概要	The online diary method is a longitudinal data collection technique in which participants record their thoughts, experiences, behaviors, or events in structured or semi-structured entries submitted via digital platforms — such as web forms, email, or dedicated apps — at regular or event-contingent intervals. It combines the ecological validity of traditional diary research with the logistical advantages of remote, automated data collection.	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.
