The system includes one or more processors in communication with non-transitory data storage media having instructions stored thereon that, when executed by the one or more processors configure the one or more processors to perform particular steps. The steps include: receiving, at an electroencephalogram (EEG) receiver, baseline EEG data; and acquiring, using a normalisation module, one or more normalisation factors from the baseline 00 EEG data. The steps further include: receiving, at the EEG receiver, stimulated EEG data sensed by one or more EEG sensors; and correlating the stimulated EEG data across the one or more EEG sensors, using a correlation module, to generate one or more correlation 00 coefficients corresponding to one or more stimulation frequencies, each of the one or more stimulation frequencies corresponding O to a respective candidate control command. The one or more normalisation factors are then applied to the one or more correlation C [Continued on next page] WO 2018/182534 Al MIDEDIMOMOIDEIREEM311101110110MMEHOIS HR, HU, ID, IL, IN, IR, IS, JO, JP, KE, KG, KH, KN, KP, KR, KW, KZ, LA, LC, LK, LR, LS, LU, LY, MA, MD, ME, MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.

A control stimulation frequency is then identified, from the one or more stimulation frequencies and using the one or more processors, based on the one or more flattened correlation coefficients. acquiring, using a control command identification module, the control command by determining which said candidate control command corresponds to the control stimulation frequency.
