Kuyambira kumapeto kwa zaka za m'ma 1960 ndi koyambirira kwa m'ma 1970, zojambulajambula zambiri zam'madzi zidasinthidwa ndi ndege ndi Aerospoce Electro-Sypor exror systerms. Kujambula kwachikhalidwe kwamyambo kumathandiza kwenikweni pakuwoneka kowoneka bwino, mpweya wamakono wamagetsi ndi njira zamakono zopangira digito woyatsa digitor, zomwe zimawonetsedwa, zopondera zopondera, ndi madera a micherove. Njira zachikhalidwe zotanthauzira zachikhalidwe mu zojambula za Aerial zikuthandizabe. Komabe, kumverera kwakutali kumaphimba ntchito zambiri, kuphatikizapo zochitika zowonjezera monga mtundu wa chizolowezi cha zomwe tikufuna, miyeso yowoneka bwino ya zinthu, ndi kusanthula kwa digito kuti mupeze chidziwitso.

Kuzindikira kutali, komwe kumatanthauza njira zonse zosagwirizana, ndi njira yomwe imagwiritsa ntchito election electromacagnam kuti mudziwe, kujambula ndi kuyeza mikhalidwe ya chandamale ndipo tanthauzo lake lidafunsidwa koyamba mu 1950s. Gawo la Kutayika Kwakutali ndi Kumapukiza, imagawika mitundu iwiri yazovuta: yogwira ntchito yogwira ntchito, yomwe imatha kugwiritsa ntchito mphamvu zake, zomwe zimatha kugwiritsa ntchito mphamvu zake kuti ziwoneke ku chandamale ndikuwona Kuwala komwe kumawonekera.
