A sustainable information kiosk driven by sound

In this paper we describe nibble.io, an offline information kiosk that has been designed for deployment within the rural communities of developing countries. We show how a pervasive technology such as sound can be used as a method of interaction between low-end feature phones and information kiosks built using standard PC monitors. By connecting an embedded computer to a monitor we show how we are able to create an interactive experience driven by the user's phone using a variety of interfaces ranging from music players to web browsers.
