Participants wear miniature video cameras in a pair of glasses, known as “subcams”, as they perform their ordinary activity (e.g. parenting, eating, shopping, playing, painting, nursing, piloting nuclear plants etc.) in their natural setting (the researcher is not present).
The device itself, the subcam worn by participants is unobtrusive. Participants declare forgetting it after a few minutes and behaving as usual, while other people usually don’t even notice the subcam. They act naturally as they are taken in the flow of action or usual routine. Privacy and image right are protected by a specific ethics protocol that guarantees participants full control over the recordings.
The films produced provide a remarkably precise and accurate account of what the participants did, saw, heard, said etc., captured from their own perspective in high-definition and stereo.
