This paper describes a Visualization-Assiste photo elicitation techniques. The authors’ main argument is that photo elicitation interviews can be helped with visualization because people tend to forget the context in which a picture was taken.

They developed MMM2, a multimedia system that help organizing a collection of pictures and produces different visualization, organized by time, or by sharing recepient or source.

Using the visualizations, interviewee could better recall the contextual information at the time the picture was taken. Also the evidence sometimes refreshed or contracticted the participants’ memories. Third, patters of use, of which the participants were unaware, became apparent, revealing important events, or lacunae of activity.
