Abstract

ßrain machine interfaces (BMls) enable us to control extern al devices using our brain signals. Using a grid-shaped flicke ring line-Array and a shrink-rLDA c1assifier, top-down information could recently be decoded in a steady-state visual evoked potential (SSVEP)-based BMI pamdigm. The present study tested its feasibility in online implementation. We found that within reasonable computing time (0.114 s on average) its online system was successfully accomplished with a decoding accuracy of 53.7% on average. The accuracy was 3.2 times significantly high er than the accuracy by mndom-shuffled data (16.7%). Therefore, using the grid-shaped SSVEP-based BMl, one's muIticlass (at least 6 c1asses) intention can be online decoded and subsequently control extemal devices.
