• HCSM Framework for Behavior and Scenario
  Control in Virtual Environments

organizing the behaviors of simulated agents
modeling the behavior of an reactive (autonomous)
agent
IDS (Iowa Driving Simulator)
Hierarchical, Concurrent, State Machine
3
Why HCSM?
Hierarchical, Concurrent, State
Machines poor reusability and
extensibility simultaneous attention to many
aspects of the environments arbitration for
resolving conflicting demands for limited control
resources
Single-level, Non-concurrent, State Machines
abstraction and encapsulation!!!
