Evaluation of different spelling layouts for SSVEP based BCIs.

Brain-computer interface (BCI) systems enable humans to communicate with their environment by directly using brain signals. This way, body movement is not explicitly required for communication making this technology especially useful for people with limited mobility. In this study, the system performance and well-being of 38 subjects are investigated using two different layouts of graphical user interfaces (GUI) presented on a computer screen.

Our series of primary surgery cases with standardised parotidectomy technique in a university hospital were evaluated. Medical records of 295 patients treated from 1987 to 1999 were reviewed, and 171 patients answered a questionnaire about long-term sequelae.
