摘要: This paper presents a brain-computer interface game that controls spacecraft has to avoid obstacles in space route. The neural mechanism is based on steady state visually evoked potentials (SSVEP) combined with phase tagging. Two flickering stimuli are used move the left or right. tagged offset of 180° between them. Phase extraction applied narrowband frequency SSVEP. frequencies were selected 3-5 Hz range provides high level comfort. being developed be tested as neurotherapy tool for children Neurofibromatosis Type 1, showing attention deficits. Since usability major issue clinical use, was designed controlled single electroencephalographic (EEG) channel, and requiring calibration time less than two minutes. Pilot experiments performed group five healthy adults game, achieving performances above 95% accuracy 5 second trials.
