A steady-state visual evoked brain-computer interface performance evaluation method based on eye movement tracking

The invention relates to a steady-state visual evoked brain-computer interface performance evaluation method based on eye movement tracking. Firstly, a measuring electrode, a reference electrode, a ground electrode and an output end of the electrode are respectively arranged on a user's head according to the standard, and are connected with a computer through a collector and an EEG signal amplifier. Then, according to the size of the computer screen, an eye-movement meter is placed in the center, and the eye-movement meter is connected with the computer; Then the eye movement instrument is calibrated and a target recognition task is carried out. After multiple identification tasks, the accuracy of the recognition result is calculated, The visual fixation position parameters collected by the eye movement instrument are calculated, and the accuracy rate and the visual fixation position parameters are presented to the user through the computer screen, so as to realize the evaluation of the steady state visual ev
