Well, thank you Jeff for this very informative summary of mobile research/design methods! It is actually a comparison of methods for understanding mobile behavior to inform technology design: Case Studies, Diary Studies, Cultural Probes, Ethnography, Field Study (natural or artificial settings), Interviewing, Lab experiment, Normative writings, Survey research, Techology Probes. Trying to find mysefl in the picture, I am actually doing a kind of 'lab experiment/light field study in artifical settings'.
