Conclusions
Current virtual worlds
difficult to adopt for educational needs
Creation of interactive objects
time-consuming
requires high programming competence
Tutor concentrated on tool instead on
didactics

Conclusions
VirtualLife
supplements learning with on-line interactions
simplified installation
content creation
supported by rich interactive object library
web generator
facilitates creation of searchable learning materials
advanced features
decrease the need of face-to-face activities
