It s green but is it the right green

It’s green, but is it the right green?


Goal based interaction with autonomous systems

Goal-based Interaction with Autonomous Systems

  • No useful system is completely autonomous

    • People set goals, redirect activities, approve plans

    • Goal-based interaction is a challenge

    • Contact with autonomous systems can be intermittent

  • What should be the content of intermittent dialogues?

  • How can we depict and interact with goals and plans in context

    • Support humans’ situation awareness of automaton(s) in action


Depicting plans in context

Mission Goals in Operational Context

Depicting Plans in Context

Goal & Plan Abstraction

How do we extend this to complex, fluid, antagonistic operational domains?

How do we depict user expectancies about the result of goal accomplishment?
