- In-situ Study (In-situ evaluation, Field study)
- A user study conducted in the real-world setting where the technology would actually be used (a museum floor, a corridor with passersby, a commuter train), rather than in a controlled lab or via remot…
- Inclusive Co-Design (Inclusive Participatory Design)
- A design methodology that ensures people from typically marginalized groups, including people with intellectual disabilities, are meaningfully included throughout the technology design process as equa…
- Inductive Thematic Analysis (Bottom-Up Thematic Analysis)
- A qualitative data analysis method where themes and patterns are identified directly from the data without being guided by pre-existing theoretical frameworks or hypotheses. In inductive thematic anal…
- Information Quality (IQ, Data Quality)
- A measure of how well information meets the needs of its consumers, encompassing dimensions such as accuracy, completeness, currency, relevance, and reliability. In accessibility and disability contex…
- Inter-Rater Reliability (Inter-Coder Reliability, Inter-Annotator Agreement, IRR)
- A statistical measure of the degree to which two or more independent raters or coders agree in their assessments or classifications of the same data. In accessibility research, inter-rater reliability…
- Interpretive phenomenological analysis (IPA)
- A qualitative research methodology focused on exploring how people make sense of their lived experiences, widely used in accessibility and disability research. IPA involves detailed analysis of indivi…
- Intra-sectionality (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.…
- Intrinsic Motivation Inventory (IMI)
- A standardized psychometric instrument used to assess participants' subjective experience during activities, measuring dimensions such as interest/enjoyment, perceived competence, effort/importance, v…
- Journey Mapping (Journey Map)
- A qualitative research and design method in which participants describe a trip, task, or experience step-by-step across sequential phases (e.g., pre-trip, in-trip, post-trip), identifying the tools th…
- Latin Square Design (Latin Square Counterbalancing)
- A counterbalancing method used in experimental research to control for order and sequence effects when each participant experiences multiple conditions. In a Latin Square arrangement, conditions are o…
- Levenshtein Distance (Edit Distance)
- A metric that measures the minimum number of single-character edits (insertions, deletions, and substitutions) needed to transform one string into another. In accessibility research, Levenshtein dista…
- Likert Scale (Likert-Type Scale)
- A psychometric rating scale commonly used in surveys and usability studies where respondents indicate their level of agreement or satisfaction on a symmetric scale, typically with 5 or 7 points rangin…
- Low-Fidelity Prototyping (Lo-Fi Prototyping, Paper Prototyping)

- Low-Incidence Disability (Low-Prevalence Disability)
- A disability that occurs relatively rarely in the general population, such as blindness, deafblindness, or certain developmental conditions. Low-incidence disabilities present unique challenges for re…
- Mediated Communication (Proxy Communication, Supported Communication)
