WIRE3: Driving Around the Information Super-Highway

Abstract: Interactive voice browsers offer an alternative paradigm that affords ubiquitous mobile access to the WWW using a wide range of consumer devices. This technology can facilitate a safe, “hands-free” browsing environment that is of importance both to car drivers and various mobile and technical professionals. This paper describes the challenges of architecting an interactive voice browser that combines digital audio with the features of a speech synthesizer to make structural elements of the document explicit to the listener. The aesthetics of the audio rendition can simultaneously help reduce the monotony factor and enhance comprehension. The evolution of the voice browser gave rise to a new conceptual model of the HTML document structure and its mapping to a 3D audio space. A number of novel features are discussed for improving both the user’s comprehension of the HTML document structure and their orientation within it. These factors, in turn, can improve the effectiveness of the browsing experience.
