Architectures of laboratory-PC and mobile pocket PC brain-computer interfaces

An EEG-based brain computer interface (BCI) system converts brain activity into control signals. A BCI system has to satisfy different demands depending on the application area. A laboratory PC based system allows the flexible design of multiple/single channel feature extraction, classification methods and experimental paradigms. The key advantage of a pocket PC BCI approach is its small dimension and battery supply. Hence a mobile BCI system e.g. mounted on a wheelchair can be realized
