The present application relates to a visual stimulation system, a visual stimulation generation method and a brain-computer interface system. The visual stimulation system includes a display device for displaying a stereoscopic image, a first polarization filter device for allowing polarized light of a first frequency to pass therethrough, and a second polarization filter device for allowing polarized light of a second frequency to pass therethrough. The display device displays visual stimulation blocks of the same size but different frequencies at the same position and at the same time. Both the first polarization filter device and the second polarization filter device are arranged on the side of the display device that emits the visual stimulation block. The coding of the visual stimulation system belongs to dual-frequency coding, the types of visual stimuli generated by the visual stimulation system are adjustable, and it is not easy to generate wrong instructions. The visual stimulation system uses polarized light of different frequencies to completely isolate the left and right visual fields of the subject, and it is almost impossible for the information of the two frequencies to merge before entering the optic chiasm.
Description
technical field [0001] The present application relates to the technical field of human-computer interaction, and in particular, to a visual stimulation system, a method for generating visual stimulation, and a brain-computer interface system. Background technique [0002] At present, people are investing more and more time in mobile phones and computers, which have gradually surpassed traditional TV and books. And with the development of technology, more and more derivatives such as tablet computers, e-books, etc. are emerging. Of the many technologies that have evolved around cell phones and computers, the type of operation, or how it operates, is one of the most compelling. For mobile phones, it has transitioned from button control to pen touch control, and finally entered the era of finger touch. For computers, the combination of keyboard and mouse has always provided users with a convenient operating experience. The wireless mouse and infrared control technology that a...
