Now your smartphone can broadcast your every action

摘要

Can't be bothered to tell your Facebook friends what you are up to? A smartphone app called Jigsaw can help. 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.
