If Intel prognosticated correctly, context is the future of apps --
your device's array of sensors will determine where you are and what
you're doing, and clever programs will guess from there. Problems
arise, however, when one tries to run those accelerometers,
microphones, radio antennas and GPS tracking devices constantly on the
battery life of an average smartphone and determine what the raw data
means, and that's where a group of Dartmouth researchers (and one
Nokia scholar) are trying to stake their claim. They've got a bundle
of algorithms called Jigsaw for iPhone and Symbian that claims to be
able to continually report what you're up to (whether walking,
running, cycling or driving) no matter where you place your device,
and only pings the sensors as needed based on how active you are. (For
better or for worse, Jigsaw also dodges the privacy concerns Intel's
cloud-based API might raise by storing all personal data on the phone.)
Of course, we've had a very basic version of context-aware
functionality for years in apps like Locale for Android -- which
modifies your smartphone settings under very specific conditions you
specify (GPS coordinates, WiFi locations, battery life and more) and
it just so happens that Espoo's doing much the same with an app called
Nokia Situations. Presently in the experimental stage, Situations is a
long ways away from the potential of frameworks like Jigsaw, but here
you won't have to wait -- you can download a beta for Symbian^3, S60
5th Edition and S60 3.2 at our source links without further delay.
