Which 3D reconstruction is better?

A short study on 3D reconstructions of people interacting with objects · around 5 minutes

✓ Your task

Each screen shows a photo and two rotating 3D reconstructions of it, A and B (person in blue, object in orange). Pick the one that better matches the interaction in the photo.

Where the object is relative to the person: position, orientation, and where they touch.
Contact is more important than penetration. If the photo shows touching, a slight intersection is better than a gap.

✓ Better sits in the chair, slightly sunk in

✗ Worse floats above the chair

✗ Ignore
