The invention designs a control method to support accurate visual stimuli of a brain-computer interface. A software system implementing the method comprises a generator, an actuator and a controller. The generator automatically generates an image sequence according to test requirements. The actuator is a module running on a GPU. At the beginning of a trail, the controller asynchronously calls an interface of the actuator to start the actuator, and the actuator accurately shows the image sequence generated by the generator. At the end of the trail, the controller asynchronously calls an interface of the actuator to stop showing visual stimuli.
