Brain - Computer interface based on Steady - State Visual Evoked Potentials (SSVEP)

The paper describes a virtual keyboard based on a brain-computer interface, controlled by Steady-State Visual Evoked Potentials (SSVEP). Steady-State Visual Evoked Potentials are natural responses when the retina is excited by a visual stimulus ranging from 3.5 Hz to 75 Hz. The SSVEPs are characteri...

More Information
Summary:The paper describes a virtual keyboard based on a brain-computer interface, controlled by Steady-State Visual Evoked Potentials (SSVEP). Steady-State Visual Evoked Potentials are natural responses when the retina is excited by a visual stimulus ranging from 3.5 Hz to 75 Hz. The SSVEPs are characterized by an increase in EEG activity around the stimulus frequency. The SSVEP component has been detected using Welsch's method. The Virtual Keyboard is characterized by high signal-to-noise ratio (SNR).
