Into enomdla kukuba uthotho lwabaphandi Ikhaya likaGoogle, iSiri kunye ne-Alexa zigqekeziwe ngokubonisa ukukhanya kwelaser Kuzo ayizizo iindaba ngokwayo, enento yazo, kodwa akukaziwa ngokuqinisekileyo kuba aba bancedisi basabela ekukhanyeni ngokungathi kuyavakala.
Sithetha ngezi abancedisi abathathu basesichengeni sokuhlaselwa Babandezeleka ngeelaser “ezitofayo” ukukhanya okungaqondakaliyo kwaye ngamanye amaxesha kungabonakali kwizixhobo zokuvula iingcango, ukutyelela iiwebhusayithi okanye ukukhangela izithuthi.
Umncedisi, uSiri kunye ne-Alexa bagqekeziwe
Kwaye kumgama weemitha ezili-110 ukusuka apho unako iprojekthi ukukhanya okuphantsi kwe-laser ukwenza ezo nkqubo zelizwi zisebenze apho imiyalelo "itofwayo" ethi emva koko iphumeze iintshukumo ezahlukeneyo kakhulu. Aba baphandi baye bakwazi ukuthumela ezi ntlobo zemiyalelo yokukhanya ukusuka kwesinye isakhiwo ukuya kwesinye kwaye badlule kwiglasi ukufikelela kwisixhobo kunye noMncedisi kaGoogle okanye uSiri.
Ukuza kuthi ga ngoku sinokuthi, uhlaselo luthatha ithuba lokuba sesichengeni esikhoyo kwiimakrofoni kunye noko isebenzisa into ebizwa ngokuba yi-MEMS (iinkqubo ze-micro-electro-mechanical). Amacandelo e-MEMS eMicroscopic aphendula ngokungaziboli ekukhanyeni ngokungathi isandi.
Kwaye ngelixa abaphandi baye bavavanya olu hlobo lohlaselo kuMncedisi kaGoogle, uSiri, Alexa, njenge nakwi-portal ye-Facebook kunye nochungechunge oluncinci lweepilisi kunye neefowuni, baqala ukukholelwa ukuba zonke izixhobo ezisebenzisa i-microphone ze-MEMS ziyakwazi ukuhlaselwa yile nto kuthiwa "Imiyalelo yokukhanya."
Uhlobo olutsha lohlaselo
Olu hlobo lohlaselo lunoluhlu lwemida. Eyokuqala yileyo Umhlaseli kufuneka abe nomgca othe ngqo wokujonga kunye nesixhobo lowo ufuna ukuhlasela. Okwesibini kukuba ukukhanya kufuneka kugxininiswe ngokuchanekileyo kwindawo ethile ye-microphone. Kwakhona khumbula ukuba ngaphandle kokuba umhlaseli usebenzisa i-laser ye-infrared, ukukhanya kuya kubonwa lula nguye nabani na okufutshane nesixhobo.
Oko kwafunyanwa kolu ngcelele lwabaphandi kubaluleke kakhulu ngenxa yezizathu ezithile. Akunjalo nje ngenxa yokuba ukwazi ukuhlasela olu luhlu lwezixhobo ezilawulwa ngelizwi ezilawula izixhobo ezibalulekileyo ekhaya, kodwa kwakhona. ibonisa indlela uhlaselo olunokwenziwa ngayo phantse kwiindawo zokwenyani.
Eyona nto itsala ingqalelo enkulu ukuba isizathu se "physics" asiqondwa ngokupheleleyo yemiyalelo yokukhanya eba yinxalenye ye "exploit" okanye ubuthathaka. Ngapha koko, ukuba ibisaziwa ngenene ukuba kutheni isenzeka, bekuya kuthetha ulawulo olukhulu kunye nomonakalo kuhlaselo.
Kukwayamangalisa ukuba olu luhlu lwezixhobo ezilawulwa ngelizwi Abaphathanga naluphi na uhlobo lwephasiwedi okanye iPIN efunekayo. Oko kukuthi, ukuba uyakwazi "ukugqekeza" ngolu hlobo lokukhutshwa kokukhanya, unokulawula lonke ikhaya apho uMncedisi kaGoogle okanye uSiri elawula izibane, i-thermostat, ukuvala umnyango kunye nokunye. Phantse njengemuvi.
Ukuhlaselwa kwexabiso eliphantsi
Kwaye sinokucinga ukuba ukuba ne-laser light projektha kunokubiza kakhulu. Okanye ubuncinci iindleko zokukwazi ukwenza ukuhlaselwa kwesi simbo zaziphezulu. Hayi akunjalo. Olunye ulungelelwaniso lohlaselo lubandakanya indleko ye-390 yeedola kunye nokufumana i-laser pointer, umqhubi we-laser kunye nesandisi sesandi. Ukuba sizii-gourmets ezininzi, songeza iilensi ze-telephoto nge-$199 kwaye sinokujolisa kumgama omkhulu.
Unokuzibuza ukuba ngubani na abaphandi abasemva koku kufunyanwa okumangalisayo okubonisa indlela entsha yokuhlasela uluhlu lwezixhobo esizibeka sonke kumakhaya ethu. Kulungile sithetha ngayo Takeshi Sugawara weDyunivesithi ye-Electro-Communications eJapan, kunye noSara Rampazzi, uBenjamin Cyr, uDaniel Genkin kunye noKevin Fu weYunivesithi yaseMichigan. Ngamanye amazwi, ukuba nangaliphi na ixesha ubucinga ukuba sithetha ngentelekelelo, hayi kwaphela, into eyinyani epheleleyo.
Omnye uhlaselo olutsha loMncedisi kaGoogle, uSiri kunye nezixhobo ze-Alexa ezinelizwi ngemiyalelo elula kwaye oko kuya kuba nomsila kwiminyaka ezayo; uMncedisi kaGoogle odibanisa ne-WhatsApp, ke khawufane ucinge into enokwenziwa ngolu hlaselo.
