A SenseCam browser (Microsoft). A wearable device that takes a picture every 22 seconds. Hodges et al (2006)
- Tools for lifelogging
- Hundreds of thousands of images grabbed and presented to aid memory … and memory rehabilitation.
- Automatic content analysis techniques
(There is a reason why we forget. The quote from James on the need to spend as much time recalling the record if everything is remembered is like that of Lewis Carroll and a map the size of the real world – neither had the advantage of limitless digital storage capacity and the ability to zoom in and out or back and forth – to expand time, not simply record it.).
- A visual record of your day. Berry et al (2007)
- 2000 to 5000 images a day
Best practice
- Only activate the device for significant events
Methods of review
- Clustered time view
- Geographical map (required GPS)
- Interactive story authoring
- Motion sensors identify events – typically 20-30 in a day.
PROBLEMS
- Cognitive overload
- Keyframe image selection a human endeavour
- An entusiastic lifelogger might expect to gather 100,000 images a month.
OF NOTE
- Key frame selection only of note if it picked a poor image.
