Carpet uses biometrics and piezoelectronics sensors to create
a pressure sensitive mat underneath the carpet. This mat allows
the 'magic carpet' to calculate the footprint size, weight and
height of each person walking on it. The system, checking this
information against the 'footprints' stored in it's memory,
is able to 'recognise' family members.
carpet also allows the family to 'authorize' friends to enter
the home ... however, if someone tries to enter without any
of the family members present the system will identify them
as an intruder, sound the alarm and store the intruders data
for use as evidence by the police.
