1. Chapter 24 Collaboration Technologies

2. Collaboration technologies
Development of communication technologies
IT -> ICT
TV/radio -> telephon ->
computer supported cooperative work
same/different place
same/different time

3. Groupware questions additional work for the individuals vs benefit
prisoner’s dilemma
critical mass
may not handle exceptions and improvisation
evaluation is close to impossible
requires much adoption

4. Technical infrastructure
Internet, 5G
heterogenity in network conditions is problematic
web2.0: helps bridging hardware/OS differnces (e.g. browser-based IM tools)
smartphone, tablet, smart watch vary in computational power, display size, connection reliability etc…

5. e-mail First successfull computer supported communication technology
PC, smartphone, smartTV, public terminals…
spam, virus, malware etc
communication differences between f2f and !
power of people, tone interpretation
information overload
automatic categorisation/spam filtering
tagging, importance ranking (explanation?)
supporting composition (e.g. missing attachment)

6. Computer-mediated communication
Video+Audio (videoconf room, PC, phone)
Audio (voice over IP)
Text (instant messaging, chat, SMS)
differs from f2f!
more formal, no paralinguistic communication, mike-passing, less socializing, no eye contact, shared workspace…

7. Blog/microblog 500M tweet/day
microblogs are important at many situations, even emergency…

8. Meeting support systems
Structured: system controls the processes
brainstorming, prioritisation, voting stb.
anonimity is possible (more effective but usually slower)
group access to a single document (´90)
more creative tasks (design, req analysis)
Elektronic whiteboard

9. Workflow systems issues, transaction flow efforts vs benefit
exception handling is problematic
monitoring users

10. Repositories of shared knowledge
sharing, storing, reusing the knowledge
Wiki
community editing,
control,
various creator/editor roles,
rules
version control (capturing older states)

11. Social networks
information- sharing and finding, gaming, shoping, event organisation, dating, professional forum
Recommender systems
Collaborative filtering
more trust in friends’ preferences than unknow people

12. Chapter 27 Online Communities

13. Online communities
„The cyberspace is the new frontier in social relationships and people are using the Internet to make friends, colleagues, lovers and enemies”
Communities form based on joint interest rather than phisical closeness

14. MMORPG virtual 3D world, interaction with other players
world „exists” when a user is offline
social interactions are important
in-game vs. out-game, guild
virtual and real worlds are blended
EverQuest
various virtual relationships (e.g. marrige)

15. Analysing online communities
Interview
Log analysis
Content and text
analysis
Social network analysis
network of participants and their attributes
egocentric vs non-local patterns
dynamics

16. Summary Computer supported human-human interactions
Collaboration technologies
