This paper describes the ongoing project called Virtual Time Machine. The VTM project aims to realize to experience future and past events by long-term storage of information as well as prediction of future events by simulations using the storage of information. In this project, we studied the effective use of wearable computer for logging and visualizing a personal life. In this paper we discuss three prototype experiments we performed, location logging, speech logging and the logging with various sensors. We tried to "tag" the long-term storage of experiences by some logged sensors for future use. The first two experiments were performed to log data for comparatively long term in everyday situation. And the last one was performed to log data under a particular event. In each experiment, we evaluate whether the captured data is effective for use as a "tag" for indexing the daily experience for constructing a life log data structure.
