Acquisition of the Life Log Using Home Electric Appliances and its Application

摘要

A life log records man's activity information as digital data. After these life logs are recorded, they are used in order to look back upon an individual's life. There are some problems in the method of life log acquisition. The system needs to install many sensors in a house. In order to install sensors, much initial investment is needed and the user's burden is heavy. Moreover, since the mental resistance is also strong to installing sensors in a house, introduction of the system takes time and effort. For the solution of these problems, we propose a method of acquiring and analyzing life log from Android based home electric appliances. In this study to develop an experimental system, the life log information which could be taken with Android home electric appliances is acquired by the simulated environment with home electric appliances with minimal sensors, and the life log is used and very rough life pattern is estimated. The reliability of the acquired log information is evaluated by getting subjects to live for one week in this system.
