- AI Overreliance(also: Automation Bias, Over-Trust in AI)
- The tendency for users to trust AI systems more than is warranted by their actual accuracy, accepting AI-generated outputs without sufficient critical evaluation. In accessibility contexts, AI overreliance is a significant safety concern because blind and low vision users of…
- AI Trust Calibration(also: Trust Calibration, Appropriate Trust)
- The process of aligning a user's level of trust in an AI system with the system's actual reliability and capabilities. In accessibility contexts, trust calibration is critical because blind and low vision users of AI-powered visual access tools tend to over-trust AI-generated…
- AccessiWeb(also: AccessiWeb Reference List)
- A French web accessibility methodology and reference list developed by BrailleNet, providing a practical application framework based on WCAG. AccessiWeb translates WCAG success criteria into testable criteria organized for use in conformance audits, quality assurance, and…
- Adversarial Stakeholders
- Individuals, institutions, or systems that disabled people depend on for access but that simultaneously pose threats of harm. Examples include healthcare providers who discriminate based on stigmatized identities, government agencies that condition benefits on compliance, or…
- Emotional Accessibility(also: Psychological Accessibility)
- The consideration of emotional and psychological impacts in accessibility design, recognizing that inaccessible technology affects not only task completion but also users' confidence, autonomy, stress levels, and overall well-being. Emotional accessibility extends traditional…
- Human-Centered Threat Modeling
- A methodology borrowed from security and privacy research that identifies the people and institutions who intend to cause harm to a specific population, the threats they pose, and the defensive strategies the population uses. In accessibility research, human-centered threat…
- Inclusive Design Process
- A design approach that intentionally includes diverse users, particularly those with disabilities and from marginalized communities, throughout all stages of product development. An inclusive design process goes beyond accessible materials to consider the entire ecosystem of…
- Semantic Level(also: Semantic Content Level, Alt Text Semantic Level)
- A framework for categorizing the depth of information conveyed in alt text descriptions of data visualizations, introduced by Lundgard and Satyanarayan. The four levels are: Level 1 (construction details such as chart type, axes, and encodings), Level 2 (statistical properties…
- Stable Systems of Access
- Access ecosystems where a disabled person can reliably anticipate available resources, plan long-term, and accumulate stability over time. In a stable system, stakeholders are predictable, resources are consistently available, and the person can make informed decisions about…
- Systems of Access
- A conceptual framework describing the dynamic network of people, institutions, environments, and resources that disabled people navigate to meet their needs. Unlike linear models of accessibility that focus on removing individual barriers, systems of access recognizes that…
- Unstable Systems of Access
- Access ecosystems characterized by unpredictability, where resources and stakeholder relationships may shift without warning, forcing reactive decision-making and increasing risk. In unstable systems, a disabled person struggles to anticipate future resources and relationships,…
- User-Centered Design(also: UCD, Human-Centered Design)
- A design philosophy and process that places the needs, preferences, and limitations of end users at the center of each stage of the design process. In accessibility contexts, user-centered design means actively involving people with disabilities not just as test subjects…
