For this episode I spoke with Murray Goulden of the Horizon centre at the University of Nottingham and he told me about the projects he is working which, amongst other things, use digital traces as a memory aid as part of ethnographic research. To do this him and his colleagues have designed methods and technologies to extract data from people’s digital devices (with consent of course!) to present these data back to people. The participants were then encouraged to make sense of these data (which they wouldn’t usually see). You can follow Murray on Twitter @murraygoulden
