AI Homogenization(also: AI-Driven Homogenization, Generative AI Homogenization Effect)

The tendency for generative AI systems to produce outputs that converge toward similar patterns, reducing the diversity and uniqueness of results across different users and contexts. In accessibility and assistive technology, AI homogenization is particularly concerning because…

Breadcrumb(also: Breadcrumb Navigation, Breadcrumb Trail, Breadcrumbs)

A secondary navigation pattern that displays the user's current location within a site or application hierarchy as a series of linked steps, typically separated by arrows or slashes. Breadcrumbs help users understand where they are in a structure and navigate back to higher…

Cognitive Scaffolding(also: Scaffolded Support, Guided Task Support)

External supports or structures that help a person complete cognitive tasks they might not be able to manage independently. In education, scaffolding refers to temporary supports removed as competence grows; in accessibility, it often means persistent supports embedded in…

Disability Dongle

A term coined by disability advocate Liz Jackson describing a well-intentioned but ultimately useless technology solution created for disabled people by non-disabled people who have not engaged with the community they intend to serve. Disability dongles are typically conceived…

Participatory AI(also: Community-Centered AI, Participatory Machine Learning)

An approach to artificial intelligence development that actively involves the communities affected by AI systems in defining problems, setting priorities, designing solutions, collecting data, evaluating outcomes, and governing deployment. Participatory AI goes beyond…

Task Decomposition(also: Task Breakdown, Chunking Tasks)

The process of breaking a large, complex, or overwhelming task into smaller, manageable steps that can be completed sequentially. Task decomposition is a critical cognitive accessibility strategy for people with executive dysfunction, as large undifferentiated tasks create…

Visual Clutter(also: Visual Noise, Visual Complexity)

An excess of visual elements in an environment or interface that makes it difficult to locate, identify, or focus on relevant information. Visual clutter is a significant barrier for people with cerebral visual impairment, simultanagnosia, and other visual processing conditions,…
