A Lifelog System Specialized to Record Timestamp of Daily Works

It has been long time passed from when research works that generate life log based on sensor data, information on blogs and SNSs. On the other hand, daily behavior of a particular students and employees are almost the same. Especially, it is better that recordings of which timestamps are important such as records of working time are based on these daily behaviors rather than based on data mining of blog and SNS data. Therefore, in this paper, life log system that is specialized to record timestamps, based on login, logout, and manipulation of equipment on building, such as to open and close of particular doors and locks is proposed. This system mainly focuses such an environment like university, where working time is not strictly recorded. As a prototype of the proposing system, a timestamp recorder is implemented based on only logins and logouts on particular PCs. In this paper, design of the proposing system and implementation of the prototype are described, and evaluation of the prototype will be shown.
