This document provides an overview of 'point of view surveillance' (PoVS) technologies, as a basis for considering their applications, impacts and implications. The first section provides a very brief overview of surveillance technologies as a whole.
A brief review of the development of surveillance practices is provided in (Clarke 2001), and a set of vignettes is in Clarke (2007b). During a 25-year period studying many aspects of surveillance, the author has developed a Framework for the Analysis of Surveillance (Clarke 2009). It has three elements:
The term 'point of view surveillance' is of recent origin, and is used to describe several capabilities that have seen rapidly increasing intensity of deployment in the last few years. In terms of the classifications outlined in the previous section, PoVS is inherently Aided Physical Surveillance, and specifically Visual, although quite probably Audio as well, and in some circumstances perhaps Audio-only. Particular applications also incorporate Location and Tracking surveillance technologies.
The defining feature of PoVS is that the camera is human-borne, and points away from the human, generally following the orientation of the person's head, i.e. to capture the scene in the person's line-of-sight, or point-of-view. Means of carriage include eyepieces, spectacle-frames, headbands and helmets.
These defining features differentiate PoVS from:
The term 'wearable computing' has been in use since at least 1980, when Steve Mann applied it in particular to wearable cameras and head-mounted displays (Mann 1996, 1997). More generally, see Rhodes (1997).
The usage of PoVS may be overt, or covert, or not intentionally covert but non-obvious. As a result of the miniaturisation of cameras, some worn-cameras are inherently non-obvious.
Recording and transmission may be continuous, may be instigated by the individual or by another person remotely, or may be automatically triggered, e.g. by a motion-detector or accelerometer.
A strict definition limits PoVS to a camera closely associated with a person's head, such that it changes its direction when the person turns their head, and hence is always capturing the scene from that person's point-of-view.
However, the term PoVS is used with some looseness, to also encompass at least the following:
The basic and extended definitions provided in the previous section specify the ability to capture a still-image or a moving-image.
PoVS devices may be designed with a range of further capabilities, including:
The use of PoVS technology to replace a person's direct vision with a video-feed appears, by itself, to offer the person little or no advantage. However, it opens up a range of possibilities. In particular:
Some examples of augmented displays include:
Up to this stage in the development of the notion of PoVS, it has been described as a single feed from a single point-of-view, which may be fed locally to the person, recorded locally, transmitted and/or recorded remotely.
The scope exists, however., for multiple points-of-view to be exploited. Multiple feeds can be transmitted to the same place, or in such a manner that the feeds, or the recordings, can be acquired by multiple parties.
The range of possibilities can be readily appreciated using the (all-too-common) scenario of a major demonstration, with confrontations between law enforcement staff and demonstrators, and recriminations on both sides.
The law enforcement command and control centre might display multiple points-of-view, transmitted from policemen's kit, in parallel. This may provide a better sense of the overall situation, and enable more effective deployment of resources. In addition, the running of synchronised recordings, with synchronised slow, stop-start and rewind functionality, may enable more effective retrospective investigation of what occurred in a particular place at a particular time.
Given the recent, dramatic changes in the economics of PoVS technologies, video transmission and command-and-control centres, the demonstration-organiser might do much the same as the law enforcement agency, using transmissions from demonstrators' mobile-phones.
Applying the principles of 'crowd-sourcing', volunteers might provide feeds, intended for any and all of law enforcement agencies, the demonstration-organiser, a human rights observer organisation and/or to a publicly-available site, as suggested by the 'Transparent Society' hypothesis (Brin 1998).
To the extent that private feeds or recordings exist, the law enforcement agency, the demonstration-organiser, a human rights organisation and/or individuals concerned about the matter, might seek access to them using warrants and/or demand-powers on one side, and, on the other, requests, FOI requests and hacking.
A number of surveillance technologies share a variety of features with PoVS, and discussions frequently use the PoVS term even more loosely to include some or all of them. Examples include:
