Comparative total computing time (in seconds) of single trial analysis for different empirical data between conventional full-scan beamformer and reduced scanning beamformer with our proposed strategy. Source region with a total of 8,640 scanning points and a temporal window of 500 time samples were used. Experiments were conducted on a PC (Intel Core 2 Duo CPU 2.4 GHz, 32 bit OS, and 4 GB RAM).
