Abstract: Hewlett Packard Laboratories, GWR, Bristol University, ASL and Panasonic Semiconductor are collaborating in a Mobile Bristol project to explore the potential of Digital Audio Broadcasting through a series of user trials. Our first iPAQ-based prototype allows listeners to GWR FM to interact with a set of web pages broadcast alongside the digital audio stream and displayed on a small colour display. In a hands-on study, typical GWR listeners responded very positively to the experience of viewing web pages on a visual radio. Local news, weather forecasts, event listings, and details of the last ten songs broadcast proved especially popular. In forthcoming experiments, we will begin to explore the additional value of a wireless backchannel enabling listeners to interact directly with the broadcaster, for example to vote for records or take part in contests, and the opportunities created for DAB by broadband wireless and location-sensitive services.
