Please let the list know how it works out.

If you look at MyLifeBits' graphs of data accumulation, they're
estimating 1GB a month. A month! And we're talking about 8-16GB a day
like it was the easiest thing in the world! The advance of technology
has outstripped Gordon Bell's testbed.
MyLifeBits is also just an archiving tool, a way to annotate and
organize these memories. But I don't think it says anywhere what Gordon
actually does with them once they're saved. How often does he reference
something he said or recorded or did? All the papers focus on indexing
and the technology side, not the personal, emotional and social side.
One project does look at the social side from an outdoorsy perspective:
http://www.whatdidwesee.org/
And another does it for photographs by location, in general:
http://wwmx.org/
But nothing on what a "normal" person does with all that data. It's not
explicitly at your fingertips; if you're recording your entire day on
one 8GB card, you can't access any of it until after you download it
overnight. Then, presumably, any points you've "bookmarked" have their
full video saved locally (say, five minutes before the mark and 10
minutes after), highlights and keyframes get pulled out ("scene" changes
like iMovie and Windows Movie Maker does) and both get superresolutioned
photo sets created, all automatically. The CF card gets erased, a DVD
is burned (although not so automatically if you have to flip it over),
and you're ready to grab the card when you get dressed. But only the
GPS tracks, "bookmarked" video and remaining highlight data is available
locally. Maybe all of the audio, too, after culling out blocks of
solely ambient noise. You annotate the timeline and excerpts, but how
much time a day do you devote to it? You're probably not going to go
back and fill in bits and pieces, swapping out DVDs to pull more clips,
things like that.
Are any of the wearable groups, GA, MIT, etc., looking at
mass-consumption applications? Have Thad and others posted detailed
logs of how they actually use their wearable over the course of the day?
How does it compare to looking up the same information through your
cell phone or PDA over Wi-Fi or EVDO, proxying your Google Desktop
Search results to your handheld? What comes up in conversation that
their wearable helps them recover? Is all the data local? What if you
don't have access to anything but the index and not the actual cached
data (e.g. being able to search Google but not view the full results)?
Is that still useful?
Thanks,
Vitorio Miliano
