Mental Task Evaluation for Hybrid NIRS-EEG Brain-Computer Interfaces

Table 5

EEG-NIRS fusion peak values for each subject and task pair, when using features extracted from one-second windows. Task pairs and participants are shown in descending order of average , from top to bottom and left to right, respectively. values between 0.4 and 0.7 (satisfactory performance) are highlighted  in italic font, whereas values greater than 0.7 (high performance) are shown in bold font. average peak time with standard deviation are also included for each task pair. .
