Calculatin scores of mental impacts for operators, I prepared example from today’s morning session (see images below):
Timing: relationship between background recording time and impact time. It should be equal or >3 (in web plots timing is always =3). For <3 the data are not reliable enough.
Sigma impact: (mean of background region)/(mean of impact region). It is calculated automatically and available as a separate bar diagram. Important parameters that says how strong was the impact (how strong is currently the operator)
Delay between begin of mental impact and begin of response of EIS dynamics. Another parameter that points to concentration time of the operator and its capability for mobilizing mental resources.
Mismatch between impacted channel and responded channel and intended change of trend (‘+’ or ‘-‘) and real change of trend.
Thus, web interface needs only 3 parameters for manual input from operator: sigma, delay and mismatch.
Protocol for operators: it is strongly advised to follow the following protocol: 1) relaxation phase 5-10 minutes; 2) remote impact I (strong phase), 5-10 minutes; 3) remote impact II (relaxed phase), 5-10 minutes. All phases are well recognizable in the EEG dynamics (see below). Total time for a session is thus 15-30 minutes.
