conclusion first day:
virtual worlds will change our way of communication and work
- virtual worlds are mainly used for social interaction
- need of interfaces, standards to integrate business applications, secure payment systems and mobile devices
- universal avatars would be great
- tendency to closed worlds for communication networks in companies, open source solutions are preferred
- additional marketing tool for companies
- people use their avatars as a toy
- an avatar is always a substitute of the real human being behind and shows - wanted or not - wishes and unconscious behaviour
All in all a confirmation what I already know, but not to bad.
