Intelligent information agents
An information agent is a program that
– Access one or more than one information
source that is distributed and heterogeneous.
– Acquires and maintains relevant information
of its user and of other agents (preferably in a
‘just-in-time’ manner)

New ideas :
•
Distributed perception through communication
•
Robust behaviour with poor perception and movement
capabilities
•
Automatic behaviour recognition
•
Multiagent learning
Impact:
13
•
Tranfer of ideas to bigger robots
•
Perception, action and effective behaviour in
competitive tasks
•
Real-time reaction and quick adaptation to uncertain
and dynamic environments

Humanoids?
•
Why?
•
– Simulation(emergencies)
– Entertainment (movies, tv conductors)
– Medicine (virtual therapy, rehabilitation)
Avatars: representation of the user, sometimes with guided movement
Autonomous virtual humanoids with objectives and rules
– React to the environment, show behaviours, take decisions
– Reals (and believables) in shape, animation and behaviour
