Mobile Social Software

- Thinking about social interactions.
- Desktop -> Mobile Technology
- Mobile phones -> ubiquitous handheld computing

- Need to decide early on to use SMS or not

-Mobile phones thought to be intrusive
-Norms established for technology, etiquet, and rules.
-Private world invading public

-Location sensitive
- guides, games, matchmaking

Design considerations
-push vs pull, asking or pushed out

Wk4: Social Software

Wk4: Social Software

- Software that supports group interaction
- deals with groups not individuals.

8 Challenges (Grudin 1994):
1. Disparity in work & benefit
2. Critical mass & prisoners dilemma
3. Disruption of social processes
4. Exception handling
5. Unobtrusive accessibility
6. Difficulty of evaluation
7. Failure of intuition
8. The adoption process

Shirky 3 things to accept
1. You can't completely separate the technical and social issues.
2. Members are different than users
3. The core group has rights that trump individual rights in some situations

Shirky: 4 things to design for
1. Handles the user can invest in, penalties for switching, reputation management
2. Design a way for there to be members in good standing
3. Barriers to participation, has to be hard for some users
4. Spare the group from scale.

Understanding groups
- differs by size, composition of group
- conformity, norms, consensus

Wk3 Notes

CSCW Architecture:
- systems need to support multiple parties asynchronously and geographically distributed.

Centralised Architecture
- consistency easily achieved but slow doesn't scale well. Simple to understand-

Replicated Architecture
- Quicker, more responsive. Scales well, More complex. Difficult to keep consistent

Hybrid Architecture
- Responsive, Consistency but complex.

-WYSIWIS
-undo
-transparency, awareness
-synchronisation

-Methods for showing who your collaborating with and how.
