Title: Adopt A Walk
Description:
And so on, and so on, and so on.
By stealing the walk of another person do I become someone else?
This is an audio-guide of an experiment of gait analysis,
If you never heard about this term, gait analysis is the study of patterns of walk during ambulation used by new surveillance biometric technologies.
People are asked to walk following a series of spoken instructions. The walks are stored temporarily on a page where you’re invited to “adopt a walk” of another person.
“Have you ever tried to look at the way a person walk as a way to identify her?
Surveillance technologies are using the homogenic perception of human being as a model for their mechanics.”
With this experiment you’re invited to observe characteristic of walks your similar and adopt them. Try to imagine that in modifying your walk you could escape from detection of your identity.
