Abstract

We propose a system called Ubi-Jector, which provides a shared information screen utilizing participants' personal mobile devices in casual meeting places. This system can successfully substitute for a large projector screen in most conventional meeting rooms, such as cafeterias, lobbies, or libraries, and also enable all participants to communicate simultaneously through their mobile devices. In this paper, we first present the preliminary study results that characterize the current issues when a casual meeting is carried out without a large shared screen, and then identify a set of user requirements for the system design. Next we describe our early prototype implementation, user interface, and simple evaluation.
