In Feb this year, UK-based Vicon made the technology dubbed "Vicon Revue" available to researchers who study Alzheimer's disease and other conditions that affect short-term memory loss. Now, in August, Vicon will release the next-generation camera, the Revue 3MP.
The camera, which is about the size of a Post-It note, is worn on a cord around the neck and unlike ordinary digital cameras or camera phones, the Revue doesn't have a viewfinder or a display - it's equipped with a wide-angle, "fish-eye" lens that captures nearly everything in the wearer's field of vision. The camera can be set to a timer. But, more often than not, it's set to capture an image each time it senses a change in motion, light or temperature. In either case, images are captured without the user having to stop and take a photo themselves.
The end result is a series of hundreds, thousands, even tens of thousands of photos that are recorded on the device's internal memory and later loaded onto a computer. When reviewed, the photos act as a visual diary as shown in the video below.
The theory goes like this: because photos are taken in automated, fragmented way, and are taken from the users' point of view, looking back on the photos later can trigger memories in ways that ordinary photos can't.
Tests have shown that Revue photos enabled users to retrieve memories that would otherwise be lost. And the memories remained in their minds for weeks and months afterward.
In addition to aiding memory loss, Vicon points to other potential uses, including:
- Monitoring exercise, medication, food and alcohol intake
- Security, law enforcement, and military applications
- Emergency services
- Teaching and school projects
- Documentary making and art projects
- Market research
