概要	Online participant observation is a qualitative data collection method in which the researcher enters a digital community or online environment — forums, social media groups, multiplayer games, virtual workplaces — both as a participant and as an observer, systematically documenting social interactions, practices, and meanings as they naturally unfold in the digital space.	Non-participant observation is a data-collection method in which the researcher observes behavior, interactions, or events in a natural or structured setting without joining or influencing the activity under study. The observer maintains a deliberate distance from participants to minimize their own effect on the phenomena being recorded, producing field notes, behavioral tallies, or recordings that reflect naturally occurring behavior rather than behavior shaped by researcher involvement.
