Abstract

A traditional life-log is written in the first-person viewpoint since a user collects data using sensors worn on the body. A UbiGraphy that we introduce here is a third-person viewpoint life-log that is made possible by the spontaneous interaction between a wearable computer and smart objects in a ubiquitous computing environment. A wearable computer uses smart objects in the proximity to capture a user's smiles, poses, and even songs from the third-person viewpoint, and then write a life-log where a user appears. This paper presents the design of a protocol that enables UbiGraphy and our first prototyping effort for experiencing UbiGraphy.
