"A small digital camera developed by Microsoft Research could boost memory in people with dementia and possibly mild forms of Alzheimer's disease. SenseCam is worn around the neck and automatically takes a wide-angle, low-resolution photograph every 30 seconds. It contains an accelerometer to stabilize the image and reduce blurriness, and it can be configured to take pictures in response to changes in movement, temperature, or lighting. An entire day's events can be captured and downloaded onto a PC where software converts the pictures into a short movie displaying the images at up to 10 frames per second, to allow patients to view a day's events in a few minutes to jolt their memory. "Not only does SenseCam allow people to recall memories while they are looking at the images, which in itself is wonderful, but after an initial period of consolidation, it appears to lead to long-term retention of memories over many months, without the need to view the images repeatedly," says neuropsychologist Emma Berry."
