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
What Is Roadcasting?
CMU MHCI - GM Network Project 1 April 2004
ROADCASTING
Where we are, as of today:
21 group meetings
2 prototypes
14 users interviewed
92 pieces of content on project site

ROADCASTING
1. Project Focus Selection
Narrowed down ideas from an initial 45+ to five finalists.
Sketched and developed concept documents for each of the five.
Ranked the surviving three by all relevant criteria and chose the best.
How We Got Here

ROADCASTING
2. Design brainstorming
Found two main areas to consider:
How We Got Here
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

3. 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

4. Design Issues
How We Got Here
Issues for Participatory Design
•Community-building vs. personal aspects of radio
•Types of use (music, talk, etc.)
•Level of control desired
•Interaction desired with station
Questions for ourselves
•Does the concept of a “station” still make sense?
•Do users need to know which station they’re listening to?
•Issues of station ownership & community role

5. Participatory Design Session
To determine target audience’s in-car activities and music-related activities
Seven participants
Average age 31
5 males, 2 females
Averaged 48-minute round-trip commute

5. Participatory Design Session
Three activities

5. Participatory Design - Results
Questionnaire:
More participants listen to the radio than their own music
Vast majority of participants listen to FM stations
Participants listen to the radio primarily for entertainment, then for news
Most participants change stations after each song, or when commercials come on
Audience prefers music and comedy to political commentary

5. Participatory Design - Results
In-car activities collage
Participants’ Activities / Concerns:
1. Safety
2. Isolation
3. Radio
4. Personal music
5. Aggravation due to other drivers
6. Delays

How We Got Here
Number of times each button was selected. (Includes write-ins)

5. Participatory Design – Discussion
How We Got Here
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
CMU MHCI - GM Network Project 1 April 2004
ROADCASTING
6. Paper prototype
How We Got Here
Seeking information regarding:
Sending votes to a station
Blocking a station from one’s radio
Searching for stations
CMU MHCI - GM Network Project 1 April 2004
ROADCASTING
7. Prototype testing
Ongoing
So far:
Difficulty with testing: Metadata and classifications of internet radio aren’t perfect
Users disinclined to “block” a station
Some participants had trouble thinking of genres on their own (and would prefer browsing)
How We Got Here
CMU MHCI - GM Network Project 1 April 2004
ROADCASTING
8. Working prototype
How We Got Here
Seeking information regarding:
•How users browse through large numbers of stations
•How the browsing problem can be narrowed
•Ways to introduce collaborative filtering

What’s Next
Continue prototype testing of receiving
Iterate paper prototype
Implement collaborative filtering for Java prototype
Explore broadcasting
Has been delayed because audience needs and desired weren’t established
Create prototypes to test with real users
Continue to define larger-scale service and technical details
What’s Next

ROADCASTING
Much progress has been made
Timeline has proven to be fairly realistic but still need adjustments
