Academic Conferences as Social Spaces
• Conference settings– Specific time, space & focus– Community of people
w/ shared interests• Different sub-contexts,
different social interactions– Formal presentations
(papers, panels)– Semi-formal presentations
(demos, posters)– Informal events
(breaks, receptions)

Academic Conferences as Social Spaces
• Sites for mutual revelation– Hear what others are doing– Talk about what I’m doing– Professional & personal
• Revelation opportunities are unevenly distributed– Presenters vs. non-presenters– Veterans vs. newcomers
• How can technology help?

Proactive Displays
• Displays + sensors (+ algorithms + policies + …)– Large displays that can
sense & respond appropriately to the people nearby
• Issues for proactive displays:– Context(s): Where should they go?– Content: What should they show?– Control: How will they know?

Experience UbiComp Project
• Context(s)– UbiComp 2003
• Fifth International Conference on Ubiquitous Computing• Westin Seattle, 12-15 October

• Content– Web-based profile database– Name, affiliation, photo(s), …
• Control– Register, activate and wear RFID tags during the conference– Opt out at any time (delete profile, discard tag)

Caveats
• Existing communities at conferences– Variations in stature, approachability– Newcomers vs. veterans
• Technological interventions– Complete invisibility is undesirable– Augmentation vs. interference
• Privacy– Human subjects issues

Setting & Data Collection• Conference deployment: UbiComp 2003
– Medium-sized, single-track, conference– 500 attendees (50% from USA)– Two proactive displays:
• AutoSpeakerID (ASID) • Ticket2Talk (T2T)
• Systematic Observation– Observations + opportunistic interviews
• Post-conference Survey– Mix of multiple choice and open-ended response– 94 respondents (19% response rate)

Enhance Feeling of Community• AutoSpeakerID
It was nice to be able to see who was speaking to put their question in context if I didn't hear or forgot the person's introduction.
• Ticket2Talk I was chatting with someone I didn't know personally (small talk) about a recent presentation when I noticed his profile on the Ticket 2 Talk display and realized he was affiliated with an organization I really admire and would like to collaborate with ... Noticing this allowed me to redirect the conversation to that topic!

24www.proactivedisplays.orgMcCarthy, McDonald, et al.
Mesh with Established Practices
• AutoSpeakerID It seemed distracting - in the sessions I was in it seemed that virtually every person who approached the microphone began by commenting on the speaker ID (e.g. "oh it's working, yes that's me" or "it's not working for some reason").
• Ticket2Talk People walk up with a big smile. Look at the person standing next to
them and again at the display. Is that you?!? One is waving RFID tag in front of reader. Pick me up!

Manage Privacy Concerns
• Display agnostic (across both applications)– Unconcerned
... it might had been nice that [the research] community directory information was downloaded automatically.
– Concerned I didn't want all this information to be available to everyone - would rather have more control over who gets to see what ... and might want to highlight interests differently to different people.
