Studies on how smart technology could be, well, actually smart and enhance social encounters rather than disrupting them. Design examples and a theoretical framework.

1. Personal ICT – a disruptor or
enhancer of face-to-face interaction?

2. CSCW & Enhancing collocated social interaction

Experiences, Communications of

3. Physically present,
mentally elsewhere
”phubbing”

4. ”Alone together”

5. Design space: roles of social technology
5
Invite interaction
• Increasing awareness
• Revealing common ground
& tickets-to-talk
• Matching
Encourage interaction
• Motivate or incentivize
people to interact
• Engage in collective activity
• Provoke & enforce
Enable interaction
• From one-user UIs to multi-
user interaction
• Possibilities for shared
experiences
Facilitate interaction
• Shared workspaces &
activities for collaboration
• Breaking ice
• Enriching means of soc.

6. Increasing Awareness of User Activity with a
Social Display
What if the activities with personal mobiles were more public?

Awareness of the User'sActivities. MobileHCI 2015.

(2016) Increasing Collocated People'sAwareness of Mobile User's
Activities: FieldTrial of Social Display. In proc.CSCW'16.
Design idea:
A second screen on the
backside to visualize cues
of the current activity
Can the increased
awareness lead to
opportunistic
interactions?

• Increasing awareness about the people in one’s
immediate surroundings in a playful way
Could gamification nudge nearby people to interact?

9. Proactive “Talking” Social Devices
to encourage interaction
Hello, good to
see you Lumia!
Hi, of you have
a new user!

Heh, I guess so….
Btw. I’m John.

11. Co-Cam – collaborative phototaking
Encouraging/enforcing interaction
• Asymmetry of interaction to
enforce interaction
• A field-based quasi experiment
comparing three different
methods

Could photography be turned
into a more social activity?

Work in Progress
Creating new social ties & encounters in professional life
• Computational methods for intelligent social matching of
people who complement each other
• Powered by Big Social Data, Social Network Analysis and
Machine Learning

How about using theTinder approach?

Our approach
Big Social Data for advanced profiling
“high-volume, high-velocity, high-variety and/or highly semantic data that is
generated from technology-mediated social interactions and actions in the
digital realm” Olshannikova et al. (2016)Conceptualizing
Big Social Data.Journal of Big Data.
Services for:
• Social networking
• Content sharing
• Socializing
• Profile/portfolio
How can we create comprehensive,
truthful and relevant professional
profiles with minimal BSD?
Thomas Olsson –Tampere University ofTechnology

17. 17
Social Network Analysis (SNA)
• Clusters & shortest paths
• Central / influential people & bridges between clusters
• Weak ties (Granovetter 1973) as potential ties
Thomas Olsson –Tampere University ofTechnology

18. • “How to utilize the potential and latent
weak ties in social big data in order to
enhance collaboration in knowledge
work?”
18Thomas Olsson –Tampere University ofTechnology

19. BSD and SNA in matchmaking
• Which analyses does Twitter data afford?
– Similarity: current interests, co-occurence
• Keywords, shared links, hashtags
– Network: mentions & followership (how truthful??)
19Thomas Olsson –Tampere University ofTechnology
What extent of diversity vs. similarity
is optimal in most cases?

20. How about DBLP?

21. Combining the analysis methods
Are these
enough?
21Thomas Olsson –Tampere University ofTechnology
Weak ties
Similarity
of interests
Differences
in skills &
BG
Most potential
• Relevant
• Trustworthy
• Complementary
Could we use supervised machine learning here?
Where and how to get the training data?

22. Early prototype of
“(Smarter) Tinder for professionals”
https://projects.invisionapp.com/share/C99YPF14U#/screens
• User & system co-creating the intelligence
• Transparency of recommendations
22Thomas Olsson –Tampere University ofTechnology

23. To conclude:
Yes, ICT is a social disruptor
– but it could be an enhancer, too
