Brain computer interface (BCI) are systems that can extract information from brainwaves to
control a computer or an external device. A computer cursor controlled by brain activity, one
of the interesting neuro-prosthetic devices in BCI, was first offered to the patients with spinal
cord injury using invasive measurements of brain activities. More recently, techniques based
on noninvasive measurements such as Electroencephalography (EEG) have become
popular. Here, we investigate the activation and control of a computer cursor in one …

Materials and Methods: The experimental procedure included three phases. During the
experimental procedure, EEG signals were acquired by using an Emotiv EPOC device with
14 channels and through BCI2000 software (with high pass filter at 0.1 Hz and low pass filter
at 30Hz). Phase 1 was the training phase. The subject was asked to sit comfortably in a fixed
chair with hands resting on the laps. The subject's face was kept at an arm's length from the
monitor. The subject was instructed to track the movement (up-down/right-left) of a computer …
