Xaudio: Results from a Field Trial Study on a Technology Enhancing Radio Listeners’ User Experience

Abstract

This paper discusses a field trial of a technology (Xaudio), which connects two different types of media: The mobile internet and the radio. Inaudible signals (watermarks) are broadcasted via the sound of the radio, are received by a mobile device and decoded. This information then is used to take the listener directly to a mobile application (Xaudio application) that is relevant to the radio content currently broadcasted. Ten persons participated in a field trial study on this technology. The paper presents the results of this field trial. In particular it compares different kinds of applications and analyses the reasons for their success or failure. Furthermore proposals to improve the service of Xaudio for future uses are discussed briefly.
