Curb cut effect

The curb-cut effect

The curb-cut effect illustrates how when we design to benefit disadvantaged or vulnerable groups we end up helping society as a whole. Angela Glover Blackwell explains how campaigning by students with disabilities in Berkeley in the early 1970s led to adding curb cuts to the Berkeley sidewalks to make access easier for those in wheelchairs. Yet it wasn't just people in wheelchairs that it helped. Curb cuts also made life easier for people pushing children in strollers, people using trolleys for deliveries, people pulling a suitcase, those wheeling bikes or on skateboards, and it also helps save lives by guiding people to cross at safe locations. Another example is adding closed captioning to TV that helps anyone watch in a noisy bar, a waiting room, or watching an airline safety video. Or a classic example of universal design in the OXO Good Grips range originally made to be comfortable for holding a peeler even if you have arthritis. It's also a useful analogy for "how laws and programs designed to benefit vulnerable groups, such as the disabled or people of color, often end up benefiting all," (PolicyLink) whether that be increasing broadband access, improving public transport or taking cuts out of curbs. Here's a short, fun video of Gary Karp explaining the curb-cut effect. Thanks to my patron Quintin Balsdon for sharing it with me.

Digital accessibility is real and tangible

A workshop using real-life examples and first-hand experience of how assistive technology works can result in a deeper understanding of accessibility needs

The influence of artificial intelligence on individuals with disabilities

The rapid advancement of artificial intelligence (AI) is reshaping assistive technologies, offering new possibilities for enhancing the independence, communication and quality of life of individuals with disabilities. This study presents a qualitative scoping review of 47 peer-reviewed articles published between 2018 and 2025, examining how AI has been integrated into assistive tools across domains such as mobility, communication, cognitive support, education and independent living. Specific AI applications include object recognition, gesture-based control, navigation assistance, emotion detection and natural language processing. The review highlights significant progress in personalization and real-time adaptation, while also identifying persistent challenges such as algorithmic bias, cost barriers, data privacy concerns and unequal access, particularly in low-resource settings. Ethical considerations and the need for inclusive, user-centered design approaches are emphasized. The study also underscores future research priorities, including standardization of development protocols, empirical evaluation of long-term effectiveness and policy frameworks to ensure equitable access. By synthesizing recent developments and critical gaps, this review contributes to understanding how AI can responsibly and effectively support assistive technologies, ultimately promoting more inclusive environments for people with disabilities.

Rethinking the "disabled norm": 7 patterns to use instead in your design system - zeroheight

Chela Giraldo explains how disabled states harm accessibility and what to do instead to build clearer, more inclusive user interfaces.

Substrates via Accessibility

The social model of disability holds that disability is produced by environments, not by bodies — that when software fails to accommodate a person’s needs, the environment is disabling them. We argue that the dominant organization of computing produces such interaction mismatches structurally: the commodity form of software requires a standardized consumer, and everyone whose needs diverge from this imagined subject is disabled by the software environment. The substrates research community has identified properties — disclosure, composability, malleability — that would address this, but the commodity form actively selects against these properties because they dissolve the boundaries on which exchange value depends. This raises a question: how can infrastructure organized against the grain of commodity logic be made durable? We find a precedent in accessibility infrastructure — sustained not by patronage but by the organized counter-power of disability rights movements. Through Allio, a system for cross-application augmentation built on accessibility APIs, we illustrate both what this foundation makes possible and where its limits lie. We argue that the accessibility case reframes the substrates programme’s central challenge as political-economic: the question of who sustains substrate infrastructure, and through what social mechanisms, is as important as the question of what properties it should have.

Crip Technoscience Manifesto

As disabled people engaged in disability community, activism, and scholarship, our collective experiences and histories have taught us that we are effective agents of world building and dismantling toward more socially just relations.The grounds for social justice and world remaking, however, are frictioned;technologies, architectures, and infrastructures are often designed and implemented without committing to disability as a difference that matters. This manifesto calls attention to the powerful, messy, non-innocent, contradictory, and nevertheless crucial work of what we name as “crip technoscience,” practices of critique, alteration, and reinvention of our material-discursive world. Disabled people are experts and designers of everyday life. But we also harness technoscience for political action, refusing to comply with demands to cure, fix, or eliminate disability. Attentive to the intersectional workings of power and privilege, we agitate against independence and productivity as requirements for existence. Instead, we center technoscientific activism and critical design practices that foster disability justice.
