Development of a life-logging platform using smart devices and its applications

Abstract

With the advance in sensing and related technology, smartphone and wearable device became the important machine for peoples convenient life with extensive data of user information like location or motion. These data are closest data from the user, collected literally on users hand. So using smart devices, we can figure out users status and log users daily life pattern more precisely. Applications about life-logging with smart device are got attention in this context. We propose life-logging framework which collects as various data as possible. In our framework, we propose not smartphone life-logging platform only or wearable life-logging platform only, but, an integrated life-logging platform that uses both of them. Proposed platform collect many data as possible with protecting generality, which means that user of various OS version can use this platform. Our platform can be applied in many application like a psychological experiment. To prove our platform is adaptable to many examples, in this thesis, we propose also inferring mood application that infers users current change of mood such that activeness-whether he or she is more active or less active than past- or happiness. We collected Application extracts features from collected data using proposed method.
