Dr. Xiangyu WANGAugust 18th, 2008

Why do we socialize in real life?

Examples of social technologies Digital cities, community networks, portals

such as eBay and Slashdot, and older technologies based on electronic bulletin board systems, newsgroups and mailing lists are just some of the examples of social interaction spaces.

Web as A Social Technology Web technology (e.g., blog and wiki) can

play an important role in enabling people to interact with each other.

The Web could afford sharing information and for connecting people to people.

Not just work together, better social interaction benefit working together.

Web as A Social Technology

A social technology should enable people to: Share experiences Expose tacit knowledge Make recommendations Discuss different topics Get to know other people Work together …

Importance of social interaction Design performance is also based on

social process. On-task and off-task during collaborative

work: Is coffee machine conversation off-task?

Sociability Sociability is the degree of promotion of a social

space or a network. How computer-supported collaborative

environments differ in their ability to facilitate the emergence of a social space?

What promote social interaction, social space? One thing is trust. A second aspect is belonging. The willingness to give

oneself up for the greater cause, the cause of the team. Example: Lance Armstrong's team

A third is temporal and physical proximity. We can see who was where doing what when.

Repeated social interactions Repeated social interactions are important

for: increasing familiarity, developing relationships, reminding people about what they have in

common, strengthening ties to an organization helping to develop a positive regard for the

social system

2002 conference to “extend the interaction opportunities…”
