Electrical device control system and method based on SSVEP

摘要

In the electric device control system based on the SSVEP, Yusa Bu state-detection Moshi Bu ule can detect the behavior of Yusa Bu over, such as in a state that both eyes closed over a specific period of time. The system control unit can activate the visual stimulus generator set in response thereto. Each visual stimulus generator can output a visual signal presented at a unique frequency. It is possible to selectively attends to a visual stimulus generator of specific related to the interface electrical or a particular device, EEG acquisition unit to capture the EEG signal associated with SSVEP, which is generated by the brain of Yusa Bu over in the meantime Yusa Bu over. Device identification Moshi Bu ule to identify a visual stimulus generator which generates an EEG Ha ° Wasuhe ° vector amplitude te Bu over data related to the fundamental frequency F _k particular, it is determined that the main frequency F _D, and outputs a visual stimulus in presenting a frequency equal to F _D. The system control unit, operating state of the electrical device that sends to Maruchite Bu Bu Ha chair interface unit control commands of the electrical device, related to the visual stimulus generator that has been identified is changed.
