Title:
The Smart Floor: A Mechanism for Natural User Identification and Tracking
Authors:

Abstract:
We have created a system for identifying people based on their
footstep force profiles and have tested its accuracy against a large pool
of footstep data. This floor system may be used to transparently identify
users in their everyday living and working environments. We have created
user footstep models based on footstep profile features and have been able
to achieve a recognition rate of 93% using this feature-based approach.
We have also shown that the effect of footwear is negligible on
recognition accuracy.
