Microsoft's SenseCam is the key image capture tool for the MyLifeBits project, a lifetime storage database. SenseCam was invented by Researcher Lyndsay Williams of Microsoft Research Cambridge, UK in 1999. Early team members were James Srinivasan and Trevor Taylor. Williams left Microsoft in May 2007 and set up Girton Labs in Cambridge.
This research prototype of a wearable camera will contribute to an easier way of collecting and indexing one’s daily experiences by unobtrusively taking photographs whenever the internal sensor is triggered by a change in temperature, movement, or lighting.

Microsoft's SenseCam is the key image capture tool for the MyLifeBits project, a lifetime storage database. SenseCam was invented by Researcher Lyndsay Williams of Microsoft Research Cambridge, UK in 1999. Early team members were James Srinivasan and Trevor Taylor. Williams left Microsoft in May 2007 and set up Girton Labs in Cambridge.
This research prototype of a wearable camera will contribute to an easier way of collecting and indexing one’s daily experiences by unobtrusively taking photographs whenever the internal sensor is triggered by a change in temperature, movement, or lighting. In addition, the trigger can be disabled and set to go snap photos in a timer mode. The Sensecam is also equipped with an accelerometer, which will stabilise images so as to reduce blurriness. The camera can be worn around the neck or attached to one's belt or pocket.
The photos represent almost every experience of its wearer's day. They are taken via a wide-angle "fish-eye" lens in order to capture an image that is likely to contain most of what the wearer can see. The SenseCam uses a FLASH memory which has the means to store upwards of 2,000 photos per day as .jpg files. These files can then be uploaded and automatically formatted into a filmstrip. These daily movies can be easily reviewed and indexed using a custom viewer application running on a PC. Images can be played back at many frames per second (e.g. 3-10 fps), a technique termed Rapid Serial Visual Presentation (RSVP). It is possible to replay the images from a single day in as little as a few minutes.
Projections
Microsoft Research has contributed a device that will aid life bloggers among several other potential users. Sensecam was first developed to help people with minor memory loss, but the camera is currently being tested to aid those suffering with serious cognitive memory loss. The SenseCam produces images which are very similar to one's memory, particularly episodic memory, which is usually in the form of visual imagery. By reviewing the day's filmstrip, patients suffering from Alzheimer's, amnesia, and other memory impairments found it much easier to retrieve lost memories.
Microsoft Research has also tested internal audio level detection and audio recording for the SenseCam, although there are no plans to build these into the research prototypes at the moment. 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 in social phenomena, monitoring food intake, and assessing an environment's accessibility for the handicapped.
