Diary Study

A longitudinal research method in which participants record their experiences, behaviors, and reflections over an extended period (days to weeks) while interacting with a system or technology in their natural environment. In accessibility research, diary studies are particularly valuable because they capture real-world usage patterns, challenges, and workarounds that may not emerge in controlled lab settings. Participants typically complete structured or freeform log entries after each interaction session, documenting what they did, what worked well, and what problems they encountered. Diary studies are often combined with follow-up interviews to explore themes that emerge from the entries. This method is well-suited for evaluating assistive technologies because it reveals how users integrate tools into their existing workflows over time rather than just measuring first-use performance.
