Expressive Behaviours in LIREC companions:

Basic movement behaviours:

  • approach <position>
  • retract from <position>
  • move along <line>
  • approach <object/character/person> <social distance>
  • follow <object/character/person> <social distance>
  • turn <angle>
  • turn-back
  • orient-towards <object/character/person> <social distance>

Interaction with the environment

  • pick <object>
  • drop <object> <position>
  • carry <object>

Social/Communicative? ones:

  • greet <character/person>
  • listen <character/person>
  • talk <character/person> <speech-act>
  • nod <character/person>
  • look at <position/object/character/person>
  • touch <position/object/character/person>

Other more complex behaviours:

  • play
  • run
  • jump
  • get up
  • lie down
  • eat

Emotional Expressions (which can be parameterized with intensity value)

The six basic ones:

  • Joy
  • Anger
  • Disgust
  • Sadness
  • Surprise
  • Fear
  • Mood. ???
  • Motivational ????

Other states that we may want to capture:

  • Confusion
  • Dominance

Parameters that provide expressivity in the behaviours:

  • effort* of the movement (space; weight; time; flow)
  • shape of movement


*Effort, or what Laban sometimes described as dynamics, is a system for understanding the more subtle characteristics about the way a movement is done with respect to inner intention. The difference between punching someone in anger and reaching for a glass is slight in terms of body organization - both rely on extension of the arm. The attention to the strength of the movement, the control of the movement and the timing of the movement are very different. Effort has four subcategories, each of which has two opposite polarities.

  • Space: Direct / Indirect
  • Weight: Strong / Light
  • Time: Sudden (or Quick) / Sustained
  • Flow: Bound / Free
