Ho rekota ka botlalo scalp electroencephalography (EEG) hangata ho sebelisoa lits'ebetsong tsa khomphutha (brainI interface) tsa ts'ebetso tse nang le li-electrode cap tse ngata. Lintlha ha li na feela leseli le felletseng mabapi le ts'ebeliso, empa hape li na le tlhaiso-leseling e sa sebetseng le lerata tse etsang hore ho be thata ho senola lipaterone. Pampiri ena e hlahisa lipatlisiso tsa rona tsa pele molemong oa ho khetha menyetla e metle bakeng sa ho ithuta ho lemalla marang-rang ka pono ea "Oddball". Mohlala oa mekhahlelo e 'meli o sebelisitsoe ho khetha liteishene tse amehang ka ho fetisisa mabapi le mosebetsi ho tsoa liteisheneng tse felletseng tsa 64. Taba ea pele, liteishene li ne li beoa ho latela palo ea matla a khoheli ea motlakase (PSD) le palo ea Fisher ka thoko bakeng sa thuto ka 'ngoe. Taba ea bobeli, lenane la ho hlaha la mocha ka mong lipakeng tsa lithuto tse fapaneng le ile la thathamisoa. Liteishene tse hlahang ka makhetlo a fetang a mabeli li ne li kopanya hantle. Menyetla e metle le ho kopanya mefuta e meng ea lipapatso (ho kenyeletsa le liteishene tsohle) li sebelisitsoe ho khetholla pakeng tsa sepheo le sepheo se sa lebelloang ka mokhoa oa tlhahlobo oa khethollo ea Fisher linear. Liphetho tsa karohano li bonts'itse hore mokhoa oa khetho ea seteiti o fokolitse liteishene tse ngata haholo mme o netefatsa ho nepahala ha tatellano, ho hlaka le kutloelo-bohloko. Ho ka phethoa ho tsoa liphetho tsa hore ho na le khaello ea tlhokomelo ho batho ba lemaletseng marang-rang.
