摘要: A 'Virtual Keyboard' (VK) is a letter spelling device operated by spontaneous EEG, whereby the EEG modulated mental hand and leg motor imagery. We report on tetraplegic patient initially trained an EEG-based orthosis control system operating VK. He achieved outstanding ability in use of VK can operate it with 0.95 letters per minute.
