Instructions

  • Please use headphones — the audio is part of the evaluation
  • Rate how human-like and appropriate the body and arm movements feel for the speech
  • Focus on body and arm movement, not rendering quality, face, or voice
  • Each clip plays once through before you can rate it; you may replay it as often as you like
  • There are no right or wrong answers

About the avatar

  • The hand shape is fixed (open/flat) in every clip — an avatar limitation, not part of the motion. Please ignore the hands.
  • The clips may show different characters and settings. Focus only on how the body moves, not on visual appearance or rendering quality.
  • The clips vary in motion quality — some body movements will look more natural than others. That variation is what we are measuring.
