Inequitable Access(also: Inadequate Accommodation)
Inequitable access describes the situation where accommodations or accessibility measures are provided but fail to adequately address the underlying inaccessibility, leaving people with disabilities with access that is significantly inferior to what nondisabled people…
Infrastructuring for Access
A design approach introduced by Wang and Marie (CHI 2026) that combines HCI's infrastructuring theory with Disability Studies and Repair Studies. Rather than focusing on removing barriers or accommodating individual users, Infrastructuring for Access treats disabled…

Interdependent Accessibility(also: Interdependence Framework, Access Interdependence)

Internalized stigma(also: Self-stigma, Internalized ableism)
The process by which individuals with disabilities or neurodivergent conditions absorb and internalize negative societal attitudes about their condition, leading to shame, reduced self-worth, and reluctance to seek support. Internalized stigma can manifest as viewing one's…
Interpretive phenomenological analysis(also: IPA)

A theoretical framework originated by Kimberlé Crenshaw recognizing that individuals hold multiple social identities (disability, race, gender, class, sexuality) that interact to produce unique experiences of privilege and oppression that cannot be understood by examining any…
Intra-sectionality(also: Intra-sectional Analysis)
The examination of variation and diversity within a single identity category or demographic group, as opposed to intersectionality which examines the interaction between different identity categories. In disability research, intra-sectionality reveals that people within a single…
Invisible Work(also: Invisible Labour, Hidden Work)
