概要	Online Mobile Experience Sampling (Online ESM) is a data collection technique that uses internet-connected smartphones or tablets to prompt participants multiple times per day and record their thoughts, feelings, behaviors, and context in the moment they occur. By gathering data in real time across daily life rather than retrospectively in a lab, it dramatically reduces recall bias and captures the natural variation of psychological and behavioral states as they unfold.	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.
