TL;DR
DiaryHelper is an automatic agent that aids participants in elicitation diary studies by capturing detailed contextual information, improving recall accuracy and depth without adding significant burden.
Contribution
We introduce DiaryHelper, a novel automatic contextual recording agent that enhances data quality in elicitation diary studies by leveraging episodic memory theory.
Findings
Participants recorded more detailed contextual information.
DiaryHelper improved recall accuracy during interviews.
Participants experienced minimal additional burden.
Abstract
Elicitation diary studies, a type of qualitative, longitudinal research method, involve participants to self-report aspects of events of interest at their occurrences as memory cues for providing details and insights during post-study interviews. However, due to time constraints and lack of motivation, participants' diary entries may be vague or incomplete, impairing their later recall. To address this challenge, we designed an automatic contextual information recording agent, DiaryHelper, based on the theory of episodic memory. DiaryHelper can predict five dimensions of contextual information and confirm with participants. We evaluated the use of DiaryHelper in both the recording period and the elicitation interview through a within-subject study (N=12) over a period of two weeks. Our results demonstrated that DiaryHelper can assist participants in capturing abundant and accurate…
