WPT: A toolkit for publishing a web-based lifelog

Abstract

This paper describes a toolkit for implementing lifelog applications that automatically generate web-based reports about daily lives from sensor data such as GPS data, acceleration data, and camera images that capture our daily activities. To design the toolkit, we collect example lifelog applications using a questionnaire survey where we ask participants what kinds of daily life data they want to record for later use and then clarify their characteristics. Based on the obtained information and our view, we realize an infrastructure that provides automatic report publishing and development support for generating reports from sensor data. © 2011 Springer-Verlag.
