THE CONVERSATION: Movement signatures: how we move, gesture and use facial expressions could be as unique as a fingerprint

Description

The way someone walks, talks, smiles, or gestures gives a clue to who they are. Whether through the flick of an eyebrow, the rhythm of our walk, or the tilt of a head, movement speaks volumes.

And my recent paper shows that people may have their own movement fingerprint. This is a style of movement that is characteristic of a person’s identity. So, someone who uses expressive facial gestures might also speak with animated hand movements or walk with a lively gait. These consistencies could form a motion fingerprint that is unique to the individual.
