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

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

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

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

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
