Measuring passers-by engagement with AmPost: a printed interactive audio poster

Abstract

This paper presents AmPost, a prototype of an interactive audio poster, which integrates ink-jet printed sonic and tactile elements along with textual and graphical information. This enables users to directly interact and engage with the poster. To achieve a seamless paper-based interactive poster that includes printed interactive elements, we implement a printed speaker and audio feedback system directly into the paper-based medium, which plays a short tune when someone walks by. Engaging passers-by with this new interface becomes a challenge as posters, in general, are non-interactive. This paper also presents an initial empirical evaluation of AmPost that captures and analyses the frequency and length of user engagement, and evaluates whether user engagement improves with the integration of interactive features, in comparison to the traditional non-interactive poster. This study facilitates in building the generic approach to measure engagement that applies to any kind of posters.
