Culture Matters in Humanness Recognition for Human Body Motion

How to generate human-like motion is a hot topic emerging from the human-motion generators propelled by AI techniques.The first "humanness" evaluation based on human perception provided the basic principles of how we express and understand humanity in body movements, but it is unknown whether these principles are universally applicable.We conducted a comparative study between two Asian cultural cohorts, revealing that Taiwanese performers predominantly utilized kinematic cues and exhibited higher motion energy, while Japanese performers relied on their distinct human life experiences to convey humanness.Our results with two culturally proximal groups demonstrated that designers should recognize the influence of cultural context on the performance and perception of humanness, highlighting the necessity for broader cross-cultural and multi-regional investigations to refine our comprehension of human motion cues, and to advance computer-human interaction on a global scale.
