The design and realization of three-dimensional visual stimulator for brain-computer interface

In order to meet requirements of brain-computer interface system for motor imagery, and provide effective visual stimulus. This paper combined three-dimensional modeling and motion editing techniques to design 3D visual stimulator for brain-computer interface. Proposed a view of goal-oriented process control, used pre-reading-rendering strategy, designed a multi-cache mechanism. In addition, we finished the parallel port communication between the data acquisition instrument of brain-computer interface and the visual stimulator. This system can accomplish high precise visual stimulation, guarantying the further study in how to enhance the control of EEG signals.
