Claim 0:
1. A sensory floor comprising:
a sensory flooring system comprising:
a plurality of flooring segments; and
for each flooring segment, one or more electrode portions each electrode portion being responsive to a force applied to the flooring segment,
wherein at least one electrode portion of a said flooring segment forms an electrode with at least one electrode portion of another said flooring segment,
wherein each flooring segment comprises a unique encoding of the one or more electrode portions; and
wherein each electrode portion of each flooring segment is electrically connected with at least one electrode portion of another said flooring segment, to form an electrode;

a receiver for receiving an electrical output from the one or more electrodes formed by said one or more electrode portions of the flooring segments; and
a processor for analysing the electrical output and identifying the flooring segment by which the electrical output was produced, wherein the processor is configured to use a deep learning model to:
sense a position of a user based on the electrical output; and
detect a pattern of at least one of a magnitude of the electrical output and a sequence of flooring segments producing the electrical output, to identify a particular user as “valid” or “invalid” based on the pattern, the processor comprising a neural network configured to detect, based on features extracted from an output of each respective electrode, features corresponding to the particular user.
