Summary

During a field study, a participant wears a sensor that registers their physical states. User's mobile phone logs the activities on the phone. The data from both sources is combined to scraps of person's life. The scraps data is presented to the participant who can scribble their reflected thoughts on them.

Strengths

Psycho-physiological measurements are taken as part of a field study, and combined with activity data plus user's own comments on the recorded events.

Weaknesses

Needs expensive equipment.
Analysis is laborious.
