Microsoft's SenseCam is a lifelogging camera with a fisheye lens and trigger sensors, such as accelerometers, heat sensing, and audio, invented by Lyndsay Williams, a patent[1] granted in 2009.
[2] Wearable neck-worn cameras contribute to an easier way of collecting and indexing one's daily experiences by unobtrusively taking photographs whenever a change in temperature, movement, or lighting triggers the internal sensor.
Several studies have been published by Chris Moulin, Aiden R. Doherty and Alan F. Smeaton[4] showing how reviewing one's SenseCam images can lead to what Martin A. Conway, a memory researcher from the University of Leeds, calls "Proustian moments",[5] characterised as floods of recalled details of some event in the past.
The research team is also exploring the potential of including sensors that will monitor the wearer's heart rate, body temperature, and other physiological changes, along with an electrocardiogram recorder when capturing pictures.
Other possible applications include using the camera's records for ethnographic studies of social phenomena, monitoring food intake, and assessing an environment's accessibility for people with disabilities.
