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 and GPS-Action for Symbian -- which modifies your smartphone settings under very specific conditions you specify. Now, 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.
