Abstract

We developed a lifelog system that utilizes user's mobile phones. User's position, which is closely related to the user's activity and experience, is tracked by GPS in outdoors and by a newly developed positioning system utilizing signal strength of Bluetooth in indoors. The mobile phone is also equipped with a supplementary function that lets the user record his/her current activity by simple key stroke. Lifelog experiment for 76 consecutive days has been carried out using these positioning systems and logging tool. Analysis on lifelog data and some useful parameters for predicting user's next behavior are presented.
