Which method consists of users tracking their activities over a period?

The method that involves users tracking their activities over a period is the Diary Study. In this approach, participants are asked to keep a detailed record of their activities, experiences, or behaviors over a specified time frame. This method allows researchers to gather qualitative data about users' interactions and feelings in a real-world context, providing insights into their habits, preferences, and challenges as they occur naturally over time.

Diary Studies are particularly valuable for understanding user experiences in depth because they capture the nuances and temporal dynamics of people's lives. It enables researchers to see patterns and trends that may not emerge from more static data collection methods like surveys or one-time interviews. This longitudinal aspect helps to create a richer understanding of the user journey and can inform design decisions to enhance user experience effectively.
