SenseCam is a wearable digital camera that is designed to take photographs passively, without user intervention, while it is being worn.Unlike a regular digital camera or a cameraphone, SenseCam does not have a viewfinder or a display that can be used to frame photos. Instead, it is fitted with a wide-angle (fish-eye) lens that maximizes its field-of-view. This ensures that nearly everything in the wearer’s view is captured by the camera, which is important because a regular wearable camera would likely produce many uninteresting images.
SenseCam also contains a number of different electronic sensors. These include light-intensity and light-color sensors, a passive infrared (body heat) detector, a temperature sensor, and a multiple-axis accelerometer. These sensors are monitored by the camera’s microprocessor, and certain changes in sensor readings can be used to automatically trigger a photograph to be taken.

Don't laugh. Things go from geek to chic very quickly these days. Think about it. How often do you refer to your calendar program to remember what you did, when? Surveillance devices like this one will eventually become standard gear. ~Kevin
