PushPullWall : Interaction with Public Information System Using Smartphone for Exchanging Information

Abstract

This report proposes an interactive public information system called "PushPullWall" which allows users to post and get various kinds of information using their own smartphones in a manner like throwing information at the wall or catching information from the wall. The preliminary experimental results using a prototype system built for the proof of concept are shown. They encourage us to envisage the promising future of intuitive interactions between public information systems and smartphone-equipped users.
