24.8Listen carefullytothe footsteps inthe familyhome,especially ifit haswooden floors,andyoucan probablywork outwho itis thatis walkingabout.The featuresmost commonlyused toidentifypeople arefaces,voices,finger printsand retinalscans.But their^behavioural biometrics^,such asthewaythey walk,are alsogiveaways.Researchers have,for severalyears,used videocameras andcomputers to analyse peoplesgaits,and arenow quitegood atit.But translatingsuch knowledgeintoapractical identificationsystemcan betricky——especially ifthat systemis supposedtobehidden.Cameras areoftenvisible,are hardto setup,requi5re good lighting andmayhavetheir viewblocked byother people.So ateam ledby KrikorOzanyan ofthe Universityof Manchester,in England and PatriciaScully oftheNational Universityof Ireland,in Galwayhavebeenlooking fora betterwayto recognize gait.Their answer:pressure-sensitive mats.In themselves,such matsare nothingnew.They havebeen part of security systems fordonkeys9years.But Dr.Ozanyan And Dr.Scully usea complexversion thatcan recordthe amountofpressure appliedin differentplaces assomeone walksacross itThese measurementsform apatternunique tothe walker.Dr.Ozanyan andDr.Scully thereforeturned,as isnow commonforanything todo withpatternrecognition,toanArtificial Intelligencesystem thatuses machinelearningtorecognizesuch patterns.It seemsto work.In astudy publishedearlier thisyear thetwo researcherstested theirsystemon adatabase offootsteps troddenby127different people.They foundthat itserror rateinidentifying who was whowasamere

0.7%.AndDr.Scully saysthat evenwithout adatabase of■一footsteps to work withthe systemcan determinesomeones sexwomen andmen,with wideand（骨盆）narrow pelvisesrespectively,walk indifferent ways,---and guess,with reasonableaccuracy,a subjectsage.A mat-based gait-recognition systemhas theadvantage thatit wouldwork inany lightingconditions——even pitch-darkness.And thoughit mightfail toidentify someoneif,say,she waswearingstilettos andhad beenentered intothe databasewhile wearingtrainers,itwould be veryhardto foolit byimitating thegait ofan individualwhowasallowed admissiontoaparticular place.The latestphase ofDr.Ozanyan9sandDr.Scullys projectisaredesign ofthe mat.The old行（光mats containedindividual pressuresensors.The newones containoptical bres纤）.（二极管）Light-emitting diodesdistributed alongtwo neighbouringedges ofamattransmit（）light intothe fibres.Sensors onthe oppositeedges andthus theopposite endsoftheoptical fibresmeasurehow muchof thatlight isreceived.Any pressureapplied topartofthematcauses a（变形）distortion inthe fibresandaconsequent changeintheamount oflight transmitted.Both thelocationand amountof changecanbeplotted andanalyzed bythe machine-learning system.Dr.Ozanyan saysthat theteam havebuilt ademonstration fibre-optic mat,two meterslong（）andametre wide,using materialsthat cost£100$

130.They arenowtalking tocompanies aboutcommercializing it.One applicationmight bein healthcare,particularly forthe elderly.A fibre-optic matinstalled ina nursinghome oran oldpersons ownresidencecould monitorchanges inan individuaPsgait thatwarn certainillnesses.That wouldprovideearly warningof someonebeing atgreaterriskof fallingover,say,orof their cognitionbecomingdamaged.Gait analysismight alsobeusedass asecurity measureintheworkplace,monitoring accesstorestricted areas,such asparts ofmilitary bases,server farmsor laboratoriesdealing withharmfulmaterials.In thesecases,employees wouldneed toagree totheir gaitsbeing scanned,just astheywould agreetothescanning oftheir facesor retinasfor opticalsecuritysystems.Perhaps themost fascinatinguse ofgait-recognition mats,though,wouldbein publicplaces,such asairports.For thatto work,thefootstepsof thosetoberecognized wouldneed tohave beenstoredinadatabase,which wouldbe harderto arrangethan thecollection ofmugshots andfingerprintsthat existingairport securitysystems relyon.Some people,however,might volunteerforit.Many aircrewor pre-registered frequentflyers wouldwelcome anythingthat speededup oneofthemosttiresome partsof moderntravel.
