ROADCASTING
More niches to support than even 150 radio stations can handle
Even internet radio not interactive
Untapped opportunity to make radio more entertaining, reach a broader, captive, audience

ROADCASTING
?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

ROADCASTING
1. Design brainstorming
Found two main areas to consider:
Progress Since Last Presentation
Broadcasting•Definition and maintenance of live playlist
•Opportunities for commercials
•Deciding when and where to broadcast
•Differentiation from “real” radio
•Feedback regarding audience
•On-air light
•Signal quality
•Location of source music
•What happens when DJ reaches destination
Receiving•Definition of a station
•Locating a desirable or desired station
•Notification of new stations
•Dealing with non-persistent stations
•Identifying stations uniquely
•Definition of types of searching and browsing
•Avoiding undesirable or “bad” stations
•Agent guidance
•Definition of desirable filtering criteria

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

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

3. Participatory Design – Discussion
Progress Since Last Presentation
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
Seeking

4. Paper prototype
Progress Since Last Presentation
Seeking information regarding:
Sending votes to a station
Blocking a station from one’s radio
Searching for stations

ROADCASTING
5. Working prototype
Progress Since Last Presentation
Seeking information regarding:
•How users browse through large numbers of stations
•How the browsing problem can be narrowed
•Ways to introduce collaborative filtering

7. 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.

What’s Next
Continue prototype testing of receiving
Iterate paper prototypes
Implement collaborative filtering for Java prototype
Explore broadcasting
Has been delayed because audience needs and desired weren’t established
Create prototype that fakes the receiving end to better understand broadcasting issues
Work towards a combined unit that can be distributed to users “in the wild”
Continue to define larger-scale service and technical details
