Ulawulo olukude sisixhobo sothumelo esingenazingcingo esisebenzisa itekhnoloji yale mihla yokufaka ikhowudi kwingcaciso yeqhosha, kwaye ikhupha amaza okukhanya nge-infrared diode.Amaza okukhanya aguqulwa abe yimiqondiso yombane ngummkeli we-infrared we-receiver, kunye ne-decoded yi-processor ukukhupha imiyalelo ehambelanayo ukufezekisa iimfuno zokusebenza ezifunekayo zokulawula izixhobo ezifana neebhokisi zokumisela.
Akuqinisekanga ukuba ngubani owasungula ulawulo olukude lokuqala, kodwa enye yeendlela zokuqala zokulawula kude yaphuhliswa ngumqambi ogama linguNikola Tesla (1856-1943) owayesebenzela u-Edison kwaye wayesaziwa ngokuba ngumqambi onobuchule kwi-1898 (i-US Patent No. 613809). ), ebizwa ngokuba “yiNdlela kunye neSixhobo sokuLawula iSithuthi esiHambayo okanye iZithuthi”.
Ulawulo lokuqala olukude olusetyenziselwa ukulawula umabonakude yinkampani yombane yaseMelika ebizwa ngokuba yiZenith (ngoku efunyenwe yiLG), eyaqanjwa ngeminyaka yoo-1950 kwaye yaqala yafakwa iingcingo.Ngomnyaka we-1955, inkampani yavelisa isixhobo sokulawula esingenazingcingo esibizwa ngokuba yi "Flashmatic", kodwa esi sixhobo asikwazi ukwahlula ukuba i-beam yokukhanya ivela kwi-remote control, kwaye ifuna ukulungelelaniswa ukuze ilawulwe.Ngomnyaka we-1956, uRobert Adler wavelisa ulawulo olukude olubizwa ngokuba yi "Zenith Space Command", eyayiyeyona nto yokuqala yesixhobo sokulawula esikude esingenazingcingo.Wasebenzisa i-ultrasound ukulungisa amajelo kunye nevolumu, kwaye iqhosha ngalinye likhupha amaza ahlukeneyo.Nangona kunjalo, esi sixhobo sinokuphazanyiswa yi-ultrasound eqhelekileyo, kwaye abanye abantu kunye nezilwanyana (ezifana nezinja) banokuva isandi esikhutshwa yi-remote control.
Kwiminyaka ye-1980, xa izixhobo ze-semiconductor zokuthumela kunye nokufumana imisebe ye-infrared zaphuhliswa, ngokuthe ngcembe zatshintsha izixhobo zokulawula i-ultrasonic.Nangona ezinye iindlela zothumelo ezingenazingcingo ezifana neBluetooth ziqhubeka ziphuhliswa, obu buchwephesha buyaqhubeka busetyenziswa ngokubanzi kude kube ngoku.
