Abstract

In this paper, we propose a life log viewer that gives the users new findings from life logs in daily life, and provides seamless integration with external information. We classify life logs into two types. "Unintended life logs" are recorded automatically without the user's direct input; "intended life logs" are recorded purposefully by the user. Based on this classification, we implement a prototype that has two characteristics. First, it can visualize a user's unintended life log from long-term and multi-dimensional points of view. Second, its user interface is designed to visualize the transitions from the analysis results of the unintended life log to event data in the intended life log, and from event data in the intended life log to search results that provide information about the events. We believe that this viewer is a stepping-stone to the "Life Portal" that integrates existing portals with life log analysis to create a stimulus for search initiation.
