Interaction management

[severin-lemaignan]

• interaction phases
• anticipation from the user
• inputs queuing or out of expected slots
• general robot attitude (boredom, angry...)
• physical time management (make sure we progress, do not get stuck in the same phase)
• "engagement management" "goal management" -> remind the teacher about the test phase
