Summary

• Objectives
• Case-Based-Reasoning
• Experience-Based-Reasoning
• Articulation with psychological investigations
• Driving "traces"
• Driving Frames and schemas
• Proposal

Objectives

• Better understand driver's cognition.
• Implement assistance systems adapted to driver's
  current mental state.
• Partnership between the vehicle and driver
• Based on sequences that have been learned by both
  of them.

4
Case-Based-Reasoning

• To solve a new problem by remembering a previous
  similar situation and by reusing information and
  knowledge of that situation. (Aamodt Plaza,
  1994)
• Apply CBR to the case of an uninterrupted data
  flow.

5
Experience Based Reasoning

• Applications
• a) System performs the solution by itself
  (artificial cognitive agent)
• b) System assists a human operator (assistance)
• c) System "imitates" the operator's cognition
  (cognitive modelling)
