One of my ideas for the cultural probe is a day-in-your-life diary that allows participants to convey details about their daily life. Participants may be requested to document each time they engage in a particular behaviour, encounter a product or situation, or have a specific type of interaction. I showed some of my test diaries to Daniel to get some feedback. He preferred the one that was split into 3-hourly blocks to the one that had no designated time allocation. He said that with 3-hourly blocks he could fill in the activities in bulk after three hours, rather than remembering to fill in each activity straight after it happened. He also pointed out that asking uni students, for example, to test the diary might not work because they lead quite different lives to my target users.
