Life-logs can help users to store and search for information related to their everyday lives that could otherwise easily be lost. To this end, a wearable sensing technology can be used to collect all the various forms of information that can emerge during the course of an individual’s everyday life. However, the standards for the metadata used to integrate the information input from various sensors in existing sensing technologies have yet to be determined. In addition, as far as the search for large amounts of data is concerned, existing technologies do not have effective search systems that make use of queries requiring highly-advanced functions such as position information. In this study, the metadata standards for lifelog media search were defined. Moreover, a prototypical system with which to search for large amounts of life-log data, including spatial-temporal information, was developed using existing systems.
