SenseCam

A wearable digital camera originally developed by Microsoft Research that automatically captures photos throughout the day without requiring the wearer to actively take pictures. SenseCam is worn around the neck and uses sensors (light level, temperature, passive infrared for detecting people, accelerometer for movement) to trigger photo capture at contextually appropriate moments, typically producing thousands of images per day. The device was designed as a lifelogging tool to create a visual diary of daily experiences, and has been extensively studied as a memory aid for people with episodic memory impairment, particularly those with Alzheimer's disease and other forms of dementia. Research has shown that reviewing SenseCam images can significantly improve memory recall for recent experiences. The device was later commercialised as the Vicon Revue and inspired subsequent wearable lifelogging cameras.
