Abstract

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