Study on Robot Grasping System of SSVEP-BCI Based on Augmented Reality Stimulus

Although notable progress has been made in the study of Steady-State Visual Evoked Potential (SSVEP)-based Brain-Computer Interface (BCI), several factors that limit practical applications BCIs still exist. One these is importability stimulator. In this study, Augmented Reality (AR) technology was introduced to present visual stimuli SSVEP-BCI, while robot grasping experiment designed verify applicability AR-BCI system. The offline determine best stimulus time, online used complete task. revealed better information transfer rate performance could be achieved when stimulation time 2 s. Results indicate all 12 subjects control task, which indicates AR-SSVEP-humanoid (NAO) This verified reliability system and indicated AR-SSVEP-NAO tasks.
