• What did we learn?

– ‘Genuine’ Dynamics = More likeable/Trustworthy

– ‘Fake’ Dynamics = Less Likeable/Trustworthy

Conclusions and Future DirectionsConclusions and Future Directions

• Humans are very sensitive to different dynamics

• Different dynamics can produce dramatically different perceptual effects

• Understanding these effects is key for producing human-realism

• Technology now allows study of 3D dynamics - our work has only just started!
