"A NEW FORM OF automated prejudice is set to make business decision-making far more efficient. The intelligent carpet, invented in Japan, can tell ... the age, sex and weight of the person walking across it. Analysis of the data collected can determine foot size, stride, walking speed, weight and centre of gravity of those ambling innocently along. The prototype carpet can distinguish between people in their 20s and 60s with nearly 100 per cent accuracy, acoring to a story on Nikkei.net. The carpet can determine a walker&amp;#039;s gender with 70-80 per cent accuracy, the inventors claim, since males and females have different centres of gravity."^^<http://www.w3.org/2001/XMLSchema#string>
