Into enelukuluku lokuthi abacwaningi abaningi I-Google Home, iSiri ne-Alexa zigqekezelwe ngokuveza ukukhanya kwelaser kuzo akuzona izindaba uqobo lwazo, ezinento yazo, kodwa namanje akwaziwa ngokuqinisekile ngoba laba basizi baphendula ekukhanyeni njengokungathi kunomsindo.
Sikhuluma ngalezi abasizi abathathu basengozini yokuhlaselwa bahlupheka ngama-lasers "afaka" imiyalo yokukhanya engazwakali futhi ngezinye izikhathi engabonakali kumadivayisi ukudala iminyango ukuvula, ukuvakashela amawebhusayithi noma ukuthola izimoto.
Kusiziwe umsizi, uSiri no-Alexa
Futhi kukude ngamamitha ayi-110 lapho ungakwazi khona phrojektha i-low-frequency laser light ukwenza kusebenze lezo zinhlelo zezwi lapho imiyalo "ijojowe" khona-ke yenza izinhlobonhlobo zezenzo. Laba bacwaningi bakwazile nokuthumela lezi zinhlobo zemiyalo elula kusuka esakhiweni esisodwa kuye kwesinye futhi badlula ngengilazi ukufinyelela kudivayisi nge-Google Assistant noma i-Siri.
Ngokwazi kwethu, ukuhlaselwa kusizakala ngobungozi obukhona kumakrofoni nalokho sebenzisa lokho okubizwa ngokuthi yi-MEMS (amasistimu we-micro-electro-mechanical). Izingxenye ze-Microscopic MEMS ziphendula ngokungahlosi ekukhanyeni njengomsindo.
Futhi ngenkathi abacwaningi beluhlolile lolu hlobo lokuhlaselwa kumsizi weGoogle, uSiri, i-Alexa, njenge ngisho nasengosini ye-Facebook nochungechunge oluncane lwamathebulethi nezingcingo, baqala ukukholelwa ukuthi wonke amadivayisi asebenzisa imakrofoni ye-MEMS athinteka ekuhlaselweni yilokhu okubizwa nge- «Light Commands».
Uhlobo olusha lokuhlasela
Lezi zinhlobo zokuhlaselwa zinemikhawulo eminingi. Esokuqala ukuthi umhlaseli kufanele abe nokubona ngqo kudivayisi ofuna ukumhlasela. Okwesibili ukuthi ukukhanya kufanele kugxilwe ngqo engxenyeni ethile yombhobho. Kumele futhi kwaziwe ukuthi ngaphandle kokuthi umhlaseli asebenzise i-infrared laser, ukukhanya kuzobonakala kalula kunoma ngubani osondelene nensiza.
Ukutholwa kwalolu chungechunge lwabacwaningi kubaluleke kakhulu ngezizathu ezimbalwa. Hhayi kuphela ngenxa yokuthi uyakwazi ukuhlasela lolu chungechunge lwamadivayisi alawulwa ngezwi ekhaya aphatha amadivayisi athile abalulekile, kepha futhi ikhombisa ukuthi ukuhlaselwa kungenziwa kanjani cishe ezindaweni zangempela.
Okudonsela ukunakwa okuningi ukuthi isizathu se- "physical" asiqondakali ngokuphelele yemiyalo elula eba yingxenye "yokusizakala" noma ukuba sengozini. Eqinisweni, ukwazi ukuthi kungani kwenzeka lokhu empeleni kungasho ukulawula okukhulu nokulimala ekuhlaselweni.
Kuyamangaza futhi ukuthi lolu chungechunge lwamadivayisi alawulwa ngezwi ungaphathi uhlobo oluthile lwephasiwedi noma imfuneko ye-PIN. Okusho ukuthi, uma ukwazi "ukuwagenca" ngalolu hlobo lokukhishwa kokukhanya, ungalawula ikhaya lonke lapho i-Google Assistant noma i-Siri ilawula khona amalambu, i-thermostat, izingidi zeminyango nokuningi. Cishe njenge-movie.
Ukuhlaselwa ngezindleko eziphansi
Futhi singacabanga ukuthi ukuba ne-laser light projektha kungakubiza. Noma okungenani izindleko beziphezulu ukuthi zikwazi ukwenza ukuhlaselwa kwalesi sitayela. Akunakwenzeka. Esinye sezilungiselelo zokuhlaselwa sifaka izindleko ze- $ 390 ngokutholwa kwesikhombi se-laser, umshayeli we-laser nesikhulisi somsindo. Uma sesivele sithola ama-foodies amaningi, sifaka i-telephoto lens ngo- $ 199 futhi singakwazi ukukhomba amabanga amakhulu.
Ungase uzibuze ukuthi obani abacwaningi ngemuva kwalokhu okutholayo okumangazayo okukhombisa indlela entsha yokuhlasela uchungechunge lwamadivayisi esiwabeka emakhaya ethu. Kuhle sikhuluma ngakho UTakeshi Sugawara wase-University of Electro-Communications eJapan, noSara Rampazzi, Benjamin Cyr, Daniel Genkin, noKevin Fu waseYunivesithi yaseMichigan. Ngamanye amagama, uma ngesinye isikhathi ubucabanga ukuthi sikhuluma ngefantasy, cha, iqiniso.
Una ukuhlaselwa okusha kwe-Google Assistant, amadivayisi asebenza ngezwi e-Alexa ngemiyalo elula futhi ezoba nomsila eminyakeni ezayo; Umsizi we-Google ohlanganisa ne-WhatsApp, ngakho-ke cabanga kancane ukuthi yini engenziwa ngalokho kuhlasela.
