Second Half Introduction • Design recommendations • The Social Navigator • Conclusions
Designing your own system • Integration Integral part of our everyday tools Phoaks/Alexa • Presence Presence can be communicated in several way, not only real-time presence
Designing your own system • Trust Trusting the advice provider Alexa/ICQ • Privacy Privacy for the advice provider ICQ/PowWow/Phoaks/Footprints
Designing your own system • Appropriateness When and how to connect people • Personalisation We as humans often tailors information e.g. PowWow online guides • Avatars physical limitations and “unnecessary” expectations Onlive Traveller/The Palace/ICQ
Example: The Social Navigator • A Framework for Social Navigation • Supports: • Indirect Social Navigation (ISN) • Direct Social Navigation (DSN) • Two parts: • Server • Client
Users Example: The Social Navigator • Server Architecture sam.sics.se The Web 1. http://sam.sics... 2 Social Navigator redirect: true getUsers: getUsers.jsp createUser: createUser.jsp 7 <html>.... <body> user1<br> user2<br> ... </html> 6 5 3 4 getUsers.jsp createUser.jsp Online Users
Example: The Social Navigator • Default Java Client 2 1 SNClient 5 3 4 WEB SERVER SNServlet
On-line food shopping (3D) • 3D Space • Chatting • Overview map
Recipe based food shopping • Collaborative filtering • Overview map • Chatting • Visualisation of user groups • Read wear
Connecting People - Conclusions • Purpose: • Show existing systems that connect people • Give design recommendations • Take a closer look at the Social Navigator • Some final advice: • Be careful with avatars • Try to keep things simple for the user • Examine existing systems before you build your own!
