Sousveillance: Implications for Privacy, Security, Trust, and the Law.

Point of view has its foundations in film. It usually depicts a scene through the eyes of a character. Body-worn video-recording technologies now mean that a wearer can shoot film from a first-person perspective of another subject or object in his or her immediate field of view (FOV). The term sousveillance has been defined by Steve Mann to denote a recording done from a portable device such as a head-mounted display (HMD) unit in which the wearer is a participant in the activity. Some people call it inverse surveillance because it is the opposite of a camera that is wall mounted and fixed.
