概要	Face-to-face field notes are a foundational qualitative data collection technique in which the researcher is physically present in the setting and records observations, interactions, events, and contextual details in written form. As the canonical mode of ethnographic and observational research, in-person field notes capture the social texture, nonverbal cues, spatial arrangements, and moment-to-moment dynamics of real-world settings that remote or mediated data collection cannot fully replicate.	The diary method is a data-collection technique in which participants record their thoughts, behaviours, events, or experiences in their own words at regular or event-contingent intervals over a defined study period. By capturing data close in time to the event, diaries reduce retrospective recall bias and give researchers access to the texture of everyday life as it unfolds — something one-off surveys and retrospective interviews cannot provide.
