Scientists discovered how to capture sights and sounds , to record and replicate visual and audio information long ago . But automatically enchant sense of smell has proved trickier . Despite more than a century of evolving , ever more sophisticated audio - optical technology , scientists still do n’t have a satisfying method for record odour . But research worker David Harel of the Weizmann Institute of Science in Israel conceive he has create a theoretical organization that could , finally , help experts more accurately mimic aroma .
Popular Scienceexplains that Harel recently posted apaperto arXiv , an electronic archive , that imagines a theoretic example for bring on and assessing artificial scents . Harel explains that part of the challenge when it comes to replicating aromas is judging whether the replica are exact : While it ’s relatively well-off to look at a picture and judge whether it ’s an accurate internal representation of its subject , scent percept is more hard to judge . AsPopular Sciencenotes , not only do odors depend on our brain ’s percept of molecules , but human speech is loosely limited when it come to describing smell .
Harel argues that , in ordination to accurately replicate olfactory perception , a “ sniffer ” ( a gimmick which take apart a perfume ) and a “ whiffer ” ( which would create the replica scent based on the sniffer ’s analysis ) are necessary . Like a camera , the theoretical scent replicator would regurgitate perfume automatically .
But , for approximate the accuracy of this theoretic machine , argues Harel , something akin to theTuring Testwould be needed . While the Turing Test was design to decide the existence of artificial intelligence , Harel ’s test would pronounce the succeeder of hokey aromas . In heart and soul , Harel argues , the samara to creating replica aromas may rest as much in the tests we design to assess them as in the replicating technologies themselves . Harel pen , “ To put it merely , we would like to make certain that if and when bright method for artificial olfaction are proposed , we will be prepared with carefully worked - out valuation methods . ”
