Abstract

A wireless BCI input system for mobile intelligent devices is described. The system may include an SSVEP keyboard for stimulating SSVEP signals and an EEG headband for acquiring EEG signals. The SSVEP keyboard may include sixteen virtual buttons and a mask that can be replaced to change functions of the virtual buttons. The EEG headband may include an EEG acquisition module, an EEG analysis module, and a Bluetooth communication module, which are used for acquiring EEG signals, determining the user's input intentions, and sending characters or controlling commands to a matched mobile intelligent device via Bluetooth connection.
