handled after the fact. For interactive and AI-supported tools, age-sensitive design typically…
