Something like that would be neat, but one might want to limit the
amount of data collected depending on the application. If it was for a
person with memory problems, then maybe context sensitive devices
could cue in on moments during which to collect photos, sounds, &c.
I think these should also be mapped--and I wouldn't necessary want
things to require too much high tech gadgetry because I'd want to keep
costs down. If the problem domain is to assist patients, then a
caretaker could note typical routes on a map, perhaps record it in
whatever handheld device that would end up being used.
If picking up contextual cues to decide when to capture data is too
tricky of a problem to solve with limited resources, then the
caretaker could set waypoints in the route stored in the device.
Though, I don't think picking up contextual cues would be that
difficult. sensors are cheap, and I've thought about the problem
before with respect to drivers and cell phones, and the problem of
trying to determine how to get the users attention away from a
conversation during problematic traffic situations. (aside: if you get
a common protocol going for communication between the environment and
a device such as a phone, you could have rules for buildings such as
theatres, hospitals, planes, &c. which would negotate proper phone
ettiquite with the phone instead of the user)
Another thing a device could do is prompt a user to interact with the
environment and require this interaction in the creation of a tag
rather than using some automatic scheme. You'd assist people with
memory problems better in such a way since forcing them into an
elaborate rehearsal of a task rather than rote memorization is better.
You'd also be forcing them to make judgements about the environment.
This might help keep their brains agile. Even playing a song might be
good--I read an article once about how alzheimer patients might gain
benefit from singing.
Anyway, it's fun to think of these types of applications, and a
tagging/bookmark system is one part of them. though I suppose it would
junk up the del data to have this type of diagnostic or therapeutic
type of information going on with it. probably better to have a more
specialized repository, though I'd be intrigued to see what social
aspects would come about by this population of users sharing their
routes, way points, tags, &c.
