Interaction Analysis

A qualitative research method for studying knowledge and action in interaction with people, objects, and environments — typically through close observation of video or screen recordings, annotating visible affect, body language, utterances, and moment-by-moment behavior. Developed by Jordan and Henderson, interaction analysis is widely used in HCI accessibility research to surface how users actually navigate interfaces, where breakdowns occur, and what support they rely on. It complements thematic and content analysis by capturing embodied, situated behavior that interview data alone cannot reveal.
