NRC and Dartmouth College develop activity tracking smartphone application
From the New Scientist comes an update on "Jigsaw", a smartphone application that can keep track of your daily activities and environment for analysis or for sharing with others:
Jigsaw figures out what you are doing by monitoring your phone's microphone, GPS and accelerometer for patterns characteristic of routine activities - and it could be set to send the results to social networking sites.
More importantly, Jigsaw can log how active you are each day, producing records that could be useful to a doctor or fitness trainer. Its pattern-recognition algorithms can identify a range of behaviors, making its logs more detailed than those of similar apps, says Hong Lu at Dartmouth College in Hanover, New Hampshire, who developed the app in collaboration with the Nokia Research Center in Palo Alto, California.
For example, the jolts produced when the user is walking depend on whether the phone is in a trouser or jacket pocket, so the software can recognise both patterns. Information from the other sensors helps to further define the activity.
