New approach to community and communication Service model that allows people to express themselves by offering their own radio stations Allows communities to meet and share common interests Provides methods for quickly finding the best stations for any individual listener CMU MHCI - GM Network Project 19 April 2004 ROADCASTING • The state of radio • What is Roadcasting? • Progress since last presentation • 1.

Design brainstorming Found two main areas to consider: Broadcasting Receiving •Definition and maintenance of live playlist •Definition of a station •Opportunities for commercials •Locating a desirable or desired station •Deciding when and where to broadcast •Notification of new stations •Differentiation from “real” radio •Dealing with non-persistent stations •Feedback regarding audience •Identifying stations uniquely •On-air light •Definition of types of searching and browsing •Signal quality •Location of source music •What happens when DJ reaches destination CMU MHCI - GM Network Project •Avoiding undesirable or “bad” stations •Agent guidance •Definition of desirable filtering criteria 19 April 2004 ROADCASTING Progress Since Last Presentation 2. Contextual Inquiries User research with contextual inquiries at college radio station WRCT Watched on-air activities performed by each of three DJs Concluded that in-car broadcasting can be much simpler, and feasibility is not as bad as we thought CMU MHCI - GM Network Project 19 April 2004 ROADCASTING Progress Since Last Presentation 3. Participatory Design Session To determine target audience’s in-car activities and music-related activities Three activities Questionnaire In My Car collage Dream Radio collage CMU MHCI - GM Network Project 19 April 2004 ROADCASTING Progress Since Last Presentation 3. Participatory Design – Discussion Radio as Controlled Chaos Current radio is marketing songs Satellite radio is an improvement but still does not offer sufficient breadth of programming Participants appreciate “good” DJs CMU MHCI - GM Network Project 19 April 2004 ROADCASTING Progress Since Last Presentation 4. Paper prototype Seeking information regarding: Sending votes to a station Seeking Blocking a station from one’s radio Searching for stations CMU MHCI - GM Network Project 19 April 2004 ROADCASTING Progress Since Last Presentation 5. Working prototype Seeking information regarding: •How users browse through large numbers of stations •How the browsing problem can be narrowed •Ways to introduce collaborative filtering CMU MHCI - GM Network Project 19 April 2004 ROADCASTING Progress Since Last Presentation 6.

Scalability No listeners: Systems selects songs from personal collection based on driver’s personal preferences. 1 listener: Station begins to tailor its track recommendations to agree with tastes of both the broadcaster and the listener. 10 listeners: Because of taste diversity, the identity of the station begins to exert itself through the broadcasters selections, and certain genres become more popular than others. 1,000 listeners: Fluctuations in individual listener’s preferences have little impact. Voting becomes an optimal way to gauge audience’s taste. Note: Broadcaster always has the option for full control of song selection.
