Our everyday life has become increasingly enhanced through the progress of advanced information technologies. In particular, the daily lifestyles of urban residents have changed significantly because of smartphones that keep them continually connected to the Internet. As a result, citizens are able to access diverse information sources anytime and anywhere. However, the current progress of these digital technologies dramatically increases the possibility of cognitive overload. In this paper, we propose Ambient Bot, a notification system that ambiently presents practical everyday information to people. Ambient Bot requires people to wear a lightweight head-mounted display (HMD) that shows the real world through a camera attached to the HMD. Users see an empathetic virtual creature in the real world via augmented reality technologies. The empathetic creature not only speaks but presents everyday information that people might be interested in only when they focus their attentions on the creature itself. We first present a design approach for the Ambient Bot; then, we describe a prototype system and its evaluation through a user study.
